Abstract
The present invention relates to a method for manufacturing a non-axisymmetric tubular metal body (10), intended to form a side wall of a container, preferably a metal can.The method comprises the following steps:- a supplying stage, to supply a cylindrical body (20), with a longitudinal axis (20'),- at least one first radial expansion step, to obtain a tubular preform from said cylindrical body (20),- an angular indexing step, to index said tubular preform about said longitudinal axis, and- at least one second radial expansion step, to obtain said non-axisymmetric tubular metal body (10) from the said tubular preform (30).
