Abstract
A zip-fastener feeding device for an automatic sewing unit comprises an introduction device, an endless drawing means guided via a drive wheel and via deflection pulleys and a guiding device. Zip fasteners can be introduced through the introduction device by means of the drawing means by at least one guiding channel of the guiding device onto a workpiece retaining plate or a zip-fastener retainer provided in the latter and these zip fasteners can be precisely positioned there.
