Abstract

A process for manufacturing a hollow glass body by means of an individual section (IS) machine in a press and blow, narrow-neck press and blow, or blow and blow process, with a driving means that moves a plunger axially, to produce selected geometrical contours in a glass gob. The process steps include:

aligning and attaching a positioning ring directly, or via intermediate elements, on the IS machine, on which positioning ring a positioning device is provided,aligning a guide tube, on an outer jacket surface on which a guide device is disposed and interacts with the positioning device of the positioning ring in the assembled condition,aligning a plunger with a non-rotationally symmetrical plunger head with a guide device disposed thereon , which interacts with a positioning device provided in the assembled condition on, or in, the inner jacket surface of the guide tube such that the non-rotationally symmetrical outer contour of the plunger head passes through an aperture tool allocated to the IS machine during the press or blow procedure, and the contours of the plunger head and of the aperture tool generate the profile of the inner, or outer, wall of the hollow glass body.
