Description

Verfahren zur Bedeckung von Leitungsdrähten Die Isolierung elektrischer Leitungen durch eine Hülle aus verschiedenen hochwertigen Kunststoffen, insbesondere Polyvinyläthern und -estern, insonderheit Polyvinylchlorid, ließ sich bisher nur durch Umspritzen ermöglichen: Die Stoffe erwiesen sich für die Verarbeitung in der Bedeckungs- oder Schermaschine als ungeeignet, so daß man bisher notgedrungen auf das durch seine hohe Arbeitsgeschwindigkeit, geringen Verluste, mögliche Herstellung einer Vielzahl von isolierten Leitungen nebeneinander, in vielen Fällen zu bevorzugende Bedeckungsverfahren verzichten mußte.Method of covering conductor wires The insulation of electrical Lines through a cover made of various high-quality plastics, in particular Polyvinyl ethers and esters, especially polyvinyl chloride, could only be used up to now enable by overmolding: The substances have been proven for processing in the Covering or shearing machine as unsuitable, so that one has so far been forced to this thanks to its high working speed, low losses, and possible manufacturing a large number of insulated lines next to each other, preferable in many cases Had to forego covering procedures.

Die Erfindung zeigt nun einen Weg, diese Schwierigkeit zu vermeiden, indem es gelungen ist, die Isolierung mit Polyvinyläthern und -estern, insbesondere mit Polyvinylchlorid, in der Weise herbeizuführen, daß die einlaufenden Kunststoffbänder unmittelbar vor dem Eintritt in die Bedeckungs-oder Scherwalzen auf .eine Temperatur von ioo° C und darüber, zweckmäßig in den Grenzen von iao bis i5o'° C, erhitzt werden, während die Temperatur der Bedeckungswalzen so bemessen wird, daß ein Kleben der Isolierbänder an den Walzen vermieden wird.The invention now shows a way to avoid this difficulty, by successfully isolating with polyvinyl ethers and esters, in particular with polyvinyl chloride, in such a way that the incoming plastic strips to a temperature immediately before entry into the covering or shear rollers heated from 100 ° C and above, expediently within the limits of iao to 150 ° C, while the temperature of the covering rollers is measured so that sticking of the Isolation tapes on the rollers is avoided.

Die Durchführung des Verfahrens erfolgt zweckmäßig in der Weise, daß die Bänder vor dem Einlaufen in die erste Bedeckungswalze durch einen vergleichsweise langen und bis zum Griff der Walze sich verlängernden Heizkasten geleitet werden, der durch elektrische Beheizung in genau regelbarer Weise erhitzt werden kann. Bei der Herstellung von mehreren Bedeckungslagen wird man die Heizkästen zwischen dem ersten und den folgenden Bedeckungswalzenpaaren kürzer halten können, nach Maßgabe des bei den Bedeckungsmaschinen normalerweise schon festgelegten Walzenabstandes, weil ja hier der zu isolierende Leitungsdraht und die in den ersten Walzen angebrachte Isolierschicht schon eine gewisse Wärmemenge zuführen.The method is expediently carried out in such a way that the belts before entering the first cover roll by a comparator long heating boxes extending to the handle of the roller, which can be heated in a precisely controllable manner by means of electrical heating. at The heating boxes become one of the production of several layers of covering between the first and the following pairs of covering rollers can keep shorter, according to the proviso the roller spacing that is normally already set for the covering machines, because this is where the conductor wire to be insulated and the one attached to the first rollers Apply a certain amount of heat to the insulating layer.

Die Einregelung der Temperatur der Walzen zwecks Verhinderung des Anklebens wird bei den verschiedenen in Frage kommenden Kunststoffen in verschiedener Weise erfolgen. Beispielsweise wird man bei Bedeckung mit Polyvinylchlorid mit kalten Walzen arbeiten; bei hoher Raumtemperatur kann das unter Umständen zur Anbringung von Kühlvorrichtungen für die Walzen nötigen. Bei anderen Stoffen mit hoher Verschweißungstemperatur, z. B. bei Polyvinylkarbazol, wird es erforderlich werden können, die Walzen auf eine Temperatur zu beheizen, die noch über der Temperatur liegt, mit der die Isolierbänder den Heizkasten verlassen. Auf diese Weise werden die Hälften :der Isolierhülle einwandfrei miteinander verbunden bzw. , verschweißt, während ein Ankleben der Schicht an den auf geeignete Temperatur gebrachten Walzen nicht eintritt.The regulation of the temperature of the rollers in order to prevent the Gluing is done in different ways with the various plastics in question Way to be done. For example, if it is covered with polyvinyl chloride, it will be cold Rolling work; If the room temperature is high, this may lead to the attachment of cooling devices for the rollers. For other materials with a high welding temperature, z. B. in the case of polyvinyl carbazole, it may be necessary to open the rollers to heat a temperature that is still higher than the temperature at which the insulating tapes leave the heating box. In this way, the halves: the insulating sleeve will be flawless connected to one another or, welded, while sticking the layer to the rolls brought to a suitable temperature does not occur.
