Abstract: PROBLEM TO BE SOLVED: To provide a method for assembling two parallel plates containing a closed internal space in a furnace kept at the vacuum state or in the neutral atmosphere, optimizing the removal of the gas discharged in a screen, and suitable for batch processing. SOLUTION: In the first stage, a first seal 5 melted at the first temperature T1 is used to seal the periphery, and an opening is maintained by at least one of openings 13, 13' communicated with an internal space. The opening is closed by a closing part 14 having the insertion of a second seal 15 melted at the second temperature T2 lower than the first temperature T1.

Abstract: The vacuum assembly method in an oven assembles two parallel screens (1,4) in an internal space (6). The peripheral sealing is effected in two steps. In the first step, a first sealing joint (5) is sealed, maintaining open a second hole (13) of communication with the internal space. In a second step, a closure element (16) seals a second sealing unit (15) sealed at a second temperature lower than the first sealing temperature.
