ABSTRACT:
A web tension monitor in which the tension of a moving web passing over a guide roll is monitored by a sensing device positioned upon a cantilever-mounted support which is coupled to a shaft which carries the roll. Forces applied to the roll by the tensioned web passing over it are coupled to a fixed frame through the cantilever-mounted support by means of a pair of concentric rings between which bearing balls are disposed in confronting openings formed in both members at diametrically opposed points. Misalignment and expansion of machine components can be tolerated to a large degree without causing pre-loading of the sensing device.
