Coater belt and a coating station including such a coater belt

摘要

A coater belt for carrying and supporting a web through a coating station on a paper or board machine, or an off-line coater, said belt comprising an endless base member and at least a first surface layer. Said surface layer is an impermeable coating comprising a first material and a particulate filler material. The filler material which are present in the web-contact surface provide a well-defined roughness on micro-scale of said web-contact surface. The web-contact surface further presents a well-defined surface energy for accomplishing an adhesion to the web for picking-up the web at an entrance side of the coating station and for holding the web against the coater belt during its path through the coating station.
