Paint roller cover support includes a cage assembly mounted for rotation and limited axial movement in opposite directions on the shaft portion of a roller frame. The cage assembly includes a plurality of circumferentially spaced axially extending semi-cylindrical sleeve segments that move radially outward and inward relative to the shaft portion during axial movement of the cage assembly in opposite directions. Elastomeric rings surrounding opposite ends of the sleeve segments maintain cam members on the sleeve segments in engagement with cam lifters on respective hub members on the shaft portion. Both the elastomeric rings and elastomeric material attached to radial outer surfaces of the sleeve segments may be pressed into frictional engagement with the inner diameter of a surrounding roller cover during radial outward movement of the sleeve segments for securely retaining the roller cover on the support.

Le support de revêtement de rouleau de peinture selon linvention comprend un ensemble cage monté afin de permettre une rotation et un mouvement axial limité dans des directions opposées sur la partie de manche d'une structure de rouleau. L'ensemble cage comprend une pluralité de segments de manchon semi-cylindriques sétendant axialement et espacés sur le plan circonférentiel, qui se déplacent radialement vers lextérieur et vers lintérieur par rapport à la partie de manche pendant le mouvement axial de lensemble cage dans des directions opposées. Des bagues élastomères entourant les extrémités opposées des segments de manchon maintiennent des éléments de came sur les segments de manchon en prise avec des dispositifs de levage de came sur des éléments de moyeu respectifs sur la partie de manche. Aussi bien les bagues élastomères que le matériau élastomère fixé sur les surfaces externes radiales des segments de manchon peuvent être pressés en contact frictionnel avec le diamètre interne d'un revêtement de rouleau alentour pendant le déplacement radial vers l'extérieur des segments de manchon afin de fixer solidement le revêtement de rouleau sur le support.
