<p>A reusable multi-strip laminate paint roller and method for manufacturing the same. The method comprising steps of advancing a first strip of polypropylene material about a mandrel (21); advancing a second strip of polypropylene about a mandrel in offset relation to the first strip (22); advancing a cover about the second strip of polypropylene (23); providing a first adhesive layer (preferably a liquefied polypropylene) between the first and second strips of polypropylene (6); providing a second adhesive layer between the second strip of polypropylene and the cover (6); and applying a compressing force upon the cover urging the cover toward the second strip and simultaneously urging the second strip toward the first strip (2, 23) thereby creating the continuous laminated paint roller. After forming of the continuous paint roller it is moved towards a cutter by a helical drive belt system (2). The continuously formed roller is then prefeably cut into lengths for movement to a finishing station, and then cut into finished sizepaint rollers.</p> |
