Abstract

The roll (2) is esp. for paper and is supported at the underside to counteract sagging. A cushion of compressed air is generated between the support (5,6) and the roll. The support comprises one or more plates, whose surface largely matches the contour of the underside of the roll. The plate contains one or more compressed-air outlets (7), and the air can escape between it and the roll. The plate adjusts automatically in the radial direction of the roll dependent on the diameter of the latter, to match its contour. The plate can bend elastically under the action of an adjusting motor (6) with a hinge joint (8) to one of its lengthwise edges.

Description

Die Erfindung bezieht sich auf eine Wickelvorrichtung mit einer Wickelrolle für bahnförmiges Material, insbesondere Papier, und einer einer Durchbiegung der Wickelrolle von unten berührunglos entgegenwirkenden Stützeinrichtung, die ein Druckluftkissen zwischen der Stützeinrichtung und der Wickelrolle erzeugt, wobei die Stützeinrichtung wenigstens eine Stützplatte mit einer der Kontur der Unterseite der Wickelrolle weitgehend angepaßten Oberseite aufweist, in der wenigstens eine Druckluftaustrittsöffnung ausgebildet ist, wobei die Druckluft durch einen Spalt zwischen der Wickelrolle und der Stützplatte austreten kann und wobei die wirksame Flache der Stützplatte radial zur Wickelrolle in Abhängigkeit vom Wickeldurchmesser verstellbar ist und dabei der Wickelrollenkontur weitgehend angepaßt bleibt.The invention relates to a winding device with a winding roll for sheet material, in particular Paper, and one of a deflection of the Supporting device counteracting from below without contact, which a compressed air cushion between the support device and the winding roll, wherein the support device at least one support plate with one of the Contour of the underside of the winding roll largely adapted Has top, in which at least one Compressed air outlet opening is formed, the Compressed air through a gap between the winding roll and the support plate can emerge and the effective Flat of the support plate radially to the winding roll in Depending on the winding diameter is adjustable and largely adapted to the winding roll contour remains.

Beim Auf- und Abwickeln eines bahnförmigen Materials, insbesondere Papier, kommt es je nach Relation der Wickelmasse, Bahnbreite, physikalischen Eigenschaften der Wickellagen (z.B. Wickelhärte, Dehnungs-, Kompressions- und Reibverhalten des Papiers), Steifigkeit und Lagerabstand der Wickelwelle bzw. des Tambours zu Schwierigkeiten aufgrund der Durchbiegung der Aufwickelrolle.When winding and unwinding a sheet material, especially paper, it depends on the relation of the Winding mass, web width, physical properties the winding layers (e.g. winding hardness, elongation, compression and friction behavior of the paper), rigidity and Bearing distance of the winding shaft or the reel Difficulty due to the deflection of the take-up roll.

Vor allem bei Verwendung einer Kontakt- oder Anlagewalze, die etwa horizontal gegen die Wicklung auf der Wickelrolle gedrückt wird, führen unterschiedliche Durchbiegungen von Anlagewalze und Wickelrolle zu einem ungleichförmigen Kontaktdruckverlauf über die Bahnbreite, mit der Folge, daß Kreppfalten und Platzer in den Randbereichen der Wicklung auftreten.Especially when using a contact or contact roller, which is roughly horizontal against the winding on the Winding roller is pressed, perform different Deflections of the contact roller and winding roller into one non-uniform contact pressure curve across the web width, with the result that crepe folds and bursts in the Edge areas of the winding occur.

Aus der DE-OS 36 39 244 ist es bekannt, eine Durchbiegungsdifferenz durch vollständiges oder teilweises Aufheben des Rollengewichts über mitlaufende, unterstützende Bänder auszugleichen.From DE-OS 36 39 244 it is known to have a deflection difference by complete or partial cancellation the roll weight over moving, supportive Compensate bands.

