Description

Die Erfindung betrifft eine Walze zum Umlenken, Führen oder Bearbeiten von band- oder bahnförmigem Material, deren aus einer Gummi-oder Kunststoffschicht bestehender Mantel parallel zur Walzenachse verlaufende, durchgehende Stäbe insbesondere aus Federstahl enthält, die an den Stirnseiten der Walze an in Pendellagern auf der Walzenachse gelagerten Flanschringen befestigt sind, deren Drehebene unter Beibehaltung der Drehachse mittels einer Verstellvorrichtung gegenüber dem ursprünglichen Drehebene neigbar ist.The invention relates to a roller for deflecting, guiding or processing of strip-shaped or web-shaped material, the casing of which consists of a rubber or plastic layer and comprises continuous rods running parallel to the roller axis, in particular made of spring steel, which are mounted on the end faces of the roller in self-aligning bearings on the Flange rings mounted on the roller axis are fixed, the plane of rotation of which can be inclined relative to the original plane of rotation while maintaining the axis of rotation by means of an adjusting device.

Mit einer derartigen Walze ist es möglich, die Drehebene des Mantels unter Beibehaltung der Drehachse gegenüber der ursprünglichen Drehebene zu neigen. Hierdurch verformt sich der Mantel bei jeder Umdrehung derart in sich, daß über die gesamte axiale Länge des Mantels alle Bandanlaufpunkte gegenüber den Bandablaufpunkten seitlich verlagert werden. Die seitliche Verlagerung macht das unter Reibungsschluß an der Walze anliegende band- oder bahnförmige Material mit, so daß eine gezielte seitliche Verlagerung möglich ist. Zum Zentrieren des Bandes oder der Bahn kann man beispielsweise mittels geeigneter und bekannter Meßvorrichtungen die Kanten des einlaufenden oder ablaufenden Bandes abtasten und in Abhängigkeit von den Signalen dieser Meßvorrichtung die Neigung der Drehebene des Mantels der Walze mittels der Verstellvorrichtung entsprechend korrigieren.With such a roller, it is possible to incline the plane of rotation of the jacket while maintaining the axis of rotation relative to the original plane of rotation. As a result, the jacket deforms in itself during each revolution in such a way that all tape contact points are laterally displaced with respect to the tape outlet points over the entire axial length of the jacket. The lateral displacement makes the band-like or web-shaped material which is in frictional engagement with the roller, so that a targeted lateral displacement is possible. To center the belt or the web, one can, for example, use suitable and known measuring devices to scan the edges of the incoming or outgoing belt and, depending on the signals from this measuring device, correct the inclination of the plane of rotation of the jacket of the roller accordingly using the adjusting device.

Bei einer nach dem Stande der Technik (US-PS 2 643 116) bekannten Walze der genannten Art ist der aus Gummi bestehende Mantel auf einen zylindrischen Walzenkörper aufvulkanisiert, so daß eine Verformung des Mantels unter starker Scherbelastung der Gummimasse in nur ganz geringem Maße möglich ist. Außerdem müssen wegen der starken Scherkräfte von der Verstellvorrichtung außerordentlich hohe Kräfte aufgebracht werden, um die Drehebene der Flanschringe und damit die Drehebene des Mantels zu neigen. Schließlich führen die hohen Scherkräfte in der Gummi- oder Kunststoffmasse alsbald zu Überlastungen und Zerstörungen.In a roller of the type mentioned, known from the prior art (US Pat. No. 2,643,116), the rubber jacket is vulcanized onto a cylindrical roller body, so that deformation of the jacket under strong shear stress on the rubber compound is only possible to a very small extent . In addition, because of the strong shear forces, the adjusting device has to apply extremely high forces in order to incline the plane of rotation of the flange rings and thus the plane of rotation of the jacket. After all, the high shear forces in the rubber or plastic mass soon lead to overloading and destruction.

