Abstract
Disclosed is an improved system for annealing strand of the type comprising at least two sheaves across which the strand passes and becomes electrically annealed, the improvement comprising a first flange member, a second flange member concentric with the first flange member and adjacent thereto, a wide annealing band positioned between the first and second flange members and forming the bottom of a sheave groove, and means for guiding the strand being annealed traversely across a traverse zone of the band to increase longevity of the band while substantially eliminating detrimental arcing by providing an insulating air gap between the strand and either of the flange members.
Claims18
In a system for annealing strand at high speed of the type comprising at least two sheaves across which said strand passes and becomes electrically annealed, the improvement comprising.
- (a) a first flange member;
- (b) a second flange member concentric with said first flange member and adjacent thereto;
- (c) a hardened annealing band positioned between said first and second flange members and forming the bottom of a sheave groove;
- and
- (d) means for guiding said strand along a predetermined traverse zone on the surface of said band.
A method for annealing strand traveling at high speed across an annealing sheave comprising the steps of:
- (a) providing a wide hardened band between the flanges of said sheave;
- and
- (b) guiding said strand repeatedly back and forth laterally along a predetermined traverse zone on the surface of said band and longitudinally concentric therewith.
