  • Patent number: 4311093
    Abstract: A feed assembly for feeding sheets seriatim from a position of register on a feed table to an impression cylinder in a printing press which includes a pre-gripper having an oscillating connection with the press drive for periodically swinging the pre-gripper from a sheet pick-up position at the front edge of the table to a sheet-releasing position at the surface of the impression cylinder. The pre-gripper has a jaw and a jaw lever for opening and closing the jaw. A gripper operating cam is arranged in the path of movement of the jaw lever as the pre-gripper oscillates back and forth, the oeprating cam being mounted for retreating and return movement to control the opening and closing movement of the jaw. A rotating control cam coupled to the press drive has a control cam follower with a linkage for connecting the same to the gripper operating cam for controlling its retreating and return movement so that the jaw is closed upon an awaiting sheet at the pick-up position.
