A process and an apparatus for preventing a packaging material which is being die-cut and scored from developing cracks. A crack-reducing sheet material (17) is positioned between the cutting/scoring tools (9, 13) and the packaging material (5) to absorb impact energy from said tools and relieve the packaging material of crack-producing forces in the direction of its plane.

Le procédé et l'appareil décrits servent à empêcher un matériau d'emballage qui est découpé à l'emporte-pièce et entaillé de former des craquelures. Un matériau en feuille (17) de réduction des craquelures est disposé entre les outils de découpage/entaillage (9, 13) et le matériau d'emballage (5), de façon à absorber l'énergie d'impact provenant de ces outils et à soulager le matériau d'emballage des forces génératrices de craquelures, qui s'exercent dans la direction de son plan.
