Description

Wickeleinrichtung und Verfahren zum Aufwickeln von bahnformigen Materialien  Winding device and method for winding web-form materials
Die Erfindung betrifft eine Wickeleinrichtung zum Aufwickeln von bahnformigen Materialien nach dem Oberbegriff des Patentanspruchs 1 und ein Verfahren zum Aufwickeln von bahnformigen Materialien nach dem Oberbegriff des Patentanspruchs 14. The invention relates to a winding device for winding web-form materials according to the preamble of patent claim 1 and a method for winding web-form materials according to the preamble of patent claim 14.
In der Produktion insbesondere von Folien wie etwa Kunststofffolien werden Folien als Endlosmaterial produziert und in Wickeleinrichtungen auf Wickelhülsen (Papphülsen, Kunststoffhülsen, Metallhülsen,...) zu Wickeln aufgewickelt. Je nach Art der Kunststoffmaterialien neigt die Folie während des Wickel prozesses mehr oder weniger dazu, so genannte Wickeldefekte auszubilden. Ein Wickeldefekt ist z. B. der Kantenaufbau. Bei diesem Defekt klappen die äußeren Kanten des Wickels während des Wickeins um, wodurch eine deutliche Durchmesservergrößerung der Folienrolle an den Rändern des Wickels erkennbar ist. Jedoch auch ein schlechter Schnitt bzw. eine stumpfe Klinge an einer Längsschneidstation können zu einem solchen Kantenaufbau führen; durch den schlechten Schnitt entsteht eine Dickstelle an der Folienkante. Durch das stetige Aufeinanderlegen dieser Folienkante entsteht eine deutliche Durchmesservergrößerung in den Randbereichen der Folienwickel, also ein Kantenaufbau. In the production of films, in particular, such as plastic films, films are produced as endless material and wound into winding devices on winding tubes (cardboard tubes, plastic sleeves, metal sleeves, etc.) to form windings. Depending on the nature of the plastic materials, the film tends more or less during the winding process to form so-called winding defects. A winding defect is z. B. the edge structure. During this defect, the outer edges of the roll fold over during the winding, whereby a significant increase in diameter of the film roll can be seen at the edges of the roll. However, even a bad cut or a blunt blade at a longitudinal cutting station can lead to such edge structure; the bad cut creates a thick spot on the foil edge. Due to the constant juxtaposition of this film edge creates a significant increase in diameter in the edge regions of the film roll, so an edge structure.
Ein Kantenaufbau führt in vielen Fällen dazu, dass die fertig produzierte Folienrolle nicht mehr abwickelbar ist. Sie reißt während des Abwickelvorgangs ständig, was beispielsweise eine automatische Verpackung von Gütern mit diesen Folienrollen unmöglich macht. Der Grund dafür ist, dass die Randbereiche der Folie wesentlich stärker beansprucht werden, so dass ein Einreißen sehr wahrscheinlich ist. An edge structure leads in many cases to the fact that the finished film roll is no longer unwound. It breaks during the unwinding process constantly, which makes, for example, an automatic packaging of goods impossible with these film rolls. The reason is that the Edge regions of the film are much more stressed, so that tearing is very likely.
Die Aufgabe der vorliegenden Erfindung ist es daher, eine Wickelvorrichtung und ein Verfahren vorzuschlagen, mit welchen ein solcher Kantenaufbau verringerbar oder sogar ganz vermeidbar ist. The object of the present invention is therefore to propose a winding device and a method with which such an edge structure can be reduced or even completely avoided.
Erfindungsgemäß wird diese Aufgabe durch sämtliche Merkmale des Anspruchs 1 gelöst. In den abhängigen Ansprüchen sind mögliche Ausgestaltungen der Erfindung angegeben. According to the invention this object is achieved by all features of claim 1. In the dependent claims, possible embodiments of the invention are given.
