ABSTRACT:
Roller cover support consists of blow molded sleeve having plural protruding ribs to frictionally retain the roller cover in place. The ends of the sleeve are molded to receive and mount end caps thereon which include suitable bearings for the roller frame shaft and provide some support against collapse or flattening out of the sleeve during use under pressure. The O.D. of the end caps and adjacent ends of the sleeve are slightly smaller than the I.D. of the roller cover for normal concentricity and guidance of the roller cover onto the sleeve, and the ends of the ribs are tapered to wedge the roller cover on. When the roller frame shaft extends all the way through the roller support, perforations may be placed along the length of the sleeve to provide for drainage of any water or other liquid that may seep into the interior of the sleeve through the end cap bearings during clean up. However, a Y-shape frame may be used having spaced apart end supports for both ends of the sleeve, so that the end caps may be completely closed to keep water out. Such end supports are preferably substantially flat and parallel to each other and relatively thin so as not to interfere with painting closely adjacent to a corner and the like.
