Laminating device and method for laminating at least one layer stack

Abstract

The invention relates to a laminating device () and a laminating method for laminating at least one layer stack (), comprising at least one substantially plate-shaped workpiece () and at least one adhesive material layer (), by means of pressure and/or heat. The laminating device comprises a lower part () and an upper part that can be connected to the lower part () in a gas-tight manner. A working chamber () which can be opened and closed and which is for receiving the layer stack () during lamination is formed between the lower part () and the upper part (). A pressure plate () can be moved along a press axis (a-a) in the working chamber () between the upper part () and the lower part (). At least one sealing frame () is arranged between the lower part () and the upper part (). Multiple pressure chambers that can be separated from one another and actuated as required are arranged in the working chamber (), wherein multiple clamping points are provided spaced apart from one another in the direction of the press axis (a-a), wherein at least one flexible element is secured on one of the clamping points for separating a first pressure chamber (), and the moveable pressure plate () can be moved via the application or non-application of pressure or negative pressure to said pressure chamber. Given that the flexible gas-tight element divides the working chamber () into a first pressure chamber () located above the flexible gas-tight element and a second pressure chamber () located below the flexible gas-tight element and in which the moveable pressure plate () is arranged, wherein the movement of the moveable pressure plate () occurs due to a pressure difference between the pressure chambers (), different operating modes of a laminating device can be performed in one unit.