Gemäß der vorliegenden Erfindung ist vorgesehen, dass wenigstens eine Rolle vorgesehen ist, deren Oberfläche an den Rand des sich auf dem Wickel befindlichen, bahnformigen Materials mit einer Anstellkraft anstellbar ist. Unter „Rand" wird im Rahmen dieser Offenbarung verstanden, dass die Rolle sich nicht über die gesamte Breite des Wickels erstreckt, sondern höchstens bis zu einer Entfernung von 5 cm von der jeweiligen Stirnseite des Wickels. Jedoch ist es nicht notwendig, dass die gesamte Oberfläche der Rolle an dem Wickel anliegt. Vielmehr kann ein Teil der Oberfläche der Rolle nicht in Kontakt mit dem Wickel stehen. According to the present invention, it is provided that at least one roller is provided, the surface of which can be adjusted to the edge of the web-form material located on the reel with an adjusting force. By "edge" it is meant in the context of this disclosure that the roll does not extend over the entire width of the roll but at most up to a distance of 5 cm from the respective end face of the roll However, it is not necessary that the entire surface Rather, part of the surface of the roll may not be in contact with the roll.
Mit der Erfindung ist es nun möglich, dass die Ränder des bahnformigen Materials, welche bereits mittels der Kontaktwalze auf den Wickel gelegt wurden, angedrückt werden. Die Vermeidung des Kantenaufbaus kommt nun durch den folgenden Effekt zustande. Beim Wickeln wird in der Regel zwischen die Lagen des bahnformigen Materials eine gewisse Menge an Luft mit eingewickelt. Auch die Luftmenge hat einen Einfluss auf den Durchmesser des gesamten Wickels, also nicht nur die Dicke des bahnformigen Materials. Durch die Rolle an den Rändern des Wickels wird hier nun die Luft verdrängt, die nun entweder nach außen gelangt oder in Richtung der Wickelmitte gedrückt wird. Aufgrund der nun verringerten Luftmenge im Randbereich können die oben beschriebenen Wickeldefekte ausgeglichen werden, so dass der Kantenaufbau verringert wird. Eine erfindungsgemäß aufgewickelte Folie neigt beispielsweise nun nicht mehr zum Reißen, so dass eine Weiterverarbeitung zuverlässiger erfolgen kann. With the invention, it is now possible that the edges of the web-shaped material, which have already been placed on the winding by means of the contact roller, are pressed. The avoidance of edge building is now achieved through the following effect. When winding a certain amount of air is usually wrapped between the layers of web-shaped material with. Also, the amount of air has an influence on the diameter of the entire coil, not just the thickness of the web-shaped material. Due to the role at the edges of the coil here now the air is displaced, which now either comes to the outside or is pressed in the direction of the winding center. Due to the now reduced amount of air in the edge region, the winding defects described above can be compensated, so that the edge structure is reduced. For example, a film wound according to the invention tends no longer to tearing, so that further processing can be done more reliably.
Vorteilhaft ist es, wenn die wenigstens eine Rolle parallel zur Kontaktwalze verlagerbar ist. Damit kann die Position der Rolle an die Breite des Wickels angepasst werden, so dass die Erfindung auch bei Wickeln unterschiedlicher Breite einsetzbar ist. Ferner kann vorgesehen sein, dass eine variable Anzahl an Rollen einsetzbar ist. Damit ist es möglich, die Erfindung auch dann zu verwenden, wenn ein bahnförmiges Material vor dem Aufwickeln durch Längsschneiden zu mehreren Teilbahnen aufgeteilt wird, wobei diese Teilbahnen dann auf separate Hülsen zu unabhängigen Wickeln aufwickelbar sind. Oft befinden sich diese Hülsen jedoch auf derselben Wickelwelle. In diesem Fall ist es sogar möglich, dass eine Rolle an den Rändern von zwei zueinander benachbarten Wickeln anliegt. Damit kann einerseits die Menge an benötigten Rollen verringert werden und andererseits auch der Abstand der Wickel gering gehalten werden, ohne dass auf den Mindestabstand zweier Rollen Rücksicht genommen werden müsste. Eine einzelner Wickel wird in diesem Zusammenhang als„Nutzen" bezeichnet. In einer vorteilhaften Weiterbildung ist vorgesehen, dass die wenigstens eine Rolle drehbar in einer Lagervorrichtung gelagert ist, welche an unterschiedlichen Stellen einer Traverse positionierbar ist, wobei insbesondere sich die Traverse parallel zur Kontaktwalze erstreckt. Damit kann die Lagervorrichtung an unterschiedlichen Orten der Traverse angeordnet und auch befestigt werden, um die oben angesprochene Anpassung an unterschiedliche