ABSTRACT:
The movable side portions of a mould of a cyclicly operating glassware forming machine have cooling passages passing upwardly therein from an entrance in a bottom surface of the side portion. A plenum chamber is formed beneath the side portions and has upwardly opening exits which communicate with the entrances of the cooling passages when the side portions are stationary in either an open or a closed position thereof so that cooling air can pass into the cooling passages. In this way, each cooling passage can be supplied with air at substantially the same pressure and low pressure air can be used.
