Ein Falzklappenzylinder 1 weist in bekannter Weise an seinem Umfang verteilt, mehrere Falzklappensysteme auf. Jedes Falzklappensystem besteht aus einer ersten Reihe auf einem Träger aufgereihter und in bekannter Weise schwenkbarer Falzklappenelemente 4, die mit einer zweiten Reihe zylinderfester Gegenfalzklappenelemente 3 zusammenwirken. Es können auch beide Reihen von Falzklappenelementen 3, 4 schwenkbar angeordnet sein. Prinzipiell besteht jedes Falzklappenelement 4 bzw. jedes Gegenfalzklappenelement 3 aus einer Befestigungsplatte 5, 10 und einem Falzwerkzeugträger 15, 20. Die Befestigungsplatte 10, 5 jedes Falzklappenelementes 4 bzw. jeden Gegenfalzklappenelementes 3 ist auf einem schwenkbar gelagerten bzw. auf einem zylinderfesten Träger, z. B. mittels Schrauben befestigt.A folding jaw cylinder 1 instructs in a known manner distributed over its circumference, several jaw systems. Each jaw system consists of a first row lined up on a support and in a known manner pivotable jaw elements 4, with a second row of cylinder-fixed counter-fold flap elements 3 work together. You can also use both rows of Folding jaw elements 3, 4 can be arranged pivotably. In principle, each jaw element 4 or each counterfold flap element 3 from one Fastening plate 5, 10 and a folding tool carrier 15, 20. The mounting plate 10, 5 each Folding element 4 or each Counter-fold flap element 3 is pivotable on one stored or on a cylinder-fixed carrier, for. B. attached by screws.

Jeder Falzwerkzeugträger 15, 20 weist eine abgeschrägte Falzfläche 11, 12 bzw. 13, 14 auf. Zumindest eine Falzfläche 11 oder 12 bzw. 13 oder 14 ist davon profiliert. Sind zwei FaLzflächen 11, 12 bzw. 13, 14 profiliert, so sind beide Falzflächen 11, 12 bzw. 13, 14 bei geschlossenem Falzmaul kammartig miteinander in Eingriff bringbar.Each folding tool carrier 15, 20 has a bevelled one Folding surface 11, 12 or 13, 14. At least one Folding surface 11 or 12 or 13 or 14 is of it profiled. Are two fold surfaces 11, 12 and 13, 14 profiled, so both rebate surfaces 11, 12 and 13, 14th with the jaws closed, like a comb Intervention can be brought.

Nach dem ersten Ausführungsbeispiel tragen beide Falzflächen 11, 12 z. B. hochliegende Teile 16, 18 mit rechteckförmigem Querschnitt (Fig. 2), die sich von einer äußeren Haltekante 21, 22 über die Falzfläche 11, 12 mit einer Länge L, z. B. 4 mm hin zu einer inneren Falzkanten 23, 24 erstrecken. Die hochliegenden Teile 16, 18 weisen jeweils eine Breite e auf und sind jeweils durch niedrigliegende Teile 17, 19 mit einer Breite d getrennt bzw. benachbart. Dabei ist d > e, z. B. 7 mm > 5 mm. Die hochliegenden Teile 16 des Gegenfalzklappenelementes 3 sind bei geschlossenem Falzmaul 8 mit den niedrigliegenden Teilen 19 des Falzklappenelementes 4 kämmend in Eingriff. Ebenso sind die niedrigliegenden Teile 17 des Gegenfalzklappenelementes 3 mit den hochliegenden Teilen 18 des Falzklappenelementes 4 kämmend in Eingriff, so daß eine Signatur 7 nach einem Querfalzen mittels eines Falzmessers 6 zu einem Falzprodukt 9 auch noch kurze Längsprägungen 26 erhält (Fig. 8). Die Längsprägungen 26 verlaufen nicht parallel zur Falzkante 23, 24, der sogenannten Querfalzkante.According to the first embodiment, both wear Folded surfaces 11, 12 z. B. high parts 16, 18 with rectangular cross-section (Fig. 2), which differs from an outer retaining edge 21, 22 over the fold surface 11, 12 with a length L, z. B. 4 mm towards an inner Fold edges 23, 24 extend. The high parts 16, 18 each have a width e and are each by low lying parts 17, 19 with a width d separated or adjacent. Here, d> e, e.g. B. 7 mm> 5 mm. The high parts 16 of the Counterfold flap element 3 are closed Folding jaw 8 with the low lying parts 19 of the Folding element 4 intermeshing. Likewise are the low lying parts 17 of the Counter-fold flap element 3 with the high parts 18 of the jaw element 4 intermeshing, so that a signature 7 after a cross folding by means of a Folding knife 6 to a folded product 9 also short Longitudinal embossments 26 receives (Fig. 8). The longitudinal embossments 26 do not run parallel to the folded edge 23, 24, the so-called cross fold edge.