Weiterhin ist es nach dem Stande der Technik (US-PS 3 344493, FR-PS 1 252 374) bei einer Walze der genannten bzw. ähnlicher Art bekannt, unterhalb des Mantels einen auf der Achse der Walze gelagerten Stützzylinder anzuordnen, der den Mantel über die gesamte Länge von innen her abstützt. Die Anordnung eines solchen Stützzylinders innerhalb des Mantels hat erhebliche Nachteile. Bei einer Neigung der Drehebene des Mantels ergibt sich bei jeder Umdrehung der Walze eine axiale Relativverschiebung zwischen dem Mantel und dem Stützzylinder. Da der Mantel ständig an der Walze anliegt, ergibt sich eine ständige Reibung zwischen dem Stützzylinder und dem Mantel, die zur Erwärmung des Materials und natürlich auch zu Verschleiß führt. Diese Reibung ist um so heftiger, je stärker der Mantel gegen die Oberfläche des Stützzylinders angepreßt wird. Der Verschleiß ist deshalb besonders groß, wenn das um die Walze umlaufende Material - wie in der Praxis oft üblich - unter einer verhältnismäßig großen Zugspannung steht, so daß starke radial gerichtete Kräfte auf den Mantel der Walze einwirken. Die Reibung zwischen dem Mantel und dem Stützzylinder behindert natürlich auch die gleichmäßige Verformung des Mantels während des Umlaufs, und zwar um so mehr, je stärker die Reibungskräfte zwischen dem Mantel und dem Stützzylinder sind.Furthermore, it is known according to the prior art (US Pat. No. 3,344,493, French Pat. No. 1,252,374) in the case of a roll of the type mentioned or similar to arrange a support cylinder, which is mounted on the axis of the roll and which covers the casing, below the casing supports the entire length from the inside. The arrangement of such a support cylinder within the jacket has considerable disadvantages. With an inclination of the plane of rotation of the jacket, there is an axial relative displacement between the jacket and the support cylinder with each revolution of the roller. Since the jacket is constantly in contact with the roller, there is constant friction between the support cylinder and the jacket, which leads to heating of the material and, of course, to wear. This friction is all the more violent, the more the jacket is pressed against the surface of the support cylinder. The wear is therefore particularly great when the material revolving around the roller - as is often the case in practice - is under a relatively high tensile stress, so that strong radially directed forces act on the jacket of the roller. The friction between the jacket and the support cylinder naturally also hinders the uniform deformation of the jacket during the rotation, and the more the greater the frictional forces between the jacket and the support cylinder.

Nach dem Stande der Technik (US-PS 3 248 031) ist es auch bekannt, den aus einer ein- - teiligen Gummi- oder Kunststoffschicht bestehenden Mantel einer in sich verformbaren Walze durch eine in Umfangsrichtung des Mantels verlaufende Schraubenfeder zu verstärken. Bei diesem vorbekannten Stand der Technik weist der Mantel jedoch keine in Längsrichtung verlaufenden Stäbe auf, so daß die Walze gegen radiale Kräfte nachgiebig ist und deshalb von zwei außenliegenden, sich über die gesamte axiale Länge erstreckenden Stützzylindern abgestützt werden muß. Diese Stützzylinder behindern, ähnlich wie die innenliegenden Stützzylinder beim zuvor diskutierten Stand der Technik, die Verformung des Mantels und benötigen darüber hinaus Platz am Außenumfang der Walze, so daß diese Walze nur schlecht zum Umlenken von bahn- oder bandförmigem Material verwendet werden kann.According to the prior art (US Pat. No. 3,248,031), it is also known to reinforce the casing, which consists of a one-piece rubber or plastic layer, of a roll which can be deformed in itself by a helical spring running in the circumferential direction of the casing. In this known prior art, however, the jacket has no longitudinally extending rods, so that the roller is flexible against radial forces and must therefore be supported by two external support cylinders which extend over the entire axial length. These support cylinders, like the internal support cylinders in the previously discussed prior art, hinder the deformation of the jacket and also require space on the outer circumference of the roller, so that this roller can only be used poorly for deflecting web or strip material.

Schließlich ist aus der bereits genannten US-PS 3 344493 eine Breitstreckwalze bekannt, bei der der Mantel aus einer Vielzahl von einzeln in Gummi oder Kunststoff eingebetteten elastischen Stäben besteht, die von innen von einem Stützzylinder abgestützt sind und untereinander durch in Umfangsrichtung der Walze schraubenlinienförmig verlaufende Seile oder Drähte verbunden sind. Diese Seile oder Drähte sollen verhindern, daß die elastischen Stäbe unter Einwirkung der Zentrifugalkräfte von dem Stützzylinder abheben und sich nach außen biegen.Finally, from the already mentioned US Pat. No. 3,344,493, an spreader roll is known, in which the casing consists of a plurality of elastic rods individually embedded in rubber or plastic, which are supported from the inside by a support cylinder and which extend helically with one another in the circumferential direction of the roll Ropes or wires are connected. These ropes or wires are intended to prevent the elastic rods from lifting off the support cylinder under the action of centrifugal forces and from bending outwards.

