Abstract
A device for use with sewing machines for transport of work pieces. The transport device removes finished workpieces from a sewing area and feeds the workpieces to a transfer point at which the end section of the work piece is held with little force to allow the workpiece to be gripped by a stacking element. The arrangement allows for the next workpiece to be inserted into the sewing area simultaneous with the removal of the finished workpiece. The transport device includes a swivelable arm carrying a driven conveyor belt. The arm may be swivelled upward once the front section of the work piece has been moved underneath the swivelling axis of the arm, so that a new workpiece can be inserted. The conveyor belt can be arrested before the end section of the workpiece passes through. The conveyor belt contact pressure can be reduced such that the work piece can be pulled out easily by a stacker.
