Definitions
- the invention relates to a web treatment apparatus, in particular for a fibrous web, with at least one roller and at least two circulating flexible bands guided over partial circumferences of the roller.
- the invention is described below by way of example for a calender for smoothing paper and board webs.
- the invention is also conceivable, for example, in the press section of a paper machine or in the treatment of other materials such as films.
- band is also to be understood as meaning a very flexible jacket of a shoe roller clamped at its axial ends
- the state of the art is the DE 10157691 A1 to call. In this publication, two strips are passed over subsections of a roller.
- a calender in which a web is smoothed between a roller and a circulating metal band which wraps around the roller over a partial circumference.
- the summarized object of the invention is therefore to provide a web treatment device which acts on both sides of a web in the same way with pressure and heat in long treatment zones.
- the object is achieved by a web treatment apparatus whose web running path of the web runs over a roller circumferential section between two belts and in which the web can be acted upon in this at least 80 mm long treatment zone with pressures between 0.1 and 100 MPa.
- the web is guided between two, preferably similar bands.
- materials with the same roughness are on both sides of the web, resulting in a uniform smoothness on both sides.
- the belt tensions allow compressive forces in the region of the deflection of the belts, that is, on a roller peripheral section, which is referred to as a treatment zone, on the web, which bring a sufficient load for a web treatment, for example for a calendering or for dewatering. This is especially true for paper or board webs that do not require high pressure loads, ie in the range of 0.1 to 10 MPa.
- the bands are made of plastic or alternatively of metal, in particular steel. Both materials offer advantages as well as disadvantages depending on the web to be treated.
- a plastic band is cheaper and produces by its elasticity a more uniform compaction of the web.
- the metal band is smoother to produce (with the smoothness on the web transmits) and wear-resistant.
- rollers are provided for the circulating belts and that the roller is arranged so that it deflects the straight course of at least one belt between two guide rollers in order to create a treatment zone.
- the band is stretched over the guide rollers, at least one of which is displaceable. In this volume, the roller "dips". Depending on the depth of immersion result in different lengths and adjustable in this way treatment zones.
- the tension in the belt can be used to control the pressure on the web in the treatment zone.
- At least two rollers are provided, in which the web runs in each case over a roller circumferential section between two belts. In this way it is possible to satinize the web once up and once down in a treatment zone. Any heat input or output is also equalized.

- the bands take over a heat-insulating function or over the cross-profile temperature-compensating function, depending on whether the bands are made of plastic or metal.
- both rollers deflect the straight course of at least one band between two guide rollers to create two treatment zones.
- the overlapping belts make the system only insignificantly longer, but one gains a second treatment zone in which a pressure on the web can be set independently of the first one.
- the deflection and thus the wrap angle is adjustable via adjusting devices for at least one roller.
- the pressures and the length of the treatment zone can be varied.
- Such Walzenverstell pleaseden are known from the calender construction sufficiently.
- hydraulic cylinders engage below the bearings to move the roller axis.
- the bands approach each other in the direction of the web travel path in front of the treatment zone and thus form a funnel-like web inlet section. This results in a very simple web presentation, for example after a web break.
- At least one roller and / or alternatively at least one belt can be heated. Heated rolls are well known in papermaking. In the event that it is a steel strip, the strip can simply be made via an inductive external heating with which the temperature can additionally be profiled over the transverse profile. Preferred surface temperatures for the treatment of a paper web are between 40 and 300 ° C.
- At least one roller has an adjustability in its bending.
- Such rolls are also known as rolls with hydrostatic support elements or in the form of so-called S-rolls.
- S-rolls The use of such rolls offers the advantage that profile problems, for example in the bulk of the web to be treated, can be compensated.
- FIGS. 1 to 3 show schematic representations of the web treatment device according to the invention.

- the second belt 6 rotates around a roller 3 and a guide roller 10. All of the rollers 3, 4 are preferably driven by electric motors in a manner not shown.
- This "immersion” via an adjusting device 11 of the roller 3, 4, which is exemplified as a hydraulic cylinder which acts on the axis of the roller 4, is shown. This results in a peripheral portion ⁇ on the roller 3, 4, in which both bands 5, 6 abut the roller 3, 4.
- the web 2 is located between the belts 5, 6. It is supplied via a funnel-shaped inlet section 12, which is formed by the belts 5, 6 at the entrance of the web treatment device. Subsequent to the inlet section 12, the bands 5, 6 run parallel over a part of their total length and form a kind of sandwich with the web in the middle.
