Printing machine with one or more printing units in the form of printing towers for double-sided multi-colour printing and a device for tempering components of one or more of the printing units

摘要

The machine has two secondary circuits containing fluid of a primary circuit metered via a feeding station for controlling temperature of to be temperature-controlled components. Two different printing devices (04) have thermal interactions with the respective secondary circuits different from each other for controlling the temperatures of the components. A selectively actuatable electrical heating appliance is provided in addition to the feeding station. A set of valves, pumps, and the heating appliance are associated with the secondary circuits.
