APPARATUS FOR COOLING NECK RINGS IN A GLASS MOLDING MACHINE

摘要

Each neck tool half (6) is mounted on a neck tool holder (8) and together they are movable from the illustrated initial position in a parison mould station (11) to a finishing mould station. On each neck tool holder (8) is secured a movable part (48) of a distribution device (45) for cooling air. A stationary part (47) of the distribution device (45) transfers cooling air from a stationary supply device (27) having a valve (31). Between the parts (47,48) there is a jointing gap (52) which is inclined to the vertical. The cooling air is blown through nozzle apertures (54) against the outside of the neck tool half (6).
