ABSTRACT:
In a web reeling machine such as the reeling portion of a paper machine the successful introduction of a fresh reel bar to maintain the continuity of the reeling operation is dependent upon turn-up of the web onto the rotating reel bar followed by build-up of a roll on the reel. The end of a bifurcated fiber optic cable is positioned adjacent the jaw clamps that retain the stationary end bearings of the reel bar so as to provide an indication of the occurrence of successful turn-up by detecting a persevering change in the clamp/bearing relationship due to roll growth. The other end of the bifurcated cable is connected to an light emitter and a light detector. The light emitter generates a light signal along the bifurcated fiber optic cable towards a light guide path in a jaw clamp so that the light signal passes through the light guide path. When the jaw clamp moves, the light guide path moves and the jaw clamp reflects the light signal back toward the bifurcated fiber optic cable which transmits the reflected signal to a light detector which detects the change in reel bar location due to roll growth. The system can tolerate motion inconsistencies caused by reel bar bounce, due to a rough turn-up of the web.
