| 摘要 | PURPOSE:To provide a tension twisted wire which is always stble from start to stop in drawing and twisting with a multi-wire drawing mill and a puncher type wire twisting machine by setting the circumferential speed of the final capstan of the wire drawing mill at specific relations respectively at low and high speeds with respect to the take-off speed of the wire twisting machine. CONSTITUTION:Multiple wire rods 1 are drawn by dies 16 as cpastans 18 of a wire drawing mill 12 revolve. The drawn wires pass through tension control rolls 38 and a mouthpiece 26 and enter a wire twisting machine 14 where the twisted wire is taken up on a take-up drum 36 by capstans 30. The signal Sax obtd. by multiplying the rotating speed signal Sx of the tension control roll 38 by a proportional constant (a) and a specified bias value A are added in an arithmetic circuit. The value Sy thereof is put into a driving circuit 48 which controls a motor 40 to rotate the final capstans 18A. However, the bias value SB is further added to drive said capstans to improve wire twisting at the low speed of | ||||||
