Abstract

The fold rollers have a first circumferential section (U1) forming the fold and comprising a fold strip (4,5) extending along the roller (6,7) and interchangeably connected with same. Tension rings (13,14) seizing the printed copy at the edges adjoin the fold strip. A second circumferential section (U2) fixing the printed copy is formed from a second part of the rings and a second circumferential part of a divided intermediate ring (12). The diameter of the intermediate ring and basic body (11) is slightly reduced opposite the diameter of the tension rings to avoid pressing the printed copy whilst ensuring its guidance for onward transport. The recess (Au) releasing the printed copy is arranged in a first edge area (R1) of the roller comprising part of the intermediate ring and tension ring. The tension ring adjoining the intermediate ring is fixed coaxially displaceable on the roller.

Description

Die Erfindung betrifft die Falzwalzen einer Vorrichtung zum Längsfalzen nach dem Oberbegriff von Anspruch 1.The invention relates to the folding rollers of a device for longitudinal folding the preamble of claim 1.

Aus der DE 38 36 342 C2 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 C2 describes 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 one in the longitudinal 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.

Der für verschiedene Abschnittslängen des Druckexemplares in unterschiedlichen Ausführungen verfügbare geteilte Zwischenring ist in Verbindung mit der axialen Verschiebbarkeit des zu ihm benachbarten Zugringes mit geringem Aufwand problemos radial auf der jeweiligen Falzwalze montierbar. Dabei ist die für hohe Falzgeschwindigkeiten erforderliche Unwuchtfreiheit der Falzwalzen in jedem Fall gegeben, da sowohl die mit der Falzleiste für die kleinste Abschnittslänge bestückte Falzwalze ohne Zwischenring als auch der jeweilige Zwischenring mit dem auf seine Breite entfallenden Abschnitt der Falzleiste für sich getrennt unwuchtfrei sind.The one for different section lengths of the printed copy in different Available split intermediate ring is available in conjunction with the axial Slidability of the adjacent pull ring with little effort Can be easily mounted radially on the respective folding roller. It is for high Folding speeds required freedom from unbalance of the folding rollers in any case given since both the one with the fold bar for the smallest section length equipped folding roller without intermediate ring as well as the respective intermediate ring with the section of the folded strip which is all the way apart are unbalanced.

Auch ist der Fertigungsaufwand für die wenige Aussparungen aufweisenden Falzwalzen relativ gering, zumal hauptsächlich der jeweils mit in der Breite durchgehenden Aussparungen ausgestattete axial aufsteckbare Zugring und Zwischenring getrennt vom übrigen Walzenkörper rationell gefertigt werden können.The manufacturing effort for the few recesses is also Folding rollers relatively small, especially mainly with the width through cutouts equipped with axially attachable pull ring and Intermediate ring can be efficiently manufactured separately from the rest of the roller body can.

The folded printed copy is then between the folding rollers 6; 7 partially wrapping conveyor belts 8; 9 led downwards.

Die in den Fig. 2 u. 3 dargestellte Falzwalze 6; 7 besteht aus einer Achse 10 mit 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, symmetrisch zur Achse 10 angeordneter Schrauben 20 über Gewindebohrungen des Grundkörpers 11 mit diesem verschraubt.The in Fig. 2 u. 3 shown folding roller 6; 7 consists of an axis 10 with a base body 11, a centrally divided, radially attachable to the axis Intermediate ring 12 and two pull rings laterally delimiting the roller body 13; 14, of which the pull ring 13 adjacent to the intermediate ring 12 is axial is slidably disposed on the axis 10. Between the pull rings 13; 14 is the fold bar 4 radially screwed to the base body 11; 5 continuously arranged for which the base body 11 and the intermediate ring 12 with a axially parallel groove 15 (Fig. 4) are equipped. Furthermore, the Basic body 11 and the fold bar 4, 5 annular, continuous incisions 16; 17 for guiding the conveyor belts 8; 9. Each with a federal government 18; 19th (Fig. 4; 5) on the axis 10 centered pull rings 13; 14 and the intermediate ring 12 become more penetrating in through holes, Screws 20 arranged symmetrically to the axis 10 via threaded holes of the base body 11 screwed to it.

Die Falzwalze 6; 7 besitzt einen den Falz des Druckexemplares bildenden ersten Umfangsabschnitt U1, der aus der Falzleiste 4; 5 und jeweils einem das Druckexemplar am Rand erfassenden ersten Umfangsteilstück der Zugringe 13; 14 besteht.The folding roller 6; 7 has a first circumferential section U 1 which forms the fold of the printed copy and which is formed from the fold bar 4; 5 and in each case a first peripheral section of the pull rings 13; 14 exists.

