Description

Tape

Technical Field

The present invention relates to a tape to which a zipper, a snap, a curtain suspension device or other member can be attached, and more particularly to a tape having a low weft density and excellent flexibility but having a stable woven structure profile.

Background

In order to stabilize the woven structure profile against pattern deviation, the conventional tapes are woven by increasing the density of warp and weft yarns so as not to generate gaps in the woven structure. With such a woven structure, the connector attachment region of the tape, such as a zipper, snap button, curtain hook, or the like, always maintains a stable structure, so that the respective members can be firmly connected without a deviation of the pattern in the tape, and the respective members can exert their stabilizing function.

However, according to the above-described woven belt, since the belt-inherent region in the belt, i.e., a portion where the belt is attached to an object by sewing or the like, has the same woven structure as the attachment region of the connector, the belt-inherent region lacks flexibility, and the belt cannot be firmly attached and cannot be well fixed to the object to be attached.

On the other hand, fabrics interwoven by both weaving and knitting have been disclosed in, for example, U.S. patent nos. 3,880,202 and 3,885,601. According to these publications, a plurality of weft yarns are arranged in the width direction of the cloth, and each weft yarn is folded back in each of a plurality of segment regions in the width direction of the cloth to be interwoven with warp yarns to be woven. Meanwhile, a coil formed at each weft turn-back end is caught by a coil formed at the weft turn-back end in the adjacent region to produce a cloth.

Therefore, the cloth obtained in this way has a structure in which a plurality of narrow bands are connected to each other by means of stitches in the width direction, so that no shift in the weft pattern occurs. However, in the stripe portion where each coil is housed, the cloth is easily wrinkled in the width direction and easily stretched or shrunk, thereby lacking in stability as a structure of the cloth. Therefore, such cloths are not easy to handle. In this cloth, the stripe portions are formed at equal intervals over the entire width of the cloth in the entire width direction of the cloth. Therefore, it is not suitable for a belt to which the above-mentioned connector is attached.

Disclosure of Invention

The present invention has been made in an effort to solve the above-mentioned problems, and therefore, it is an object of the present invention to provide a band having excellent attachment stability to various connectors and fixing performance to an object to be connected. Another object of the present invention is to provide a tape which, despite its very low weft density and excellent flexibility, does not undergo shifting of the weft pattern, thereby ensuring excellent productivity and structural stability, as well as excellent workability in attaching it to the objects to be attached.

In order to attach the above-mentioned coupling elements of the zipper or other members such as snaps or the like to the tape, the structure of at least the attachment region needs to lack flexibility and structural stability. On the other hand, in order to attach a belt having such a member to an object to be attached, such as a garment or bag, by sewing or other means, the belt needs to be well suited for attachment to the object.

Recently, tapes having the above-mentioned members, such as zippers or snaps with tapes, have been used to attach to relatively thin, flexible objects requiring attachment, such as baby clothing or undergarments. Therefore, there is a strong need for a strap natural area made of a thin, flexible material that is an attachment area of a strap attached to an object. The same need exists even when the object has a certain degree of rigidity.

That is, this type of belt requires zones with opposite functions: a region of lack of flexibility and, if possible, a region of excellent flexibility. Furthermore, both regions must be structurally stable.

The inventors of the present invention paid attention to the fact that, by forming a knitted region using a knitting needle in a woven structure, the deviation of the weft yarn pattern can be suppressed, so that the woven structure can be stabilized even in a tape whose basic structure is obtained by weaving, as in the cloth disclosed in the above-mentioned U.S. patent specification, despite having a low weaving density and a sparse weaving pattern. Furthermore, the inventors have found that it is advantageous to form the loops of the woven portion using weft yarns running across substantially the entire width of the tape in order to stabilize the woven structure.

