Abstract
A method of manufacturing a book block with a rounded or a rounded and pressed back includes adhering a first plurality of narrow retaining strips along outer leaves and back of the book block. Additional retaining strips may be applied transversely across the back of the book block in the region of the top and bottom of the back of the book block. Thereafter, the book block may be rounded or rounded and pressed. It is believed that application of the retaining strips prior to the rounding and pressing operations reduces the forces of resistance in the rounding and pressing operations.