Daran schließt sich ein das Druckexemplar nach dem Falzen während des Weitertransportes fixierender zweiter Umfangsabschnitt U2 der Falzwalze 6; 7 an, der aus dem jeweils zweiten Umfangsteilstück der Zugringe 13; 14 und jeweils einem dazu achsparallelen, an die Falzleiste 4; 5 sich in Umfangsrichtung jeweils anschließenden zweiten Umfangsteilstück des Zwischenringes 12 und des Grundkörpers 11 besteht, wobei der Durchmesser des Zwischenringes 12 und des Grundkörpers 11 gegenüber dem Durchmesser der Zugringe 13; 14 zum einen eine Pressung und damit eine Faltenbildung des Druckexemplares vermeidend und zum anderen jedoch dessen Führung während des Weitertransportes gewährleistend um den Bruchteil eines Millimeters - beispielsweise 0,2 mm - geringfügig reduziert ist.This is followed by a second circumferential section U 2 of the folding roller 6 which fixes the printed copy after folding during further transport; 7, which consists of the respective second peripheral section of the pull rings 13; 14 and one each axially parallel to the fold bar 4; 5 there is a second circumferential section of the intermediate ring 12 and the base body 11, which is adjacent in the circumferential direction, the diameter of the intermediate ring 12 and the base body 11 compared to the diameter of the pull rings 13; 14 on the one hand avoiding pressing and thus wrinkling of the printed copy and on the other hand ensuring its guiding during further transport is slightly reduced by a fraction of a millimeter - for example 0.2 mm.

Schließlich ist zumindest eine Falzwalze mindestens in dem mit der offenen Seite des Druckexemplares zusammenarbeitenden Randbereich R1 mit einer das Druckexemplar vollständig von den Falzwalzen 6; 7 freigebenden Aussparung Au ausgestattet, die sich in jedem Fall jeweils aus einem dritten Umfangsteilstück des Zwischenringes 12 und des zu diesem benachbarten Zugringes 13 zusammensetzt. Dadurch werden Beschädigungen des Druckexemplares infolge des

Whip effect "avoided at the particularly vulnerable corner of the open side of the printed copy.

Die Aussparung Au kann jedoch auch auf den mit der geschlossenen Seite des 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 diesem Bereich.The cutout Au can, however, also on the edge area R 2 cooperating with the closed side of the printed copy, as shown in dash-dotted lines in FIGS. 3, the third circumferential section of the opposite pull ring 14 and a section of the base body 11 adjacent to it are extended in order to exclude damage to both corners of the printed copy with certainty. On the other hand, the only loose guidance of the printed copy outside the edge areas R 1 ; R 2 wrinkling in this area.

Die Falzwalzen 6; 7 gestatten ohne deren Montage eine Verarbeitung von Druckexemplaren unterschiedlicher Abschnittslängen Al. Dazu sind der Zwischenring 12 und die Falzleiste 4; 5 in unterschiedlichen Ausführungen mit der der jeweiligen Abschnittslänge Al entsprechenden Breite B bzw. Länge L austauschbar. Um die für eine hohe Falzgeschwindigkeit erforderliche Unwuchtfreiheit der Falzwalze 6; 7 zu gewährleisten, ist diese mit einer beiderseitig mit dem Grundkörper 11 abschließenden Falzleiste 4; 5 für die kleinste Abschnittslänge Al des Druckexemplares sowie den Zugringen 13; 14, jedoch ohne den Zwischenring 12 ausgestattet sowie der jeweilige Zwischenring 12 mit dem auf seine Breite B bezogenen Anteil der Falzleiste 4; 5 für sich getrennt unwuchtfrei.The folding rollers 6; 7 allow processing of Printed copies of different section lengths Al. For this are the Intermediate ring 12 and the fold bar 4; 5 in different versions with the Width B or length L corresponding to the respective section length Al interchangeable. In order to achieve the high folding speed Unbalance of the folding roller 6; 7 to ensure this is with a folding strip 4, which closes on both sides with the base body 11; 5 for the smallest section length Al of the printed copy and the pull rings 13; 14, but without the intermediate ring 12 and the respective intermediate ring 12 with the proportion of the folding strip 4 based on its width B; 5 for yourself separately unbalanced.

Zum Massenausgleich für die Aussparung Au ist der Zwischenring 12 aus Aluminium mit einer relativ geringen Dichte gefertigt und besitzt dieser benachbart zur Aussparung Au Hohlräume 21, die mit einer Auswuchtmasse 22 aus Stahl mit einer relativ hohen Dichte ausgefüllt sind. Zusätzlich besitzt der Zwischenring 12 in seiner der Aussparung Au gegenüberliegenden Hälfte mehrere die Masse reduzierende Hohlräume 23 (Fig. 4). Mit letztgenannten Hohlräumen 24 ist auch der jeweils ausgesparte Zugring 13; 14 ausgestattet (Fig. 5).The intermediate ring 12 is made for mass compensation for the recess Au Made of aluminum with a relatively low density and has this adjacent to recess Au cavities 21, which with a balancing mass 22 made of steel are filled with a relatively high density. In addition, the intermediate ring 12 in its half opposite the cutout Au several the mass reducing cavities 23 (Fig. 4). With the latter cavities 24 too the respective recessed pull ring 13; 14 equipped (Fig. 5).

Zur Erhöhung der Verschleißfestigkeit ist es günstig, die Falzwalze 6; 7, insbesondere jedoch den Zwischenring 12, mit einer Keramikschicht auszustatten.To increase the wear resistance, it is advantageous to fold roller 6; 7, in particular, however, to equip the intermediate ring 12 with a ceramic layer.
