Abstract
A method and device for drawing steel wire (12) through draft of multiple dies (32, 14') at several or all die positions (16'-24', 16'-24') of a wire drawing machine (30,40) to provide an increased reduction in cross area per die position (16'-24', 16'-24') without the excessive heat build up and die wear previously associated therewith. Also, a novel die (32) is disclosed with lubrication grooves (34) across the face (36) of the die casing (31) to permit liquid lubricant to reach the die/wire interface.
