Abstract (en)
A non-siip wire drawing machine with a reduced number of dancers is provided. The wire drawing machine comprises: a first wire drawing die for reducing a diameter of a metal wire passing therethrough, thereby drawing the metal wire; a back tension control unit that controls a first back tension of the metal wire passing through the first wire drawing die; a first capstan that pulls the metal wire passing through the first wire drawing die at a first front tension through the first wire drawing die in a non-slip manner; a first front tension measuring unit that measures the first front tension; a first capstan control unit that controls a rotation torque of the first capstan based on the measured first front tension; and a winding unit that winds up the drawn metal wire.
