Abstract
The utility model relates to a cloth belt zipper with no centre yarn, which belongs to the zipper technical field; the aim of the utility model is to provide a metal zipper which saves a cloth belt machining procedure and equipment, has good intensity of belt ribs, uniform towing force and good smoothness when a zipper head is pulled; after zipper teeth are arranged on the belt ribs and used, the zipper teeth are uneasy to displace and deform. The utility model comprises two bars of cloth belts, the zipper teeth, the zipper head, a top stop and a lower stop; the main point lies in that the belt ribs of the zipper teeth are arranged in two bars of cloth belts; the center core yarn which is put in addition is not wrapped and woven inside the cloth belts; the cloth belts are woven by warp threads and crossing threads which can weave the cloth belt. The cloth belt zipper with no centre yarn has the advantages that: 1. the machining procedure and a knitting machine for machining the center core yarn are omitted; therefore, the manufacturing cost of the metal zipper is substantially reduced. 2. The belt ribs and the cloth belts are integrated into a whole with good intensity of belt ribs and uniform towing force; after the zipper teeth are arranged on the belt ribs and used, the zipper teeth are uneasy to displace and deform; the zipper has long life-span. 3. When the zipper head is pulled, the zipper has good smoothness.
Description
Technical field
The utility model belongs to the slide fastener technical field, and being specifically related to a kind of strap does not have middle heart yearn slide fastener.
Background technology
The band muscle of its two strap dress sprockets of existing metal zip fastener, all be to insert braiding with two middle heart yearns of braiding in addition to form, there is following disadvantage in this structure: the one, and heart yearn during it need at first weave with special braider, again the warp of middle heart yearn as the braiding strap is contained on the braider of braiding strap, is woven into strap again with other warp, parallel.So it must be with two road manufacturing procedures, two kinds of different braiders, so working (machining) efficiency is low, the processing cost height.The 2nd, the strap that is woven into as stated above, the globality of middle heart yearn and strap is poor, they the two can not organically combine, therefore, its intensity difference of band muscle of strap, pulling force is inhomogeneous, sprocket is contained in and uses the easy displacement of back sprocket, distortion on the band muscle, influences the life-span of whole piece slide fastener.The 3rd, smoothness is poor during pull head, trace it to its cause is because two SMIS linear systems are the cords that are woven into, the shape spirality, with its be woven into the band muscle after, the band muscle can exist spiral concavo-convex too, and sprocket will produce small height and parallelism error between each sprocket after being contained on the band muscle, can feel the cunning that has some setbacks when therefore, people use the slide fastener pull head.
Summary of the invention
The purpose of this utility model is not have middle heart yearn slide fastener for metal zip fastener provides a kind of strap, it can save the manufacturing procedure and the process equipment of strap, and band rigidity of soft tissues degree is good, tension uniform, sprocket is contained in and uses the back sprocket to be difficult for displacement, distortion on the band muscle, and smoothness is good during pull head.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of strap does not have middle heart yearn slide fastener, comprise two straps, sprocket, pull head is gone up and is ended, end down, its main points are the band muscle of two strap dress sprockets, do not wrap up in it and are knitted into the middle heart yearn of inserting in addition, and the band muscle is formed by warp, the parallel braiding of self braiding strap.
The utility model is not knitted into the middle heart yearn of inserting in addition because wrap up in the band muscle, the band muscle is formed by warp, the parallel braiding of self braiding strap, so it one is the braider that has omitted heart yearn in the manufacturing procedure of heart yearn in the processing and the processing, the work efficiency of therefore processing strap has obtained increasing substantially, saved the braider of heart yearn in the processing, because above reason is reduced the manufacturing cost of metal zip fastener significantly; The 2nd, band muscle and strap are organic wholes, so band rigidity of soft tissues degree is good, and tension uniform, sprocket is contained in and uses the back sprocket to be difficult for displacement, distortion on the band muscle, and the life-span of slide fastener is long.The 3rd, the band muscle does not exist spiral concavo-convex, so the pliability of strap is good; Band muscle dress sprocket position shape is smooth, does not have difference each other, so sprocket is contained on the band muscle, height difference each other, depth of parallelism difference are very little, and smoothness is good during pull head.

The specific embodiment
By Fig. 1-2 represented be the structure of existing metal zip fastener, it comprises two straps 1, sprocket 2, pull head 3 upward ends 4, ends 5 down, band muscle 6, middle heart yearn 7 usefulness parallels 9 that its band muscle 6 is inserted by other parcel weave and form.The disadvantage of its existence is described in background technology.
By Fig. 3-5 represented be an embodiment of the present utility model, it comprises two straps 10, sprocket 11, pull head 12 upward ends 13, the band muscle 15 that ends 14, two straps, 10 dress sprockets 11 is down formed by warp 16, parallel 17 braidings of self braiding strap 10.
Present embodiment is not knitted into the middle heart yearn of inserting in addition because wrap up in the band muscle 15, band muscle 15 is formed by warp 16, parallel 17 braidings of self braiding strap 10, so band muscle 15 is organic wholes with strap 10, band muscle 15 each position integral body are standardized, do not exist spiral concavo-convex, so sprocket 11 is contained on the band muscle 15, height difference each other, depth of parallelism difference are very little, can very suitable cunning when drawing pull head 12; Need not to use middle heart yearn in the present embodiment, braider of heart yearn in the manufacturing procedure of heart yearn and the processing during so it has omitted and has processed, the work efficiency of therefore processing strap 10 has obtained increasing substantially, and the equipment input obtains reducing, thereby the manufacturing cost of metal zip fastener is reduced significantly; Being with muscle 15 and strap 10 in addition is organic wholes, so band muscle 15 intensity are good, and tension uniform, sprocket 11 is contained in and uses back sprocket 11 to be difficult for displacement, distortion on the band muscle 15, and the life-span of slide fastener is long.
From present embodiment as can be seen, the utility model provides a kind of long service life for metal zip fastener; Low cost of manufacture; The pull head pulling is along sliding new technical scheme during use.
