    摘要： A screen-printing unit in a printing machine comprises a screen cylinder which carries a screen-printing stencil and in which a squeegee is moved, from the inside, into contact with, and away from the screen-printing stencil. The screen cylinder is moved into contact with an impression cylinder, such that a printing position is formed, and is moved away therefrom, such that a gap is formed. The screen cylinder is moved away from the impression cylinder, in a first phase, when the squeegee is in a non-contacting position. In a second phase, at least one sheet of printing material is passed through the printing position when the squeegee continues to be in a non-contacting position and the screen cylinder is at least temporarily in a contacting position. For subsequent sheets of printing material, in a third phase, the screen-printing unit is operated with the squeegee one of permanently and cyclically, such as at least once for each sheet of printing material, in a contacting position.

    摘要： A printing module of the flexo printing type, is provided with an anilox roller and an impression roller which are set up between two frame parts. Further, the printing module comprises a plate cylinder assembly which is receivable in a plate cylinder holder assembly. The plate cylinder holder assembly is provided with a plate-shaped body part with a supporting ring support surface with a special curve which is symmetrical with respect to a curve plane. Further, each plate cylinder holder assembly comprises a body part support assembly via which the body part is connected with the associated frame part, wherein the body part support assembly is configured for pivoting the body part about a first imaginary pivoting axis and for pivoting the body part about a second imaginary pivoting axis, such as to allow a substantially independent distance setting between the plate cylinder and the anilox roller on one side and between the plate cylinder and the impression roller on the other side.

    摘要： A method and apparatus for setting the positioning between a first rotating member and a second fixed or rotating member in a rotary machine comprises controlled thermal elements positioned on the frame supporting the members and/or on the rotating member(s) itself to counteract the effects of centrifugal force on the rotating member(s) to thereby approximately maintain the setting between the members. In one embodiment, the temperature of the frame controlled by the thermal elements may be maintained in proportion to the speed of rotation of the rotary member(s) to maintain the setting of the rotary machine throughout its operating speed range. In another embodiment, the initial setting between the first and second members may be precisely set by the controlled thermal elements at or near the setting representing the minimum useful loading, and due to the effect of centrifugal force be allowed to diminish to within the range of useful operating pressure or clearance. In another embodiment, a predetermined initial setting between the first and second members is substantially maintained by monitoring the effects of centrifugal growth on the apparatus and adjusting the temperature of the frame supporting the first and second members to push the members apart to compensate for centrifugal growth.

    摘要： A method and apparatus for setting the positioning between a first rotating member and a second fixed or rotating member in a rotary machine comprises controlled thermal elements positioned on the frame supporting the members and/or on the rotating member(s) itself to counteract the effects of centrifugal force on the rotating member(s) to thereby approximately maintain the setting between the members. The temperature of the frame controlled by the thermal elements can be maintained in proportion to the speed of rotation of the rotary member(s) to maintain the setting of the rotary machine throughout its operating speed range. A predefined temperature may be set by the thermal elements prior to the manual setting of the rotary machine so that the temperature of the frame and/or rotating member(s) can be controlled to compensate for wear of the rotating member(s) in machines wherein such member(s) encounters wear over operating time.
