Description

Mit Längsrippen versehene Kunststoffumhüllung für Kabel sowie Verfahren und Vorrichtung zu ihrer Herstellung Es ist bereits bekannt, den gewellten Metallmantel eines Kabels mit einer Schutzhülle aus thermoplastischen oder vulkanisierten Stoffen zu umhüllen, weiche der Wellenform des Kabelmantels angepaßt ist und dessen Wellentäler durch Längsrippen überbrückt, deren Rückenlinien von der Mittellinie der Kabelseele praktisch überall den gleichen Abstand haben. Die Kunststoffhülle liegt dabei mit einer gleichbleibenden Wanddicke zwischen den Rippen auf dem Metallmantel fest auf. Plastic casing with longitudinal ribs for cables and processes and device for their manufacture It is already known the corrugated metal jacket a cable with a protective sheath made of thermoplastic or vulcanized materials to encase, soft is adapted to the wave shape of the cable jacket and its wave troughs bridged by longitudinal ribs, their back lines from the center line of the cable core have the same distance practically everywhere. The plastic cover is included a constant wall thickness between the ribs on the metal jacket.

Es ist ferner bekannt, Luftkabel mit ihrem Tragseil in der Weise auszuführen, daß das Kabel und das Tragseil in einer gemeinsamen Hülle eingebettet sind, die zwischen beiden einen Steg bildet. It is also known to use aerial cables with their supporting cable in the manner execute that the cable and the suspension rope embedded in a common sheath are, which forms a web between the two.

Ferner sind Kabel mit einem glatten Metallmantel und einer glatten Kunststoffumhüllung bekannt, in der eine offene Drahtarmierung eingebettet ist. Furthermore, cables with a smooth metal jacket and a smooth one Known plastic casing in which an open wire armouring is embedded.

Die Erfindung betrifft eine mit Längsrippen versehene Kunststoffumhüllung für Kabel, in der eine offene Armierung angeordnet ist. Die Erfindung besteht darin, daß jedes Element der offenen Armierung als Gerüst für eine Rippe der Kunststoffumhüllung dient. Unter Kabel sind dabei metallmantelumhüllte oder metallmantelfreie Kabel zu verstehen, die eine glatte oder gewellte Oberfläche aufweisen. Jedes Element der Armierung kann aus einem nichtmetallischen oder metallischen, massiven oder hohlen Faden, Draht, Band oder Seil bestehen. Es kann parallel zur Längsachse des Kabels angeordnet sein oder wendelförmig um das Kabel verlaufen. The invention relates to a plastic casing provided with longitudinal ribs for cables in which an open armouring is arranged. The invention consists in that each element of the open reinforcement as a framework for a rib of the plastic casing serves. Under cables are cables that are covered with a metal jacket or cables that are free from metal jackets to understand that have a smooth or wavy surface. Every element The reinforcement can be made of a non-metallic or metallic, solid or consist of hollow thread, wire, tape or rope. It can be parallel to the longitudinal axis of the Be arranged cables or run helically around the cable.

Die achsparallele Anordnung der Armierungselemente ist bei solchen Kabeln vorteilhaft, die in ihrer Längsrichtung beansprucht werden, wie z. B. freihängende Schachtkabel. The axially parallel arrangement of the reinforcing elements is in such Advantageous cables that are stressed in their longitudinal direction, such. B. free-hanging Manhole cables.

Die Kunststoffumhüllung wird zweckmäßig mit den bekannten Schneckenpressen gefertigt, mit denen thermoplastische oder vulkanisierbare Stoffe als Schlauch über einen zylindrischen Hohldorn ausgespritzt und mit Vakuum auf das durch den Hohldorn hindurchlaufende Kabel angesaugt werden. Zweckmäßig werden die Elemente der Armierung mit gegenseitigen Abständen zwischen Kabel und Schlauch durch den Kopf der Schneckenpresse hindurchgeführt. Der Schlauch wird dabei vorzugsweise mit einer gleichbleibenden Wanddicke in der Umfangs- und in der Längsrichtung auf dem zylindrischen Hohldorn aufgespritzt und dann vom Schlauchinnern her unter Vakuum gesetzt. Dabei legt er sich fest um jedes Armierungselement und auch fest auf das Kabel auf. The plastic casing is expediently made with the known screw presses manufactured using thermoplastic or vulcanizable substances as a hose over injected a cylindrical hollow mandrel and vacuum on it through the hollow mandrel running cables are sucked in. The elements of the reinforcement are expedient with mutual distances between cable and hose through the head of the screw press passed through. The hose is preferably with a constant Wall thickness in the circumferential and in the longitudinal direction on the cylindrical hollow mandrel sprayed on and then put under vacuum from the inside of the hose. In doing so, he lays firmly around each reinforcement element and also firmly on the cable.

