Abstract: In an apparatus comprised of a ring-shaped nozzle in a nozzle piece, which ring-shaped nozzle has a reciprocally movable nozzle cone piece, wherewith the cone piece and nozzle piece together define a ring-shaped nozzle opening, it is desired to modify the ring-shaped nozzle such that, in the manufacturing of hollow bodies, the amount of scrap can be reduced and the range of practicable applications of the apparatus can be extended. This is achieved in that an additional device or arrangement is provided for closing the nozzle opening. With the improved apparatus, one can achieve improvements in the hollow body being produced, the improvements being attributable to a special technique of closing the ring-shaped nozzle, which technique is enabled by the novel closure device.
