Abstract
A device is provided to shape a spine of a book casing positioned horizontally spread out flat and oriented to be distributed evenly over a spine of a book block. Two fold-shaping rails are arranged extending in a direction parallel to one another. A movable, shaping tool is arranged to face the inside of the book casing spine to shape a web on the book casing spine with the aid of the two fold-shaping rails. The shaping tool includes two spaced-apart support bars that extend parallel to the fold-shaping rails and are arranged to be adjustable so that together they adjust the web width of the book casing spine in a direction transverse to the direction of extension of the fold-shaping rails.
