<p>The method involves placing a protective film (1) on the surface of an upper tool (2,3), where the surface design of the upper tool represents a negative form of the surface, which is protected. The protective film is fixed in its position by a vacuum, which is generated between the upper tool and the protective film. A relative movement takes place by upper tool or by the object, such that the upper tool is positioned over the surface of the object.</p> |
