  Isolierhülse mit veränderlichem Durchmesser aus Hartpapier und Verfahren zur Herstellung derselben.

   Durch die vorliegende Erfindung ist es möglich, das wegen seiner Isolierfestigkeit geschätzte Hartpapier in der gewünschten geringen Dicke zu entsprechend billigem Preise in guter Qualität herzustellen und zu verwenden, und zwar geschieht die Anwendung beispielsweise für die eingangs erwähnte Isolierung zweier Elemente eines Transformators durch Zwischenstellen zwischen dieselben entweder   so,   dass einer der aufgeschnittenen Rohrkörper auf einen kleineren Krümmungsradius zusammengedrückt wird, um die beiden Schnittränder zur gegenseitigen Überlappung zu bringen, was die dem Rohrkörper eigene Federung sehr wohl zulässt, oder so, dass zwei oder je nach der Spannung mehr Rohrkörper koaxial derart ineinandergesteckt werden, dass die Längsschnittlinie des einen durch das Vollmaterial des nach innen oder aussen folgenden Rohrkprpers abgedeckt wird.

   



   Selbstverständlich eignet sich die vorliegende Erfindung nicht nur zur Isolierung in Transformatoren, sondern auch zur Isolierung bei Polkemen und dgl. sowie überhaupt für irgend welche Isolierzwecke auf elektrischem Gebiete. Anderenteils lassen sich die aufgeschnittenen dünnen und biegsamen Hülsen, obgleich auf einem Dorn von kreisförmigem Querschnitt hergestellt, auch zur Umkleidung von Schenkeln, Spulen usw. von anderer, z. B. polygonaler, ovaler, rechteckiger, quadratischer   Qucrschnittaform   anwenden. 



   PATENT-ANSPRÜCHE :
1.   Isoherhülse   mit veränderlichem Durchmesser aus Hartpapier, insbesondere zur Isolierung in Transformatoren, dadurch   gekennzeichnet, dass sie aus mindestens einem dünnwandigen,   der Länge nach aufgeschnittenen und genügend   stark federnden Rohrkörper   aus gewickelte Presspapier besteht, dessen Schnittränder unter entsprechender Verminderung des ursprünglichen Rohrdurchmessers zur gegenseitigen Überlappung gebracht werden können.

 EMI2.1
 



   The present invention makes it possible to produce and use the hard paper, valued for its insulating strength, in the desired small thickness at correspondingly cheap prices in good quality, for example for the insulation of two elements of a transformer mentioned at the beginning by means of intermediate points between them either in such a way that one of the cut pipe bodies is compressed to a smaller radius of curvature in order to bring the two cut edges to mutual overlap, which the springiness of the pipe body allows very well, or so that two or, depending on the tension, more pipe bodies are inserted coaxially into one another that the longitudinal cutting line of the one is covered by the solid material of the tubular body following inwards or outwards.

   



   Of course, the present invention is not only suitable for insulation in transformers, but also for insulation in Polkemen and the like. As well as for any insulating purposes in the electrical field. On the other hand, the sliced thin and flexible sleeves, although made on a mandrel of circular cross-section, can also be used to clad legs, coils, etc. from others, e.g. B. polygonal, oval, rectangular, square cross-sectional shape.



   PATENT CLAIMS:
1. Isoher sleeve with variable diameter made of hard paper, in particular for insulation in transformers, characterized in that it consists of at least one thin-walled, lengthwise cut and sufficiently resilient tubular body made of wound press paper, the edges of which are cut with a corresponding reduction in the original tube diameter for mutual overlap can be brought.

Claims (1)

2. Isolierhülse nach Anspruch l, dadurch gekennzeichnet, dass sie aus mehreren Rohr- körpern zusammengesetzt ist, die derart incmandergesteckt sind, dass ihre Schnittlinien am Umfang zueinander versetzt sind, ho dass der Schnitt jedes Rohrkörpers durch Vollmaterial eines anderen Rohrkörpers abgedeckt wird. 2. Insulating sleeve according to claim 1, characterized in that it is composed of several tubular bodies which are plugged in such a way that their cutting lines are offset from one another on the circumference, ho that the cut of each tubular body is covered by solid material from another tubular body. 3. Verfahren zur Herstellung der Isoherhülse nach Anspruch 1, dadurch gekennzeichnet, dass eine mit Klebstoff v@rsehene Pap@erbahn @n einer Wickelmaschine unter Zusammenkleben der einzelnen Wickelschlchten und unter Pressdruck aufgewickelt und jeweils nach Vereinigung semer bestimmten Anzahl Wickelachichten zu einem Rohrkörper eine klebstoffreie Trennungs- bahn nut einlaufen gelassen wird, um ewe Scheidung der einzelnen ineinanderliegenden Rohrkörper zu erhalten, worauf nach Erkalten das ganzen Wickels dieser der Länge nach aufgeschnitten wird und die Rohrkörper an den Trennungssbahnen vonemander gelöst werden. 3. A method for the production of the insulating sleeve according to claim 1, characterized in that an adhesive provided with pap @ erbahn @n a winding machine with gluing together the individual winding layers and under pressure and each after combining its certain number of winding layers to form a tube body an adhesive-free Separation sheet is allowed to run in groove in order to obtain a separation of the individual tube bodies lying one inside the other, whereupon after cooling the whole coil of this is cut lengthwise and the tube bodies are detached from one another at the separation sheets.
