Each angle change pot 11 has a number of parallel to one in Fig. 4 At the side facing intended installation of the Schneidradplatte 2 side of each Winkelwechselnopf 11 is formed with an angle wall 22 which is integrally formed on a parallel wall 21 and angled to the displacement axis 20, however, as in the following figures, dashed illustrated displacement axis 20 aligned parallel walls 21 perpendicular to the Schneidradplatte 2, is aligned.

Weiterhin ist aus der Darstellung gemäß Fig. 4 ersichtlich, dass die dargestellte Übergangsschneidrollenanordnung 7 als Ausführungsbeispiel einer erfindungsgemäßen Schneidrollenanordnung, wie auch die in Fig. 4 nicht dargestellten Zentrumsschneidrollenanordnungen 5, 6 als weitere Ausführungsbeispiele von erfindungsgemäßen Schneidrollenanordnungen, über eine Schneidrolleneinheit 23 verfügt, die neben der bereits in Zusammenhang mit Fig. 1 erläuterten Doppelschneidrolle 8 über einen massiven Lagerblock 24 verfügt. Der Lagerblock 24 ist entsprechend dem Winkelwechseltopf 11 mit einer Anzahl von Parallelwänden 25 ausgebildet, die parallel zu der Verschiebeachse 20 ausgerichtet und so angeordnet sind, dass sie an den nach radial innen weisenden Innenseiten der Parallelwände 21 des Winkelwechseltopfes 11 im wesentlichen spielfrei und entlang der Verschiebeachse 20 verschiebbar gelagert sind. Zum Verschieben des Lagerblockes 24 greift der Rückzugzylinder 15 über eine Verbindungseinheit 26 an der der Doppelschneidrolle 8 abgewandten Seite an dem Lagerblock 24 an.Furthermore, from the illustration according to Fig. 4 it can be seen that the illustrated transition cutting roller assembly 7 as an embodiment of a cutting roller assembly according to the invention, as well as the in Fig. 4 Not shown center cutting roller assemblies 5, 6 as further embodiments of cutting roller assemblies according to the invention, has a cutting roller unit 23, in addition to the already in connection with Fig. 1 explained double cutting roller 8 has a solid bearing block 24. The bearing block 24 is formed according to the Winkelwechselnopf 11 with a number of parallel walls 25 which are aligned parallel to the displacement axis 20 and arranged so that they at the radially inwardly facing inner sides of the parallel walls 21 of the Winkelwechselnopfes 11 substantially free of play and are slidably mounted along the displacement axis 20. To move the bearing block 24, the retraction cylinder 15 engages on the bearing block 24 via a connection unit 26 on the side facing away from the double cutting roller 8.

An dem Lagerblock 24 ist auf der der Verbindungseinheit 26 abgewandten Seite eine Winkelwand 27 ausgebildet, die wie die Winkelwand 22 des Winkelwechseltopfes 11 gegenüber der Verschiebeachse 20 abgewinkelt ausgerichtet ist. Der Lagerblock 24 trägt auf seiner der Verbindungseinheit 26 abgewandten Seite eine Lagerachse 28 der Schneidrolleneinheit 23, an der die Doppelschneidrolle 8 angebracht ist. Die Lagerachse 28 ist mit einem Ende an der Winkelwand 27 und mit dem anderen Ende an der der Winkelwand 27 gegenüberliegenden Parallelwand 25 des Lagerblockes 24 gehalten, so dass eine in Fig. 4, wie auch in den nachfolgenden Figuren, strichpunktiert dargestellte Wirkachse 29, die rechtwinklig zu der Schneidradplatte 2 ausgerichtet ist, gegenüber der Verschiebeachse 20 abgewinkelt ist.On the bearing block 24, an angle wall 27 is formed on the side facing away from the connecting unit 26, which is aligned as the angle wall 22 of the angle change pot 11 with respect to the displacement axis 20 angled. The bearing block 24 carries on its side remote from the connecting unit 26 a bearing axis 28 of the cutting roller unit 23 to which the double cutting roller 8 is mounted. The bearing shaft 28 is held at one end to the angle wall 27 and at the other end to the angle wall 27 opposite parallel wall 25 of the bearing block 24, so that a in Fig. 4 , as well as in the following figures, shown in phantom Wirkachse 29, which is aligned at right angles to the Schneidradplatte 2, opposite the displacement axis 20 is angled.

In der Darstellung gemäß Fig. 4 ist die Schneidrolleneinheit 23 in einer vorgeschobenen Arbeitsstellung angeordnet, in der nach Ausfahren des Rückzugzylinders 15 die Schneiddisken 9 über die Schneidradplatte 2 überstehen. In der Arbeitsstellung liegt der Lagerblock 24 insbesondere im Bereich seiner Winkelwand 27 und der sich an die Winkelwand 27 des Lagerblockes 24 anschließenden Parallelwand 25 formschlüssig an den entsprechenden Bereichen des Winkelwechseltopfes 11 an, so dass auf die Schneidrolleneinheit 23 in Richtung der Wirkachse 29 einwirkende Kräfte aufgrund der gegenüber der Wirkachse 29 abgewinkelten Verschiebeachse 20 teilweise in den Winkelwechseltopf 11 eingeleitet werden. Dadurch verringert sich gegenüber einer parallelen, fluchtenden Ausrichtung der Wirkachse 29 und der Verschiebeachse 20 die von den Rückzugzylinder 15 aufzunehmende Kraft.In the illustration according to Fig. 4 the cutting roller unit 23 is arranged in an advanced working position, in which, after extension of the retraction cylinder 15, the cutting discs 9 project beyond the cutting wheel plate 2. In the working position of the bearing block 24 is in particular in the region of its angular wall 27 and adjoining the angled wall 27 of the bearing block 24 parallel wall 25 positively against the corresponding areas of the Winkelwechselnopfes 11, so that on the cutting roller unit 23 in the direction of the active axis 29 forces acting due the offset relative to the axis of action 29 angled displacement axis 20 are partially introduced into the angle change pot 11. As a result, the force to be absorbed by the retraction cylinder 15 is reduced relative to a parallel, aligned alignment of the axis of action 29 and the displacement axis 20.
