| 摘要 |
<p>The present invention concerns a method of die-cutting packaging material, wherein the packaging material is brought in between an anvil and at least one cutting knife, wherein the anvil and the cutting knife are moved relative each other during a die-cutting stage so that the cutting knife cuts the packaging material and hit the anvil, and the anvil and the cutting knife withdraw from each other during a subsequent uncovering stage, such that the die-cut packaging material is uncovered from the cutting knife. Further, at least one stopper is fixedly arranged relatively the cutting knife such that the stopper hit the anvil during the die-cutting stage and restrains further relative movement between the cutting knife and the anvil when the cutting knife has completely cut through the packaging material and hit the anvil with a force that only substantially elastically deforms the cutting knife. The present invention also concerns a punch form and a die-cutting machine for use in said method.</p> |
