Description

Kunststoffschaumbahnen und/oder -platten wurden für verschiedenste Zwecke benötigt. Einsatzbereiche können sein: Verpackung, Isolierung. Wie bei der Verpackung, so kann auch für Isolierungszwecke eine besonders gestaltete Schaumstoffoberfläche von Vorteil sein. Bei der Verpackung dient die besonders geformte Schaumstoffoberfläche dazu, den Schaumstoff an unregelmäßige Verpackungsoberflächen anzupassen. Bei der Isolierung kann eine mit Erhebungen und/oder Vertiefungen versehene Schaumstoffoberfläche verschiedenste Zwecke erfüllen. Ein Zweck kann die Bildung von Luftpolstern sein. Ein anderer Zweck kann eine Dränage sein.Plastic foam sheets and / or sheets have been used for a wide variety of purposes Purposes needed. Areas of application can be: packaging, Insulation. As with packaging, so can for Isolation purposes a specially designed foam surface be an advantage. The packaging is used for specially shaped foam surface, the foam to adapt to irregular packaging surfaces. At the insulation can be one with elevations and / or depressions provided foam surface serve a variety of purposes. A purpose can be the formation of air cushions. A other purpose can be a drainage.

Es ist bislang aufwendig, derartige Schaumstoffflächen in kontinuierlichem Herstellungsgang darzustellen. Diese kontinuierlichen Herstellungsvorgänge sind technisch zwar leichter, jedoch noch unwirtschaftlicher.It has so far been complex to have such foam surfaces in to represent a continuous production process. This continuous Manufacturing processes are technically easier, however, even more uneconomical.

Ein bekanntes Verfahren sieht vor, in die kontinuierlich hergestellten Bahnen Nuten einzufräsen. Das Einfräsen der Nuten bedingt einen aufwendigen Vorgang mit entsprechendem Materialverlust.A known method provides for continuous milled grooves. Milling the Grooving requires a complex process with the corresponding Loss of material.

Der Erfindung liegt die Aufgabe zugrunde, die Herstellung solcher Kunststoffschaumbahnen und/oder -platten zu vereinfachen. Nach der Erfindung wird das dadurch erreicht, daß bei der Extrusion des Kunststoffschaumes eine Ringdüse eingesetzt wird, die innen und/oder außen die der gewünschten Profilierung entsprechenden Ausnehmungen und/oder Ausformungen aufweist. Das so entstehende Kunststoffrohr bzw. der Kunststoffschlauch wird nach der Extrusion aufgeschnitten und zu der vorgesehenen Bahn oder Platte ausgebreitet. Das Aufschneiden erfolgt vorzugsweise bevor der Kunststoffschaum seine Elastizität vollständig verliert, d. h. bevor der Kunststoffschaum in der Ringform Rückstellkräfte entwickelt, die verhindern, daß sich das Material nach dem Aufschneiden sauber (gleichmäßig) auf ein dazu vorgesehenes Band auflegt.The invention has for its object the manufacture to simplify such plastic foam sheets and / or sheets. According to the invention this is achieved in that an extrusion of the plastic foam used an annular die the inside and / or outside of the desired profiling has corresponding recesses and / or formations. The resulting plastic pipe or plastic hose is cut open after extrusion and closed  the intended path or plate spread. The slicing is preferably done before the plastic foam completely loses its elasticity, d. H. before the Plastic foam in the ring shape developed restoring forces, which prevent the material from being cut open place it cleanly (evenly) on a dedicated tape.

Wahlweise wird der Kunststoffschaum nach dem Schlitzen an der profilierten Oberfläche mit einem Vlies kaschiert. Mit dem Vlies und mit den Ausnehmungen eignet sich der Kunststoffschaum hervorragend für eine Isolierung und Dränage im Kellerbereich/Fundamentbereich von Gebäuden. Das Vlies kann beim Kaschieren so bemessen sein, daß seine Ränder seitlich gegenüber dem Schaum vorstehen.Optionally, the plastic foam after slitting the profiled surface laminated with a fleece. With the Non-woven and with the recesses, the plastic foam is suitable excellent for insulation and drainage in the Basement area / foundation area of buildings. The fleece can When laminating, be dimensioned so that its edges are on the side protrude towards the foam.

Der so entstandene Schaum wird in bestimmte Längen unterteilt, z. B. in Platten mit 1,25 m Länge. Wahlweise wird ein Plattenende zugleich durch Formfräsung mit einem Anschlußprofil versehen. Das Anschlußprofil kann z. B. dem Anschluß an ein Dränagerohr und/oder der Verbindung der Platten untereinander dienen.The resulting foam is divided into certain lengths, e.g. B. in plates with a length of 1.25 m. Optionally, a Panel end at the same time by form milling with a connection profile Mistake. The connection profile can, for. B. the connection to a drainage pipe and / or the connection of the plates serve one another.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing is an embodiment of the invention shown.

