Method and apparatus for attaching buttons Field of application of the invention

The present invention relates to a method of attaching buttons to a textile material. The button consists of a plastic material and is composed as follows: From a main body which serves to be attached to one side of the textile material to v / earth, and from a protruding part, which at least partially passes through the textile material and on the opposite side of the textile material relative to the side on which the main body of the button is attached, is deformed to a deformation head. The present invention also relates to an apparatus for carrying out the method.

Characteristic of the known technical solutions

The known method for attaching buttons, hooks, eyelets and similar accessories to fabrics or possibly to plastic films by sewing has many obvious disadvantages. Sewing is therefore relatively complicated and, in the context of modern mass production, requires almost unacceptably long working times. Even when sewing by hand, attaching buttons is tedious and time-consuming work. On the other hand, numerous attempts have been made to find other ways of attaching buttons and similar accessories than by sewing. Consequently, it is known to manufacture the candidate button or accessory in two parts which are joined by means of a die passing through the fabric. A button of this type has been described, for example, in US Pat. No. 3,360,835.

However, in the context of buttons of this type, it is complicated to obtain a rational and simple operation due to the difficulty of positioning the two parts of the button in the correct position relative to each other on the two sides of the fabric. The devices that hold the two parts together are also at a disadvantage, resulting in high manufacturing costs and a limitation in size and pattern. Knobs and accessories of this known design have therefore experienced only limited use in the clothing industry and this only in connection with heavy clothing, such as work clothing.

In order to get a simpler and smaller button, it has been proposed as an alternative to provide a knob of plastic material with a protruding part in the form of a shaft. This shaft then serves to be passed through the fabric and subsequently deformed into a head (see, for example, CH-PS 411 427 and GB-PS 1 229 119). As a method for deformation of the above part, deformation by means of heat and mechanical pressure has been successively proposed. However, if these methods of deformation are used, certain difficulties arise. In connection with a deformation by heat there is thus a risk of overheating and, consequently, there is a melting or transformation of the plastic material, so that there are separation fractures. Moreover, when plastic material melts there is a risk that it will adhere to the deformation tool and the head that should be deformed will remain incomplete. Mechanical deformation can cause the plastic material to be crushed so that the rivet head will be incomplete. It is also known

- 3 - Berlin, d.I5.1.1980 56 245 26

that the "memory" of the plastic materials can lead to the plastic part at least partially after some time its original shape again.

It can also be seen from said British patent that measures have been taken to clamp the textile material in a groove, whereby one is not limited to rely only on the contact surface of the deformation head, but also obtains some attachment by friction. However, attachment by friction has also proved to be questionable reliability, especially after the garment has been used and worn for some time. This has resulted in the threads being worn or displaced around the hole due to the movements between the button and the fabric. Another disadvantage associated with buttons with a free deformation head is that something is missing which prevents the neck from being forced into the textile material, which can cause difficulties in connection with the buttoning. Therefore, one must provide for a particular type of spacer element, which according to the British patent includes an approach. However, this necessitates the necessity of dimensioning the neck with a large cross-section, which causes a not so safe and, moreover, unpleasant buttoning, since the fabric will curl around the buttonhole around the other neck.

Most apparel articles are provided with a series of buttons which are in a particular arrangement, for example in connection with shirts in a long row. They serve, with a part of the garment, which with buttonholes in a corresponding

- 4 - Berlin, d.15.1.1980 56 245 26

Arrangement is equipped »to be buttoned. In this context, the term "buttonholes" includes not only slots in the fabric material, but e.g. As well as loops or slings that protrude from a hem.

Such a buttonhole arrangement for buttoning represents a significant portion of the price of the garment because of the labor involved. In fact, the work required, in addition to the buttonholes, involves the attachment of the buttons in certain positions in a particular arrangement and the buttoning of the garment, for many reasons garments are usually delivered in the buttoned state.

Aim of the invention;

The aim of the invention is to improve the attachment of buttons or similar accessories to textile material so that under the conditions of economical mass production increased durability of the connection between the button and textile material is achieved.

