Abstract (en)
[origin: US4839491A] An improved method of forming a cylindrical metal can body is disclosed. The improvement includes forming special ears for the bale and orienting the ears in a specific direction so that the ears can be resistance welded to flat rectilinear sheet stock which can subsequently be accurately rolled into a cylindrical form with a closely controlled overlap.