Infolgedessen bildet der Schlauch entsprechend der Anzahl der Armierungselemente Rippen. Jede dieser Rippen enthält als Gerüst ein Element der Armierung.As a result, the hose forms according to the number of reinforcement elements Ribs. Each of these ribs contains an element of the reinforcement as a framework.

Die Elemente der Armierung werden, wenn sie parallel zur Kabelachse in der Kunststoffhülle eingebettet sind, zweckmäßigerweise bei der Herstellung der Hülle mit den vorgesehenen gegenseitigen Abständen achsparallel in die Schneckenpresse eingeführt. Das ist mit einfachen Mitteln durchführbar. Wenn die Elemente der Armierung in der Kunststoffumhüllung wendelförmig angeordnet sein sollen, so werden sie entweder wendelförmig um das Kabel herumgelegt, bevor es durch die Schneckenpresse hindurchgeschickt wird, oder es wird ein Spinnkorb, dessen Hohlwelle in den Hohl dorn der Schneckenpresse reicht, vor dem Einlauf der Schnekkenpresse angeordnet. Das Kabel wird dann in die Hohlwelle des Spinnkorbes eingeführt.The elements of the armouring are when they are parallel to the cable axis are embedded in the plastic shell, expediently in the manufacture of the Sheath with the intended mutual distances axially parallel into the screw press introduced. This can be done with simple means. When the elements of reinforcement are to be arranged helically in the plastic casing, they will either helically wrapped around the cable before it is sent through the screw press is, or it is a spinning basket whose hollow shaft in the hollow mandrel of the screw press is enough, arranged in front of the inlet of the screw press. The cable then plugs into the Hollow shaft of the spinning basket introduced.

Die Zeichnung dient zur Erläuterung. Es zeigt Fig. 1 einen Querschnitt und Fig. 2 eine Ansicht der erfindungsgemäßen Armierung eines Kabels mit gewelltem Metallmantel, Fig. 3 einen Längsschnitt des Spritzkopfes der Schneckenpresse mit dem davor angeordneten Spinnkorb und dem teilweise im Schnitt gezeigten armierten Kabel. The drawing serves as an explanation. 1 shows a cross section and FIG. 2 shows a view of the reinforcement according to the invention of a cable with a corrugated Metal jacket, Fig. 3 with a longitudinal section of the extrusion head of the screw press the spinning basket arranged in front of it and the armored one partially shown in section Cable.

In der Zeichnung bedeutet 1 die Kabelseele, 2 den Metallmantel, 3 den Spritzkopf, 4 den im Spritzkopf angeordneten Hohldorn, auf dem der Schlauch aus Kunststoff entsteht, 5 den Kunststoffschlauch unmittelbar beim Verlassen des Hohldornes, 5' den auf das Kabel angesaugten Schlauch, 6 die Elemente der offenen Armierung, 7 die im Hohldorn angeordnete Hohlwelle des Spinnkorbes, 8 den Spinnkorb und 9 den Anschluß für die Vakuumanlage. In the drawing, 1 means the cable core, 2 the metal jacket, 3 the spray head, 4 the hollow mandrel arranged in the spray head on which the hose made of plastic, 5 the plastic tube immediately upon leaving the Hollow mandrel, 5 'the hose sucked onto the cable, 6 the elements of the open Reinforcement, 7 the hollow shaft of the spinning basket arranged in the hollow mandrel, 8 the spinning basket and 9 the connection for the vacuum system.
