ABSTRACT:
A method of making a coated abrasive article, and the product thereof, involving the steps of: providing a backing sheet having two free sheet ends and joining the two free sheet ends together as a splice to form an endless backing sheet; temporarily supporting the backing sheet before or after performing the splicing; applying fibrous reinforcing material onto a major surface of the endless backing sheet such as by winding at least one continuous fibrous strand or narrow fibrous strip in a plurality of revolutions around the endless backing sheet with applying of a first binder precursor to the fibrous reinforcing material such that the first binder precursor bonds the fibrous reinforcing material to the second major surface of the endless backing to form a reinforcing fiber layer; exposing the first binder precursor to conditions effective to solidify the first binder precursor; and forming an abrasive coating on the surface of one of the fiber reinforcing layer, or alternatively, the exposed surface of the backing sheet before or after applying the reinforcing fiber to the opposite side of the belt.