Aufgabe der Erfindung ist es, bei einer Walze gemäß dem Gattungsbegriff des Patentanspruchs 1 den Mantel biegesteif und gewölbesteif auszubilden, damit ein gesonderter Stützzylinder nicht erforderlich ist. Dabei soll die Walze trotz ihrer Biegesteifigkeit und Gewölbesteifigkeit parallel zur Zylinderachse unbehindert verformbar bleiben.The object of the invention is to provide a rigid and arch-rigid jacket for a roller according to the preamble of claim 1, so that a separate support cylinder is not required. Despite its bending stiffness and arch stiffness, the roller should remain freely deformable parallel to the cylinder axis.

Zur Lösung dieser Aufgabe schlägt die Erfindung ausgehend von einer Walze gemäß dem Gattungsbegriff des Patentanspruchs 1 vor, daß die Gummi- oder Kunststoffschicht des Mantels zusätzlich durch in Umfangsrichtung verlaufende Verstärkungseinlagen in Form von Ringen oder einer Schraubenfeder verstärkt ist, wobei die den Mantel tragenden Stäbe und die Verstärkungseinlagen so bemessen sind, daß der Mantel für die auftretenden Belastungen ausreichend biege- und gewölbesteif ist.To achieve this object, the invention proposes, starting from a roller according to the preamble of claim 1, that the rubber or plastic layer of the jacket is additionally reinforced by reinforcing inserts in the form of rings or a coil spring running in the circumferential direction, the rods and the reinforcing inserts are dimensioned so that the jacket is sufficiently resistant to bending and arching for the loads that occur.

Die Walze gemäß der Erfindung hat den Vorteil, daß sie ohne den Mantel über seine Länge abstützende Stützzylinder auskommt. Der mit einem solchen Stützzylinder verbundene konstruktive Mehraufwand und der Verschleiß werden also vermieden. Dadurch, daß der Mantel ausschließlich von den auf der Walzenachse mittels Pendellagern gelagerten Flanschringen getragen wird, kann er sich während seines Umlaufs um die Walzenachse von äußeren Kräften unbehindert verformen, so daß eine sehr genaue Steuerung des umlaufenden bandförmigen Materials möglich ist.The roller according to the invention has the advantage that it does without the supporting cylinder supporting the jacket over its length. The additional design effort and wear associated with such a support cylinder are thus avoided. Because the jacket is only supported by the flange rings mounted on the roller axis by means of self-aligning bearings, it can deform unhindered by external forces during its rotation around the roller axis, so that very precise control of the circulating band-shaped material is possible.

Eine besonders vorteilhafte Weiterbildung der Walze gemäß der Erfindung sieht vor, daß die Wellenachse an einem über ein Pendellager hinausstehenden Ende mit einem exzentrisch angeordneten Zapfen versehen ist, auf welchem eine mit einer exzentrischen Bohrung versehene Exzenterbuchse verdrehbar gelagert ist, welche über ein Pendellager und eine Flanschbuchse an einer Flanschbuchse des benachbarten Flanschringes abgestützt ist. Die derart ausgebildete Exzenterverstellvorrichtung ermöglicht es auf einfache Weise, die Drehebene der Ringflansche und damit die Drehebene des in sich verformbaren elastischen Mantels in bezug auf die feststehende Walzenachse in beliebigen Richtungen zu neigen. Hierzu braucht nur die Exzenterbuchse auf dem exzentrischen Zapfen relativ zur Walzenachse verdreht zu werden. Diese Ausführungsform der Verstellvorrichtung ist besonders einfach im Aufbau und dementsprechend unempfindlich.A particularly advantageous development of the roller according to the invention provides that the shaft axis is provided at one end projecting beyond a self-aligning bearing with an eccentrically arranged pin, on which an eccentric bushing provided with an eccentric bore is rotatably mounted, which via a self-aligning bearing and a flange bushing is supported on a flange bushing of the adjacent flange ring. The eccentric adjusting device designed in this way makes it possible in a simple manner to incline the rotational plane of the ring flanges and thus the rotational plane of the deformable elastic jacket in any direction with respect to the fixed roller axis. For this purpose, only the eccentric bush on the eccentric pin needs to be rotated relative to the roller axis. This embodiment of the adjustment device is particularly simple in construction and accordingly insensitive.

