ABSTRACT:
The apparatus puts at least one metal beginning piece on a cotinuous slide fastener chain made by connecting a plurality of slide fasteners each with beginning piece regions prepared for receiving a metal beginning piece and with the first slide fastener coupling members bounding the beginning piece regions of the slide fasteners. The opened slide fastener chain is moveable or advanceable stepwise by the apparatus. The apparatus comprises a tool block which is slidable on a plurality of guide rods oriented substantially in the feed direction of the slide fastener chain, two contacting elements associated with both halves of the open slide fastener chain mounted on the tool block which are pivotable about contacting element pivot axes substantially parallel to the guide rods, two clamp jaws associated with the contacting elements mounted on the tool block which similarly pivot about clamp jaw pivot axes substantially parallel to the guide rods, a control member for operation of the clamp jaws which has at least one control surface extending substantially in the longitudinal direction of the guide rods which engages at least one opposing control surface on the clamp jaws and a beginning piece mounting tool.
