摘要
Press rollers (102a) for being pressed respectively against wires are provided on an upper side of the wires-while length-measuring rollers (101) for respectively contacting the wires are provided on a lower side of the wires. A number of revolutions of each length-measuring roller is detected by an encoder (101e), and an amount of actual feed of each wire is detected in accordance with its revolution number, and a pulse signal, representing its detection value, is sent to a comparison processing portion of a controller. In this comparison processing portion (Cp), the amount of actual feed of each wire, detected by the encoder, is compared with a predetermined feed amount of a feed roller (117) beforehand given as an instruction to the processing portion, and if there is any difference between the two, an instruction is given to a servo amplifier (Am), and the servo amplifier sends an instruction to a servo motor (M) for driving the feed roller so as to rotate the servo motor in a normal or a reverse direction in accordance with this difference.
