Abstract

A filling material includes a web of sheet made of metal, in particular aluminum, or of dimensionally stable flexible material, especially plastic, with the sheet being perforated with evenly spaced slits extending parallel in longitudinal direction of the band and stretched transversely to the longitudinal extension, and with the sheet profiled transversely to the longitudinal extension.

Description

Die Erfindung bezieht sich auf ein Füllmaterial, bei welchem ein Folienmaterial aus Metall, insbesondere Aluminium, oder aus formbeständigem, flexiblem Material, insbesondere Kunststoff, mit gleichmäßig verteilten, parallelen in Bandlängsrichtung verlaufenden Schlitzen perforiert und quer zur Bandlängsrichtung gestreckt ist.The invention relates to a filling material in which a film material made of metal, in particular aluminum, or of dimensionally stable, flexible material, especially plastic, with evenly distributed, parallel in the longitudinal direction of the strip running slots is perforated and stretched transversely to the tape longitudinal direction.

Derartige Materialien werden u.a. zur Füllung von Behältern für brennbares Fluid verwendet, da aufgrund der raschen Wärmeableitung eine explosionsartige Verbrennung der Flüssigkeiten verhindert wird.Such materials are among others for filling flammable fluid containers used because of the rapid heat dissipation an explosive Burning of liquids is prevented.

Es sind bereits derartige gestreckte Folien bekannt, bei welchen die in Längsrichtung der Folienbahn verlaufenden Schnitte in eine ebene Folienbahn eingebracht werden, die dann in dieser ebenen Form entsprechend quer zur Längserstreckung gestreckt wird, wodurch nur eine geringfügige Verformung aus der Bandebene heraus erfolgt. Es hat sich nun gezeigt, daß aufgrund der geringen Verformung aus der Bandebene heraus, die einzelnen Lagen der Folien in den Behältern zusammenbacken bzw. durch die Bewegung ineinandergreifen können, wodurch innerhalb des Behälters freie Räume entstehen können, in welchen dann die brennbare Flüssigkeit ohne die entsprechenden Folieneinlagen vorhanden ist und damit ein explosionsartiges Verbrennen wieder stattfinden kann.Such stretched films are already known, in which the in Cuts in the longitudinal direction of the film web into a flat film web are introduced, which are then in this flat shape accordingly across Is stretched longitudinally, whereby only a slight deformation from the Band level is done. It has now been shown that due to the low Deformation from the band level, the individual layers of the foils in the Bake containers together or interlock through the movement whereby free spaces can arise within the container, in which then the flammable liquid is present without the appropriate film inserts and thus an explosive burning can take place again.

In EP-A-0 377 397 ist eine mit in Längsrichtung verlaufenden Schlitzen versehene Bahn als Stand der Technik beschrieben, wobei gemäß dieser Druckschrift bevorzugt eine Bahn mit quer zur Längsrichtung verlaufenden Schlitzen vorgesehen ist, um Abdeckbahnen für eine Brandbekämpfung u.dgl. zu erreichen.In EP-A-0 377 397 there is one with longitudinally extending slots provided web described as prior art, wherein according to this document preferably a path is provided with slots running transversely to the longitudinal direction is to cover sheets for fire fighting and the like. to reach.

WO-A-98/09747 beschreibt das Stanzen und Prägen von Materialbahnen aus stärkeren formbeständigem Material, um Elemente zu schaffen, die als Zwischenelemente für Batterien, Brennstoffelementenblöcke u.dgl. eingesetzt werden können.WO-A-98/09747 describes the punching and embossing of material webs stronger dimensionally stable material to create elements that Intermediate elements for batteries, fuel element blocks and the like. be used can.

