DEFINITION

Classification: 72/241.8

Means to apply bending moment to roller or back-up roll:

(under subclass 241.4) Subject matter wherein the back-up is also a roller, and including means to apply to either the deforming roller or the back-up roll or a torque about an axis intersecting that roller at a right angle.

(1) Note. The purpose of torque application herein is generally to maintain the straightness of the deforming roller, rather than to stress the roller to which torque is applied.
