Abstract

A cable is described which has a rodent protection layer between a plastic inner sheath (5) and a plastic outer sheath (9). This rodent protection layer consists of a strip of emery paper or abrasive cords. The strip (6) is fitted such that it runs longitudinally or in a helical shape with an overlap, the overlapping zone being bonded using an adhesive. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Kabel gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a cable according to the Preamble of the main claim.

Ein derartiges Kabel ist aus der DE-0S 35 02 042 bekannt. Das bekannte Kabel weist eine extrudierbare Kunststoffschicht auf, die mit Glasteilen belegt ist oder in die Glasteile eingebettet sind um das Kabel nagetierfest zu machen.Such a cable is from DE-0S 35 02 042 known. The known cable has an extrudable Plastic layer, which is covered with glass parts or embedded in the glass parts around the cable to make rodent-proof.

Der Erfindung liegt die Aufgabe zugrunde ein Kabel mit einem anderen metallfreien Nagetierschutz anzugeben.The invention has for its object a cable another metal-free rodent protection.

Die Lösung dieser Aufgabe erfolgt mit den im Hauptanspruch genannten Mitteln. Vorteilhafte Weiterbildungen sind in den Unteransprüchen enthalten.This problem is solved with the im Main claim means. Beneficial Further training is contained in the subclaims.

Die Erfindung hat den Vorteil, daß sie problemlos bei allen Arten von Kabeln angewendet werden kann. Eine Vorrichtung zum Aufbringen des Nagetierschutzes kann sogar nachträglich in bestehende Kabelfertigungsanlagen leicht eingebaut werden.The invention has the advantage that it is easy to use all types of cables can be used. A Device for applying the rodent protection can even retrospectively in existing cable production plants can be easily installed.

Die Erfindung wird nachstehend anhand eines in der einzigen Figur dargestellten Ausführungsbeispiels erläutert. Weitere Ausführungen sind in der Beschreibung enthalten.The invention is described below using a single figure shown embodiment explained. Further versions are in the description contain.

Das in der Figur im Querschnitt dargestellte optische Kabel weist eine Seele auf, die sechs um ein Zentralelement 1 angeordnete Bündeladern 2 enthält, die von einer Bewicklung 3 zusammengehalten sind. Die Bewicklung 3 ist von einem kunststoffbeschichteten Aluminiumband 4 umgeben, auf das ein Kunststoffinnenmantel 5 aufgebracht ist. Um den Kunststoffinnenmantel 5 ist längslaufend mit Überlappung ein Band 6 aus Schleifleinen oder Schmirgelpapier gelegt, wobei die Schleifseite nach außen orientiert ist. Um den Bandformprozeß zu erleichtern wird über das Band 6 eine Kunststoffolie 7 aufgebracht. Die Bänder 6 und 7 werden durch eine Kunststoffhaltewendel 8 zusammengehalten. Darüber befindet sich ein Kunststoffaußenmantel 9.The optical cable shown in cross-section in the figure has a core which contains six loose tubes 2 arranged around a central element 1 , which are held together by a winding 3 . The winding 3 is surrounded by a plastic-coated aluminum strip 4 , on which a plastic inner jacket 5 is applied. A band 6 of abrasive cloth or emery paper is placed lengthwise with overlap around the plastic inner jacket 5 , the abrasive side being oriented outwards. In order to facilitate the band forming process, a plastic film 7 is applied over the band 6 . The tapes 6 and 7 are held together by a plastic holding helix 8 . A plastic outer jacket 9 is located above it.

Das Band 6 kann bei anderen Kabelausführungen auch wendelförmig überlappt gewickelt sein. Die Überlappungszone ist mit einem Schmelzkleber, beispielsweise TPX 20-030 der Firma Henkel, verklebt. Geeignete Bänder besitzen Schleifkörner aus Quarzglas, Siliziumkarbid oder Aluminiumoxid mit einer Korngröße zwischen P60 und P120, beispielsweise die Typen ALF 632-P80 der Firma Carborundum oder 3M453-P60 der Firma 3M-Company.The band 6 can also be wound helically overlapping in other cable designs. The overlap zone is glued with a hot melt adhesive, for example TPX 20-030 from Henkel. Suitable belts have abrasive grains made of quartz glass, silicon carbide or aluminum oxide with a grain size between P60 and P120, for example the types ALF 632-P80 from the company Carborundum or 3M453-P60 from the company 3M-Company.

Die Kunststoffolie 7 besteht vorzugsweise aus Polyäthylen und dient als Schutzfolie um den sonst möglicherweise durch das Band 6 hervorgerufenen Verschleiß der Bandformwerkzeuge und Führungsnippel zu verhindern. The plastic film 7 is preferably made of polyethylene and serves as a protective film in order to prevent the band mold tools and guide nipples that may otherwise be caused by the band 6 .

Der Innen- und der Außenmantel bestehen aus den bei Kabeln üblichen Kunststoffen. Sie können zugfeste Elemente aus Glas oder Aramid enthalten. Besonders vorteilhaft ist es auf das Band 6 oder die Kunststoffolie 7 Glasfaserstränge, beispielsweise Hercuflex HF 2000 oder 4000 der Firma PPG Industries aufzubringen.The inner and outer sheaths are made from the usual plastics used in cables. They can contain tensile elements made of glass or aramid. It is particularly advantageous to apply glass fiber strands, for example Hercuflex HF 2000 or 4000 from PPG Industries, to the band 6 or the plastic film 7 .
