Meanwhile the parison hanging in the blow mould is reheating, that is to say the outer, cooler, skin of glass which gives it its shape retaining ability and thus allows it to be transferred without excessive distortion from the blank mould to the blow mould, receives heat from the hotter interior glass and softens. An I.S. The illustrated section is a `double gob` section, that is to say it is adapted to operate on two gobs at a time, and thus comprises two parison moulds 1,3, each comprising two parison mould members 1a, 1b, 3a, 3b which are of conventional construction, being movable between an open and a closed position about a pivot 5. endobj In this machine a stream of molten glass is pushed out of an orifice at the end of the forehearth by a rotating bowl and is subsequently cut to gobs of glass.

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. PATENTED CASE, Owner name: means for opening the blow mould members to allow removal of a finally formed container at the final forming station. 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. 840966 [<>] machine has been specifically developed for production of limited quantities of special glass containers, for training of personnel and for sampling purposes.The machine can be fed by Hand, by Robot and/or by Feeder mechanism. Consequently it proved necessary to begin the blowing operation before the turret began its rotation thus restricting the time available for reheating unless the cycle time was undesirably increased. r200 9 2010-07-10T06:50:57+02:00 No. No. The carriage 100 is arranged to be moved between an intermediate position, in which it is at the intermediate station B, and a final position, in which it is at the final forming station C, by a piston and cylinder device 106.

The carriage 100 is then caused to move by the piston and cylinder device 106 to carry the initially formed containers from the intermediate station B to the final forming station C. While this movement takes place the vacuum applied to the mould cavities is maintained-and thus the initially formed containers are held firmly in the mould cavities and can move without any risk of distortion.