Vorteilhaft kann die Walze gemäß der Erfindung auch zum Breitstrecken von band- oder bahnförmigem Material eingesetzt werden. Um einen nach den Rändern hin progressiven Breitungseffekt zu erzielen, sind die in Längsrichtung des Mantels verlaufenden Stäbe gewellt oder geknickt ausgebildet, wie an sich bekannt (US-PS 3344493), wobei die Höhe der Wellen oder Knicke in den Stäben in der Walzenmitte kleiner als in den Endabschnitten der Walze ist und jedem Ende der Walze eine Verstellvorrichtung zugeordnet ist. Die gewellten oder geknickten Stäbe erteilen dem Mantel dort, wo die Knicke oder Wellen höher ausgebildet sind, nämlich in den Randbereichen, eine stärkere seitliche Verlagerung, als in dem mittleren Abschnitt, wo die Knikke oder Wellen niedriger ausgebildet sind und die Stäbe infolgedessen einen höheren Verformungswiderstand haben. Auf diese Weise kann das Breitstreckverhalten der Walze gemäß der Erfindung der tatsächlichen seitlichen Breitung des Bandes oder der Bahn optimal angepaßt werden.Advantageously, the roller according to the invention can also be used to spread out strip or web material. In order to achieve a progressive widening effect towards the edges, the bars running in the longitudinal direction of the jacket are corrugated or kinked, as is known per se (US Pat. No. 3,344,493), the height of the waves or kinks in the bars in the middle of the roll being less than is in the end portions of the roller and an adjusting device is assigned to each end of the roller. The corrugated or kinked bars impart a greater lateral displacement to the jacket where the kinks or waves are formed higher, namely in the edge areas, than in the central section where the kinks or waves are formed lower and the bars consequently have a higher resistance to deformation to have. In this way, the spreading behavior of the roller according to the invention can be optimally adapted to the actual lateral spreading of the strip or web.

Zum gleichen Zweck kann zusätzlich der in sich elastisch verformbare Mantel in der Walzenmitte dicker als in den Endabschnitten ausgebildet sein. Durch diese Maßnahme verformt sich der Mantel in den Randbereichen stärker als in den mittleren Bereichen.For the same purpose, the elastically deformable jacket can additionally be made thicker in the middle of the roll than in the end sections. As a result of this measure, the jacket deforms more in the edge regions than in the middle regions.

Ein Ausführungsbeispiel einer Walze gemäß der Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Es zeigt

An embodiment of a roller according to the invention is explained below with reference to the drawing. It shows
  • 1 is a schematic diagram of the roller according to the invention in side view,
  • 1 shows a longitudinal section through a specific embodiment of a roller according to the invention,
  • 3 shows a section through one side of the jacket of a roll designed as an spreader roll according to the invention,
  • Fig. 4 is a plan view of a shaft provided with waves.

In Fig. 1 ist der Mantel der Walze in seiner Gesamtheit mit dem Bezugszeichen 1 bezeichnet. Die Walze selbst ist um eine Achse 2 drehbar. Der Mantel 1 ist durch seitlich angreifende Kräfte (Pfeil 3) einer in Fig. 1 nicht näher dargestellten Verstellvorrichtung parallel zur Achse 2 in sich verformbar, derart, daß die Drehebene E' des Mantels unter Beibehaltung der ursprüngli- chen Drehachse gegen die ursprüngliche Drehebene E (in Fig. 1 gestrichelt eingezeichnet) geneigt verläuft. Durch die ständig beim Umlauf um die Achse 2 erfolgende Verformung des Mantels 1 in sich erfahren die Ablaufpunkte P2 eines von der Walze ablaufenden Bandes gegenüber den Auflaufpunkten P1 einen seitlichen Versatz um einen Betrag x. Dieser seitliche Versatz x kann durch die jeweilige Neigung der Drehebene E' beliebig eingestellt werden. Die Drehebene E' kann selbstverständlich auch in der entgegengesetzten Richtung gegen die ursprüngliche Drehebene E geneigt werden, so daß der Versatz x nach der anderen Seite erfolgt.In Fig. 1 the shell of the roller is designated in its entirety with the reference number 1. The roller itself is rotatable about an axis 2. The jacket 1 is an adjusting device not shown in Figure 1 deformed by lateral forces acting (3 arrow) parallel to the axis 2 in it, such that the plane of rotation E 'of the sheath while maintaining the Original Art -. Chen axis of rotation against the original plane of rotation E (shown in dashed lines in Fig. 1) inclined. As a result of the deformation of the casing 1, which constantly takes place around the axis 2, the run-off points P2 of a strip running off the roll experience a lateral offset by an amount x compared to the run-on points P1. This lateral offset x can be set as desired by the respective inclination of the plane of rotation E '. The plane of rotation E 'can of course also be inclined in the opposite direction to the original plane of rotation E, so that the offset x takes place on the other side.

