ABSTRACT:
Apparatus and method are provided for cooling the neck ring (26) and the parison mold (22) of the parison molding portion (20) of an individual section (162) of a glassware molding machine (164) by the use of fan air which is provided to the section box (166) by a motorized fan (300+302) and a fan box (298). The apparatus includes a damper valve (64) with a rotary actuator (82) for selectively controlling flow of fan air to the neck ring (26) and the parison mold (22); and the apparatus includes an isolation sleeve (146) and a temperature controlled valve (170) for utilizing the thermal energy of air discharged from cooling passages (122 and 124) in the parison plunger (116), and for automatically controlling the temperature of the fan air in the section box (166) regardless of ambient air temperatures.
