Glove manufacturing apparatus and method of manufacturing gloves

The present application is a divisional application of patent application 200980112184.8 entitled "glove manufacturing method and manufacturing apparatus and gloves made with the method or apparatus" filed 3, 25, 2009.

Technical Field

The present invention relates to a glove manufacturing method and manufacturing apparatus in which a glove insert is bonded to the inside of the glove shell material.

The present invention claims priority from the prior application of patent application (Tokugan)2008-077740 filed on 25/3/2008 and international application PCT/JP2008/063578 filed on 29/7/2008.

Background

Gloves for use in sports such as mountain climbing and skiing have a glove insert made of a waterproof film interposed between an outer layer material and an inner layer material. As a method of bonding a glove insert between an outer layer material (surface material) and an inner layer material of a glove, it is known to use a thermoplastic resin (patent document 1). Since the insert is capable of self-forming into the shape of a glove, in bonding such an insert to the glove skin material, a hand-shaped mold is used, the glove skin material and the glove insert are fixed to this mold, heated and compressed from the outside, and a bonding operation is performed by melting a molten thermoplastic adhesive coated on the outer surface of the glove (patent document 1).

Disclosure of Invention

Problems to be solved by the invention

However, if such a hand mold is used, it is necessary to prepare a plurality of molds suitable for gloves of various styles and shapes, resulting in excessive cost. Also, even with such a mold, it is not possible to provide the required heat and pressure to the thermoplastic adhesive between the glove shell material and the glove insert by means of external heating and compression, and thus, problems such as partial non-adhesion or insufficient adhesion may occur, and in addition, the glove insert may be partially detached from the shell material and the inner layer material during use of the glove. These all reduce the durability of the glove.

In addition, when a mold is used, the bonding operation needs to be manually performed one by one, which is time-consuming, high in defect rate and extremely low in productivity.

An object of the present invention is to provide a glove manufacturing method and apparatus capable of controlling instability of adhesion between an outer material of a glove and an insert of the glove to improve efficiency of operation, prevent deformation of the glove, and finally improve productivity.

Means for solving the problems

The method of manufacturing a glove of the present invention is characterized in that the glove insert is bonded to the inside of the glove shell material. After the glove insert coated with the adhesive on the outer side is inserted into the inner side of the glove outer material, gas is introduced into the glove insert by the gas introduction means, and the glove insert is inflated to bond the glove outer material and the glove insert together.

According to the present invention, when gas is introduced into the glove insert coated with the adhesive on the outside through the opening of the glove insert, the glove insert is inflated by the gas and bonded to the glove skin material under the gas pressure, so that the glove skin material and the glove insert are bonded together by the adhesive therebetween.

The preferred adhesive of the present invention is a thermoplastic adhesive, and for the heat treatment of the thermoplastic adhesive, the following two heat treatment methods can be satisfied: one is heat treatment in a heating furnace to bond the glove skin material and the glove insert, and the other is hot gas is charged into the glove insert to bond the glove skin material and the glove insert. When the heat-treated glove is cooled, it is preferable that the glove insert is cooled in a state where the glove insert is inflated with gas. If the gas is removed immediately after the heat treatment, the glove skin material and glove insert will not adhere sufficiently because the hot thermoplastic resin has not yet completely cured. In addition, the cooling treatment is preferably a natural cooling method.

In addition, further pressure is applied to the glove insert during the heat treatment, and the pressure in the glove insert is preferably increased compared to the initial stage of the heat treatment. In doing so, considering the easy deformability of the glove exterior material, when the glove insert is bonded, by using a control cover for controlling the deformation caused by the abnormal expansion of the glove exterior material due to the gas filled in the glove insert, the deformation of the glove exterior material can be controlled in many cases, thereby controlling the product defect rate and improving the productivity. In addition, by applying sufficient pressure to the inside of the glove insert to firmly bond the glove insert and the glove shell material, a glove can be made wherein the instability of the bond between the glove insert and the glove shell material can be controlled.

In the heat treatment, the time for performing the treatment in a pressurized state due to the application of the pressure is preferably 3 seconds to 20 seconds. If the time is less than 3 seconds, the glove insert and glove skin material will not bond firmly; if the time exceeds 20 seconds, the glove skin material Ts will elongate and fail to return to its original shape.

During the heat treatment, the pressure at the initial stage of the heat treatment is preferably more than 0.0001MPa and less than 0.003 MPa; after applying the pressure, the increased pressure is preferably greater than 0.003Mpa and less than 0.05 Mpa.

If the pressure in the initial stage of the heat treatment is not more than 0.0001MPa (0.001 kg/cm)²) A gap may be formed between the glove exterior material Ts and the glove insert Ti, and if pressure is applied thereafter, the glove exterior material Ts and the glove insert Ti may not be sufficiently bonded, and thus, there may be a gap in which the bonding is not sufficient locally, and sufficient bonding strength may not be obtained.

In addition, if the pressure at the initial stage of the heat treatment exceeds 0.003MPa, the glove skin material Ts is deformed.

If the pressure increased by the applied pressure is not 0.003MPa, the glove insert and the glove skin material are not firmly bonded.

When the pressure increased by the application of the pressure exceeds 0.05MPa (0.5 kg/cm)²) The glove shell material Ts will likely elongate and fail to recover.

After the gas is filled into the glove insert through the gas filling device, the glove insert is expanded, and the glove outer layer material is firmly bonded with the glove insert; desirably, the gas filled in the glove insert is isolated by a gas isolation means to control the outflow of gas that has been filled in the glove insert; separating the glove support members for supporting the glove skin material and glove inserts from the gas-filling means and moving the glove support members to a heating oven.

In this case, since the means for inflating the gas into the glove insert Ti and the means for heat treatment (heating furnace) are separable, it is possible to separately manage the gas-inflating means and the heating furnace. For example, one gas filling device can be provided with a plurality of heating furnaces to perform heat treatment in a preferred manner. In addition, a plurality of gas injection devices may be provided for one heating furnace, and the gas injection process may be preferably performed.

Also, it is suitable to use a gas filling device and fill hot gas into the glove insert by means of the glove support member, transfer the glove support member into a heating oven, and heat the thermoplastic adhesive in the heating oven to soften or melt it. In this case, although the thermoplastic adhesive may soften or melt in the hot gas, it is preferred that the thermoplastic adhesive is preheated in the hot gas, i.e. the thermoplastic adhesive is first preferably at a temperature at which it does not melt, after which the thermoplastic adhesive is preferably softened or melted by heating in a heating oven.

The glove manufacturing apparatus of the present invention is characterized in that, wherein the glove insert is bonded to the inside of the glove skin material; the glove manufacturing apparatus has a glove supporting member for supporting the glove member and holding it in a state where the glove insert has been inserted into the inner side of the glove outer layer material; the glove manufacturing apparatus also has a gas inflator for inflating gas into the glove insert.