The first aspect of the present invention has the basic features obtained by such a concept. In this feature, there is provided a tape woven using warp yarns and weft yarns, the tape being divided in its width direction into a connector attaching region and a tape attaching region, the tape attaching region including weft yarns for forming loops and warp yarns interwoven with the weft yarns, the connector attaching region being formed by weaving only the warp yarns and the weft yarns, characterized in that: a stitch is formed in the tape-attaching region by a continuous weft yarn which passes through the entire width of the tape and serves as a knitting yarn, while the stitch is caught by a stitch which runs parallel to each other, is arranged in parallel in the longitudinal direction of the tape, and is formed by other continuous weft yarns serving as knitting yarns.

In other words, according to the present invention, the strap is divided into a connector attachment area to which a connector such as a zipper, a snap, a curtain hanging device or the like is attached, and a strap attaching area to which a strap attaching area is attached to an object such as clothes and bags. Then, each time a weft yarn is inserted and the weft yarn is caught by a loop formed by the weft yarn inserted next or thereafter, the weft yarn passes substantially the entire width of the tape, thereby causing each loop to be formed in at least a part of or the entire area of the tape-inherent region. Then, weaving with the weft yarn in the longitudinal direction of the tape is repeated.

Due to the fact that such a weaving pattern prevents weft yarn displacement and the inherent flexibility of the belt is provided, it is very suitable for attachment to the object to be attached and ensures the smoothness of the attachment. Also, due to the presence of the weaving structure, the weaving yarn, e.g., warp yarn, in the connector attachment region is prevented from being shifted toward the belt-inherent region, thereby stabilizing the weaving structure in the connector attachment region to ensure stable connection of the connector.

On the other hand, the present invention does not specify the woven structure of the above-described attachment region of the connecting member. The reason is that the woven structure of the attachment region of the connector depends on the type of the connector and its connection state, such as whether the connector is formed of synthetic resin and integrally molded on the band, or the connector is formed of metal and integrally formed on the band by crimping. Thus, according to the invention, the connector attachment area can be formed solely by a woven structure in which warp and weft yarns are interwoven with one another, or other yarns are woven into parts of the woven structure, or, in addition, a knitting pattern is knitted by weft yarns or yarns additionally provided in parts of the woven structure.

The present invention also provides a feature of the belt natural zone. According to the present invention, there is provided a tape in which a tape-inherent region is constructed into a general woven structure composed of weft yarns for forming loops and warp yarns interwoven with the weft yarns. That is, according to the present invention, there are both a normal weaving structure in which warp yarns and weft yarns are interwoven with each other and a weaving structure in which loops formed by weft yarns are nested in a tape-inherent region by loops formed by weft yarns inserted next or thereafter. With such a feature, in the tape-specific region, the warp and weft patterns do not deviate, and therefore the tape structure can be stabilized. And the belt-inherent region is well suited to the object to be attached, and thus can be firmly and smoothly attached to the object by sewing or the like.

Preferably, a tape is provided wherein a pattern of warp knit threads is also nested with the nested loops. The warp knitting yarn is provided separately from the warp and weft yarns and is caught in the caught portions of the stitches formed by the weft yarns while forming a warp knitting pattern to be integrally knitted. Therefore, the expansion/contraction of the tape natural region in the longitudinal direction is greatly suppressed, so that the structure of the tape natural region is more stable than that woven with only the weft yarns.

Further preferably, there is provided a tape in which the connector attachment region is formed by only interweaving warp and weft yarns. With such a structure, stability and a certain degree of rigidity as a woven fabric structure are obtained, and stable connection of the connecting members is ensured.

Still preferably, a tape is provided wherein the stitches are formed by all weft yarns adjacent to each other, and the individual stitches are successively nested with each other in the longitudinal direction of the tape to form a continuous row of stitches in the longitudinal direction of the tape. With such a configuration of the stitch row, when the tape-inherent region is sewn to an object to be attached, the stitch row can serve as a guide line for sewing. Thereby making the sewing work reliable and stable.

