Three-sided book-cutting machine: the positioning requirements of the slitting knife

1. The nicks cut by the nicking knife (also called road knife) must be on the same straight line as the knives on both sides.

2. The slitting knife device must run vertically while working, and must not be skewed, so as to cut the covers at both ends of the book back.

3. The height of the blade plate (blade) must be on a horizontal line with the plane of the machine, and it should not be protruded or recessed.
