Abstract
An upper slotter knife is divided into a slotter knife body and a division, and the position of the division relative to a sliding member in which a flap cutter knife is embedded is determined and fixed such that a distance between a nick formed on a cutting blade of the division and the tip of a flap cutter knife is minimized. The presence of the nick makes it possible to form a connection between the slotted chip and the flap chip even when the sizes and the shapes of the corrugated sheet and the joint margin vary. The presence of the connecting point makes it possible to remove the flap chip together with the slotted chip, so that scattering of the flap chip and inferior gluing of the joint margin can be prevented.
