Description

Die Erfindung bezieht sich auf Gegenstände, die aus Kautschuk oder Kautschukaustauschstoffen und in Form von Drahtlitzen oder Drahtseilen vermendeten Aletalldrahteinlagen zusammengesetzt sind, und befaßt sich im besonderen mit der Ausbildung der Drahtlitzen oder Drahtseile. The invention relates to articles made of rubber or Rubber substitutes and used in the form of wire strands or wire ropes Aletallwires are composed, and deals in particular with the Formation of wire strands or wire ropes.

Es ist bekannt, Drahtlitzen oder Drahtseile für allgemeine Verwendung mit Weichstoffseelen, z. B. aus Hanf, auszurüsten. Diese Weichstoffseele soll dem bekannten Drahtseil eine größere Biegefähigkeit verleihen. It is known to use wire strands or ropes for general purposes with soft souls, e.g. B. from hemp to equip. This soft soul is supposed to give known wire rope a greater flexibility.

Als Einlagen für Kautschukgegenstände, die auch großen Zugbeanspruchungen unterworfen werden, hat man bisher Drahtseile und Drahtlitzen nur vereinzelt und meist ohne Erfolg verwendet, da die bekaniiten Drahtlitzen bzw. -seile eine zu geringe elastische Dehnung aufweisen. As inserts for rubber items that are also subject to high tensile loads are subjected, wire ropes and wire strands have so far only been isolated and mostly used without success because the known wire strands or ropes are too small exhibit elastic elongation.

Die erfindungsgemäßen Verstärkungseinlagen für Gegenstände aus Kautschuk bestehen aus Drahtlitzen oder -seilen mit unvulkanisierter oder vorvulkanisierter Kautschukseele, bei denen die Einzeldrähte oder -litzen in Abständen voneinander liegen. The reinforcement inserts according to the invention for articles made of rubber consist of wire strands or ropes with unvulcanized or pre-vulcanized Rubber core in which the individual wires or strands are spaced from one another lie.

I)ie Kautschukseelen verleihen den Seilen bzw.I) The rubber cores give the ropes or

Litzen eine hohe elastische Dehnung. Bei einer Zugbeanspruchung des Seiles wird zwar auch z. B. eine Hanfeinlage auf einen geringeren Querschnitt zusammengedrückt. Sie hat aber nach dem Aufhören der Zugbeanspruchungen nicht das Bestreben, in ihre alte Form zurückzukehren und übt auch keine dementsprechenden Kräfte auf die umschließenden Metalldrähte aus. Anders dagegen verhalten sich die Kautschukseelen. Beim Einleiten von Zugbeanspruchungen in das Seil werden sie auch zusammengedrückt. Hierbei entstehen in der Kautschukseele aber elastische Rückstellkräfte, die als Druckkräfte nach außen wirken und bei Aufhören der Zugbeanspruchung im Seil die einzelnen. Drähte wieder kräftig nach außen drücken. Durch die erfindungsgemäße Ausbildung wirkt daher das Seil in Längsrichtung stark federnd und erhält einen sehr hohen elastischen Dehnungsanteil, der es erst als Einlage fiir viele Kautschukgegenstände geeignet macht.Strands have a high elastic elongation. If the Rope is also z. B. compressed a hemp insert to a smaller cross-section. But after the tensile stress has ceased, she does not strive to get into her to return to the old form and also does not exert any corresponding forces on the enclosing one Metal wires. The rubber souls behave differently. When initiating they are also compressed by tensile stresses in the rope. Here arise in the rubber core, however, elastic restoring forces act as compressive forces act outside and when the tensile stress in the rope ceases, the individual. Wires press firmly outwards again. The inventive training therefore acts the rope is strongly resilient in the longitudinal direction and is given a very high elasticity Elongation component, which makes it suitable only as an insert for many rubber objects power.

