Description

Verfahren zum Verscbließen der Schnittflächen an den Enden von kunstoffumhüllten Drähten Um Drähte und Drahtgeflechte gegen Korrosion zu schützen, verwendet man in neuerer Zeit Drähte, die mit einer Kunststoffumhüllung versehen sind. An den Schnittflächen solcher Drähte bzw. aus solchen Drähten hergestellter Drahtgeflechte hat jedoch die Luft freien Zutritt zum Kerndraht, so daß die Gefahr besteht, daß von der Schnittkante aus unter dem Kunststoffmantel ein Verrosten des Kerndrahtes einsetzt. Method for sealing the cut surfaces at the ends of plastic-coated Wires To protect wires and wire meshes against corrosion, one uses more recently wires that are provided with a plastic sheath. To the Cut surfaces of such wires or of wire meshes made from such wires however, the air has free access to the core wire, so that there is a risk that rusting of the core wire from the cut edge under the plastic jacket begins.

Dies kann soweit führen, daß der Kunststoff zunächst im Bereich der Drahtenden, schließlich aber immer weiter abblättert, so daß der Korrosionsschutz völlig verlorengeht.This can lead to the fact that the plastic is initially in the area of the Wire ends, but eventually continue to peel off, so that the corrosion protection is completely lost.

Es ist bekannt, Gegenstände mit einer Schutzschicht aus Kunststoffen in der Weise zu versehen, daß die auf etwa 80 bis 1200 C erwärmten Gegenstände z. B. durch Tauchen mit einer Kunststoffdispersion überzogen und anschließend getrocknet werden. Ein solches Verfahren ist zum Verschließen der Schnittflächen an den Enden von kunststoffumhüllten Drähten praktisch nicht anwendbar, da das Eintauchen der Enden der Drähte eines durch die Flechtmaschine hindurchlaufenden oder von der Flechtmaschine kommenden Drahtgeflechtes mit großen Schwierigkeiten verbunden sein würde. Ferner ist die lange Erhärtnngszeit eines flüssigen Kunststoffes mit der maschinellen Herstellung von Maschendraht unvereinbar. Da beim Spannen von kunststoffumhüllten Drähten, z. B. den Spanndrähten eines Maschendrahtes, der gespannte Draht erst am Verwendungsort abgeschnitten wird, ist das bekannte Verfahren auch hier nicht anwendbar. It is known objects with a protective layer made of plastics to provide in such a way that the heated to about 80 to 1200 C objects z. B. coated by dipping with a plastic dispersion and then dried will. One such method is to seal the cut surfaces at the ends of plastic-coated wires practically inapplicable, since the immersion of the Ends of the wires of one passing through the braiding machine or from the braiding machine coming wire mesh would be associated with great difficulties. Further is the long hardening time of a liquid plastic with mechanical production incompatible by wire mesh. Since when tensioning plastic-coated wires such. B. the tension wires of a wire mesh, the tensioned wire only at the place of use is cut off, the known method cannot be used here either.

Um diesen Mangel zu beseitigen, wird erfindungsgemäß ein einfaches und wirksames Verfahren vorgeschlagen, das ein Abblättern der Kunststoffumhüllung an den Drahtenden von kunststoffumhüllten Drähten und aus solchen bestehenden Drahtgeflechten verhindert und einen vollen Korrosionsschutz gewährleistet. Das Verfahren gemäß der Erfindung besteht in erster Linie darin, daß die Kunststoffumhüllung, die erforderlichenfalls im Bereich des Drahtendes mittels Wärme, vorzugsweise mittels eines Warmluftstromes, vom Kerndraht gelöst worden ist, ein Stück über das Kerndrahtende vorgezogen und die vorgezogene Kunststoffhülle alsdann durch Verschweißen unter Druck verschlossen wird. Auf diese Weise wird eine vollkommen dichte Umhüllung des Kerndrahtes erzielt und ein Verrosten desselben verhindert. In order to overcome this deficiency, the present invention is a simple one and proposed effective method of peeling off the plastic wrap at the wire ends of plastic-coated wires and wire meshes made of such prevents and guarantees full corrosion protection. The procedure according to the invention consists primarily in the fact that the plastic casing, if necessary in the area of the wire end by means of heat, preferably by means of a stream of hot air, has been detached from the core wire, pulled forward a little over the end of the core wire and the plastic cover, which has been drawn up, is then closed by welding under pressure will. In this way a completely tight covering of the core wire is achieved and prevents it from rusting.

Eine Vereinfachung des Verfahrens kann gemäß einem weiteren Schritt der Erfindung dadurch erzielt werden, daß man die zum Vorziehen des Kunststoffmantels über das Drahtende erforderliche Zange vorwärmt und mit dieser vorgewärmten Zange das Lösen des Kunststoffmantels vom Kerndraht durchführt. The method can be simplified in accordance with a further step the invention can be achieved by the fact that for pulling the plastic jacket preheated the necessary pliers over the wire end and with these preheated pliers detaching the plastic sheath from the core wire.

Auch kann das Verfahren gemäß der Erfindung in Verbindung mit den bekannten Verfahren zur automatischen Herstellung von Drahtgeflecht kombiniert werden, wobei die Arbeitsgänge des Erwärmens, Vorziehens und Verschweißens der Kunststoffhülle der umhüllten Drähte mit einem Sonderwerkzeug der Geflechtmaschine durchgeführt werden können.The method according to the invention can also be used in conjunction with the known processes for the automatic production of wire mesh are combined, wherein the operations of heating, pulling and welding of the plastic casing of the sheathed wires is carried out with a special tool of the braiding machine can be.

Als Ausführungsbeispiel der Erfindung sind in der Zeichnung schematisch Verfahrensschritte des Verfahrens gemäß der Erfindung dargestellt und nachstehend beschrieben. Es zeigt Fig. 1 die Vorwärmung des Drahtendes, Fig. 2 das Vorziehen der vom Kerndrahtende gelösten Kunststoffhülle über das Drahtende und Fig. 3 das Verschließen der über das Kerndrahtende vorgezogenen Kunststoffhülle. As an embodiment of the invention are shown schematically in the drawing Process steps of the method according to the invention are shown and below described. It shows Fig. 1 the preheating of the wire end, Fig. 2 the pulling forward the plastic sheath loosened from the core wire end over the wire end and Fig. 3 the Closing the plastic sheath pulled over the end of the core wire.

Der mit einer Kunststoffhülle 1 versehene Kerndraht 2 wird im Bereich des Drahtendes durch einen aus einer Düse 3 austretenden Warmluftstrom 4 erwärmt. Dadurch wird der Kunststoffmantel 1 vom Kerndraht 2 gelöst und geweitet, so daß er mittels eines zangenartigen Werkzeuges 5 um einige Millimeter über das Kerndrahtende vorgezogen werden kann. Der über das Kerndrahtende vorgezogene Teil der Kunststoffumhüllung wird sodann mit einer zweiten Zange6 zusammengedrückt und verschweißt, so daß das Drahtende vollkommen verschlossen ist. The core wire 2 provided with a plastic sheath 1 is in the area the end of the wire is heated by a stream of hot air 4 emerging from a nozzle 3. As a result, the plastic jacket 1 is released from the core wire 2 and widened so that he by means of a pliers-like tool 5 by a few millimeters over the end of the core wire can be preferred. The part of the plastic sheath pulled over the end of the core wire is then pressed together with a second pair of pliers6 and welded so that the Wire end is completely closed.
