ABSTRACT:
A method and an article are disclosed pertaining to the production of book blocks comprising a stack of signatures each having a fold and which together form a spine of the book block, the signatures being aligned with one another on their flat sides and stitched together by means of a binding thread 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, a first one of the at least two spaced transverse seams being formed by chaining together loop-like binding thread sections pulled successively out of the folds of the signature. The chained transverse seam is interrupted after a stack section determining the size of the book block has been formed. A last formed loop-like section of the binding thread is left at an end region of the book block and is unreleasably fastened to at least one of the chained transverse seam and the folds of the signatures.
