Definitions

  • the invention relates to a reinforcement rope made of metal wires for elastomeric products.
  • Reinforcement ropes are usually embedded in layers in the elastomeric products, for example in the manufacture of pneumatic vehicle tires, drive belts or conveyor belts.
  • metal wires are arranged in a single strand with a single wire diameter of usually 0.12 to 0.5 mm, usually in one or two layers.
  • a single wire diameter usually 0.12 to 0.5 mm, usually in one or two layers.
  • This higher load capacity is required, for example, when using the reinforcement ropes in truck pneumatic tires and in the air ceilings of earthmoving machines.
  • Single stranded metal wires, several of which are rewound to a two or multiple rope, are called strands.
  • reinforcement ropes with multiple stranding i.e. reinforcement ropes which consist of at least two strands stranded together, each consisting of two or more wires, are preferably used under higher loads.
  • the object of the invention is therefore to provide a reinforcement rope for elastomeric products, which consist of at least two strands stranded together, each consisting of two or more wires, which, after being embedded in the elastomeric material, has approximately the same or the same behavior against corrosion as the ropes in simple stranding.
  • a reinforcement rope of the type mentioned above which is characterized in that at least one outer strand consists of two or more core wires wound helically by at least one strand wrap wire. It is particularly advantageous if each outer or even each strand consists of two or more core wires wound helically by at least one strand wrap wire.
  • the metal wires should bond well with the elastomeric material. However, they can also be coated with a second metal, plastic or another material, with a good tendency to bind between the metal wire and the coating material on the one hand and the coating material and elastomeric material on the other hand.
  • Wires made of steel, usually made of carbon steel, are also particularly suitable, but also made of other types of steel, for example made of alloyed or high-alloyed steels with a low Fe content. Steel wires coated with brass are preferred.
  • Outside strands are to be understood as the strands that are visibly on the outside of the finished reinforcement rope.
  • one or more strands can be installed.
  • the strands of at least one Seilumschlingun g sdraht total and / or at least one Seilumschlingungslitze are wrapped helically.
  • the invention consists g sseil from three to seven strands of up to four Seilumschlingungsdrähten and / or up to four Seilumschlingungslitzen.
  • strands are understood to be strands in the reinforcement rope, which are generally present in a larger number than the rope-wrapping strands.
  • strands and rope-wrapping strands there can also be the same number of strands and rope-wrapping strands, one group of strands and the other group of rope-wrapping strands being named for distinction.
  • the strands and / or the rope wrapping strands contain two to eight core wires; however, more core wires are also possible.
  • the strands and / or the rope looping strands generally contain up to four strand looping wires, a larger number also being possible here.
  • the core wires are understood to be those wires in the strand or rope wrap strand which are generally in the majority.
  • Strand wrap wires are understood to be those wires in the strand or rope wrap strand which are generally in fewer numbers.
  • the strands or the rope wrapping strands can contain, for example, 3 + 1, 5 + 2, 6 + 3, 7 + 2, or generally n 1 + n 2 wires, the first number or n 1 being the number of core wires and the second number or n 2 indicates the number of strand wrap wires.
  • the core wires and strand-wrapping wires are of helical shape with the same pitch, the same pitch angle and the same direction of rotation, and the core wires of a strand are arranged bundled almost in phase.
  • the preferred lay length is 10 to 20 mm.
  • the core wires of the strands and / or the rope wrapping strands are arranged next to one another and against one another such that each of the core wires is in linear contact with at least one other core wire, the contact line running parallel to the direction of the core wires.
  • These strands are known as reinforcement ropes in simple stranding from DE-OS 26 19 086.
  • the reinforcement Ropes have been found to be particularly favorable for use as reinforcement ropes in elastomeric products, since the loop wire also has a load-bearing function and, moreover, the elastomeric material also penetrates particularly well into the core area of the rope when the rope is embedded, and thus also corrosion of the wires severe damage is largely prevented.
  • the strands and the rope wrapping wires and / or rope wrapping strands are of helical shape with the same pitch, the same pitch angle and the same direction of rotation, and the strands are arranged bundled almost in phase.
  • the strand wrap wires are arranged out of phase with the core wires, preferably shifted by half a pitch length.
  • the preferred lay length for the second stranding is 10 to 30 mm.
  • the method known from DE-OS 26 19 086 is used to produce the rope for the second stranding, instead of the core wires Strands and instead of the roping wires, rope wrapping wires and / or rope wrapping strands are used.
  • the reinforcing ropes according to the invention are preferably used in the manufacture of pneumatic vehicle tires, in particular pneumatic tires for trucks or earth moving machines
