METHOD FOR MAKING A SPLICELESS COATED ABRASIVE BELT

摘要

A method of making a flexible coated abrasive belt comprising the steps of: mounting an endless, spliceless backing loop substrate having an exposed front surface and a back surface tautly on a peripheral surface of a temporary support structure; applying a continuous fibrous reinforcing material onto said front surface in a plurality of revolutions; applying a coating of a first binder precursor onto said front surface; exposing said coating to conditions effective to solidify said first binder precursor and bond said fibrous reinforcing material to said front surface to form an endless spliceless reinforced backing; and applying an abrasive coating comprising abrasive particles and adhesive over said back surface or said front surface of said endless spliceless reinforced backing.
