An access door and interlock guarantees that the cylinders are turned to a normal position and braked before the access door is opened, and the access door cannot be closed for subsequent printing until changeover has been completed. An indicator array indicates the sequence of adjustments to follow and abnormal conditions.

Abstract: In a rotary printing machine, an arrangement for mounting an applicator roller and a preceding roller in a fluid feed stream journals the applicator roller and the preceding roller to the printing machine frame with substantial bearing play, and spring loads the applicator roller against the bearing surface away from the plate cylinder.On passing through the cylinder gap the applicator rollers of inking, damping or varnishing units in sheet-fed offset presses are jolted both at the start and end of the gap. The resulting different flattening of the soft applicator rollers causes roller marks, which should be avoided. For this purpose the applicator roller and the preceding roller are braced against each other by springs, so that their bearing play is eliminated and the distance between shafts is constant. This condition is also maintained on passage through the gap. Conveyance of liquid between applicator rollers and the preceding rollers is thus constant.

Abstract: A delivery mechanism for a sheet fed printing press in which a rear edge guide in the form of a traverse member guides the rear edges of the downwardly settling sheets into a condition of register. A brake assembly is provided for engaging the trailing edges of the sheets to decelerate them, the assembly being horizontally adjustable to accommodate sheets of different length and the traverse member being coupled by linkage to the brake assembly for simultaneous adjustment therewith. An intermediate stacking mechanism is provided having a horizontal frame and an intermediate pile receiver which is shiftable between a receiving position and an out-of-the-way position for temporarily accumulating sheets during a pile change. Detent assemblies at the ends of the traverse member lock the traverse member to the frame following horizontal adjustment.

Abstract: A device for application of lacquer or the like to a sheet in a printing press. The lacquer is applied by an applicator cylinder having an associated applicator roller. Lacquer is fed from a fountain having a fountain roller which is slowly driven, the lacquer being transferred from the fountain roller to the applicator roller either directly or through intermediate rollers to form a nip in which the lacquer tends to build up. The amount of lacquer transferred by the fountain roller per unit time is determined by a metering roller which engages the fountain roller. A sensing device located at the nip senses the level of lacquer buildup and produces an output signal upon departure of the building from an optimum level. In one embodiment of the invention the output signal is utilized to bring about a corrective adjustment in the position of the metering roller so that the buildup at the nip tends to be restored to optimum level.

Abstract: An inking unit for a printing press including a source of ink, a set of ink transfer rollers for establishing an ink film, a distributor roller vibrated endwise for distribution of the ink film and a form roller for applying the ink film to a plate on the plate cylinder. The form roller has a shaft and an outer cylindrical shell, the latter being rotated by surface engagement. A bearing between the shaft and the shell permits relative axial as well as rotational movement. A cam of the cylindrical, or drum, type mounted on the shaft has an endless wavy groove in which is received a cam follower in the form of a roller extending radially inwardly from the sleeve so that the sleeve reciprocates through a single cycle as a result of a single relative rotation of the shaft.

Abstract: A feed assembly for feeding sheets seriatim from a position of register on a feed table to an impression cylinder in a printing press which includes a pre-gripper having an oscillating connection with the press drive for periodically swinging the pre-gripper from a sheet pick-up position at the front edge of the table to a sheet-releasing position at the surface of the impression cylinder. The pre-gripper has a jaw and a jaw lever for opening and closing the jaw. A gripper operating cam is arranged in the path of movement of the jaw lever as the pre-gripper oscillates back and forth, the oeprating cam being mounted for retreating and return movement to control the opening and closing movement of the jaw. A rotating control cam coupled to the press drive has a control cam follower with a linkage for connecting the same to the gripper operating cam for controlling its retreating and return movement so that the jaw is closed upon an awaiting sheet at the pick-up position.

Abstract: A sheet-fed rotary printing press having lower and upper blanket cylinders in running engagement with an impression cylinder to form nips accessible through an access space. The driving means for the cylinders includes an inching circuit and a drive enabling circuit. An interlock switch adjacent the access space is connected in the drive enabling circuit. A safety subassembly and a washing subassembly are provided with quickly disengageable means for mounting the subassemblies in position successively in the access space. The safety subassembly includes a guard plate having a normal position in which the plate closes off the access space and forms a sheet guide. A first disengageable linkage couples the guard plate to the interlock switch so that when the plate is in its normal position the enabling circuit is enabled for normal driving of the press and so that when the guard plate is absent from its normal position the press is limited to inching movement.

Abstract: A device for registering of sheets, received in an underlapped stream, upon a feed table. The feed table has a retractable front stop and a side guide defining a condition of accurate register for the sheet. Cooperating with the side guide is a wiping mechanism which includes a lower wiping member and a cooperating upper wiping member for engaging a sheet between them for wiping the same into laterally registered position. A pre-gripper grips the leading edge of a registered leading sheet for transporting it forwardly and upwardly to a receiving cylinder thereby forming a wedged-shaped gap above the following sheet. Upon formation of the gap the upper wiping member is momentarily inserted into the gap in active wiping position, with the result that the following sheet is fully registered while it is still partially covered by the leading sheet.

Abstract: A dampening system for a lithographic printing press which includes, in series, a driven fountain roller, an adjustable intermediate roller, a driven distributor roller, and an adjustable form roller, the latter engaging the printing plate, the intermediate and form rollers being mounted upon respective throw-off levers. A single actuator is used, connected to the form roller throw-off lever. The intermediate roller throw-off lever is effectively in the path of final movement of the form roller throw-off lever, for throw-off by the latter, so that upon subsequent restoration to working position a water path is completed progressively through all of the rollers starting with the fountain roller, and with the form roller touching the plate last, thereby to insure, regardless of the length of the period of throw-off, that the form roller will be wetted to proper degree, free of either flooding or starvation, before being applied to the plate.
