Abstract
An apparatus for producing book blocks from a stack of aligned signatures each having a fold and which together form a spine of a book block. An arrangement for stitching stitches the signatures together with at least two spaced transverse seams formed of a double strand of binding thread passing through each of the folds of the signatures from a location outside of the signatures and extending along an inner edge of each of the folds to an exit point in each of the folds. The transverse seams include a chained transverse seam having loop-like binding thread sections. An interrupting arrangement interrupts the chained transverse seam at an end region of the book block such that a last formed loop-like section of the binding thread remains unchained and is left at the end region of the book block. An unreleasably fastening arrangement unreleasably fastens the last formed loop-like section to either the chained transverse seam and the folds of the signatures.
