A method of manufacturing paint roller covers is disclosed in which the paint roller covers are manufactured from a seamless, tubular fabric sleeve having a backing or base fabric having pile strands knitted thereinto which pile strands extend outwardly from the base fabric to form the pile of the seamless, tubular fabric sleeve. The seamless, tubular fabric sleeve is placed onto a segment of film wound onto a cylindrical member, and heat is applied to cause the segment of film to fuse with the base fabric to support the seamless, tubular fabric sleeve in a cylindrical configuration. The tubular knitted pile fabric having the segment of film fused thereto may be finished into paint roller covers by combing and shearing the pile fabric to a desired length, beveling the edges of the paint roller covers, and vacuuming stray fibers from the paint roller covers.