Explanation of the essence of the invention

The object of the present invention is to provide a method by which a button or similar accessory, which may be present as an individual part, can be attached to a textile material or to a film after the button in question or the like Accessory with one side of the textile material or the film has been brought into contact with a protruding part or shaft. This previous part or

- 5 - Berlin, d.15.1.1980 56 245 26

Shank is deformed. This method is not intended to have the disadvantages that are associated with the described known methods.

It is also an object of the present invention to provide an apparatus for attaching buttons to garments in groups in a particular arrangement and in such a manner that the respective buttons assume a buttoned position after installation, without any particular need for buttoning after attaching the buttons.

Another object of the present invention is to provide a button or corresponding accessory which has a presentation well suited to this article to be used in conjunction with the method of the invention.

The objects of the present invention are realized by the formation of the deformation head with the aid of a tool which is subjected to vibrations in the ultrasonic range. In this case, the tool is pressed against the end of the protruding part or shaft of the knob in such a manner that the material of the shaft merges by flowing into the deformation head. A smooth profile without any sharp cross-sectional changes and with a rounded transition to the main body of the button is formed on the protruding part at least in the inner region thereof in a position between the formed deformation head and the main body of the button.

-6 - Berlin, d.15.1.1980

56 245 26

As a way of achieving the deformation of the protruding part of the knob, ultrasonic treatment is proposed in the context of the present invention. The ultrasound has previously been used to join plastic parts together. On the material which is exposed to the ultrasonic vibrations, a fusion of the surfaces of the material is achieved with each other. However, it has been found that a deformation in the sense of splitting the material to obtain another shape by pressing a vibrating tool against a plastic body can be achieved. This machining process does not include the risks involved in melting and gluing. On the other hand, if the process is not carried out in the correct manner, there is a risk that the material will be converted in such a way that cracks will form. However, if the ultrasonic treatment is carried out correctly, it will give an excellent result with good deformation of the material without any risk of the material returning to its original shape.

The method basically states that the button or any other suitable accessory must be provided with a protruding part or shaft that is partially extended through the textile material, after which the tip of the protruding part or shaft on the other side of the textile material is deformed. This is done by pressing the tool against the tip of the inserted part at the same instant that the main body of the knob or other accessory is counter-pressure of a comparatively large amount

- 7 - Berlin, d.15.1.1980 55 245 26

Surface is subjected to adaptation to the shape of the present button. The tool consists of steel or another hard material. The tool end is shaped according to the desired shape of the deformation head. During pressing, the tool is subject to ultrasonic vibrations in the frequency range of 18000 ЗОООО Hz. The surface against which the main body of the knob or other accessory abuts must have said shape, whereby a large contact surface must be ensured, otherwise there is a risk is that the main body passes through the ultrasonic vibrations to deformation. The said surface for the back pressure must be made of a material which is not deformed or does not adhere to the button. Also, in this context, a metallic material is preferable.

It has been found that the shape of the button and other accessories is of great importance for the rational and correct application of the present method. In this connection, the shape of the protruding part or shaft is essential.

Thus, it has been found that the following necessary conditions with regard to the shape of the shank in the context of the present invention must be fully met:

1. The protruding part or shaft must be provided with a point so that it can pass through the textile material.

- 8 - Berlin, a. 15.1.1980 56 245 26

2. The projecting part or stem must contain sufficient material in its outer part intended for deformation to allow a sufficiently large deformation head to be obtained.

3. The protruding part or stem must have such increasing dimension and, if necessary, cutting edges so that passage of the protruding member or stem through the textile material to a desired depth will result in tearing off of filaments of the textile material. This is not only necessary in particular in conjunction with soft loose materials, but can greatly enhance the retention property associated with inelastic thin tissues, such as

z. As in tissues for shirts, improve.