Die hochliegenden Teile 16, 18 bzw. die niedrigliegenden Teile 17, 19 verlaufen von der äußeren Haltekante 21, 22 in einem Winkel Alpha < 180°, z. B. von 10° bis 170°, vorzugsweise jedoch in einem Winkel Alpha von 90°, zur Falzkante 23, 24 der Falzfläche 11, 12 (Fig. 1 bis 3). Somit erhält das Falzprodukt 9 Prägungen 26, die vorzugsweise in der Transportrichtung G des Falzproduktes 9 bzw. in Bewegungsrichtung F des Falzmessers 6 verlaufen. Die Prägungen 26 sind im Querschnitt rechteckförmig ausgebildet, so daß das Widerstandsmoment des Falzproduktes 26 in seiner Transportrichtung G erhöht ist. Die niedrigliegenden Teile 17, 19 weisen gegenüber den hochliegenden Teilen 16, 18 über die gesamte Länge l der Falzfläche 11, 12 den gleichen Niveauunterschied auf.The high parts 16, 18 and the low parts Parts 17, 19 extend from the outer retaining edge 21, 22 at an angle alpha <180 °, e.g. B. from 10 ° to 170 °, but preferably at an angle alpha of 90 ° to Folding edge 23, 24 of the folding surface 11, 12 (Fig. 1 to 3). The folded product thus receives 9 embossings 26 which preferably in the transport direction G of the Folded product 9 or in the direction of movement F of Folding knife 6 run. The embossments 26 are in the Cross section rectangular, so that Section modulus of the folded product 26 in its Direction of transport G is increased. The low lying Parts 17, 19 face the high parts 16, 18 over the entire length l of the fold surface 11, 12 the same level difference.

Nach einer weiteren Ausbildung der Erfindung verlaufen die hochliegenden 16, 18 bezüglich den niedrigliegenden Teilen 17, 18 von der äußeren Haltekante 21, 22 zur inneren Falzkante 23, 24 der Falzfläche 11, 12 jeweils in einem Winkel Beta, z. B. von 4° (Fig. 1 und 3). Somit sind die hochliegenden Teile 16, 18 von der äußeren Haltekante 21, 22 zur inneren Falzkante 23, 24 der Falzfläche 11, 12 hin zunehmend keilförmig ausgebildet, d. h. die Oberfläche der Falzfläche 11, 12 vergrößert sich in der genannten Richtung ständig.After a further development of the invention the high 16, 18 with respect to the low Parts 17, 18 from the outer retaining edge 21, 22 to inner fold edge 23, 24 of the fold surface 11, 12 each at an angle beta, e.g. B. of 4 ° (Fig. 1 and 3). Consequently are the high parts 16, 18 from the outer Holding edge 21, 22 to the inner folded edge 23, 24 of the Fold surface 11, 12 increasingly wedge-shaped, d. H. the surface of the fold surface 11, 12 enlarged yourself in that direction constantly.

Nach dem zweiten Ausführungsbeispiel trägt jedes schwenkbare Falzklappenelement 4 auf seiner Falzfläche 14 herausstehende Teile 27 mit jeweils einem dreieckigen Querschnitt. Jedes zylinderfeste Gegenfalzklappenelement 3 weist auf seiner Falzfläche 13 Nuten 28 auf, die bei geschlossenem Falzmaul 8, d. h. Abstand der Falzflächen 13, 14 gleich Null, formschlüssig miteinander in Eingriff bringbar sind.According to the second embodiment, everyone wears pivotable jaw element 4 on its fold surface 14 protruding parts 27, each with a triangular Cross-section. Every cylinder-fixed counterfold flap element 3 has 13 grooves 28 on its fold surface, which at closed jaw 8, d. H. Distance of the folding surfaces 13, 14 equal to zero, form-fitting with each other in Intervention can be brought.

