Thus, the pattern, writing or marks in the zipper are coupled or symmetric.

Description

The manufacture method of slide fastener figure alignment

The present invention relates to a kind of processing and manufacturing of slide fastener, the combined method of particularly a kind of slide fastener elements manufacturing and installation.

The figure that disposes, printed words or mark on the general slide fastener, be to be divided into three kinds: common required pattern, printed words or mark, during the strap braiding, inweave continuous strap with dobby machine, first card jacquard loom, or before the zipper sprocket deploying invests continuous strap, place on the continuous strap with printing or staining method, but because of above-mentioned three kinds of modes required figure, printed words or mark are put on completed zipper cloth, on processing procedure, will be had following defective:

1. because two zipper cloths are distinctly to make, zipper cloth is in manufacture process, Chang Yiyin longitude and latitude braiding difference, conveying machinery speed or cylinder wearing and tearing, pulling force difference, make the intensity of zipper cloth also inequality, by contrast, no matter easily make on the zipper cloth, can't match each other with figure, printed words or the mark of printing or dyeing or weaving method, uneven, as shown in Figure 1.

2. because the slide fastener that oneself finishes has zipper sprocket inboard the attaching of its zipper cloth, so though its required figure, printed words or mark might stamp or dye up, but, print off or figure, printed words or the mark that gets on that dye is difficult to complete, easily produce damaged and flaw, relatively, destroy the aesthetic feeling of slide fastener especially.

At above-mentioned disappearance, once the someone proposed a kind of method of making zip strip, and as Fig. 2, its manufacturing step is:

A. embarking on journey with arranged spaced two row is marked on the length direction of continuous strap, and its each pattern matches each other;

B. the relation of keeping to the side with the limit is presented strap relatively continuously, makes it to join attached station towards sprocket;

C. during presenting relative continuous strap, check corresponding one-tenth row labels;

D. control presenting of relative strap so that become row labels to confirm on inspection to be in alignment with each other accordingly, then strap continues to present, confirm on inspection not to be in alignment with each other in corresponding one-tenth row labels, then prevent presenting of guide's strap, be in alignment with each other thereby band draws corresponding one-tenth row labels;

E. join attached station at sprocket, join Annex II and arrange vertical inner edge of continuous sprocket, be in alignment with each other and make into row labels at relative strap.

Above-mentioned manufacture method, to the eye, figure, printed words, mark on the continuous cloth is rough to match each other though can make, and in the actual fabrication process, still has following drawback.

1. set one-tenth row labels confirms not to be in alignment with each other through the electric eye inspection on continuous strap; then need machine is stopped action, be adjusted to row labels and align mutually, begin to continue action again; fail to be in alignment with each other as in manufacturing process, running into into row labels again; need to shut down once more to adjust, will notice that at every moment embarking on journey on the continuous strap marks whether alignment, as fail to align; after just must shutting down the adjustment alignment; continue operation once more, both bothered, again waste.

2. utilize two delivery wheel branches to both sides guiding to carry continuous strap, then continuous strap is in course of conveying, the transporting velocity of Yi Yin both sides delivery wheel differs, add to utilize electric eye to control to embark on journey on the continuous strap and mark whether alignment, as fail to align, then need to adjust control respectively, will expend the more time (as Fig. 3) in the operation.

Since two continuous straps when sewing up, need and to sew up behind its label alignment of embarking on journey, and these two continuous straps are to form with separately weaving through the weft yarn braider of different machineries, it produced draws, the tension force difference, and its top figure, printed words or the formed error of mark have between 85 80 percent to percent approximately, see that still drawing halves degree of matching differs.

This scheme sewing sprocket as with during electric-motor drive, when the power supply value not for the moment, the weight that can cause the pin of sewing to sew up differs, and zipper cloth is had pull situation (be commonly called as eat cloth differ), can't make and maintain flatness on the zipper cloth belt.

5. the roller of this scheme is to utilize general motor drives, makes roller pulling force, speed difference, easily causes zipper cloth belt sewing difference, needs often to adjust roller; In addition, when roller uses long afterwards, there are wearing and tearing on the surface, and its straight circularity not enough (as Fig. 4) will often be changed another new roller, is again an expenditure greatly on the cost, does not meet economic benefit.

Be (whether to embark on journey label alignment as utilizing electric eye to control on it, continue action after the adjustment again, bother time-consumingly again, easily form substandard products again for solving the disadvantages that above-mentioned zipper cloth belt produces; Slide fastener unit price height; Zipper cloth belt is being met the phenomenon of pullling of sewing machine seam; The normal roller etc. of changing), often perplexed by the user.

The objective of the invention is to provide a kind of manufacture method of improved slide fastener figure alignment, it can eliminate classical production process because of delivery wheel intensity, pulling force difference or intensity difference, influence disappearances such as slide fastener figure degree of registration, can obtain quicker, make figure, printed words or mark more can match each other, have more practicality and economy.

The objective of the invention is to realize by following method.A kind of manufacture method of slide fastener figure alignment, it comprises the following steps:

1. continuously installing figure, printed words or mark on the cloth: be to weave the required figure of embroidery, printed words or mark in the lump in the continuous cloth surface printing of slide fastener or dyeing or with continuous cloth;

2. cutting: the cutting knife through being installed in sewing machine the place ahead or form two slide fastener selvedges with cutting in the middle of the continuous cloth with the laser cutting cutter;

3. stitching sprocket: cut in the middle of the rear zipper selvedge sewing sprocket immediately, and sew up the power that drags, sprocket is sewn in the middle of two slide fastener selvedges on the inboard, match each other with the figure on the seasonal slide fastener, printed words or mark by sewing machine.

The present invention is cutting with cutting knife in the middle of the cloth continuously, form two slide fastener selvedges, and the middle sewing sprocket immediately of two slide fastener selvedges after cutting, and the mat sewing machine is sewed up the power that drags, sprocket is sewn on the middle inboard of two slide fastener selvedges, make the figure on the slide fastener simultaneously, printed words or mark be the reason fabrication errors not, the not equal factor of intensity and conveying machinery speed pulling force, formation mismatches, asymmetric defective is eliminated the trouble that traditional time-consuming adjustment is controlled, and does not also need often to change accessory, thereby zipper cloth is kept outside the original effectiveness, and processing procedure is quicker, makes manufacture method provided by the invention have more practicality, and meets principle of economic benefit.

Below with reference to accompanying drawing invention is described in further detail.