Breiten des Wickels bzw. auch an die Anzahl der Nutzen zu ermöglichen. Beispielsweise kann die Lagervorrichtung auf die Traverse aufgesetzt und mit dieser verschraubt oder an diese geklemmt werden. Bevorzugt ist jedoch, dass die Traverse als Schiene ausgebildet ist, auf welcher die Lagervorrichtung verschiebbar gelagert ist, was die Handhabung vereinfacht. Vorteilhaft ist es dabei, wenn die Lagervorrichtung als Schlitten ausgebildet ist. Eine Verschiebung erfolgt vorzugsweise händisch, eine motorische Verstellung ist allerdings ebenso denkbar. In einer weiteren Ausgestaltung der Erfindung, die ebenfalls vorteilhaft ist, ist die Rolle als eine langgestreckte Walze ausgebildet, welche zumindest eine in Umfangsrichtung umlaufende Erhöhung umfasst, deren Oberfläche an den Rand des sich auf dem Wickel befindlichen, bahnförmigen Materials anstellbar ist. Im Gegensatz zu den bereits beschriebenen, separaten Rollen ist hier somit eine Walze vorgesehen. Diese Walze trägt eine Erhöhung. Mit anderen Worten ist zumindest ein Ring auf der Walze angeordnet, welcher auf einen Rand des Wickels wirkt. Die Walze an sich tritt bevorzugt mit dem bahnförmigen Material nicht in Kontakt. Der Einsatz einer Walze kann im Vergleich zum Vorsehen einer Traverse eine höhere Biegesteifigkeit bringen, so dass insbesondere bei einer großen Anzahl an Nutzen die Anstellkraft über die Breite der Walze konstant ist. Um generell eine Durchbiegung zu kompensieren, kann es im Rahmen der Erfindung vorgesehen sein, dass die Rollen oder die Erhöhungen einen unterschiedlichen Durchmesser haben, die, je näher sie relativ zur Mitte der Kontaktwalze positioniert sind, beispielsweise größer sind, da dort die größte Durchbiegung zu erwarten ist. It is advantageous if the at least one roller is displaceable parallel to the contact roller. Thus, the position of the roller can be adapted to the width of the coil, so that the invention can also be used in coils of different widths. Furthermore, it can be provided that a variable number of rollers can be used. Thus, it is possible to use the invention even if a web-shaped material is divided by winding into several partial webs prior to winding, these partial webs are then wound on separate sleeves to independent windings. Often, however, these sleeves are on the same winding shaft. In this case, it is even possible that a roll is applied to the edges of two mutually adjacent coils. Thus, on the one hand, the amount of required roles can be reduced and on the other hand, the distance of the rolls are kept low, without having to take into account the minimum distance between two roles. A single winding is referred to in this context as "use." In an advantageous development, it is provided that the at least one roller is rotatably mounted in a bearing device, which can be positioned at different points of a traverse, wherein in particular the traverse extends parallel to the contact roller Thus, the bearing device can be arranged at different locations of the traverse and also be attached in order to allow the above-mentioned adaptation to different widths of the coil or to the number of uses.For example, the bearing device can be placed on the crossbar and screwed with this or However, it is preferred that the crossbeam is designed as a rail on which the bearing device is displaceably mounted, which simplifies handling, it is advantageous if the bearing device is designed as a carriage By hand, a motor adjustment is also conceivable. In a further embodiment of the invention, which is also advantageous, the roller is formed as an elongated roller, which comprises at least one circumferentially circumferential elevation, the surface of which can be adjusted to the edge of the web-shaped material located on the winding. In contrast to the separate rollers already described, a roller is thus provided here. This roller carries an increase. In other words, at least one ring is arranged on the roller, which acts on an edge of the coil. The roll itself preferably does not contact the sheet material. The use of a roller can bring about a higher bending stiffness in comparison with the provision of a crossbeam, so that the setting force across the width of the roller is constant, in particular for a large number of uses. In order to compensate for a deflection in general, it may be provided in the invention that the rollers or the elevations have a different diameter, the closer they are positioned relative to the center of the contact roller, for example, are larger, because there the greatest deflection to is expected.
