Abstract
Abstract Method and apparatus for coating irregular and/or small regular parts such as for example, turbine blades. Apparatus features a workpiece spindle carrying member mounted on a base, a plurality of workpiece spindles mounted on the carrying member, means for rotating the carrying member and other means for rotating the workpiece spindles, means correlating the speed and direction of rotation of the carrying member and the workpiece spindles. Method includes the steps of depositing coating material on the workpiece as the parts translate and rotate past a device for depositing coating material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
A method for coating objects comprising (a) rotating said object about a longitudinal axis; (b) rotating said longitudinal axis about a second axis spaced from and parallel to said longitudinal axis so as to provide translation and rotation of said objects; (c) correlating the speed and direction of rotation of said longitudinal axis and said second axis; (d) providing a spray coating device in proximity to said objects for depositing coating material thereon; (e) depositing coating material on said object as it moves past said spray coating device; (f) continuing the translation and rotation of said object past said spray coating device until the desired coating is achieved.
Claim 2
Independent Claim
108 words
A method for coating objects comprising (a) rotating said object about a longitudinal axis; (b) rotating said longitudinal axis about a second axis spaced from and parallel to said longitudinal axis so as to provide translation and rotation of said objects; (c) correlating the speed and direction of rotation of said longitudinal axis and said second axis; (d) providing a spray coating device in proximity to said objects for depositing coating material thereon; (e) depositing coating material on said object as it moves past said spray coating device; (f) continuing the translation and rotation of said object past said spray coating device until the desired coating is achieved.
Claim 3
Dependent Claim
12 words
A method according to claim 1 wherein said objects are turbine vanes.
Claim 4
Dependent Claim
12 words