Der Erfindung liegt die Aufgabe zugrunde, eine Folie der eingangs genannten Art so zu verbessern, daß die angeführten Nachteile vermieden sind. Dies wird erfindungsgemäß dadurch erreicht, daß das Folienband mittels sich quer über die gesamte Folienbreite erstreckender Wellen quer zur Bandlängsrichtung und zur Folienoberfläche profiliert ist. Diese Querprofilierung bleibt während des Streckens erhalten, sodaß die aus der Bandebene heraus erfolgende Verformung während des Verstreckens sich zusätzlich zu der Profilierung ergibt, was einerseits eine höhere Erstreckung aus dem Bahnbereich und anderseits eine stabilere Verformung quer zum Bahnbereich ergibt.The invention has for its object a film of the type mentioned To improve so that the disadvantages mentioned are avoided. this will achieved according to the invention in that the film strip by means of waves extending across the entire width of the film transverse to the longitudinal direction of the strip and is profiled to the film surface. This cross-profiling is retained during stretching, so that deformation occurring out of the band level during the stretching itself in addition to the profiling, which on the one hand results in a higher extension from the Web area and on the other hand results in a more stable deformation transverse to the web area.

Die Profilierung des Folienbandes ist durch sich über die gesamte Folienbreite erstreckende Wellen gebildet, was eine einfache kontinuierlich herstellbare Profilierung ergibt. Für eine noch größere Festigkeit der Folie quer zur Bandebene kann die wellenförmige Profilierung kantige Übergänge aufweisen.The profiling of the foil tape is inherent Waves extending over the entire width of the film formed what simple, continuously producible profiling results. For an even bigger one Firmness of Foil transversely to the plane of the tape, the wavy profile can have angular transitions exhibit.

Bei einem vorteilhaften Verfahren zur Herstellung eines Füllmaterials der eingangs genannten Art, bei welchem Verfahren ein Folienband aus Metall, insbesondere, oder aus formbeständigem, flexiblem Material, insbesondere Kunststoff, mit gleichmäßig verteilten, parallel zueinander und zur Bandlängsrichtung verlaufenden Schlitzen versehen und danach quer zur Längsrichtung gestreckt wird, wird zwischen dem Einbringen der Schlitze und dem Strecken des Bandes letzteres durch Einbringen von sich über die gesamte Bahnbreite erstreckenden Wellen profiliert, wodurch ein besonders gut profiliertes Füllmaterial erreicht wird.In an advantageous method for the production of a filler material mentioned type, in which method a foil strip made of metal, in particular, or from dimensionally stable, flexible material, especially plastic, with even distributed, parallel to each other and to the tape longitudinal direction slots is provided and then stretched transversely to the longitudinal direction, between the introduction of the slits and stretching the tape the latter by introducing itself over the entire web width extending waves profiled, whereby a particularly well profiled filling material is achieved.

Eine Vorrichtung zur Durchführung des vorstehend angeführten Verfahrens mit einem Förderer für die Folie, einem Schneidwerkzeug zur Bildung von intermittierenden Schlitzen in der Folie und einer Einrichtung zur Streckung der mit den Schlitzen versehenen Folie, und welche Einrichtung eine Klemmeinrichtung fiir die Folienlängskanten und einen ansteigenden Auflaufkörper aufweist, ist erfindungsgemäß dadurch gekennzeichnet, daß der Einrichtung zur Streckung der Folie eine Profiliereinrichtung zur wellenförmigen Profilierung des mit den Schlitzen versehenen Folienbandes vorgeschaltet ist. Eine derartige Einrichtung ermöglicht auf besonders einfache Weise die kontinuierliche Herstellung eines solchen Füllmaterials.A device for carrying out the above-mentioned method with a conveyor for the film, a cutting tool to form intermittent Slits in the film and a device for stretching the with the slits provided film, and which device a clamping device for the film longitudinal edges and has a rising casserole, according to the invention characterized in that the device for stretching the film has a profiling device upstream for the wavy profiling of the film strip provided with the slots is. Such a device enables the in a particularly simple manner continuous production of such a filler.

