Abstract

The invention discloses a method for producing a zipper. The steps for rubberizing and sleeving a pin case block (6) are as follows: firstly, punching a hole (4) at a position close to a sprocket (3) of a rubberized fabric (2) while attaching the rubberized fabric (2) by a chain cotton tape (1); secondly, punching a mounting hole (5) at a position close to the pin case block (6) to be mounted in the rubberized fabric (2); and finally, mounting the pin case block (6) by the mounting hole (5) and cutting off the chain cotton tape (1) along the lower part of the pin case block (6). By adopting the method, the hole (4) is punched at a position close to the sprocket (3) while rubberizing, so that the rubberized fabric (2) cannot cover the sprocket (3) which cannot be damaged by rubberizing, the quality for manufactured zipper can be improved and the defective percentage of the zipper can be reduced; and the mounting hole (5) is punched at the position close to the pin case block (6) to be mounted in the rubberized fabric (2), so the pin case block (6) is mounted without firstly cutting off the chain cotton tape (1). The method is beneficial to improving the production efficiency of the zipper.

Description

The manufacture method of slide fastener

Technical field

The utility model relates to a kind of manufacture method of slide fastener, particularly a kind of sprocket, convenient manufacture method that tip box block slide fastener is installed can not damaged.

Background technology

Traditional slide fastener production stage comprises: (1) is planting sprocket on the chain strap; (2) rubberized fabric; (3) cut off the chain strap; (4) tip box block is installed.

As above-mentioned step, in traditional slide fastener production method, after above the chain strap, planting sprocket, follow-up work is exactly rubberized fabric, to strengthen the intensity at this position, still, owing to need the place of rubberized fabric and sprocket to combine, adhesive plaster usually covers sprocket, and like this, sprocket will damage owing to rubberizing.In addition, in the prior art, usually be after the chain strap is cut off, tip box block to be installed again, such mounting means is unfavorable for the mechanization production of slide fastener.

Summary of the invention

The purpose of this invention is to provide a kind of slide fastener production method of damaging sprocket rubberizing can be prevented the time and helping improving the production efficiency of slide fastener.

For reaching above-mentioned goal of the invention technical scheme of the present invention be: a kind of manufacture method of slide fastener, the step of its rubberizing, suit tip box block is as follows:

At first, in chain strap rubberized fabric, use puncher, make adhesive plaster not cover sprocket, adhesive plaster is posted in the place punching of adhesive plaster near sprocket;

Then, the position that tip box block is installed near desire at adhesive plaster is towards establishing installing hole, and the size of installing hole is advisable to be fit to that tip box block is installed;

At last, tip box block is installed, after tip box block installs, along the below cut-out chain strap of tip box block by installing hole.

Described installing hole is an elongated hole.

The invention has the beneficial effects as follows: the present invention is in rubberizing, and the place punching near sprocket makes adhesive plaster be unlikely to cover sprocket, makes sprocket can not damage because of rubberizing, improves the quality of zipper fabrication, the defect rate of less slide fastener; The position that tip box block is installed near desire at adhesive plaster is towards establishing installing hole, and the chain strap just need not cut off in advance like this, and tip box block is installed again, helps improving the efficient that slide fastener is produced.

Description of drawings

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

Fig. 1 is the schematic diagram of manufacture method rubberizing of the present invention, punching.

Fig. 2 utilizes rubberizing of the present invention, punching back that the schematic diagram of tip box block is installed.

The specific embodiment

A kind of manufacture method of slide fastener as shown in Figure 1, is being planted sprocket 3 on the chain strap 1, rubberizing then, and the step of rubberizing, suit tip box block 6 is as follows:

At first, in chain strap 1 rubberized fabric 2, use puncher, make adhesive plaster 2 not cover sprocket 3, adhesive plaster 2 is posted in the place punching 4 of adhesive plaster 2 near sprocket 3.Like this, adhesive plaster 2 is unlikely to cover sprocket 3, makes sprocket 3 can not damage because of rubberizing, improves the quality of zipper fabrication.

Then, the position that tip box block 6 is installed near desire at adhesive plaster 2 is towards establishing installing hole 5, and the size of installing hole 5 is advisable to be fit to that tip box block 6 is installed.

At last, as shown in Figure 2, tip box block 6 is installed by installing hole 5, after tip box block 6 installed, along the below cut-out chain strap 1 of tip box block 6, chain strap 1 just need not cut off in advance, tip box block 6 is installed again, is helped mechanization production, improve the efficient that slide fastener is produced.

The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.

Claims

1. the manufacture method of a slide fastener is characterized in that, the step of rubberizing, suit tip box block is as follows:

At first, in chain strap (1) rubberized fabric, use puncher, make adhesive plaster (2) not cover sprocket (3), adhesive plaster (2) is posted in the place punching (4) of adhesive plaster (2) near sprocket (3);

Then, the position that tip box block (6) is installed near desire at adhesive plaster (2) is towards establishing installing hole (5), and the size of installing hole (5) is advisable to be fit to that tip box block (6) is installed;

At last, tip box block (6) is installed, after tip box block (6) installs, along the below cut-out chain strap (1) of tip box block (6) by installing hole (5).

2. the manufacture method of slide fastener according to claim 1, it is characterized in that: described installing hole (5) is an elongated hole.
