A method and apparatus for making reusable paint rollers comprised of a core formed from a strip of thermoplastic material. The thermoplastic material is formed into a core by helically winding about a stationary mandril. 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 thermoplastic strips about the mandril. In a second embodiment the core is formed by applying liquefied thermoplastic material to a driven belt which transfers the thermoplastic material to the mandril. 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 mandril.
