Abstract

Each neck tool half is mounted on a neck tool holder and together they are movable from the illustrated initial position in a parison mold station to a finishing mold station. On each neck tool holder is secured a movable part of a distribution device for cooling air. A stationary part of the distribution device transfers cooling air from a stationary supply device having a valve. Between the stationary and movable parts there is a jointing gap which is inclined to the vertical. The cooling air is blown through nozzle apertures against the outside of the neck tool half.
