Abstract
Description
Verfahren zum kontinuierlichen Herstellen eines flächenhaften Gegenstands mit kammer- bzw. kanalartigen Hohlräumen Die Erfindung betrifft ein Verfahren zum kontinuierlichen Herstellen eines flächenhaften Gegenstands aus mindestens zwei Materialbairnen mit zwischen den Materialbahnen angeordneten kammer- bzw. kanalartigen Hohlräumen.Process for the continuous production of a sheet-like object with chamber-like or channel-like cavities The invention relates to a method for continuous production of a flat object from at least two Material bairnen with chamber-like or channel-like arranged between the material webs Cavities.
Es ist bekannt, zwei Materialbahnen an bestimmten Stellen derart miteinander zu verbinden, daß Hohlräume zwischen den Bahnen entstehen, indem die Bahnen nur an bestimmten Stellen unten Druckanwendung miteinander verbunden werden, beispielsweise durch Verschweißen, Heißsiegeln oder Verkleben. Diese bekannten Methoden haben den Nachteil, daß die Druckanwendung nicht auf der gesamten Bahnenfläche erfolgen kann, sondern nur an bestimmten Stellen ausgeiibt werden darf, wozu aufwendige Vorrichtungen und erheblicher Arbeitsaufwand erforderlich sind. Besonders schlecht eignen sich die bekannten Methoden für kontinuierliche Herstellungsverfahren. Sie sind auch wenig anpassungsfähig und variabel und bereiten insbesondere bei komplizierten Hohlrau:r-£mustern große Schwierlgkeiten, Ziel der Erfindung istsdaher die Schaffung eines #erfahrens, welches die erwähnten Nachteile nicht aufweist, besonders einfach ist, die Herstellung aller, auch der kompliziertesten Kammerstrukturen zuläßt und vorzüglich zur kontinuierlichen Durchführung geeignet ist.It is known to interconnect two webs of material at certain points in this way to connect that voids between the webs are created by the webs only at certain points below pressure application are connected to each other, for example by welding, heat sealing or gluing. These known methods have the Disadvantage that pressure cannot be applied to the entire surface of the web, but may only be issued at certain points, including expensive devices and considerable work is required. Are particularly bad the known methods for continuous manufacturing processes. You are too Little adaptable and variable and prepare especially with complicated hollow spaces: r- £ patterns great difficulties, The invention therefore aims to provide a #procedure that does not have the disadvantages mentioned is particularly simple is, allows the production of all, even the most complex chamber structures and is particularly suitable for continuous implementation.
Das erfindungsgemäße Verfahren zum kontinuierlichen 11erstellen eines flächenhaften Gegenstandes mit kammer- bzw.The inventive method for continuously creating a flat object with chamber or
kanalartigen Hohlräumen besteht darin, daß auf mindestens eine Seite einer ersten Materialbahn ein Trennmittel an den den gewünschten Hohlräumen entsprechenden Stellen a;ufgebracht und dann diese Seite nach an sich bekannten Methoden mit einer zweiten Materialbahn, die unter den Kaschierungsbedingungen an den trennmittelhaltigen Stellen keine stoffschlüssige Verbindung mit der ersten Bahn eingeht, kaschiert wird und gegebenenfalls anschließend die Hohlräume durch Eindrücken eines Fluids aufgeweitet werden.channel-like cavities consists in that on at least one side a first material web a separating agent at the corresponding to the desired cavities Set up and then this page using methods known per se with a second material web, which under the lamination conditions on the release agent-containing Make no material connection with the first membrane, laminated is and optionally then the cavities by pressing in a fluid be widened.
Man erhält auf diese Weise verbundbahnen, die nur an den trennmittelfreien Stellen stoffschlüssig miteinander verbunden sind. Die erfindungsgemäß erhältlichen, flächenhaften Gegenstände bestehen aus mindestens zwei Material bahnen. Sie können aber auch aus drei oder mehr Materialbahnen aufgebaut sein. So kann auf eine Materialbahn beidseitig Trennmittal aufgebracht werden und dann beiiseitig eine Kaschierung mit zwei weiteren Bahnen, die ihrerseits entweder gleich oder verschieden sein können, erfolgen.In this way, composite webs are obtained that only apply to the release agent-free Places are firmly connected to each other. The inventively obtainable, Flat objects consist of at least two material webs. You can but also be made up of three or more webs of material. So can on a web of material A separating medium can be applied on both sides and then a lamination with on both sides two further tracks, which in turn can either be the same or different, take place.
