- a sheath of elastomeric material such as polyurethane of the type
- a sheath of elastomeric coating having a cross section which is inscribed in a rectangle whose height is at least equal to its width
- a steel wire or reinforcement placed eccentrically inside this covering sheath and being closer to the lower face than to the upper face of said sheath, the thickness of the sheath of
- the invention also relates to screening fabrics of the type comprising a plurality of sheathed steel wires, corrugated and juxtaposed between two parallel planes tangent to the web of said wires, the sheathed steel wires having a cross section which fits into a rectangle of which on the one hand the two lateral sides are substantially perpendicular to the tangent planes of the ply of wires and of which, on the other hand, the two lower and upper sides are substantially parallel to the tangent planes of the ply of wires, these wires sheathed each comprising an elastomeric coating sheath and a steel wire or reinforcement placed eccentrically inside this sheath.
- Known steel wires sheathed with an elastomer layer have a circular cross section and the elastomer layer surrounding the wire and adhering to the latter has a circular annular shape of constant thickness.
- This type of sheathed yarn is known for example from patent FR 2394393 which, as an elastomeric material, proposes inter alia, polyurethane and recommends that the thickness of the elastomeric layer has a value of between 0.3 to 5 times the diameter of the steel wire.
- the coating for example of polyurethane
- said coating is "punctured" or otherwise damaged by the materials passing over and / or through the screen cloth.
- the steel wires of the screening cloth are quickly exposed and said cloth shows premature wear.
- the polyurethane coating is given too great a thickness in order to eliminate or delay the wear of the wires, then the permeability of the screen fabric is considerably reduced.
- the permeability of the screening fabric is understood to mean the ratio between the sum of all the passage sections of a fabric and the sum of the cross sections occupied by the sheathed wires for a fabric surface and a given number of wires.
- a first aim of the present invention consists in proposing a steel wire sheathed in elastomeric material, in particular in polyurethane which makes it possible to produce screening fabrics having both very good permeability and great resistance or resistance to abrasion.
- This first object is achieved with a sheathed steel wire of the type defined initially because the steel wire or reinforcement has a cross section whose height taken in the direction parallel to the direction of the passage of the load materials through the fabric screen is greater than the width of the section of the steel wire and that the height or thickness of the layer of the covering sheath situated above the reinforcing steel wire is at least equal to half of the total height of said sheath or that the thickness of the elastomeric sheath located above the steel wire is at least equal to or greater than twice the thickness of said elastomeric sheath located below the wire d 'steel.
- the quantity of the elastomeric material and consequently the thickness of the coating layer lying above the steel wire and constituting in a way the thickness of wear which conditions the resistance 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 the lateral parts of elastomeric coating, the permeability of the canvas screening carried out with said sheathed wires.
- the height of the cross section of the steel wire placed on edge conditions the strength 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.
- the width of the cross section of the steel wire conditions the width of the section of the steel wire coated or sheathed with elastomeric material and therefore, consequently, the permeability of the canvas screening using such sheathed wires.
- the provision on edge of the steel wire promotes the undulation of the sheathed wires.
- a screen fabric consisting of a plurality of steel wires juxtaposed so as to form a plurality of passage meshes and held together by plastic transverse bands which are arranged at distances regular and which connect the steel wires juxtaposed to each other, leaving a certain passage interval between the parts of wires not covered by said strips.
- the steel wires used in this kind of fabric can be corrugated so that the corrugated axis of said circular section wires lies in a plane perpendicular to the axes of the meshes or passage openings delimited by the corrugated wires. In this case, a curved part of a corrugated wire touches a part of a neighboring corrugated wire.
- Document DE 27 46 408 presents a screening box with a screening body composed of a plurality of screening plies. Each screening sheet is composed of a series of elastomer bars in each of which is embedded a metal core, placed in parallel and whose spacing, corresponding to the sorting gap, is variable thanks to the possibility of stretching more or minus the fixing beams also made of elastomer which are joined to the bars by vulcanization.
- a screening plate in the form of a grid, in one piece and structured so that, for the same thickness, its service life is increased compared to pre-existing screening plates.
- This plate consists of two layers of elastic material superimposed and perforated to form openings delimiting meshes.
- the layer facing the entry of the bulk materials has increased abrasion resistance and consequent hardness, in particular thanks to the presence of fillers.
- a reinforcement can be embedded in the lower support layer opposite the loading surface.
- This one-piece plate structure generates a low useful screening surface and a significant risk of dowelling.
- the patent FR 1 217 457 presents a flexible bottom of a screen in which horizontally corrugated steel wires are alternated with vertically corrugated steel wires. These vertical corrugations create an elongation reserve which may eventually relax these vertically corrugated wires ensuring the mechanical strength of the screen bottom.
- Another object of the invention consists in eliminating or at least attenuating the drawbacks of existing screening fabrics and in providing a fabric which has an optimal ratio between abrasion resistance and permeability, as well as a satisfactory tension. throughout its lifetime.

