Station
Function
Holding the book block for the notching, gluing, and nipping processes of bookbinding.
Adjustment
The acceptable spine of a book and the shape of book block after being clamped are shown below. If you
find different shapes such as “round”, “hollow” and “nail head” for one end or both ends, remove the clamp
covers, then adjust the screws on both clamps.

1.) Making book is a top priority (to see where is the machine need to be adjusted ):

book should be good. Because nail head usually happen in thicker books, and round spine usually happen in
thinner books.
