摘要

A printing press sheet conveyor having a pair of endless chains mounted for movement around drive sprockets and a plurality of gripper carriages carried between said chains for receiving and transporting sheets between one transfer station adjacent a pair of said sprockets to a remote transfer station. The gripper carriages each include a shaft with a plurality of gripping pads and a corresponding number of grippers mounted for coaction with the pads. The gripper pads of each carriage are of progressively decreasing height from the ends of the shaft to the center thereof so that when the shaft is conveyed around chain support sprockets at a transfer station and deflects slightly outwardly due to the resulting centrifugal forces exerted on the shaft the bearing pads rise to a substantially common level for uniformly receiving a sheet at the transfer station. There is also disclosed an efficient method for producing a gripper carriage with gripper pads of such progressively different heights.
