Abstract
Described is a method of making a non-porous composite cover material formed of a pile material and an adhesive layer made from polypropylene or predominantly from polypropylene. A width of the pile material is advanced, and a layer of adhesive is applied thereupon. The adhesive is allowed to set, and the width of material is longitudinally cut into strips of composite cover material. Laminated paint rollers are thereafter made by helically one or two strips of polypropylene or strips made predominantly of polypropylene about a mandrel and applying a layer of adhesive made from polypropylene or predominantly from polypropylene on the strip or strips, and applying a non-porous composite cover material. A compressive force is applied upon the outer surface of the composite cover material to urge the composite cover material, the layer of adhesive and strip or strips of thermoplastic material together against the mandrel, thereby laminating the inner surface of the composite cover material and the strip or strips together and forming a continuous product that can be cut and finished to make paint rollers.
