Abstract

Falzwalzen (6,7) einer Vorrichtung zum Längsfalzen eines mindestens einmal gefalzten Druckexemplares

  • mit einem den Falz bildenden ersten Umfangsabschnitt (U1) der Falzwalzen (6,7)
  • mit einem das Druckexemplar nach dem Falzen während des Weitertransportes fixierenden zweiten Umfangsabschnitt (U2) der Falzwalzen (6,7),
  • mit einem mit mindestens einer das Druckexemplar vollständig von den Falzwalzen (6,7) freigebenden Aussparung (Au) ausgestatteten dritten Umfangsabschnitt mindestens einer Falzwalze (6,7).
Folding rollers (6, 7) of a device for longitudinally folding a printed copy folded at least once
  • with a first peripheral section (U 1 ) of the folding rollers (6, 7) forming the fold
  • with a second circumferential section (U 2 ) of the folding rollers (6, 7) that fixes the printed copy after folding during further transport,
  • with a third circumferential section equipped with at least one recess (Au) which completely clears the printed copy of the folding rollers (6,7) and has at least one folding roller (6,7).

Um Falzwalzen zu schaffen, die eine hohe Falzgeschwindigkeit ermöglichend unwuchtfrei und zur Verarbeitung von Druckexemplaren unterschiedlicher Abschnittslänge einfach umrüstbar sind,

  • besteht der erste Umfangsabschnitt (U1) aus einer in unterschiedlichen, abschnittslängenvariablen Ausführungen austauschbaren Falzleiste (4;5) sowie jeweils einem zu dieser achsparallelen Umfangsteilstück zweier seitlich an die Falzleiste (4;5) angrenzender Zugringe (13;14),
  • besteht der zweite Umfangsabschnitt (U2) jeweils aus einem zweiten Umfangsteilstück der Zugringe (13;14) und einem dazu achsparallelen, an die in eine Nut eingelassenen Falzleiste (4;5) sich in Umfangsrichtung anschließenden zweiten Umfangsteilstück mindestens eines in unterschiedlichen abschnittslängenvariablen Ausführungen radial montierbaren, geteilten Zwischenringes (12) und einem zweiten Umfangsteilstück eines Grundkörpers (11) der Falzwalze (6;7), wobei der Durchmesser des Zwischenringes (12) und des Grundkörpers (11) gegenüber dem Durchmesser der Zugringe geringfügig reduziert ist,
  • ist die Aussparung (Au) mindestens in einem mit der offenen Seite des nochmals zu falzenden Druckexemplares zusammenarbeitenden, zumindest aus jeweils einem dritten Umfangsteilstück des Zwischenringes (12) und des Zugringes (13) zusammengesetzten ersten Randbereich (R1) mindestens einer Falzwalze (6;7) angeordnet,
  • ist der zu dem Zwischenring (12) benachbarte Zugring (13) koaxial verschiebbar auf der Falzwalze (6;7) befestigt,
  • sind die mit einer der kleinsten Abschnittslänge des Druckexemplares entsprechenden, mit dem Grundkörper (11) seitlich abschließenden, Falzleiste (4;5) sowie den Zugringen (13;14), jedoch ohne Zwischenring (12) komplettierte Falzwalze (6;7) und der jeweilige einer bestimmten Abschnittslänge zugehörige Zwischenring (12), inclusive des auf diesem entfallenden Anteils der Falzleiste (4;5), einzeln unwuchtfrei.
Figure 00000001
In order to create folding rollers that enable a high folding speed to be unbalanced and easily convertible for processing print copies of different section lengths,
  • the first circumferential section (U 1 ) consists of a fold bar (4; 5) which can be exchanged in different versions with variable section lengths, as well as a respective axially parallel circumferential section of two pull rings (13; 14) adjoining the fold bar (4; 5),
  • The second circumferential section (U 2 ) consists of a second circumferential section of the pull rings (13; 14) and a second circumferential section which is axially parallel to it and adjoins the groove strip (4; 5) embedded in a groove in the circumferential direction mountable, divided intermediate ring (12) and a second peripheral section of a base body (11) of the folding roller (6; 7), the diameter of the intermediate ring (12) and the base body (11) being slightly reduced compared to the diameter of the pull rings,
  • is the cutout (Au) in at least one first edge region (R 1 ) of at least one folding roller (6;) which cooperates with the open side of the printed copy to be folded again and consists of at least one third peripheral section of the intermediate ring (12) and the pull ring (13). 7) arranged
  • the pull ring (13) adjacent to the intermediate ring (12) is fastened coaxially displaceably on the folding roller (6; 7),
  • are the folding bar (4; 5) corresponding to the smallest section length of the printed copy, which laterally closes with the base body (11), and the pull rings (13; 14), but without an intermediate ring (12), and the folding roller (6; 7) and the Each intermediate ring (12) associated with a certain section length, including the portion of the folded strip (4; 5) which is omitted on this, individually unbalanced.
