Tends battery of combination lasting and molding machines that mold rubber or plastic outsoles onto fabric, leather, or plastic uppers to make shoes: Positions upper over last with heel centered and even margin of upper around last sole, pulls string in hem tight around sole of last, and ties knot to keep it from slipping. Stretches and hooks upper over pins protruding from heel and instep of last, using claw-tipped end of lasting tool, to hold upper in place during molding.
