ABSTRACT:
A rotary multi-color printing machine comprises a frame and a plurality of printing units each of which prints in a different color on sheet material passing through the machine. The printing units are mounted one above another in the frame so that the sheet material can pass successively through the printing units. Each printing unit comprises a counter-pressure roll, a blanket roll, a plate roll and an inking roll, the axes of the rolls being parallel. The plate roll and the blanket roll of each printing unit are rotatably mounted in a support. The counter pressure roll of each printing unit is rotatably mounted in the frame on one side of the support, and the inking roll of each printing unit is rotatably mounted in the frame on the other side of the support. The support is slidable relative to the frame in a direction which is horizontal and axial relative to the rolls. In this way, the sub-assembly of the support and all the blanket roll and all the plate rolls can be removed from the machine to change the plates.
