| 20090320994 | METHODS FOR MANUFACTURING A PAINT ROLLER WITH PERFORATED SUBSTRATE - A method for reducing cost and weight in paint roller manufacturing processes and other continuous processes for producing tubular goods from polymers. The method may utilize a perforated substrate such as a perforated polypropylene strip or may include a perforating step which removes overage from an unperforated substrate. An unperforated substrate, which may be of a thinner gauge than the perforated substrate, is fed onto a mandrel. The perforated substrate is fed onto the unperforated substrate to form a tube. Adhesive is applied upon the outer surface of the perforated substrate. A cover may be applied about the tube, and the resulting product is then cut into finished-size paint rollers. The removal of the overage results in a reduction in the weight of the paint roller. In certain embodiments the overage from a perforation step is collected, and may be reused in a subsequent implementation of the method or resold. | 12-31-2009 |
| 20100170629 | METHODS FOR MANUFACTURING A PAINT ROLLER AND COMPONENT PARTS THEREOF - Described is a method of making a non-porous composite cover material formed of a pile material and an adhesive layer made from polypropylene or predominantly from polypropylene. A width of the pile material is advanced, and a layer of adhesive is applied thereupon. The adhesive is allowed to set, and the width of material is longitudinally cut into strips of composite cover material. Laminated paint rollers are thereafter made by helically one or two strips of polypropylene or strips made predominantly of polypropylene about a mandrel and applying a layer of adhesive made from polypropylene or predominantly from polypropylene on the strip or strips, and applying a non-porous composite cover material. A compressive force is applied upon the outer surface of the composite cover material to urge the composite cover material, the layer of adhesive and strip or strips of thermoplastic material together against the mandrel, thereby laminating the inner surface of the composite cover material and the strip or strips together and forming a continuous product that can be cut and finished to make paint rollers. | 07-08-2010 |
| 20100170630 | METHODS FOR MANUFACTURING A PAINT ROLLER AND COMPONENT PARTS THEREOF - 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. | 07-08-2010 |
| 20100282400 | METHODS FOR MANUFACTURING A PAINT ROLLER AND COMPONENT PARTS THEREOF - Described are methods of making a paint roller from a compound of polypropylene and calcium carbonate having between 5% and 50% calcium carbonate by weight, and, in an embodiment, between 25% and 40%. One or various compounds may be used to form portions of, or all of the components that make up the paint roller, including, for example, the thermoplastic strips, adhesives and/or the backing of a composite cover material. The materials can be assembled in a continuous manufacturing process. | 11-11-2010 |
| 20100282401 | METHODS FOR MANUFACTURING A PAINT ROLLER AND COMPONENT PARTS THEREOF - Described are methods of making a paint roller using an adhesive made from a compound of polypropylene and calcium carbonate having between 5% and 66% calcium carbonate by weight. Described are methods of making a paint roller using preformed strips or core material made from a compound of polypropylene and calcium carbonate having between 5% and 66% calcium carbonate by weight. Described are methods of making a paint roller using a composite cover material made from a compound of polypropylene and calcium carbonate having between 5% and 50% calcium carbonate by weight. One or various compounds may be used to form portions of one or multiple components that make up the paint roller, including, for example, the thermoplastic strips, adhesives and/or the backing of a composite cover material. The materials can be assembled in a continuous manufacturing process. | 11-11-2010 |
