During its production, a rigid corrugated-board web (2) is cut into corrugated-board formats (3) by at least one longitudinal severing cut (41, 42) and transverse severing cuts (51), a continuous movement of the web being maintained in the process. In addition, corner-shaping cuts (61, 62) are punched in coordination with the at least one longitudinal severing cut (41, 42) and the transverse severing cuts (51), these corner-shaping cuts removing corner material in the form of punched parts (63, 64) and producing at least one shaped edge of the corrugated-board formats (3). The corner-shaping cuts (61, 62), which, in relation to the web width, are punched one after the other in at least one width position, the at least one longitudinal severing cut (41, 42) and the transverse severing cuts (51) are made in alignment with one another. A corrugated-board making installation (1) for implementing the method comprises a corner shaping-cut punching arrangement (6), which produces punched sections in the moving corrugated-board web (2) in order to produce the corner-shaping cuts (61, 62), and synchronizing control means (75, 76) for synchronizing the production of the transverse severing cuts (51) with the production of the corner-shaping cuts (61, 62). |