Preferably, a tape is provided in which the entire tape-resident region is formed by the weft yarn looping over each loop. That is, according to the present invention, there is no warp yarn in the tape-inherent region, so that the entire region thereof is formed by the weft knitting structure. Therefore, the intrinsic region of the tape of the present invention has excellent flexibility and stretch properties as in general weft-knitted products. Therefore, this is very suitable for clothes such as knitted cloth, so that waves or the like which tend to occur on the objects to be joined when sewing the tape never occur, and a beautiful and refined product is obtained. In this case, the woven structure of the attachment region of the connecting member is not limited to any particular form, but a general woven structure with warp and weft yarns as mentioned above is preferable in terms of structural stability.

Preferably a tape is provided in which the weft yarn consists of two yarns running in a reciprocating manner in the same warp yarn opening. As mentioned above, it is assumed that the above-mentioned weft thread consists of a single weft thread in the usual single weft manner, but according to the invention a known narrow-width needle loom is applied, so that the weft thread consists of two threads running in a reciprocating manner through a shed formed by a thread opening. Therefore, when the weft density is set to be large in a tape of a general type to prevent the deviation of the weft pattern, as described above, the tape is very stiff, so that it is particularly difficult to adapt itself to an object to be attached, and moreover, there is a problem in attaching to the object by sewing or the like. However, according to the present invention, by forming a coil-in-coil structure by weft yarns, not only flexibility is obtained but also deviation of weft patterns does not occur, and a stable structure can be obtained even when the density of weft yarns is set to be smaller than the conventional weft density. This in turn leads to a reduction in the amount of weft yarn used, whereby lower costs can be achieved.

Still preferably, there is provided a tape wherein the weft yarn is comprised of two yarns running in a reciprocating manner in the same warp yarn opening and the loops are formed by one of the two yarns. In this case, one of the two yarns forming the weft yarn is knitted to form a stitch, and the other is inserted in a straight line into an opening as a normal weft yarn. As a result, the knitted structure is increased in the entire woven structure of the belt intrinsic region, so that the belt intrinsic region is provided with further improved flexibility and structural stability. Of course, two yarns forming the weft yarn may be used to form a loop.

Preferably, there is provided a tape in which each of two yarns forming a weft is formed into a loop at a predetermined pitch in a width direction of a natural region of the tape, and the loop of each yarn is caught by a loop formed by a yarn corresponding to an adjacent weft. According to the present invention, since the weave pattern formed by entangling the individual loops is regularly provided in the belt natural region at predetermined intervals, uniform flexibility and structural stability throughout the entire belt natural region are obtained.

Preferably, there is provided a tape in which the weft yarns composed of two yarns running in a reciprocating manner in the same warp yarn opening include one or more first weft yarns and a second weft yarn folded back in the tape proper region, the first weft yarns being followed by the second weft yarns to form a woven tape edge portion located at the outer side edge of the tape proper region, while a loop formed at the folded back end of the first weft yarn adjacent to the second weft yarn is caught by a loop formed at the folded back end of the second weft yarn.

Thus, the tape edge portion is woven by interweaving a plurality of warp yarns arranged in parallel with the second weft yarn at an interval of one or more first weft yarns. As a result, each warp yarn extends between the loop-shaped one or more first weft yarns toward the outside of the tape edge portion, so that a tape having a binder yarn at the edge thereof is obtained, and hence a design effect can be expected.

Further preferably, a tape is provided wherein a reinforcing yarn is inserted in the tape edge portion while the reinforcing yarn is looped over the stitches in the tape natural region in which the first weft yarn is looped over the second weft yarn. The insertion of the reinforcing yarns not only improves the strength of the belt edge portions but also stabilizes the structure of the belt edge portions.

An arrangement of the attachment area of the connector of the belt and the intrinsic area of the belt is defined. It is preferable to provide a belt in which the connector attaching region is provided in the middle in the width direction of the belt and the belt attaching region is provided on both sides in the width direction of the belt. It is also preferable that the connector attachment region is provided on one side in the width direction of the belt and the belt attachment region is provided on the other side in the width direction of the belt. It is still preferable that two or more connector attachment regions and belt intrinsic regions are alternately provided.

