ABSTRACT:
An auxiliary feed mechanism adapted for use with a sewing machine including a feed roller for advancing the workpiece through the work station and a mounting structure adapted to move the feed roller between two positions in one of which the feed roller is operative to aid in feeding the workpiece through the workstation and in the other of which the feed roller is rendered ineffective to transmit motive power to the workpiece. A plurality of flexible couplings drive the feed roller in timed relation to the actuation of a variable speed drive motor which is coupled in a unique electric circuit relationship with the main drive motor of the machine so as to vary the feeding rate of the feed roller in accordance with the machine cycle rate.
