Abstract: The inventive laminator for laminating structural components, in particular solar module cells or laminated glass panes by combining pressing force and heat, wherein said laminator comprises at least one laminating chamber for receiving one or several structural components, which is provided with a support for said structural components, a heating unit and with a flexible compression membrane which is sealingly stretched in the chamber above the structural element support and is movable with respect thereto. Said membrane separates a lower part of the chamber from a top part thereof, thereby enabling each part to be void of air and aerated. The inventive laminator is characterised in that the copression membrane is embodied in the form of a multiple membrane consisting of a plurality of superimposed membranes.
