Abstract

The material has in known manner two spaced superimposed plate or sheet type elements supported in the spaced state at a large number of positions, but modified so that the elements each consist of a sealed fibre fleece, and at least one is provided with a series of projections or raised parts, at which the two elements are welded together. The elements pref. consist of a heat-sealed continuous filament fleece from highly stretched thermoplastic yarns.

Description

Verpackungs-, Leichtbau- oder Isolierstoff Die Erfindung betrifft einen voluminösen Verpackungs-, Leichtbau- oder Isolierstoff aus Kunststoff, der aus mindestens zwei Abstand voneinander besitzenden und untereinander an einer Vielzahl von Stellen abgestUtæten platten- oder folienartigen Elementen besteht, und ein Verfahren zu seiner Herstellung. Packaging, lightweight or insulating material The invention relates to a voluminous packaging, lightweight construction or insulating material made of plastic that from at least two distance from each other and from one another to a large number consists of plate-like or foil-like elements staggered by places, and a Process for its manufacture.

Es ist in diesem Zusammenhang bereits bekannt, herkömmliche Wellpappe zu verwenden. Solche Wellpappe ist zwar relativ stabil, jedoch nicht wasserfest, nicht chemikalienbestäpdig, nicht reißfest, nicht verschleißfest und es sind keine dauerhaften Gegenstände daraus herstellbar.It is already known in this context, conventional corrugated cardboard to use. Such corrugated cardboard is relatively stable, but not waterproof, not resistant to chemicals, not tear-resistant, not wear-resistant and there are none durable objects can be produced from it.

Eine Verbesserung bringt die Verwendung von kunstharzgetränkter Wellpappe. Diese ist zwar wasserfest und bedingt chemikalienbeständig, nachteilig weist sie jedoch höheres Gewicht, ungenügende Reißfestigkeit, geringe Atmungsaktivität sowie eine niedrige Stoßfestigkeit und ElastizitS; insbesondere bei Kälte auf.The use of synthetic resin-soaked corrugated cardboard brings an improvement. Although this is waterproof and partially resistant to chemicals, it has a disadvantage however, higher weight, insufficient tear resistance, low breathability as well low impact resistance and elasticity; especially when it's cold.

Wellpappe aus thermoplastischem Kunststoff weiterhin, die einen Aufbau wie Wellpappe, jedoch bestehend aus drei aufgeschäumten bzw. gemeinsam extrudierten thermoplastischen Kunststoffschichten aufweist, hat die Nachteile, daß ihr Gewicht und Materialaufwand relativ hoch ist. Die Atmungsaktivität ist nicht auf den fUr den Jeweiligen Verwendungszweck optimalen Wert einstellbar. Ebenso ist die Weiterreißfestigkeit sehr gering, was sich bei beschädigten Teilen sehr nachteilig auswirkt.Thermoplastic corrugated cardboard continues to have a structure like corrugated cardboard, but consisting of three foamed or jointly extruded Has thermoplastic plastic layers, has the disadvantages that their weight and the cost of materials is relatively high. The breathability is not on the for The optimal value can be set for the respective purpose. The same is the tear strength very low, which has a very negative effect on damaged parts.

Aufgabe der Erfindung ist es daher, einen Verpackungsstoff zu schaffen, der auch als Leichtbau- oder Isolierstoff ein setzbar die Nachteile der Stoffe nach dem Stand der Technik nicht mehr aufweist und sich insbesondere durch hohe Steifigkeit, erhöhte Reiß- und Verschleißfestigkeit gegenüber herkömmlichen Elementen, wesentlich geringeres Gewicht, einstellbare Atmungsaktivität bei gleichzeitiger FlUssigkeitsdichtheit, Verformbarkeit in praktisch allen Richtungen (Biegen, Abkanten etc.), Wärme- und Kältebeständigkeit, gute Reinigungsmöglichkeit, Seewasserfestigkeit, erhöhte Stoßfestigkeit, Chemikalienbeständigkeit, physiologische Unbedenklichkeit, Geschmacks- und Geruchsneutralität u. dergl. auszeichnet.The object of the invention is therefore to create a packaging material which can also be used as a lightweight construction or insulating material, following the disadvantages of the materials no longer corresponds to the state of the art and is characterized in particular by high rigidity, increased tear and wear resistance compared to conventional elements, significantly lower weight, adjustable breathability with simultaneous liquid-tightness, Deformability in practically all directions (bending, folding, etc.), heat and Cold resistance, easy to clean, seawater resistance, increased shock resistance, Chemical resistance, physiological harmlessness, taste and odor neutrality and the like.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei dem eingangs erwähnten Verpackungs Leichtbau- oder Isolierstoff die platten- oder folienartigen Elemente aus versiegelten Faservliesen bestehen, mindestens eine der platten- oder folienartigen Elemente eine Vielzahl von Vorsprüngen oder Erhöhungen aufweist und die platten- oder folienartigen Elemente an diesen Vorsprüngen oder Erhöhungen miteinander verschweißt sind.According to the invention, this object is achieved in that in the case of the initially mentioned packaging lightweight or insulating material the plate or film-like Elements consist of sealed nonwovens, at least one of the plate or film-like elements has a plurality of projections or elevations and the plate-like or film-like elements on these projections or elevations with one another are welded.

