ABSTRACT:
A convertible web tension transducer and a roll assembly including two such transducers in which each transducer includes a coupling supported by a pair of resilient beams from a support member through a self-aligning bearing permitting pivotal movement of the coupling relative to the support member in any direction normal to a roll axis of the transducer and the roll assembly and being provided with a pivot pin arrangement to prevent relative rotation of the coupling and support member when a stationary shaft supporting a live roll is supported by the couplings of the transducers, the pivot pin arrangement including a pivot pin which may be omitted from the transducer when a live shaft or roll is supported by the couplings of the two transducers with a consequent requirement for relative rotation of the coupling and support member, about the roll axis, to be permitted.
