A film dispenser and a film retriever are provided and preferably they move cooperatively in at least two dimensions with respect to the part holder. The film has a first edge and a second edge, and the film can be a decorative coating, a protective coating or combinations of these. The film dispenser holds the first edge of the film, the film is positioned between the mandrel and the part holder and the film retriever holds the film second edge. ## Claims ### Claim 1 A method for coating a part comprising an asymmetrical edge comprising the steps of: a. attaching the part to a part holder; b. placing a film between the part and a mandrel; c. rolling the part over the mandrel such that the asymmetrical edge of the part contact the film; and, d. moving one or both of the mandrel and the part holder in an angular relationship to one another as the angle of the part's asymmetrical edge changes. ### Claim 2 (depends on 1) The method of claim 1, wherein the film has a first edge and a second edge, and wherein the film is a decorative coating, a protective coating or combinations of these. ### Claim 3 (depends on 2) The method of claim 2, wherein the film is a multi-layered film comprising a carrier, a release compound, a metallic foil and an adhesive. ### Claim 4 (depends on 2) The method of claim 2, wherein a film dispenser holds the first edge of the film and a film retriever holds the second edge of the film and the film dispenser and the film retriever move co-operatively in at least two dimensions with respect to the part holder. ### Claim 5 (depends on 4) The method of claim 4, wherein the film dispenser and the film retriever move cooperatively in at three dimensions with respect to the part holder. ### Claim 6 (depends on 4) The method of claim 4, wherein the both the film dispenser and the film retriever rotate to move the film laterally between the mandrel and the part holder. ### Claim 7 (depends on 3) The method of claim 3, wherein the asymmetrical edge of the part is in physical contact with a coating side of the film and the mandrel is in contact with a release side of the film. ### Claim 8 (depends on 7) The method of claim 7, wherein as the part rotates against the mandrel the protective or decorative layer is deposited onto the asymmetrical edge of the part. ### Claim 9 (depends on 4) The method of claim 4, wherein the film dispenser and the film retriever move cooperatively in at least two dimensions with respect to the part holder as the part is rotated to relieve stress on the film as the asymmetrical edge of the part changes angle. ### Claim 10 (depends on 5) The method of claim 5, wherein the film dispenser and the film retriever move cooperatively in three dimensions with respect to the part holder as the part is rotated to relieve stress on the film as the asymmetrical edge of the part changes angle. ### Claim 11 (depends on 6) The method of claim 6, wherein the film dispenser and the film retriever rotate continuously while the part is rotated to continuously feed film between the part and the mandrel. ### Claim 12 (depends on 6) The method of claim 6, wherein the film dispenser and the film retriever are stationary while the part is rotated and rotate after a part is coated to provide a fresh film surface. ### Claim 13 (depends on 1) The method of claim 1, wherein the mandrel rotates and is heated. ### Claim 14 (depends on 1) The method of claim 1, wherein the mandrel rotates and is deformable. ### Claim 15 (depends on 1) The method of claim 1, further comprising the step of applying a label or a decal to the part. ### Claim 16 (depends on 1) The method of claim 1, wherein the part is selected from the group consisting of, a bottle, a jar, an over cap, a pump, a lid, a consumer product and mixtures thereof. ### Claim 17 (depends on 1) The method of claim 1, wherein the part is high gloss molded.
