Abstract: A sheet reversing assembly for a rotary printing press utilizes one or more arcuately and radially movable gripper assemblies on an impression cylinder to elevate a gripped leading edge of a sheet to be reversed. As the trailing edge of the sheet is engaged by suction grippers on a reversing drum, air blast jets in the vicinity of the abutment surface of the gripper assembly direct air under pressure between the sheet and the surface of the impression cylinder.

Abstract: An adjustable sheet guide assembly utilizes a plurality of individually shiftable sheet guide elements. Each of these sheet guide elements is carried by a sleeve which is concentric about a hollow profile body that carries a rotatable, helically fluted shaft. Guide pins on the sleeves are received in the shaft's flutes so that rotation of the shaft or movement of one sheet guide element causes movement of all of the sheet guide elements in the adjustable sheet guide assembly.

Abstract: An offset inking unit for a rotary printing machine is disclosed. A single supply of ink, carried from an ink fountain through a distribution train that includes serially placed synthetic material coated ink receiving rollers and rubber coated ink intermediate rollers, is split by a distributing roller onto first and second ink forme rollers. The second ink forme roller has three subsequent ink forme rollers linked to it in a serial manner through rider rollers. Ink tack or stickiness is controlled to avoid ghosting by applying dampening fluid to either the first or last of the ink forme rollers or to both, if desired.
