Abstract: The supporting plate arrangement for a glass forming machine, comprises a support plate (4) horizontally held in an engine frame for settling a hollow glass article (1) to be cooled having a supporting surface with openings (9, 9') for delivering cooling air, a cooling air inlet pipe (6), and an electro-pneumatic proportional valve for controlling cooling air flow. A part of the openings located within the supporting surface is arranged for supplying the cooling air and is connected with the cooling air inlet pipe. The supporting plate arrangement for a glass forming machine, comprises a support plate (4) horizontally held in an engine frame for settling a hollow glass article (1) to be cooled having a supporting surface with openings (9, 9') for delivering cooling air, a cooling air inlet pipe (6), and an electro-pneumatic proportional valve for controlling cooling air flow. A part of the openings located within the supporting surface is arranged for supplying the cooling air and is connected with the cooling air inlet pipe. The part of the opening remaining within the supporting surface is arranged for delivering the cooling air. A flat flow guide of the cooling air connected between the openings is arranged to a heat exchanger with a base (2) of the hollow glass article. The openings are arranged with the measure. A large cooling air throughput is representable during the supporting security of the hollow glass article on the supporting surface and limiting a back pressure development. The openings are set in same cross-section. The base of the glass article placed on the support plate forms a peripheral hollow chamber (8) limiting through the supporting surface with the turned surface of the support plate. The openings are connected at the hollow chamber. The openings are distributedly arranged with regard to the representation of a flow field of the cooling air uniformly occupying the base. A connecting groove network, in which the glass article is turned towards the surface of the support plate, formed between the openings is arranged for representing the flow guide of the cooling air coming from the openings for supplying in direction to the openings for delivering. The support surface is surrounded by an arrangement of openings, which are arranged for representing a cooling air flow laterally surrounding the glass article in uniform manner. The cooling air inlet pipe is arranged with regard to a controller of the cooling air flow of all the openings for supplying. The cooling air inlet pipe is arranged with regard to an individual controller of the cooling air flow supplied within and/or outside of the support surface. An intermittent operation of the cooling air flow is controlled by the controller. The openings for supplying the cooling air are connected via individual pipings with the cooling air inlet pipe designed as collecting pipeline. The support surface is arranged to a displacement path for transporting the glass article. The displacement path has a distribution of openings for supplying and delivering the cooling air, which are placed with the measure. The cooling air throughput mediating the heat exchanger is representable nearly at each point along a displacement track during the supporting security of the glass article and limiting the back pressure development.
