  • elastomeric material such as polyurethane of the type
  • a steel wire or reinforcement placed eccentrically to the inside of this cladding sheath and being closer to the face lower than the upper face of said sheath, the thickness of the sheath coating above the steel wire being more important than the thickness of the parts of the covering sheath framing laterally and from below the steel wire.
  • the invention also relates to screening fabrics of the type comprising a plurality of sheathed, corrugated and juxtaposed steel wires between two planes parallel tangent to the web of said wires, the sheathed steel wires having a cross section that fits into a rectangle, on the one hand two lateral sides are substantially perpendicular to the tangent planes of the ply of yarn and of which, on the other hand, the two lower and upper sides are substantially parallel to the tangent planes of the layer of wires, these wires sheathed each comprising an elastomeric sheath and a wire steel or reinforcement placed eccentrically inside this sheath.
  • Known steel wires sheathed with an elastomer layer have a circular cross section and the layer of elastomer surrounding the wire and adhering to the latter has a circular annular shape of thickness constant.
  • This type of sheathed wire is known for example from the patent FR 2,394,393 which, as an elastomeric material, offers, inter alia, polyurethane and recommends that the thickness of the elastomer layer be a value between 0.3 to 5 times the diameter of the steel wire.
  • a first object of the present invention is to provide a wire steel sheathed in elastomeric material, in particular in polyurethane which allows to make screening fabrics having both a very good permeability and high resistance or resistance to abrasion.
  • This first object is achieved with a sheathed steel wire according to claim 1.
  • the amount of the elastomeric material and accordingly the thickness of the coating layer above the steel wire and constituting in a way the thickness of wear which conditions the holding or abrasion resistance of the sheathed wire, is more important than the thickness of the coating parts framing laterally and from below the steel wire whose transverse width or diameter conditions with the thickness of elastomeric coating side parts, the permeability of the fabric screening carried out with said sheathed wires.
  • the height of the cross section of the steel wire placed on edge conditions the resistance or mechanical strength in the direction of the load of materials, that is to say in the direction of the action of the weight of the materials, while the width of the cross section of the steel wire conditions the width of the section of steel wire coated or sheathed with material elastomer and therefore, consequently, the permeability of the canvas screening using such sheathed wires.
  • the provision on edge of the wire steel favors the corrugation of the sheathed wires.

  • Each screening tablecloth is composed of a series of elastomer bars in each of which is embedded a metallic core, placed in parallel and whose the spacing, corresponding to the sorting difference, is variable thanks to the possibility to tension more or less the fixing beams also in elastomer which are joined to the bars by vulcanization.
  • due to the elasticity of these fixing beams it is not possible to ensure correct tensioning of the bars and the non-extensible metal core is likely to dissociate, at least at its ends, from the material elastomer constituting the bars and the fixing beams.
  • the metal core is arranged so that the longer side of its section is parallel to the tangent plane of the water table, the useful screening surface is relatively small compared to the total area of the water table.

  • the patent FR 1 217 457 presents a flexible bottom of a sieve in which horizontally corrugated steel wires are alternated with wires of steel corrugated vertically. These vertical undulations create a reserve lengthening likely to eventually relax these vertically wavy wires ensuring the mechanical strength of the screen bottom.