Uberraschenderweise weist das neuartige Element weiterhin eine höhere Festigkeit auf, als von einem Fachmann erwartet werden kann.Surprisingly, the novel element continues to have a higher level Strength than can be expected by a person skilled in the art.

Vorteilhaft bestehen die Elemente aus einem heißversiegelten Endlosfadenvlies aus hochverstreckten Fäden eines thermoplastischen Kunststoffes und werden durch das Heißversiegln von Vliesbahnen, Prägen der heißversiegelten Vliesbahnen, Zusammenführen der geprägten Vliesbahnen und Verschweißen der Vliesbahnen hergestellt, wobei vorteilhaft das Verfahren kontinuierlich unter Verwendung von Prägewalzen bzw. Prägebändern und Schweißvorrichtungen erfolgt.The elements advantageously consist of a heat-sealed continuous thread fleece made of highly drawn threads of a thermoplastic material and are made by the heat sealing of nonwoven webs, embossing of the heat sealed nonwoven webs, merging of the embossed nonwoven webs and welding the nonwoven webs produced, being advantageous the process continuously using embossing rollers or embossing belts and welding devices.

Ijindestens zwei je Anwendungsfall mehr oder weniger stark heiI3versiegelte Faservliese, insbesondere Endlosfaservliese aus thermoplastischem Kunststoff, deren Oberflächen mit durch Prägung hergestellten kleinen Vertiefungen bzw. Erhöhungen versehen sind, werden derart aufeinander gefXlrt, daß jeweils die Erhöhungen des einen Flächenelementes auf den Erhöhungen des anderen Flächenelementes aufliegen, so daß die Summe der Erhöhungen die Distanz zwischen beiden Flächenelementen bestitu-nen. Durch Verschweißen der Vliesbahnen an ihren Auflagestellen werden diese zu einem Sandwichelement von vorzugsweise 1 bis ca. 20 mm Dicke verbunden. Bei mehr als zweilagigen Elementen werddn die innen befindlichen Elemente .versetst sowohl mit Erhöhungen als auch Vertiefungen durch Prägung versehen, um den erreichbaren Abstand zur davorliegenden bzw. nächsten Lage zu erhöhen, wodurch die Anzahl der erforderlichen Lagen zur erlangung der geforderten Gesamtdicke auf ein Minimum reduziert wird. Die Verschweißung geschieht wiederum an den jeweiligen BerUhrungspunkten der einzelnen Lagen.At least two more or less heat-sealed for each application Fiber fleeces, in particular continuous fiber fleeces made of thermoplastic material, their Surfaces with small depressions or elevations produced by embossing are provided, are flown on each other in such a way that the increases in the one surface element rest on the elevations of the other surface element, so that the sum of the elevations determines the distance between the two surface elements. By welding the fleece webs at their support points, they become one Sandwich element of preferably 1 to about 20 mm thick connected. With more than two layers Elements are the elements located inside. Versetst both with elevations as well as indentations provided by embossing to the achievable distance to the one in front or to increase the next layer, thereby increasing the number of layers required the required total thickness is reduced to a minimum. The welding takes place again at the respective contact points of the individual layers.

Es kann auch bei zweilagigen Flächenelementen wahlweise nur eines der beiden Elemente mit Erhöhungen versehen und die Gegenseite glatt ausgebildet sein. Bei mehrlagigen Elementen kann eine oder beide Außenlagen glatt ausgebildet sein. Die Verbindung der Einzelteile erfolgt in allen Fällen durch Schweißen. Die Erhöhungen bzw. Vertiefungen werden markant geprägt, damit eine stützende Wirlnung erreicht wird. Sie können praktisch Jede beliebige Form, z. B. rund, rechteckig, ovSl odereine ähnliche aufweisen. Gemischte Formen sind zur Erzielung bestimmter Eigenschaften und Oberflächeneffekte ebenfalls möglich.In the case of two-layer surface elements, only one can be selected of the two elements provided with elevations and the opposite side smooth be. In the case of multi-layer elements, one or both outer layers can be smooth be. In all cases, the individual parts are connected by welding. the Elevations or depressions are markedly embossed, so that a supportive effect is achieved. They can be practically any shape, e.g. B. round, rectangular, ovSl or a similar one. Mixed forms are used to achieve certain Properties and surface effects are also possible.

