摘要 |
A process for manufacturing a can with a polygonal cross-section and a can with a polygonal cross-section, the process comprising the steps of milling the cylindrical lateral wall of a tubular body (10), providing said wall with a plurality of circumferential ribs (20) which are continuous and axially spaced from each other and defined by a certain degree of radial plastic deformation of the respective circumferential region of the cylindrical lateral wall of the tubular body (10); expanding the formed tubular body (10), deforming it, in order to define longitudinal edges (12) in whose region the circumferential ribs (20) are eliminated; and double-seaming a bottom and an upper wall of the can to the tubular body (10). This process defines a can having any polygonal cross-section and circumferential ribs (20) on the lateral wall thereof, between the longitudinal edges (12). |