- a treatment zone 9 with pressures of between 0.1 and 100 MPa is applied to the web due to the tensile stress in the belts.
- an additional force transducer 15 provide, as he exemplified in the form of hydrostatic support elements in a roller 3 in FIG. 2 is shown.
- To equalize the compaction of the web can be ensured in a manner not shown that the surface of at least one roller is provided with an elastic coating.
- the bands 5, 6 are made of the same material.
- metal bands are provided with a smooth surface.
- plastic bands are possibly better suited. The web is thus applied on both sides with the same surface quality.
- a roller 3, 4 be heated from the inside, which in Fig. 1 is indicated by the peripheral bores 13 in the roller 4, through which a heat transfer fluid can be passed.

Abstract
Description
Die Erfindung betrifft eine Bahnbehandlungsvorrichtung, insbesondere für eine Faserstoffbahn, mit wenigstens einer Walze und wenigstens zwei über Teilumfänge der Walze geführte umlaufende flexible Bänder.The invention relates to a web treatment apparatus, in particular for a fibrous web, with at least one roller and at least two circulating flexible bands guided over partial circumferences of the roller.
Im Folgenden wird die Erfindung beispielhaft für einen Kalander zur Glättung von Papier- und Kartonbahnen beschrieben. Die Erfindung ist aber beispielsweise durchaus auch in der Pressenpartie einer Papiermaschine oder bei der Behandlung anderer Materialien wie Folien denkbar.The invention is described below by way of example for a calender for smoothing paper and board webs. However, the invention is also conceivable, for example, in the press section of a paper machine or in the treatment of other materials such as films.
Da im Rahmen der Erfindung unter dem Begriff Band auch ein an seinen axialen Enden eingespannter, sehr flexibler Mantel einer Schuhwalze verstanden werden soll, ist als Stand der Technik die
In der
Dieser Stand der Technik hat den Nachteil, dass die Bahn auf beiden Seiten ungleichmäßig behandelt wird. Um die andere Seite der Bahn genauso behandeln zu können, muss der ersten eine zweite, spiegelverkehrte Einrichtung nachgeschaltet werden. Es ist also das erste Ziel der Erfindung diese ungleichmäßige Behandlung von Bahnseiten zu vermeiden bzw. die gleichmäßige Behandlung in einer Behandlungsvorrichtung zu vereinen.This prior art has the disadvantage that the web is treated unevenly on both sides. In order to be able to treat the other side of the web in the same way, the first must be followed by a second, mirror-inverted device. It is therefore the first object of the invention to avoid this uneven treatment of web pages or to unite the uniform treatment in a treatment device.
Ansatzweise wird dieser Aufgabe in der
Die zusammengefasste Aufgabe der Erfindung ist es demnach, eine Bahnbehandlungsvorrichtung zu schaffen, die beide Seiten einer Bahn in gleicher Weise mit Druck- und Wärme in langen Behandlungszonen beaufschlagt.The summarized object of the invention is therefore to provide a web treatment device which acts on both sides of a web in the same way with pressure and heat in long treatment zones.
Die Aufgabe wird durch eine Bahnbehandlungsvorrichtung gelöst, deren Bahnlaufpfad der Bahn über einen Walzenumfangsabschnitt zwischen zwei Bändern verläuft und bei der die Bahn in dieser mindestens 80 mm langen Behandlungszone mit Drücken zwischen 0,1 und 100 MPa beaufschlagbar ist.The object is achieved by a web treatment apparatus whose web running path of the web runs over a roller circumferential section between two belts and in which the web can be acted upon in this at least 80 mm long treatment zone with pressures between 0.1 and 100 MPa.
Über den Umfangsabschnitt der Walze wird die Bahn zwischen zwei, vorzugweise gleichartigen Bändern geführt. Auf diese Weise liegen auf beiden Seiten der Bahn Materialien mit gleicher Rauigkeit an, was zu einer gleichförmigen Glätte auf beiden Seiten führt. Die Bandspannungen ermöglichen Druckkräfte im Bereich der Umlenkung der Bänder, also auf einem Walzenumfangsabschnitt, der als Behandlungszone bezeichnet ist, auf die Bahn, die für eine Bahnbehandlung, beispielsweise für eine Satinage oder zur Entwässerung, eine ausreichende Belastung mitbringen. Dies gilt insbesondere für Papier- oder Kartonbahnen, die keine hohen Druckbeaufschlagungen, also im Bereich von 0,1 bis 10 MPa, benötigen.Over the peripheral portion of the roller, the web is guided between two, preferably similar bands. In this way, materials with the same roughness are on both sides of the web, resulting in a uniform smoothness on both sides. The belt tensions allow compressive forces in the region of the deflection of the belts, that is, on a roller peripheral section, which is referred to as a treatment zone, on the web, which bring a sufficient load for a web treatment, for example for a calendering or for dewatering. This is especially true for paper or board webs that do not require high pressure loads, ie in the range of 0.1 to 10 MPa.
