Patent number: 9815296Abstract: A method for controlling the temperature of a sheet in a printing machine includes measuring initial temperatures in zones on the sheet. Segments of an emitter are actuated in different ways as a function of the measured initial temperatures for irradiating cooler zones to a greater extent and warmer zones to a lesser extent or not at all. A common final temperature or at least a homogenization of the temperature is therefore achieved in the zones.Type: GrantFiled: September 29, 2016Date of Patent: November 14, 2017Assignee: Heidelberger Druckmaschinen AGInventors: Andreas Mueller, Alexander Knabe, Rolf Mueller, Kai Oskar Mueller, Peter Hachmann, Michael Gieser, Wolfgang Dolz, Thomas Schmidt