Bei der aus der DE-OS 40 26 597 bekannten Wickelvorrichtung wird in einem Raum zwischen unterhalb der Wickelrolle und achsparallel zu dieser angeordneten Tragwalzen ein Überdruck erzeugt, der ein Luftkissen in einem Spalt zwischen der Wickelrolle und den Tragwalzen ausbildet.In the winding device known from DE-OS 40 26 597 is in a space between below the winding roll and axially parallel to this arranged support rollers creates an overpressure that creates an air cushion a gap between the winding roller and the support rollers trains.

Beide Vorrichtungen bewirken jedoch eine unzureichende Schonung der Wickeloberfläche, denn sowohl die Tragwalzen als auch das mitlaufende Band üben einen mechanischen Einfluß auf die aufzuwickelnde Bahn aus, und zwar bei der Wickelvorrichtung mit Luftkissenraum deshalb, weil die Abdichtung an den beiden axialen Enden des Luftkissenraums wegen des sich verändernden Wickelradius, der beispielsweise von 500 mm auf 3000 mm anwachsen kann, schwierig ist.However, both devices cause an insufficient Protection of the winding surface, because both the support rollers as well as the moving belt practice a mechanical Influence on the web to be wound up, namely in the case of the winding device with air cushion space, because the seal on the two axial ends of the Air cushion space due to the changing winding radius, which, for example, grow from 500 mm to 3000 mm can, is difficult.

Aus der DE 42 01 815 A1, Fig. 7, ist es bekannt, unterhalb der Wickelrolle einen sich über deren Länge erstreckenden, nach oben offenen und mit Druckluft beaufschlagten Luftkasten höhenverstellbar und verschwenkbar anzuordnen. An seinen stirnseitigen Oberkanten ist der Luftkasten mit der Krümmung der Wickelrolle mittels im Luftkasten angeordneter Stellelemente anpaßbaren Dichtleisten und an seiner einen längsseitigen Oberkante ebenfalls mit einer Dichtleiste und an der anderen längsseitigen Oberkante mit einer sich längs dieser Oberkante erstreckenden Distanzrolle versehen. Die Dichtleisten werden durch die sich beim Anschwenken des Luftkastens an die Wickelrolle an diese anlegende Distanzrolle in einem Abstand entsprechend einem gewünschten Luftspalt von der Wickelrolle gehalten, um eine Reibung zwischen der Wickelrolle und den Dichtleisten zu vermeiden. Bei der Ausführungsform nach Fig. 8 ist eine weitere Distanzrolle längs der anderen längsseitigen Oberkante des Luftkastens gelagert. Eine solche Einrichtung ist wegen ihrer zahlreichen Bauteile aufwendig und arbeitet nicht berührungslos.From DE 42 01 815 A1, Fig. 7, it is known below the winding roll has a length that extends over its length, open at the top and pressurized with compressed air Air box height adjustable and swiveling to arrange. On its front upper edges is the Air box with the curvature of the winding roll by means of Air box arranged adjusting elements adaptable sealing strips and on one longitudinal upper edge also with a sealing strip and on the other longitudinal top edge with a along this Provide upper edge extending spacer roller. The Sealing strips are by the when swiveling the Air box on the winding roll on this abutting spacer roll at a distance corresponding to a desired one Air gap held by the winding roll to a friction between the winding roller and the sealing strips to avoid. 8 is another spacer roll along the other long side Upper edge of the air box stored. Such Furnishing is because of its numerous components complex and does not work without contact.

Eine gattungsgemäße Wickelvorrichtung ist aus der DE-A-32 25 872 oder der US-A-3 920 136 bekannt, die dem Oberbegriff des Anspruchs 1 entspricht.A generic winding device is from DE-A-32 25 872 or US-A-3 920 136 known to the preamble of claim 1 corresponds.

