SLOTTER, CUTTING METHOD OF SLOTTER, SLOTTER KNIFE, AND CUTTER BASE

摘要

In order to avoid scattering of flap chips which causes inferior gluing of a joint margin and intrusion of a flap chip into corrugated sheet products when a joint margin of a corrugated board is formed, a connection is always formed between the flap chip and a slotted chip regardless of the shape of the joint margin. An upper slotter knife (10) is divided into a slotter knife body (12) and a division (14), and the position of the division (14) relative to a sliding member (26) in which a flap cutter knife (30) is embedded is determined and fixed such that a distance (L) between a nick (18) formed on a cutting blade (15) of the division (14) and the tip of a flap cutter knife (30) is minimized. The presence of the nick (18) makes it possible to form a connection (9) between the slotted chip (7) and the flap chip (8) even when the sizes and the shapes of the corrugated sheet (1) and the joint margin (5) vary. The presence of the connecting point (9) makes it possible to remove the flap chip (8) together with the slotted chip (7), so that scattering of the flap chip (8) and inferior gluing of the joint margin can be prevented.