Da erfindungsgemäß die Profiliereinrichtung durch ein ineinandergreifendes Profilwalzenpaar gebildet ist, wird eine Profilierung durch rollende Werkzeuge erreicht, die eine hohe Verarbeitungsgeschwindigkeit zulassen. Für eine zuverlässige Förderung und auch Klemmung des Randes der Folienbahn in der Klemmeinrichtung kann das durch die Profilwalzen in die Folien eingebrachte Profil jenem der Klemmeinrichtung für die Folienlängskanten entsprechen. Dabei kann das Profil der Klemmeinrichtung an den Rändern zweier Klemmräder vorgesehen sein, die an ihren profilierten Umfangsflächen über einen Teil des Umfangs von einem Klemmriemen umschlossen ist. Auch diese Einrichtung bildet somit eine einen kontinuierlichen gleichförmigen Vorschub erzielende Einrichtung. Für den gleichen Zweck und für eine hohe Vorschubgeschwindigkeit kann der beiden Klemmrädern zukommende Mittelpunkt exzentrisch zum Mittelpunkt eines rotierenden Streckkörpers angeordnet sein, wobei die maximale Exzentrizität im Bereich des vom Klemmriemen umschlossenen Teils der Klemmräder liegt. Auf diese Weise ist es möglich, ohne Schmierung des Materials bei seinem Durchgang durch die Einrichtung auszukommen, was insbesondere dann wesentlich ist, wenn das Füllmaterial, z.B. durch Lacke oder sonstige Beschichtungen, weiterbehandelt wird.Since according to the invention the profiling device by an interlocking Profile roller pair is formed, profiling by rolling tools achieved that allow a high processing speed. For a reliable Promotion and also clamping of the edge of the film web in the clamping device can the profile introduced into the foils by the profile rollers that of Corresponding clamping device for the film longitudinal edges. The profile of the Clamping device can be provided on the edges of two clamping wheels, which on their profiled peripheral surfaces over part of the circumference of a clamping belt is enclosed. This device also forms a continuous one Uniform feed device. For the same purpose and for one high feed rate can be the center of the two clamping wheels be arranged eccentrically to the center of a rotating stretch body, where the maximum eccentricity in the area of the enclosed by the clamping belt Part of the pinch wheels. In this way it is possible without lubricating the Materials get along as he passes through the facility, which in particular is essential if the filling material, e.g. through paints or other coatings, is treated further.

In einer Ausführungsvariante kann der Klemmriemen als Flachriemen ausgebildet sein, der an den äußeren Umfangsflächen der radial nach außen gerichteten Vorsprünge der an ihrer Umfangsfläche profilierten Klemmränder anliegt. Dies hat den Vorteil, daß die Bahnränder nicht über die gesamte Länge, sondern nur streckenweise geklemmt werden, sodaß während des Streckens im Bereich der Klemmungen eine Streckung bis ganz an den Rand erfolgen kann, wogegen jene Bereiche, die zwischen den Klemmungen liegen, nicht so stark gestreckt werden, sodaß sich der Folienrand wellenförmig nach innen bewegt. Dies ist dann vorteilhaft, wenn in den Behälter Wikkel von dem gestrecken Folienmaterial eingebracht werden, die über ihre flachen Seitenbereiche aufeinanderliegen. Damit kommt es zu einem gegenseitigen Verhaken der Wickel, die durch die unebene Oberfläche gegen ein gegenseitiges Verschieben gehindert sind.In one embodiment variant, the clamping belt can be designed as a flat belt be on the outer peripheral surfaces of the radially outward projections the clamping edges profiled on its peripheral surface. This has the Advantage that the web edges are not over the entire length, but only in sections be clamped so that a while stretching in the area of the clamps Stretching can be made to the very edge, whereas those areas between the clamps are not stretched so much that the film edge waved inwards. This is advantageous when winding into the container of the stretched film material are introduced over their flat side areas lie on one another. This leads to mutual interlocking of the Wraps that are prevented from moving by the uneven surface are.

