Abstract (en)
[origin: WO0236327A1] The invention relates to a device (10) for producing a polymer membrane (11), comprising an extruder die (12) for issuing polymer solutions (15, 16), which are supplied to the device (10) via supply channels (13, 14) in the interior of said device and which form the membrane (11), from the outlet opening of the extruder die (12). To produce a multi-layer polymer membrane (11) with integrated layers, the supply channels (13, 14) merge at a certain distance (17) from the outlet opening (122) of the extruder die (12).
