A paint roller is obtained by continuously forming a tubular plastic core, preferably by laying up a two ply wrap over a mandrel (11) with surface heating only of the contacting ply surfaces to form a continuous, endless, unitary thermoplastic core structure, cooling the inside and outside surface of the core structure to a final or near final internal diameter dimension, and, following contracting of the internal core structure to a final desired diameter, heat bonding a compatible thermoplastic pile fabric to the external surface of the core structure, followed by separation of the continuously produced composite structure into final pieces suitable, if desired, for use or further processing. <IMAGE> |