In einer vorteilhaften Weiterbildung sind diese Erhöhungen entlang der Walze verschiebbar, so dass auf einfache Weise die Anpassung an die Nutzen- bzw. Wickelbreite möglich ist. In einer weiteren Ausführungsform ist vorgesehen, dass die zumindest eine Rolle durch einen Antrieb antreibbar ist. Damit ist es nicht notwendig, dass die Rolle durch den Wickel in Rotation versetzt wird. Gerade letzteres kann insbesondere bei empfindlichen Materialien zu Beschädigungen derselben führen. Vorteilhaft ist diese Ausführungsform in Kombination mit einer bereits beschriebenen, mit Erhöhungen versehenen Walze, da hier nur ein einzelner Antrieb notwendig ist. Bei separaten Rollen werden mehrere Antriebe und/oder Getriebeverbindungen benötigt, um alle Rollen mit einer Kraft zum Drehantreiben beaufschlagen zu können. Mit einem Antrieb kann die zumindest eine Rolle in Voreilung oder in Nacheilung angetrieben werden. Das bedeutet, dass die Umfangsgeschwindigkeit größer bzw. kleiner ist als die Umfangsgeschwindigkeit des Wickels. Damit kann die Luftverdrängung bei bestimmten Materialien verbessert werden. Vorteilhaft ist es, wenn die Rolle oder die Traverse an zwei Schwenkarmen angeordnet ist, welche um eine parallel zur Kontaktwalze verlaufenden Schwenkachse schwenkbar ist. Eine Anordung an Schwenkarmen ermöglicht eine einfach ausgeführte Anstellung der Rolle an einen Wickel mit einer Schwenklagerung, die etwas abseits der eigentlichen Wickelstelle angeordnet sein kann. In der Regel sind hier die Platzverhältnisse günstiger. In an advantageous development, these elevations are displaceable along the roller, so that adaptation to the useful or winding width is possible in a simple manner. In a further embodiment, it is provided that the at least one roller can be driven by a drive. Thus, it is not necessary that the roll is rotated by the winding. Especially the latter can lead to damage of sensitive materials in particular. This embodiment is advantageous in combination with an already described, provided with elevations roller, since only a single drive is necessary here. In separate roles, multiple drives and / or gear connections are required to act on all roles with a force for rotary drive can. With a drive, the at least one roller can be driven in advance or in lag. That means, the circumferential speed is greater or less than the peripheral speed of the reel. This can improve air displacement in certain materials. It is advantageous if the roller or the traverse is arranged on two pivot arms, which is pivotable about a pivot axis extending parallel to the contact roller. An arrangement of pivoting arms allows a simple running employment of the role of a winding with a pivot bearing, which may be located slightly away from the actual winding point. As a rule, the space here is cheaper.
Besonders vorteilhaft ist es dabei, wenn die Drehachse der Kontaktwalze und die Schwenkachse koaxial verlaufen. Damit ist gewährleistet, dass die Rolle stets - unabhängig vom Durchmesser des Wickels - in Kontakt mit dem Wickel treten kann und dass der konstruktive Auswand gering ist. It is particularly advantageous if the axis of rotation of the contact roller and the pivot axis are coaxial. This ensures that the roll can always - regardless of the diameter of the coil - come into contact with the winding and that the constructive Auswand is low.
In weiterer, vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass eine Kraftbereitstellungseinrichtung vorgesehen ist, mit welcher die Anstellkraft bereitstellbar ist und welche sich insbesondere an einem Maschinengestell abstützt. Alternativ dazu kann sich die Kraftbereitstellungseinrichtung an den Maschinenelementen abstützen, die auch die Kontaktwalze tragen. Dies ist insbesondere dann vorteilhaft, wenn die Kontaktwalze über die genannten Maschinenelemente relativ zum Maschinengestell bewegbar ist. Durch das Vorsehen einer Kraftbereitstellungseinrichtung kann die Rolle mit einer einstellbaren Anstellkraft an den Wickel angestellt werden. Diese Anstellkraft kann insbesondere in Abhängigkeit von dem bahnförmigen Material gewählt werden. In a further, advantageous embodiment of the invention, it is provided that a power supply device is provided with which the contact force can be provided and which is supported in particular on a machine frame. Alternatively, the power supply device can be supported on the machine elements, which also carry the contact roller. This is particularly advantageous if the contact roller is movable relative to the machine frame via said machine elements. By providing a power supply device, the roller can be made with an adjustable contact force to the winding. This contact force can be selected in particular depending on the web-shaped material.
