#CMT# #/CMT# The roller has a roller body and a cover layer made of polymer, particularly polyurethane, which is arranged on the roller body. The cover layer comprises a surface facing the fibrous material web, and has surface designs formed as grooves, suction holes or blind holes in the surface. The surface of the cover layer is provided with a water-repellent and stain-resistant coating. The coating completely or partially comprises a mixture of polyurethane or epoxy resin with an additive made of silicon nanoparticles, Teflon(RTM: Polytetrafluoroethylene), fluorine or silicon. #CMT# : #/CMT# An independent claim is included for a method for manufacturing a roller. #CMT#USE : #/CMT# Roller, particularly for a press section of a machine, such as a paper, cardboard box or tissue machine for producing or finishing a fibrous material web. #CMT#ADVANTAGE : #/CMT# The cover layer comprises a surface facing the fibrous material web, and has surface designs formed as grooves, suction holes or blind holes in the surface, where the surface and surface designs of the cover layer are provided with a water-repellent and stain-resistant coating, and thus enables a simple and economical structure of the roller, and an easy application of the coating during the rolling operation of the roller, and prevents contamination or staining of the fibrous material web by preventing adherence of water or dirt on the cover layer surface, and also improves the drainage efficiency of the roller. |