According to the present invention, with the glove support member, the glove member can be held in a state where the glove insert has been inserted inside the outer material of the glove, and the glove insert can be inflated after the gas is filled into the glove insert by the gas filling means. Thus, when the glove insert, the outer surface of which is coated with the adhesive, is inserted into the outer material of the glove and then inflated through the opening of the glove insert, the glove insert and the outer material of the glove are bonded together under the air pressure as the glove insert is inflated, and the outer material of the glove and the glove insert are firmly bonded together due to the adhesive therebetween.

In the present invention, the glove support unit has a hollow interior passage, and preferably, the gas filling means is connected to the glove support unit. According to the present invention, it is possible to inflate a gas from a gas inflator into a glove insert and to support the glove support member from the outside, for example, by means of a glove support member having a hollow inner passage, and therefore, it is not necessary to perform a complicated operation such as inflation of a gas or the like by means of the gas inflator.

In the present invention, the glove support part is provided with a gas isolating means for controlling the outflow of gas thereon, and the glove support part is preferably connected with a gas pressure adjusting means for preventing the gas pressure of the gas filled in the glove insert from exceeding a certain value. In addition, the glove support member is fixed to the turn table so as to be easily mounted and dismounted at any time, and is transferred to a heating furnace located at a specific position on the turn table by the rotation of the turn table, and then the thermoplastic adhesive is softened and melted, and after a specific interval time has elapsed, the glove support member is returned to the inlet/outlet port, and thus, the efficiency of the bonding operation for bonding the glove insert to the inner side of the glove exterior material is improved.

The present invention preferably has a heating furnace. Thus, after the gas is filled, the heat treatment can be rapidly carried out, thereby improving the working efficiency.

The invention preferably has an engagement means for connecting the glove support means to the gas inflation device, and the engagement means preferably has a valve mechanism. In this way, after the glove support member is detached from the engagement member, outflow of gas from the gas inflator can be prevented. Thus, the internal pressure of the gas charging device is stabilized, the work efficiency of the gas charging process is improved, and unnecessary waste of the gas is not caused.

Using the method and the apparatus, a glove as described in the present invention can be manufactured.

Effects of the invention

According to the invention, the glove insert is inflated by the inflation gas, the glove insert is bonded to the glove shell material, and the adhesive provides an adhesive bond between the glove shell material and the glove insert. Thus, the instability of the bond can be controlled and a suitably shaped glove can be made simply by the expansion of the glove insert under the action of the gas. The gas filling means is relatively simple and, in addition, by using a rotary table to transfer the glove parts with the glove inserts inserted in the outer layer material to a heating furnace provided at a specific position on the rotary table to soften and melt the thermoplastic adhesive, an improvement in the efficiency of the bonding operation for bonding the glove inserts on the inner side of the glove outer layer material and an improvement in productivity can be expected.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

First embodiment of the present invention

Fig. 1 is a perspective view of a glove manufacturing apparatus according to a first embodiment of the present invention, and fig. 2 is a sectional view of the glove manufacturing apparatus. Fig. 3 is a perspective view showing a state in which the glove support unit 3 is fixed to the turn table 2. Fig. 4 is a modular plan view illustrating the arrangement of the heating furnace 5, the cooling chamber 11, and the preheating chamber 12 on the turntable 2.

The glove manufacturing apparatus 1 of the first embodiment of the present invention has a turntable 2 and a heating furnace 5 on a base, and a glove supporting member 3 on the turntable 2. On the glove support 3, the gas filling means 9 and the pressure regulating means 8 are joined together by the shaft 4. The glove support member 3 is provided with a gas isolation device 7.

Gloves suitable for manufacturing the present invention include ski gloves, mountaineering gloves, and gloves having a long wrist portion, such as fire gloves and cold gloves, and have a glove insert (also called waterproof insert) Ti on the inner side of the glove shell material Ts for waterproofing and windproof purposes. In addition, the glove insert Ti of the glove final product is provided with an inner layer material on the inner side thereof with an insulating material therebetween, and also, when the inner layer material of the glove insert Ti is formed of a fabric layer, the glove insert is suitably used.

The glove support member 3 functions as a support by covering the opening of the glove exterior material Ts and the glove insert Ti, and in the present embodiment, the glove support member 3 holds the glove member T in a state where the glove insert Ti is inserted onto the glove exterior material Ts. The glove support unit 3, together with a plurality of units provided around the turntable 2, enables a plurality of glove units T to be processed simultaneously (see fig. 4). The glove support 3 is fixed to the turntable 2.

The turntable 2 is rotated together with the glove support unit 3 in a fixed state, and the heating furnace 5 is provided on the top surface of the turntable 2. The preheating chamber 12 and the cooling chamber 11 are provided at positions near the front end and the rear end of the heating furnace 5, respectively. That is, there is a structure in which an inlet/outlet 6 is located at the front side of the turn table 2, a heating furnace 5 and the like are located at the rear side, and, when the turn table 2 is rotated once with the glove support part 3, which glove support part 3 is used to support the glove part T and is fixed at the inlet/outlet 6 on the turn table 2 by the coupling part 10, the preheating chamber 12, the heating furnace 5 and the cooling chamber 11 are aligned and returned to the glove support part 3, which glove support part 3 is used to fix the glove part T at the inlet/outlet 6 (see fig. 4).

The wall 2d divides the rotary turret 2 into specific regions, and a screen 2c is fixed to an opening formed in the wall 2d to form the heating furnace 5, the cooling chamber 11, and the preheating chamber 12. The heating furnace adopts means such as a circulating type heating heater, an infrared heater, an electric heater, fuel gas and the like to heat. The preheating chamber 12 can be heated by hot air flowing out from the heating furnace 5 through a space formed by the partitioning curtain 2c between the heating furnace 5 and the preheating chamber 12, in addition to the same heating means as the heating furnace 5, i.e., a circulation type heater, an infrared heater, an electric heater, a gas, and the like.

Before heating in the oven 5, the glove member T is preferably preheated, supported on the glove support 3, at a temperature between the temperature inside the oven and the room temperature. In addition, a ventilation fan or the like is used in addition to the air introduced from outside the cooling chamber to the cooling chamber 11 by the blower; the temperature in the cooling chamber 11 is lower than that in the heating furnace 5 due to the use of an air cooling device by means of a cooling medium; the flow of the heated air from the heating furnace 5 to the cooling chamber 11 is controlled by the separation screen 2c between the heating furnace 5 and the cooling chamber 11, and therefore, the temperature in the cooling chamber 11 is lower than that in the heating furnace 5, and the glove members T supported on the glove support members 3 can also be cooled.

