Spiralkonstruktion eines gerillten Pressmantels für Breit-NIP-Presse |
摘要 |
A grooved, void-volume belt for use on a long nip press for dewatering a fibrous web may be manufactured by winding a grooved strip or ribbon of polymeric material onto a standard LNP belt in the form of a closed helix, and by attaching the grooved strip to the belt by suitable means. The strip may be extruded from a polymeric material, such as polyurethane, and is provided with at least one longitudinal groove. The method enables one to manufacture a grooved, void-volume belt without the prior necessity of coating both sides of a base fabric with a polymeric material, and of cutting grooves in the coating on the outer side of the belt. <IMAGE> |
