ABSTRACT:
The blowhead arrangement comprises a blowhead (18) and a support (10,12,16) therefor. The support defines a passage (50,52,54,56,58,60) through which a first supply of air under pressure can be supplied to the blowhead (18) and a passage (70,74) through which a second supply of air under pressure can be supplied to the blowhead. The first of the supplies of air is used to blow a glass parison in a mould cavity to the shape of the cavity when the blowhead (18) is in position on the glass parison. The second supply is used to cool the finish of the parison by impinging on the finish from openings (90) in the blowhead.
