Abstract
During manufacture of thread-sewn book blocks (11) from a stack of flat sequentially juxtaposed signatures (3) which are sewn together by way of a double-stranded binding thread (9) which penetrates the folds (4) from the outside and extends in sections along the inside edge of the folds and is pulled out again, the binding thread sections (16, 17) which are inserted by a first sewing needle (5) between the legs (14) of the signatures (3) are captured by a gas jet and conveyed in form of a loop (21) to the adjacent second sewing needle (6) which pulls the loop (21) out of the signature (3) through a return stroke motion using a hook (22).
