Abstract

The blank (13) takes the form of a flat disc or fibrous, non-elastic material, e.g. a cardboard disc. The shell can have one or more external concave side areas, and the blank is impressed with bending lines located between each of the concave side areas and its centre. The bending lines are formed and located parallel to the concave level lines comprising the cutting lines between the shell and the plane at right angles to the direction relative to the shell of the movable tool in the final stage of pressing.
