| 20080271669 | POLYMERIC COVER FOR ROBOTS HAVING AN INCREASED TOTAL SURFACE ENERGY - The present invention involves cover for robots having spray nozzles wherein the surface material of the covers have been enhanced for residue retention. The robot covers of the present invention may be formed from a polymer, which in one exemplary embodiment may be polyethylene. For example, the polymer may be received in the form of a cast or blown extruded plastic film. In one exemplary embodiment, the polymer may be processed to increase the surface energy and/or surface area of the polymer. By increasing at least one of the surface energy and the surface area of the polymer, the total energy of the surface of the polymer is increased. | 11-06-2008 |
| 20080237921 | POLYMERIC COVER FOR ROBOTS - The present invention involves a cover for a spraying device of a robot which is formed from a polymer with enhanced residue retention properties. The polymer may be processed to increase the surface energy of the polymer. For example, the polymer may be subjected to a corona treatment in order to increase its surface energy. The corona treatment process may be performed on the polymer as received, prior to cutting or otherwise manipulating the polymer. Also, the polymer may be embossed to provide the enhancement. To assemble the polymer into a robot cover, the polymer as received may be cut into individual sections for assembly. The sections may then be assembled to one another by heat sealing the sections together. The heat sealing provides a bond between the individual sections of polymer that secures the individual sections together to create the robot cover. The polymer may also be formed into tubular sections for securing to the spraying device. | 10-02-2008 |
