A process and apparatus for the production of a book block, including sheet feeders disposed in series alongside a continuously running, transversely inclined conveyor belt, so that the sheets are successively fed from the feeders and successively disposed one upon the other on the conveyor belt to form a packet. Each sheet is first conveyed from its associated feeder at a downwardly inclined angle, and in a transverse direction with respect to the conveyor belt, and thereafter accelerated at another downwardly inclined angle and in the direction of the conveyor belt to obtain the conveyor belt speed for deposit thereon. From the conveyor belt, the packets are perforated, aligned, cut into strips and again aligned, all of which being performed at the same inclined angle as the conveyor belt. The strips are then folded and cut into quires. The quires are scaled off and then thrust together and thereupon gathered into the book block blank. Fold bands convey the folded strips in an upright standing position into conveyor belts which are disposed in a fan-like arrangement in order to feed the folded strips into the quire cutting station. The stations positioned after the conveyor belt are disposed in a horizontal arrangement to provide for alignment of the packets and the strips.
