Description
Die Erfindung bezieht sich auf eine rollbare Wärmeijämmbahn nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a rollable thermal jam sheet according to the preamble of the claim 1.
Bereits bekannte rnllbare Wannedämmbahnen wurden in eic. Weise hergestellt, daß vorher einzeln angefertigte Abschnitte einer Hartschaumstoffplatte nebeneinander auf eine Kaschierungsbahn aufgeklebt wurden. Diese Art der Herstellung ermöglicht es /war. Spalte /wischen den ein/einen Abschnitten des Hartschaumstoffkörpers /u vermeiden und beim Verlegen der in eine Ebene abgerollten Bahn eine praktisch ununterbrochene Dämmstoffschicht /u erhalten. Andererseits ist die getrennte Herstellung der ein/einen Abschnitte des Hartschaumstoffkörpers, das Aufbringen einer Klebstoffschicht auf die Kaschierung und das Ausrichten der Abschnitte des Hartschaumstoffkörpers auf dieser umständlich und zeitraubend.Well-known rollable tub insulation sheets were used in eic. Way made that previously individually Manufactured sections of a rigid foam board glued next to one another on a liner became. This type of production makes it possible / was. Column / wipe the one / a section of the Avoid rigid foam body / u and a practical one when laying the web unrolled in a plane uninterrupted insulation layer / u obtained. on the other hand is the separate production of one / a section of the rigid foam body, the application an adhesive layer on the liner and the alignment of the sections of the rigid foam body on this cumbersome and time consuming.
Es ist ferner bekannt, eine größere Hartschaumstoffplatte auf die Kaschiemngsbahn aufzukleben und — da das spanlose Einschneiden von Hartschaumstoff wegen des Festklemmens eines flachen Schneidmessers mit nach dem bisherigen Stand der Technik noch nicht überwundenen Schwierigkeiten verbunden war — durch Einsägen in ein/eine Abschnitte zu zerteilen. Weiter sind Hartschaumstoffplatten bekannt, deren Hartschaumstoffkörper durch Aufschäumen unmittelbar auf die Kaschierung aufgebracht ist. Auch diese können zur Herstellung einer rollbaren Wärmcdämmbahn durch Einsägen des beispielsweise aus Polyurethan bestehenden Hartschaumsloffkörpers bis auf die Kaschierung oder, soweit der Hartschaumstoffkörper aus einem stark bröckelnden Material wie Polystyrol besteht, durch Trennung mit Hilfe von Hit/drähtcn abschnittsweise unterteilt werden. Beide IJntertcilungsarti'ii führen jcdodi zur Entstehung eines Spaltes an den I rennstellen. line Trennung durch Einsägen ist außerdem mn Spanbildiing verbunden. Schnitlvcrluslc sollen aber ui-gen der hohen Kosten des Rohmaterials von ll.imdi.itimen möglichst vermieden werden.It is also known to use a larger rigid foam board to stick on the lamination and - because of the non-cutting cutting of rigid foam the clamping of a flat cutting knife with the prior art not yet difficulties overcome - to be cut into sections by sawing. Rigid foam panels are also known whose rigid foam bodies are foamed directly is applied to the lamination. These can also be used to produce a rollable thermal insulation sheet by sawing the rigid foam body made of polyurethane, for example, down to the lamination or, if the rigid foam body is made of a highly crumbling material such as polystyrene can be divided into sections by separating them with the help of Hit / Wirhtcn. Both types of division lead jcdodi to the formation of a gap on the I run. line separation by sawing is also associated with chip formation. Cutlvcrluslc but should ui-gen the high cost of the raw material should be avoided as far as possible by ll.imdi.itimen.
Der Erfindung liegt die Aufgabe zugrunde, eine rollbare Wärmedämmbahn, die Wärmeverluste durch einen Spalt vermeidet, zu schaffen, die einfacher und wirtschaftlicher herstellbar ist als es nach dem bisherigen Stande der Technik möglich war.The invention is based on the object of a rollable thermal insulation sheet that prevents heat losses avoids creating a gap that is easier and more economical to manufacture than it is after prior art was possible.
