Process for producing a blown glass body comprises determining the position of the surface of a glass melt in an adjusting position of an immersion tube, controlling the position, and bombarding the immersion tube with a blowing pressure

摘要

Process for producing a blown glass body comprises: determining the position of the surface (42) of a glass melt (8) in an adjusting position of an immersion tube (10); controlling the position so that the immersion tube with its free end is immersed above a prescribed immersion depth (h) and removing the tube with a predetermined amount of glass; and bombarding the immersion tube with a blowing pressure. An Independent claim is also included for a device for producing a blown glass body, comprising a glass melting unit (4), an immersion tube (10), a unit (40) for determining the position of the glass melt surface, an adjusting unit (18) for lowering, immersing and removing the immersion tube into and out of the glass melt, a pump (26), and a computer-controlled control unit (22) for controlling the adjusting unit.