Mit 1 ist ein Extruder bezeichnet, der ein Einspindelextruder oder ein Mehrspindelextruder ist. In dem Extruder 1 wird Kunststoffmaterial, z. B. Polyethylen oder Polyurethan oder Polystyrol oder Polypropylen oder Mischungen davon, plastizifiert und geschäumt. Der Schäumvorgang kann sich bis in eine nachgeschaltete Düse 2 oder darüber hinaus erstrecken. Der Schäumvorgang kann auch erst in der Düse 2 beginnen. Der Schäumvorgang wird durch ein Treibmittel ausgelöst, welches den Kunststoff vor dem Eintritt in den Extruder oder gleichzeitig mit dem Eintritt oder auch einige Zeit nach dem Eintritt in den Extruder beigemengt wird. Das Treibmittel kann eine feste Konsistenz haben. Es kann aber auch flüssig oder gasförmig sein. Das Treibmittel entwickelt an der vorgesehenen Stelle Gas, welches eine vielzählige Schaumstoffstruktur verursacht. Die einzelnen Zellen des Schaumes sind je nach Beschaffenheit des Kunststoffes und/oder des Treibmittels offenzellig oder geschlossenzellig. 1 denotes an extruder which is a single-screw extruder or a multi-screw extruder. In the extruder 1 plastic material, for. B. polyethylene or polyurethane or polystyrene or polypropylene or mixtures thereof, plasticized and foamed. The foaming process can extend into a downstream nozzle 2 or beyond. The foaming process can also only begin in the nozzle 2 . The foaming process is triggered by a blowing agent, which is added to the plastic before it enters the extruder or at the same time as it enters, or even some time after it enters the extruder. The blowing agent can have a firm consistency. However, it can also be liquid or gaseous. The blowing agent develops gas at the intended location, which causes a multitude of foam structures. The individual cells of the foam are open-celled or closed-celled, depending on the nature of the plastic and / or the blowing agent.

Nach Fig. 1 ist die Extruderdüse 2 mit einem ringförmigen Schlitz 4 versehen, der vom äußeren Rand in radialer Richtung nach außen hin zahnartige Vergrößerungen 3 aufweist. Dies führt bei dem Extrusionsvorgang zu einem Schaumstoffrohr 5, welches an der Außenseite mit Stegen versehen ist, die sich in Längsrichtung es Schaumstoffrohres erstrecken.According to Fig. 1, the extruder die 2 is provided with an annular slot 4, which has the outer edge in the radial direction towards the outside tooth-like enlargements. 3 In the extrusion process, this leads to a foam tube 5 which is provided on the outside with webs which extend in the longitudinal direction of the foam tube.

Nach Fig. 1 wird das Schaumstoffrohr nach Verlassen der Extrusionsdüse 2 mit einem Messer 6 geschlitzt und zugleich zu einer Schaumstoffbahn 7 ausgebreitet. Die Stege liegen dabei an der Unterseite der Schaumstoffbahn.According to FIG. 1, the foam tube is slit with a knife 6 after leaving the extrusion nozzle 2 and at the same time spread out to form a foam web 7 . The webs are on the underside of the foam sheet.

Während nach Fig. 1 ein zahnartiges Schaumstoffprofil entstanden ist, ist nach Fig. 2 in einem Extrusionsvorgang ein Schaumstoffprofil entstanden, welches an der Oberfläche gewellt ist. Das Kunststoffprofil ist mit 11 bezeichnet.While according to Fig. 1, a tooth-like foam profile is formed, a foam profile is shown in FIG. 2 in an extrusion process emerged which is corrugated on the surface. The plastic profile is designated 11 .

Zugleich ist die Kunststoffschaumbahn so angeordnet, daß das Profil oben liegt. Dadurch ist das Aufkaschieren eines Vlieses 12 leichter. Das Vlies 12 wird von einer Rolle 13 abgezogen und mittels einer Andruckrolle 14 an die Kunststoffschaumbahn 10 angepreßt. Vorzugsweise geschieht das nach geringfügigem Anschmelzen der Oberfläche der Kunststoffschaumbahn 10. Das Anschmelzen kann mittels Heißluftgeräten oder auch mittels Wärmestrahlern bewirkt werden. Als Wärmestrahler eignen sich vor allem Intrarotstrahler.At the same time, the plastic foam sheet is arranged so that the profile is on top. This makes it easier to laminate a fleece 12 . The nonwoven fabric 12 is drawn from a roll 13 and pressed against the plastic foam strip 10 by means of a pressure roller fourteenth This is preferably done after the surface of the plastic foam sheet 10 has melted slightly. The melting can be effected by means of hot air devices or also by means of heat radiators. Infrared heaters are particularly suitable as heat radiators.

Die nach Fig. 2 vorgesehene Anordnung der Profilfläche 11 kann entweder dadurch erreicht werden, daß nach dem Aufschlitzen des Rohres eine Umlenkung der entstehenden Profilbahn um 180° erfolgt oder aber die Schlitzung von unten erfolgt und die durch Aufschlitzen entstehenden Seitenränder seitlich gelenkt werden. Die vorgesehene Anordnung kann aber auch dadurch entstehen, daß die Profilierung an der Rohrinnenseite vorgesehen ist und die Aufschlitzung gemäß Fig. 1 erfolgt.The arrangement of the profile surface 11 provided according to FIG. 2 can either be achieved in that after the tube is slit, the resulting profiled sheet is deflected by 180 ° or the slitting takes place from below and the side edges resulting from slitting are laterally directed. The proposed arrangement can, however, also result from the fact that the profiling is provided on the inside of the tube and the slitting takes place according to FIG .
