Abstract

Es wird eine Halterung (9) für einen Druckwalzenzwilling (11) eines mehrere Unterwalzen (2,4) aufweisenden Streckwerkes beschrieben. Der Druckwalzenzwilling (11) enthält eine feststehende Achse (10) und zwei drehbar gelagerte Oberwalzen (3). Die Halterung (9) enthält wenigstens ein der Achse (10) des Druckwalzenzwillings (11) zugeordnetes Positionierungselement (13) und wenigstens ein Krafteinleitungselement (17), wobei das Positionierungselement (13) im Bereich der Mitte der Achse (10) des Druckwalzenzwillings (11) angeordnet ist und dem Druckwalzenzwilling (11) ein Pendeln um die Mitte (12) ermöglicht. Die Halterung (9) mit dem Druckwalzenzwilling (11) ist von den Unterwalzen (2) abhebbar. Dem Druckwalzenzwilling (11) ist wenigstens ein Fanglager (15) zur Grobpositionierung beim Aufsetzen auf die Unterwalzen (2) zugeordnet. Weiterhin kann vorgesehen sein, dass das Krafteinleitungselement (17) getrennt von dem Positionierungselement (13) angeordnet ist und dass das Fanglager (15) in dem Krafteinleitungselement (17) integriert ist.

A holder (9) for a pair of printing rolls (11) of a drafting device having a plurality of lower rollers (2, 4) is described. The printing roll twin (11) includes a fixed axis (10) and two rotatably mounted top rollers (3). The holder (9) contains at least one positioning element (13) associated with the axis (10) of the pressure roller twin (11) and at least one force introduction element (17), wherein the positioning element (13) in the region of the center of the axis (10) of the pressure roller twin (11 ) is arranged and the pressure roller twin (11) allows oscillation around the center (12). The holder (9) with the pressure roller twin (11) can be lifted from the lower rollers (2). The printing roll twin (11) is assigned at least one backup bearing (15) for coarse positioning when placed on the lower rollers (2). Furthermore, it can be provided that the force introduction element (17) is arranged separately from the positioning element (13) and that the safety bearing (15) is integrated in the force introduction element (17).