4. The protruding part or stem shall not show any sudden changes in dimensions, at least not with respect to the internal part which is not subject to deformation but which is intended to form the part so as to keep the button at a certain distance from that To keep textile material. Therefore, the projecting part or stem is to be made with a smooth transition to the main body of the button and must not have kerfs or raised shapes.

Now, as to the last-mentioned point, it is a known fact that a button and usually not any other similar accessory is to be firmly attached to the textile material. But it is a "neck" provided to achieve a certain mobility of the part and to provide a way to button the buttons. On

- 9 - Berlin _f d.15.1.1980 56 24-5 26

Material in which the buttonhole is made, measure a certain distance to take a position between the button and the material on which the button is attached. It is obvious to provide a spacer against the textile material to ensure a set depth of penetration of the shaft of the button. Therefore, it is desirable to provide a lug on the shank or a flange which protrudes on the shank. The button according to the British patent mentioned above comprises a protruding part or a shank provided with a groove in which the textile material engages. Thus, the groove on its outside shows a widening conical cross section and an approach in the inward direction towards the main body of the button. It is followed with this arrangement, the purpose that the textile material penetrates into the groove after it has passed the conical part.

In the context of the present invention, however, it is shown that such abrupt changes in the cross-section of the protruding part can contribute to the risk of breakage. Thus, both a neck and a kerf will create risks of cracking which, after some time of use, will result in breakage. It is therefore important to avoid said leaky cross-sectional changes and to find other methods to ensure a suitable "hale" length.

According to a particular embodiment of the present invention, the buttons are attached to a garment in the arrangement in which they are intended for the finished garment. This is done in such a way that the garment is buttoned when the buttons are attached.

56 245 26

The apparatus for carrying out said embodiment of the present method is composed as follows: it consists of a holding device for the buttons in the arrangement provided; a stirrup for stretching the garment textile in which the buttonholes are located, and is arranged to hold down the portion of the garment provided with the buttonholes over the protruding portions of the buttons in such a position; that the projecting parts or shafts extend through the buttonholes; it further consists of a strap for stretching the textile material of the garment to which the buttons are to be attached; a rod-shaped tool that presses the stretched textile material of the garment to which the buttons are to be attached against the projecting parts or shafts of the buttons passing through the buttonholes, so that the projecting parts or shafts through the pass said part of the garment, and from a device with a guide or with a plurality of guides, which are connected to an energy transmission, such as a magnetic device, the arrangement being such as to transmit vibrations to the buttons in the ultrasonic range. The guides are arranged in such a way to be pressed against the projecting parts or shafts, so that they are provided with deformation heads to attach the buttons firmly to the garment.

Advantageously, the knob support for the knobs in the arrangement provided is connected to a feeder for advancing the knobs to the fixture.

According to a final feature of the invention, the holding device is formed by a number of profile bars with parts which hold the buttons during the attachment. The profile bars are arranged for forward movement of the buttons from the feeding device.

Execution game

The process can be clearly seen from the attached drawings. Shown is the attachment of the buttons, wherein the respective buttons are shown in three different embodiments. In addition, the apparatus for performing the method is given in an embodiment.

In the drawings, a button in its original form and in attached form and also a device for the attachment of the buttons are reproduced. This indicates the facilities for carrying out the process.

Button. Fig. 7 also shows the button according to the first example of the embodiment in the attached state, wherein use has been made of a variant of the method. Fig. 8 corresponds to a front view of the apparatus and Fig. 9 is a side view thereof. 10 shows a view of a partial cross-section of a detail of the apparatus in a first variant, and FIG. 11 shows a second variant of the same detail. Fig. 12 shows a part of the apparatus in a perspective view and Fig. 13 shows another part.

