ABSTRACT:
An improved pressing machine for hollow glassware comprising advancing means for advancing molds through a series of advance steps for molding one range of size of articles and for advancing the molds through advance steps of other distances for molding articles of other size ranges. For each size range of articles to be produced, the machine includes a group of glass discharging devices discharging molten glass into each of the molds and a plurality of pressing devices for molding the glass within the molds. These devices are spaced relative to each other by distances equal to the distance of advance of the molds from station to station. The pressing machine further includes a molding plate having an adaptor for mounting molds of different sizes depending on which range of sized articles are to be produced.
