Abstract: A method and apparatus for beading the bodies of metal containers, wherein container bodies are rolled between an inner tool and an outer tool, for instance inner and outer rolls, in order to increase their strength. To prevent sliding of the container at the inner and outer tools the container body is coaxially retained with respect to the inner tool. The outer tool is then radially moved, during the beading operation, towards the inner tool, and then the outer tool is rolled upon the inner tool and the intermediately disposed container body.
