<p>A roller cover support assembly includes a roller cover support mountable for rotation on a roller frame shaft and a resiliently deformable annular retention spring including a plurality of circumferentially spaced convex arcs having peaks engageable with the inner diameter of a roller cover when forced over the retention spring for frictionally retaining the roller cover on the roller cover support. These peaks may have an axial length for increasing the frictional contact between the convex arcs and inner diameter of the roller cover when forced over the retention spring and inwardly tapered outboard ends for ease of forcing the roller cover over the retention spring. The convex arcs may be interconnected by concave arcs between the convex arcs at respective tangent points of the arcs.</p> |