The preheating chamber 12 is provided from the viewpoint of stability of the internal temperature of the heating furnace 5, and, in the case of not using a forced cooling means such as a cooling medium, it is preferable to provide the cooling chamber 11 at the screen 2c to control the flow of the gas flowing out from the heating furnace 5. A shaft 4 for rotating the turntable 2 is provided under the turntable 2, and the shaft 4 and the turntable 2 are rotated at a predetermined speed by a reduction gear 17 of a driving motor 13 and a belt V. In the present embodiment, in addition to the heating furnace 5 provided on the turntable 2, a preheating chamber 12 for preheating the glove members T and a cooling chamber 11 for cooling the glove members T which have been heated in the heating furnace 5 (see fig. 4) may be provided, but it is also possible to provide only the heating furnace 5 (see fig. 6), or provide the heating furnace 5 and the cooling chamber 11, or provide the heating furnace 5 and the preheating chamber 12. In addition, in the case of the non-fixed preheating chamber 12 and cooling chamber 11, in addition to maintaining a stable temperature in the heating furnace 5 by the inlet/outlet 6 and the shielding screen 2c, a preheating chamber and a cooling chamber may be provided at the inlet/outlet 6.

The shaft 4 for rotating the turntable 2 has a cylindrical or tubular shape having a hollow passage inside, and a gas charging device 9 for feeding the body is connected through a rotary joint 4j (see fig. 2). The gas charging device 9 may use a compressor, a blower, a gas cylinder, etc., and can also charge hot gas. The gas output from the gas filling means 9 is filled into the glove insert Ti of the glove part T via the hollow portion of the glove support part 3. The shaft 4 is connected to the center of the turntable 2, and the fork shaft of the shaft 4 is connected to the coupling part 10 attached to the turntable 2, and the glove support part 3 is fixed by the coupling part 10. The engagement member 10 may be inserted into the glove support 3 by a coupling manner in addition to the coupling with the shaft 4, and the glove support 3 can be freely attached to and detached from the turntable 2 by means of the engagement member 10.

In addition, the engagement member 10 causes the outflow of gas from said axis 4 due to the insertion of the glove support 3 towards the engagement member 10, whereas the valve means blocks the outflow of gas from said axis 4 when the glove support 3 is detached from the engagement member 10. The gas isolation device 7 is a stopcock (valve) or the like, is fixed below the glove support member 3, and controls the outflow of gas. After the stopcock 7 is fixed, when the glove support 3 is detached from the engaging part 10, no gas will flow out of the glove support 3 due to the closure of said stopcock 7.

The glove support 3 provides, in addition to the fixing of the glove part T, an inflation opening for inflating gas into the glove insert Ti, i.e. where the shaft 4 is inserted, and the interior of the glove support 3 is formed with a cylindrical or tubular hollow passage. Thus, the glove support 3 is fixed to the turntable 2 and connected to the shaft 4, and the gas from the gas filling device 9 is filled into the glove insert Ti through the rotary joint 4 j. The inflation opening (fixing opening) of the glove support 3 may be circular or elliptical.

The pressure regulating device 8 on the shaft 4 has a safety valve, the pressure regulating device 8 being used to maintain the pressure in the glove insert Ti at a preset value. The safety valve is capable of venting gas when the pressure exceeds a preset value. If the pressure in the glove insert Ti increases too much due to the heat treatment of the heating furnace 5, the glove exterior material Ts or the glove insert Ti expands excessively, and even when the air pressure is removed, the glove exterior material Ts cannot return to the original shape, which may result in deformation of the glove. Since the glove adjusting means 8 has a safety valve, when the gas pressure in the glove insert Ti exceeds a preset value, the gas is released from the glove insert Ti to prevent the pressure in the glove insert Ti from exceeding a predetermined value. Meanwhile, when inflating the glove insert Ti, it is preferable to use the pressure adjusting means 8 to avoid deformation of the glove exterior material Ts due to excessive inflation of gas.

The glove outer layer material Ts can be selected from materials such as woven cloth, knitted fabric, non-woven material, composite leather, artificial leather, natural leather and plastic film, and can also be selected from materials using fabric as a base material, such as woven cloth covered on plastic film. It can also be selected from chemical fiber fabric such as terylene, nylon, chinlon, acrylic fiber, polyurethane, rayon, vinyl chloride resin, etc., and natural fiber fabric such as resin, cotton, wool, silk, and leather such as hemp, cowhide, etc., and their combination. In addition, regardless of size and shape, the outer layer material Ts of such a glove having five separate fingers is different from a mitten glove, i.e., a glove having one thumb portion and one remaining four finger portion. Patent document 1 cites a prior art which uses a mold of the same size and shape as the glove, and this embodiment does not use such a mold, but swells the glove insert Ti with gas as the mold, so that the shape and size thereof can be flexibly controlled.

As for the glove insert Ti, there is no particular limitation in its material as long as it can be inflated using the gas charging means, however, a preferable material is a waterproof material, and a preferable material is a material having elasticity when the glove is used from the viewpoint of durability and representation. In addition, from the viewpoint of heat preservation and moisture resistance inside the glove, preferable materials are permeable materials such as, specifically, nonporous and porous polyurethane films, elongated porous polytetrafluoroethylene films, polyester films, nylon films, vinyl chloride films, and the like. Further, for example, nonwoven materials, woven fabrics and knitted fabrics, and woven layers covering the film base material, etc. Combinations of two or more materials may also be used. Glove inserts bonded by a fluxing agent or adhesive may also be used, with the edge portions of the insert material (i.e. where the two glove inserts form the shape of the glove) removed, the material removal portions being located at the opening where the glove is donned/doffed.

In addition, in the case of coating the thermoplastic adhesive on the outer side of the glove insert Ti, the glove insert Ti may be made of a glove insert material on which the adhesive is previously coated, or the thermoplastic adhesive may be sprayed on the outer side using an air gun, an air sprayer tool, or the like after the glove insert is made. The adhesive can be applied in a spot, line, block fashion to the surface of the glove insert Ti, or to the entire outer surface of the glove insert without leaving a blank.

In addition, while the glove insert Ti is preferably approximately equal in size to the glove shell material Ts, it may be slightly smaller when the glove insert Ti is elastic; glove inserts larger than the glove shell material Ts may also be used according to the present invention. In this way, the same glove insert Ti can be used for different glove shell materials Ts without regard to changes in shape and size, and therefore without the need to use multiple glove inserts Ti of varying sizes and shapes, thereby reducing costs and simplifying inventory management.

Next, a method of manufacturing a glove embodying the present embodiment of the present invention will be described.

