PURPOSE:To perform the wire-drawing treatments of a wire rod with less operators and high productivity by winding the wire rod by a bobbin made of heat-resisting material to anneal it before setting it to a flyer device and paying off the wire rod from the bobbin through a peeling roll in performing a series of wire drawing treatments. CONSTITUTION:After charging a wire rod 2 into a heat treatment furnace to anneal it in a state of winding it up by a steel-made bobbin 1; the bobbin 1 is set to a flyer device 3, and the wire rod 2 is payed off, by pulling the wire rod 2 in the arrow-A direction with the aid of a take-out device 31, and rotating a rotational member 11, equipped with arms (a), (b), (c) to which a rubber ring 5, a peeling roll 15, and a guiding member 16 are attached respectively, in the arrow-B direction, and also rotating the roll 15 in the direction reverse to the rotating direction of member 11 by a driving motor 20. Then, after passing the peeling roll 15, the guiding member 16, and a pulley block 23 of a tension control device 22, the wire rod 2 is subjected to a series of wire drawing treatments on a continuous line by passing it through the 1st and 2nd pickling tanks 25 (a), (b), the 1st and 2nd rinsing devices 27 (a), (b), a lubrication tank 29, and a wire drawing die 30, and then the wire rod 2 is wound up by a bobbin 32. Further, the device 31 is stopped together with the member 11. |
