    摘要: An apparatus for stretching a cylinder blanket on a sheet transfer cylinder of a sheet-fed printing press includes a tiltable member mounted on the cylinder. A first end of the blanket is first attached to the cylinder in a cylinder groove, the blanket is wrapped around the cylinder, and the second end of the blanket is attached to the tiltable member, while the tiltable member is in an open position. The tiltable member is then closed to stretch the blanket about the cylinder, and locked into the closed position to maintain the blanket about the cylinder.

    摘要: A sheet sensor arrangement for a sheet printing machine and particularly for a turning device of a sheet printing machine, which comprises at least one hollow cylindrical drum (3; 4), which has a gripper system to transport and/or temporarily store individual sheets (5). A sensor arrangement which is not very susceptible to contamination and has a mechanically simple structure is comprised of the fact that the cylindrical wall of the drum (3; 4) has at least one opening which allows light to pass through, and that a sheet sensor is formed by a light barrier (9, 10, 11), which has a light beam which, in at least one angle position of the drum, is directed from the inside at the opening which allows light to pass through. In addition, a corresponding process for optical monitoring of sheets in a sheet printing machine is indicated.

    摘要: A gripper device of a sheet-guiding system grips a leading edge of a sheet freshly printed on at least one side thereof. The sheet is guided along an imaginary guide path in a sheet travel direction extending perpendicularly to the leading edge of the sheet. A plurality of first air blast nozzles having respective nozzle openings emit an air flow onto a surface of the sheet. The air flow has a first main flow direction extending in parallel with and in the direction of sheet travel. A plurality of second blast nozzles emit respective air jet bundles in a respective second main flow direction perpendicular to the leading edge of the respective sheet. The first and the second main flow directions, respectively, intersect at a common starting point and define an angle therebetween having a maximum value of 90.degree. and, in a condition wherein the second main flow direction of the air jet bundles is inclined with respect to the guide path, an imaginary elongation of a central air jet of the air jet bundles, respectively, passing through the guide path and impacting with the first nozzle openings.
