FIELD: equipment for drawing wire, namely multiple drum type drawing benches operating with countertension without sliding. SUBSTANCE: drawing bench includes row of successive drawing dies. Traction drawing drums are mounted on mutually parallel double-support driving shafts in accordance with drawing dies. Drawing drums have working surfaces in the form of truncated cones. Each drawing die is arranged in plane of large base of cone working surface of respective traction drum. Working surfaces of even and odd (according to drawing order) drawing drums have reciprocal conicities. EFFECT: enhanced efficiency of multiple drawing benches due to increased speed values of drawing process, simplified design of drawing bench, lowered material consumption of frame of drawing bench. 3 cl, 3 dwg
