Laminated glass production at reduced cost

摘要

The invention concerns a method for producing a compound glazing sheet without using an autoclave. The pack consisting of laminated sheets (6, 7, 8) is brought to the softening point of the intermediate plastic film of the sheet pack of in a preheating oven (1). The preheated sheet pack is placed under low pressure in an assembly station under vacuum (2) for extracting the gas from the spaces separating the sheets (6, 7, 8). When the gas has been extracted, the edge of the sheet pack, which is maintained under low pressure, is mechanically compressed inside the container under vacuum and thereby sealed. Finally, the sheet pack is subjected to atmospheric pressure and an additional temperature increase in a post-heating oven (4).
