Description

Biegsame elektrische Heizleitung Häufig werden biegsame Heizleiter gebraucht, die sich vorgegebenen Profilen leicht anpassen, wie z. B. bei der Beheizung der Kanten von Luftschrauben zur Verhinderung des Eisansatzes.Flexible electrical heating cables Flexible heating conductors are often used used, the given profiles easily adapt, such. B. in heating the edges of propellers to prevent ice accumulation.

Es ist -zwar schon bekannt, eine wärmebeständige Isolation in der Weise herzustellen, daß Leitungsdrähte mit anorganischen Stoffen, wie Glas oder Erdalkalioxyden, in Metallrohre eingeschlossen und durch Ziehen der Rohre der anorganische Füllstoff verdichtet wird. Derartige Heizleiter sind aber starr und lassen sich nur schwer biegen.It is already known that there is a heat-resistant insulation in the Way to manufacture that lead wires with inorganic materials, such as glass or Alkaline earth oxides, enclosed in metal pipes and made inorganic by pulling the pipes Filler is compacted. Such heating conductors are rigid and can be difficult to bend.

Gemäß der Erfindung werden :die Heizleiter mit einem feuerfesten, elektrisch isolierenden, zweckmäßig anorganischen Faserstoff, wie Glasseide, Schlackenwolle od. dgl., umsponnen oder umflochten, und auf diese Isolierschicht wird eine zweite, leicht biegsame metallische Schicht, z. B. durch Umspinnen oder Umflechten mit einem Metalldraht, aufgebracht.According to the invention: the heating conductors with a fireproof, electrically insulating, expediently inorganic fiber material, such as glass silk, slag wool or the like, wrapped or braided, and a second, slightly flexible metallic layer, e.g. B. by spinning or braiding with a Metal wire, applied.

Diese Leitungen können dadurch feuchtigkeitsfest gemacht werden, daß sie z. B. im Durchziehverfahren mit einem geschmolzenen Metall oder mit einem wärmebeständigen Lack oder Kunststoffilm überzogen werden. Auch ist es zuweilen zweckmäßig, den ersten Überzug des Heizleiters mit dem anorganischen Faserstoff schon vor der metallischen Umspinnung mit einem wärmebeständigen Lack zu überziehen oder mit einer Folie zu umgeben.These lines can be made moisture-proof in that she z. B. in the pull-through process with a molten metal or with a heat-resistant one Paint or plastic film are coated. Sometimes it is also useful to do the first Coating of the heating conductor with the inorganic fiber material before the metallic one Covering the wrapping with a heat-resistant lacquer or with a foil surround.

Die Heizleiter gemäß der Erfindung werden z. B. wie folgt verwendet. Eine Luftschraube aus Holz hat an der Kante eine Einsenkung, in die der Heizleiter eingelegt und z. B. durch eine metallische Abdeckung in seiner Lage gehalten wird. In Metallschrauben können die Heizleiter gemäß der Erfindung in entsprechende Nuten mit Metall eingegossen werden.The heating conductors according to the invention are z. B. used as follows. A wooden propeller has a recess on the edge into which the heating conductor inserted and z. B. by a metallic Cover in its location is held. In metal screws, the heating conductors according to the invention can be converted into corresponding Grooves are cast in with metal.

PATENTANSPRUCH: Biegsame elektrische Heizleitung, dadurch gekennzeichnet, daß auf den Heizleiter eine elektrische Isolierung aus einem wärmebeständigen Stoff, wie Glasseide, Schlackenwolle od. dgl., aufgesponnen oder aufgeflochten, diese Isolierung gegebenenfalls mit wärmebeständigen Lacken od. dgl. getränkt und über der elektrischen Isolierung eine metallische Umspinnung oder Umflechtung angebracht ist, die gegebenenfalls durch einen weiteren Überzug feuchtigkeitsundurchlässig gestaltet wird, derart, daß sie biegsam bleibt.PATENT CLAIM: Flexible electrical heating cable, characterized in that that on the heating conductor an electrical insulation made of a heat-resistant material, such as fiberglass, slag wool or the like, spun or braided, this insulation if necessary with heat-resistant varnishes or the like. Impregnated and over the electrical Insulation a metallic wrapping or braiding is attached, if necessary is made moisture-impermeable by a further coating, in such a way that that it remains pliable.
