2009
The invention relates to a device having a roll cover (12) for a calender roll (10) and a doctor blade (20) for Beschaben of the roll cover (12) at its working surface, wherein the radially outer circumferential surface of the roll cover (12) forms the useful surface, of at the working surface is formed adjacent the region of the roll cover (12) made of a material comprising a filler in the matrix (14) embedded first hard material grains (13), and the roughness of the working surface has a value within a predetermined tolerance range. The scraper blade (20) of the device comprises a fiber composite material which is ausgebildedt to Beschaben the effective area of the roll cover (12) and in the binder (27) and second hard material grains (31, 32, 33) are embedded, their hardness, particle size distribution and surface morphology is selected matched the tolerance range of the roughness of the working surface of the roll cover (12).
