Abstract
A glassware forming system includes a forming mould and cooling means for removing heat from the forming mould. The cooling means comprises a cooling chamber which is spaced from an external surface of the forming mould by a cavity which contain fluidizable material. Means is provided for circulating a cooling fluid, such as water, through the cooling chamber. The cooling means further includes means for forming a fluidized bed from the fluidizable material within the cavity whereby heat may be transferred from the mould to the cooling fluid when a fluidized bed is formed in the cavity. The rate of transfer of heat from the external surface of the forming mould may be varied by controlling the rate of supply of gas to the cavity and thereby varying the degree of fluidization of the fluidized bed, by varying the rate of flow of cooling fluid through the cooling chamber, or by varying the temperature of the cooling fluid which is passed into the cooling chamber.
