    Abstract: A coater assembly includes a feed pump and a return pump for circulating a liquid coating material through a doctor reservoir for applying protective or decorative coating material to freshly printed sheets in an offset rotary printing press. A portable console control unit includes circulation and wash-up components for operating the coater in a PURGE/replenishment mode, a COAT mode, a WASH mode and a DRAIN mode. The components for pumping and valving the coating liquid and cleaning liquid are integrated within the portable console unit, which may be remotely located with respect to the press. Cleaning liquid and waste materials are stored internally within the portable console unit. The various operating modes are coordinated by two position, three-port flow control valves which are actuated from one position to the other by electrical solenoids under the control of ON-OFF switches. The ON--OFF switches may be actuated manually, or automatically by a cyclic controller for providing PURGE, COAT, WASH and DRAIN modes. The system may be cleaned without removing the coater or coater parts from the press, and without exposing press personnel to potentially toxic waste materials. The coater assembly may be operated in combination with the plate, blanket or delivery/transfer cylinder.

    Abstract: A system for curing printing plates with controlled radiant energy sources. A conveyor moves a printing plate through a chamber having energy radiators above and below the conveyor. Power to the radiators is controlled for each radiator or to groups of radiators defining radiation zones. Curing time may be controlled by adjusting power to the radiators and adjusting the conveyor speed. Sensors detect a plate as it enters and exits the chamber. Heat sensors may detect chamber or plate temperatures. A color sensor may detect plate color as an indicator of degree of curing. A computer system stores curing scenarios and uses the sensor signals and operator inputs to control power to the radiators and conveyor speed to provide uniform curing of the plate.

    Abstract: A transfer or delivery cylinder for a sheet-fed rotary printing press having an endless chain conveyor carrying gripper bars and grippers and driven by a sprocket wheel concentrically mounted on a drive shaft for pulling freshly printed sheets from the impression cylinder onto the transfer or delivery cylinder for movement to a further processing station within the press, wherein the transfer or delivery cylinder is a right circular cylinder eccentrically mounted to the drive shaft so that upon initial engagement of the freshly printed sheet by the grippers, the leading edge of the cylinder is spaced below the sheet which is thereafter pulled smoothly and uniformly into contact tangentially with the sheet support surface of the transfer or delivery cylinder.
