ABSTRACT:
A web tension control system includes a stationary rod and a roller attached to the rod by a flexible coupling. A bearing is attached to the inner surface of the roller. The flexible coupling is attached, at one end, to the rod, and, at a second end to the inner portion of the bearing. The inner portion of the bearing is attached to the flexible coupling. One embodiment enables the roller to pivot about a central location where the bearing is attached to the inner surface of the roller. Another embodiment provides full pivotal freedom for the roller to angularly rotate about a central location through a limited range of angular displacement.
