Granted: 2002-02-01
Abstract: A resin-coated endless belt for a long nip press has a base which is a polymeric film structure in the form of an endless loop with an inner surface, an outer surface, a transverse direction and a longitudinal direction. The polymeric film structure has a plurality of perforations which may be aligned in one or both of these directions. The polymeric film structure is stretched in the presence of heat to orient the molecular chains in the unperforated intervals between the perforations to provide the structure with tenacity and resistance to further stretching. At least the inner surface of the base (polymeric film structure) is coated with a polymeric resin material, such as polyurethane. The polymeric resin material coats the base and upon curing, forms a mechanical interlock therewith by virtue of the perforations, and renders it impermeable to oil and water. In addition to being useful for a long nip press, the belt may also be used in other papermaking applications, for example, as a calender belt on a calender of the shoe type or on a calender having two or more rolls, or as a transfer belt.
