Abstract
A guide mechanism for the roller presser bar of a sewing machine of the type that includes an upper surface roller feeder for imparting movement to the upper work surface and a presser foot that cooperates with the feed dog. The guide mechanism for the roller presser bar is independent of the guide mechanism for the presser foot bar. The independent guide mechanism for the roller presser bar avoids binding of the roller presser bar that occurs when a common guide mechanism is utilized for both the roller presser and the presser foot bar. The roller presser bar guide mechanism includes a pair of movable vertically aligned surfaces attached to the bar and a cooperating block attached to the sewing machine housing with a pair of adjustable guide plates.
