Die Erfindung betrifft «in Verfahren zur Herstellung von wärme isolierend en Schalen, die z.B. zur Wärmeisolierung von Rohrleitungen dienen. Solche Schalen werden seist in der Weise gefertigt* daß das laolationsaaterial gegebenenfalls mit Bindemittel gemischt au Blöcken gegossen oder gepreßt und dann die Blöcke zu Schalen oder Segaenten verarbeitet werden, deren Innenform mit dem Profil der zu isolierenden Röhre übereinstimmt. Darauf werden die Schalen zu längeren oder kursieren Stücken geschnitten.The invention relates to methods of manufacture of heat insulating shells, e.g. for heat insulation serve of pipelines. Such shells are made in such a way that the laolationsaaterial, if necessary mixed with binding agent, poured or pressed into blocks and then processed into shells or segments whose inner shape matches the profile of the pipe to be insulated. Then the bowls become longer or circulate pieces cut.
Semäu einem anderen Verfahren werden Decken aus Mineral« wolle um einen Dorn gewickelt, wobei zwischen den Schichten Bindemittel zugesetzt wird. Das entstandene röhrenförmige Gebilde wird dann der Lange nach durchgeschnitten.Another method is to use mineral blankets " wool wrapped around a thorn, being between the layers Binder is added. The resulting tubular The structure is then cut lengthways.
Hs ist auch bekannt, Ieoliermasse in Rohrform zu gießen und hernach das Rohr der Länge nach zu zersägen.Hs is also known to pour oleoling compound in pipe form and afterwards to saw the pipe lengthways.

Bei den bekannten Verfahren zur Herstellung von Isolier« schalen treten in vielen Fällen große Mengen Abfälle auf, stets ist das Anbringen der Schalen und Fertigmachen der unter deren Verwendung zu schaffenden Isolierung uaständlioh und stark arbeitsaufwendig. Dazu koaat nooh, daS man bei der Schalenheretellung nicht frei 1st in der wahl des isolieren« den Materials. Ferner besitzt das verwendete Bindemittel nur eine beschränkte Temperaturbeständigkeit, welche natur» gemäß das Verwendungsgebiet der /Schalen einschränkt, außerdea auch die Isolierfähigkeit der Sohaien.In the known processes for the production of insulating shells, large amounts of waste occur in many cases. It is always necessary to attach the shells and prepare the insulation to be created using them and heavily labor intensive. In addition, no one is free to choose the isolate when making the shell " the material. Furthermore, the binder used has only a limited temperature resistance, which is naturally » according to the area of use of the trays, besides dea also the isolation ability of the Sohaien.
lie Erfindung bezweckt die Schaffung von Isolierschalen, die für ihre Herstellung jedes Isoliermaterial verwenden lassen und bei ihrer Verwendung Zeit- und Arbeitsersparnis vermitteln und Isolierungen hoher Wirksamkeit und Temperatur« bestandigkeit fertigen lassen.lie invention aims to create insulating shells, which can use any insulation material for their production and save time and labor when using them and have insulation made with high effectiveness and temperature resistance.
Das neue Verfahren der Herstellung von Isolierschalen ist dadurch gekennzeichnet, daß eine Bahn aus natürlichen, synthetischen oder mineralischen Fasern mit eines Bindemit« tel getränkt und an einer seiner Oberflächen mit einer qohiaht aus biegsamem oder/und elastischem isolierenden Ma« terial bedeckt und dann beide Schichten mit der getränkten Schicht außenllegend zusammen um einen Born gelegt in eine 909842/1303 BAD °'^The new method of manufacturing insulating shells is characterized in that a web of natural, synthetic or mineral fibers is impregnated with a binding agent and covered on one of its surfaces with a layer of flexible and / or elastic insulating material and then both layers with the soaked layer lying on the outside together around a well in a 909842/1303 BAD ° '^

It is possible to use any flexible and / or flexible material that has insulating properties on it for the inside of the shells. For example, mineral wool deoks and other cheap insulating materials can be used for the inside of the sole. For the outside "eohale, which thus becomes stable during the hardening process and keeps its shape", glass fabric or oleiferous mat can be used in some cases. These materials can be a binder such as a hot or cold curable plastic. a suitable plastic preparation ( a ·· liquid thermoplastic, bitumen, etc.).
