Abstract

The system to twist strands of glass fibres into a cord, such as for industrial conveyor belt applications, uses a thermoplastic or elastomeric cladding for the glass fibres before they are twisted. The system gives protection against abrasion between the strans when they are twisted, to give a flexible and strong cord which can be wound can be wound round a drum. The cladding material can be a PVC or a natural or synthetic rubber. The glass fibre strands are either attached to each other by the thermoplastic or elastomeric material, or are individually clad with the matl. The result is a strong glass fibre material with about 100% stretch without the individual strands tearing or breaking.

Description

Aus Glasfasersträngen bestehendes Seil Die Erfindung betrifft ein aus Glasfasersträngen bestehendes Seil, dessen einzelne Glasfasern von einer Kunststoffschicht umhüllt sind. The invention relates to a rope made of fiberglass strands Rope consisting of glass fiber strands, the individual glass fibers of which are covered by a plastic layer are wrapped.

Aus Glasfasern bestehende Seile sind bereits bekannt, beispielsweise aus der US-PS 3 079 664. Zur Verbesserung der Gleiteigenschaften und der Abriebeigenschaften sind bei diesem Seil die einzelnen Glasfasern teilweise mit einem Überzug aus Graphit und teilweise mit einem Überzug aus Metall versehen. Ein derartiges Seil hat nur eine geringe Flexibilität.Ropes made of glass fibers are already known, for example from US-PS 3,079,664. To improve the sliding properties and the abrasion properties In this rope, the individual glass fibers are partially covered with a graphite coating and partially provided with a metal coating. Such a rope only has poor flexibility.

Ein weiteres Seil der eingangs genannten Art ist aus der DU-AS 1 510 095 bekannt. Bei diesem Seil sind die einzelnen Glasfasern mittels eines wärmehärtenden Kunstharzes fest miteinander verbunden. Die einzelnen Litzen sind mit einem Schmiermittelüberzug versehen, damit sie gegeneinander bewegbar sind. Ein derartiges Seil kann dynamisch nur wenig beansprucht werden. Ferner ist ein derartiges Seil nicht dazu geeignet, leber Trommeln mit geringem Durchmesser gefuhrt zu werden.Another rope of the type mentioned at the beginning is from DU-AS 1 510 095 known. In this rope, the individual glass fibers are thermosetting Resin firmly bonded together. The individual strands are with a Lubricant coating provided so that they can be moved relative to one another. Such a rope can be dynamic are only slightly stressed. Furthermore, such a rope is not suitable for liver drums with small diameter to be guided.

Der Erfindung liegt die Aufgabe zugrunde, ein aus Glasfasersträngen bestehendes Seil zu schaffen, das dynamisch hoch beansprucht werden kann und das so flexibel ist, daß es auch über Trommeln mit geringem Durchmesser geführt werden kann, ohne daß sich die einzelnen Glasfasern oder Litzen gegeneinander verschieben. Derartige Anforderungen werden beispielsweise an Seile gestellt, ie dazu bestimmt sind, in Fördergurte eingebettet zu werden.The invention is based on the object of a made of glass fiber strands To create an existing rope that can withstand high dynamic loads and that is so flexible that it can also be guided over small-diameter drums can without the individual glass fibers or strands shifting against each other. Such requirements are placed on ropes, for example, ie they are intended to do so are to be embedded in conveyor belts.

Die Lösung der-gestellten Aufgabe besteht in erster Linie darin, daß die die einzelnen Glasfasern umhüllende Kunststoffschicht aus einem thermoplastischen oder elastomeren Werkstoff gebildet ist, wobei zweckmäßigerweise die Glasfaserstränge zu Litzen verdrillt sind.The solution to the problem is primarily that the plastic layer enveloping the individual glass fibers made of a thermoplastic or elastomeric material is formed, expediently the glass fiber strands are twisted into strands.

Thermoplastische und elastomere Werkstoffe weisen ein gummielastisches Verhalten auf. Die Dehnungswerte können erheblich über 100 ffi betragen. Dadurch kann das erfindungsgemäße Seil dynamisch hoch beansprucht werden, ohne daß die einelnen Litzen reißen oder brechen.Thermoplastic and elastomeric materials are rubber-elastic Behavior on. The elongation values can be considerably more than 100 ffi. Through this the rope according to the invention can be dynamically highly stressed without the individual The strands tear or break.

Gemäß einem weiteren Schritt der Erfindung ist die Verdrillung der Glasfaserstränge und die Verseilung gegenläufig.According to a further step of the invention, the twisting is the Glass fiber strands and the stranding run in opposite directions.

Die die einzelnen Glasfasern umhüllende Kunststoffschicht kann entweder aus Polyvinylchlorid (PVC) oder aus Natur- oder Synthesekautschuk bestehen.The plastic layer enveloping the individual glass fibers can either consist of polyvinyl chloride (PVC) or natural or synthetic rubber.

In weiterer Ausgestaltung der Erfindung sind die Glasfaserstränge durch einen thermoplastischen oder elastomeren Werkstoff miteinander verklebt. Dadurch wird ein Verschieben der Glasfaserstränge gegeneinander verhindert.In a further embodiment of the invention, the glass fiber strands are glued together by a thermoplastic or elastomeric material. Through this the glass fiber strands are prevented from shifting against each other.

Bei einem Seil, das für die Einbettung in einen Gummi- oder Kunststoffgegenatand bestimmt ist, ist es vorteilhaft, daß es eine Umhüllung aus einem thermoplastischen oder elastomeren Werkstoff aufweist.In the case of a rope that is to be embedded in a rubber or plastic object is determined, it is advantageous that there is an envelope made of a thermoplastic or having elastomeric material.
