ABSTRACT:
A workpiece guide for separately guiding, aligning and removing the curled edges of superposed layers of fabric to be joined by seaming in a sewing machine. The guide includes a plurality of spaced and vertically aligned plate elements forming passages therebetween for the fabric layers. The leading edges of the plate elements have a curved profile and adjacent the sewing axis these profiles are formed to extend in the direction of the sewing zone and define recesses with a configuration of bulbous outline. The edges of the plate elements forming the entrance to the recesses are tapered in the direction of their respective passages and are effective in engaging the pieces of fabric to complete the unrolling and straightening of the fabric edges as they enter their respective passage.