Bei beiden bekannten Wickelvorrichtungen ist die Höhenlage der Drehachse der Wickelrolle in Abhängigkeit vom Wickelrollen-Durchmesser zwar unterschiedlich dargestellt, aber keine höhenverstellbare Lager- und Antriebseinrichtung offenbart. Wenn die Drehachse nicht höhenverstellbar gelagert ist, muß der Druck des Druckluftkissens bei dementsprechend frei schwebender Anordnung der Wickelrolle von vornherein dem größten Gewicht der Wickelrolle entsprechend dem größten Wickelrollendurchmesser entsprechen, wenn er nicht entsprechend dem Wickelrollendurchmesser geregelt ist, was ebenfalls nicht offenbart ist. Hierzu ist eine erhebliche Energie zur Erzeugung der Druckluft erforderlich, während gleichzeitig bei geringem Wickelrollendurchmesser und dementsprechend niedrigem Wickelrollengewicht und größerem Luftspalt übermäßig viel Druckluft ungenutzt entweicht.In both known winding devices, the altitude is the axis of rotation of the winding roll depending on Although the winding roll diameter is shown differently, but no height-adjustable storage and drive device disclosed. If the axis of rotation is not is adjustable in height, the pressure of the compressed air cushion accordingly free floating arrangement the winding roll from the outset the greatest weight the winding roll corresponding to the largest winding roll diameter match if he doesn't match that Winding roll diameter is regulated, which is also is not disclosed. This requires considerable energy required to generate the compressed air while at the same time with a small winding roll diameter and correspondingly low winding roll weight and larger Air gap Excessive compressed air escapes unused.

Bei der Wickelvorrichtung nach der DE-A-32 25 872 sind ferner in den Druckluftaustrittsöffnungen Rückschlagventile angeordnet, die unter Federdruck stehende Verschlußkugeln aufweisen. Diese Verschlußkugeln werden durch die Wickelrolle, soweit sie die Verschlußkugeln überdeckt, in die Offenstellung gedrückt. Dabei liegen die Verschlußkugeln jedoch unter dem Federdruck an der Wickelrolle an. Dies ergibt unerwünschte Drucklinien im Wickelrollenmaterial, insbesondere bei Papier oder einem anderen druckempfindlichen Material. Die Stützplatte besteht aus einem biegsamen Stahlband, das mit Kunststoff beschichtet ist und nur in der Mitte zwischen zwei Tragwalzen gehoben oder gesenkt werden kann, indem eine der beide Tragwalzen, um die die Längsabschnitte des Stahlbandes teilweise herumgewickelt sind, mittels eines Zylinders entsprechend verdreht wird. Eine selbsttätige Verstellung in Abhängigkeit vom Wickelrollendurchmesser ist hierbei nicht angesprochen.In the winding device according to DE-A-32 25 872 also check valves in the compressed air outlet openings arranged, the spring balls under spring pressure exhibit. These locking balls are through the winding roller, as far as it the locking balls covered, pressed into the open position. Lying there the locking balls, however, under the spring pressure on the Winding roll. This results in unwanted print lines in the Wrapping roll material, especially paper or one other pressure sensitive material. The support plate consists of a flexible steel band, which with Plastic is coated and only in the middle can be raised or lowered between two carrying rollers can by placing one of the two support rollers around which the Longitudinal sections of the steel strip partially wrapped around are rotated accordingly by means of a cylinder becomes. An automatic adjustment depending the roll diameter is not mentioned here.

Auch bei der Wickelvorrichtung nach der US-A-3 920 136 ist die Wickelrolle schwebend auf dem Druckluftkissen gelagert und die Stützplatte nicht selbsttätig in Abhängigkeit vom Wickeldurchmesser verstellbar. Auch hier ist mithin ein dem maximalen Gewicht der Wickelrolle entsprechender Luftdruck mit entsprechend hohen Druckluftverlusten erforderlich, insbesondere wenn die Stützplatte unter den Stirnkanten der Wickelrolle jeweils eine teilweise umlaufende Erhebung aufweist, die sich jedoch nicht in Längsrichtung der Wickelrolle erstreckt, so daß die Druckluft in Umfangsrichtung der Wickelrolle durch einen verhältnismäßig großen Luftspalt entweichen kann, dagegen die rotierende Wickelrolle bis zur Ausbildung des hohen Luftdrucks auf den Erhebungen reibend aufliegt.Also in the winding device according to US-A-3 920 136 the winding roll is floating on the compressed air cushion stored and the support plate not automatically dependent adjustable from the winding diameter. Here too is therefore the maximum weight of the winding roll corresponding air pressure with correspondingly high compressed air losses required, especially if the Support plate under the front edges of the winding roll in each case has a partially circulating survey that does not, however, extend in the longitudinal direction of the winding roll, so that the compressed air in the circumferential direction of the Winding roll through a relatively large air gap can escape, however, the rotating winding roller until the formation of high air pressure on the Surveys are frictionless.

