ABSTRACT:
A multi-rail tension equalizer for a reel-to-reel web transfer system. In the web transfer system, the feed stock material is released from one reel containing multiple attached rails. The rails are split using an etching process. The multi-rail tension equalizer has multiple take-up reels. Each take-up reel corresponds to a rail of material. The tension in the take-up rails is equalized by controlling the take-up rate independently for each reel. The reels are mounted on concentric drive shafts each of which are powered by an independently controlled motor.