In the present embodiment, the manufacturing method is that the glove insert is adhered to the inner side of the glove exterior material, the glove insert Ti coated with the thermoplastic adhesive on the outer side is inserted to the inner side of the glove exterior material Ts, and the gas is filled into the glove insert Ti by the gas filling means 9 to swell the glove insert Ti, and the glove exterior material Ts is adhered to the glove insert Ti.

The adhesive is coated on the outer surface of the glove insert Ti. Although various adhesives such as thermosetting adhesives, thermoplastic adhesives, photo-curing adhesives, etc. may be selected, the preferred adhesives are thermoplastic adhesives, however, since the plasticity of the adhesive upon heating enables the bonding step to be performed easily at any time. In the present embodiment, a thermoplastic adhesive is a preferred adhesive due to the hot air charged into the glove insert Ti by the heating furnace 5 and the gas charging device 9. Thermoplastic adhesives, also known as hot melt adhesives, are solid adhesives at ambient temperature, and soften and melt when heated. A thermoplastic adhesive is applied to the glove insert Ti and then heated to bond it to the glove shell material Ts, the thermoplastic adhesive softens or melts and the bonding is achieved by subsequent cooling. The thermoplastic adhesive can be applied without leaving a space over the entire outer surface of the glove insert Ti, or it can be applied in the form of dots, lines or blocks. Dot-coating is preferred from the standpoint of permeability and handling of the glove member, but coating the entire surface without leaving a margin is the most preferred from the standpoint of adhesive strength.

Any of the well-known thermoplastic adhesives may be selected and the softening point selected as desired depending on the material of the glove shell Ts and the glove insert Ti, however, 60 ℃ to 180 ℃ is the preferred softening point temperature range from an adhesion standpoint.

On the glove support member 3, a thermoplastic adhesive coated on the glove insert Ti in the post-insertion state on the inner side of the glove skin material Ts is fixed on the glove member T by contact. The opening in the glove insert Ti of the glove part T matches the shape of the outer edge of the glove support 3 in such a way that the glove part T is secured to the glove support 3. The glove member T may be fixed to the glove support member 3 using a tool such as a strap, a belt, or a clip. However, when the fixing is performed by using the above components, the air leakage phenomenon is obvious after the air is filled. And the glove part T is fixed on the glove supporting part 3 by adopting an elastic part or rubber and the like and combining a binding belt, so that the air leakage phenomenon can be well reduced.

Next, gas is filled into the glove insert Ti by the gas filling means 9 to expand the glove insert Ti, so that the glove exterior material Ts and the glove insert Ti are tightly bonded. The gas to be charged may be air, nitrogen, carbon dioxide, helium, etc., and preferably air for cost reasons. Further, the temperature of the gas may be room temperature, but if the gas is charged while being heated to 50 ℃ to 90 ℃, the thermoplastic adhesive is rapidly softened or melted, which is a preferable mode from the viewpoint of improving productivity. The gas pressure of the gas filled in the glove insert Ti is preferably 0.01-0.5kg/cm2(1.0-49 kPa). When the air pressure is lower than 0.01kg/cm2(1.0kPa), the glove insert Ti may not be sufficiently adhered to the glove exterior material Ts, and when the air pressure is higher than 0.5kg/cm2(49kPa), the glove exterior material Ts may be elongated and may not be restored to its original shape. In addition, a restraining control cover 15 may be used if necessary to avoid excessive elongation of the glove skin material Ts (see fig. 7).

Before the glove insert Ti is inserted into the glove skin material Ts and the gas is filled into the glove insert Ti, the fingertip portions are preheated to 80 to 200 ℃ using a tool such as a cylindrical iron, the fingertip portions of the glove insert Ti and the fingertip portions of the glove skin material Ts are preliminarily bonded, and the fingertip portions of the glove insert Ti and the glove skin material Ts are fixed together, which is advantageous for the firmness of the bonding. In addition, for the fingers and the base of the fingers, before the glove insert Ti is inserted into the glove skin material Ts in the same manner and the gas is injected into the glove insert Ti, these portions are heated to 80 ℃ to 200 ℃ using a tool such as a cylindrical iron, to preliminarily bond the base of the fingers of the glove insert Ti and the base of the fingers of the glove skin material Ts, and to fix the base of the fingers of the glove insert Ti and the glove skin material Ts together, thereby contributing to the firmness of the bonding.

Heating is then carried out. The turntable 2 rotates to send the glove T to the heating furnace 5, and heating is started. The glove shell material Ts and the glove insert Ti are in an adhesive state and the thermoplastic adhesive on the outside of the glove insert Ti softens or melts. The degree of heat treatment of the heating furnace 5 can be arbitrarily set according to the material Ts of the glove skin and the material Ti of the glove insert and the softening point of the thermoplastic adhesive, however, it is preferable to perform the heat treatment operation in the temperature range of 60 ℃ to 200 ℃. If the heat treatment is such that the gas pressure inside the glove insert Ti is raised, particularly when the glove exterior material Ts is a thin material that is easily deformed, it is preferable to exhaust the gas through the pressure adjusting means 8 from the viewpoint of maintaining the shape of the glove part T, in order to prevent the gas pressure in the glove insert Ti from exceeding a certain value. In addition, a restraining control cover 15 may be used as necessary to avoid elongation of the glove exterior material Ts (see fig. 7).

Depending on the material of the glove shell Ts and the glove insert Ti, the softening point of the thermoplastic adhesive applied to the glove insert Ti and the degree of heat treatment, the duration of the heat treatment is preferably from 10 seconds to 10 minutes. From the viewpoint of the fastness of bonding and the productivity of the glove finished product, the preferable time is 1 minute to 5 minutes. If the heat treatment time is less than 10 seconds, the glove exterior material Ts and the glove insert Ti may not be sufficiently bonded, and if the heat treatment time exceeds 10 minutes, productivity may be lowered. The glove members T may be preheated in the preheating chamber 12 before being heated in the heating furnace 5.

After the heating treatment is performed for a predetermined time in the heating furnace 5, cooling is performed by a cooling device provided in a cooling chamber 11 following the heating furnace 5 (see fig. 4). This cooling is performed in a state after the gas is filled into the glove insert Ti through the gas filling means 9. After the heat treatment in the heating furnace 5 for a predetermined time, the glove member T having the glove insert Ti inserted into the glove skin material Ts is taken out and sent to the inlet/outlet 6, and the thermoplastic adhesive is preferably allowed to cool naturally.

