Abstract
A web passing around a drum or other countersurface is engaged by a working roll which is bendable along its length to conform to the countersurface and thereby provide uniform contact with the web. The working roller is supplied by one or more force transmitting elements which are also bendable in their lengths and which can include a bed in which the force transmitting roll is received. The bed is urged by hydraulic pistons or a liquid expandable tube, braced against a nonbendable support, in the direction of the working roll.