The arrangement of the attachment area of the connector and the intrinsic area of the band is different because the connection position is changed depending on the type of the connector. In one aspect of the present invention, it is preferable that, in the belt, a snap is attached as a connecting member to a widthwise intermediate portion thereof. As a typical example of another aspect of the present invention, there is provided a fastening tape or terminal tape for a slide fastener in which a connector or curtain suspension device is connected as a connecting member along an edge thereof.

Finally, there is provided a tape in which the upper/lower leg portions of each connector section of the coil-like connector row including the slide fastener are disposed above the weft yarns in the connector attachment region while the upper/lower leg portions are integrally tied together with the weft yarns by the warp yarns, so that the stitch rows of the weft yarns are formed in the vicinity of the tape inherent region of the connector attachment region, whereby a typical tape can be provided which can prevent the connector attachment region from being shifted toward the tape inherent region having a smaller warp yarn density and having flexibility. As another example, the tape may be used for a snap tape in which a plurality of snaps are provided in the width direction thereof, which extend in a straight line along the longitudinal direction thereof.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Fig. 1 shows an exemplary embodiment of the present invention, and is a plan view showing rows of connectors by partially breaking them, while omitting a view of a central portion in the width direction of a fastener tape which is a tape according to the present invention incorporating rows of coil-shaped connectors of a slide fastener in side edges thereof. For the purpose of describing the following embodiments and modifications, like reference numerals designate substantially like parts for ease of understanding.

Although the various warp and weft yarns are shown in fairly small sizes throughout the drawings for ease of understanding, in practice yarns of the desired size are used depending on their purpose.

Moreover, while the woven structure is shown roughly, it actually has the desired degree of sophistication.

A fastening tape 101 according to the embodiment shown in the drawings comprises a fastener row attaching region 102 and a tape attaching region 103, the region 102 being a component mounting region of the present invention, and the region 103 being to be attached to an object. In the above-described connector row attachment region 102, a connector row ER is integrally incorporated at the same time as the fastening tape 101 is woven and edged therein. A bottom weft thread 20, which is a constituent thread of the fastening tape 101, is inserted in double picks into the shed of the warp openings by a weft-guide needle bar reciprocating in a narrow-width needle loom, and thus comprises double threads. The warp consists of a bottom warp which constitutes the basic structure of the fastening tape and a binding warp for the above-mentioned connector row ER.

The 10 component array binding warp yarns 2 to 5, 7, 8, 10 to 13 are placed in the above-mentioned connector row attachment area 102. A plurality of bottom yarns 1, 6, 9, 14 to 18 to 32 are placed in the tape natural region 103 and the connector row attachment region 102. These warp yarns are arranged in succession in the order of the numerals from the outside of the attachment area 102 of the connector row and are supplied to a weaving machine (not shown).

A plurality of connector portions E continuously molded into a loop shape using a monofilament made of synthetic resin are woven into the woven structure of the connector row attachment region 102 to be edged. The connector portion E is composed of a connector EH extending outward from the connector row attaching region 102 of the fastening band 101, upper/lower leg portions L extending in parallel from both ends in a direction perpendicular to the fastening band 101 of the connector EH toward the inside of the fastening band 101, and a connecting portion RC for connecting each end of the upper/lower leg portions L so that both the upper/lower leg portions L of the connector portion E are adjacent to each other in the front-rear direction of the band.

The connector portion E is guided by a support rod (not shown) that reciprocates by a predetermined length from one end of the tape to the inside of the tape when the under weft yarn 20 is inserted while being inserted and molded in double picks. Therefore, in this embodiment, the weft inserted in double picks of the bottom weft yarn 20 is located below it along the upper/lower leg portions of the connector portion E, respectively.

A needle (not shown) is inserted into an annular return end on the side of the tape natural region 103 of the bottom weft yarn 20, and the needle projects beyond the former annular end by hooking the inserted return annular end of the bottom weft yarn 20 at the next position. Then, the looped ends are sequentially joined together to form a tape edge portion 103a of the tape attaching region 103.