In this case, when the glove part T is removed from the fixed heating furnace 5 and the stopcock 7 (gas isolation means) of the glove support part 3 is closed, the glove support part 3 is removed from the turntable 2 at the inlet/outlet 6, the gas charged into the glove insert Ti by the gas charging means 9 is cooled in the charged state, and the thermoplastic adhesive softened by heating also starts to be cooled. When the cooling is over, the gas in the glove insert Ti can be removed since the thermoplastic resin has hardened, and for this reason the adhesion of the glove insert Ti to the glove skin material Ts is stronger for the glove part T to be detached from the glove support part 3.

Alternatively, the glove insert Ti may be cooled after removing the gas from it. However, the cooling is preferably performed in a state where the gas is filled into the glove insert Ti. Immediately after leaving the heating furnace 5, the thermoplastic adhesive cannot be sufficiently hardened, and if the glove support member (the glove support member without the gas isolation device 7, or the glove support member with the gas isolation device 7 not closed) is directly removed from the turntable 2 after leaving the heating furnace 5 and the glove member T is left from the glove support member 3, the gas in the glove insert Ti is removed, so that the glove insert Ti may be partially detached from the glove skin material Ts due to a sudden change in pressure in the glove member T. Since the gas-barrier means 7 mounted on the glove support 3 can prevent the outflow of gas, a firm adhesion between the glove insert Ti and the glove skin material Ts can be achieved. In this way, the thermoplastic adhesive is hardened and the glove insert Ti of the glove member T produced is bonded to the inside of the glove skin material Ts.

In addition, while the pressure in the heating furnace is increased by filling the gas into the glove insert Ti in the manner described, a method is used to prevent the deformation of the glove exterior material Ts when the pressure in the glove insert Ti is excessively high, i.e., to avoid the excessive elongation of the glove exterior material Ts with the restraining control cover 15 (see fig. 7). If the glove shell material Ts is stretched and the glove insert Ti returns to its original size, the suppression control cage 15 is preferably approximately the same size as the glove and the suppression control cage 15 may also be larger than the glove shell material Ts. The cover suppression control cover 15 is preferably provided with 5 fingers, but may not have all 5 fingers in order to prevent elongation of the glove covering material Ts.

Second embodiment of the present invention

Figures 5 and 6 illustrate a second embodiment of the invention in which a configuration is used in which a suction device 16 is connected to the shaft 4 for removing gas from the glove insert Ti. In particular, if not air but nitrogen gas, helium gas, etc. are filled in the glove insert Ti, when air is sucked out from the inside of the glove insert Ti, nitrogen gas, helium gas, etc. are simultaneously filled. For this type of glove support 3 and shaft 4, only one tube may be used, but it is more appropriate to use 2 to 3 tubes, each of which is separate when filling and removing gas (air). In the present embodiment, the cooling chamber 11 and the preheating chamber 12 used in the first embodiment of the present invention are not used, and the glove support members 3 in the present embodiment are provided on the inner side and the outer side in the rotating direction of the turntable 2, and the number of the glove support members 3 may be larger than that in the first embodiment.

In addition, in the first and second embodiments of the present invention, instead of the turn table 2, a loop type conveyor belt may be used, in which the glove support members 3 are fixed, and when the conveyor belt is rotated, the glove support members 3 enter the heating furnace 5, are subjected to a heating process for a predetermined time, and then the glove support members 3 are returned to the entrance/exit. In this case, the glove support section 3 has a plurality of branches respectively connected to the plurality of glove support sections 3, unlike the one central shaft 4 in the first embodiment, but one glove support section is connected to one shaft 4, so that the support and rotation of the plurality of glove sections T can be simultaneously and integrally performed.

Third embodiment of the present invention

The present embodiment shown in fig. 8 is an apparatus in which the base has an engaging part 10, the gas filling means 9 is connected to the engaging part 10, the glove support part 3 is fixed to the engaging part 10, and gas such as air is filled into the glove insert by the gas filling means 9, and a heating furnace is provided to perform a special heat treatment. That is, the means for inflating gas into the glove insert Ti and the means for heat treatment (heating furnace) are separate, and the gas isolation means 7 confines gas into the glove insert Ti after the gas is inflated into the glove insert Ti. Next, the glove support member 3 is detached from the joining member 10, the glove support member 3 is moved to a heating furnace, and the glove member T is heat-treated so that the glove insert Ti and the glove skin material Ts are bonded together by the thermoplastic adhesive. In the present embodiment, although a device for conveying the supporting member 3, such as a turntable, is not used, the pressure adjusting device 8 is provided. Further, it is also preferable to dispose the air suction device 16.

The glove is produced by applying a thermoplastic adhesive to the outside of a glove insert Ti, inserting the same into the inside of a glove exterior material Ts to produce a glove member T, and fixing the glove member T to a glove support member 3. Next, the glove support member 3 is fixed to the joint member 10, and the gas is filled into the glove insert Ti, and the glove insert Ti is inflated to bond the glove exterior material Ts and the glove insert Ti together. At this time, as in the first and second embodiments, the thermoplastic adhesive coated on the outside of the glove insert Ti is present between the glove insert Ti and the glove exterior material Ts, and is bonded to the glove exterior material Ts. Next, the gas isolation means 7 of the glove support 3 are closed, confining the gas inside the glove insert Ti. The gas pressure of the inflation gas is the same as in the first and second embodiments. In addition, the glove exterior material Ts and the glove insert Ti, the thermoplastic adhesive, the finger tip and the finger base of the glove insert Ti and the glove exterior material Ts, and the like are pre-bonded, all as in the first and second embodiments.

Subsequently, the glove support members 3 supporting the glove members T are removed from the joining member 10, and are introduced into a heating furnace for heat treatment. Upon heat treatment, the adhesive (thermoplastic adhesive) softens or melts and the glove skin material Ts adheres to the glove insert Ti. Subsequently, cooling is performed to complete the bonding operation of the glove skin material Ts to the glove insert Ti. The temperature and duration of the heat treatment are the same as in the first and second embodiments of the present invention.

When the oven is used as an accessory to a conveyor such as a carousel 2 or conveyor, the glove support members 3 for holding the glove members T on the conveyor are preferably stationary and subsequently heat treated. In addition, if a heating furnace without a transfer means such as a turntable is used, the glove support members 3 for holding the glove members T are introduced into the heating furnace to be heat-treated, and after a necessary time has elapsed, the glove support members 3 for holding the glove members T are preferably removed from the heating furnace. For the cooling to be performed after the heat treatment, although the gas in the glove insert Ti may be removed, it is preferable to perform the cooling in a state where the gas is filled in the glove insert Ti, in view of the firmness of the bonding, that is, in the same manner as the first and second embodiments of the present invention.

