ABSTRACT:
An apparatus for manufacturing a continuous slide fastener stringer chain including space portions devoid of coupling elements at longitudinal intervals. The apparatus comprises feed rollers for continuously feeding a pair of continuous stringer tapes, in synchronism with a sewing machine, to a sewing area in the sewing machine, a stationary guide member having a longitudinal channel for the passage of a pair of interengaged rows of coupling elements, and a toothed wheel projecting into the guide channel and rotatable for intermittently feeding the coupling elements in synchronism with the sewing machine to the sewing area. A cutter assembly is disposed between the sewing area and the toothed wheel for cutting off a length of coupling elements then being sewn from the interengaged rows of continuous coupling elements each time the latter stops moving.
