ABSTRACT:
In a process for shaping a gob in order to obtain a hollow glass article by means of an electronically-regulated and hydraulically-propelled level, the process of shaping the gob into a rough or finished product is rationally effected in a predefinable and in particular precisely reproducible manner by the fact that an electro-hydraulic servo-drive is used as a means for driving the level, and that the latter, during at least the practically total performance of the movement, is adjusted in position by means of a closed position-regulating circuit. In a device suited for this purpose the drive device of the level consists of an electro-hydraulic servo-drive and an electronic position-adjusting device for the at least approximately total movement of the level. Preferably the movement of the level in the glass article is also effected at a regulated speed and, ideally, the shaping stage is completed by a pressure-regulated forward movement of the level.