In Fig. 1, a knob 1 with a main body 2 and a protruding part or shaft 3 is shown. The shaft 3 has a tip 4, which is followed by a conically widening cross section, wherein a transition to a part with a larger radius 5 is recorded. This part with the larger radius 5 then passes into the main body 2 of the knob 1. The projecting part or shank 3 is completely continuous and has no intermediate pieces or spacers with respect to the textile material when attached. If such spacers are desired, they must be provided separately from the shaft 3, e.g. as a spacer ring 6, which can be removed from the protruding part or shaft 3 and is indicated in FIG. 1 by a dot-dash line. In Fig. 2, a knob 7 is also shown with a main body 8 and a protruding part or shaft 9. The shank 9 has a tip 10 and a large radius 11 at the transition to the main body 8 of the knob 7. The protruding part or shank 9 has a conical shape, but, unlike the shank 3, this protruding part resp Shaft 9 a collar 12 of a narrow outer part 13th

- 13 - Berlin, d.15.1.1980

56 245 26

a part 14 with a larger diameter. However, the collar 12 must not be within the position for the textile material, after a deformation head has been formed, this position is indicated in Fig. 2 by a dot-dash line 15.

The button 16 shown in Figs. 3 and 4 also has a main body 17 and a protruding part or shaft 18. The protruding part or shaft 18 is provided with a tip 19 and has at the transition point to the main body 17 over a larger radius 20. The outer part 22 of the shaft 18 has a triangular shape with cutting edges 24 just outside the distance line 21. There is to provide the textile material after the attachment of the button 16. From the part 22 from the protruding part or shaft 18 has a conical inner part 23 with a round cross-section.

In the various examples of the embodiments of the button 1; 7; 16 these are made of a plastic material, with an acetaldehyde resin has proven to be a suitable material. As examples of the embodiments according to the invention are only buttons 1; 7; 16 has been reproduced. The main body 2; However, 8 or 17 may for example be present as a hook, eyelet or push button. The required design of the "neck" may then differ from that described above. However, this proves to be not very significant for the design of the protruding part or shank 3; 9; 18. If a "neck" is not required at all, a spacer, equal to the spacer ring 6, of course, omit.

- 14 - Berlin, d.15.1.1980 56 245 26

The method according to the present invention comprises the following successive works:

a) application of the main body 2; 8th; 17 of the knob 1 according to the invention; 7; 16 with respect to a tool of the construction mentioned above, which serves to exert a counter-pressure.

b) during the time that the textile material is immovable in place, move the tip 4; 10; 19 of the shaft 3; 9; 18 of the button 1; 7; 16 against the fabric in the manner that the tip 4; 10; 19 is inserted through the textile material until the tip 4; 10; 19 the desired position on the protruding part or shaft 3; 9; 18 of the button 1; 7; 16 has reached (see the distance lines 15 and 21 in Fig. 2 and 3).

c) application of a tool under the influence of ultrasonic vibrations seizes the tip 4; 10; 19 of the protruding part or shaft 3; 9; 18 and a pressure, due to the pressure and the ultrasonic vibrations on the side of the material from the main body 2; 8th; 17 of the button 1; 7; 16 is removed, a deformation head has been formed. By this arrangement, the knob 1; 7; 16 or a similar accessory attached to the textile material.

Point b) is of great interest. If we assume that the textile material is woven or knitted, the existing threads are displaced when the tip 4; 10; 19 of the protruding part or shank 3; 9; the button 1; 7; 16 penetrates into the textile material, so

- 15 - Berlin, d.15.1.1980

56 245 26

that the shaft 3; 9; 18 can be inserted through it. However, it has been found that in conjunction with inelastic hard tissues, such as shirt fabric and cotton blouse and / or synthetic material, the penetration of the tapered shank 3; 9; 18 also causes certain threads are torn off, so that free thread ends are formed on the side of the fabric, which is the top 4; 10; 19 of the protruding part or shank 3; 9; 18 opposite. The tearing of the threads can be facilitated and the pressure for the penetration of the tip 4; 10; 19 can be reduced into the textile material if the protruding part or shaft 3; 9; 18 has been provided with cutting edges 24 as shown in Figs. 3 and 4 ·. The cutting edges 24 of the part 22 cause an immediate cutting of certain threads. In connection with said materials which have no flow properties, such a design of the protruding part or shank 3; 9; 18 is not necessary as a rule, but may be of advantage in connection with textile materials which have a structure which is looser, either because of a loose connection between the threads, for example in hosiery, or in view of elastic and / or loose threads ,

