Zipper

专利摘要:
A slide-fastener stringer has a tape formed from a ground weave with double wefts interwoven with a warp and a coupling element disposed along the edge of the tape and held thereto by binding warps. The coupling element is of the type in which a synthetic resin monofilament is coiled to form coupling heads whose shanks are disposed one above the other so that they have a common projection in the slide fastener plane. The shanks are connected to those of successive heads by bights. The coupling warp comprises a plurality of warp yarns whose patterns are offset by two picks and which each pass over two coupling elements, under a double weft between coupling elements, over another coupling element and then under the next coupling element in a repeating pattern.

I
The invention relates to light industry products, namely, zippers for a wide range of applications.
A zipper is known, containing 5 woven carrier tapes, each with a main thread and double loops of continuous ground weft yarn lying next to each other, which are located under the locking links in the pockets of the main thread of the carrier tapes; The dyes of the closing links made of artificial monofilament in the form of a spiral with the arrangement of the shoulders of the links in the projection on the plane 15 of the fastener one below the other, and the rear connecting elements of the links encompass the attached main loops.
The disadvantage of the zipper is that the locking links can be pulled out of the carrier tapes when. cross stretch stitching. In addition, this fastener does not have sufficient flexibility and, with longitudinal tension or shrinkage, does not have 25
the carrier tapes change the distance between the shoulders of adjacent locking links located in the same pockets of the main thread, as a result of which the pitch changes.
The purpose of the invention is to increase the strength and flexibility of the zipper.

This goal is achieved by the fact that the zipper, containing woven carrier tapes, having in each rapport the main threads and lying next to each other double loops of a continuous soil weft thread, which are located under the locking links in the pockets of the main thread are not Ribbons, rows of locking links made of artificial monofilament in the form of a spiral with the arrangement of the arms of the links in the projection on the fastener plane one above the other, the rear connecting elements of the link 6 are covered with attached basic threads, double loops of dirt one the exact threads are additionally located between the adjacent locking links, and the attached main threads pass over the bearing ribbons and are shifted by two weft inserts, while each main thread alternately in each rapport covers from above a pair of locking links and passes from below under a double loop of the earth weft yarn, and then covers the next closing link from above, with the stitched main thread covering the last link of each rapport from below and passing under the double loop of the ground weft thread located the last link of rapport. Figure 1 shows the zipper, top view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1. The zipper contains woven carrier tapes 1 and rows 2 of the closing links made of artificial monofilament stuck in them (for clarity, the ground weft 3 of the carrier tape 1 is shown thick, and the main threads C are thin. In Fig. Attached. Main strands 5,6 , 7, and 8 are shown by thick, solid, dash-dotted, dotted, small or dashed large lines, respectively.The carrier tapes 1 are made of main yarns and double ducks of continuous ground weft 3 lying next to each other 3. Each row of 2 loops It is complete in the form of a deformed helix consisting of individual closing links 10, including shoulders of closing links 9, projected on a plane one above the other, connecting heads 11 and rear connecting elements 12. Double ducks of continuous ground weft yarn 3 are located both under the closure links 10 and between the closure links in the pockets. 13 main threads of the carrying tape 1. On the It section of double wefts of the soil weft 3 and of the soil main threads 4, the return main threads 5,6 7 and 8 ensure thatthere are locking links 10 with carrier flap 1. Sew main threads 5,6,7 and 8 pass over carrier tape 1 and are shifted by two weft 3. At the same time, 9 34 each sewing main thread (for example 5) alternately in each rapport covers from above, a pair of locking links 10 and passes under the double loop of a ground weft yarn 3, and then it covers the next closing link from above, while the stitched main thread 5 covers the last locking link 10 of each rapport from below and passes under the double loop of the earth thread 3, located nd before this last link. 1-3, four stitching main yarns, 7 and 8, are shown. However, fewer or more such sewing yarns may be provided. They can also be grouped together. The application of the proposed zipper allows you to maintain the spacing of the locking links under all loads and ensures the softness and flexibility of the zipper. Claims A zipper containing woven carrier tapes, having in each rapport the main threads and double loops of a continuous ground weft lying next to each other, which are located under the closing links in the pockets of the main thread of the supporting tapes, a row of closing links made of artificial a monofilament in the form of a spiral with the arrangement of the arms of the links projected onto the plane of the fastener one above the other; the rear connecting elements of the links are covered with attached main threads, characterized in that and the strength and flexibility of the zipper, the double loops of the primer weft are additionally located between adjacent locking links, and the stitching main yarns pass over the carrier tapes and a weft is shifted by two inserts, while each thread in each rapport spans a pair of locking links and passes below the double loop of a weft yarn, and then covers the next closing link from the top, while the stitched main thread covers the last link of each 5 rapport from below and Odita under dvoinoy loop ground weft thread, placed in front of the last link of rapport. . 9367934 Sources of information taken into account during the examination 1.
