Abstract
A feeding mechanism for feeding a web of paper in a paper handling system includes a feeding nip assembly having a driven roller structured to be rotatably driven about a first axis, and an idler roller structured to rotate about a second axis substantially parallel to the first axis. In addition, the feeding nip assembly is structured to apply a force to the idler roller to push the idler roller toward the driven roller. The force is applied in a direction substantially perpendicular to the first axis and the second axis. The idler roller is also structured to pivot about a third axis substantially perpendicular to the first axis, the second axis, and the direction of the force.
