A method of manufacturing paint roller covers is disclosed in which the paint roller covers are manufactured from a seamless segment of tubular paint roller cover fabric that is placed onto a cylindrical forming tube having a segment of bonding material temporarily secured on its outer surface under the segment of tubular paint roller cover fabric. The cylindrical forming tube is placed on a heated mandrel to apply heat thereto to cause the bonding material to bond to the interior of the segment of tubular paint roller cover fabric. The cylindrical forming tube is removed from the mandrel and cooled, and the segment of tubular paint roller cover fabric becomes secured to the bonding material to produce a semi-rigid paint roller cover segment. The semi-rigid paint roller cover segment may be finished into paint roller covers by cutting it into appropriately sized segments, 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 paint roller cover, comprising: a segment of bonding material wound in a cylindrical configuration; anda segment of tubular paint roller fabric having an interior, a first end, and a second end, the segment of tubular paint roller fabric being located over the segment of bonding material; where
1. A paint roller cover, comprising: a segment of bonding material wound in a cylindrical configuration; anda segment of tubular paint roller fabric having an interior, a first end, and a second end, the segment of tubular paint roller fabric being located over the segment of bonding material; wherein the segment of bonding material is configured such that it is heat bonded to the interior of the segment of tubular paint roller fabric in a manner securing the segment of tubular paint roller fabric to the bonding material; and wherein the segment of bonding material is semi-rigid in a manner supporting the segment of tubular paint roller fabric thereupon; and wherein the segment of tubular paint roller fabric comprises pile strands knitted into a backing fabric, and wherein the backing fabric comprises at least one bicomponent fiber comprising: a first material having a first melting point; anda second material having a second melting point that is lower than said first melting point. 2. A paint roller cover as defined in claim 1, wherein the bonding material comprises: a segment of thermally activatable bonding tape wound in helical windings into a cylindrical formation. 3. A paint roller cover as defined in claim 2, wherein the helical windings overlap. 4. A paint roller cover as defined in claim 2, wherein the thermally activatable bonding tape comprises: a polyurethane film material. 5. A paint roller cover as defined in claim 4, wherein the polyurethane film material is reinforced with a support netting material. 6. A paint roller cover as defined in claim 1, wherein the segment of tubular paint roller fabric comprises: a sliver knit tubular knitted pile fabric wherein the pile strands comprise tufts of sliver fibers. 7. A paint roller cover as defined in claim 1, wherein the segment of tubular paint roller fabric comprises: a knit tubular knitted cut pile fabric wherein the pile strands comprise cut pile segments. 8. A paint roller cover as defined in claim 1, wherein the segment of tubular paint roller fabric is substantially longer than the length of a paint roller cover. 9. A paint roller cover as defined in claim 1, wherein said bonding material has been melted onto the interior of the segment of tubular paint roller fabric. 10. A paint roller cover as defined in claim 1, wherein the segment of tubular paint roller fabric has a pile side and a backing side which is opposite said pile side, and wherein the segment of tubular paint roller fabric is manufactured and provided with its pile side out. 11. A paint roller cover as defined in claim 1, wherein the segment of tubular paint roller fabric is substantially longer than the length of a paint roller cover. 12. A paint roller cover as defined in claim 1, additionally comprising: a cylindrical segment of paper, wherein the segment of bonding material is located intermediate the segment of paper and the segment of tubular paint roller fabric. 13. A paint roller cover, comprising: a segment of bonding material helically wound in a cylindrical configuration; anda segment of tubular paint roller fabric located on the helically wound segment of bonding material; whereupon the helically wound segment of bonding material has been heated at a sufficient temperature for a sufficient period of time to cause the bonding material to bond to the interior of the segment of tubular paint roller fabric, and subsequently cooled to cause the segment of bonding material to become semi-rigid, the segment of tubular paint roller fabric being secured to the bonding material; and wherein the bonding material comprises: a segment of thermally activatable bonding tape; and wherein the thermally activatable bonding tape comprises: a polyurethane film material. 14. A paint roller cover as defined in claim 13, wherein the helical windings of the thermally activatable bonding tape overlap. 15. A paint roller cover as defined in claim 13, wherein the segment of tubular paint roller fabric comprises either: a sliver knit tubular knitted pile fabric wherein the pile strands comprise tufts of sliver fibers; ora knit tubular knitted cut pile fabric wherein the pile strands comprise cut pile segments. 16. A paint roller cover as defined in claim 13, wherein the segment of tubular paint roller fabric comprises pile strands knitted into a backing fabric, and wherein the backing fabric comprises at least one bicomponent fiber comprising: a first material having a first melting point; anda second material having a second melting point that is lower than said first melting point. 17. A paint roller cover as defined in claim 13, wherein said bonding material has been melted onto the interior of the segment of tubular paint roller fabric. 18. A paint roller cover as defined in claim 13, wherein the segment of tubular paint roller fabric has a pile side and a backing side which is opposite said pile side, and wherein the segment of tubular paint roller fabric is manufactured and provided with its pile side out. 19. A paint roller cover as defined in claim 13, wherein the polyurethane film material is reinforced with a support netting material.
