ABSTRACT:
A device for tensioning material to be sewn includes a driven pull roller, a connecting plate for shifting the pull roller upwardly when the presser foot of a sewing machine is raised, and a cammed guide track and follower support for the pull roller that causes the pull roller to retract outwardly with respect to the presser foot when the pull roller is shifted upwardly. Also provided is a handle for retracting the pull roller assembly independent of the motion of the presser foot.
