Title:
GROOVED LONG NIP SHOE PRESS BELT
Document Type and Number:
WIPO Patent Application WO2002036879
Kind Code:
A3
Abstract:
A resin-impregnated endless belt (16) for a long nip press (10) of the shoe type has a base structure (28) impregnated by a polymeric resin (34) material which renders the belt impermeable to fluids, such as oil, water and air. The polymeric resin material (34) forms layers (22, 24) on the inner and outer sides of the base structure (28). The inner layer (22) is smooth, but the outer layer (24) has primary grooves (26) for the temporary storage of water pressed from a paper web. The primary grooves (26) are separated by land areas (36) which have secondary grooves (38) extending thereacross to relieve stresses which give rise to flex fatigue and stress cracking.
