Abstract (en)
[origin: EP2687383A1] Tool and method for embossing an artifact into a wall of a three-piece can, wherein a flat sheet or blank (s) of metal is transported along a transport bed (10) by several spaced apart groups of rollers (20,22,24), each having a top and a bottom roller. A rotating embossing roller pair (30) is provided between two of the groups of transport rollers, and driven by a servo drive (38). It embosses the artifact (11,11') into the flat, transported sheet or blank. The transport rollers, the embossing rollers and the sheet or blank have the same speed at the surface of the blank during embossing the artifact into the blank or sheet, and a length position of the artifact in the sheet or blank is determined, adjusted or corrected by a speed and position control (40) of the servo drive, driving the embossing roller pair (30) and shaping a cylindrical base shape of the can wall (15).