Bei einer anderen Ausführungsform kann der Klemmriemen als Profilriemen ausgebildet sein, dessen Profilierung nach außen gerichtet ist und ein zu den Klemmriemen gegengleiches Querprofil aufweist, wodurch die Folienränder über ihre ganze Länge gehalten sind, u.zw. derart, daß aufgrund der Vorprofilierung der Folienbahn das Profil nach Art eines Zahnrades in das Außenprofil der Klemmräder eingreift und durch den Zahnriemen in dieser Stellung gehalten wird. Dabei kann im Bereich der maximalen Exzentrizität der Abstand zwischen dem Umfang des Streckkörpers und der Klemmeinrichtung größer sein als die halbe Breite des gestreckten Materialbandes, was dazu führt, daß noch im Klemmungsbereich die Materialränder zwischen den Klemmteilen herausgezogen werden, wodurch sichergestellt ist, daß die Streckung des Bandes bis in den Randbereich erfolgt und nicht, wie bei früheren Ausbildungen, die Randbereiche ungestreckt bleiben.In another embodiment, the clamping belt can be used as a profile belt be formed, the profile of which is directed outwards and to the clamping belt has opposite cross profile, whereby the film edges over their whole Length, etc. such that due to the pre-profiling of the film web Profile engages like a gear in the outer profile of the clamping wheels and is held in this position by the toothed belt. It can in the area of maximum eccentricity the distance between the circumference of the stretch body and the Clamping device be larger than half the width of the stretched material band, what leads to the fact that the material edges between the clamping parts still in the clamping area can be pulled out, ensuring that the stretching of the tape to the edge area and not, as in previous training, the edge areas stay undrawn.

Der rotierende Streckkörper kann frei drehbar gelagert sein, was den Vorteil hat, daß er einzig und allein durch das darübergezogene Band bewegt wird, sodaß Relativ-geschwindigkeiten zwischen dem Band und dem Streckkörper vermieden sind und das Band in der gewünschten Streckung über dem rotierenden Streckkörper abrollt. Zusätzlich kann schließlich der rotierende Streckkörper selbst exzentrisch gelagert sein, wodurch eine noch größere Unregelmäßigkeit erzielt ist.The rotating stretch body can be freely rotatably supported, which has the advantage that it is moved solely by the band pulled over it, so that relative speeds between the belt and the stretch body are avoided and that Roll the tape in the desired stretch over the rotating stretch body. In addition, the rotating stretch body itself can finally be mounted eccentrically be, whereby an even greater irregularity is achieved.

Die eingangs genannten Füllkörper können dabei nicht nur zum Befüllen von Behältern für explosionsgefährdete Fluids angewendet werden, sondern es hat sich herausgestellt, daß derartige Füllkörper auch in Sonnenkollektoren sehr wirkungsvoll sind, da bei geschwärzten Füllfolien ein Reflektieren der eingestrahlten Lichtmenge nicht erfolgen kann, sondern vielmehr die eingestrahlte Sonnenenergie aufgrund der inneren Reflexionen in dem Material gehalten wird, was zu einer besonders guten Erwärmung des den Sonnenkollektor durchströmenden Wassers oder Luft führt.The fillers mentioned at the beginning can not only be used to fill Containers for explosive fluids are applied, but it has been found that such fillers are also very effective in solar collectors, since the blackened filler foils do not reflect the amount of light irradiated can, but rather the incident solar energy due to the inner Reflections are kept in the material, which leads to particularly good heating of water or air flowing through the solar collector.

