ABSTRACT:
A process and apparatus for the manufacture of large glass containers, comprises preparing a glass gob of a predetermined weight in an automatic mechanical feeder and feeding it to a first preparatory mold at a predetermined frequency. A parison is formed in the preparatory mold, at the same frequency, the parison comprising a finished mouth of the glass container to be formed. The parison is then transferred to a second, prefinishing mold, and, at the same frequency, a prefinished parison is formed. The prefinished parison is transferred to a third, finishing mold, and, at a frequency in a ratio of from 1:1 to 1:4 of the predetermined frequency, the finished glass container is formed. The expansion of the prefinished parison is controlled by the action of compressed air conveyed to the interior of the parison from its mouth.
