    摘要: A method of tempering a printing press with a circulating tempering medium includes regulating a temperature of the tempering medium. The temperature at a first measurement location is measured for purposes of control during production printing by the printing press. The temperature at a second measurement location is measured during a tempering phase of the printing press preceding production printing.

    摘要: A method of aligning sheets prior to transferring them to a sheet-processing machine includes feeding a respective sheet, by a first sheet edge thereof, against a stop; gripping the sheet by at least one sheet holder, and displacing the sheet holder at least approximately transversely to the stop in a direction towards a first control region; and onwardly moving the sheet holder, while the sheet is held thereby, over a given first distance, after a second sheet edge has reached the first control region; and a device for performing the method.

    摘要: A method of aligning flat copies in a sheet-processing machine includes the steps of determining the actual position of a sheetlike material in relation to a coordinate system; implementing a nominal position of a cylinder that accommodates the sheetlike material to be aligned on the jacket surface of the cylinder by correctively controlling non-contacting radial/axial magnetic bearings so as to compensate for position changes of the cylinder or components thereof from the nominal position; and maintaining the cylinder in the nominal position thereof until the aligned sheet material is transferred to transport units arranged farther downline; a device for performing the method; a printing unit having the device; and a multicolor rotary printing machine having the device.

    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 method of correcting a position of sheet material on conveying elements, the sheet material extending from a surface of a first sheet-conveying element to a surface of a second sheet-conveying element following downline from the first sheet-conveying element, as viewed in a conveying direction of the sheet material, which comprises detecting an actual position of a leading edge of the sheet material by at least one sensor element disposed on the first sheet-conveying element; by a control unit, making a comparison between a nominal and the actual position of the sheet material; and, if the actual position deviates from the nominal position of the sheet material, causing an actuator to fix the sheet material to the following second sheet-conveying element so as to perform a correction of the position deviation; a reversing or turning device in combination with the correction device; a printing unit having the correction device; and a multicolor printing machine in combination with the correction device.
