Abstract

In a method of producing a connection between the neck area of a light metal cartridge, particularly an aluminium cartridge, and a plastic container inserted therein, by a drawing process that forms a connection area and applies areas of the wall of the light metal cartridge against the plastic container using a rotating main body () of a drawing tool (), said main body supporting at least one profiled drawing roller () which can rotate about a rotation axis () in order to delimit a tool working opening (), wherein the drawing roller () lies against the outer surface of the light metal cartridge, the rotation axis () of the drawing roller () is arranged at a tool-internal end area of a lever () arranged transversely relative to the longitudinal axis () of the drawing tool (), said lever being supported at its opposite tool-external end area on the drawing tool () so as to be pivotable about a pivot axis () in a force-controlled manner and so as to apply the drawing roller () against the outer surface of the light metal cartridge.
