Abstract (en)

[origin: EP0799718A1] A roughening tool (4) rotates around a rotary axis, which has machining surfaces penetrating the book block spine. The machining edges (9) rotate in a cutting plane and are arranged on the face side of the periphery of the roughening tool (4). The machining edges and the machining plane on the book block spine form a flat adjustment angle ( alpha ). The markings opposite each other, produced by the roughening tool extending laterally over the book block spine, have different machining depths. The un-roughened spine section and the rotary axis of the roughening tool form an angle of more than 90 degrees.
