FIELD: process engineering.SUBSTANCE: proposed device comprises drums articulated with the drive and run-around rolls to press every wire to the drum and arranged to move for adjustment of drawing force. Compact arrangement between drawing dies, increase in torque transmitted by drums and availability of servicing space are ensured by arranging drums 1 are arranged in circle perpendicular to wire displacement direction and fitted on common flexible shaft 4, both ends of which being connected to the drive output shaft ends. Run-around rolls 8 serve to press every wire 9 to the drum and arranged to move for adjustment of drawing force. One or several annular grooves are made on drum surface, each accommodating one wire. Note here that run-around rolls for said wire are fitted into groove by their periphery.EFFECT: compact design, simplified servicing.2 dwg |
