  • Patent number: 10875279
    Abstract: A method for autoclave-free lamination of a composite pane. A stack sequence of a substrate pane, at least one intermediate layer, and a cover pane is produced, a vacuum ring or a vacuum bag is placed around the stack sequence, the stack sequence is deaerated for a period of t?8 min and at a temperature T from 0° C. to 30° C. by application of a negative pressure of p?0.3 bar to the vacuum ring or the vacuum bag, the stack sequence is heated to a temperature T of 70° C. to 115° C., the stack sequence is deaerated for a period t of t?8 min by application of a negative pressure of p?0.3 bar to the vacuum ring or the vacuum bag, the stack sequence is cooled to a temperature T<70° C., the vacuum ring or the vacuum bag is aerated and removed, the stack sequence is heated to a temperature T from 40° C. to 120° C., the stack sequence is pressed together between at least two opposing calender rollers of a first calender unit over the entire width b of the stack sequence.
