- 12. An apparatus for applying a coating of material to discontinuous cylindrical portions of a part comprising:a rotatable wheel having a cylindrical wall with at least one aperture extending therethrough for applying a coating of material onto an applicator surface; and a rotatable support member for holding a part to be coated and for transferring the coating of material carried by the applicator surface to a surface of the part to be coated, the applicator surface movable synchronously with respect to the discontinuous cylindrical portions of the part to be coated in order to bring the coating of material into contact with the discontinuous cylindrical portions to be coated.
- 13. The apparatus of claim 12 further comprising:means for at least partially curing the coating of material carried on the applicator surface.
- 14. The apparatus of claim 13 wherein the curing means is selected from a group consisting of forced air, conductive heating, convection heating, radiant heating, applied heating, reflective heating, microwave heating, ultraviolet light, infrared heating, chemical evaporation, chemical catalyst, chemical acceleration agent, chemical activator agent, and combinations thereof.
- 15. The apparatus of claim 12 further comprising:a wiper arm engageable with an interior surface of the cylindrical wall for spreading the coating of material to be applied through the at least one aperture.
- 16. The apparatus of claim 12 wherein the applicator surface further comprises:a moveable surface engageable with the applying means at a receiving position and engageable with the part to be coated at a transferring position.
- 17. The apparatus of claim 16 further comprising:a rotatable member supporting the applicator surface for movement along a fixed closed path of travel between the receiving position and the transferring position.
- 18. The apparatus of claim 12 further comprising a source of material to be coated on the part, wherein the coating of material to be applied is a low friction material.
- 19. The apparatus of claim 12 further comprising means for synchronously moving the part to be coated with respect to the applicator surface, wherein the part to be coated is a piston.
- 20. A method for applying a coating of material to discontinuous cylindrical portions of a part comprising the steps of:applying a coating of material onto an applicator surface through an aperture extending through at least one wall allowing passage of the coating material onto the applicator surface; and transferring the coating of material carried by the applicator surface to a surface of a part to be coated as the applicator surface moves synchronously with is respect to the discontinuous cylindrical portions of the part to be coated in order to bring the coating of material into contact with the discontinuous cylindrical portions to be coated.
- 21. The method of claim 20 further comprising the steps of:at least partially curing the coating of material carried on the applicator surface.
- 22. The method of claim 21 wherein the curing step is selected from a group consisting of blowing forced air, conductive heating, convection heating, radiant heating, applied heating, reflective heating, microwave heating, ultraviolet light heating, infrared heating, chemical evaporation, chemical catalyst reacting, chemical accelerating agent, chemical activating agent, and combinations thereof.
- 23. The method of claim 20 wherein the applying step further comprises the step of:rotating a wheel having a cylindrical wall with at least one aperture formed through the cylindrical wall.
- 24. The method of claim 23 further comprising the step of:engaging a wiper arm with an interior surface of the cylindrical wall for spreading the coating of material to be applied through the at least one aperture.
- 25. The method of claim 20 further comprising the step of: supplying the coating of material to be applied to the applicator surface.
- 26. The method of claim 20 wherein the applicator surface further comprises:a moveable surface engageable with the applying means at a receiving position and engageable with the part to be coated at a transferring position.
- 27. The method of claim 26 further comprising the step of:moving the applicator surface along a fixed closed path of travel between the receiving position and the transferring position with a rotatable member.
