The outgassing during the process does not affect the life of the device. Since the forces are not introduced punctually via hydraulic / pneumatic cylinder, an approximately isobaric pressing behavior is achieved. Furthermore, the edge pressure that is detrimental to the manufacturing process is reduced since a substantially uniform lowering and pressing operation is achieved over the entire surface of the press plate. The manufactured products therefore have better quality. Furthermore, the device has a lower weight than comparable hydraulic presses.

Abstract

L'invention concerne un procédé et un dispositif de pressage d'éléments en forme de plaque, en particulier de modules photovoltaïques. Le procédé est mis en œuvre dans un espace de travail sans membrane de compression, en utilisant une plaque de pression munie d'un joint d'étanchéité périphérique gonflable. La plaque de pression est pressée contre l'élément à presser par la production d'un vide dans l'espace de travail, la pression dans le joint d'étanchéité gonflable étant simultanément ou précédemment réduite pour réaliser une compression isobare plane uniforme de la plaque de pression contre l'élément à presser. On peut ainsi mettre en œuvre un procédé économique qui permet une opération de pressage particulièrement uniforme.
