  • other suitable materials such as corrugated cardboard, plastic films and the like can be processed.
  • a combined scoring and cutting tool is described for example in EP 1 238 793 A1. The tool includes scoring and creasing lines, which are pressed non-positively into slot-shaped recesses of a carrier plate.
  • a disadvantage of the known method for producing such punching, scoring and / or scoring tools is the fact that changes in the layout of the punching and / or scoring and / or scoring tool are very expensive to carry out. If necessary, this significantly increases the cost and delay the production process of the punching and / or scoring and / or scoring tool.
  • Another object of the invention is to provide a carrier plate for a cutting and / or punching and / or scoring tool and a corresponding cutting and / or punching and / or scoring tool, which a quick and economical production even with possible corrections and / or change the design of the cutting and / or punching and / or scoring tool enable.

Furthermore, there is the possibility that the at least one recess is generated with respect to the line with a predetermined oversize and the

The production of the tool can in turn be cost-saving, since with possible corrections of the positioning of the lines no completely new tool produced or a new carrier plate must be used.
