Abstract Mould Arrangemnt for glassware forming machine The mould arrangement is for use in a cyclicly operating glassware forming machine. A plenum chamber, forming part of a bottom plate mechanism on which a bottom plate of the mould is carried, extends beneath a mould of the arrangement and has exits through which cooling air may leave the plenum chamber and enter cooling passages in side portions of the mould when the latter are in a closed position thereof. Air is blown into the plenum chamber for a predetermined period in each cycle of operation of the machine and leaves the plenum chamber through the exits thereby cooling the mould by passing through the passages in the side portions thereof. The air leaving the plenum chamber may first pass through passages in the bottom plate of the mould which communicate with the passages in the side portions.
