Abstract

In order to accurately align heavy paper in a printer or copier with a skewed belt aligner, large steel balls are used. This excess mass on the lighter paper drives it into the aligner reference edge with such an impact, it causes the paper to buckle, creating unacceptable alignment (Fig. 2). To eliminate this problem, a slot in the ball retainer mounting bracket allows the balls to rebound from the beam strength of the paper. By slotting the ball's retainers perpendicular to the reference edge, the skewed drive belt will keep the balls next to the aligner (Fig. 1).

Rebounding Ball on Belt Aligner

In order to accurately align heavy paper in a printer or copier with a skewed belt aligner, large steel balls are used. This excess mass on the lighter paper drives it into the aligner reference edge with such an impact, it causes the paper to buckle, creating unacceptable alignment (Fig. 2). To eliminate this problem, a slot in the ball retainer mounting bracket allows the balls to rebound from the beam strength of the paper. By slotting the ball's retainers perpendicular to the reference edge, the skewed drive belt will keep the balls next to the aligner (Fig.
1). Once the buckled paper is traveling along the aligner edge with the balls on top of it, there is no longer a force on the balls to keep them next to the reference edge, allowing the beam strength of the paper to move them away from the reference edge, allowing the paper to be perfectly aligned.