Im folgenden werden AusfUhrungsbeispiele der Erfindung anhand der Zeichnungen beschrieben.In the following exemplary embodiments of the invention are based on the Drawings described.

Es zeigen: Fig. 1 einen Querschnitt durch eine AusfUhrungsform des neuartigen Elementes; Fig. 2 einen Ausschnitt von Fig0 1; Fig. 3 eine Aufsicht auf ein Element gemäß Fig0 1; Fig. 4 einen Karton aus Elementen gemäß Fig0 1; Fig. 5 einen Querschnitt durch eine weitere Ausführungsform des neuartigen Elementes; Fig. 6 eine Vergrößerung von Fig0 5; Figo 7 eine Aufsicht auf ein Element gemäß Fig 5; Fig. 8, 9 und 10 Aufsichten auf Elemente gemäß der Erfindung mit erhöhter und gleichmäßiger Biegesteifigkeit; Fig. 11 den kontinuierlichen Verfahrensablauf gemäß der Erfindung; Fig. 12 den kontinuierlichen Verfahrensablauf gemäß der Erfindung zur Herstellung einer sechslagigen Platte; Fig. 13 einen Schnitt durch eine Platte mit drei Lagen, Fig. 14 eine sechslagige Platte im Teilschnitt und Querschnitt; Fig. 15 einen Behälter aus den Elementen gemäß der Erfindung und Fig, 16 ein Element mit eingeprägten Knickkanten zur Herstellung eines Behälters gemäß Fig. 150 Das erfindungsgemäße Verfahren arbeitet wie folgt: Die heißversiegelten, in der Regel aufgespulten Vliesbahnen werden zwischen jeweils nachgeschalteten, über ein Getriebe miteinander verbundene g d synchron laufenden Prägewalzenpaaren bzw. Prägebänderpaaren (jeweils Patrize und Matrize) bei Temperaturen unterhalb des Schmelzpunlftes des betreffenden Materials in bekannter Weise geprägt, und zwar so, daß die zu verschweißenden Erhöhungen der entsprechenden Lagen gegeneinander geführt werden. Die Ausprägung muß sehr markant erfolgen, um entsprechende Steifigkeit zu erhalten.They show: FIG. 1 a cross section through an embodiment of the novel element; FIG. 2 shows a detail from FIG. 1; FIG. Fig. 3 a plan view of an element according to Fig0 1; Fig. 4 shows a carton made of elements according to Fig0 1; Fig. 5 is a cross section through a further embodiment of the novel Element; FIG. 6 shows an enlargement of FIG. 5; 7 shows a plan view of an element according to FIG. 5; 8, 9 and 10 are plan views of elements according to the invention with an increased and uniform flexural rigidity; 11 shows the continuous process sequence according to the invention; 12 shows the continuous process sequence according to the invention for the production of a six-layer board; 13 shows a section through a plate with three layers, FIG. 14 a six-layer plate in partial section and cross-section; 15 shows a container made from the elements according to the invention; and FIG. 16 shows an element with embossed kinked edges for the production of a container according to FIG. 150 The The inventive method works as follows: The heat-sealed, usually spooled nonwoven webs are between each downstream, via a gear interconnected g d synchronously running embossing roller pairs or embossing belt pairs (both male and female) at temperatures below the melting point of the relevant material shaped in a known manner, in such a way that the to be welded Elevations of the corresponding layers are led against each other. The expression must be made very prominent in order to obtain adequate rigidity.

Die nun geprägten und zu verschweißenden Bahnen laufen mit gleicher Geschwindigkeit über ein Heizelement zur Aufheizung zu gegeneinander angeordneten Führungsblechen, die einmal den erforderlichen Schweißdruck und zum anderen die Kalibrierung und Geradeführung bei gleichzeitiger lUhlung übernehmen. Das Heizelement wird vorzugsweise als Heizkeil ausgebildet, der einen Winkel hat, der etwa dem Winkel der in die Kalibrierzone einlaufenden Bahnen entspricht, oder eine Krümmung aufweist, die der Einlaufform der Kalibrierzone entspricht.The strips that are now embossed and to be welded run with the same Speed via a heating element to heat up against each other Guide plates that provide the required welding pressure on the one hand and the Take over calibration and straight line guidance with simultaneous cooling. The heating element is preferably designed as a hot wedge which has an angle that is approximately the same as the angle corresponds to the paths entering the calibration zone or has a curvature, which corresponds to the inlet shape of the calibration zone.