According to this embodiment, among the above-described binding warp yarns 2 to 5, 7, 8, 10 to 13, the adjacent two binding warp yarns 2 and 3 adjacent to the connector EH of the connector section E are positioned above the upper/lower leg portion L while their repeat units are shifted by one pitch of the connector section E in the longitudinal direction of the tape, and then pass under the bottom weft yarn 20 composed of two yarns disposed below the upper/lower leg portion L at the next position. Accordingly, this is repeated as a unit, so that the connector portion E is continuously woven into the fastening tape 101 and bound therein.

The binder warp yarns 4 and 5 following the two binder warp yarns 2 and 3 run over the upper/lower leg L of the two connector segments E while being offset by a pitch as described above and run between the lower/upper leg L of the connector segment E in the next position and the bottom weft yarn 20 consisting of two yarns below the upper/lower leg L. Furthermore, it runs under the ground yarn 20 which consists of two yarns and is located below the upper/lower leg L of the next connector part E. Then, the procedure is repeated. A bottom warp yarn 6 following the two binding warp yarns 4 and 5 is provided which runs alternately over and under the adjacent bottom weft yarn 20, so that it is always situated below the connector part E.

The binder warp yarns 7 and 8, which are located at the inner side of the belt adjacent to the bottom warp yarn 6, run with the same repeat unit as the two binder warp yarns 4 and 5. A bottom warp yarn 9, which is arranged on the inner side of the belt adjacent to these binding warp yarns 7 and 8, runs alternately over and under the adjacent bottom weft yarn 20 like the bottom warp yarn 6, so that it is always situated under the connector part E.

Four tying warp yarns 10 to 13 provided on the inner side of the belt following the bottom warp yarn 9 are used to tie the connecting portions RC of the upper/lower leg portions L of the connector portion E. Each of the binding warp yarns 10 to 13 runs in the same repeat unit as the binding warp yarns 2 and 3 arranged in the vicinity of the connecting head EH. In other words, the binding warp yarns 10 to 13 are located over a portion in the vicinity of the connecting portion RC of the upper/lower leg L and run under the bottom weft yarn 20 disposed under the upper/lower leg L at the next position while the repeat unit is shifted in the longitudinal direction of the tape by one pitch of the connector portion E. This step is repeated to sequentially weave the connector portion E into the fastening tape 101 and bind therein.

Also, in this embodiment, the bottom warp yarns 14 to 31 to 38 and the bottom weft yarn 20 constituting the tape intrinsic area 103 are arranged to cross each other in a zigzag pattern to form a so-called plain weave structure. The warp density of the connector row attachment area 102 and its adjacent binding warp yarns 2 to 5, 7, 8, 10 to 13 and bottom warp yarns 1, 6, 9, 14 to 18 is higher than the density of the other warp yarns in all warp yarns to ensure stability and a certain degree of stiffness of the structure in the connector row attachment area 102 and its adjacent.

With the above feature, in the fastener tape 101 of this embodiment, when producing a slide fastener, the fastener tape 100 is configured by combining the above-described fastener element rows ER, and the fastener element rows ER of a pair of fastener tapes 100 opposing each other are joined to each other. In this state, the connector row ER is partially cut out in a desired length with a space of a predetermined length of the zipper to be finally completed to form a space portion. At this time, at one end portion on the connector EH side of the fastening tape 101 in the spacing portion, the bottom warp yarn 1, the tying warp yarns 2 and 3 run alternately up and down the bottom weft yarns 20 arranged in parallel while their pitches are shifted by a distance with respect to one weft yarn 20. For this reason, the respective warp yarns 2 and 3 will not undulate upward after the formation of the spacing portions. Therefore, in the subsequent manufacturing process of the slide fastener, for example, when a stopper is attached or a slide slider is inserted, the influence of the warps 2 and 3 is not generated, and the manufacturing process thereof is stabilized, thereby providing a high quality product at a high speed.

