Lamination device and process thereof

The invention relates to a lamination device (1) for laminating a photovoltaic stack (32) on a profiled metallic panel (28), the lamination device comprising a lid (3) covered on its underside with an upper flexible pressure membrane (20) so as to form an airtight upper chamber (10) that may be ventilated or evacuated and/or comprising an upper heating device (11) whose bottom side has a crenellated profile, the device also comprising a chassis (2) covered on its top with a lower flexible pressure membrane (6) so as to form an airtight lower chamber (7) that may be ventilated or evacuated and/or comprising a lower heating device (23) whose upper side has a cross-section which differs from the crenellated profile of the bottom side of the upper heating device, wherein the lid is capable of sealably laying on the chassis so that the cavity thus formed is airtight and may be ventilated or evacuated. The invention also relates to the corresponding process.
