Aus der DE 38 36 342 A ist eine Vorrichtung zum Längsfalzen eines mindestens einmal gefalzten Druckexemplares mittels eines das Druckexemplar zwischen die Falzwalzen drückenden Falzmessers bekannt. Dabei besitzen die Falzwalzen einen den Falz bildenden ersten Umfangsabschnitt und nachfolgend einen zweiten Umfangsabschnitt mit Aussparungen und Restflächen, wobei die Restflächen das Druckexemplar während des Weitertransportes fixieren, sowie ist dazu anschließend mindestens eine Falzwalze bis auf die für das Transportbandsystem erforderlichen Führungen mit einer in Längsrichtung durchgehenden, das Druckexemplar vollständig von den Falzwalzen freigebenden Aussparung ausgestattet.DE 38 36 342 A is a device for longitudinal folding of at least one Once the printed copy has been folded by means of a print copy between the Folding rollers pressing folding knife known. The folding rollers have a first circumferential section forming the fold and subsequently one second circumferential section with recesses and residual surfaces, the The remaining areas fix the printed copy during further transport, as is then at least one folding roller except for that for the Conveyor belt system required guides with a lengthways direction continuous, completely releasing the printed copy from the folding rollers Recess equipped.
Die vielen zur Achse asymmetrischen Aussparungen der Falzwalzen erschweren deren unwuchtfreie Herstellung, und für die Verarbeitung von Druckexemplaren mit unterschiedlichen Abschnittlängen ist jeweils ein kostenintensives Auswechseln der kompletten Falzwalzen erforderlich.The many recesses of the folding rollers asymmetrical to the axis make it more difficult their unbalanced production, and for the processing of printed copies with different section lengths is always a costly one The complete folding rollers must be replaced.
Der Erfindung liegt die Aufgabe zugrunde, Falzwalzen einer Vorrichtung zum Längsfalzen gemäß dem Oberbegriff von Anspruch 1 zu schaffen, die eine hohe Falzgeschwindigkeit ermöglichend unwuchtfrei und zur Verarbeitung von Druckexemplaren unterschiedlicher Abschnittslänge einfach umrüstbar sind. Diese Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.The invention has for its object to fold a device for To create longitudinal folds according to the preamble of claim 1, which is high Folding speed enables unbalance and for processing Print copies of different section lengths are easily convertible. This object is solved by the characterizing features of claim 1.

einem Grundkörper 11, einem mittig geteilten, radial auf die Achse aufsteckbaren
Zwischenring 12 und zwei den Walzenkörper seitlich begrenzenden Zugringen
13; 14, wovon der zu dem Zwischenring 12 benachbarte Zugring 13 axial
verschiebbar auf der Achse 10 angeordnet ist. Zwischen den Zugringen 13; 14 ist
die mit dem Grundkörper 11 radial verschraubte Falzleiste 4; 5 durchgehend
angeordnet, für die der Grundkörper 11 und der Zwischenring 12 mit einer
achsparallelen Nut 15 (Fig. 4) ausgestattet sind. Des weiteren besitzen der
Grundkörper 11 und die Falzleiste 4, 5 ringförmige, durchgehende Einschnitte 16;
17 zur Führung der Transportbänder 8; 9. Die jeweils über einen Bund 18; 19
(Fig. 4; 5) auf der Achse 10 zentrierten Zugringe 13; 14 und der Zwischenring 12
werden mittels diese jeweils in Durchgangsbohrungen durchsetzender,

Druckexemplares zusammenarbeitenden Randbereich R2 gemäß der
strichpunktierten Darstellung in den Fig. 2 u. 3 das jeweils dritte Umfangsteilstück
des gegenüberliegenden Zugringes 14 und eines zu diesem benachbarten
Abschnittes des Grundkörpers 11 erfassend ausgedehnt werden, um mit
Sicherheit Beschädigungen an beiden Ecken des Druckexemplares
auszuschließen. Andererseits verhindert die lediglich lose Führung des
Druckexemplares außerhalb der Randbereiche R1; R2 eine Faltenbildung in
