A method and an apparatus for manufacturing hollow glass objects according to the press-and-blow process, in which a glass gob is shaped in a cooled preform mould into an elongate parison, the parison, while freely hanging at its neck portion, is then subjected to a thermal intermediate treatment and subsequently the parison is blown up in a finish mould to the desired hollow glass object and is simultaneously subjected to an upsetting operation, in such a manner that the blown-up hollow glass object at the part having larger transverse dimensions has a considerable wall thickness.
