ABSTRACT:
In sewing work for attaching slide fastener chains to fabric or leather articles, a device for controlling the traveling velocity of the fastener chain is provided, comprising a pair of upper and lower cantilever members supported by a supporting member on the table of a sewing machine. The lower cantilever is fixed to form a space between its under side and the table surface, while the upper cantilever is movable toward and apart from the lower cantilever. A suitable frictional resistance is imparted to the fastener chain traveling between the two cantilevers when the upper, movable cantilever is laid on the lower, fixed cantilever. The movement of the upper cantilever is linked to the raising and lowering mechanism of the presser foot of the sewing machine. This device serves to keep the traveling fastener chain from puckering or waving.
