ABSTRACT:
A programmable sewing machine that has a work holder and X-Y actuators to move the work holder about on the bed of the machine is provided with a clamping structure to grasp a workpiece to move it about to form a programmed pattern of stitches in it. The clamping structure includes a clamp and a first quick-release connector to connect the clamp to a clamp foot on the work holder, and it also includes a cloth plate and a second quick-release connector to connect the cloth plate to the work holder under the clamp so that both the clamp and the cloth plate are firmly held by the work holder to move in unison but are both quickly releasable from the work holder to be easily replaced.