In Fig. 1 ist die Neigung der Drehebene E' gegen die ursprüngliche Drehebene E zur Verdeutlichung übertrieben dargestellt. Tatsächlich reichen sehr viel kleinere Neigungswinkel aus.In Fig. 1, the inclination of the plane of rotation E 'against the original plane of rotation E is exaggerated for clarity. In fact, much smaller angles of inclination are sufficient.

Beim in Fig. 2 dargestellten konkreten Ausführungsbeispiel der Walze besteht der Mantel 1 aus abriebfestem, dynamisch hoch beanspruchbarem Kunststoff oder Gummi und ist durch Bewehrungseinlagen in Form von axial verlaufenden Stäben 4 und einer in Umfangsrichtung verlaufenden Schraubenfeder 5 verstärkt. Die Stäbe 4 sind in Umfangsrichtung in gleichen Abständen zueinander verteilt und bestehen ebenso wie die Schraubenfeder 5 vorzugsweise aus Federstahl. An die Stelle der Schraubenfeder 5 können auch entsprechend angeordnete und ausgebildete separate Ringe treten. Die Stäbe 4 sind stirnseitig in Flanschringen 6 gelagert, zwischen denen sich die Gummi- oder Kunststoffschicht des Mantels 1 erstreckt und die mit Flanschbuchsen 7 festverbunden sind. Diese Flanschbuchsen 7 sind mittels Pendellagern 8 auf der Achse 2 gelagert. Die in bezug auf ihre räumliche Anordnung feststehende Achse 2 weist an einem Ende einen über das Pendellager 8 hinausstehenden, exzentrisch angeordneten Zapfen 9 auf, auf welchem eine mit einer exzentrischen Bohrung versehene Exzenterbuchse 10 verdrehbar ist. Die Exzenterbuchse 10 ist außerdem mittels eines zweiten Pendellagers 11 an einem Flanschring 12 gelagert, welcher mit dem Flanschring 6 starr verbunden ist. Zwischen den beiden Pendellagern 8 undIn the specific exemplary embodiment of the roller shown in FIG. 2, the jacket 1 consists of abrasion-resistant, dynamically highly stressable plastic or rubber and is reinforced by reinforcement inserts in the form of axially extending bars 4 and a helical spring 5 extending in the circumferential direction. The rods 4 are distributed at equal distances from one another in the circumferential direction and, like the coil spring 5, are preferably made of spring steel. Correspondingly arranged and designed separate rings can also take the place of the coil spring 5. The rods 4 are mounted on the end face in flange rings 6, between which the rubber or plastic layer of the jacket 1 extends and which are firmly connected to flange bushings 7. These flange bushings 7 are mounted on the axle 2 by means of self-aligning bearings 8. The axis 2, which is fixed with respect to its spatial arrangement, has at one end an eccentrically arranged pin 9 which projects beyond the self-aligning bearing 8 and on which an eccentric bushing 10 provided with an eccentric bore can be rotated. The eccentric bush 10 is also supported by a second self-aligning bearing 11 on a flange ring 12 which is rigidly connected to the flange ring 6. Between the two spherical bearings 8 and

1.1 befindet sich eine Distanzhülse 13. Die Achse 2 ist an ihren Enden in feststehenden Lagerbökken 14 gelagert.1.1 there is a spacer sleeve 13. The axis 2 is supported at its ends in fixed bearing blocks 14.

