Abstract:
A tire having a radial carcass reinforcement, comprised of at least one layer of metal reinforcing elements, said tire comprising a crown reinforcement, which is itself covered radially with a tread, said tread being joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are non-hooped cords having, in the permeability test, a flow rate of less than 20 cm3/min and at least one layer of the carcass reinforcement being provided on at least one side with textile threads oriented mainly along a direction parallel to that of the metal reinforcing elements of said at least one carcass reinforcement layer, said textile threads being corrugated about this main direction.
Abstract:
An object of the present invention is to make it possible to provide a cord, in particular, a cord for reinforcing a rubber article in which rubber permeation properties are improved by coating filaments as constituents of the cord with rubber in a reliable and stable manner. The cord of the present invention is produced by, when the metal filament is guided to an extruder and extruded together with rubber from a mouthpiece of the extruder so that the metal filament is coated with the rubber, juxtaposing plural metal filaments in the mouthpiece and extruding the metal filaments together with rubber.
Abstract:
In order that spaces, including a space in the central portion, inside a steel cord used as a reinforcement by being embedded in a tire or the like are filled with an uncured rubber, the uncured rubber is coated on plural steel core filaments which are then stranded to form a single layer steel cord, the core then being stranded with uncoated outer layer filaments. Consequently, it is possible to exhibit satisfactory corrosion resistance and satisfactory fatigue resistance as a steel cord, shorten a curing time in tire component assembling or the like to attain energy saving and prolong the life of a steel cord itself and the life of a tire or the like using the same as a reinforcement. Further, production can be performed at low cost.
Abstract:
J strands form a core. K outer strands are wound around it in a helix with pitch PK, each having a cord with an L wire inner layer of diameter d1, and an M wire outer layer of diameter d2, wound around the inner layer in a helix with pitch p2; with (in mm): 0.10
Abstract:
Metal cord with three concentric layers including a first layer of diameter dc made up of M wire(s) of diameter d1, around which are wound as a helix at a pitch p2, as a second layer, N wires of diameter d2, around which are wound as a helix at pitch p3, as a third layer, P wires of diameter d3. Some gaps or capillaries in the cord situated between the core and the second layer and between the core wires themselves when M is greater than 1 and between the N wires of the second layer and the P wires of the third layer, contain a filling rubber based on an unsaturated thermoplastic elastomer

Abstract:
A metal cord (C-1) having two layers (Ci, Ce) of 3+N construction, rubberized in situ, comprising an inner layer (Ci) formed from three core wires (10) of diameter d, wound together in a helix with a pitch p1 and an outer layer (Ce) of N wires (11) N varying from 6 to 12, of diameter d2, which are wound together in a helix with a pitch p2 around the inner layer (Ci), said cord being characterized in that it has the following characteristics (d1, d2, p1 and p2 being in mm): 0.08
Abstract:
The present invention relates to a three-layered metal cable of construction L+M+N usable as a reinforcing element for a tire carcass reinforcement, comprising an inner layer C1 having L wires of diameter d1 with L being from 1 to 4, surrounded by an intermediate layer C2 of M wires of diameter d2 wound together in a helix at a pitch p2 with M being from 3 to 12, said layer C2 being surrounded by an outer layer C3 of N wires of diameter d3 wound together in a helix at a pitch p3 with N being from 8 to 20, said cable being characterised in that a sheath formed of a cross-linkable or cross-linked rubber composition based on at least one diene elastomer covers at least said layer C2. The invention furthermore relates to the articles or semi-finished products made of plastics material and/or rubber which are reinforced by such a multi-layer cable, in particular to tires used in industrial vehicles, more particularly heavy-vehicle tires and their carcass reinforcement plies.
