A method of manufacturing paint roller covers is disclosed in which the paint roller covers are manufactured from a seamless, tubular knitted pile fabric sleeve that is installed onto a core member. To facilitate the manufacture of the paint roller covers, the outside of the core member is provided with an adhesive bonding material on the exterior surface thereof that has a relatively non-tacky outer surface. The knitted pile fabric sleeve is installed onto the exterior surface of the core member over the adhesive bonding material. The adhesive bonding material is then rendered tacky, whereupon the knitted pile fabric sleeve becomes adhesively secured by the adhesive bonding material to the exterior surface of the core member. The pile fabric covered core member 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.

1. A method of manufacturing a paint roller cover, comprising: providing an adhesive bonding material on an outer surface of a tubular core member having a first outer diameter and an interior having a first inner diameter, whereby at least the outer surface of said adhesive bonding material is rendered substantially non-tacky;placing a tubular knitted pile fabric sleeve having a first end and a second end, a pile side with pile extending outwardly, the pile side having a plurality of pile fibers extending outwardly therefrom a distance of between approximately three-eighths of an inch and four inches in length, and a backing side which is opposite said pile side, onto said outer surface of said tubular core member having said adhesive bonding material thereupon with its pile side out, said tubular knitted pile fabric sleeve having a second inner diameter prior to its placement onto said tubular core member; andsubsequently causing said adhesive bonding material to become tacky, whereupon said tubular knitted pile fabric sleeve becomes secured to said outer surface of said tubular core member by said adhesive bonding material; wherein the pile side is configured to apply paint to a worksurface. 2. A method as defined in claim 1, wherein said providing an adhesive bonding material step comprises: placing a segment of dry adhesive film onto said outer surface of said tubular core member. 3. A method as defined in claim 2, wherein said dry adhesive film is heated after it has been placed onto said outer surface of said tubular core member to cause said dry adhesive film to become adhered to said tubular core member, said dry adhesive film then cooling to become non-tacky. 4. A method as defined in claim 2, wherein said dry adhesive film has a pressure-sensitive adhesive located on a side of said dry adhesive film which faces said outer surface of said tubular core member to adhere said dry adhesive film to said tubular core member, an opposite side of said dry adhesive film being non-tacky until it is heated. 5. A method as defined in claim 2, wherein between one and seven turns of said dry adhesive film are placed onto said outer surface of said tubular core member. 6. A method as defined in claim 2, wherein said dry adhesive film is between approximately 0.0005 inches (0.0127 millimeters) and 0.01 inches (0.254 millimeters) thick. 7. A method as defined in claim 1, wherein said providing an adhesive bonding material step comprises: applying a hot melt adhesive onto said outer surface of said tubular core member. 8. A method as defined in claim 1, wherein said adhesive bonding material is rendered substantially non-tacky by cooling said adhesive bonding material. 9. A method as defined in claim 1, wherein said tubular knitted pile fabric sleeve comprises a backing that includes a fiber that is made at least in part with a material having a lower melting point than the rest of the tubular knitted pile fabric sleeve. 10. A method as defined in claim 1, wherein said tubular knitted pile fabric sleeve has an inner diameter that is slightly larger than, approximately the same size as, or smaller than the outer diameter of said core member. 11. A method as defined in claim 1, wherein said tubular knitted pile fabric sleeve and said tubular core member are both substantially longer than the length of a paint roller cover. 12. A method as defined in claim 11, additionally comprising: cutting the assembly comprising said tubular knitted pile fabric sleeve secured to said tubular core member into a plurality of unfinished paint roller covers each covered with knitted pile fabric having pile extending outwardly therefrom and each having edges located at opposite ends thereof. 13. A method as defined in claim 1, wherein said tubular core member is the length of a paint roller cover and wherein said tubular knitted pile fabric sleeve approximately the same length as or slightly longer than said tubular core member. 14. A method as defined in claim 1, wherein said causing said adhesive bonding material to become tacky step comprises: heating said adhesive bonding material to cause it to melt, said adhesive bonding material securing said tubular knitted pile fabric sleeve to said outer surface of said tubular core member when said adhesive bonding material solidifies upon the cessation of heating of said adhesive bonding material. 15. A method as defined in claim 14, wherein said tubular core member is placed upon a mandrel that is heated to cause said adhesive bonding material to melt. 16. A method as defined in claim 14, wherein said tubular knitted pile fabric sleeve and said tubular core member having said adhesive bonding material thereupon are placed into an oven to heat said adhesive bonding material to cause it to melt. 17. A method as defined in claim 14, wherein thermal radiation is directed onto said tubular knitted pile fabric sleeve to heat said adhesive bonding material to cause it to melt. 18. A method as defined in claim 14, wherein said adhesive bonding material comprises a hot melt adhesive. 19. A method as defined in claim 1, wherein said tubular knitted pile fabric sleeve secured to said tubular core member has pile extending outwardly therefrom and also has edges located at opposite ends thereof, said method additionally comprising: combing said pile of said knitted pile fabric secured to said tubular core member;shearing said pile of said knitted pile fabric secured to said tubular core member to the desired length;beveling said edges of said knitted pile fabric secured to said tubular core member; andvacuuming said pile of said knitted pile fabric secured to said tubular core member. 20. A method as defined in claim 1, additionally comprising: cutting said knitted pile fabric secured to said tubular core member into a plurality of unfinished paint roller covers each of a desired length;combing said pile of said knitted pile fabric on said unfinished paint roller covers;shearing said pile of said knitted pile fabric on said unfinished paint roller covers to the desired length;beveling said edges of said unfinished paint roller covers; andvacuuming said pile of said unfinished paint roller covers. 21. A method as defined in claim 1, wherein said core member is formed from at least one winding of said adhesive bonding material. 22. A method as defined in claim 1, wherein the tubular knitted pile fabric sleeve is an uninverted tubular knitted pile fabric sleeve manufactured with its pile side out.
