Abstract
In order to allow a sewing machine to continuously sew workpieces fed to it by a conveyor during periods when the conveyor is stopped for workpiece loading, drive means are provided for cyclically moving the sewing machine back and forth alongside the conveyor parallel to the direction of conveyor travel, while simultaneously driving the conveyor at twice the sewing machine's rate of travel when it moves in the direction of workpiece feed and for stopping the conveyor when the sewing machine is traveling in the opposite direction.
