PURPOSE:To shorten the arrangement time at the time of charging cutting length of wire rod into each control motor adjusting shift of a stopper and rotating speed of pressing rollers. CONSTITUTION:At the time of inputting new cutting length to an arithmetic unit 38, the position of stopper 11, the rotating speed of pressing rollers 5 and the position of shifting body 32 are operated and these values are outputted to a motor driving control circuit 37. At first, the operating value for the new position of stopper 11 is compared with the actual position signal value and the difference is transmitted to a first control motor 21. A screw rod 15 is rotated by driving the first control motor 21 and the stopper 11 is shifted to the suitable position to the cutting length. Further, the operating value for new position of the shifting body 32 is compared with the actual position signal value and the difference is transmitted to a second control motor 29. A screw rod 30 is rotated by driven the second control motor 29 and the shifting body 32 is shifted to the prescribed position. In this way, the pressing rollers 5 are intermittently driven as rotating by the rotating angle to be possible to send to bump the wire rod (a) against the stopper 11 at the new position. |