Eine wertvolle Eigenheit der Erfindung besteht darin, daß die Einzeldrähte nicht dicht nebeneinanderliegen, so daß während der Vulkanisation der Kautschukhüllstoff mit den Kautschukseelen eine Verbindung eingehen kann. Im fertigen Bauteil ist dann jeder Metalldraht vollständig von Kautschuk masse umgeben, wodurch eine feste gegenseitige Verankerung der Metall- und Kautschukteile erhalten wird. A valuable feature of the invention is that the individual wires do not lie close to one another, so that the rubber wrapping material during vulcanization can enter into a connection with the rubber souls. In the finished component is then each metal wire is completely surrounded by rubber mass, creating a solid mutual Anchoring the metal and rubber parts is obtained.

Um den die Metalldrähte allseitig umschließenden Kautschukwerkstoff vollkommen homogen zu gestalten, befindet sich der Werkstoff der Seele vor der Einbettung der Litzen oder Seile in den Kautschukgegenstand im unvulkanisierten oder nur vorvulkanisierten Zustande. Beim Vulkanisieren des bereits fertig zusammengesetzten ganzen Bauteiles gehen dabei die Seelen mit dem umschließenden Kautschukhüllstofi eine so innige Verbindung ein, daß eine Grenzbildung später nicht mehr feststellbar ist. Around the rubber material surrounding the metal wires on all sides To make it completely homogeneous, the material of the soul is before embedding of the strands or ropes in the rubber article in the unvulcanized or only pre-vulcanized Conditions. When vulcanizing the entire component that has already been assembled the souls go so intimately with the surrounding rubber envelope Connection that a boundary formation can no longer be determined later.

Es ist bekannt, Drahtseile, die als selbständige Gegenstände, z. ß. für Hebezwecke, Verwendung finden sollen, mit Gummimasse zu durchsetzen und zu umgeben, um die abträglichen Verschmutzungswirkungen, die durch die sonst auf den Seilen befindlichen Schmierstoffe verursacht werden, zu beheben. Eine ähnliche Seilausführung wurde als Schleppseil für Fischerei zwecke vorgeschlagen. It is known to use wire ropes as independent objects, e.g. ß. for lifting purposes, should be used to enforce with rubber mass and to surrounded by the deleterious pollution effects otherwise caused by the Lubricants located in ropes. A similar type of rope has been proposed as a tow for fishing purposes.

Ebenso ist es bekannt, bei elektrischen Kabeln zur Weiterfeitung von Strömen unterhalb der Metalldrahtumflechtung eine Gummischicht vorzusehen. It is also known for electrical cables to be passed on of currents to provide a rubber layer below the metal wire braiding.

Derartige Kabel sind aber durch das in der Mitte befindliche starke Metalleiterbündel so unelastisch gegenüber Zugbeanspruchungen daß das elastische Dehnungsverhalten durch den Gummi nicht beeinflußt wird.Such cables are strong due to the strong one in the middle Metal conductor bundle so inelastic to tensile stresses that the elastic Stretch behavior is not influenced by the rubber.

In der Zeichnung sind zwei Ausführungsbeispiele erfindungsgemäßer Drahteinlagen dargestellt. In the drawing, two exemplary embodiments of the invention are shown Wire inlays shown.

Abb. I zeigt den Querschnitt durch eine Litze, bei der in einfacher Weise die Einzeldrähte I um einen Kernstrang 2 aus Kautschuk herumgelegt sind. Der Kernstrang 2 ist so stark bemessen, daß die Drähte 1 nicht gegenseitig zur Anlage gelangen, sondern zwischen ihnen Zwischenräume freibleiben, durch welche der Hüllstoff mit dem Kernstrang in Verbindung treten kann. Fig. I shows the cross-section through a stranded wire in which in simple Way, the individual wires I are wrapped around a core strand 2 made of rubber. Of the Core strand 2 is dimensioned so strong that the wires 1 do not rest against each other get, but gaps remain free between them, through which the wrapping material can connect with the core strand.

In Abb. 2 ist ein Querschnitt durch ein Seil wiedergegeben, bestehend aus sechs Litzen, wobei die Einzeldrähte I auf den Kautschukkernen 3 aufliegen. Diese Litzen sind wiederum um einen Kautschukkern 4 größeren Querschnittes herumgelegt. In Fig. 2 a cross section through a rope is shown, consisting of six strands, the individual wires I resting on the rubber cores 3. These strands are in turn wrapped around a rubber core 4 with a larger cross section.