    Wie aus Fig. 4 erkennbar, besteht die Profiliereinrichtung aus zwei Profilierwalzen 12, 13, die an ihrem Außenmantel mit regelmäßigen Längsrippen versehen sind, wobei die Längsrippen der einen Rollen in die Zwischenräume zwischen den Längsrippen der anderen Rollen eingreifen, also ineinander verzahnt sind. Durch den Spalt zwischen den beiden Profilierrollen 12, 13 wird das Folienband 1, das bereits mit den in Längsrichtung des Bandes verlaufenden Einschnitten versehen ist, hindurchgeführt und an die Streckstation 8 übergeben. Diese Streckstation weist zwei Klemmräder auf, die voneinander distanziert sind, wobei die mittlere Entfernung dieser beiden Klemmräder etwa der Breite des aus der Profiliereinrichtung kommenden Folienbandes entspricht. Die Klemmräder weisen an ihrer Außenseite eine Profilierung auf, u.zw. eine Verzahnung, die der Verzahnung der Profilierrollen entspricht, sodaß das von der Profiliereinrichtung 7 kommende, mit Wellen versehene Folienband 1 direkt in die Verzahnung der Klemmräder 14, 15 eingreift. Über einen Teil des Umfanges der Klemmräder 14, 15 ist ein Riemen 16, 17 herumgeführt, u.zw. gemäß dem dargestellten Ausführungsbeispiel ein Zahnriemen, dessen Verzahnung nach außen gerichtet ist und in die Verzahnung der Klemmräder 14, 15 eingreift, u.zw. derart, daß die Riemen die Folienbahn 1 an den Klemmrädern 14, 15 festhält. Die Klemmriemen 16, 17 sind dabei über Umlenkrollen 18, 19, 20, 21 und 22, 23 geführt, wobei der Berührungsbereich etwa 1/4 des Umfanges der Klemmräder 14, 15 betrifft. Wie aus den Fig. 4 und 5 ersichtlich ist, sind die Rollen 18, 20 bzw. 19, 21 direkt übereinander angeordnet, was in Fig. 5 dadurch angedeutet ist, daß die Bezugszeichen 18 und 19 mit strichlierten Bezugszeichen auf die Rollen 20 und 21 gerichtet sind, was - wie aus Fig. 4 erkennbar ist - andeutet, daß die Rollen 18, 19 direkt unterhalb der Rollen 20, 21 angeordnet sind. Zwischen den beiden Klemmrädern 14, 15 ist ein Streckkörper 24 angeordnet, welcher durch ein frei drehbar gelagertes Streckrad gebildet ist, wobei der Außenmantel des Streckrades durch die Mantelflächen von zwei mit ihrer Basis aneinander angrenzenden Kegelstümpfen gebildet ist. Diese Formgebung ermöglicht ein besonders gutes Strecken nach beiden Richtungen, u.zw. auch im Mittelbereich, ohne eine zu starke Knickung herbeizuführen. As can be seen from Fig. 4, the profiling device consists of two profiling rollers 12, 13, which are provided with regular longitudinal ribs on their outer jacket, wherein the longitudinal ribs of the one roller into the spaces between the longitudinal ribs the other roles intervene, that is, they are interlocked. Through the gap between the two profiling rollers 12, 13 is the film strip 1, which is already with the in Is provided in the longitudinal direction of the tape extending cuts, passed and handed over to the stretching station 8. This stretching station has two clamping wheels that are spaced from each other, the average distance of these two pinch wheels corresponds approximately to the width of the film strip coming from the profiling device. The clamping wheels have a profile on their outside, etc. a gear, which corresponds to the toothing of the profiling rollers, so that the profiling device 7 coming, corrugated foil tape 1 directly into the toothing the pinch wheels 14, 15 engages. Over part of the circumference of the pinch wheels 14, 15, a belt 16, 17 is guided around, etc. according to the illustrated embodiment a toothed belt, the toothing of which is directed outwards and into the toothing the pinch wheels 14, 15 engages, etc. such that the belts the film web 1 holds on the pinch wheels 14, 15. The clamping belts 16, 17 are over pulleys 18, 19, 20, 21 and 22, 23 guided, the contact area about 1/4 of The scope of the pinch wheels 14, 15 relates. As can be seen from FIGS. 4 and 5, are the rollers 18, 20 and 19, 21 arranged directly one above the other, which in Fig. 5 thereby is indicated that the reference numerals 18 and 19 with dashed reference numerals the rollers 20 and 21 are directed, which - as can be seen from Fig. 4 - indicates that the rollers 18, 19 are arranged directly below the rollers 20, 21. Between two clamping wheels 14, 15, a stretching body 24 is arranged, which by a free rotatably mounted stretching wheel is formed, the outer casing of the stretching wheel through the lateral surfaces of two truncated cones with their bases adjoining one another is formed. This shape enables particularly good stretching in both directions, etc. also in the middle area without too much kinking bring about.