Fourth embodiment of the present invention

In order to bond the glove insert Ti to the glove skin material Ts, gas is introduced into the glove insert Ti and heat treated; as for the type of glove skin material Ts, the glove skin material Ts is deformed (expanded) by the pressure of the inflating gas, and cannot be restored to its original shape after the gas in the insert is removed. The present embodiment relates to a method and apparatus for manufacturing a glove, wherein the deformation of the glove shell material Ts is controllable when the glove insert Ti is bonded to the glove shell material Ts.

The glove manufacturing method of this embodiment is the same as the first embodiment of the present invention, the glove insert Ti is adhered to the inner side of the glove exterior material Ts, and, when the glove insert Ti coated with the thermoplastic adhesive on the outer side is inserted to the inner side of the glove exterior material Ts, the gas is filled into the glove insert Ti by the gas filling means 9 to swell the glove insert Ti, so that the glove exterior material Ts is adhered to the glove insert Ti, but further pressure is applied to the glove insert Ti during the heat treatment, and the pressure in the glove insert is increased as compared with the initial stage of the heat treatment.

In this way, when the glove exterior material Ts which is easily deformed is used, it is possible to control productivity in order to control deformation of the glove exterior material and reduce defective products without using a control cover after bonding the glove insert Ti. In addition, since sufficient pressure can be applied to the inside of the glove insert Ti to firmly adhere the glove insert Ti and the glove exterior material Ts, it is possible to manufacture a glove in which instability in adhesion of the glove insert Ti and the glove exterior material Ts is controlled.

The glove exterior material Ts, glove insert Ti, thermoplastic adhesive, and the like of the present embodiment can be used in the same manner as the first embodiment.

Further, it is preferable to perform the insertion of the glove insert Ti onto the glove exterior material Ts in the same manner as in the first embodiment, and it is preferable to pre-bond the base of the fingers of the glove insert Ti with the base of the fingers of the glove exterior material Ts and pre-bond the fingertip portions of the glove insert Ti with the fingertip portions of the glove exterior material Ts in the same manner as in the first embodiment.

As for the conditions of the heat treatment, the pressure in the glove insert Ti is low in the initial stage of the heat treatment, at which time the glove skin material Ts is not excessively elongated. The low pressure during the heat treatment varies depending on the kind of the glove covering material Ts, but is suitably more than 0.0001MPa (0.001kg/cm2), preferably more than 0.0005MPa (0.005kg/cm 2). Further, it is preferably less than 0.003MPa (0.03kg/cm 2). If the air pressure is less than 0.0001MPa (0.001kg/cm2), a gap may be formed between the glove exterior material Ts and the glove insert Ti, after which the glove exterior material Ts and the glove insert Ti are not sufficiently bonded when pressure is applied, and thus, a gap may be formed at a portion where bonding is insufficient, and sufficient bonding strength may not be obtained finally.

Further, if the pressure exceeds 0.003MPa, the glove exterior material Ts may be deformed.

In the heat treatment, after further pressure is applied to the glove insert Ti, the amount of pressure therein depends on the kind of glove shell material Ts, but is preferably less than 0.05 MPa. More preferably, the pressure is greater than 0.003MPa (0.03kg/cm2) and less than 0.01MPa (0.1kg/cm 2).

If the pressure exceeds 0.05MPa (0.5kg/cm2), the glove skin material Ts may elongate and fail to return to its original shape.

Although heating may be performed in accordance with the heating degree and the heating time in the first embodiment, in the present embodiment, further pressure is applied at the time of heat treatment. The pressure is applied for a time of less than 20 seconds from immediately before the end of the heat treatment, and the treatment is preferably performed at a high pressure for 3 to 20 seconds. Next, the pressure in the glove insert Ti is preferably returned to the low pressure of the initial stage of the heat treatment, and then cooled.

As for the cooling, it is also suitable to perform in the same manner as the first embodiment.

Next, the apparatus used in the present embodiment will be explained. Fig. 9 and 10 are schematic views of the present embodiment, describing how the heat treatment is performed when 6 glove members T are attached, however, this number does not constitute a limitation on the number of attachments.

The glove manufacturing apparatus according to the present embodiment includes the same turntable 2, heating device 5, glove support member 3, gas isolation device 7, joining member 10, and the like as those of the first embodiment.

In the present embodiment, as shown in fig. 9 and 10, in order to change the air pressure of each of the plurality of glove inserts Ti when the glove member T is heat-treated, there are provided the following means: the detection means on the shaft 4, i.e. the detection bolt 21; an abutment switch 22 for issuing a switching command to a pressure switching device that detects the detection bolt 21; an electropneumatic on-off valve 20, i.e. pressure switching means, for switching the pressure provided into each glove insert Ti; a high-pressure adjusting device 8a for supplying high pressure to the electropneumatic switching valve 20; a low-pressure regulating device 8b for supplying a low pressure to the electropneumatic switching valve 20 in the same manner; a gas filling device 9 for filling gas into the glove insert Ti is also connected to the pressure regulating devices of the high-pressure regulating device 8a and the low-pressure regulating device 8 b.

In addition, an electropneumatic on-off valve 20 is connected to the rotary joint 4j, and gas is fed into the glove insert Ti by connecting hoses through the rotary joint 4j to the rotary table 2, the joint part 10 on the rotary table 2, the glove support part 3, and the glove part T.

Also, the present embodiment has 6 electropneumatic on-off valves 20 to fix 6 glove support members. Further, in the same manner, there are also 6 detection bolts 21, an abutment switch 22, pressure adjusting means (for high pressure and low pressure, respectively), and the joint member 10, and the like. In addition, there are 6 connection ports on the rotary joint 4j for charging and removing gas, each connected to an electropneumatic switching valve 20 and the joint part 10 on the rotary disk 2.

Further, by using the apparatus of fig. 9, when the glove support part 3 is fixed to the joint part 10, low-pressure gas is filled in the glove insert Ti, and thereafter, pressure is applied for a preset time in the heat treatment, so that the pressure in the glove insert is increased; however, as shown in fig. 8, which is described in the third embodiment, especially when the glove support members 3 are fixed to the joint member 10, gas such as air from the gas filling means 9 is filled into the glove inserts, and a plurality of glove support members 3 are provided with a plurality of glove members T into which glove inserts Ti of the glove members T are filled with low-pressure gas (after filling the gas, the gas isolation means 7 is closed to prevent the outflow of the gas in the glove inserts Ti); as shown in the apparatus of fig. 9 of the present embodiment, a plurality of glove support members 3 are provided fixed to the joint member 10, the gas-isolating means is opened, the heat treatment is performed, and further pressure is applied to the glove insert Ti during the heat treatment, the pressure in the glove insert is increased as compared with the initial stage of the heat treatment, and thus, the glove insert Ti and the glove exterior material Ts can be bonded together.

