ABSTRACT:
A fabric feed mechanism that includes a forward feed roller located forward of the stitch forming area and a rear feed roller located to the rear of the stitch forming area. The drive to the forward and rear feed rollers is synchronized such that the fabric is fed to the stitch forming instruments in a relaxed and unstretched condition. There is a independently applied downward pressure to forward and rear feed rollers and the forward feed roller is raised along with the presser foot. The front feed roller has sections that are located on opposite sides of the presser foot toe to thus ensure that the top layer of fabric is fed under the presser foot rather than riding up the front roller.
