ABSTRACT:
A paper conveying apparatus for a sheet-fed press includes a shaft, a gripper shaft, a plurality of grippers, a gripper pad, levers, a rod, a slide member, rollers, and cam plates. The shaft has two ends pivotally supported by a pair of frames. The gripper shaft extends parallel to the shaft and swings upon pivotal movement of the shaft. The plurality of grippers are aligned on the gripper shaft. The gripper pad extends to be parallel to the gripper shaft and swings upon pivotal movement of the shaft. The grippers and the gripper pad grip the end portion of a sheet conveyed from upstream a paper conveying direction by cooperation thereof, and convey the sheet to a cylinder downstream the paper conveying direction. The levers, the rod, the slide member, the rollers, and the cam plates reciprocally move in the axial direction of the shaft to flex the central portions of the gripper pad and gripper shaft in the paper conveying direction.
