Formteil mehr Wasser verdampft wird. Die Abstimmung der durch die Formwand fließenden Wassermenge auf die Ausbildung eines optimalen Dampfpolsters istMolding more water is evaporated. The coordination of the amount of water flowing through the mold wall is on the formation of an optimal vapor cushion

Es ist daher Aufgabe der im Anspruch 1 angegebenenIn the production of hollow glass it is necessary, not possible over a longer period of time, so that the preforms in particular change at time intervals on the basis of the requirements for the production of the glass countermolding surface with a lubricant and / or level, and thus the quality is impaired. Treat release agent to result in sticking between ben and increased labor,
Avoid hot glass and mold material. It is therefore the task of the one specified in claim 1

In particular Serungen brought, so that in the majority of the 25 should be an even allocation of the lubricant and / or common glass processing machines the separating agent for the forming surface with respect to layer is still applied by hand. Thereby time and amount can be achieved. This can go through the operator is under high stress due to the different thicknesses of the mold wall distributing the Heat, noise and dirt. In addition, this results in the means to be influenced.
