发明名称 SPIRAL CONSTRUCTION FOR A LONG NIP PRESS BELT
摘要 A belt (16) for use on a long nip press (10) for dewatering a fibrous web (17) may be manufactured by winding an elongated strip (36) onto a pair of process rolls (32,34) to form a closed helix. Adjacent coils of the closed helix are bound to one another with an adhesive. The elongated strip includes a reinforcing web (50) coated on one side (56) with a uniformly smooth coating of a polymeric resin. The other side (58) of the reinforcing web is coated with another polymeric resin of higher hardness value, and is provided with grooves (66). The elongated strip is wound onto the process rolls to produce a belt with a grooved outer surface. The method facilitates the manufacture of belts of a variety of widths and lengths. <IMAGE>
