PRINTING MACHINES HAVING ONE OR MORE PRINTING UNITS DESIGNED AS PRINTING TOWERS FOR DOUBLE-SIDED MULTICOLOR PRINTING AND DEVICES FOR CONTROLLING THE TEMPERATURE OF COMPONENTS OF ONE OR MORE OF THE PRINTING UNITS

摘要

The invention relates to a printing machine having one or more printing units (01) designed as printing towers for double-sided multicolor printing, and to a device for controlling the temperature of components of one or more of the printing units (01), wherein the printing unit (01) comprises a plurality of printing devices (04) disposed vertically one over the other, each having at least one component (07; 12) to be temperature-controlled, wherein the component (07; 12) to be temperature-controlled has a thermal interaction with fluid of a secondary circuit (14; 16) via an inlet (17), wherein the secondary circuit (14; 16) can have fluid of a primary circuit (19; 29, 35) metered via a feeding station (21) for controlling the temperature thereof, wherein components (07; 12) to be temperature-controlled of at least two different printing devices (04) have thermal interactions with two secondary circuits (14; 16) different from each other for controlling the temperatures thereof, wherein a selectively actuatable electrical heating appliance (26) is provided in the secondary circuit (14; 16) in addition to the feeding station (21), and that at least valves (24) and/or pumps (22) and/or heating appliances (26) associated with the two secondary circuits (14; 16) different from each other on a front machine side are disposed at different heights from each other, and/or can be fed with fluid from the primary circuit (19; 29, 35) by feeding stations (21) disposed at different heights.
