While, because it avoids an extra downward and upward movement of the blow-head, it is preferred to begin this blowing operation after the neck-ring supports have released the parisons and moved out of the way, it would be possible, if desired, to arrange for the initial blowing to take place through the neck-ring support members, and then to remove the blow-head, move the neck-ring support members out of the way, move the blow-head back into position in contact with the mould members and complete the blowing operation, the blow-head moving with the moulds from the intermediate to the final forming station.

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. After the potentially misloaded glass is cleared and any necessary repairs are made, the machine section may be restarted employing normal restart techniques.

One problem is that of achieving a sufficient cooling of the finish end portion of a parison so that it is sufficiently strong to withstand the further processing steps without distortion. One feature of this machine was that the timing of the mechanisms in the parison forming stage was effectively decoupled from the timing of the mechanisms in the final forming stage, thus allowing the reheat time to be varied without requiring retiming of the mechanisms operating at these two stages.
