Printing medium drying device for ribbon-shaped printing substrate in printing machine, has protective band guided around elements in circulating manner and extended through gap between elements

摘要

The device (17) has a resonance type microwave applicator (21) with two applicator elements (27, 28) directed to each other, where the applicator elements form a gap (30) for feeding a ribbon-shaped printing substrate. A band (42) is guided around the applicator elements in a circulating manner and extends through the gap between the applicator elements. A drive is provided for circulating movement of the protective band. A cooling and drying unit (53) cools and dries the band. A cleaning unit (51) cleans the protective band. An independent claim is also included for a printing machine for printing a ribbon-shaped printing substrate with a printing unit.