Ein geeignetes Mittel hierzu ist die Schneidvorrichtung nach dem Hauptpatent 24 08 319.A suitable means for this is the cutting device according to the main patent 24 08 319.
Unter Ausnutzung dieses Mittels besteht die Lösung der Aufgabe enindungsgemäß in einer der eingangsBy utilizing this means, the object is achieved according to the invention in one of the above
ίο genannten Gattung entsprechenden rollbaren Wärmedämmbahn, deren Hartschaumstoffkörper durch unmittelbares Aufschäumen fest mit der Kaschierung verbunden ist.ίο the mentioned category corresponding rollable thermal insulation membrane, their rigid foam body by direct foaming firmly with the lamination connected is.
Durch diese Lösung wird erreicht, daß der Hartschaumstoffkörper der rollbaren Wärmedämmbahn, obwohl er vor seiner Unterteilung durch bis auf die Kaschierung geführte Einschnitte als Hartschaumstoffplatte oder -bahn unmittelbar auf die KaschierungsL- .an aufgebracht ist. keine spanbildenden Trennvorgänge erfordert und nach dem Verlegen in einer Ebene eine in sich geschlossene Wärmedämmschicht bildet.This solution ensures that the rigid foam body the rollable thermal insulation membrane, although it is before its subdivision by up to the Lamination made incisions as a rigid foam sheet or sheet directly on the lamination is upset. does not require any chip-forming cutting processes and after laying in one level an in closed thermal insulation layer is formed.

Ferner kann zwischen dem Hartschaumstoffkörper und der feuchtigkeitsdichten Kaschierung eine mit Perforationen versehene Trennschicht angeordnet sein, so daß der Hartschaumstoffkörper nur im Bereich der Perforationen unmittelbar an der Kaschieriing festhaftet. Dadurch wird erreicht, daß in dem labyrinthartigen Gebiet, wo sich die beispielsweise ans Papier bestehende Trennschicht befindet, /.wischen dem Hartschaunisloffkörper und der feuchtigkeitsdichten Kaschierung keine unmittelbare Verbindung, sondern ein Druckausgleichsraum gebildet wird, durch den verdampfende Feuchtigkeit bei Überdruck nach außen abgeführt werden kann, während die unmittelbare feste Verbindung lies Hartschaumstoffkörpcrs in den Perforationsbereichen mit der feuchtigkeitsdichten Kaschieriing einen festen Halt der feuchtigkeitsdichten Kaschierung an dem I lartschaumstoffkörper gewährleistet.Furthermore, a with Perforations provided separating layer be arranged so that the rigid foam body only in the area of Perforations adhered directly to the laminating ring. It is thereby achieved that in the labyrinth-like area where the for example existing on paper Separating layer is located /. Between the Hartschaunisloff body and the moisture-proof lining no direct connection, but a pressure equalization space is formed, by which evaporating moisture is discharged to the outside at overpressure can be while the immediate permanent connection read rigid foam bodies in the perforation areas with the moisture-proof lamination ensures a firm hold of the moisture-proof lining on the rigid foam body.
Besonders vorteilhaft ist dabei eine solche Verteilung der Perforationen, daß die Bereiche beider Seitenrander der Rollbahnen von Perforationen frei bleiben. Dadurch wird erreicht, daß beim Nebeneinandcrverlegen rollbarer Wärmedämmbahnen der zur Rede stehenden Art unter Verklebung des jeweils überstehenden Scitenrandes der Kaschierung der einen Rollbahn mit der Kaschierung der benachbarten Rollbahn die Kräfte beim temperaturabhängigen Zusammenziehen der Bahnen sich über die Strecke zwischen jeweils zweiSuch a distribution is particularly advantageous the perforations that the areas of both side edges of the runways remain free of perforations. Through this it is achieved that when laying rollable thermal insulation sheets of the type in question while gluing the protruding Scitenrand of the lamination of one of the runway with the Lamination of the adjacent runway reduces the forces when the temperature-dependent contraction of the Orbit themselves over the distance between each two

This applies in particular to roller tracks laminated with plastic films, which is a special have strong temperature dependence and are prone to cracking in the event of strong temperature fluctuations
