Abstract
A reversing gripper apparatus of a one side/perfecting printing press is disclosed. This reversing gripper apparatus comprises a receiving portion wherein a gripper pad fixed to the external circumference of a reversing cylinder grips a sheet of paper in combination with gripper members and a space for withdrawal, the gripper members comprise a combination of a master gripper provided on a common shaft and an auxiliary gripper opposed to the master gripper, the master gripper is formed with a width sufficient to cover the receiving portion of the gripper pad and the point of the auxiliary gripper at the same time and is controlled by a common shaft, and the auxiliary gripper has such a width as to be partly opposed to the width of the master gripper and is controlled with the common shaft as the center. By adopting this structure, the gripping function, register accuracy, and the gripping force of the reversing gripper apparatus are greatly increased.
