Methods and apparatus for making paint roller covers by spirally wrapping a strip of hot thermoplastic film onto an exterior surface of a thermoplastic tubular form and spirally wrapping fabric strip having a thermoplastic backing onto the spiral wound strip of thermoplastic film while the thermoplastic film is still sufficiently hot to cause the thermoplastic film to flow into interstices in the fabric backing and permanently bond the fabric strip to the exterior surface of the tubular form. The tubular form may either comprise a plurality of preformed tubes or be formed by spirally wrapping a continuous length of core strip material around a mandrel while maintaining the adjacent edges of the core strip material in closely spaced, nonoverlapping relation to form a spiral seam between the core strip edges. In the latter case, the adjacent edges of the hot thermoplastic film may be overlapped outwardly of the spiral seam to provide additional adhesive at the spiral seam for flow into the spiral seam and into the interstices in the fabric backing outwardly of the spiral seam.
