Abstract: Rotatable transfer drum removes signatures by their folded edges one at a time from a hopper and presents them to a supporting plate with their open ends extending beyond one edge of the plate. The first of a pair of rotatable signature opener drums is arranged to take the open end of each signature lying on the plate in such a fashion that a fairly sharp bend is put in the open end, thus enabling easy signature opening when the outer side is released for taking by a vacuum gripper on a second opener drum. The first opener drum is provided with long gripper fingers, short gripper fingers, and one or more vacuum grippers, for handling different types of signatures having high and low folio laps or no lap at all. The gripper fingers are operated by stationary cams on one side of the first opener drum, and a vacuum line to the vacuum gripper is provided at the opposite side of the drum and is connected to the rotor of a timing valve. The cams are coaxial with the opener drum and are held fixed in position by means of a stationary bracket extending radially from a frame member to the cams. Tamper plates or paddles are provided to engage signatures on the plate to provide a temporary steadying support when the grippers initially take hold of the open ends of signatures.
