Technical Field

The invention relates to the technical field of weaving, in particular to a zipper strip and a zipper strip weaving machine.

Background

With the rapid development of the technology, since the zipper has the advantages of convenient opening and closing and durability, the zipper is widely used, for example, the zipper is used for ready-made clothes, leather bags, sleeping bags, tents and the like, and the zipper mainly comprises paired mutually-engageable zipper teeth and sewn cloth belts at two sides for use; the types of the slide fastener can be roughly classified into a metal slide fastener, a nylon slide fastener and a plastic steel slide fastener according to the material of the zipper teeth. Although the zipper has the advantage of convenient use, the zipper has the defect of being limited to be linear in processing or using occasions, namely, the zipper is difficult to form if the zipper is required to be processed by sewing a curve or an arc; especially metal and plastic steel zippers, because the zipper teeth are shaped and the bending and stretching degrees are limited, the defects that the zippers and clothes are uneven and are arched outwards are easy to appear after processing. Aiming at the defect, the traditional technology is that when the zipper is sewn, a plurality of gaps are cut on zipper cloth belts on two sides of the zipper by scissors so as to increase the elongation of the zipper belts; in the prior art, a special weaving technology is adopted to increase the scalability of a zipper strip. Chinese patent No. 01223244.0 entitled "improvement of fastener tape" discloses "an improvement of fastener tape including a long continuous element and a tape connected to one side, a non-tape-sewn portion of the tape being knitted with a stretch yarn, which can be stretched and expanded. Chinese patent No. 200410002476.5 entitled "fastener tape" discloses a fastener tape "having a positive wrinkle state after fastener elements are mounted in a state where the fastener element fixing edge portion is recessed and curved with a main body slightly undulating," after being woven or knitted outside a core thread in one fastener element fixing edge portion and at least part of constituent yarns extending in the warp direction adjacent thereto have a higher elongation recovery rate than all other constituent yarns and core threads extending in the warp direction. Thus, a woven or knitted fastener stringer "capable of securing the straightness after the fastener tape is sewn to the target clothes can be formed. The zipper belt knitting machine in the prior art mainly comprises a yarn guide device, a knitting device, a driving device and a dragging device, and the improvement on the yarn guide device and the knitting device can manufacture a novel zipper strip, but the structure is complex and the modification cost is large.

The zipper belt manufactured by the zipper belt knitting machine comprises one side for mounting zipper teeth and the other side for sewing, wherein the other side for sewing the zipper belt is wavy. The invention also discloses a dragging wheel with a conical surface, which can apply progressive tensile force to a zipper belt simultaneously in the process of dragging the zipper belt, so that the zipper belt generates a wave wrinkle effect, when the zipper with a wavy sewing edge is sewn on target clothes, although the zipper can absorb part of shrinkage generated in sewing so that the sewn zipper is smoother than the conventional zipper, because the weaving threads of one side of the whole zipper belt, which is provided with the zipper teeth, and the other side of the zipper belt, which is sewn, are equal, the problem of shrinkage size required by the wavy zipper belt and sewing is not substantially solved, the outward bulging amplitude of the shrinkage size required by sewing is reduced only in a balanced manner due to the wavy shape after the zipper belt and cloth are sewn, namely, the final zipper belt is bulged instead of being locally large but is balanced to be slightly bulged at multiple positions on the whole, the problem that the zipper belt is arched after being knitted due to sewing shrinkage can not be solved by effectively knitting the traditional zipper belt knitting machine.