It is a fact that the formation of free thread ends is of great importance for the attachment of the buttons 1; 7; 16 has proved. In the use of ultrasound for the deformation, such flow of the plastic material takes place that the threads penetrate into the deformed head and adhere to the plastic material. If the deformation head has only one body on the surface of the

- 16 - Berlin, d.15.1.1980 56 245 26

Textile material should form, this body would rather easily pulled through the textile material by a further extension of the hole through which the projecting part or shaft 3; 9; 18 is inserted therethrough. The risk of pulling out a button 1; 7; 16, which is not attached by sewing, is indeed a fundamental problem associated with such buttons 1; 7; 16th

The described manner of incorporating the threads of the textile material into the material of the deformation head therefore represents a great improvement and a solution to a difficult problem associated with "riveted" ¹¹ buttons.

This way of attaching buttons 1; 7; 16 is of particular importance in the context of fluffy fabrics, which are quite unable to oppose the penetration of the deformation head of resistance. Also, because buttons are not very reliable due to the frictional effect, it was necessary to abandon the use of buttons that were not attached by sewing in conjunction with such materials. However, the present method can also be applied to this case. On the one hand it is true that one or more threads are torn off by a suitable construction of the protruding part or shaft 18 of the knob 16 as shown in Figs. 3 and 4, on the other hand it should be noted that in connection with the use of the proposed Deformation of the tip 19 of the shaft 18 by ultrasonically projecting fibers of the fluffy threads are included in the deformation head.

- 17 - Berlin, d.15.1.1980

56 245 26

An important feature in connection with the point b) is also the formation of the best Längsabmessüng the "neck", which for the limited penetration of the shaft 3; 9; 18 in the textile material is of importance. If this is done by a spacer, for example by the spacer ring 6 according to Pig. 1 or possibly by a separate spacer, causes the formation of a suitable length of the "neck" even during the application of the buttons 1; 7; 16 no problems except the fact that a loose spacer can cause problems. However, the mentioned spacer ring 6 or a loose spacer element as an expansion member of the neck are uncomfortable when the knob 1; 7; 16 must be buttoned, and are therefore to be avoided. Other solutions, however, are obvious. So leads a certain angle of the cone of the shaft 3; 9; 18 with suitable adaptation to the Aufweiteigenschaft the textile material in conjunction with a certain force to a certain penetration of the protruding part or shaft 3; 9; 18 of the button 1; 7; When the shaft 9 of the button 7 is formed as shown in FIG. 2 and if the arrangement of the tip 10 according to FIG. 3 is present to a certain extent, a momentarily increasing force of the insertion during the passage of the narrow outer part 13 or of the triangular outer part 22 is achieved by the textile material. Here, the textile material may have a fairly prominent position as shown by the distance line 15 and 21, respectively. It should be noted that the shaft 3; 9; 18 must penetrate so far that the rapid changes in dimension do not occur in the non-deformed part. In addition, factors as a function of time can be used to form a suitable length of the neck. So is a certain time for the passage through the shaft 3; 9; 18 of the button 1; 7; 16 required, and if the

- 18 - Berlin, d.15.1.1980

56 245 26

Machining time is set in the correct manner, a well-adjusted length of the neck can be achieved. The textile material can further be guided, for example, by a clamping ring around the button layer and this at a certain distance from the main body 2; 8th; 17 of the button 1; 7; 16. Another method operates such that the machine for attaching the buttons 1j 7; 16 is provided with spacers between the main body 2; 8th; 17 of the button 1; 7; 16 and the textile material are introduced and there during the attachment of the button 1; 7; 16 remain. However, it is important to ensure that these spacers during the ultrasound treatment button 1; 7; 16 do not damage.

