<p>Described is a method of making a laminated paint roller wherein a perforated strip of thermoplastic material is advanced, the perforated strip having holes there-through. A lubricant is applied to the inner surface of the advancing perforated strip of thermoplastic material. The lubricated, perforated strip (23) of thermoplastic material is helically wound around a cooled mandrel (21) so as to form a helically wound strip (23) wherein the inner surface of the perforated strip faces the cooled mandrel (21) and the outer surface of the perforated strip faces away from the cooled mandrel. The wound perforated strip is advanced along the cooled mandrel. A layer of adhesive (25) is applied onto an outer surface of the wound perforated strip. A strip of composite cover material (17) is helically wrapped about the wound strip and over the layer of adhesive, the outer surface of the composite cover (17) material comprising a pile fabric (2), and the inner surface of the composite cover material comprising thermoplastic. A compressive force (28,28a,28b) is applied upon the composite cover material to urge the composite cover material, the layer of adhesive and strip of thermoplastic material together against the cooled mandrel, thereby laminating the inner surface of the composite cover material to the outer surface of the strip. A method of making a composite cover material is also disclosed.</p> |