Der Erfindung liegt die Aufgabe zugrunde, eine Wickelvorrichtung der gattungsgemäßen Art anzugeben, die eine die Bahn zuverlässiger schonende Abstützung der Wickelrolle innerhalb der Bahnbreite mit geringeren Druckluftverlusten ermöglicht.The invention has for its object a winding device of the generic type to specify the the web more reliable gentle support of the winding roll within the web width with less compressed air losses enables.

Erfindungsgemäß ist die Aufgabe dadurch gelöst, daß die Wickelrolle auf einer ortsfesten Drehachse angetrieben und die gesamte Stützplatte radial zur Wickelrolle in Abhängigkeit vom Wickeldurchmesser selbsttätig verstellt wird.According to the invention the object is achieved in that the Winding roller driven on a fixed axis of rotation and the entire support plate radially to the winding roll in Automatically adjusted depending on the winding diameter becomes.

Bei dieser Ausbildung wird ein Teil des Gewichts der Wickelrolle durch ihre ortsfeste Drehlagerung aufgenommen. Die Druckverluste und die für die Ausbildung des Druckluftkissens erforderliche Energie können daher geringer gehalten werden. Ferner werden die Druckluftverluste durch die selbsttätig in Abhängigkeit vom Wickeldurchmesser erfolgende Verschiebung der gesamten Stützplatte noch weiter verringert, da auf diese Weise, trotz der ortsfesten Lagerung der Drehachse der Wickelrolle, stets ein minimaler Luftspalt zwischen Stützplatte und Wickelrolle eingehalten werden kann. Eine Reibung zwischen Wickelrolle und Stützplatte wird von Anfang an völlig vermieden.With this training, part of the weight of the Winding roll taken up by its fixed pivot bearing. The pressure drops and those for the training of the Air cushion can therefore require energy be kept lower. Furthermore, the compressed air losses through the automatically depending on the Coil diameter shift of the entire Support plate further reduced because in this way, despite the fixed mounting of the axis of rotation of the winding roll, always a minimal air gap between the support plate and winding roll can be observed. A Friction between winding roller and support plate is caused by Avoided from the start.

Die Stützplatte kann biegeelastisch ausgebildet sein. Die Stützplatte kann sich daher über einen verhältnismäßig großen Umschlingungswinkel der Wickelrolle erstrecken und sich dennoch leicht unter der Kraft von Stellmotoren, die in der Nähe ihrer sich achsparallel zur Wickelrolle erstreckenden Ränder angreifen, gegen die Kraft der Druckluft so verbiegen, daß der Krümmungsradius ihrer Oberseite weitgehend dem jeweiligen Krümmungsradius des Wickels bzw. der Wicklung auf der Wickelrolle angepaßt ist.The support plate can be designed to be flexible. The support plate can therefore be proportionate extend large wrap angle of the winding roll and yet easily under the power of Servomotors that are near their axially parallel attack edges extending to the winding roll, against bend the force of the compressed air so that the radius of curvature their top largely the respective Radius of curvature of the winding or winding on the Winding roll is adjusted.

Es ist aber auch möglich, daß die Stützplatte an ihrer Unterseite in der Nähe jedes ihrer axialen Längsränder jeweils einen nach unten vorstehenden Vorsprung aufweist und zwischen den Enden der Vorsprünge ein Stellmotor gelenkig befestigt ist, durch den auf jene Enden eine Kraft ausübbar ist, die eine derartige Verbiegung der Stützplatte bewirkt, daß der Krümmungsradius ihrer Oberseite dem augenblicklichen Radius des Wickels auf der Wickelrolle entspricht.But it is also possible that the support plate on her Underside near each of its axial longitudinal edges each has a downwardly projecting projection and an actuator between the ends of the protrusions is articulated through which on those ends a force can be exerted that such a bending the support plate causes the radius of curvature of their Top of the current radius of the wrap corresponds to the winding roll.

