Abstract
A device for supporting and guiding a folded workpiece to the stitching needle of a sewing machine by advancing the same between a pair of cylindrical members mounted on the machine for rotation in opposite directions. Each of the cylindrical members is provided with circumferential grooves on their peripheral surfaces with the grooves of each being in general alignment with those of the other. The configuration of the grooves in combination with the spacing between the cylindrical members causes the folded workpiece being advanced therebetween, to become deformed to the extent where portions thereof enter the grooves to effectively support its weight while accurately guiding it along the level of its intended path of travel.
