Abstract:
1. A device mounted on a frame of a printing or laminating machine to reduce uneven nip force across a pair of deflection rollers by providing a moment loading to one roller of the pair to counteract the bending moment created by a nip force between the rollers, the one roller being rotatably supported by a journal bearing at each end thereof, the device comprising a lever mechanism for imparting translational and torsional movement to the journal bearing with respect to the frame; wherein the lever mechanism includes: a lever arm pivotable about an axle to cause the axle to move generally perpendicularly with respect to the frame when a force is applied to a first portion of the lever arm; and a connecting arm connecting between the axle and the journal bearing such that when the axle moves toward or away from the frame, the connecting arm pivots with respect to the journal bearing, imparting a torque to the journal bearing; and wherein a second portion of the lever arm disposed opposite the axle from the first portion of the lever arm contacts and transmits force to the frame.