И-6 · 5 reproduces a button 25 in the attached state. The fabric is indicated at 26, a counter-pressure tool against the main body of the button 26 at 27 and another tool at 28. The button 25 has a protruding part or stem 29, a part of which is applied to a deformation head 30 by pressure application and Ultrasonic treatment with the tool 28 has been deformed. The original appearance of the protruding part or shaft 29 of the button 25 can be seen in FIGS. 1, 2 and 3. The number depends very much on which textile material 26 is used. Thus, the construction according to Hg. 1 with a sharp tip 4 and a uniformly flowing contour of the shaft 3 for hard textile materials 26 is well suited. Jig. FIG. 2 shows a construction that is suitable in connection with somewhat loose textile material 26. Finally, the construction according to FIG. 1 is suitable for an even looser textile material 26.

56 24-5 26

In Fig. B is a Y / reproduction of the deformation head 30. Here, it is indicated that a number of thread ends 31 have been included in the deformation head 30 »

A somewhat different construction of the tool is shown in Fig. 7, here designated 32. In this case, the end surface of the tool 32 has been formed in the form of a recess 33 having an annular shape with a tip 34 in the middle. With this construction, the material can be more easily distributed in the lateral direction. This embodiment is useful in conjunction with plastic materials that are difficult to flow or where a particularly large deformation head 35 is required. The deformation head 35 assumes the shape of the recess 33 of the tool 32, as can be seen from Fig. 7.

Due to the shape of the tool 32 according to FIG. 7, it is not suitable to place the shaft 29 of the knob 25 in a point 4; 10; 19 to end. However, the method may be modified such that, when the method is based on the mold of FIG. 1, the tip 4 of the protruding member 3 is intended to be cut off after passing through the textile material 26 in a tool which is shown in FIG same machine works, with the attachment of the knob 25 is made. A Schnittoberflächeo is created in the height of the shaft 3, which is characterized for example by the line 36 in Fig. 1. It will be readily understood that there is no suitable way of providing the protruding part or shaft 29 of the knob 25 with such a steep surface from the outset, because of the fact that it then encounters difficulties in connection with the insertion of the knob Textile material 26 will give.

One end of said feeding member has a stepped recess 68 with a space open towards the end of the feeding member 67 and communicating with the periphery of the feeding member 67 by means of an opening 69. The feed member 67 is constructed so that it can be pivoted backwards and forwards and slightly more than 180 °, between a position in the immediate vicinity of the profile bar 48 and a position in which the recess 68 points in the downward direction. The feed element 67 moves in a cylindrical drum. There is a feeding device 67 for each profiled bar 48 and the feeders 67 can be axially displaced to form the necessary space.

In Fig. 13 is shown in more detail how the grooves 70; 71 »72 are arranged in the brackets 52 and 53. The inner bracket 52 thus has a groove 70 which is directed in the rearward direction, within which the groove moves, and a narrow groove 72 which is directed in the direction still forward. In the lower position of the brackets 52 and 53, the groove 70 is located immediately below the lower edge of the frame 45 and the groove 71 in the same relative position as shown in Fig. I3. When the two brackets 52; 53 are pulled by the power cylinder 54 and 55 upwards, the grooves 70 and 72 are slightly above the lower edge of the frame 45th

As shown in FIG. 10, the rod-shaped tool 60 may be solid in a first variant. As shown in FIG. 11, a second variant may be pins

73 and an additional rod 74 having holes 75 through which the pins 73 can extend. The pole

74 can be moved by means of a working cylinder (not shown) between two layers in which the rod-shaped tool 60 is located, directly at the rod-shaped tool 60, wherein the pins 73 extend through the holes 75, and in a different position outside of the pins 73 »as shown in FIG. 11 can be removed.

