PATENT. ANSPRUCH :
Verfahren zur Herstellung von Glashohlgogenstünden, insbesondere von Glasröhren, dadurch gekennzeichnet, dass die in einer Vorform mit beweglichem Boden und durchbohrtem Press-Stempel in bekannter Weise vorgeformte Glasmasse nach Entfernen des Untertheilos der Form durch gleichzeitiges Senken des beweglichen, die Glasmasse festhaltenden Bodens und Einführens von Prossluft durch den durchbohrten Press-Stempel zu einem Hohlkörper ausgezogen wird.
PATENT. CLAIM :
A method for the production of glass hollow sections, in particular glass tubes, characterized in that the glass mass, pre-formed in a known manner in a preform with a movable bottom and a pierced press punch, after removing the lower part of the form by simultaneously lowering the movable bottom holding the glass mass and introducing Prossluft is pulled out through the pierced press plunger to form a hollow body.
