Abstract
A tooling device for making a plastic film component. The tooling device includes a molding tool having a molding part, a receptacle, an opening and closing device, and at least one covering device having a covering surface and guide arrangement. The molding part and the receptacle are movable relative to each other between a closed and an open position. Relative movement between the molding part and the receptacle to the closed position is transmitted to the covering device to move it from an exposed position, in which the covering surface is spaced from an inner surface of the molding part, to a covered position, in which the covering surface covers a covered section of molding part's inner surface.
