Abstract
Apparatus for rounding the spines of book blocks comprises rounding elements that act on the sides of the book block, the action of these rounding elements being due to a defined rotation and pressure, the rounding elements consisting of rounding segments which are drive-rotated by actuating mechanisms and can be moved vertically to thereby execute rolling movements on the sides of the book block. The vertical movement of said rounding segments are superimposed on their rotation in a manner such as to compensate for the vertical movement of the book block generated as a consequence of the rotation.
