Abstract
The invention relates to a method of manufacturing a body for a container, in which a body having a weldseam along its longitudinal direction is formed by bending material in sheet form and welding the overlapping edges of the bended material together, and the wall of the body having the longitudinal weldseam is thinned. Preferably thinning is obtained by wall-ironing. It is advantageous that the wall thickness of a wall part close to wall end of the body is larger than that of a remaining part of the body and eventually prior to thinning has been reduced and that prior to being reduced the body is provided with a gripping rim and/or cover.
