Abstract

PURPOSE:To provide a product which is uniform in width and thickness through exchange of a bobbin without stopping a rolling machine by a method wherein when a full bobbin is exchanged with an empty bobbin, a wire rod between a bobbin and a guide roll is pressed by a wire press member, and the wire rod is locked to a lock member. CONSTITUTION:When a wire rod W fed from a rolling machine is wound around a bobbin B and the bobbin is brought into a full state, a guide member 36 is moved aside to a position, there is no hindrance to exchange a bobbin, through rotation of a motor 28 for separation. A guide roll 18 is axially moved to a position, where it approaches the flange F of the bobbin B, by means of a ball screw mechanism 21. A turret 17 is then rotated in a 180 deg. arc with the aid of a motor for rotation, and the position of a full bobbin B is exchanged with that of an empty bobbin B. In this case, through drive of a rotary actuator 40, the wire rod between a guide roll 18 and the full bobbin B is pressed externally of the flange F of the bobbin by means of a wire press member 39. The wire rod W is locked by means of a lock member 38 for the empty bobbin B to wind the wire rod W around the empty bobbin B.
