ABSTRACT:
In the manufacture of hollow glass articles such as bottles, a gob of molten glass is blown or pressed into a parison in a premold, the parison being then transferred to a final mold where it is allowed to reside for a period sufficient to equalize its temperature before being blown into its ultimate shape. During the latter step, another final mold receives a parison meanwhile formed in the same premold. The two (or more) final molds associated with a given premold are mounted on a turntable for juxtaposition with the premold preparatorily to each transfer step.