Im Zusammenhang mit dem Vorsehen von Schwenkarmen ist es vorteilhaft, wenn die Kraftbereitstellungseinrichtung auf diese Schwenkarme wirkt. Dies führt zu einer einfachen Konstruktion und Bauausführung einer erfindungsgemäßen Wickeleinrichtung. In einer erfindungsgemäßen Wickeleinrichtung kann ferner eine Anstellkraftregelung vorgesehen sein. In diesem Fall ist eine Anstellkraftmesseinrichtung vorgesehen, mit welcher die tatsächliche Anstellkraft messbar ist. In einer Rechen- und Steuervorrichtung ist dann dieser von der Anstellkraftmesseinrichtung bereitgestellte Messwert mit einem Sollwert vergleichbar. Bei Abweichungen, die einen festgelegten Grenzwert überschreiten, gibt die Rechen- und Steuereinrichtung Steuersignale an die Kraftbereitstellungseinrichtung ab, aufgrund welcher die Anstellkraft veränderbar ist. Dabei kann vorgesehen sein, dass der Sollwert für die Anstellkraft in Abhängigkeit vom Material und/oder vom Wickeldurchmesser veränderbar ist. Beispielsweise kann die Anstellkraft bei größer werdendem Wickeldurchmesser vergrößert oder verringert werden, bevorzugt in stetiger Weise. Die Änderungen können dabei über den Wickeldurchmesser linear erfolgen. Jedoch ist auch eine nichtlineare Abhängigkeit denkbar. In connection with the provision of pivoting arms, it is advantageous if the power supply device acts on these pivot arms. This leads to a simple construction and construction of a winding device according to the invention. In a winding device according to the invention, a Anstellkraftregelung can also be provided. In this case, an Anstellkraftmesseinrichtung is provided with which the actual contact force can be measured. In a computing and control device, this measured value provided by the contact force measuring device is then comparable to a desired value. In the case of deviations which exceed a defined limit value, the arithmetic and control device emits control signals to the force supply device, on the basis of which the adjusting force can be changed. It can be provided that the desired value for the contact force in dependence on the material and / or the winding diameter is variable. For example, the contact force can be increased or decreased with increasing winding diameter, preferably in a continuous manner. The changes can be linear over the winding diameter. However, a nonlinear dependence is also conceivable.
Die oben genannte Aufgabe wird zusätzlich durch ein Verfahren mit den Merkmalen des Anspruchs 14 gelöst. Demnach zeichnet sich das erfindungsgemäße Verfahren dadurch aus, dass wenigstens eine Rolle mit seiner Oberfläche an den Rand des sich auf dem Wickel befindlichen, bahnförmigen Materials mit einer Anstellkraft angestellt wird. Damit werden die gleichen Vorteile erzielt, wie sie bereits weiter oben im Zusammenhang mit der erfindungsgemäßen Wickelvorrichtung beschrieben wurden. The above object is additionally achieved by a method having the features of claim 14. Accordingly, the method according to the invention is characterized in that at least one roller is set with its surface against the edge of the web-shaped material located on the winding with a setting force. Thus, the same advantages are achieved, as described above in connection with the winding device according to the invention.

