Abstract

The invention relates to a device for treating a material web, preferably for dewatering a paper web (2) in the impulse drying process, having a heating roll (3) and a counter-support (4), which forms a press nip (5) together with the heating roll (3), at least the heating roll (3) consisting of a stationary axle, a roll cover (7) and at least one supporting element for supporting the roll cover (7) on the axle and the roll cover (7) has a base layer (9) and a thin ceramic operating layer (10) applied onto the base layer (9), the operating layer (10) having an improved energy efficiency and at the same time an improved mechanical stability. It is proposed that the ceramic operating layer (10) has a thickness of less than 1 mm, that the base layer (9) consists of a ceramic material as a thermal insulation and that the base layer (9) has a thickness which is larger than the thickness of the ceramic operating layer (10). <IMAGE>
