摘要： A paint roller manufacturing system and method are described. In an embodiment, an inner strip of material and an outer strip of material are wound about a mandrel in offset relation. The inner strip of material and the outer strip of material each comprise material that results in a final paint roller which shrinks by less than 2.5 percent of the final paint roller axial length, or which has shrinkage that varies by less +/−0.1%, upon hardening and setting. An adhesive is applied to at least a portion of the outer strip as it is wound about the mandrel. A length of fabric is wound about at least the outer strip to form a paint roller tube, and compression is applied to the paint roller tube while advancing the paint roller tube in a direction parallel to the mandrel. A precision measuring or sensing device is used to control a cutting device causing the cutting device to cut the advancing paint roller tube into pre-selected lengths prior to the paint roller tube hardening and setting.

摘要： Described is a method of making a laminated paint roller wherein a perforated strip of thermoplastic material is advanced, the perforated strip having holes there-through. A lubricant is applied to the inner surface of the advancing perforated strip of thermoplastic material. The lubricated, perforated strip of thermoplastic material is helically wound around a cooled mandrel so as to form a helically wound strip wherein the inner surface of the perforated strip faces the cooled mandrel and the outer surface of the perforated strip faces away from the cooled mandrel. The wound perforated strip is advanced along the cooled mandrel. A layer of adhesive is applied onto an outer surface of the wound perforated strip. A strip of composite cover material is helically wrapped about the wound strip and over the layer of adhesive, the outer surface of the composite cover material comprising a pile fabric, and the inner surface of the composite cover material comprising thermoplastic. A compressive force is applied upon the composite cover material to urge the composite cover material, the layer of adhesive and strip of thermoplastic material together against the cooled mandrel, thereby laminating the inner surface of the composite cover material to the outer surface of the strip. A method of making a composite cover material is also disclosed.

摘要： A method for improving strength of the finished product in paint roller manufacturing processes and other continuous processes for producing tubular goods from polymers. The method utilizes a substrate such as a polypropylene strip with grooves on its surface. The grooved substrate is fed onto a mandrel to form a tube. Adhesive is applied upon the grooved surface of the grooved substrate. A cover may be applied about the tube, and the resulting product is then cut into finished-size paint rollers. The hardened adhesive in the grooves may operate to reduce the hoop-force which would otherwise tend to unwind the wound substrate. The method in certain embodiments provides a reduction in cost and weight of the finished product.

摘要： 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; advancing a second strip of polypropylene about a mandrel in offset relation to the first strip; advancing a cover about the second strip of polypropylene; providing a first adhesive layer (preferably a liquefied polypropylene) between the first and second strips of polypropylene; providing a second adhesive layer between the second strip of polypropylene and the cover; 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, thereby creating the continuous laminated paint roller. After forming of the continuously paint roller it is moved towards a cutter by a helical drive belt system. The continuously formed roller is then preferably cut into lengths for movement to a finishing station, and then cut into finished size paint rollers.

摘要： In an embodiment, a paint roller manufacturing system and method uses a fabric-coating applicator to apply a fabric adhesive onto a portion of a perforated paint roller cover fabric material having a plurality of perforations through which adhesive may flow, and into the plurality of perforations and into interstitial spaces of the fabric material, to yield a length of coated fabric. An inner strip and an outer strip are wound about a mandrel in offset relation. A strip-coating applicator is used to apply a strip adhesive to the outer strip as it is wound about the mandrel. Simultaneously with the step of applying the strip adhesive to the outer strip, a portion of the coated paint roller fabric material is received at the outer strip and the length of coated fabric is wound about at least the outer strip to form a paint roller tube.
