Title:
METHOD AND DEVICE FOR MAKING GLASS ARTICLES
Document Type and Number:
WIPO Patent Application WO/1993/016007
Kind Code:
A1
Abstract:
The proposed method for making glass articles provides for feeding portions of melted glass and their forming by means of a forming equipment comprising at least one hollow forming element (1) the internal surface of which is covered with the layer (5) of a corrosion-heat-resisting material. In the cavity (4) of the forming element (1) before the feeding of the melted glass is placed a material capable of intensive evaporation at the temperature of forming at a quantity slightly exceeding that needed for filling the cavity (4) of the forming element (1) with the vapours of said material so as to impregnate with it the layer (5) of the corrosion-heat-resisting material after which the forming element (1) is heated up to the temperature of forming, its cavity is evacuated up to Po=(0.02-0.1) Pa and thermoregulation of said material is effected within the interval of the forming temperatures. A device proposed for implementing the method comprises a forming equipment containing at least one forming element (1) with a hermetic cavity (4) in which is placed a material capable of intensive evaporation at the forming temperature in the above-mentioned quantity, the internal surface of the cavity (4) of the forming element (1) is covered with the layer (5) of a corrosion-heat-resisting material, and the cavity (4) itself is connected with a device for its evacuation.
