A bookbinding machine calculates a rotational speed coefficient, which represents the percent change of a rotational speed of a pumprelative to the reference rotational speed of the pump, depending on a thickness of a book block P to be bound and a conveying speed of a clamper by use of a first function defining a relationship between the thickness of the book block and the rotational speed coefficient and a second function defining a relationship between the rotational speed coefficient and the conveying speed of the clamper, calculates the set value of the rotational speed of the pump based on the rotational speed coefficients and the reference rotational speed, and sets the rotational speed of the pump according to the set value of the rotational speed.