    Wie aus Fig. 4 erkennbar ist, ist das Streckrad 24 exzentrisch zu den Klemmrädem 14, 15 gelagert, wobei die größte Exzentrizität nach dem Lösebereich der Folienbahn 1 aus der Klemmung zwischen den Klemmriemen 16, 17 und den Klemmrädern 14, 15 angeordnet ist. Die größte Entfernung zwischen dem Außenumfang des Klemm-rades 24 und dem Umfang der Klemmräder 14, 15 ist dabei größer als die Breite des gestreckten Materials, wodurch - wie schon eingehend dargelegt - erreicht wird, daß das Folienband quer aus der Klemmung zwischen den Klemmrädern und den Klemmriemen herausgezogen wird, sodaß die Streckung bis in den äußersten Randbereich der Folienbahn erfolgt.As can be seen from Fig. 4, the stretching wheel 24 is eccentric to the clamping wheels 14, 15 mounted, the greatest eccentricity after the release area of the film web 1 from the clamping between the clamping belts 16, 17 and the clamping wheels 14, 15 is arranged. The greatest distance between the outer circumference of the pinch wheel 24 and the circumference of the clamping wheels 14, 15 is larger than the width of the stretched material, which - as already explained in detail - achieves that the foil tape transversely from the clamping between the clamping wheels and the clamping belt is pulled out, so that the extension to the extreme edge of the Foil web is done.

    In Fig. 6 ist ersichtlich, wie die Folienbahn durch die Streckung verändert wird. Das vor der Profiliereinrichtung zwischen die Walzen 12, 13 eingeführt Folienband 1 mit seinen Schlitzen 1' wird bereits beim Aufwärtsführen über das Streckrad 24 vorgestreckt, wobei die Streckung und das Lösen durch die immer breiter werdenden Öffnungen 2 deutlich erkennbar ist.6 shows how the film web is changed by the stretching. The foil strip 1 inserted between the rollers 12, 13 in front of the profiling device with its slits 1 'is already stretched over the stretching wheel 24 when it is guided upwards, the stretching and loosening through the increasingly wider openings 2 is clearly recognizable.

    5 In nicht dargestellter Weise können die Klemmriemen 16, 17 auch als Flachriemen ausgebildet sein, sodaß sie nur an den äußeren Oberflächen der nach außen vorspringenden Profile der Klemmräder anliegen, sodaß die Klemmung nur dort lokal erfolgt und die Folienbahn 1 im Bereich der Vertiefungen zwischen den Vorsprüngen der Klemmräder nicht gehalten ist. Dies führt dazu, daß die Streckung im Bereich der Anlage an den Außenflächen der Vorsprünge stärker erfolgt als zwischen den Vorsprüngen, sodaß eine leicht wellige Außenberandung der Folienbahn erzielt wird.5 In a manner not shown, the clamping belts 16, 17 can also be used as flat belts be formed so that they protrude only on the outer surfaces of the outward Profiles of the clamping wheels are in contact, so that the clamping only takes place locally there and the film web 1 in the region of the depressions between the projections of the Clamping wheels are not held. This leads to the stretch in the area of the system occurs more on the outer surfaces of the projections than between the projections, so that a slightly wavy outer edge of the film web is achieved.

    In ebenfalls nicht dargestellter Weise kann auch der rotierende Streckkörper selbst exzentrisch gelagert sein, was noch zusätzlich die Unregelmäßigkeiten der Strekkung erhöht und einen wellenförmigen Rand ergibt, der eine größere Wellenlänge als die Wellung auf Grund der Verwendung der Flachriemen aufweist.In a manner not shown, the rotating stretching body can also itself be eccentrically mounted, which also adds to the irregularities of the stretch increases and gives a wavy edge that is longer than the corrugation is due to the use of the flat belt.
