摘要： PROBLEM TO BE SOLVED: To provide a rotary die cutter which can continuously cut workpieces by appropriately maintaining the pressure of a worn cutting blade and a die roll even if the degree of abrasion of the cutting blade attached to the die roll is different with location. SOLUTION: According to the operation of the rotary die cutter, while pressing surfaces 24a, 24a of the die roll 20 are pressed onto a peripheral surface 32a of an anvil roll 30, the workpiece W is pinched between a cutting edge of the cutting blade 23 and the peripheral surface 32a and then cut by the cutting blade. Although the degree of abrasion of the cutting blade 23 is different by location, a width dimension of the pressing surfaces 24a, 24a facing a portion of the cutting blade, which is worn sooner than the other portion, is shortened, and pressing pieces 25 are fitted to the respective shortened portions. If the pressing pieces 25 are detached when abrasion at the cutting edge is advanced, elastic contractive deformation of the pressing surfaces 24a, 24a is increased, and therefore the pressing force between the worn cutting edge and the peripheral surface 32a is increased.
