The reusable paint roller (50) produced in accordance with the invention is comprised of a core formed from a strip of thermoplastic material (24, 26, 28). The thermoplastic material is formed into a core by helically winding it about a stationary mandrel (14). A layer of adhesive is then applied to the outer surface of the core whereupon a cover is bonded thereto. In a first embodiment, the core is formed by winding a plurality of the thermoplastic strips (24, 26, 28) about the mandrel. In a second embodiment the core is formed by applying liquefied thermoplastic material to a driven belt which transfers the thermoplastic material to the mandrel. In yet another embodiment, the paint roller is made by bonding, in a single step, a fabric cover strip to a wound strip wrapped about the mandrel. <IMAGE> |
