Abstract
A cutting/scoring method for at least one row of adjacent flat elements (3a, 5n) in a material in strip form (1), of which at least one cutting edge (3′-5′) or scoring line, transversely of said strip material (1), is straight and extends from one edge of said strip material (1) to the other, consisting in passing said strip material (1) between cutting/scoring cylinders (R1, R2) of a rotary cutting machine. There is created along said cutting edge (3′-5′) or said scoring line respectively, extending from one edge of said strip material (1) to the other, at least one offset (k, &agr;) in the direction of transit of said strip material (1) so that said cutting edge (3′-5′) or said scoring line respectively does not coincide with the generatrices of said cylinders.
