Abstract
The invention relates to a method for producing a paint roller having a roller body comprised of a synthetic foam with an inner recess for placement on a support arm. The invention is characterized in that the roller body is expanded in a molding tool. Towards this end, the expansion pressure is set such that a closed compact covering of the synthetic material, preferably a polyester polyurethane foam, is formed on the outer surface of the roller body and/or on the wall of the inner recess. The coating is at least partially opened or removed in a successive method step.
