Abstract: A method of cut position determination for printing machines, wherein in order to ensure a synchronous running of the paper webs (P1-P4) to be folded and cut into newspapers (16) on a printing machine for rotary offset printing or rotary letter press printing, main and secondary registers (5, 7) are controlled in their position by means of servomotors (M1-M4) as a function of actuating signals (S.sub.M1 -S.sub.M4). Above each former-introduction guide roller (10), 4 photocells (11) are arranged equally spaced next to one another, which detect brightness signals (H.sub.A1 -H.sub.D4) from the printed surface of these paper webs at a scanning frequency of 20 khz. These brightness signals are subjected to a Fourier analysis in a microprocessor. The fundamental oscillation is evaluated, the fundamental oscillation with the greatest amplitude being selected from the 4 fundamental oscillations of each paper web.
Abstract: Apparatus and procedure for accurately positioning and magnetically holding a flexible ferrous plate on the surface of a rotary printing cylinder. Movable registering pins and a permanent bar magnet are mounted to the rotary cylinder and controlled by a single operating means. The pins and magnetic bar are alternately moved toward and away from the cylinder surface such that, when the pins are initially projected to register with positioning holes in the plate, the magnet is withdrawn. When the pins are withdrawn the magnet is simultaneously advanced to "grab" the leading edge of the plate. The operating means is controlled by a foot pedal linkage. The trailing edge of the plate is held in position by a second bar magnet. To remove the plate, the procedure is reversed so as to simultaneously advance the register pins and retract the bar magnet to release the leading edge of the plate.
Abstract: An apparatus and method for oscillating the ink form rollers and dampening form roller in a lithographic printing press to apply a smooth, relatively uniform coating of ink to the ink-receptive areas of the lithographic printing plate and to prevent ink from being transferred from the dampening form roller to the ink-rejecting areas of the printing plate. The ink form rollers and the dampening form roller are each mounted on a shaft rotatable about its own axis. The shaft has at least one shaft key for mating with a complementary keyway in a bushing which is inserted at least partially into the central opening of the corresponding roller. The engagement between the shaft key and the bushing keyway allows the roller and bushing to engage the shaft for common rotation while permitting the roller and bushing to slide axially with resepct to the shaft.

Abstract: A printing web tensioning system that is activated in response to a break in the printing web. The system includes a pair of tensioning rollers which bracket the paper web and are movable between a spaced disengaged position and a contacting engaged position. The pair of tensioning rollers are driven by a variable speed motor, the speed of which is synchornized with the speed of the printing cylinders. Hydraulic rams are attached to the tensioning rollers to move them from the disengaged position to the engaged position when a break in the printing web is detected and the printing unit begins to shut down. Since the speed of the tensioning rollers is synchronized with the speed of the printing cylinders, web tension is maintained and a small quantity of paper web is advanced forward and collects on the floor during the shut down process. By maintaining tension on the printing web, paper is prevented from wrapping around the printing cylinders and causing damage to the print blankets.