Der inlaufde's Kalibrierkanals ist entweder mit einer speziellen Einlaufkurve oder einem Einlaufkonus versehen' mindestens aber an der Einlaufkante abgerundet. Die speziell abgestimmte Form von Heizkeil und Einlauf erlaubt eine Steuerung der Aufheizung der Bahnen zur Verschweißung der Grenzschichten, d. h. der Erhöhungen, durch Veränderung des Kontaktdruckes bzw. der Kontaktfläche. Dadurch wird neben der Steuerung mittels Variation der Geschwindigkeit der ablaufenden Bahnen und der Temperatur des Heizkeils eine individuelle Regelung ermöglicht. Der Heizkeil kann elektrisch beheizt werden, wie dies z. B. beim Abkantschweißen oder bei Heizkeilen zur Herstellung von Folienüberlappungsnähten geschieht. Andere Energiearten sind ebenso möglich.The inlaufde's calibration channel is either with a special inlet curve or provided with an inlet cone, but at least rounded at the inlet edge. The specially coordinated shape of the hot wedge and inlet allows the Heating of the webs for welding the boundary layers, d. H. of the increases, by changing the contact pressure or the contact area. This will next the control by varying the speed of the running paths and the Temperature of the hot wedge allows individual control. The hot wedge can be electrically heated, as z. B. when bending or heating wedges for the production of foil overlap seams. Other types of energy are also possible.

Der erfindungsgemäße Heizkeil arbeitet im Gegensatz zu den bekannten Heizelementen gleichzeitig über die gesamte Breite der Bahn verlaufend und bewirkt durch gleitende Wärmeübertragung, z. B. durch Kontakt, eine kontinuierliche Aufschmelzung der zu verschweißenden Grenzschichten über die gesamte Bahnbreite. Hierdurch wird erfindungsgemäß auf einfache Art die ganzflächige Verschweißung zweier oder mehrerer erfindungsgemäßer Vliese ermöglicht. Zur Erreichung mehrerer Lagen wird den so verschweißten Elementbahnen ein- oder beidseitig wiederwn über entsprechende HeiSiemente eine oder zwei neue magen mit gleicher Geschwindigkeit zugeführt, welche zwischen zwei weiteren Kalibrierflächen verschweißt und abgelcühlt werden. Die Anzahl der übereinander zu verschweißenden Lagen wird somit durch fIintereinanderschaltung einer entsprechenden Anzahl von Präge- und Schweißeinheiten erreicht. Im Falle glatter Decklagen werden ungeprägte, jedoch synchron laufende Vliesbahnen in die letzte Schweißeinheit eingeführt.The hot wedge according to the invention works in contrast to the known ones Heating elements running simultaneously over the entire width of the web and causes by sliding heat transfer, e.g. B. by contact, continuous melting of the boundary layers to be welded across the entire width of the web. This will according to the invention, the whole-area welding of two or more in a simple manner according to the invention allows nonwovens. In order to reach several layers, it is welded in this way Repeat element tracks on one or both sides using appropriate heating elements or two new stomachs fed at the same rate, which between two further calibration surfaces are welded and cooled. The number of one on top of the other The layers to be welded are thus created by interconnecting a corresponding Number of stamping and welding units reached. In the case of smooth top layers Unembossed, but synchronously running fleece webs are introduced into the last welding unit.

Do Endlosfaservliese vorzugsweise aus hochverstrecktens thermoplastischen Fasern bestehen, dürfen bei der Verschweißung nur die zu verschweißenden Granzflächen auf die Schweißtemperatur erwärmt werden, um Schädigungen zu vermeiden. Hierzu kann es gegebenenfalls erforderlich seinp zwischen Prägeeinrichtung und Schweißeinrichtung eine Kühletrecke vorzusehen, um zu erreichen, daß nur die su verschweißenden Grenzschichten, jedoch nicht die gesamte Vliesdicke auf die Schmelztemperatur erwärmt wird, Die Zwischenkühlung erfolgt in der Regel durch bekannte Methoden, wie Gebläse oder Kühlkanäle bzwO Kühlwalzen.Do continuous fiber fleeces preferably made of highly stretched thermoplastic If there are fibers, only the border areas to be welded are allowed to be welded heated to the welding temperature in order to avoid damage. Can do this it may be necessary between the embossing device and the welding device to provide a cooling section in order to ensure that only the boundary layers to be welded however, not the entire thickness of the fleece is heated to the melting temperature Intermediate cooling is usually carried out using known methods, such as fans or cooling channels or chill rolls.