Die aus Fig. 2 hervorgehende Verstellvorrichtung funktioniert wie folgt: Beim Verdrehen der Exzenterbuchse 10 relativ zum exzentrisch an der Achse 2 sitzenden Zapfen 9 verlagert sich die Exzenterbuchse 10 senkrecht zur Achse 2 und übt über das Pendellager 11 auf die Flanschbuchse 7 und den damit verbundenen Flanschring 6 ein Moment um die Pendelachse des Pendellagers 8 aus, so daß die Ebene des Flanschringes 6 geringfügig aus der dargestellten Lage verkippt wird. Die Verkippbewegung (Neigung) überträgt sich mittels der Stäbe 4 auf den gesamten Mantel 1 mitsamt dem gegenüberliegenden Flanschring 6. Bei verkippter Stellung (Neigung) des Flanschringes verformt sich der gesamte Mantel 1 bei jeder Umdrehung parattet zur Achse 2 in sich selbst derart, daß sich die Einlaufpunkte P1 und die Ablaufpunkte P2 gegeneinander verlagern, wie oben anhand der Fig. 1 erläutert worden ist. Durch ein entsprechendes Verdrehen der Exzenterbuchse 10 einerseits und der Achse 2 andererseits kann eine Neigung des Flanschringes 6 in praktisch jede denkbare Richtung eingestellt werden.The adjustment device shown in FIG. 2 functions as follows: When the eccentric bushing 10 is rotated relative to the pin 9 eccentrically located on the axis 2, the eccentric bushing 10 is displaced perpendicular to the axis 2 and exerts via the self-aligning bearing 11 on the flange bushing 7 and the associated flange ring 6 a moment about the pendulum axis of the self-aligning bearing 8, so that the plane of the flange ring 6 is tilted slightly from the position shown. The tilting movement (inclination) is transmitted by means of the rods 4 to the entire casing 1 together with the opposite flange ring 6. When the flange ring is in a tilted position (inclination), the entire casing 1 deforms with each revolution to the axis 2 in such a way that Shift the entry points P1 and the discharge points P2 against each other, as has been explained above with reference to FIG. 1. By a corresponding rotation of the eccentric bush 10 on the one hand and the axis 2 on the other hand, an inclination of the flange ring 6 can be set in practically any conceivable direction.

Die relative Verdrehung der beiden Teile gegeneinander kann ebenfalls von einem entsprechenden Meßgerät her gesteuert werden, welches die Abweichungen vom gewollten Bandlauf feststellt und entsprechende Korrektursignale gibt.The relative rotation of the two parts with respect to one another can also be controlled by a corresponding measuring device, which detects the deviations from the desired strip travel and gives corresponding correction signals.

Falls die in Fig. 2 dargestellte Walze als Breitstreckwalze eingesetzt werden soll, sind an beiden axialen Enden der Walze Exzenter-Einstellvorrichtungen vorgesehen, wie in Fig. 2 nur am rechten axialen Ende der Walze dargestellt ist, und die Stäbe 4 sind mit Wellen oder Knicken 4a versehen, deren Höhe gegebenenfalls nach den Rändern hin zunimmt (siehe Fig.4). Hierdurch können die Stäbe 4 in den Randbereichen einen etwas kleineren Verformungswiderstand als in den mittleren Bereichen erhalten, so daß sich in den Randbereichen die Neigung des Flanschringes 6 stärker auf den Mantel auswirkt, als in den mittleren Bereichen. Um in den Randbereichen eine stärkere Verformung des Mantels zu erzielen, kann die Wanddicke des Mantels zur Mitte hin zunehmen, wie aus Fig. 3 ersichtlich ist.If the roller shown in Fig. 2 is to be used as an spreader roller, eccentric adjusting devices are provided on both axial ends of the roller, as shown in Fig. 2 only at the right axial end of the roller, and the bars 4 are with waves or kinks 4a, the height of which may increase towards the edges (see Fig. 4). As a result, the rods 4 in the edge regions can receive a somewhat smaller resistance to deformation than in the central regions, so that the inclination of the flange ring 6 has a greater effect on the jacket in the edge regions than in the central regions. In order to achieve a greater deformation of the jacket in the edge regions, the wall thickness of the jacket can increase towards the center, as can be seen from FIG. 3.
