ABSTRACT:
A sheets aligner is provided with a frame body having vertical surfaces perpendicular to each other, a vertically movable table supported within the frame body, and a plurality of front lays extending along the respective vertical surfaces, thereby to stack on a pallet sheets fed to a sheet feed device for a sheet-fed printing press while aligning the sheet edges by vibration. The sheet aligner is provided with an opening formed in one of the vertical surfaces which is positioned in a direction to the sheet feed direction, the opening being adapted for permitting the pallet to be protruded from the frame body, a pallet stopper for stopping the pallet extruding from inside toward outside of the frame body, and a stop for closing a gap between each lower end of the front lays and the upper surface of the pallet. Thus, this arrangement permits a pallet e.g. for a maximum sized sheet to be used commonly to various sheet sizes. In addition, the provision of the auxiliary stop can eliminate the possibility that sheets are protruded toward the outside of the frame body even under condition vibration is present.