According to this embodiment, whenever the weft yarn is inserted in double picks using an appropriately provided knitting needle, the loop 21 formed by the weft yarn 20 of the greatest feature of the present invention is formed between three bottom warp yarns 36 to 38 near the outer edge of the tape proper region 103 and a bottom warp yarn 35 adjacent to the inner side of the tape proper region 103, and is also formed between a bottom warp yarn 33 provided in the tape proper region 103 passing over a single bottom warp yarn from the bottom warp yarn 35 inward and a bottom warp yarn 32 further inward adjacent to the tape proper region 103. The stitch 21 at the previous position is caught by the stitch 21 at the next position, so that the stitch rows W1, W2 form two knitting patterns continuing in the wale direction. The above-described stitches 21 of this embodiment are formed by a single yarn of the under weft yarn 20 comprising two yarns while the other yarn runs in a straight line without forming any stitches.

In the form of such a weaving pattern, the deviation of the weaving pattern of the weft yarns 20 does not occur at the outer edge of the tape inherent region 103, although the weft yarn density is low. Furthermore, because the entire belt natural area 103 is flexible, it is well suited for attachment to an object. Further, since the two stitch rows W1, W2 function as sewing guides, sewing work attached to an object can be performed efficiently and accurately. Since one of the ground weft yarns 20 composed of two yarns forms the loop 21 and the other yarn runs straight without forming any loop, the belt intrinsic region 103 has a structure having a remarkable stability as much as that of woven cloth. This pattern allows the rows ER of links to be connected in a steady state.

Although according to this embodiment, as described above, the two coil rows W1, W2 extending in the stripe direction are formed near the outer edge of the belt intrinsic region 103, it is not limited to the two mentioned rows, and any number of coil rows may be formed at any position in the width direction of the belt intrinsic region 103 by the plurality of rows of warp yarns. For example, when the bottom weft yarn 20 is used to form the loop 21 in the vicinity of the connector attachment region 102 of the tape inherent region 103, even when the bottom warp yarn is designed to have a sparse weaving density, no deviation occurs in the warp yarn, whereby the stability of the structure in the connector row attachment region 102 can always be obtained.

Fig. 2 shows a modification of the above-described fastener tape 100. Although in the above-described fastener tape 100, the ground weft yarn 20 is inserted for each pitch between the respective element portions E of the connector row ER, according to the present modification, the double pick ground weft yarn 20 is inserted twice for each pitch between the respective element portions E of the connector row ER. Therefore, assuming that the size of each of the warp and the bottom weft yarns is the same as that of the above embodiment, the weft density in this case is twice that of the fastening tape 101 of the above embodiment.

FIG. 3 is another modification of the fastener tape for a slide fastener as shown in FIGS. 1 and 2. According to the present modification, the connecting member (row) is not woven into the fastening tape 101, but after the fastening tape 101 is manufactured, a connecting member E of synthetic resin or metal is mounted along one edge by molding or crimping integrally. For this reason, during the manufacturing process of the fastening tape 101, two core threads (core threads) 30 and 31 are woven in along the outer side edges of the connector attachment region 102 to prevent any connector E from slipping out. Other features are the same as the modification shown in fig. 2.

Fig. 4 shows a third modification of the embodiment shown in fig. 1. According to this variant, the fastening strip 101 is woven separately as in the variant shown in fig. 3. Unlike the position shown in fig. 1, two coil rows W1 and W2 are formed between the fourth bottom warp yarns 35 to 38 and the fifth bottom warp yarn 34, and between the bottom warp yarn 33 and the bottom warp yarn 32, respectively, counted from the outer edge of the tape inherent area 103. In the connector attachment region 102, a coil-shaped continuous connector row ER is provided, and a core wire 30 is inserted in the longitudinal direction and fixed in the connector row attachment region 102 by sewing.