When using the apparatus, the intent is to attach buttons 76 having a head 77 and a protruding portion or shaft 78 to the shaft 78 on a garment in a textile material 79. After attaching the button 76, the shaft 78 must extend through a second fabric 80 of the garment so that the head 77 is on an opposite side of the second fabric 80 relative to the first fabric 79. The projecting portion or shaft 78 of the button 76 must then extend through the buttonhole 81 of the garment fabric 80. Thus, in conjunction with a shirt, vests or similar garment, the buttons 76 with their shafts 78 on the lower garment in front must be correspondingly attached to the textile material 79, while the stems 78 pass through the buttonholes in the upper garment in front of the corresponding textile material 80 extend so that the heads 77 of the buttons 76 are outside the upper garment. Since the attachment at the extremities of the profile concerned

- 24 - Berlin, d. 15 · 1I980 56 245 26

Rods 48 takes place, the buttons 76 must thus be positioned at these ends in such a way that their shafts 78 extend outwardly in the downward direction of the profile bars 48. The profile bars 48 are supplied from their rear end by means of the feed element 67. The mentioned cylindrical drums, in which the feed elements 67 move, must be partially filled with buttons 76, with the feed element 67 moving backwards and forwards in the button stack in the direction of the seal. While the feed element 67 made a series of strokes, it will coincidentally encounter such buttons 76 which are in a position to be received by the recess 68 in the outer end portion of the feed element 67, and the buttons 76 will be the ones shown in Figs FIG. 12 assumes position 76. Buttons 76 which are not in such a position that they can be received in this manner are rejected and the feed element 67 performs an idling stroke. Consequently, the feed elements 67 must perform movements that relate to the consumption of buttons 76 sufficiently often so that the random picking and feeding of buttons 76 is sufficient to always fill the profile bars 48 with buttons 76. When the feed elements 67 are in their upper extreme end position and a knob 76 is supplied, this knob 76 is blown out with the aid of an air jet from the feed element 67 and blown into the profile bar 48. In this case, the knob 76 is hit from the inside, when the air is supplied from a nozzle 82, which is located in front of the opening 69 when the end portion of the feed element 67 has reached with the recess 68 its upper position. Due to the inclination of the profile bar 48th

- 25 - Berlin, d.15.1.198O

56 245 26

For example, the buttons 76 are advanced in the inserted position toward the outer end of the profile bars 48. This transport of the buttons 76 can be facilitated by further compressed air jets or by profile bars 48 which are vibrated.

At the outer ends of the profiled bars 48, the knobs 76 are stopped by the stopper plate 50, which is moved downwardly to its normal position. In the normal position are, therefore, before an attachment of a knob 76 begins, the brackets 52- and 53 in their lower positions with the groove below the edge of the frame 45th

When a series of buttons 76 are to be applied, the textile material 80, ie, the upper garment of a shirt or blouse, such as the collar, and the garment lower fabric, are successively formed with their outer ends into the groove 70 of the lateral portions of the stirrup 52 brought. Subsequently, one of the pedals 64 is depressed with the foot, whereby the power cylinder 54 is operated in such a manner that the bracket 53 will move in the upward direction. The textile material 80 is clamped between the frame 45 and the bracket 52 at the edges of the groove 70. The garment is then held in place and stretched. When the insertion of the button 76 has been made in the correct position, the shaft 78 of the buttons 76 is passed through the buttonholes 81. Appropriately, it may be manually controlled before continuing work. The port setting is that the textile material 79 of the garment, so the lower part of the garment, is inserted into the groove 72 of the bracket 53, the one yet

- 26 - Berlin, d.15.1.1980

56 245 26

Following this, the second pedal 64 is pressed down with the foot, whereby the working cylinder 55 is actuated, which pulls the outer bracket 53 upwards, so that the textile material 79 of the garment through the grooves 72 is clamped. If the attachment of the button 76 is to take place, the garment with the textile material 79 must be placed around the rod-shaped tool 60 so that when the button 76 is attached the garment extends around the rod-shaped tool 60.

