Therefore, the present technical solution improves the knife die and sets various devices matched therewith, so that the round knife machine system can cut out the part of the raw material which is not needed for the product A 20 but is needed for the production of the product B 22. After the customized first roller 6 releases the pressure, the part is transferred to the production of the product B 22 by the transfer station, so that the products A and B share one raw material, which effectively reduces the material usage loss and the material cost.