Die im erfindungsgemäßen Verfahren verwendeten Bahnen können aus beliebigen Materialien bestehen. Vorzugsweise werden Kunststoffbahnen verwendet, insbesondere solche aus thermoplastischen, heißsiege#baren #jrnststoffen oder mit solchen beschichtete, nicht thermor,lastische FlächenOebilde wie z.B. kunststoffbeschichtete Textilien, Papier und dergl. Sehr geeignet sind auch verstärkte Kunststoffbahnen, bei denen die Verstärkung z.3. aus Gewebe-, Papier-oder etalloahnen besteht. Die Bahnen können aber auch aus Metallbahnen bestehen. Besonders interessante Anwendungsmöglichkeiten ergeben sich dann, wenn eine der Materialoahnen aus einer Metallfolie oder -platte--besteht.The webs used in the method according to the invention can be made of any Materials exist. Plastic sheets are preferably used, in particular those made of thermoplastic, heat-sealable plastics or those coated with such, non-thermal, elastic surfaces such as plastic-coated textiles, Paper and The like. Reinforced plastic sheets are also very suitable, where the reinforcement z.3. consists of fabric, paper or etalloahnen. the However, tracks can also consist of metal tracks. Particularly interesting application possibilities arise when one of the material elements consists of a metal foil or plate.
Im allgemeinen werden flexible Bahnen verwendet. Es ist aber auch möglich, daß wenigstens eine der Bahnen aus einer starren Materialplatte besteht. Es ist auch möglich, mehr als eine Platte erfindungsgemäß zu einem flächenhaften Gegenstand mit Hohlräumen zu verbinden, indem zwischen je zwei Materialplatten eine flexible Folie einkaschiert wird, die vorzugsweise beidseitig ein Trennmittelmuster trägt.Flexible sheets are generally used. It is also possible that at least one of the tracks consists of a rigid sheet of material. It is also possible, according to the invention, to form a sheet-like panel with more than one panel To connect the object with cavities by placing a flexible film is laminated, which preferably has a separating agent pattern on both sides wearing.
Als Trennmittel werden erfindungsgemäß Substanzen verwendet, die unter den angewandten Kaschierungsbedingungen das Entstehen einer stoffschlüssigen Verbindung zwischen den Materialbahnen an den Stellen verhindern, welche das Treimmittel tragen. Zweckmäßig soll das Trennmittel unter den angewandten Druckbedingungen zwischen den beiden: Material bahnen nicht "wandern, um eine genaue Einhaltung des gewünschten Verbindungsmusters sicherzustellen. Für besondere Zwecke, z.B. bei Dekofolien, kann aber eine solche Wanderung auch erwünscht sein.According to the invention, substances are used as release agents which are listed under the lamination conditions used, the creation of a cohesive connection Prevent between the material webs at the points that carry the trimming means. The release agent should expediently be between the two: Material does not pave the way to exact compliance with the desired Ensure connection pattern. For special purposes, e.g. for decorative foils, but such a hike may also be desirable.
Welche Trennmittel geeignet sind, hängt vom Material der miteinander zu verbindenden Bahnen ab. Werden Bahnen aus gleichem Material miteinander kaschiert, so wird das Trennmittel mit keiner der beiden Bahnen eine stoffschlüssige Verbindung eingehen. Werden Bahnen aus unterschiedlichem Material miteinander kaschiert, so genügt es, wenn das Trennmittel nur mit einer der beiden Bahnen keine oder eine leicht lösbare Verbindung eingeht. Beispiele für erfolgreich verwendete Trennmittel sind Polyvinylalkohol, Polyäthylen, Polytetrafluoräthylen, Polychlortrifluoräthylen, Polyamide, Methylcellulose, Silicone, Wachse, Polyvinylchlorid, Puder und Celluloseester.Which release agents are suitable depends on the material used with each other to be connected. If sheets of the same material are laminated together, so the release agent does not form a material bond with either of the two webs enter. If sheets of different material are laminated together, so it is sufficient if the release agent does not or only with one of the two tracks one enters into an easily detachable connection. Examples of successfully used release agents are polyvinyl alcohol, polyethylene, polytetrafluoroethylene, polychlorotrifluoroethylene, Polyamides, methyl cellulose, silicones, waxes, polyvinyl chloride, powders and cellulose esters.
