The method involves supplying a web or plate-like object (4) i.e. paperboard, to a punching station (1), and punching a set of parallel arranged punching sections (6) using a punching cylinder (2). Another set of parallel arranged punching sections (11) are punched using another punching cylinder (3). The latter set is aligned perpendicular to the former set. The object is punched by the cylinders during a continuous process. The punching sections are provided with protrusions (7, 12) and/or notches (8) aligned perpendicular to the punching sections. An independent claim is also included for a device for manufacturing a punch. |
