ABSTRACT:
A single carriage of the drawing apparatus for pulling a continuous metal workpiece through a drawing die is displaceable back and forth by a linear electronic motor drive. A coil forms a supply upstream of the die which can pay off a length of the workpiece to form a loop adapted to be drawn through the die without tensioning it against the coil.
