Abstract
A throat plate for a sewing machine having an above the bed feeding system, which throat plate provides for minimum drag on the work material. The throat plate is fashioned with a relief in which is situated a feed plate supported upon ball bearings for minimum friction, which feed plate is resiliently loaded to a central position. The throat plate is designed so that a presser foot of the above the bed feeding system will not impinge upon the movable feed plate and the feeding foot will impinge only upon the movable feed plate. Thus, work material captured between the feeding foot and the movable feed plate is not subjected to the usual drag from a stationary throat plate and, upon being released by the feeding foot, the movable feed plate returns to a starting position.
