  • Method for improving the cleanability of coated belts with a needled web on the inside surface
    Patent number: 6036819
    Abstract: A polymeric-resin-coated papermaking-processing belt, which may be used as a sheet-transfer, long nip press (LNP) or calender belt, includes a reinforcing base having the form of an endless loop with a face side and a back side, these being the outside and inside of the endless loop, respectively. The face side of the reinforcing base is coated with a polymeric resin material, while the back side has a staple fiber batt attached thereto. The staple fiber batt has a smooth, fused surface free of protruding fiber ends. This surface is kept clean more easily than that of a typical staple fiber batt. Methods for manufacturing the polymeric-resin-coated papermaking-processing belt, including several ways for providing the staple fiber batt with the smooth, fused surface, are also disclosed.
