Abstract:
1. A roller cover support assembly comprising a roller cover support mountable for rotation on a roller frame shaft, and an annular retention spring coupled to the roller cover support, the retention spring including a plurality of axially extending circumferentially spaced resiliently deformable transversely convex arcs, the convex arcs having an axial length corresponding to a substantial majority of the axial length of the retention spring, the convex arcs having peaks engageable with an inner diameter of a roller cover when forced over the retention spring for frictionally retaining the roller cover on the roller cover support, wherein the peaks of the convex arcs have an axial length of substantially the same outer radius throughout a substantial majority of the length of the convex arcs for increasing the frictional contact between the peaks of the convex arcs and the inner diameter of the roller cover over the length of the peaks when the roller cover is forced over the retention spring, wherein the convex arcs have an axial length that is interconnected throughout their length by concave arcs between the convex arcs.
