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.

A dryer fabric for use in a dryer section having a closed transfer in a papermaking machine. The dryer fabric has a structure of woven threads with one side, called the paper side, being adapted to support and abut against a paper web in the dryer section. At least some of the threads contacting against the paper web are hydrophilic, thereby providing for adhesion between the dryer fabric and the paper web.

A transfer belt for eliminating an open draw between a press in a papermachine and a transfer point has a supporting base with a particle-filled polymer coating. The coating, which constitutes the paper side of the transfer belt, carries the paper sheet from a press nip in a closed draw to a transfer point without sheet flutter or drop-off. At the transfer point, the paper sheet is readily released to another sheet-conveying papermachine-clothing product. The transfer belt may carry the sheet through more than one press nip. The transfer belt surface has a pressure-responsive recoverable degree of roughness, which is made relatively smooth by compression in the press nip, allowing the thin, almost continuous water film to form between the transfer belt and the paper sheet. When leaving the press nip, the paper sheet is held to the transfer belt by the thin, almost continuous water film. Following exit from the press nip, the transfer belt surface recovers its uncompressed roughness, breaking up the water film, so that, by the time the paper sheet reaches the transfer point, it is readily released by the transfer belt to the next sheet-conveying papermachine-clothing product, which might be a felt, a belt, or a fabric.
