摘要： An apparatus for producing an assembly of filamentary elements that are wound together in a helix includes a twisting device, a preforming device, and an assembling device. The twisting device is structured to twist at least first and second filamentary elements individually, such that each filamentary element is twisted separately from another filamentary element, to produce at least first and second twisted filamentary elements. The preforming device, which is arranged downstream of the twisting device, is structured to preform each of the twisted filamentary elements individually into separate preformed helixes, to produce at least first and second preformed helixes. The assembling device, which is arranged downstream of the preforming device, is structured to assemble the preformed helixes into an assembly.

摘要： A facility for manufacturing at least first and second assemblies of M1 filamentary elements and M2 filamentary elements, in which each of the first and second assemblies includes a plurality of filamentary elements wound together in a helix, includes an assembling apparatus and a splitting apparatus. The assembling apparatus of the facility assembles M filamentary elements together into a layer of M filamentary elements around a temporary core, to form a temporary assembly. The splitting apparatus of the facility splits the temporary assembly into at least the first and second assemblies of M1 filamentary elements and M2 filamentary elements.

摘要： An adapter for a rolling assembly having an axis of rotation (YY′), the rolling assembly comprising a tyre having two beads, and a rim having two rim bead seats, for each bead, provides the connection between the bead and the rim, the said adapter comprising an axially inner end connected to the rim, an axially outer end comprising an outer reinforcing element and intended to come into contact, via a substantially radial axially inner face, or bearing face, with a bead, a body connecting the axially outer end to the axially inner end so as to form a single piece, comprising at least one main reinforcement providing the connection between the outer reinforcing element and the inner reinforcing element, and comprising a substantially axial adapter seat intended to come into contact with a bead. The outer reinforcing element is completely axially on the outside of the bearing face, and the outer reinforcing element is a substantially annular structure, referred to as a bead wire, of polygonal section, comprising an individual metal wire of diameter D1, the said wire being coated in an elastomer composition and wound contiguously around a support at least three times in an axial direction and at least twice in a radial direction.

摘要： The method allows the manufacture of at least first and second assemblies (26, 28) of M1 filamentary elements and M2 filamentary elements, at least one of the first and second assemblies (26, 28) comprising several filamentary elements (14) wound together in a helix.The method comprises a step of assembling M filamentary elements (14) together into a layer of the M filamentary elements (14) around a temporary core (16) to form a temporary assembly (22), and a step of splitting the temporary assembly (22) into at least the first and second assemblies (26, 28) of M1 filamentary elements and M2 filamentary elements.

摘要： A cord (50) comprises a single layer (52) made up of N helically wound metal filamentary elements (54) having an outer diameter D, the metal filamentary elements (54) defining an internal enclosure (58) of the cord of diameter Dv. Each metal filamentary element (54) has a diameter Df and a helix radius of curvature Rf. With this cord (50), D, Dv, Df and Rf being expressed in millimeters: 0.10≤Jr≤0.25, 9≤Rf/Df≤30, and 1.60≤Dv/Df≤3.20, where Jr=N/(π*(D−Df))×(Dh×Sin(π/N)−(Df/Cos(αx π/180))) and α is the helix angle, expressed in degrees, of each metal filamentary element (54).

摘要： The method makes it possible to manufacture an assembly (A) comprising a layer (C) of metal filamentary elements (14) wound in a helix. The method comprises a step (100) of supplying a temporary assembly (22) comprising a layer (13) of M′>1 metal filamentary elements (14) and a temporary centre (16), and a step (110) of separating the temporary assembly (22) between a first split assembly (25), a second split assembly (27) and the temporary centre (16). The method comprises a step (140) of reassembling the first split assembly (25) with the second split assembly (27) so as to form the layer (C) of the assembly (A).

摘要： The subject of the invention is a cord (50) comprising a single layer (52) of helically wound metal filamentary elements (54). The metal filamentary elements define an internal enclosure (58) of the cord of diameter Dv. Each metal filamentary element (54) has a diameter Df and a helix radius of curvature Rf.
With Dv, Df and Rf being expressed in millimetres, the cord satisfies the following relationships: 9≤Rf/Df≤30, and 1.30≤Dv/Df≤2.10.
