Description
)ie beweglichen mehradrigen elektrischen Leitungen und Kabel weisen einen die Adern umhüllenden Mantel aus Gummi oder Kunststoff auf. Erfahrungsgemäß sind diese Leitungen und Kal>el dann ausreichend flexibel, wenn ihre Adern in dem Mantel 5 schlüpfen können. Um diesen Schlupf zu sichern, darf eine Trennschicht, z. B. ein Film gemäß VDE- \rorschrift 0283, unter' dem Mantel liegen. Diese Trennschicht wird auch zuweilen z. B. aus Talkum hergestellt. Sie hat sich aber nicht bewährt, weil sie meist zu dünn ist. Sie wird nämlich bisher in folgender Weise erzeugt:The movable multi-core electrical lines and cables have a sheath made of rubber or plastic that surrounds the cores. Experience has shown that these lines and cables are sufficiently flexible when their cores can slip into the jacket 5. In order to secure this slip, a separating layer, e.g. B. a film according to VDE \ r regulation 0283, under 'the coat. This separating layer is also sometimes used, for. B. made of talc. But it has not proven itself because it is usually too thin. This is because it has so far been generated in the following way:
Die aus den verseilten Adern bestehende Kabelseele wird durch einen mit Talkum gefüllten Behälter hindurchgezogen, der in einem gewissen Abstand vor der Schneckenpresse angeordnet ist. Die Adern werden beim Durchgang durch diesen Behälter mit einer dünnen Talkumschicht bedeckt, die infolge der unvermeidlichen Bewegungen zum Teil wieder abfällt, l>evor die Kabelseele in die Schneckenpresse einläuft. Verständlicherweise haben dann die Adern in dem Mantel der fertigen Leitung nicht den ausreichenden Schlupf. Der Mantel läßt sich außerdem am Ende der Leitung nur schwer abstreifen, wenn die Adern zu Montagezwecken freigelegt werden sollen.The cable core consisting of the stranded cores is pulled through a container filled with talc, the at a certain distance in front of the Screw press is arranged. The veins will when passing through this container covered with a thin layer of talc, which as a result of the inevitable Movements partially drops again before the cable core runs into the screw press. Understandably, the cores in the sheath of the finished cable then do not have the adequate one Slip. The sheath is also difficult to strip off at the end of the cable if the wires are closed Should be exposed for assembly purposes.
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Bepuderung der Kabelseele bei der Herstellung von beweglichen mehradrigen Leitungen, deren mit Puderniittel bedeckte Adern einen ausreichenden Schlupf in der Mantelhülle zulassen. Erfindungsgemäß wird das dadurch erreicht, daß die in den Fuderbehälter eingeführte Kabelseele diesen erst am Pressenkopf verläßt, in dem die Ummantelung gebildet wird. Dieser Gedanke läßt sich dadurch verwirklichen, daß der Raum in der Schneckenpresse zwischen dem Presseneingang und dem Pressenkopf als Puderl>ehälter ausgeführt wird, dem das Pudermiitel zwischen dem Presseneingang und dem Pressenkopf oder vor dem Presseneingang zugeführt wird. toThe invention relates to a method and a device for powdering the cable core in the Manufacture of flexible multi-core cables, the cores of which are covered with powdered agent, have sufficient cores Allow slippage in the jacket shell. According to the invention this is achieved in that the in The cable core introduced into the feed container leaves it only at the press head in which the sheathing is formed. This idea can be realized by the fact that the space in the screw press between the press inlet and the press head is designed as a powder container to which the powder container between the press inlet and the press head or in front of the press inlet will. to
Die Zeichnung dient zur Erläuterung. Sie zeigt einen Schnitt durch die Schneckenpresse mit der hindurehlaufenden Kai>elseele.
