Eine insgesamt mit 1 bezeichnete Andrückwalze besteht
aus einem Tragrohr 2, welches an seinen beiden Enden 6
jeweils ein über ein Kugellager 3 gelagerten Lagerzapfen
4 aufnimmt. Die Lagerzapfen 4 sind in schwenkbaren Armen
bzw. in verfahrbaren Klebeschlitten z. B. nach der
DE 41 35 101 A1 bekannten Andrück- und Trenneinrichhtung
gelagert. Auf beiden Enden 6 des Tragrohres 2 ist
jeweils ein kreisringförmiger Deckel 7 oder Endscheibe
aufgesetzt, so daß dessen lichte Innendurchmesser auf
dem Außendurchmesser des Tragrohres 2 aufsitzt. Beide
Deckel 3 stützen mit ihrem Umfang jeweils die Enden 8
eines elastischen hohlzylinderförmigen Andrückmantels 9
ab, so daß zwischen der äußeren Mantelfläche 11 des
Tragrohres 2 und der inneren Mantelfläche 12 des Mantels
9 ein hohlzylinderförmiger Raum 13 entsteht, welcher
eine Vielzahl von luftgefüllten Zellen - alle mit 14
benannt, jedoch nicht immer bezeichnet - aufnimmt. Die
Zellen 14 können jeweils eine Zylinderform aufweisen,
aus Folie bestehen sowie flächenhaft neben - und
hintereinander (Fig. 3) auf eine flexibles
Trägermaterial 16, z. B. Folie, luftdicht aufgesetzt
sein. Das so mit gas- bzw. luftgefüllten Zellen 14
bestückte Trägermaterial 16 kann eine Breite aufweisen,
die der nutzbaren axialen Länge der Andrückwalze 1
entspricht. Das Material 14, 16 kann mehrlagig und
spiralförmig zur Rotationsachse 17 der Andrückwalze 1
auf das Tragrohr 2 aufgewickelt sein, so daß die
Seitenränder des Trägermaterials 16 innen an den
kreisringförmigen Deckeln 7 anliegen. Somit ist der Raum
13 mit kompressiblen Material 14, 16 ausgefüllt.
Derartiges Material 14, 16 kann aus handelsüblicher
Luftpolsterfolie bestehen. Die Teile 2, 3, 4, 6, 7, 8
sind zweifach vorhanden, jedoch nur einem dargestellt.
Die Zellen 14 sind in einer nicht näher bezeichneten
Vielzahl vorhanden. Periphere Zellen 14 bilden eine
Mantelfläche 28, welche als Lauffläche der Andrückwalze
1 dienen kann. Zweckmäßigerweise ist jedoch die
periphere Mantelfläche 28 der Zellen 14 von einem
elastischen Andrückmantel 9 umgeben, so daß dieser die
Lauffläche bildet. Es ist jedoch auch möglich, alle
Zellen 14 untereinander zu verbinden, z. B. mittels
rohrförmiger Verbindungen, so daß zwischen den Zellen 14
ein definierter Luftausgleich erfolgen kann.There is a total of 1 pressure roller
from a
In einem zweiten Ausführungsbeispiel ist eine insgesamt
mit 21 bezeichnete Andrückwalze dargestellt, deren
Tragrohr 2 an seinen beiden Enden 6 jeweils einen
Ringflansch 22 aufnimmt. Beide Ringflansche 22 weisen an
den einanderzugewandten Flanken 23 jeweils eine
kreisförmige Nut 24 auf, in welcher jeweils das Ende 8
eines elastischen Andrückmantels 9 befestigt ist, so daß
sich zwischen der äußeren Mantelfläche 11 des Tragrohres
2 sowie der inneren Mantelfläche 12 des elastischen
Andrückmantels 9, begrenzt von den Ringflanschen 22, ein
hohlzylinderförmiger Raum oder Zelle 13 ergibt, in
welcher mittels eines
im Andrückmantel 9
angeordneten
Ventils 26, welches als Rückschlagventil ausgebildet
sein kann, Druckluft eingeleitet werden kann. Somit ist
die Zelle 13 ebenfalls mit kompressiblen Material
ausgestattet, wobei der Luftdruck in der Zelle 13
mittels einer bekannten Druckluftquelle auffüllbar und
somit auch einstellbar ist (Fig. 4). Somit ist sowohl
eine Härte der Andrückwalze 21 als auch eine sogenannte
"Abplattung", welche beim Gegendrücken gegen eine
Vorratsrolle entsteht, einstellbar. Die Teile 22, 23, 24
sind zweifach vorhanden. Bereits im Ausführungsbeispiel
1 genannte Teile sind nicht nochmals erwähnt und
gleichermaßen ausgebildet.In a second embodiment, one is
shown with the
Nach einer anderen Ausführungsvariante des zweiten
Ausführungsbeispiels können die Enden 8 des elastischen
Andrückmantels 9 auch auf dem äußeren Umfang 27 des
Ringflansches 27 aufgeschrumpft sein.According to another variant of the second
Embodiment, the

6 dargestellten elastischen Andrückmäntel 29; 36 können
diese auf ihrer Innenseite 31 oder Außenseite 36
voneinander im Abstand a beabstandete, in peripherer
Richtung der Andrückwalze 21 umlaufende Ringe 37; 38
aufweisen (in Fig. 5 und 6 als zweites Bezugszeichen,
getrennt mittels Semikolon, bezeichnet). Eine Höhe h der
Noppen 33, 34 oder der Ringe 37, 38 entspricht
mindestens einer Dicke d des elastischen Andrückmantels
29; 36. Die Ringe 37 (Fig. 5) können an ihren oberen und
unteren Kanten abgerundet sein, so daß diese im
Querschnitt eine etwa kegelige bis kegelstumpfförmige
Form einnehmen. Die Ringe 38 sind scharfkantig
dargestellt.According to another embodiment variant of the in Fig. 5 and
6 shown
Nach einer weiteren nichtdargestellten
Ausführungsvariante kann der elastische Andrückmantel 36
auf seiner Außenseite statt der Noppen 33 voneinander im
Abstand von ca. 0,25 mal a beabstandete "Stacheln" aus
elastischem Material, z. B. Gummi, aufweisen mit einer
Höhe, welche größer ist als die Höhe h der Noppen 33, 34
oder der Ringe 37, 38.After another not shown

Es ist auch weiterhin möglich, einen elastischen
Andrückmantel 9, im Längsschnitt gesehen,
wellenlinienförmig auszubilden. Das für die elastischen
Andrückmäntel 9; 29; 36 verwendete Material kann z. B.
aus Gummi bestehen. Das für das Tragrohr 2 verwendete
Material kann aus Metall, glasfaser - oder
kohlefaserversträrktem Material bestehen.It is still possible to use an
Alle Noppen 33, 34, Ringe 37, 38 oder Stacheln sind
stoffschlüssig mit dem jeweils genannten elastischen
Andrückmantel 9, 29, 36 verbunden. All
Nach einem weiteren Ausführungsbeispiel ist eine
insgesamt mit 39 bezeichnete Andrückwalze gezeigt,
welche auf dem Tragrohr 2 mehrere, z. B. vier in axialer
Richtung 17 hintereinander angeordnete gasgefüllte
Zellen 41, 42, 43, 44 aufweist, welche jeweils mittels
eines im elastischen Andrückmantel 46 angeordnetem
Ventil 47, 48, 49, 50 separat mit Gas beaufschlagbar
ist. Damit kann, falls erforderlich, für jede Zelle 41
