The purpose of notching is to enhance the solidification of the bookbinding. The notching blade makes numerous

cuts on the spine of the book so that the melted glue can penetrate the binding area.

Adjustment

In order to get appropriate depth of the cuts and the precision of the center path for clamp station, the notching

station can be adjusted to the up, down, right, and left positions as shown. Note that notching surface should be

adjusted evenly on both sides to prevent tilting the notching surface. Otherwise, the cuts of the book will have one

side deeper than the other. The standard depths of the cuts are 1 mm evenly on the spine of the book.

You also can lift up the notching station to gain the depth of the cuts when the blade has been worn out a little bit.

Or you have to change the blade.
