Abstract
Official abstract text for this publication.
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 ( 15 ) of a drawing tool ( 2 ), said main body supporting at least one profiled drawing roller ( 3 ) which can rotate about a rotation axis ( 5 ) in order to delimit a tool working opening ( 1 ), wherein the drawing roller ( 3 ) lies against the outer surface of the light metal cartridge, the rotation axis ( 5 ) of the drawing roller ( 3 ) is arranged at a tool-internal end area of a lever ( 9 ) arranged transversely relative to the longitudinal axis ( 16 ) of the drawing tool ( 2 ), said lever being supported at its opposite tool-external end area on the drawing tool ( 2 ) so as to be pivotable about a pivot axis ( 11 ) in a force-controlled manner and so as to apply the drawing roller ( 3 ) against the outer surface of the light metal cartridge.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing a connection between the neck area of a light metal cartridge and a plastic container inserted therein, by a drawing process, the method comprising: providing a rotating main body ( 15 ) of a drawing tool ( 2 ), said main body rotating about a centrally located longitudinal axis ( 16 ), the main body supporting at least three profiled drawing rollers ( 3 ) which are each rotatable about respective rotation axes ( 5 ) in order to d…
