METHOD AND APPARATUS FOR MACHINING WIRES E.G. ROLLED WIRE

摘要

Wire finishing apparatus wherein the leader of a supply of convoluted wire is threaded through a combined straightening and calibrating unit and into the range of feed rolls in a shaving unit. The rolls of the calibrating unit are moved apart during such threading but engage and calibrate the wire when the latter is pulled by the feed rolls so that it passes through the revolving shaving head and the leader reaches and is connected to the drum of a collecting unit. The drum is thereupon started to withdraw the wire at a higher speed whereby an overrunning clutch allows the feed rolls to rotate at the speed which is determined by the motor which rotates the drum. The rolls of the calibrating unit are adjusted to furnish a more pronounced calibrating action when the wire begins to advance at the higher speed.
