PURPOSE: To conduct vacuum-application of contour conformable film to surface of article by securing film between the first and second pressure chambers, evacuating the both chambers, letting contact face of the film touch the surface to be applied, and increasing pressure in the second pressure chamber. CONSTITUTION: Vacuum application apparatus 100 has the first and second pressure chambers 102 and 104. The both pressure chambers, 102 and 104, are separated with film 30 as pressure resistant seal of passage with means 108 to secure the film 30 across the passage between the both chambers. Specific orientation is given to the film 30 so that its contact face 32 faces the article 5. The first and second pressure chambers, 102 and 104, are evacuated so as to maintain the same pressure. As pressure in the second chamber 104 is raised and the film 30 is expanded into the first chamber 102, the film 30 can be secured in such a manner as reducing necessary expansion when closely conformed to contour of stuck face 10 of the article 5. |
