ABSTRACT:
A moving web tension monitoring apparatus of easily fabricated, relatively inexpensive and easily assembled construction comprises a cantilever mounted strain beam element coupled at the flexurable end thereof through a self-aligning bearing to one end of the support shaft for the web supporting guide roll by a coupling member removably fastened to the shaft end and having a multiply axially split expandable tubular collar portion projecting endwise from the shaft end into the self-aligning bearing and expanded by a locking member forcibly inserted into the collar portion to expand and tightly lock it to the bearing. The self-aligning bearing preferably is of the roller bearing type having barrel shaped roller elements, and the strain beam means preferably is of the twin beam type having a pair of vertically spaced, parallel beam members formed by drilling out the core of a metal block member from which the sensor member of the transducer is fabricated.
