Abstract
An easily installed and disassembled web transducer device for measuring and monitoring the tension in a continuously moving web as it moves over a tensioning roller. The transducer device comprises a cantilever mounted strain beam with attached strain gauges at the beam flex points and formed at its free end with a cup-shaped coupling receptacle having an open outer end enclosing and supporting one end of a support shaft for the web tensioning roller by a self-aligning bearing retained in place in the bore of the coupling receptable by a retaining ring snap locked in an annular groove in the receptacle bore. A spring washer in the coupling receptacle bore is biased between the closed inner end thereof and the bearing to continuously yieldingly urge the latter toward axially abutting engagement with the retainer ring.
