A cam-free drive for a rocking lead edge gripper

Structure of mechanism
Function	The motion device described in the patent relates to a cam-free drive for a rocking lead edge gripper for handling sheets in a sheet fed rotary printing press. The edge gripper is based on a linkage with 7 links and 9 joints, which is driven by a gear train. The degree of freedom of the mechanism is F = 1.