Examples

Example 1

The outer layer material Ts of the ski glove is made of polyester fabric, a thermoplastic adhesive (softening point 85 ℃ C.) is coated on the glove insert Ti, and is applied in a dotted manner on one side of a hand-shaped non-porous film made of permeable waterproof polyurethane resin, and both of these hand-shaped articles coated with the thermoplastic adhesive are covered on the outer surface of the glove insert, and the outer edge portion except the opening of the glove is adhered. The glove insert Ti is inserted such that the thermoplastic adhesive on the glove insert Ti adheres to the inside of the glove shell material Ts to form the glove part T. The glove insert Ti is larger in size than the glove shell material Ts. The glove manufacturing apparatus used was the apparatus in the first embodiment of the present invention. Due to the insertion of the glove support 3 into the engaging member 10 and the outflow of gas from the shaft 4, the engaging member 10 having a valve mechanism is used to prevent the outflow of gas from the shaft 4 when the glove support 3 is removed from the engaging member 10.

Next, the fingertips and finger base portions of the glove insert Ti were pre-bonded to the fingertips and finger base portions, respectively, of the glove shell material Ts using a cylindrical iron heated to 100 ℃ to soften the thermoplastic adhesive of the fingertips and finger base portions.

Next, after the glove part T is fixed to the glove support part 3 removed from the turn plate 2 (fixed with a strap), the glove support part 3 is fixed to the turn plate 2 by the joint part 10, and the gas is filled into the glove insert Ti from the gas device 9 attached to the glove support part 3, causing the glove insert Ti to swell. At this time, the air pressure in the glove insert Ti was 0.2kg/cm2(19.6 kPa). The rotary table 2 is rotated, and the glove members T are introduced into the heating furnace 5 and heat-treated at 120 ℃ for 2 minutes. After 3 minutes (preheating for 30 seconds, heating for 2 minutes, cooling for 30 seconds), the glove part T is fed to the inlet/outlet port, and after the stopcock (gas isolation means 7) is closed, the glove part T is removed together with the glove support member 3, thus producing the glove part T in which the glove insert Ti is bonded to the glove skin material Ts with a thermoplastic adhesive.

Further, the glove support members 3, which have been just removed and to which the glove members T have been fixed, are immediately fixed and inflated, so that it is expected that the glove members T manufactured as planned are obtained. The glove part T thus produced has the entire glove exterior material Ts, and the glove insert Ti is firmly bonded with high productivity. In addition, in the present embodiment, since the cooling treatment is performed in the cooling chamber (50-60 ℃), if the glove part T sent to the inlet/outlet 6 is removed together with the glove support part 3 with the stopcock (gas isolation means) 7 in the closed state, the thermoplastic adhesive is cooled and hardened, and the entire glove insert Ti is sufficiently and firmly bonded to the glove exterior material Ts, and no bonding instability occurs.

Example 2

After the gas (hot gas) having a temperature of 60-80 ℃ is filled into the glove insert Ti via the glove support 3, it is transferred to the heating furnace 5 by the turntable 2 and heated at 120 ℃ for 2 minutes. Meanwhile, the cooling duration was 24 seconds. The screen 2c between the heating furnace 5 and the preheating chamber 12 is removed and preheating is not performed in the preheating chamber 12 and the heating furnace 5. Otherwise, the rest of the method is the same as in example 1.

The glove part T obtained by this method is sufficiently firmly bonded to the glove insert Ti by the glove skin material Ts, and is free from unstable bonding. In addition, in comparative example 1, when hot gas was charged into the preheating chamber, the process was accelerated. This is because the introduction of hot air rapidly softens or melts the thermoplastic adhesive on the outside.

Example 3

The glove manufacturing apparatus in the second embodiment is equipped with only the heating furnace 5 without using the preheating chamber 12 and the cooling chamber 11, and after the heat treatment (the heat treatment duration is 2 minutes 30 seconds), the glove part T is sent to the inlet/outlet 6, the stopcock (gas isolation means) is closed, the glove part T is taken off together with the glove support part 3, and natural cooling is performed at room temperature for 10 minutes. Except for this, the rest of the process was the same as in example 1, thus producing glove part T. The glove part T obtained in this manner had a sufficiently strong adhesion between the glove skin material Ts and the glove insert Ti, and no adhesion instability occurred. And, the productivity is higher than that when using the existing mold.

Example 4

The glove manufacturing apparatus in the second embodiment of the present invention does not use the preheating chamber 12 and the cooling chamber 11, only the heating furnace 5 is provided, and after the air is removed from the glove insert Ti by the suction device 16, the nitrogen gas is charged therein. Then, after the heat treatment (the heat treatment duration was 2 minutes 30 seconds), the stopcocks (gas isolation means) of the glove part T reaching the inlet/outlet 6 were closed, and the glove part T was taken off together with the glove support 3, followed by natural cooling at room temperature for 10 minutes. Except for this, the rest of the process was the same as in example 1, thus producing glove part T. The glove part T obtained in this manner had a sufficiently strong adhesion between the glove skin material Ts and the glove insert Ti, and no adhesion instability occurred. And, the productivity is higher than that when using the existing mold.

Example 5

The glove insert Ti coated with the thermoplastic adhesive on the outer side is inserted into a glove member T, which is wound around the glove support member 3 with a silicon tape and is firmly fixed with a binding tape, to be bonded to the inner side of the glove exterior material Ts. The glove support member 3 is fixed to the joining member 10 of the third embodiment without heating furnace and connected to the gas filling means 9, and air is filled into the glove insert Ti to expand it and bond the glove insert Ti and the glove skin material Ts.

In addition, as in example 1, the valve mechanism of the engagement member 10 prevents the outflow of gas from the gas-filling device after the glove support member 3 is removed from the engagement member 10.

Next, the gas-isolating means 7 of the glove support 3 are closed, trapping air in the glove insert Ti. The glove support unit is detached from the joining member 10, and the glove support unit 3 is moved to a separate heating furnace and heat-treated for 2 minutes.

Next, the glove support 3 was removed from the heating furnace and allowed to cool naturally at room temperature for 10 minutes. After cooling, the glove member T is removed from the glove support member 3, and then, after confirming the bonded state, the glove exterior material Ts and the glove insert Ti are bonded sufficiently and firmly without leaving a gap. However, since the gas charging device 9 and the heating device are separated, the yield of the product in this embodiment is lower than that in the other embodiments.

In addition, the glove exterior material Ts, glove insert Ti, thermoplastic adhesive, heat treatment temperature, air pressure inside the glove insert Ti, and adhesion of the fingertip and base portion of the glove insert Ti to the fingertip and base portion of the glove exterior material Ts were the same as in example 1.

Although in each of the above embodiments the glove member T is manufactured by adhering the glove insert Ti to the inside of the glove exterior material Ts, the glove may be manufactured by fixing the interior insert material to the glove member T by other known methods.

