Abstract:
1. Method for laminating a first and a second sheet comprising the steps of: providing a chamber with a first, a second and a third compartment, subsequently arranged along a first axis, a first and a second sheet carrier, and a first and second flexible membrane that extend laterally to a wall of the chamber, wherein the first flexible membrane or the first sheet carrier and the first flexible membrane separate the first and the second compartment of the chamber from each other, and wherein the second sheet carrier and the second flexible membrane separates the second and the third compartment of the chamber from each other, and wherein the sheet carriers are aligned with each other and are arranged transverse to the first axis; applying the first sheet at a side of the first sheet carrier facing the second sheet carrier; applying the second sheet at a side of the second sheet carrier facing the first sheet carrier; maintaining a ratio of a pressure inside the first compartment over a pressure inside the second compartment; detecting a relative position and/or orientation of the second sheet relative to the first sheet; aligning the second sheet relative to the first sheet by moving the second sheet carrier in a direction transverse to the first direction and/or rotating the second sheet carrier around an axis parallel to the first direction; and maintaining a second ratio of the pressure inside the first compartment over the pressure inside the second compartment and a ratio of a pressure inside the third compartment over a pressure inside the second compartment, wherein both the second and third ratios are greater than the first ratio.
