A positioning device for advancing a workpiece to and orienting the same in the sewing zone of a sewing unit. The device includes a feed table having a plurality of slots upstream of the sewing zone which are disposed at an angle relative to the line of sewing. A driven endless belt is operatively associated with each slot in the feed table and are disposed so as to partially protrude their respective slot. That portion of the endless belts protruding through their respective slots are caused to engage the underside of a workpiece and are effective in advancing the same to a position in front of the sewing machine's presser foot and in close proximity with a vertical guide wall extending parallel to the line of sewing.