Die Figur 1 zeigt eine erfindungsgemäße Wickelvorrichtung 100, wie sie vorzugsweise mit einer Blasfolienanlage oder einer Flachfolienanlage zur Herstellung von Kunststofffolie kombiniert wird. Das bahnförmige Material 101 , also vorzugsweise eine Kunststoffbahn, wird entlang einer Transportrichtung T auf eine Kontaktwalze 102, die in Richtung R-i rotiert, geführt. Im Kontaktpunkt 1 10 ist die Kontaktwalze an einen Wickel 103 angestellt (bzw. der Wickel 103 ist an die Kontaktwalze 102 angestellt). In diesem Kontaktpunkt 1 10 wird das bahnförmige Material 101 von der Kontaktwalze 102 auf den Wickel 103 geführt und dort angedrückt. Der Wickel 103 ist fest auf der Wickelwelle 104 gehalten, wobei die Wickelwelle 104 in Richtung R2 rotiert. FIG. 1 shows a winding device 100 according to the invention, as it is preferably combined with a blown film line or a flat film line for the production of plastic film. The web-shaped material 101, ie preferably a plastic web, is guided along a transport direction T onto a contact roller 102, which rotates in the direction Ri. In the contact point 1 10, the contact roller is employed on a winding 103 (or the winding 103 is made to the contact roller 102). In this contact point 1 10, the web-shaped material 101 is guided by the contact roller 102 on the winding 103 and pressed there. The winding 103 is held firmly on the winding shaft 104, wherein the winding shaft 104 rotates in the direction R 2 .
Eine Walze 120 ist drehbar gelagert, wobei die Walze Erhöhungen 121 trägt, die vorzugsweise ringförmig sind. Die Walze 120 kann auf einer Achse drehbar gelagert sein, vorzugsweise ist sie jedoch fest auf einer Welle 122 angeordnet, welche im Schwenkarm 123 drehbar gelagert ist. Der Schwenkarm 123 ist wiederum koaxial zur Rotationsachse der Kontaktwalze schwenkbar gelagert. Die Schwenklagerung 124 des Schwenkarms 123 kann jedoch unabhängig von der Drehlagerung der Kontaktwalze 102 vorgesehen sein. Die Kontaktwalze ist relativ zum nicht gezeigten Maschinengestell drehbar bzw. rotierbar. A roller 120 is rotatably supported, the roller carries elevations 121, which are preferably annular. The roller 120 may be rotatably mounted on an axis, but preferably it is fixedly mounted on a shaft 122 which is rotatably mounted in the pivot arm 123. The pivot arm 123 is in turn pivotally mounted coaxially with the axis of rotation of the contact roller. However, the pivot bearing 124 of the pivot arm 123 may be provided independently of the pivot bearing of the contact roller 102. The contact roller is rotatable or rotatable relative to the machine frame, not shown.
Zur Bereitstellung der Andrückkraft, die durch den Pfeil F symbolisiert ist, ist eine Kraftbereitstellungseinrichtung K vorgesehen, die beispielsweise mit einem Drehlager an dem Maschinengestell und mit einem weiteren Drehlager an dem Schwenkarm 123 angreift. Die Kraftbereitstellungseinrichtung kann durch eine druckluftbetriebene Kolbenzylindereinheit realisiert sein. Gleichfalls ist ein Hydraulikzylinder denkbar. Auch eine elektromotorisch betriebene Kraftbereitstellungseinrichtung ist grundsätzlich denkbar. To provide the pressing force, which is symbolized by the arrow F, a force providing device K is provided, for example, with a Pivot on the machine frame and with another pivot bearing on the pivot arm 123 attacks. The power supply device can be realized by a compressed-air-operated piston-cylinder unit. Likewise, a hydraulic cylinder is conceivable. An electric motor operated power supply device is conceivable in principle.