Bei extrem dünnwandigen und leichten Flächenelementen ist es vorteilhaft, zur Erreichung der erforderlichen Schweißdrücke anstelle des Kalibrierkanals entsprechend der Prägung der Bahnen ausgebildete Kalibrierwalzen zu verwenden. Ebenso ist es möglich, bei festeren Elementen anstatt der Kalibrierkanäle mit rotierenden Kalibrierwalzen zu arbeiten.In the case of extremely thin-walled and light surface elements, it is advantageous to to achieve the required welding pressures instead of the calibration channel to use the embossing of the webs trained calibrating rollers. It is the same possible, with more rigid elements instead of the calibration channels with rotating calibration rollers to work.

Nachgeschaltete Transport- bzw. Abzugswalzen sorgen für einen gleichmäßigen Weitertransport des verschweißten Elementes.Downstream transport or take-off rollers ensure a uniform Further transport of the welded element.

Die Elemente werden je nach Steifigkeit einer Wickelvorrichtung oder einer Schneidvorrichtung, die wahlweise mit Schwermessern oder einem Glühdraht arbeiten kann, zugeführt Zum Zwecke einer guten Führung des Materials und um ein Kleben an dem Maschinenteil zu verhindern, sind die gefährdeten Stellen vorteilhaft entweder galvanisiert, PTFE-beschichtet oder anderweitig oberflächenbehandelt.The elements are depending on the stiffness of a winding device or a cutting device that works either with heavy knives or a glow wire can, fed for the purpose of a good guidance of the material and to stick to it To prevent the machine part, the endangered areas are beneficial either galvanized, PTFE-coated or otherwise surface-treated.

Die gesamte Anlage kann entweder direkt hinter die Produktionsanlage von Vlies angeschlossen werden oder separat arbeiten, indem bereits versiegelt angeliefertes Vlies aufgetrommelt vom Weiterverarbeiter eingesetzt wird. Im ersten Fall kann das Prägen und das Heißversiegeln in einem Arbeitsvorgang vorgenommen werden. In der Regel ist es jedoch vorteilhaft, die Prägung und Verschweißung der Bahnen in einer Anlage direkt hintereinander durchzuführen, da hierbei die Schwierigkeiten der Synchronisation geringer sind, als bei fertiggeprägt angelieferten und ausgelagerten Vliesen. Bei der direkten Hintereinanderschaltung von Vliesherstellung und erfindungsgemäßer Weiterverarbeitung ist darauf zu achten, daß sich die Produktionsgeschwindigkeiten der Herstellung des Vlieses und der Weiterverarbeitung aufeinander abstimmen lassen. Weiterhin sind für die Herstellung des Vlieses je nach der Lagenanzahl die entsprechenden Einrichtungen zur Erreichung der notwendigen Lagen erforderlich.The entire plant can either be placed directly behind the production plant can be connected by fleece or work separately by using what is already sealed Fleece is rolled up and used by the processor. In the first case it can Embossing and heat sealing can be done in one operation. In the As a rule, however, it is advantageous to have the embossing and welding of the tracks in one System to be carried out directly one after the other, since this involves the difficulties of synchronization are lower than with pre-embossed, delivered and outsourced nonwovens. at the direct series connection of fleece production and the invention Further processing must be ensured that the production speeds the manufacture of the fleece and the further processing can be coordinated. Furthermore, depending on the number of layers, the appropriate ones are used for the production of the fleece Facilities required to reach the necessary locations.

Es ist schließlich auch möglich, bereits vom Vlieshersteller geprägtes, heißversiegeltes Vlies aufgespult an den Weiterverarbeiter zu liefern. Dieser spart in diesem Fall die Prägestufe. ;denn die erfindungsgemäßen Elemente z. B. zu Behältern oder dergl. weiterverarbeitet werden sollen, können Knickkanten bereits mit eingeprägt werden.Finally, it is also possible to to deliver heat-sealed fleece wound to the processor. This saves in this case the embossing step. because the elements according to the invention z. B. to containers or the like. To be processed further, creases can already be embossed will.
