Abstract: In a device according to the invention for the automatic charging of processing stations (1) with printing cylinders (9) a number of charging stations (2) is provided, each being designed as input location for entering the printing cylinder (9) into the device, as storing location for storing the printing cylinder (9) before and after processing, and as output location for delivering the printing cylinder (9) from the device after processing. The printing cylinders (9) may each be supplied to the processing station (1) by means of a crane (3) without being required that the operator must wait at the device until the crane has terminated its operation.

Abstract: The invention is directed to a clamping device for gravure printing cylinders to be processed in an electroplating plant. The clamping device for gravure printing cylinders to be processed in an electroplating plant is equipped, in accordance with a first basic solution, with an interchange holder (1) for a plurality of cone sleeves (2) which have an inside diameter adapted to different spindle ends of various gravure printing cylinders, so that adaptation to a respective identical receiving cone quill (8) is made possible and in the same electroplating plant a plurality of different printing cylinders can be continuously successively processed without the complicated fitting and removal of different collet chucks. According to a second basic solution the interchange holder and the different cone sleeves are not required for the clamping device. Instead, a hardened cone sleeve (21) is used as essential clamping element and clamping is effected with very high contact pressure.

Abstract: An electrophotographic copying apparatus wherein the original is placed face down onto a stationary transparent holder which is located above a reciprocating carriage for a lens element. The latter images the original onto a light receiving surface which travels along a straight path while the carriage moves in the same direction as the light receiving surface. The carriage can be moved by an eccentric drive, by a wiper which is attached to an endless belt or chain, or by a cam and follower assembly. The original is illuminated by flash lamps which are fired automatically while the carriage moves in the same direction as the light receiving surface.

Abstract: A copying machine wherein successive finished sheets issue from an opening in the front wall of the housing in such positions that the printed matter is observable from above. Successive sheets pass below an observation window which is adjacent to the opening so that the quality of printed matter can be observed from above. The sheets are thereupon inverted so that the printed matter faces downwardly, and are stacked on top of each other in a tray having a bottom panel the inner end portion of which constitutes the observation window. The sheets are inverted in a channel having an inlet below the observation window and an outlet above the end of the tray which is remote from the opening.
