ABSTRACT:
Web decurling apparatus wherein a paper web is urged against a deformable roller by a decurling rod which extends parallel to the roller is provided with a series of improved bearing assemblies carried in spaced relation by a back-up beam which overlies the decurling rod to limit deflection thereof as decurling pressure is applied. Each bearing assembly is adjustable relative to the decurling rod and includes a mounting block fastened to the back-up beam, a pair of spindles each having an eccentric on one end journalled in the mounting block, and a roller bearing mounted on the eccentric end of each spindle. The other end of the spindle protrudes from the bearing block and is engageable by a tool to enable a technician to rotate the spindle about its axis and hence to rotate the bearing into proper engagement with the decurling rod. A set screw carried by the bearing block releasably engages the spindle for locking the bearing in a selected adjusted position.
