Abstract
A method and apparatus for making reusable paint rollers comprised of a core formed from thermoplastic material. The thermoplastic material is formed into a core about a stationary mandril. An adhesive is then applied to 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.
