| 摘要 |
The invention concerns a punch form for die-cutting of packaging material (5), comprising cutting knives (2) and/or scoring rules, the punch form (1) is at least partly dressed with sheet material (4) which is arranged in the punch form (1) so that crack reducing of the packaging material (5) is achieved at lease in connection to the cutting knives (2) and/or scoring rules. The friction and the adhesion between the sheet material (4) and the packaging material (5) is so low that a relative sliding can occur between the sheet material (4) and the packaging material (5) during the die-cutting course, which includes a combined ejecting and cleaning course. |
