Description

Die neue Vorrichtung dient dazu, elektrische Kabel in bekannter Weise derart zu isolieren, daß zwischen der Metallader und dem Isoliermantel ein spiralig verlaufender Luftraum bestehen bleibt, dessen Abstand durch die Einlegung einer ebenfalls spiralig verlaufenden Schnur gesichert wird. Bei den bekannten Isolationen dieser Art besteht der Mantel aus einem flach geführten Band, dessenThe new device is used to supply electrical cables in a known manner isolate that between the metal wire and the insulating jacket a spiral Air space remains, the spacing of which is also spiraled by the insertion of a running cord is secured. In the case of the known insulation of this type, there is Coat made from a flat band, whose

ίο spiraliger Verlauf demjenigen der Schnur entgegengesetzt gerichtet ist. Die flache Auflagerung des Bandes bedingt eine Schraubenlinie mit verhältnismäßig geringer Steigung, so daß eine lange Naht entsteht. Die Länge der Naht ist aber gleichbedeutend mit der Anzahl von Fehlerquellen, und um diese Naht zu kürzen, ist der Erfindung gemäß eine Vorrichtung geschaffen, die das ummantelnde Band, nachdem die Stützschnur aufgebracht ist, in gerundeter Form umlegt; dabei entsteht dann eine sehr steile Naht, die dem entsprechend auch kurzer ausfällt.ίο spiral course that of the cord is directed in the opposite direction. The flat support of the tape requires a helical line with a relatively low slope, so that a long seam is created. The length But the seam is synonymous with the number of sources of error, and around this seam To shorten, the invention is provided according to a device that encapsulates After the support cord has been applied, the tape is wrapped in a rounded shape; thereby arises then a very steep seam, which is correspondingly shorter.

Die neue Vorrichtung besteht somit in dem Zusammenwirken der bekannten Schnurrolle und der in einem' Drehgestell untergebrachten Bandrolle, mit der Einrichtung eines die Rundung des Mantelbandes herbeiführenden Führungskörpers.The new device thus consists in the cooperation of the known line roller and the tape reel housed in a bogie, with the facility of a die Rounding of the jacket band causing the guide body.

In der Zeichnung ist diese X'Orrichtung dargestellt.In the drawing, this is the X 'direction shown.

Der Drehkörper α wird durch die Antriebsscheibe b in Drehung versetzt. Er enthält eine Rolle c,' welche den isolierenden Stoff, beispielsweise Papier, trägt, und einen Dorn d, durch den das blanke Kabel hindurchgeführt wird. Der isolierende Stoff, das Papier, wird durch einen Führungsring e (s. auch -Abb. 2) hindurchgeführt, der. mit dem Dorn d einen einzigen Körper bildet. Aus diesem Ring tritt der Isolationsstoff in die Öffnung f zwisehen dem Dorn d und der Matrize g ein. Es ist ferner hinter der Rolle c eine Spule h angeordnet, die eine Schnur enthält. Diese Schnur kann Papiergarn sein. Sie wird vonThe rotating body α is set in rotation by the drive pulley b. It contains a roll c, which carries the insulating material, for example paper, and a mandrel d through which the bare cable is passed. The insulating material, the paper, is passed through a guide ring e (see also -Fig. 2), the. forms a single body with the mandrel d. From this ring, the insulation material enters the opening f between the mandrel d and the die g . It is also arranged behind the roller c, a spool h which contains a cord. This cord can be paper thread. She is from

der Spule h spiralig um das blanke. Kabel gelegt, und demgemäß ist die Dufchlaßöffnung des Domes d so bemessen, daß das blanke Kabel mit der spiralig umlegten Schnur in ihr Raum findet. Es ist erkennbar, daß der durch die öffnung / aufgelegte Isoliermantel nicht unmittelbar auf das blanke Kabel zu liegen kommt, sondern daß zwischen beiden Teilen ein durch die Schnur abgestützter Höhlmantel entsteht, der infolge seiner Rundung nur eine verhältnismäßig kurze Naht bedingt.of the coil h spirally around the bare. Cable laid, and accordingly the Dufchlaßloch the dome d is dimensioned so that the bare cable with the spirally wrapped cord finds space in it. It can be seen that the insulating jacket placed through the opening does not come to rest directly on the bare cable, but that a hollow jacket is formed between the two parts, supported by the cord, which due to its rounding requires only a relatively short seam.

Die Spule h wird durch die Schnurscheibe i angetrieben und durch die Bremse k gebremst.The spool h is driven by the cord pulley i and braked by the brake k.
