Abstract
We are aiming to make the die cutter stable for a long time. Wear conditions change with different combinations of materials for die cutters and anvil rolls. We required an anvil roll with prolonged
operational lifetime and reduced cutting-edge chipping risk. In a previous study, we evaluated a carbide coated (CC) anvil roll through comparative testing with other materials. In the present study, we conducted long-run tests under high load conditions. We report the wear on the anvil roll and cutting edge of the die cutter, in relation to Young's modulus and hardness. Our results show that neither chipping nor a rapid increase in the cutting edge land width were observed for the CC anvil roll. In addition, the CC anvil roll prolongs operational lifetime and reduces the risk of cutting-edge chipping under high-load conditions.