Bei einer herkömmlichen Wickelvorrichtung nach Fig. 1 wird eine Bahn 1, hier eine Papierbahn, auf eine ortsfeste, angetriebene Wickelrolle 2 gewickelt und dabei durch eine Kontakt- oder Anlagewalze 3 horizontal mit einer Kraft Fk an die Wickelrolle 2 bzw. den Wickel 4 (oder die Wicklung) angedrückt. Mit zunehmendem Durchmesser und entsprechend steigendem Gewicht des Wickels 4 biegen sich die Wickelrolle 2 und der Wickel 4 stärker durch, wobei die unterschiedlichen Durchbiegungsdifferenzen ΔF zwischen Anlagewalze 3 und Wickelrolle 2 bzw. Wickel 4 zu einem ungleichförmigen Kontaktdruckverlauf qk über die Bahnbreite führen, mit der Folge, daß Kreppfalten und Platzer in den Randbereichen des Wickels 4 auftreten.In a conventional winding device according to FIG. 1, a web 1, here a paper web, is wound on a stationary, driven winding roll 2 and thereby horizontally by a contact or contact roll 3 with a force F k on the winding roll 2 or the winding 4 ( or the winding). With increasing diameter and correspondingly increasing weight of the winding 4, the winding roller 2 and the winding 4 bend more, the different deflection differences ΔF between the contact roller 3 and the winding roller 2 or winding 4 leading to an uneven contact pressure curve q k over the web width with which Consequence that crepe folds and bursts occur in the edge areas of the winding 4.

Bei dem Ausführungsbeispiel einer erfindungsgemäßen Wickelvorrichtung nach Fig. 2 ist eine Stützeinrichtung mit einer biegeelastischen Stützplatte 5 und pneumatischen oder hydraulischen Stellmotoren 6 in Form von Kolben-Zylinder-Anordnungen vorgesehen. Die Stützplatte 5 hat eine der Kontur der Unterseite der Wickelrolle 2 weitgehend angepaßte Oberseite, in der drei Druckluftaustrittsöffnungen 7, denen Druckluft durch die Stützplatte 5 hindurch aus einer nicht dargestellten Druckluftquelle zugeführt wird, ausgebildet sind. Die Druckluft kann durch Spalte 8 zwischen der Wickelrolle 2 und der Stützplatte 5 austreten und wirkt der in der Nähe der zur Wickelrolle 2 parallelen Längsränder der Stützplatte 5 angreifenden Kraft Fr der Stellmotoren 6 entgegen. Die Druckluft bildet ein Luftkissen in dem Spalt 8 zwischen der Stützplatte 5 und der Wickelrolle 2, wobei sich die Oberseite der Stützplatte 5 aufgrund der Biegeelastizität der Stützplatte 5 der Kontur des Wickels 4 mit zunehmendem Durchmesser des Wickels 4 von dem kleinsten Wickelradius Rmin, der dem Radius der Wickelrolle 2 entspricht, bis zum größten Krümmungsradius Rmax des Wickels 4 weitgehend anpaßt. Synchron mit der Zunahme des Durchmessers des Wickels 4 wird dazu die Stützplatte 5 durch die Stellmotoren 6 nach unten verschoben, wie es durch die untere Lage der Stützplatte 5 in Fig. 2 dargestellt ist.In the embodiment of a winding device according to the invention according to FIG. 2, a support device with a flexible support plate 5 and pneumatic or hydraulic servomotors 6 in the form of piston-cylinder arrangements is provided. The support plate 5 has a top surface largely adapted to the contour of the underside of the winding roll 2, in which three compressed air outlet openings 7, to which compressed air is supplied through the support plate 5 from a compressed air source, not shown, are formed. The compressed air can escape through gaps 8 between the winding roller 2 and the support plate 5 and counteracts the force F r of the servomotors 6 acting in the vicinity of the longitudinal edges of the support plate 5 parallel to the winding roller 2. The compressed air forms an air cushion in the gap 8 between the support plate 5 and the winding roll 2, the top of the support plate 5, due to the bending elasticity of the support plate 5, the contour of the winding 4 with increasing diameter of the winding 4 from the smallest winding radius R min corresponds to the radius of the winding roll 2, largely adapts to the largest radius of curvature R max of the winding 4. To this end, the support plate 5 is shifted downwards by the servomotors 6 in synchronism with the increase in the diameter of the winding 4, as is shown by the lower position of the support plate 5 in FIG. 2.

