Abstract
A wire drawing machine comprises a wire supply unit with an unwinding bobbin for unwinding a wire, a wire drawing unit or units for drawing and reducing the diameter of the wire, and a wire winding unit for winding the drawn wire. Each wire drawing unit comprises: a dancer roller for applying back tension to the wire; a wire drawing die for reducing the diameter of the wire; and a capstan for winding and transporting the wire without slip to apply front tension to the wire. The dancer roller is linearly moved substantially in parallel to direction of wire drawing of the wire drawing die, whereby the wire drawing unit can be reduced in width. A plurality of such wire drawing units can be placed between the wire supply unit and the wire winding unit in multiple rows so as to further reduce the width of the wire drawing machine.