Die Nuten 28 können durchgehend, d. h. über die gesamte Länge l mit einer Breite h ausgebildet sein. Das gleiche gilt dann für die herausstehenden Teile 27, die mit den Nuten 28 bei geschlossenem Falzmaul 8 formschlüssig in Eingriff sind.The grooves 28 can be continuous, i. H. over the whole Length l be formed with a width h. The same then applies to the protruding parts 27 with the Grooves 28 with a closed jaw 8 in a form-fitting manner Are intervention.

Diese herausstehenden Teile 27 bzw. Nuten 28 verlaufen von der äußeren Haltekante 21, 22 in einem Winkel Alpha < 180°, z. B. von 10° bis 170°, vorzugsweise jedoch in einem Winkel Alpha von 90° zur inneren Falzkante 23, 24 der Falzfläche 13, 14.These protruding parts 27 or grooves 28 run from the outer retaining edge 21, 22 at an angle Alpha <180 °, e.g. B. from 10 ° to 170 °, preferably however at an angle alpha of 90 ° to the inner Folding edge 23, 24 of the folding surface 13, 14.

Dabei haben die herausstehenden Teile 27 bzw. die Nuten 28 an der äußeren Haltekante 21, 22 noch einen Abstand h, z. B. von 12 mm voneinander, während sie sich am Ende der Falzfläche 13, 14, an der Falzkante 23, 24, einander berühren. Somit vergrößert sich die Oberfläche der Falzfläche 13, 14 in der genannten Richtung ständig. Ein Steigungswinkel Beta, z. B. von 4° besteht zwischen einem herausstehenden Teil 27 und dem Grund der Nut 28 (nicht dargestellt).The protruding parts 27 and the grooves 28 on the outer retaining edge 21, 22 still a distance h, e.g. B. of 12 mm from each other while they end up the fold surface 13, 14, at the fold edge 23, 24, each other touch. This increases the surface area of the Folding surface 13, 14 constantly in the direction mentioned. On Pitch angle beta, e.g. B. of 4 ° exists between a protruding part 27 and the bottom of the groove 28 (not shown).

Zusammenfassend besteht das erfindungsgemäße Verfahren darin, daß eine in das Falzmaul 8 eines Falzklappensystems durch das Falzmesser 6 eingebrachte Signatur 7 quergefalzt wird und dabei wellenartige Prägungen 26 erhält. Durch die Prägungen 26 ist der Papierfaserverbund zumindest teilweise gedehnt. Es wird eine bleibende Verformung, d. h. eine Prägung erzielt. Die Prägungen 26 erstrecken sich jeweils in einer Länge L, vorzugsweise in der Bewegungsrichtung F des Falzmessers 6.In summary, the method according to the invention exists in that one in the folding jaw 8 one Folding system brought in by the folding knife 6 Signature 7 is crimped and is wavy Embossing 26 receives. Through the embossments 26 is the Paper fiber composite at least partially stretched. It will a permanent set, d. H. achieved an embossing. The embossments 26 each extend in one length L, preferably in the direction of movement F of Folding knife 6.

Ein so in unmittelbarer Nähe der äußeren Querfalzkante 2 ausgestaltetes Falzprodukt 9 weist in Transportrichtung G des Falzproduktes 9 ein erhöhtes Widerstandsmoment auf.So in the immediate vicinity of the outer transverse fold edge 2 configured folding product 9 points in the transport direction G of the folded product 9 an increased section modulus on.

Durch die Prägung erhalten also alle aufeinanderliegenden Blätter des Falzproduktes 9 eine bleibende Verformung, ohne daß die einzelnen Blätter miteinander irgendwie verbunden werden, wie es bei einer Haftriffelung geschehen würde. So through the embossing everyone gets sheets of the folded product 9 one on top of the other permanent deformation without the individual leaves somehow connected to each other, like in a Detention would happen.
