  • the invention relates to a corrugated cardboard system for producing corrugated cardboard.
  • the invention further relates to a method for producing corrugated cardboard.
  • Corrugated cardboard systems are generally known from the prior art. It is common to stack the corrugated cardboard produced in the form of sheets. The sheets arranged in a stack are generally identical. However, the sheets arranged in the different stacks often differ from one another. It is known from prior public use to manually insert an identification sheet into each stack, which allows simple identification of the respective stack or its assignment to a respective order.
  • the invention has for its object to provide a corrugated cardboard system that is particularly reliable and efficient.
  • a corresponding process for the production of corrugated cardboard is also to be provided.
  • the essence of the invention lies in particular in a cutting arrangement which is capable, on the one hand, of producing (order) sheets according to the order, in particular for further processing, and on the other hand generating at least one identification sheet which is introduced into the respective stack and makes it easy to identify or features.
  • the at least one identification sheet can be produced automatically or independently from the cutting arrangement and can be introduced into the respective stack.
  • the stacks generated can thus be identified on the basis of the at least one identification sheet which is characteristic of this stack, for example by an operator, such as for further transport, carton production or the like.
  • the sheets arranged in a stack are preferably identical with the exception of the at least one identification sheet located therein. They are advantageously arranged one above the other in the respective stack.
