It is difficult to restore the positional relationship between the roll and the anvil roll to the state before removal with good reproducibility. For this reason, the cutting edge of the die-cut roll is strongly pressed against the anvil roll to shorten its life, and it takes time and labor to make adjustments to reproduce the positional relationship. Further, if the clearance is small, for example, in the order of several tens of ⁇ m, the housing may hit the support column during assembly and may be rubbed or damaged.
