Abstract: The invention relates to a cutting device for the sectioning of a liquid glass strand into individual fragment (gobs) to be further processed into hollow glass articles. In order to achieve a trouble-free cutting process as well as a relatively small mass of the parts moved during the cutting, combined with an increase in the production rate, the invention proposes a cutting device having a housing (2) in which a cutting unit (3) is formed by several partially overlapping cutting elements (4) disposed around the glass strand (5) which are rotatably journaled at one of their ends and connected to the planet gears 7 of a planetary gearing whose outer ring gear (8) is connected with a drive. The cutting edges of the cutting elements (4) are of curved shape.

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.
