METHOD FOR MANUFACTURING RESIN-IMPREGNATED ENDLESS BELT AND A BELT FOR PAPERMAKING MACHINES AND SIMILAR INDUSTRIAL APPLICATIONS

摘要

A method for manufacturing resin-impregnated endless belt structures and beltfor apapermaking machine and for similar industrial applications are disclosed. Thestructures have improved or alternative mechanisms for extracting water from afibrous web. The method eliminates the necessity for a separate step(s) formanufacturing the similar endless belt having void volume in the form ofgroove,blind-drilled holes and the like on their outer surface. It requires theapplication of asacrificial material onto a base substrate in a predetermined pattern indroplets havinga diameter of 10µ(microns) or more. Polymeric resin material is depositedon the basesubstrate to cover all areas except those on which the sacrificial materialhas beenpreviously applied, and is set by means appropriate to its composition, andthesacrificial material removed. The polymeric resin material is abraded toprovide thebelt with a uniform thickness, and a smooth, macroscopically monoplanarsurface.