Fig. 5 shows a second embodiment of the invention, in which each of the weft threads 20, i.e. the first and second weft threads 20a and 20b, which are composed of two threads, are arranged in the two thread rows W1 and W2 alternately. The stitches 21a constituting the stitch row W1 provided on the inner side of the tape-inherent region 103 are formed by the first yarns 20a, and the stitches 21b constituting the stitch row W2 provided on the outer side of the tape-inherent region 103 are formed by the second weft yarns 20 b. By forming the stitches 21a and 21b using each of the two yarns constituting the weft yarn 20 in double picks, this allows the first and second weft yarns to function as a stitch and a weft yarn, respectively, so that the structure and flexibility of the tape can be equally set.

Fig. 6 shows a third embodiment of the invention, in which each stitch is formed by a weft thread 20 in the entire tape intrinsic region 103. Therefore, in the present embodiment, there are no bottom warp yarns in the tape inherent region 103, so the tape inherent region 103 is constituted only by the weft yarns 20. On the other hand, the connector attachment region 102 is composed of a woven structure formed by collecting the binding warp yarns and the bottom warp yarns like the above-described embodiment and modification, although the drawing thereof is omitted. According to the present embodiment, each of the yarns 20a and 20b of the weft yarn 20 composed of two yarns in double picks forms the stitches 21a and 21b, respectively, so stitch rows are alternately formed in the width direction of the tape inherent region 103.

According to the present embodiment, as can be understood from fig. 6, since the tape intrinsic region 103 is woven in a so-called knitted structure, flexibility and stretch property of the weft knitted structure can be obtained in the region 103. For example, when the object to be joined is a knitted fabric, the above-described tape intrinsic region 103 is very suitable for joining to a knitted fabric product. Therefore, when it is sewn to the object, waviness or the like along the sewing thread does not occur, which easily occurs when a general woven tape is sewn, whereby a high-quality product having a beautiful appearance can be produced.

Fig. 7 shows a fourth embodiment of the invention, from which it can be understood that equivalent stitches 21a, 21b are formed by two threads 20a and 20b, the two threads 20a and 20b being formed by doubling the bottom weft thread 20, which consists of two threads 20a and 20b in the same position in double picks. These coils are nested by the coils 21a, 21b formed by the twin wires 20a and 20b at the next location to form a fringe. Such a feature reliably prevents the pattern of weft yarns 20 from shifting, thereby obtaining a tape-inherent region 103 which is structurally stable and has the particular flexibility of the knitted structure.

Fig. 8 shows the woven and knitted structure of the belt natural region 103 according to the fifth embodiment, which is more stable than the belt natural region 103 of the fourth embodiment and suppresses extension in the longitudinal direction. In this embodiment, a chain stitch 22 is additionally knitted into the courses W1 and W2 of the woven and knitted structure shown in FIG. 1 above. The additional use of the chain stitch 22 stabilizes the profile of the knitted structure, in particular by inhibiting the stretch behavior in the longitudinal direction. Although in the present embodiment the chain-like thread tracks are applied as warp threads, it is also possible to knit warp knitting or both thread tracks simultaneously or separately.

In the sixth embodiment shown in fig. 9, the tape intrinsic region 103 is provided on an insertion side of the weft yarn 20 composed of two yarns 20a and 20b in double weft. The tape edge portion 103b is woven by interweaving the fold return line 20b at the previous insertion position with the three bottom warp yarns 36 to 38 at the next insertion position.

Fig. 10 shows a modification of the edge of the belt marginal portion 103a of the belt intrinsic region 103 in the first embodiment. According to the first embodiment, the selvage portions 103a are formed by looping over the turn-back ends of the two yarns 20a and 20b which are double-wefts in the front and rear positions. However, according to the present modification, a selvage-forming yarn 23 is additionally provided, and the selvage portion 103c is formed by inserting stitches formed by the selvage-forming yarn 23 into the stitches at the turn-back edges of each of the double-weft yarns 20a and 20b at the preceding and subsequent positions.

