setting the joint
1. In hand binding, the process of positioning the
boards against the shoulders of the text block at
such a distance and in such a manner that the
boards open easily with no strain on the joints
when the leather has dried. Setting the joint is
done following covering but before setting the
headcaps so as not to damage the headcaps by the
opening of the boards. 2. In library and edition
binding, the process of creating the joints of the
book by pressing it between layers of boards
ridged with bands of metal, or by applying
pressure in a casing-in machine, or heat and
pressure in a building-in machine. (276 )
