Abstract
1. Method of producing a finished pour opening in a container cover formed from aluminium as a light and gas barrier and from plastics material as protective and sealing layers, having a cutting edge, which is protected from corrosion, along the punched rough opening, characterized in that a) the rough opening (9) is punched-out ; b) a rolled flange (11) is produced along the rough opening (9) in such a manner that the cutting edge (19) abuts, or almost abuts, the root (17) of the rolled flange (11) ; c) the rolled flange (11) is flattened in a calibration station (13), and an accurately defined, calibrated, finished opening (99) is produced ; and d) the rolled flange (11) is thereby flattened until the protective layer (15), which is applied to the cover (1), is displaced from the interior of the rolled flange (11) between the cutting edge (19) and the root (17) in such a manner that the edge (19) is covered with the displaced protective layer (15) and is sealed against corrosion.
