ABSTRACT:
Automatic assembly for sewing flypiece to a continuous slide fastener chain includes a sewing machine, a gapping device from which the continuous chain having element-free gaps formed at regular intervals therealong is fed to the sewing machine, and a flypiece delivery system for successively retrieving individual flypieces one at a time from a stack and successively advancing to the sewing machine. The flypiece delivery system is arranged such that successive flypieces are sewn to the fastener chain virtually even with the rate at which gapped chain is delivered from the gapping device.