Die Figur 2 zeigt nun die Ansicht II - II aus der Figur 1 , wobei gleiche Bauteile mit gleichen Bezugszeichen versehen sind. In dieser Ansicht ist jedoch erkennbar, dass das bahnförmige Material aus drei Einzelbahnen 101 , 101 ' und 101 " besteht und damit auf separaten Wickeln 103, 105 und 106 aufgewickelt wird. Dennoch werden diese Einzelbahnen über die einzige Kontaktwalze 102 zugeführt. Zu erkennen ist ebenfalls, dass die Walze 120 insgesamt vier Erhöhungen 121 , 131 , 141 und 151 trägt, wobei die äußeren Erhöhungen 121 und 151 an jeweils einen Rand des Wickels 103 bzw. 106 angestellt sind. Die mittleren Erhöhungen 131 und 141 sind jedoch an den Rändern von jeweils zwei Wickeln angestellt. Die Erhöhung 131 ist somit an den Rändern der Wickel 103 und 105 angestellt, wogegen die Erhöhung 141 an den Rändern der Wickel 105 und 106 angestellt ist. Im Zusammenhang mit den Figuren 3 und 4 wird nun ein weiteres Ausführungsbeispiel der Erfindung erläutert. Hierbei ist eine Traverse 301 vorgesehen, die, um eine möglichst große Biegesteifigkeit zu gewährleisten, beispielsweise als Doppel-T-Träger ausgestaltet ist. Die Traverse 301 trägt eine Schiene 302, auf welcher Schlitten 303 verschiebbar gelagert sind. Diese Verschiebbarkeit ist durch die Doppelpfeile 304 angedeutet. Auf jeden Schlitten sind Tragstützen 305 aufgebaut, in welchen eine Rolle 306 drehbar gelagert ist. FIG. 2 now shows the view II-II from FIG. 1, wherein identical components are provided with the same reference numerals. In this view, however, it can be seen that the web-shaped material consists of three individual webs 101, 101 'and 101 "and is thus wound on separate reels 103, 105 and 106. Nevertheless, these individual webs are fed via the single contact roller 102. It can also be seen in that the roller 120 carries a total of four elevations 121, 131, 141 and 151, wherein the outer elevations 121 and 151 are respectively engaged with an edge of the reels 103 and 106. However, the middle elevations 131 and 141 are at the edges of, respectively The elevation 131 is thus set at the edges of the reels 103 and 105, whereas the elevation 141 is set at the edges of the reels 105 and 106. A further embodiment of the invention will now be explained in connection with FIGS In this case, a traverse 301 is provided which, in order to ensure the greatest possible flexural rigidity, for example as a double-T carrier Traverse 301 carries a rail 302 on which carriages 303 are displaceably mounted. This displaceability is indicated by the double arrows 304. On each carriage support posts 305 are constructed in which a roller 306 is rotatably mounted.
Betrachtet man nun die Figuren 1 und 2, so kann der Aufbau gemäß der Figuren 3 und 4 die Walze 120 mit den Erhöhungen 121 , 131 , 141 und 151 sowie die Welle ersetzen. Somit kann die Traverse 301 direkt an den Schwenkarmen 123 befestigt sein. Die Rollen 306 übernehmen dann die Funktion der Erhöhungen 121 , 131 , 141 und 151 , d. h., diese Rollen 306 sind an die Ränder der Wickel 103, 105 und 106 anstellbar, um den Kantenaufbau zu vermeiden. Insgesamt ist zu beachten, dass die Erhöhungen 121 , 131 , 141 und 151 sowie die Rollen 306 eine im Vergleich zu ihrem Durchmesser geringe Breite aufweisen. So kann das Verhältnis Durchmesser zu Breite mindestens 2 : 1 betragen, vorzugsweise jedoch 3 : 1 . Das bedeutet, dass die genannten Elemente scheibenartig ausgeführt sind. Der Übergang von der Umfangsfläche zu den Stirnseiten der Erhöhungen bzw. Rollen kann abgerundet sein, um Markierungen auf dem bahnförmigen Material, die bei einer eckigen Ausgestaltung entstehen können, zu vermeiden. Solche Markierungen stellen zumindest bei Kunststofffolien eine Beschädigung dar. Referring now to Figures 1 and 2, the structure according to Figures 3 and 4 can replace the roller 120 with the elevations 121, 131, 141 and 151 and the shaft. Thus, the traverse 301 may be attached directly to the pivot arms 123. The rollers 306 then take over the function of the elevations 121, 131, 141 and 151, ie, these rollers 306 can be adjusted to the edges of the reels 103, 105 and 106 in order to avoid the edge structure. Overall, it should be noted that the elevations 121, 131, 141 and 151 and the rollers 306 have a narrow width compared to their diameter. Thus, the ratio of diameter to width can be at least 2: 1, but preferably 3: 1. This means that the said elements are designed like a disk. The transition from the peripheral surface to the end faces of the elevations or rollers may be rounded in order to avoid markings on the web-like material, which may occur in a polygonal configuration. Such markings constitute damage, at least in the case of plastic films.