Mit der Erfindung sind aber auch höherwertige graphische Papiere satinierbar, wenn Zusatzdruckgeber im Bereich der Behandlungszone eingerichtet sind, die Druckspannungen bis 100 MPa ermöglichen. In Versuchen hat sich gezeigt, dass Behandlungszonen in einem Walzenumfangsabschnitt ab einer Länge von 80 mm besonders gute Resultate in Bezug auf Satinageergebnisse (Glätte, Bulk, Zweiseitigkeit) erbringen, wenn die Bahn zwischen zwei gleichartigen Bändern geführt ist.With the invention but also higher-quality graphic papers are satin, if additional pressure sensors are set up in the treatment zone, the compressive stresses allow up to 100 MPa. Experiments have shown that treatment zones in a roll peripheral section from a length of 80 mm provide particularly good results in terms of calendering results (smoothness, bulk, two-sidedness) when the web is guided between two identical belts.
Es ist von Vorteil, wenn die Bänder aus Kunststoff bzw. alternativ aus Metall, insbesondere Stahl, bestehen. Beide Materialen bieten Vor-, aber auch Nachteile in Abhängigkeit von der zu behandelnde Bahn. Ein Kunststoffband ist preiswerter und erzeugt durch seine Elastizität eine gleichmäßigere Verdichtung der Bahn. Das Metallband ist glatter herstellbar (wobei sich die Glätte auf die Bahn überträgt) und verschleißfester.It is advantageous if the bands are made of plastic or alternatively of metal, in particular steel. Both materials offer advantages as well as disadvantages depending on the web to be treated. A plastic band is cheaper and produces by its elasticity a more uniform compaction of the web. The metal band is smoother to produce (with the smoothness on the web transmits) and wear-resistant.
Es ist günstig, wenn für die umlaufenden Bänder Leitwalzen vorgesehen sind und dass die Walze so angeordnet ist, dass sie den geraden Verlauf wenigstens eines Bandes zwischen zwei Leitwalzen ablenkt um eine Behandlungszone zu schaffen. Das Band wird über die Leitwalzen, von denen wenigstens eine verschiebbar ist, gespannt. In dieses Band "taucht" die Walze ein. Je nach Eintauchtiefe ergeben sich unterschiedlich lange und auf diese Weise einstellbare Behandlungszonen. Über die Zugspannung im Band kann der Druck auf die Bahn in der Behandlungszone gesteuert werden.It is favorable when guide rollers are provided for the circulating belts and that the roller is arranged so that it deflects the straight course of at least one belt between two guide rollers in order to create a treatment zone. The band is stretched over the guide rollers, at least one of which is displaceable. In this volume, the roller "dips". Depending on the depth of immersion result in different lengths and adjustable in this way treatment zones. The tension in the belt can be used to control the pressure on the web in the treatment zone.
Vorzugsweise sind wenigstens zwei Walzen vorgesehen, bei denen die Bahn jeweils über einen Walzenumfangsabschnitt zwischen zwei Bändern verläuft. Auf diese Weise ist es möglich, die Bahn einmal nach oben und einmal nach unten gekrümmt in einer Behandlungszone zu satinieren. Ein eventueller Wärmezu- oder -abfluss wird ebenfalls vergleichmäßigt.Preferably, at least two rollers are provided, in which the web runs in each case over a roller circumferential section between two belts. In this way it is possible to satinize the web once up and once down in a treatment zone. Any heat input or output is also equalized.
Es ist von Vorteil, wenn der Bahnlaufpfad der Bahn von der ersten zur zweiten Walze zwischen zwei Bändern verläuft. Die Bänder übernehmen dabei eine wärmeisolierende Funktion oder eine über das Querprofil temperaturausgleichende Funktion, je nachdem ob die Bänder aus Kunststoff oder Metall sind.It is advantageous if the web running path of the web runs from the first to the second roller between two belts. The bands take over a heat-insulating function or over the cross-profile temperature-compensating function, depending on whether the bands are made of plastic or metal.
