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.

Abstract: Paper web decurling apparatus comprising a freely rotatable relatively large diameter support roll and a freely rotatable small diameter decurling roller disposed parallel to the support roll for pressure engagement with a paper web thereon. Selectively operable means are provided for adjustably varying the pressure of the decurling roller against the paper web and support roll and selectively operable means are provided to rotationally position the decurling roller to engage the paper web on the support roll at any desired location circumferentially of said support roll.