- branches of corrugated wires In order to increase the useful screening area, it is advantageous for the branches of corrugated wires to have an orientation of 45 ° with respect to the routing of the materials on the surface of the screening fabric.
- the ends of the sheathed steel wires are embedded in longitudinal connecting beams produced by molding in an elastomeric material, said beams are connected by a transverse beam in which a plate is embedded reinforcement having through holes and said longitudinal beams are engaged laterally in the housing suitable for an adaptation profile which, under the action of a series of keys, is fixed on a support rail.
- the ends of the sheathed steel wires are retained by longitudinal connecting beams made of a sheet folded in a U forming a hook at its folded ends which cooperate with the end of a tension plinth, the other end of which rests on the side wall of the frame of the screen fabric and the middle part of which is held by a tensioning device bearing on said side wall.

- the sheathed steel wire 1 has a cross section in the shape of a right trapezoid which also fits into a rectangle 4 and the largest base of which is located on the side of the upper face of said wire 1. It is advantageous that the small base of the trapezium is not less than two thirds of the large base of the trapezium in order to avoid too great a variation in the free cross section of the passage openings between two neighboring wires as the wear of the sheath 2 of the sheathed wires 1.
- the sheathed steel wires 1 having the structure described above can be used in the straight and / or corrugated state.
- the sheathed steel wires 1 are corrugated perpendicularly to their vertical extension, that is to say at their height, and in this case have, for a given screening fabric, a plurality of successive sections whose pitch and the amplitude of ripple are identical and constant.

- branches of corrugated wires 1B it is advantageous for the branches of corrugated wires 1B to have an orientation of 45 ° with respect to the routing of the materials on the surface of the screen cloth 5. It appears from FIGS. 4A and 5 that the ends of the sheathed steel wires
- 1, 1A, 1B are embedded in longitudinal beams 7 produced by molding in an elastomeric material such as polyurethane.
- the front ends of these longitudinal so-called connecting beams 7 are connected by a transverse beam 8 in which is embedded a reinforcing plate 9 made of steel whose through holes 10 allow better anchoring of the reinforcing plate 9 in the elastomeric material such as polyurethane constituting said transverse beam 8.
- the longitudinal beams 7 have a rectangular cross section and are engaged laterally in the appropriate housing 11 of an adaptation profile 12 which, under the action of a series of keys 13, is fixed on a support rail 14. It it should be noted that the adaptation profile 12 receives by the key 13 once mounted on the rail 14 sufficient pressure to wedge the longitudinal beam 7 in its housing 11 between the nose 12A and the base 12B of the adaptation profile.
- FIG. 6 to 8 and 10 is shown another embodiment of a screen fabric according to the invention.
- the longitudinal beams 7 are provided with tension hooks 15 which receive in their hollow one end of a tension plinth 16, formed of a sheet metal profile, the other end of which rests on the wall lateral 17 of the frame of the screening fabric and the middle part of which is held by a tensioning device 18 bearing on said lateral wall 17.
- the tension hooks 15 are formed in a single piece resulting from the folding of a sheet forming a longitudinal beam 7, as can be seen in FIG. 10.
- the tension hook 15 is produced as follows: the two end parts of the straight sheathed wires 1A are twisted by rotation through 90 ° around their longitudinal axis so that these end parts have a reduced height equal to the width of the rectangle in which the cross section of the sheath 2 is inscribed.
- the corrugated sheathed wires IB have a reduced length compared to that of the straight sheathed wires 1A, the position of the free end of the corrugated sheathed wires IB corresponding substantially at the position of the twisted portion of the straight sheathed wires 1A, when the wires 1A, IB are placed side by side.

- each straight wire 1A, a free end of each corrugated wire IB and the stabilization strip 19 are sandwiched inside the sheet, forming the longitudinal beam 7, folded in a U, the two walls forming the branches of the U being crushed on the wires 1A, IB. It then suffices to fold the end portion of the beam, which retains the twisted end portions of the straight wires 1A, more than 90 ° around a longitudinal axis to form a continuous longitudinal hook cooperating with the tension plinth 16 to stretch the screen cloth.
- the fabric has only straight wires 1A, in order to avoid their overlapping when they are placed side by side after the twisting operation, it is necessary that the height of the rectangle in which the sheath 2 is inscribed that is less than the sum between the width of this rectangle and the sorting distance or difference separating two adjacent straight wires.
- stabilization 19 are preferably formed in the form of a woven steel grid and placed at regular distances from one another on the upper face of the ply of sheathed steel wires 1, 1A, IB.
- the polyurethane strips 20 or an equivalent material are superimposed on the stabilization strips 19 and are heated with hot air so as to melt part of the polyurethane mass and to pass it through the mesh of the stabilization strips. 19 and to be bonded by fusion or welding with the upper part of the sheath 2 of the sheathed steel wires 1.
- wires 1 are provided below and in face of the stabilization strips 19 of the screen supports 21, the structure of which is known.
- the advantages of sheathed steel wires and screen cloths using such wires are numerous. Among these advantages, one will cite that of being able to have for screening a wear and routing surface of materials that is perfectly flat. No wire is therefore in relief compared to another and therefore does not offer any privileged wear area. This results in a better lifespan compared to traditional woven fabrics.
- each straight and / or wavy thread can vibrate independently of the neighboring threads. This results in better efficiency and a limitation of the problems of dowelling due to materials which remain trapped in a mesh of the screen fabric.
- steel wires according to the invention can be used for the production of stretched screening fabrics (FIGS. 6 to 8 and 10) or of screening canvas panels (FIGS. 4A, 4B, 5).
- the embodiments previously described can undergo a number of modifications without departing from the scope of the invention determined by the appended claims.
