Method for heat treating wire or the like

Abstract

Abstract VARIOUS ARRANGMENTS AND METHODS ARE DESCRIBED FOR ELECTRICALLY HEATING A RAPIDLY TRAVELING WIRE AS IT PROCEEDS ALONG A HELICAL PATH AROUND A GUIDE ROLL. A PRESSURE ROLL STRUCTURE COOPERATES WITH THE GUIDE ROLL TO MAINTAIN ADJACENT TURNS OF THE HELIX IN INTIMATE CONTACT WHERE REQUIRED OR IN CONTACT WITH ITSELF AND THE GUIDE ROLL. ONE, OR BOTH, OR NEITHER, OF THE ROLL MEMBERS MAY HAVE AT LEAST AN ELECTRICALLY CONDUCTIVE SURFACE FOR PROVIDING A PATH FOR BRIDGING CURRENTS BETWEEN THE HELICAL TURNS OF THE WIRE. THE PRESSURE ROLL STURCTURE MAY BE SEGMENTED AND FLOATINGLY MOUNTED. THE INDUCTION COIL MAY BE NON-UNIFORM IN DIAMETER TO PROVIDE CONTROL OF THE HEAT GENERATED OVER DIFFERENT PORTIONS OF THE WIRE HELIX.
