Machine for the manufacture and fastening of Zipper end pieces

The invention relates to a machine for the manufacture of slide fastener end pieces from a continuous, in particular metallic tape strips and au their attachment to a machine passing plate · »pair that consists of already _s prefabricated spaced juxtaposed, yet endgliedfreien zippers"

It is ready known to produce Reißverschläß end pieces in a machine, and this in a second machine to the zippers to befestigenp this case be brought produced in the first machine end pieces in a container to said second machine, in which they S _0, via , a Rüttelraaga / zin and ^{fed along a S 1} UQrUBg to the fastening process.

nor the disadvantage that the end pieces with their Easily hooked into each other and there » with the feed of the end pieces interrupted vrirdo Ua the machine often had to fix this turned off. Furthermore, this machine must be constantly monitored to avoid defective production. Also, this means of manufacturing and fastening a relatively high mechanical effort o

In contrast, it is the task of the invention to create a machine to create the manufacture of such heat seal erid pieces and directly afterwards to the one passing through Zipper fastened and thus the above-mentioned Disadvantages eliminated.

To this end, the invention proposes that this machine a punching device, a separating device and a bending device, which sequentially connect the zippered end pieces from the supplied Baside make that the machine also a work station for attaching the finished Zipper end piece on the prepared brought up remaining zipper and that the machine also with a zipper tape for attaching

of the or "the zipper end pieces is equipped step-by-step paösend further conveying device". Such a machine has the advantage that the slide fastener Endetück each made can be immediately thereafter attached to a prepared slide fastener "It is advantageous _for when the zipper end pieces manufactured devices which Arbeite- ä station for attaching the zipper end pieces on the zippers as well as the device that gradually moves the zipper tape further on a common machine positiono '& ell, which are effective for the workpiece one after the other, are arranged »

According to a preferred embodiment, the punch «= device of the machine have a punching block, which preferably has a transverse to a guide slot for the Has provided a guide channel for the punching tool that extends through this guide base seat, the edge of the guide channel in the guide hollow designed as an Öegenmesser for the punching tool Bind ο This arrangement is advantageous because the relatively thin tape strips in the guide base seat adapted to it, the punching tool in more detail Location is fed and a good one for the punching tool

According to a further development of the invention, the machine can have a preferably production-controlled feed device for the step-by-step advancement of a predetermined length of the sand strip. It is thus ensured that prior to each production process, a corresponding piece of the tape tab ± n the machine is inserted "Optionally, this machine having a feed-1 ength the determined stop"

There is a particularly good embodiment of the invention in that the punching tool has an achaeymraetrisohen, extending almost across the width of the strip, on two adjacent Eeißversefoluß end pieces jjefenahmigungslaschen forming, preferably approximately diamond-shaped cross-section has «With this favorable execution form an opening is punched in the tape strip, whose.
