Abstract: An arrangement for longitudinally oscillating a doctor blade relative to the form cylinder in a printing press. The arrangement includes a double armed rocker having one arm coupled to the doctor blade and the other arm coupled to a hydraulic cylinder. The rocker is mounted on a central eccentric portion of a pivot shaft through a one way idler bearing and the pivot shaft is rotatably supported in a counteracting one way idler bearing. By oscillating the rocker, through sequential operation of the double acting cylinder, the pivot axis of the rocker is continuously displaced, causing the points of reversal of doctor blade movement to be continuously varied independently of the press operation, while maintaining a uniform stroke. In the illustrated embodiment, a pneumatic control is provided for controlling operation of the hydraulic cylinder, and thus the rocker arm and doctor blade movement.

Abstract: An impression cylinder for a rotogravure press having a recessed sheet stock gripper mechanism with a swivelling mechanism that swivels the grippers within the cylinder contour by revolving the grippers around a theoretical axis on the cylinder contour. The swivelling is rigidly and precisely constrained along an arcuate path by a plurality of arcuate guides disposed along the axial length of the cylinder. The opening and closing of the grippers and the swivelling of the grippers into the cylinder contour are caused to occur in sequence synchronized to the cylinder rotation by cam followers on gripper shaft pivot arms cooperating with cam followers journaled to the gripper shaft that are spring pressed onto cam surfaces fixed to the machine frame at the ends of the cylinder.

Abstract: A fluid supply system for a lithographic printing press in which a fountain roller journalled in the frame of the press and driven at a slow speed is partially submerged so that a film of fluid is formed on its surface. A distributor roller is journalled in the frame parallel to the fountain roller and spaced therefrom to form a gap. A ductor roller movable broadwise in the gap is supported by a pair of arms which are, in turn, rigidly supported by a shaft journalled in the frame. A driving arm having a thrust rod connected thereto is rigidly secured to the shaft. The driving arm is coupled to a cam follower which engages a rotary cam so that upon rotation of the cam the shaft oscillates to swing the ductor roller back and forth for successive engagement of the fountain roller and the distributor roller to convey fluid therebetween. Opposed way surfaces are provided at the ends of the arms oriented generally perpendicular to the plane of the arms. Mounting blocks carrying the ends of the ductor roller are slidable on the way surfaces. Paired springs are provided on opposite sides of each of the mounting blocks in working opposition to one another so as to define a normal position of the ductor roller with respect to the arms. Upon engagement of the ductor roller with either the distributor roller or fountain roller, any relative overtravel of the cam follower is yieldingly accommodated by the deformation of the springs. A set screw in each arm prestresses the springs and adjusts the normal position of the ductor roller.

Abstract: A sheet-fed printing press installation comprised of a first press unit for printing on one side of a sheet and which is coupled by a chain type conveyor to a second press unit in which there is a transfer drum having a normal set of grippers and an auxiliary set of grippers for (a) additional printing on the same side of the sheet or (b) printing on the opposite side of the sheet. The conveyor has an inlet sprocket for taking of the sheet from the impression cylinder in the first press unit and an outlet sprocket for delivering the sheet to the impression cylinder in the second press unit. First and second transfer drums are interposed in series between the outlet sprocket and the impression cylinder of the second press unit, the first transfer drum having the normal and auxiliary set of grippers. When the auxiliary set of grippers is activated, the sheet is gripped at the trailing edge thereby to reverse the sheet for printing on the second side of the sheet in the second press unit. The sprocket chain is driven at a speed which is less than the peripheral speed of the first transfer drum so that the auxiliary set of grippers may remove the sheet more promptly from the conveyor and sprocket drum to avoid smearing of the printed side of the sheet. A vacuum type sprocket drum preserves accurate register of the sheet for gripping purposes and stationary vacuum plenums are provided for removing the sheet from the influence of the drum just prior to transfer from the conveyor to the first transfer cylinder.

Abstract: Sheet coating means for a printing press including a back-up cylinder and form cylinder having an associated fountain, the fountain having a fountain roller rotating adjacent the form cylinder. Also rotating adjacent the form cylinder is a first form roller which is coupled to the fountain roller via a dosing roller. The fountain and its associated rollers are mounted upon a subframe having provision for (a) shifting the fountain roller into liquid transmitting contact with the form cylinder and (b) shifting the first form roller into liquid transmitting contact with the form cylinder thereby, selectively, to change the length of the liquid transference path from the fountain to a sheet carried by the back-up cylinder in accordance with the drying speed of the coating material. In a preferred embodiment the fountain assembly includes a second form roller rotating adjacent the back-up cylinder for transmitting coating material directly from the fountain roller to the sheet thereby bypassing the form cylinder, extending the capability to use with coating materials of a viscous nature. Also in a preferred embodiment the fountain roller is driven by means separate from the press drive thereby to control the rate of application.
