<p>The roller (1) has a roll cover (4) covering a generated surface of a cylindrical roller base (3), and comprising a top layer (7). The top layer lies outside, and is made from a material mixture (8) with a polymer material. A filler material (9) is sectionally embedded into the polymer material and formed from fluorine containing material e.g. polytetrafluoroethylene, polyvinylidene fluoride and fluorinated ethylene propylene. The filler material has a higher abrasion resistance and a smaller detention and sliding friction coefficient than the material mixing.</p> |
