    • Blow moulding apparatus having a split mould (129) which clamps about one or more tubular thermoplastics parisons (112) which have just been extruded (111) and conveys the parison(s) by a mechanically pivoted movement (131a) to a point beneath a blowing station (115) where pneumatic nozzles (116) engage the top(s) of the parison(s) and inflate them within the mould cavity. As soon as the mouldings are sufficiently chilled to be self-supporting, the mould opens, leaving the mouldings suspended from the blowing nozzles. The return movement of the mould to enclose the next parison(s) brings into position beneath the dangling, cooling mouldings some form of gripping mechanism (126) which is mounted rigidly on the moulds (129) or the lever system on which the moulds move. As soon as the mouldings are set sufficiently to be clamped, the mould closes about the next parison(s) and simultaneously the mouldings are gripped. The mouldings are conveyed to a discharge chute or conveyor as the mould moves back from the extruder to the blowing head with the next set of parisons. Pref. the traversing action or the final removal of the mouldings carries them past automatic deflashing equipment.
