Abstract

Fishing line having low distension and high tensile strength comprises braided micro-fibres pref. carbon fibres which are passed through a bath of thermoplastics melt or through an extruder to bond the fibres together and also to provide an external sleeve.

Description

Es ist bekannt Schnüre aus Kunststoffen herzustel- It is known to produce cords from plastics

lein, Monofile Schnüre bestehen aus verstreckten Polyamidfäden.Linen, monofilament lines consist of stretched polyamide threads.

Ferner sind auch Schnüre aus miteinander verflochtenen Polyamidfäden bekannt0 Diese Schnüre haben aber eine begrenzte Zerreißfestigkeit und eine erhebliche Dehnung. Besonders die letztere Eigenschaft ist bei Anwendungen nachteilig, bei denen eine verlustarme und unverzögerte Übertragung einer Kraft durch die Schnur anzustreben ist. Bei Verwendung als Angelschnur beispielsweise besteht auf Grund der verzögerten Übertragung der Kraft der Nachteil, dass beim Anhieb der Fisch sich noch vom Haken befreien kann, bevor die von der Angelrute zugeleitete Kraft am Haken voll zur Wirkung kommt.There are also cords made of interwoven polyamide threads known0 These cords have a limited tensile strength and a considerable Strain. The latter property in particular is disadvantageous in applications which a low-loss and instantaneous transmission of a force through the cord is to strive for. When used as a fishing line, for example, there is a reason the delayed transmission of the force has the disadvantage that when the fish is first hit, the problem is can still be released from the hook before the force applied by the fishing rod to the hook comes into full effect.

Der Erfindung liegt die Aufgabe zugrunde, eine Schnur hoher Zerreißfestigkeit und geringer Dehnung zu schaffen, die eine verlustarme und unverzögerte Kraftübertragung er möglichst. The invention is based on the object of a cord with high tensile strength and low elongation to create a low-loss and instantaneous power transmission he as possible.

Diese Aufgabe wird durch die im Patentanspruch 1 herausgestellten Verfahrenschritte gelöst. This object is highlighted by those in claim 1 Process steps solved.

Weitere vorteilhafte Verfahrensmaßnahmen ergeben sich aus den Unteransprüchen, Die verwendeten Fäden haben eine hohe Zerreißfestig keit bei geringer Dehnung in Längsrichtung, können aber allein keine funktionsfähige Schnur bilden, Ferner ist ihre Festigkeit in Querrichtung nur gering, Durch die erfindungsgemässe Vereinigung mit dem thermoplastischem Kunststoff, beispielsweise einem Polyamid, erhält die Schnur einmal die erforderliche Formhaltigkeit, zum anderen eine Stabilisierung der Ausrichtung der Fäden und schliesslich eine die Beschädigung der empfindlichen Fäden verhindernde Schutzhülle, ohne dass die vorteilhaften Eigenschaften der Fäden beeinträchtigt werden. Further advantageous procedural measures result from the subclaims, The threads used have a high Zerreißfestig speed with low elongation in Longitudinal direction, but cannot form a functional cord on their own their strength in the transverse direction is only slight, due to the combination according to the invention with the thermoplastic, for example a polyamide, the cord receives the required shape retention on the one hand, and stabilization on the other the alignment of the threads and ultimately damage to the delicate ones Threads-preventing protective cover without losing the beneficial properties of the threads be affected.

Die Verbindung der Fasern mit dem thermoplastischer Kunststoff erfolgt vorteilhaft mittels eines Extruders, Jedoch können die Fäden auch durch ein Bad des thermoplastischen Kunststoffs gezogen werden und anschliessend das Kalibrieren zur Schnur in einer Ziehdüse erfolgen0 Infolge der hohen Zerreißfestigkeit ergibt sich eine gleichgrosse Bruchlast wie bei bekannten Polyamidschnüren bereits bei einem beachtlich kleinerem Durchmesser, so dass zum Beispiel auf der Spule einer Angelrolle in vorteilhafter Weise eine grössere Länge bereitgestellt werden kann. The connection of the fibers with the thermoplastic takes place advantageously by means of an extruder, but the threads can also pass through a bath of the thermoplastic plastic are drawn and then the calibration to the cord in a drawing nozzle 0 results due to the high tensile strength a breaking load of the same size as with known polyamide cords a considerably smaller diameter, so that, for example, a Fishing reel can advantageously be provided a greater length.
