ABSTRACT:
A sheet turn-over assembly includes at least one cooperating pair of first and second sheet gripper sets. Each set has coacting sheet gripper fingers and sheet gripper abutment surfaces. These fingers and abutment surfaces in each set are carried on coaxially aligned rotatable shafts. Movement of one shaft with respect to the other accomplishes sheet gripping and release. Movement of the coaxial shafts of each gripper set with respect to the cooperating set accomplishes sheet turn-over.
