METHOD FOR CUTTING, CREASING AND/ OR EMBOSSING A CARDBOARD AND CARDBOARD PROCESSING MACHINE
20250050613 · 2025-02-13 · ·

A method is provided for cutting, creasing and/or embossing a cardboard in a cardboard processing machine (10) comprising a rotary die cutting machine (12), the rotary die cutting machine (12) comprising a first rotating cylinder (22) and a second rotating cylinder (24), wherein each of the first and the second cylinder (22, 24) has a cutting, creasing and/or embossing area (26) and a compensation area (28) that extends along the circumference of the respective cylinder (22, 24). A continuous cardboard web (11) being printed with a plurality of repetitive printed sections (40, 41, 42) is run between the two cylinders (22, 24) in a processing direction, wherein a printing length (l) of a printed section (40, 41, 42) is shorter than a circumference of the rotating cylinders (22, 24). Afterwards the cardboard web (11) is pulled back in a direction opposite to the processing direction to such an extent that after a full rotation of the rotating cylinders (22, 24) the cutting, creasing and/or embossing area of the rotating cylinders (22, 24) meets the beginning of the second printed section (41). Moreover, a cardboard processing machine (10) is provided.

A process for providing indicia and an elastic-like behavior to a web substrate is disclosed. The process comprises the steps of: providing a web substrate; printing indicia on the web substrate; and, providing the web substrate with a plurality of first regions and a plurality of second regions comprising the same material composition. A portion of the first regions extend in a first direction while the remainder of the first regions extend in a second direction perpendicular to the first direction to intersect one another. The first regions form a boundary completely surrounding the second regions. The second regions comprise a plurality of raised rib-like elements. The first regions undergo a molecular level and geometric deformation and the second regions initially undergo a substantially geometric deformation when the web material is subjected to an applied elongation along at least one axis.
