The invention relates to a method for producing a paint roller having a roll body comprised of a synthetic foam with an inner recess for placing on a carrying strap. The invention is characterized in that the roll body is expanded in a form tool. To 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 roll body and/or on the wall of the inner recess. The coating is at least partially opened or removed in a successive method step.
L'invention concerne un procédé permettant de produire un rouleau de mise en peinture, qui présente un corps de cylindre en mousse synthétique comportant un évidement intérieur permettant de le placer sur un étrier support. Ce rouleau se caractérise en ce que le corps du cylindre est moussé dans un outil de moulage. A cet effet, la pression de moussage est ajustée de manière à former sur la surface supérieure extérieure dudit corps de cylindre et/ou sur la paroi de l'évidement intérieur, une pellicule fermée compactée du matériau plastique, de préférence de la mousse polyester-polyuréthane. Dans une étape ultérieure du procédé, la pellicule est ouverte au moins en partie ou éliminée.