Bei dem Ausführungsbeispiel der erfindungsgemäßen Wickelvorrichtung nach Fig. 3 sind nur zwei Stützplatten 5 mit jeweils einer Druckluftaustrittsöffnung 7 vorgesehen, bei denen der Krümmungsradius der Oberseiten der Stützplatten 5 einem mittleren Krümmungsradius Rmittel des Wickels 4 angepaßt ist. Jede Stützplatte 5 hat nur eine Druckluftaustrittsöffnung 7 und wird individuell durch einen der beiden Stellmotoren 6 mit der Kraft Fr beaufschlagt, wobei die Wirkungsrichtung der Kräfte Fr, im Gegensatz zu der der Kräfte Fr bei dem Ausführungsbeispiel nach Fig. 2, in der Mitte der jeweiligen Stützplatte 5 angreift und genau radial zur Mittelachse der Wickelrolle 2 gerichtet ist.In the embodiment of the winding apparatus of the invention according to FIG. 3, only two support plates 5, each with a compressed air outlet opening 7 provided in which the radius of curvature of the tops of the support plates 5 a mean radius of curvature R medium of the reel 4 is adjusted. Each support plate 5 has only one compressed air outlet opening 7 and is subjected to the force F r individually by one of the two servomotors 6, the direction of action of the forces F r , in contrast to that of the forces F r in the embodiment according to FIG. 2, in the Attacks the center of the respective support plate 5 and is directed exactly radially to the central axis of the winding roll 2.

Bei beiden Ausführungsbeispielen sind die Stellmotoren 6 einerseits mit ihrer Kolbenstange an der Stützplatte 5 und andererseits an einem ortsfesten Gestell angelenkt. Ferner wirkt der Wickelradius als Führungsgröße für die Verstellung der Stützplatte(n) 5 durch die Stellmotoren 6 in einer Lageregeleinrichtung.In both embodiments, the servomotors 6 on the one hand with its piston rod on the support plate 5 and articulated on the other hand on a stationary frame. The winding radius also acts as a reference variable for the adjustment of the support plate (s) 5 by the Servomotors 6 in a position control device.

Bei beiden Ausführungsbeispielen können allerdings auch leichte Abweichungen von einem bei jedem Wickelradius genau konzentrischen Spalt 8 auftreten.In both embodiments, however, can also slight deviations from one with each winding radius exactly concentric gap 8 occur.

Während sich die Stützplatte 5 bei dem Ausführungsbeispiel nach Fig. 2 eventuell nicht ganz genau kreisförmig biegen läßt, ergeben sich bei dem Ausführungsbeispiel nach Fig. 3 Änderungen der Spalte 8 in Abhängigkeit vom Wickelradius, wie es in den Fig. 4 und 5 dargestellt ist: Bei dem kleinsten Wickelradius Rmin nach Fig. 4 hat der Spalt 8 die kleinste Höhe hmin in der Mitte und die größte Höhe hmax an den Längsrändern. Bei dem größten Wickelradius Rmax nach Fig. 5 hat der Spalt 8 dagegen die größte Höhe hmax in der Mitte und die kleinste Höhe hmin an den Rändern. Die Spalthöhe oder -weite ändert sich mithin um den Betrag h = hmax-hmin , da die Stützplatte 5 bei dem Ausführungsbeispiel nach den Fig. 3 bis 5 nicht biegeelastisch ist und nicht an beiden Längsrändern abgestützt wird.While the support plate 5 in the exemplary embodiment according to FIG. 2 may not be able to be bent exactly circularly, in the exemplary embodiment according to FIG. 3 there are changes in column 8 as a function of the winding radius, as shown in FIGS. 4 and 5: With the smallest winding radius R min according to FIG. 4, the gap 8 has the smallest height h min in the middle and the largest height h max at the longitudinal edges. In contrast, with the largest winding radius R max according to FIG. 5, the gap 8 has the greatest height h max in the middle and the smallest height h min at the edges. The gap height or width therefore changes by the amount h = h Max -H min , since the support plate 5 in the embodiment of FIGS. 3 to 5 is not flexible and is not supported on both longitudinal edges.

