ABSTRACT:
An integral sheet stopping, stacking and lateral registration system, in which sequential incoming sheets are fed into a tray and stopped at an edge registration position and also repositioned laterally by lateral sheet repositioning scuffers engaging an edge of the sheets at the edge registration position, with improved protection against sheet edge distortion or damage provided by movable partial sheet stopping surfaces partially shielding the incoming sheet lead edge from full impact with the lateral scuffers but without interfering with the subsequent lateral movement of the sheets by the lateral scuffers. The incoming sheets are fed in and stacked under a stack-floating curved input guide baffle and floating frictional input flapper scuffers feeding and holding an incoming sheet downstream against the lateral scuffers for improved lateral registration. The movable partial sheet stopping surfaces are mounted to ride vertically on the floating baffle and also ride horizontally against the lateral scuffers and thereby maintain a desired preset spacing relative thereto.
