BRIEF SUMMARY
CROSS-REFERENCE TO RELATED APPLICATIONS
The method and apparatus disclosed herein relates to commonly assigned application Ser. No. 07/036,659 filed Apr. 10, 1987 now U.S. Pat. No. 4,763,392 and entitled METHOD OF MANUFACTURING A TOTALLY COATED TIRE RIM in the names of Robert D. Fogel and Albert A. Tabor, and the totality of the disclosure of the latter-identified application is incorporated herein by reference.
BACKGROUND OF THE INVENTION
The present invention is directed to refinishing or reconditioning rims or wheels of motor vehicles, such as trucks, automobiles, tractors, trailers, or the like.
A truck rim is very rarely serviced from the day a tire is first mounted thereon and any number of retreads or new tires are remounted thereon. Such truck rims or wheels are subject to virtually constant use under most adverse coditions of nature, terrain and the like. Quite simply, the more commercial vehicles are used or are "on the road," the more profitable is the return on investment. Accordingly, the wheels and rims are normally removed from trucks, tractors, trailers, or the like, new tires or retreads are mounted thereon, and these rims and wheels are returned to service with most unfortunate consequences, as evidenced by recent national reports confirming the high incidents of large vehicle accidents in proportion to the lesser number of such vehicles on the road as compared to passenger automobiles. If a truck wheel or rim is not cleaned, refurbished and/or refinished or is not even incidentally inspected before being returned to service, the truck upon which the rim or wheel is mounted is a potential rolling disaster. Accordingly, the present invention provides a novel method of and apparatus for refinishing truck or similar vehicle wheels and rims so that when remounted with retreads or new tires on vehicles, the safety factor of the refinished rims and/or wheels are comparable and even better than when new.
SUMMARY OF THE INVENTION
The present invention is directed to a novel method of and apparatus for refinishing truck or similar wheels and rims by rotating a rim/wheel in a first chamber and subjecting the same to a hot high-pressure water spray for cleaning and degreasing purposes, transferring the rim/wheel to a second chamber in which the rim/wheel is again rotated and shot-blasted to remove dirt, rust, debris and paint therefrom, removing the rim/wheel from the second chamber, and thereafter applying a complete coating of polymeric protective material upon the rim/wheel whereby a retread or a new tire applied thereto will be assured of safety and performance, extended wear and service life and low future maintenance, all accomplished in a matter of minutes at low costs.
In further keeping with this invention, the rim/wheel is preferably rotated in both chambers when its axis is disposed in a generally horizontal plane and the coating of polymeric material is applied by spraying when the rim/wheel is disposed in two positions with the axis thereof respectively vertical and horizontal.
Another object of this invention is to provide a novel refinishing method and apparatus in which the rim/wheel is elevated from floor level over an arcuate path of travel to the first chamber, conveyed from the first chamber to the second chamber, painted and subsequently relowered along an arcuate path back to floor level.
Still another object of this invention is to provide a novel refinishing method and apparatus as aforesaid wherein an ejection mechanism is utilized with each chamber to effectively eject each rim/wheel by rotation thereof along its axis.
With the above and other objects in view that will herein after appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.