Example 6

This example used the glove manufacturing method of the fourth embodiment.

The glove outer layer material Ts is a material used in golf game and is made of a material having a vinyl chloride resin film layer on one side. The glove insert Ti is a hand-shaped non-porous film made of, for example, permeable waterproof urethane resin, and two such thermoplastic adhesive-coated hands are covered on the outer surface of the glove insert, and the remaining outer edge portions except for the glove opening are bonded to make the glove insert. Next, a powdered thermoplastic adhesive (softening point of 75 ℃) was sprinkled over the entire outer surface of the glove insert to obtain a glove insert coated on the outside with the thermoplastic adhesive.

The glove insert Ti is inserted so that the thermoplastic adhesive on the glove insert Ti adheres to the inside of the glove skin material Ts to form the glove part T. A glove insert Ti larger than the glove skin material Ts is used.

Next, the finger tips and finger root portions of the glove insert Ti are pre-bonded to the finger tips and finger root portions of the glove shell material Ts by softening the thermoplastic adhesive in the finger tips and finger root portions with a cylindrical iron heated to 100 ℃.

Subsequently, the glove member T is fixed to the glove support member 3. The glove members T and the wrist portions of the glove support members 3 are wrapped with rubber bands, which are fixed thereto using clips.

The gas isolation means 7 on the glove support 3 to which the glove member T is secured is closed and the glove support 3 is secured to the engagement part 10 of the apparatus shown in figure 8 of the third embodiment of the present invention, and air is inflated into the glove insert Ti. The gas pressure in the glove insert Ti at this time was 0.001MPa (0.01kg/cm 2). To repeat this operation, a plurality of glove support members 3 are used, glove members T being secured to the glove support members 3, and air being inflated into glove inserts Ti. Further, when the glove support unit 3 is removed from the engaging member 10, as shown in embodiment 1, the valve mechanism of the engaging member 10 of fig. 8 can prevent the outflow of gas from the gas inflator.

Next, the gas isolation means of the glove support 3 is closed, the glove support 3 is removed from the apparatus of the third embodiment shown in fig. 8, secured to the engagement means 10 on the turntable 2 of the glove manufacturing apparatus of the fourth embodiment shown in fig. 9, and the gas isolation means 7 on the glove support 3 is opened. The glove support part 3 is connected to a pressure adjusting means for low pressure 8b, 6 rotary joints 4j and an electro-pneumatic switching valve 20 through a heat-resistant hose passing through the hollow shaft 4, and the pressure adjusting means for low pressure 8b is connected to the gas charging means 9. The pressure was adjusted to 0.001MPa (0.01kg/cm2) by a pressure adjusting device for low pressure. In addition, the engagement member 10 has a valve mechanism to prevent the outflow of gas from the gas inflator.

The turntable 2 rotates at a predetermined speed, and the glove part T is conveyed to a heating furnace 5 (heated using a circulation type hot air heater) at a heat treatment temperature of 120 ℃ (120 seconds). 8 seconds before the end of the heat treatment, the pressure inside the glove insert was set to 0.005MPa (0.05kg/cm2) by switching from the low-pressure regulator 8b to the high-pressure regulator 8a through the electropneumatic on-off valve 20, and the heat treatment was continued for 6 seconds. 2 seconds before the end of the heat treatment (at which time the glove support member is moved to the inlet/outlet), the pressure in the glove insert is restored to the initial value of 0.001MPa (0.01kg/cm2) by switching from the high-pressure regulating device 8a to the low-pressure regulating device 8 b. Figure 11 illustrates the pressure profile in the glove insert during heat treatment.

When the low-pressure regulator 8b is switched to the high-pressure regulator 8a, the detection bolt 21 fixed to the shaft 4 is detected by the adjacent switch 22, and a switching command is issued to the electropneumatic switching valve. Referring to the reverse process, after 6 seconds of switching to the high-pressure regulator, the electropneumatic switching valve receives a command to switch it to the low-pressure regulator 8 b.

After the heat treatment is completed, the glove support 3 is moved to the inlet/outlet port, the gas isolation device 7 is closed, and the glove support 3 and the glove member T are removed from the engaging member 10 on the turntable 2, wherein the gas has been filled into the glove insert Ti and the cooling is performed at room temperature for 20 seconds. Thereafter, the glove member T is removed from the glove support member 3. Immediately, the glove support members 3 are fixed to these joining members 10, and the gas barrier 7 is opened to continue the heat treatment. In which the glove support 3 has a glove part T thereon and the glove insert Ti is previously inflated with gas by the apparatus of figure 8.

The glove exterior material Ts after cooling and the glove insert Ti of the glove member T are sufficiently and firmly bonded, so that the glove member T obtained without deformation such as elongation is obtained.

In addition, with respect to the glove part T composed of the glove exterior material Ts and the glove insert Ti obtained in the same manner, at an air pressure of 0.005MPa (0.05kg/cm2) in the glove insert Ti, if the heat treatment is continued for 120 seconds, the glove exterior material Ts will be excessively elongated, and will be still larger than the initial size even after the air in the glove insert Ti is removed.

In addition, in the present example, the glove manufacturing apparatus shown in fig. 8 of the third embodiment was used, the glove member T having the gas-filled glove insert Ti fixed to the glove support member 3 was prepared and used in advance, and after the heat treatment was performed using the apparatus of fig. 9 of the fourth embodiment, the productivity was improved compared to the previous examples.

Further, in the present embodiment, the apparatus of fig. 8 is used, and although the glove member T having the gas-filled glove insert Ti fixed to the glove support member 3 is prepared and used in advance, if the method of the fourth embodiment is used, if the apparatus of fig. 8 is not prepared in advance and only the apparatus of fig. 9 is used to bond the glove insert Ti and the glove exterior material Ts together, it goes without saying that due to the elongation of the prepared glove exterior material Ts, it is possible to control the generation of defective products and achieve a firm bonding between the glove insert Ti and the glove exterior material Ts.

Industrial applications

According to the invention, the glove insert is inflated by the inflation gas, the glove insert is bonded to the glove shell material, and the adhesive is provided by being interposed between the glove shell material and the glove insert. Thus, the deformation of the bond can be controlled by simply inflating the glove insert with gas to produce a suitably shaped glove. Further, the gas filling is performed by a relatively simple apparatus, and the thermoplastic adhesive is softened and melted by feeding the glove part with the glove insert inserted therein to the glove exterior material to the heating furnace provided at a predetermined position on the rotating disk by using the rotating disk, which can anticipate an improvement in the work efficiency of the bonding operation for inserting the glove insert into the inside of the glove exterior material, and thus achieve an improvement in productivity.
