Abstract
A method and device for the manufacture of a hollow cone ( ) with a cone tip ( ) whereby a parison of viscous material ( ) is moulded into the shape of the hollow cone. An escape space ( ) becomes accessible to the material in the vicinity of a cone tip to be formed. The moment the pressure present in the material in the vicinity of the cone tip to be formed exceeds a previously defined value. Breaking-off of the cone tip during or after moulding is prevented by this. The hollow cone is suitable inter alia for use in a cathode ray tube.
