Description

In slide fastener, form the method for no sprocket unitary space section

Thereby the sprocket unit that the present invention relates to except that uncoupling on a kind of slide fastener made of synthetic resin top forms no sprocket unitary space section on slide fastener, and this slide fastener comprises the intermeshing discrete coupling sprocket of row unit, two on the edge in opposite directions that is installed on a pair of slide fastener tail band.

Prior art forms the method for no sprocket unitary space section on the slide fastener with synthetic resin coupling sprocket unit, for example announce in 55-109410 number in the still uncensored utility model of Japan and disclose to some extent.In this still unexamined patent, form by following steps in the method that forms the space segment that does not have coupling sprocket unit on the slide fastener: slide fastener is placed on the mould, this mould has a through hole that equals the sprocket cell width in centre, on the side, there is two grades drift to fall from top position towards the head end of coupling sprocket unit, with this head end of blanking, then drift falls with the Sheet Metal Forming Technology process again the pin that is cut open remaining on the zipper strip is removed.

Yet, the formation method of above-mentioned no sprocket unitary space section exists some shortcomings: since drift be by whereaboutss go blanking be coupled sprocket unit header end and once more the whereabouts catch and remove the pin that has cut under remaining with the impact process process, the taeniae fuse of zipper strip is easy to impaired, the time can cause slide fastener fracture, and need could disposable blanking and remove the pin of incision with powerful impulse force.

The objective of the invention is to overcome above-mentioned shortcoming, a kind of method that forms no sprocket unitary space section on slide fastener is provided, can remove coupling sprocket unit effectively and not damage zipper strip with less power thus.

First aspect of the present invention is to provide the method that forms no sprocket unitary space section on slide fastener, and this method is made up of the following step:

On the space segment of slide fastener,, with cutting knife a pin of the forked pin of each head end and coupling sprocket unit, unit is separated again with the head end of the intermeshing discrete coupling sprocket of drift blanking unit with sprocket unit;

Eject rod from cutting a side above the steering handle coupling sprocket unit header end vertical with the zipper strip surface pushed to one, thereby another pin and coupling sprocket unit header end are removed from zipper strip, with the persistence pin of the incision on zipper strip of clip, pull out and remove the pin of incision again along the direction vertical with the zipper strip surface.

Second aspect of the present invention is, on removing zipper strip in the pin of remaining incision, provide another kind of method to form no unitary space section on the slide fastener, this method is made up of following steps: only clamp the pin of the incision of space segment both side ends with clip, in order to pull out and to remove the pin of the incision of both side ends along the direction vertical with the zipper strip surface; With a rolling cutter and a space segment is guided to the rot of rolling cutter again, the pin that cuts is pruned and removed the pin of the incision under remaining from zipper strip.

According to the present invention, the head end of coupling sprocket unit is removed in the different process process respectively with the pin that has cut, and then, the head end of coupling unit and the pin of incision are drawn out respectively along the rightabout with the coupling unit embedding zipper strip that will cast.So in the method, the head end of the sprocket unit that is coupled and the pin of incision only need less power just can be removed and be unlikely the damage zipper strip like a cork or cause the slide fastener fracture, thus and the space segment of the coupling of formation nothing effectively sprocket unit.

When removing the pin of incision, because just removed with a rolling cutter and cylinder after formerly the pin of the incision of space segment both side ends being removed as the pin of the incision of major part, the pin of incision can be removed effectively and need not accurately to regulate rolling cutter and cylinder nor can damage remaining coupling sprocket unit.
