Abstract

A woven belt paper polisher imparts mechanical energy to paper by sliding a woven belt against a paper sheet while the sheet is supported against a shear inducing roll. The contact force, slide distance and the coefficient of friction of the polishing belt result in less polishing material wear, less chance for developing machine direction character on the paper surface, and less chance for machine component damage. The use of an extended belt run outside the polishing section, results in reduced wear, extended uptime, and better polishing surface reconditioning. The use of a commercially produced and modified woven paper machine fabric results in lower operating cost compared to the use of a specialty polishing material.
