Abstract
The disclosure describes an improved paint roller wherein ribs are incorporated into either the roller core or the nap. Alternatively, the improved paint roller may use individual ribs positioned between the roller core and the nap. The incorporation of ribs into the roller core/nap assembly improves application of coating material to the nap and subsequent transfer of coating material to a surface.
