Abstract
A device for the back rounding of book blocks in a book binding machine cooperating with a conveyor device. The device includes a driving arrangement and rounding elements driven in rotation by the driving arrangement. The rounding elements taking up the book block following release of the book block by the conveyor device. The rounding elements acting on both sides of the book block through pressurized rotational movement thereof. When the book blocks are gripped by the rounding elements, the rounding elements may selectively travel in a lifting movement which is separate from the rotational movement into preselectable, defined vertical positions.
