<p>In the event that sheet widths are changed as a result of order change, it is made possible to form by machining a slitting slot directed in the widthwise direction of the sheets only at the portions where the slot is necessitated, and thereby breaking of the sheets at the point of change of a specification between the new and old sheets caused by order change, can be prevented. An anvil cylinder (4) is severed along an axial direction of a shaft into a plurality of ring-shaped sections, and elastic bodies (3) are fixedly secured to parts of outer circumferential surfaces of the severed anvil cylinder sections over the entire length of the cylinder. In addition, the respective anvil cylinder sections is adapted to be individually engaged with or disengaged from a knife (1) with the aid of rotary means (12a, 12b). By adjusting the positions of the anvil cylinder sections, slitting slots can be formed by machining only at the portions where slitting slots are necessitated. <IMAGE></p> |
