A pivoting twin roller for feeding a material to a sewing machine is disclosed. The twin rollers grip the material with serrated rollers, which rotate at the same rate for uniformly moving the material relative the sewing machine. The twin rollers press down on the material with equal force due to the central pivot point, which improves the feed of the material.
