SYSTEME DE TRANSPORT POUR AMENER AU TROISIEME PLI DES PRODUITS D'IMPRIMERIE PLIES TRANSVERSALEMENT

An arrangement for transferring transversely folded printed products to a third fold has a mechanism for providing a first longitudinal fold, a subsequently arranged mechanism for forming a transverse fold and having an outlet gap, two devices for forming a third fold, located one above the other and each having an inlet gap, two drawing-in roller pairs associated with a respective one of the devices and each having a central axis located in one imaginary vertical plane. The inlet gaps of the devices for forming a third fold and the outlet gap of the mechanism for forming a transverse fold are arranged relative to one another so that an imaginary horizontal plane extending through the outlet gap is simultaneously a plane of symmetry for the inlet gaps. A mechanism for connecting the outlet gap with the inlet gaps and includes a first transporting roller pair, a product deflector and two mirror-symmetrical sheet guides of a same length. The sheet guides have a harmonic course and are each provided with two spaced transporting roller pairs arranged so that a distance between the further transporting roller pairs and a distance between a last one of the further transporting roller pairs and the drawing-in roller pair is smaller than the length of a product to be folded. The further transporting roller pairs and the drawing-in roller pair have speeds which harmonically decrease in a transporting direction.
