Abstract

The invention relates to a method and an apparatus for stretching film. The film 3 is placed between two advantageously annular frame parts 1, 2. In addition, an elastic piece 4 has been placed at least between the second frame part 1, 2 and the film 3, which elastic piece touches the frame parts when they are pressed one against the other. <IMAGE>
