Abstract: A device for locating at least one edge of a flexible film and designed to present the film in a specific position and in a natural state of tension with no appreciable elongation. The device comprises a plate against which the edge rests, a pair of rollers adapted to grip the film resiliently and to keep it against the plate and stiffening plates 4 and 5 which are curved for the purpose of increasing the moment of inertia of the film in the locating area. The device may be used in the manufacture of balloons of synthetic material made from flexible films.
