Dead plate arrangement

A dead plate arrangement for a glass forming machine, comprising:

• a dead plate which includes a plurality of fields for receiving a plurality of hollow glass articles to be cooled thereon, each of said fields configured for receiving one of said hollow glass articles,
• openings in said fields for the passage of cooling air to said hollow glass articles,
• a cooling air supply for providing cooling air to said openings,
• a plurality of dynamic pressure chambers, each of said plurality of fields being allocated to one of said dynamic pressure chambers, each of said plurality of dynamic pressure chambers being configured to be individually controllable with regard to a cooling air pressure therein,
• a housing attached to the lower side of the dead plate in which the dynamic pressure chambers and a supply air chamber connected to the cooling air supply are arranged, wherein each of said dynamic pressure chambers is connected to the supply air chamber via an air chamber valve which is continuously controllable between an open position and a closed position,
• an overflow channel enabling the cooling air flow to exit via the respective field of the dead plate by bypassing the respective air chamber valve, and a pneumatically actuatable switching mechanism configured for opening and closing the overflow channel.