Fig. 11 shows a seventh embodiment of the present invention. According to the various embodiments and modifications described above, the weft yarn 20 is composed of two yarns 20a and 20b in a double weft. However, according to the present embodiment, a general weaving machine that inserts a weft of one yarn is applied, and therefore, the under weft yarn 20 is composed of a single yarn. With this arrangement, if the same size yarn is used, the number of yarns used will be reduced to 1/2 compared to the other embodiments, as will be readily appreciated. Moreover, due to the presence of the courses W1 and W2 formed by the weft yarns 20 in the tape natural region 103, abrasion of the pattern can be effectively prevented. Moreover, since the weft yarn 20 is composed of a single yarn, a very thin, flexible tape natural region 103 is formed, although having the same structure as the above-described respective embodiments.

Fig. 12 to 15 show an eighth embodiment of the present invention and a modification thereof.

According to the embodiment shown in FIG. 12, a continuous loop group 21 'is formed between the innermost bottom warp yarn 32 of seven bottom warp yarns 32 to 38 on the outer side edge of the tape natural region 103 and a bottom warp yarn 31 inwardly adjacent to the bottom warp yarn 32 by continuously looping over loops 20-1' formed at the turn-back ends of two yarns 20a-1 and 20b-1 of the double weft of three first weft yarns 20-1. A following second bottom weft yarn 20-2 is inserted into the last loop 20-1' and weaved with seven bottom warp yarns 32 to 38 arranged on the outer edge of the tape inherent region 103. It is then turned back and interwoven with the seven bottom warp yarns 32-38 described above to weave an edge portion 103 d.

Then, a loop 20-2 ' formed at the turn-back ends of the two yarns 20a-2 and 20-b of the second bottom weft yarn 20-2 from which the tape edge portion 103d is woven is caught by the loop 20-1 ', and the loop 20-1 ' is formed at each turn-back end of the two yarns 20a-1 and 20b-1 of the first bottom weft yarn 20-1 that is the most preceding of the three first bottom weft yarns 20-1 inserted in succession. This operation is repeated.

In such a structure, seven bottom warp yarns 32-38 are interwoven by the second bottom weft yarn 20-2 at the insertion of each fourth weft yarn, so that one loop extending outward is formed between the mutually adjacent second bottom weft yarns 20-2. As a result, a coil-shaped covering yarn is formed along the outer edge of the tape intrinsic region 103, thereby obtaining a tape having a specially shaped tape edge portion 103 d. Therefore, in addition to the above-described effects, a design effect is also produced.

In the modification shown in fig. 13 and 14, the arrangement of the first bottom weft yarn 20-1 and the second bottom weft yarn 20-2 is changed as compared with the foregoing embodiment. According to a modification shown in fig. 15, two first bottom weft yarns 20-1 and two second bottom weft yarns 20-2 are alternately arranged. With respect to the second bottom weft yarns 20-2 arranged in parallel, the second bottom weft yarn 20-2 in the next position is inserted into one loop at the turn back end of the two yarns 20a-2, 20b-2 of the double weft of the previous second bottom weft yarn, after which the second weft yarn 20-2 in the next position is folded back and interwoven with seven bottom warp yarns 32 to 38 to perform weaving.

Fig. 16 and 17 show another embodiment. According to the embodiment shown in FIG. 16, a selvage-carrying yarn 24 is additionally provided as opposed to the embodiment shown in FIG. 13 and interwoven with the second bottom weft yarn 20-2 and seven bottom warp yarns 32-38 to weave a selvage-carrying portion 103 e. A loop 24 ' at the inner side thereof is fitted with the loop 20-2 ' at the end of the second weft yarn 20-2 and the loop 20-1 ' at the turn-back end of the first weft yarn 20-1 inserted into the next position. According to the embodiment shown in fig. 17, the trapping of the edgewise yarn 24 with the first bottom weft yarn 20-1 is performed twice, instead of once, by means of the stitches 24'. By interlacing the selvage yarns 24 in this manner, a selvage portion of the belt intrinsic region 103 is provided with greater strength and rigidity.
