ABSTRACT:
A rotary printing machine has a plate cylinder and a liquid supply apparatus comprising an inker and a damper. The liquid supply apparatus includes rollers and an endless band guided over two deflection rollers. The band, which has a surface that accepts ink and damping fluid and extends over the width of the rollers, is provided with guide elements cooperating with counterpart guide elements attached to the machine. The guide elements and counterpart guide elements are embodied such that the band is displaceable at right angles to the axes of two rollers and is additionally pivotable at least about one of the axes of a deflection roller. Positioning means supported firmly on the machine are also provided for fixing the band in at least two different operating positions, in which the band is in contact with one or two rollers of the liquid supply apparatus. As a result of the different screw-down positions of the band that thus become possible, various kinds of disruptions in the supply of liquid to the plate cylinder can be counteracted.
