<p>Method for shaping a film/sheet, particularly for making three-dimensional shapes in it, in which case the contours of the shape to be formed are warmed/heated and the film/sheet is stretched along the heated contour, in order to cause the part of the film/sheet inside it to deviate from the plane of the surface. The heated contours are created by, for example, directing a focussed, moving beam of thermal radiation onto it.</p> |
