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 bel t structures designed for use on a long nip press on a papermaking machine and for other papermaking and paper processing applications, requires the application of a sacrificial material (64) onto a base substrate (12) in a predetermined pattern in droplets having an average diameter of 10~ (10 microns) or more. Polymeric resin material (68) is then deposited on the bas e substrate to cover all areas except those (72) on which the sacrificial material has been previously applied. The polymeric resin material is then s et by means appropriate to its composition, and the sacrificial material remove d. Optionally, the polymeric resin material may then be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.
