Wird die Gewindespindel 21, von der Seite des Stellmotors 17 her gesehen, nach links gedreht, so wird die Gewindehülse 37 über das Drehrichtungsumkehrgetriebe 44 sowie das Abtriebszahnrad 39 nach rechts gedreht. Bei einem Übersetzungsverhältnis des Getriebes 42, 65, 66, 72, 39 von 1:1 sowie der genannten Steigung des Rechtsgewindes 34 auf der Gewindespindel 21 von 2 mm bewegt sich die Gewindehülse 37 bei einer Umdrehung der Gewindespindel 21 absolut um 4 mm in Richtung Doppelhebel 7. Gleichzeitig bewegt sich jedoch die mit dem Stift 57 in der gehäusefesten Nut gegen Verdrehen gesicherte Anschlaghülse 22 infolge ihres Rechtsgewindes in entgegengesetzter Richtung des Doppelhebels 7. Bei einer genannten Gewindesteigung von 3,5 mm des Gewindes 47 bewegt sich die Anschlaghülse 22 somit um einen Differenzbetrag von 0,5 mm in Richtung Doppelhebel 7.The device according to the invention works like described below. If the threaded spindle 21, of seen the side of the servomotor 17 forth, to the left rotated, the threaded sleeve 37 is on the Direction of rotation reversal gear 44 and the output gear 39 turned to the right. With a gear ratio of the gear 42, 65, 66, 72, 39 of 1: 1 and the mentioned slope of the right-hand thread 34 on the Threaded spindle 21 of 2 mm moves the threaded sleeve 37 absolute with one revolution of the threaded spindle 21 4 mm in the direction of the double lever 7. At the same time it moves however, the one with the pin 57 in the housing-fixed groove stop sleeve 22 secured against rotation as a result their right hand thread in the opposite direction of the Double lever 7. With a thread pitch of 3.5 mm of the thread 47 moves the stop sleeve 22nd thus by a difference of 0.5 mm in the direction Double lever 7.

Da die Gewinde 36; 48 im rechten Getriebe 28 bei gleicher Drehrichtung der Gewindespindel 21 jeweils gegenläufig ausgeführt sind, bewegt sich die rechte Anschlaghülse 23 ebenfalls um einen Differenzbetrag von 0,5 mm in Richtung des Doppelhebels 7 bzw. 8. Somit wird der Walzenspalt 16 vergrößert. Since the thread 36; 48 in the right gear 28 same direction of rotation of the threaded spindle 21 each are executed in opposite directions, the right moves Stop sleeve 23 also by a difference of 0.5 mm in the direction of the double lever 7 or 8 the nip 16 enlarged.

Wird die Gewindespindel 21 vom Stellmotor 17 her gesehen, nach rechts gedreht, so bewegen sich die Anschläge 52; 53 voneinander weg und der Walzenspalt 16 wird verkleinert. Die Druckfeder 14 sorgt für eine spielfreie Einstellung der Anschläge 52; 53. Dabei ist die Druckfeder 14 in ihrer Anstellkraft so bemessen, daß sich der Falzwalzenspalt 16 bei einer Fehleinstellung oder einer Produktstörung selbsttätig auf die Dicke des einlaufenden Produktes einstellt. Somit wird das Falzwalzensystem vor Bruch geschützt.The threaded spindle 21 from the servomotor 17 ago seen, turned to the right, they move Stops 52; 53 away from each other and the nip 16 is reduced. The compression spring 14 ensures a backlash-free adjustment of the stops 52; 53. Here is the compression spring 14 dimensioned so that the folding nip 16 in the event of an incorrect setting or a product fault automatically on the thickness of the incoming product. So it will Fold roller system protected against breakage.

Zwecks einer Nullpunkteinstellung der Walzenspaltmitte können die Anschläge 52; 53 und somit die Enden 12; 13 der Doppelhebel 7; 8 durch Verdrehen der Zahnräder 65; 67 in ihrer Lage verändert werden. Dazu werden die Zahnräder 66; 68 durch Lösen der Schrauben 74; 76 mit der Achse 62; 63 außer Eingriff gebracht.For the purpose of zero point adjustment of the middle of the nip can the stops 52; 53 and thus the ends 12; 13 the double lever 7; 8 by turning the gears 65; 67 be changed in their position. To do this, the Gears 66; 68 by loosening the screws 74; 76 with axis 62; 63 disengaged.

Durch diese Möglichkeit der Feineinstellung des Walzenspaltes 16 kann ein verhältnismäßig grobes Gewinde verwendet werden, dessen Flanken so bemessen sind, daß die im Falzwalzensystem auftretenden Kräfte beschädigungsfrei aufgenommen werden. Die Einstellung des Walzenspaltes 16 kann per Hand geschehen mittels eines anstelle des Stellmotors 17 angeordneten Handrades, wobei statt des Drehsensors 59 eine Skala vorgesehen ist. Die Einstellung des Walzenspaltes 16 erfolgt vorteilhafterweise mittels des Stellmotors 17 z. B. über einen Produktionsrechner im Maschinenleitstand, wobei die Iststellung der Gewindespindel 21 und somit auch die tatsächliche Größe des Walzenspaltes 16 mittels des Drehsensors 59 rückgemeldet wird. Somit ist auch eine hohe Einstellgenauigkeit für einen Wiederholfall gegeben, da pro Umdrehung der Gewindespindel 21 nur eine geringfügige Änderung der Breite des Walzenspaltes 16 erfolgt. Eine selbsttätige Einstellung des Walzenspaltes 16 über den Produktionsrechner kann erfolgen, wenn die Papierdicke und die Seitenanzahl des Falzproduktes in den Produktionsrechner eingegeben werden. Es ist jedoch auch möglich, die Dicke des Falzproduktes mittels einer aus der DE 38 38 314 A1 bekannten Dickenmeßeinrichtung zu ermitteln und dem Produktionsrechner zuzuleiten.This possibility of fine adjustment of the Roll gap 16 can have a relatively coarse thread are used, the flanks of which are dimensioned such that the forces occurring in the folding roller system be recorded without damage. The setting the nip 16 can be done by hand one arranged instead of the servomotor 17 Handwheel, with a scale instead of the rotation sensor 59 is provided. The setting of the nip 16 is advantageously carried out by means of the servomotor 17 e.g. B. on a production computer in Machine control center, the actual position of the Threaded spindle 21 and thus also the actual size of the nip 16 by means of the rotation sensor 59 is reported back. Thus, it is also a high one Adjustment accuracy given for a repeat case, because only one per revolution of the threaded spindle 21 slight change in the width of the nip 16 he follows. An automatic adjustment of the roller gap 16 can be done via the production computer if the Paper thickness and the number of pages of the folded product in the production computer can be entered. However, it is also possible, the thickness of the folded product by means of a Thickness measuring device known from DE 38 38 314 A1 to be determined and sent to the production computer.
