ABSTRACT:
A ring type calibrating cage for confining a metal container shell just prior to and during seam welding. The cage comprises a series of strategically located rings through which the can body is fed. These rings are of narrow width reducing friction drag and being optimally positioned to accurately hold the can body in cylindrical shape with overlapped edge portions particularly when these edge portions enter into the welding nip.
