The cylinder 180 is supported by the frame member 182 which is mounted on top of the cross member 150. This allows the body of the parison to stretch under its own weight and its outer surface to achieve a condition at which the parison can be blown into a final container.
Alternatively, a downward movement of the base plates 108 can be obtained by the motion of the piston and cylinder device 178, 180 to allow the containers to be removed horizontally from final forming station C. The single cycle of the section just described will be understood to provide a method in which the following steps are carried out: (a) supplying a gob of glass to a parison mould at the blank station of the section; (b) forming a downwardly facing parison at the blank station with a finish end portion of the parison in contact with a neck-ring mould of an invert mechanism; (c) inverting the parison held by the neck-ring mould to transfer it to the intermediate station of the section; (d) closing blow mould members about the parison at the intermediate station, performing an initial forming operation on the parison to force it into contact with the interior surface of the blow mould members to provide an initially formed container and releasing the parison from the invert mechanism; (e) moving the blow mould members linearly from the intermediate station to the final forming station and performing a final forming operation to produce a formed container; and.

It will be appreciated that should the sequence described above prove to give an excessive amount of neck-ring contact time for any given container, an alternative sequence could be used in which the neck-ring moulds are opened as soon as the blow moulds are closed leaving the parisons supported by their finishes within the blow mould cavities 15 and the neck-ring mechanism 17 could begin its revert motion before the vacuum and/or blowing air is applied to initially form the containers.

The blow mold with the stabilized parison is then transferred linearly to a final station where the parison is blown into the container. Schwartz, Stephen M. Maschine zum Herstellen von Glaswaren Classification Air under pressure is supplied to the bore 70 on both sides of the piston head 74 through bores (not shown) in the block 2. The air then passes upwardly through cooling passages in the mould members 13 which each have an entrance in a bottom surface of one of the mould members and extend upwardly through the mould members. While this reheating is occurring, the blow moulds at the final forming station C open to release containers formed in the preceding cycle, and the carriage 100 is then moved by the piston and cylinder device 106 to carry the open mould members 13 from the final forming station C to the intermediate station B where the blow mould members are closed around the parisons P. An opening 128 is provided in the frame 110 of the section below the intermediate station B. For example, to manufacture very light containers a parison is required which is, proportionately, shorter than normal in relation to the final container. section. 1997-04-21 classification-ipcr/text, or B511, B512 - See WIPO ST8 for content structure description Standard I.S. 3.
