ABSTRACT:
A device for laminating two different foils in vacuo with the aid of an electrical gas discharge has two separate treatment chambers or areas, in which different vacuo can be set, so that the treatment can be adjusted in accordance with the corresponding foil, i.e. it can be performed in an optimum manner in accordance with the physical and chemical characteristics of the foil. The electrical gas discharge is a plasma discharge, i.e. a low energy gas discharge in vacuo. Advantageously, the electrodes can be operated at different power levels in the individual, separate treatment areas. For adapting the atmosphere in the treatment areas to the foil characteristics, it is also possible to introduce different gases and optionally carry out an additional heat treatment.
