ABSTRACT:
A method of forming sheaves of the type used in moving and guiding wire in wiremills. A sheet steel blank is freely rotatably carried on an arbor between two driven forming rollers and the rollers have peripheral edges which, when the rollers are forced toward the blank form an initial groove and progressively deepen the groove and spread the lips bounding the groove, while polishing and hardening the groove surfaces. The machine includes an arbor for freely rotatably holding a blank for the sheave, carriages for holding forming rollers and motor means for driving the rollers, and means for forcing the rollers into the blank which is disposed therebetween.
