PAINT ROLLER AND METHOD AND APPARATUS OF MANUFACTURING A PAINT ROLLER

摘要

A paint roller with a thermal plastic core and a method and apparatus for making such a paint roller in a continuous, low cost production method in which a tubular plastic core is formed by laying up a two-ply wrap over a mandril with surface heating only of tha contacting ply surfaces to form a continuous, endless, unitary thermal plastic core structure, cooling the inside and outside surface of the core structure to a final internal diameter dimension and, following contracting of the internal core structure to a final desired diameter, heat bonding a compatible thermal plastic pile fabric to thg external surface of the core structure followed by separation of the continuously produced composite structure into final pieces.
