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 .
