Abstract (en)
[origin: EP0012992A1] 1. Wire drawing machine with a plurality of successive drawing dies (F1 ... Fn) with which force measuring means (S1 ... Sn) are associated for emitting signals proportional to the conversion forces exerted by the wire on the drawing dies (F1 ... Fn), the wire being drawn from each drawing die (F1 ... Fn) by means of a drawing disk (C1 ... Cn) and conveyed to a following drawing die (F1 ... Fn), if provided, one drawing die being driven at a determined circumferential velocity and all other drawing dies by torque-controlled actuating means, characterized in that the regulating variable (TCn ) for each torque-controlled actuating means (Mn ) of a drawing disk (Cn ) is formed proportional to the conversion force (Tn ) of the associated drawing die (Fn ) plus the predetermined counter-draw before said drawing die (Fn ) minus the predetermined counter-drawn (RTn ) after said drawing disk (Cn ), [TCn =Tn +RTn-1 -RTn ].