Von ganz besonderem Vorteil ist es, wenn beide Walzen den geraden Verlauf wenigstens eines Bandes zwischen zwei Leitwalzen ablenken um zwei Behandlungszonen zu schaffen. Im Vergleich mit nur einer "eintauchenden" Walze wird die Anlage durch die überlappenden Bänder nur unwesentlich länger, aber man gewinnt eine zweite Behandlungszone, bei der unabhängig von der ersten ein Druck auf die Bahn eingestellt werden kann.Of particular advantage is when both rollers deflect the straight course of at least one band between two guide rollers to create two treatment zones. Compared with only one "plunging" roller, the overlapping belts make the system only insignificantly longer, but one gains a second treatment zone in which a pressure on the web can be set independently of the first one.
Mit Vorteil ist dafür gesorgt, dass die Ablenkung und somit der Umschlingungswinkel über Verstelleinrichtungen für wenigstens eine Walze einstellbar ist. Wie bereits erwähnt, können so die Drücke und die Länge der Behandlungszone variiert werden. Solche Walzenverstelleinrichtungen sind aus dem Kalanderbau hinreichend bekannt. In der Regel greifen Hydraulikzylinder unterhalb der Lager an, um die Walzenachse zu verschieben. Es ist aber auch bekannt, solche Verstellwege lediglich durch einen radial beweglichen Mantel, der um eine feststehende Achse dreht, zu realisieren.Advantageously, it is ensured that the deflection and thus the wrap angle is adjustable via adjusting devices for at least one roller. As already mentioned, the pressures and the length of the treatment zone can be varied. Such Walzenverstelleinrichtungen are known from the calender construction sufficiently. As a rule, hydraulic cylinders engage below the bearings to move the roller axis. However, it is also known to realize such adjustment paths only by a radially movable shell which rotates about a fixed axis.
Vorzugsweise nähern sich die Bänder in Richtung des Bahnlaufpfades vor der Behandlungszone einander an und bilden so einen trichterartigen Bahneinlaufabschnitt. Dies hat eine sehr einfache Bahnaufführung beispielsweise nach einem Bahnriss zur Folge.Preferably, the bands approach each other in the direction of the web travel path in front of the treatment zone and thus form a funnel-like web inlet section. This results in a very simple web presentation, for example after a web break.
Da eine Satinage oder Trocknung einer Papierbahn nie ohne Wärmeeinwirkung erfolgt, ist es von Vorteil, wenn wenigstens eine Walze und/oder alternativ wenigstens ein Band beheizbar ist. Beheizte Walzen sind im Papiermaschinenbau hinreichend bekannt. Das Band kann für den Fall, dass es ein Stahlband ist, einfach über eine induktive Außenheizung erfolgen, mit der die Temperatur zusätzlich über das Querprofil profilierbar sein kann. Bevorzugte Oberflächentemperaturen zur Behandlung einer Papierbahn liegen zwischen 40 und 300°C.Since a calendering or drying of a paper web never takes place without the action of heat, it is advantageous if at least one roller and / or alternatively at least one belt can be heated. Heated rolls are well known in papermaking. In the event that it is a steel strip, the strip can simply be made via an inductive external heating with which the temperature can additionally be profiled over the transverse profile. Preferred surface temperatures for the treatment of a paper web are between 40 and 300 ° C.
Um einen kurzen Druckimpuls innerhalb der Behandlungszone zu erreichen, kann es sinnvoll sein, wenn zwei Walzen unter Dazwischenschalten wenigstens eines Bandes und der Faserstoffbahn über Kraftgeber gegeneinander pressbar sind. Um die Verdichtung der Bahn zu vergleichmäßigen kann dafür gesorgt werden, dass die Oberfläche wenigstens einer Walze mit einem elastischen Belag versehen ist.In order to achieve a short pressure pulse within the treatment zone, it may be useful if two rollers with the interposition of at least one band and the fibrous web via force transmitters are pressed against each other. To even out the compaction of the web it can be ensured that the surface of at least one roller is provided with an elastic covering.
Bevorzugt weist in diesem Fall wenigstens eine Walze eine Einstellbarkeit in ihrer Biegung auf. Solche Walzen sind als Walzen mit hydrostatischen Stützelementen oder in Form von sogenannten S-Walzen ebenfalls bekannt. Der Einsatz solcher Walzen bietet den Vorteil, dass Profilprobleme beispielsweise im Bulk der zu behandelnden Bahn ausgeglichen werden können.Preferably, in this case, at least one roller has an adjustability in its bending. Such rolls are also known as rolls with hydrostatic support elements or in the form of so-called S-rolls. The use of such rolls offers the advantage that profile problems, for example in the bulk of the web to be treated, can be compensated.
