Abstract

A dryer unit which is integrated as a module into a printed material guide system of a printing machine in order to facilitate two-sided drying of printed material is provided. The printed material guide system includes a guide surface which has a plurality of openings and an air system which is selectively operable in positive or negative pressure modes to assist the guiding of the printed material. The dryer module is arranged in an opening in the guide surface such that it heats at least one side of the printed material. At least one outlet opening is associated with the dryer module. The outlet opening is open into the plane of the guide surface and is coupled to a cooling system which is operable to provide cooling air to the dryer module.