Es ist jedoch möglich, sowohl bei nur einer Stützplatte 5 gemäß Fig. 2 als auch bei zwei Stützplatten 5 gemäß Fig. 3, eine Abwandlung gemäß Fig. 6 vorzusehen, bei der die einzige oder jede Stützplatte 5 an ihrer Unterseite in der Nähe jedes ihrer axialen Längsränder jeweils einen nach unten vorstehenden Vorsprung 9 aufweist und zwischen den Enden der Vorsprünge 9 ein Stellmotor 10 gelenkig befestigt ist, durch den auf jene Enden eine tangentiale Kraft Ft ausübbar ist, die eine derartige Verbiegung der Stützplatte 5 bewirkt, daß der Krümmungsradius ihrer Oberseite dem augenblicklichen Radius R des Wickels 4 auf der Wickelrolle 2 entspricht. Auch kann hier für die bzw. jede Stützplatte 5 nur ein Stellmotor 6 vorgesehen sein, dessen radiale Kraft Fr in der Mitte der Stützplatte 5 angreift, während durch die tangentiale Kraft Ft des Linear-Stellmotors 10 ein Biegemoment M = Ft·a, wobei a der Hebelarm bzw. etwa die radiale Länge der Vorsprünge 9 ist, auf die Stützplatte 5 ausgeübt wird, das selbsttätig etwa umgekehrt proportional zum Wickelradius R eingestellt wird und eine kreisbogenförmige Verbiegung der Stützplatte 5 bewirkt. Auf diese Weise ist es möglich, den Spalt 8 bei allen Wickelradien R konzentrisch zur Achse der Wickelrolle 2 einzustellen und somit eine wesentliche Verringerung der mittleren Spalthöhe zu erreichen. Dies hat den Vorteil, daß der Luftverbrauch minimiert wird.However, it is possible to provide a modification according to FIG. 6 in which only one support plate 5 according to FIG. 2 and two support plates 5 according to FIG. 3, in which the single or each support plate 5 on its underside in the vicinity of each of them Axial longitudinal edges each have a downwardly projecting projection 9 and a servomotor 10 is articulated between the ends of the projections 9, by which a tangential force F t can be exerted on those ends, which causes such a bending of the support plate 5 that the radius of curvature of their Top corresponds to the current radius R of the winding 4 on the winding roll 2. Here too, only one servo motor 6 can be provided for the or each support plate 5, the radial force F r of which acts in the center of the support plate 5, while a bending moment is caused by the tangential force F t of the linear servomotor 10 M = F t · A , where a is the lever arm or approximately the radial length of the projections 9, is exerted on the support plate 5, which is automatically set approximately inversely proportional to the winding radius R and causes an arcuate bending of the support plate 5. In this way it is possible to set the gap 8 concentrically to the axis of the winding roll 2 for all winding radii R and thus to achieve a substantial reduction in the average gap height. This has the advantage that the air consumption is minimized.

Sodann ergibt sich bei der Wickelvorrichtung nach Fig. 6 eine klare Trennung zwischen der Stützkraftregelung und der Spaltformregelung, wobei der Wickelradius R die Führungsgröße für beide Regelvorgänge ist.Then in the winding device according to FIG. 6 a clear separation between the support force control and the gap shape control, the winding radius R the Reference variable for both control processes is.
