Abstract
A controllable gripper assembly utilizes spaced plates attached to transport chains. A gripper carriage is carried between the plates and is slidable with respect to the transport chain. Movement of the gripper carriage in a direction opposite to that of the transport chains will allow the sheet being transported by the gripper carriage to be released for deposit on a sheet stack with essentially no forward velocity.
Claims6
A controllable gripper assembly for delivery of sheets in a printing press to a sheet stack, said controllable gripper assembly comprising:
- first and second spaced, generally parallel transport chains which follow a path around chain wheel drive and chain reversing wheels;
- a plurality of controllable gripper units secured to said first and second transport chains, each of said controllable gripper units having spaced first and second plates attached to said first and second transport chains;
- a gripper carriage secured between each said first and second plates and slidable on said plates in, and opposite to, the direction of movement of said first and second transport chains;
- releasable sheet gripping means on said gripper carriage;
- and
- means to slide said gripper carriage with respect to said first and second plates in a direction opposite to said direction of movement of said transport chains to reduce the speed of movement of said gripper carriage in said direction of said transport chains with respect to said transport chains.