Now, the moment of attaching the knob 76 itself follows. This attachment can be triggered sequentially by programming when the power cylinder is operated. As a safety precaution, it is advisable to have additional controls, preferably in the form of a mechanism with two gripping devices for release purposes, which can be operated simultaneously with both hands. This mechanism eliminates the possibility of the hands being in such a position that jamming injury or a similar situation may occur. Regardless of the manner in which work is subsequently performed, there is now a need to operate the power cylinder 62. In this case, the rod-shaped tool 60 is up against the top of the shaft

78 of the knob 76 rotated so that these in the textile material

79 penetrates. The next processing step in the program is now the ultrasonic oscillator is turned on. This generator causes vibrations in the profile bars 48 and simultaneously sets the cylinder 63 in action, so that the rod-shaped tool 60 with a

- 27 - Berlin, d.15.1.1980

56 245 26

certain pressure against the tips of the protruding parts or shanks 78 presses. As a result, the material of the protruding part or shaft 78, which is made of plastic, preferably of an acetaldehyde-based resin, begins to flow, with a head forming on the outside of the textile material 79 of the garment. From Fig. 11 it can be seen that the outside of the textile material 79 of the garment facing downward. In this way, the button 76 is attached to the fabric. If the protruding part or shaft 78 is deformed, the material may reach such a state that it fuses with the textile material 79 (refer to Pig.6). In order to prevent such a fusion from taking place too far at the end of the button shaft, so that the relevant shaft 78 is too long and the deformation head 30; If it is not desired to be sufficiently large on the backside of the material, it may be desirable to push the protruding part or shaft 78 of the button 76 through the textile material 79, as first described. This can be done with the aid of the rod 74, which is held at a certain distance from the rod-shaped tool 60 before the ultrasonic generator is switched on and pushes the shaft 78 of the knob 76 through the textile material 79, as can be seen in FIG. Subsequently, the deformation of the protruding part or shaft 78 of the knob 76 begins with the aid of ultrasound.

When all the buttons 76 have been attached, which thus happens in one operation in the intended arrangement, the brackets 52 and 53 are moved down so that the garment will no longer be clamped. In this case, the stop plate 30 moves in the direction of

.. 28 - Berlin, d.15.4.1980

56 245 26

top, so that the ends of the profile bars 48 are opened, then the buttons 76 are pulled out of the profile bars 48 and the stop plate 50 moves down again to receive the next row of buttons 76. When the garment is removed, the rod-shaped tool 60 must be moved down. The now buttoned garment can the rod-shaped tool 60 on

be taken free end. These operations, which are required after the application of the buttons 76, are programmed in such a way that they can proceed in a suitable order.

Thus, the method of attaching the buttons 76 has the following basic operations after the garment is finished by sewing and the buttonholes 81 are made:

1. The buttons 76 are brought into a holder according to the intended arrangement, wherein the said protruding parts or shanks 78 of the buttons 76 face outward from the holding device;

2. the one textile material 80 of the garment, which is provided with the buttonholes 81, is to be arranged on the holding device such that the shanks 78 of the buttons 76 pass through the buttonholes 81 and the relevant main body 77 of the buttons 76 on the same side of the said textile material 80 of the garment for which they are intended when the garment is buttoned;

3) Joining the protruding parts or shafts 78 of the buttons 76 with the garment fabric 79 on which the buttons 76 are to be attached to the garment fabric 80 with buttonholes 81 between the main body 77 of the buttons 76 and said fabric 79 the garment on which the buttons 76 are attached (see points a) to c) in what has already been said above).

4, removal of the garment from the apparatus.

In the foregoing it has been described how these operations have to be carried out with the aid of the apparatus. In this context, the main function of the apparatus has become clear. However, this main mode of operation can also be achieved in a different way than the one just described. Thus, a large number of embodiments of the small button feeding devices are known, by means of which the parts, in this case the buttons, can be brought directly to a working position in a predetermined position. In an embodiment according to the prior art, use is made of a vibrating feed chute in which the small parts are subjected to a forward feed by vibration in a random manner and in which certain catching devices are provided for the separation of particles. Such a device may be used in place of the feeding device shown in Fig. 12. Also, the holding device for holding the garment may have different constructions, but preferably it must be made of one certain kind of one
