Description
La présente invention a pour objet un produit maillé ou un média filtrant à mailles fines ou très fines et/ou à grande transparence, dont la rigidité et/ou la résistance mécanique sont considérablement améliorées par une armature extérieure,
Pour ce faire le produit maillé ou le média filtrant à renforcer est inséré entre les deux réseaux croisés de fils ou profilés parallèles entre eux, les dits réseaux étant rendus solidaires par assemblage à leurs points de croisement au travers du produit maillé ou du média filtrant à renforcer.The subject of the present invention is a mesh product or a filter medium with fine or very fine meshes and / or with high transparency, the rigidity and / or mechanical strength of which are considerably improved by an external reinforcement,
To do this, the mesh product or the filter medium to be reinforced is inserted between the two crossed networks of wires or profiles parallel to each other, the said networks being made integral by assembly at their crossing points through the mesh product or the filter medium to to reinforce.
Il est connu des produits maillés et des médias filtrants qui présentent des ouvertures de mailles fines ou très fines et/ ou une grande transparence, mais dont la rigidité et/ou la résistance mécanique est (sont) généralement faibles. Leur extrême souplesse est un obstacle à leur mise en forme durable et est généralement insuffisante pour présenter une résistance mécanique propre satisfaisante à l'emploi; c'est le cas des produits suivants - Tissus, tricots, tresses : textiles, synthétiques ou métalli
ques - Treillis métalliques fins réalisés par soudage en croix de fils
de diamètres généralement inférieurs à 1,5 mm - Tôles perforées fines ou micrométal déployé.Mesh products and filter media are known which have openings of fine or very fine meshes and / or great transparency, but whose rigidity and / or mechanical strength is (are) generally low. Their extreme flexibility is an obstacle to their lasting shaping and is generally insufficient to have a proper mechanical strength satisfactory for use; this is the case for the following products - Fabrics, knits, braids: textiles, synthetics or metalli
ques - Fine wire mesh produced by cross-wire welding
diameters generally less than 1.5 mm - Perforated thin or micrometal sheets deployed.
- et tous autres produits analogues utilisés dans les technique
de séparation, triage, tamisage, séchage, aération, filtration
et micro-filtration, séparation de phases, protection mécanique
blindage, etc.- and all other similar products used in the techniques
separation, sorting, sieving, drying, aeration, filtration
and micro-filtration, phase separation, mechanical protection
shielding, etc.
Pour apporter à ces produits connus une résistance mécanique suffisante pour résister aux efforts auxquels ils sont soumis en service normal, ils sont généralement combinés avec des éléments de support ou de renfort réalisés en matériaux plus résistants et plus massifs; placés sur une face ou sur l'autre ou encore sur les deux faces des produits maillés ou des médias filtrants, soit généralement - Tôle perforée épaisse à trous de formes diverses, plane ou ner
verée ou ondulée - Grillage ondulé - Armature ou treillis en
fils soudés en croix - Métal déployé, laminé ou non - Armature
plastique - Réseau de fils parallèles ronds ou de forme, etc.To provide these known products with sufficient mechanical strength to withstand the forces to which they are subjected in normal service, they are generally combined with support or reinforcement elements made of more resistant and more massive materials; placed on one side or the other or on both sides of mesh products or filter media, either generally - Thick perforated sheet with holes of various shapes, flat or ner
worm or corrugated - Corrugated mesh - Reinforcement or trellis
cross welded wires - Expanded metal, laminated or not - Reinforcement
plastic - Network of parallel round or shaped wires, etc.
Toutes ces solutions se caractérisent par le fait que le produit maillé ou le média filtrant est renforcé par l'apport d'éléments de support rajoutés, même si quelquefois pour des raisons de commodité à l'usage le produit maillé ou le média filtrant est rendu solidaire de son élément de support par tous moyens connus tels que : soudage, collage, agrafage, etc. All these solutions are characterized by the fact that the mesh product or the filtering medium is reinforced by the addition of added support elements, even if sometimes for reasons of convenience in use the mesh product or the filtering medium is rendered secured to its support element by any known means such as: welding, bonding, stapling, etc.
Un autre moyen connu pour renforcer le produit maillé ou le média filtrant consiste à surmouler une armature généralement en plastique ou en métal à bas point de fusion (Zamac par exemple) sur un produit maillé ou un média filtrant pour créer une structure de renfort faisant corps avec celui-ci. Another known way to reinforce the mesh product or the filtering medium consists in overmolding a generally plastic or metal frame with low melting point (Zamac for example) on a mesh product or a filtering medium to create a reinforcement structure forming a body with this one.
Le produit de la présente invention s'écarte totalement de ces réalisations connues. The product of the present invention deviates completely from these known embodiments.
Le renforcement mécanique du produit maillé ou média filtrant est obtenu par son insertion dans la structure de renfort au moment même de la mise en oeuvre de la dite structure. The mechanical reinforcement of the mesh product or filtering medium is obtained by its insertion into the reinforcement structure at the very moment of the implementation of said structure.
Cette structure de renfort est réalisée selon le procédé connu d'assemblage de deux nappes de fils de section ronde ou non ou de profilés, parallèles entre eux, disposés en croix. Les dites nappes faisant généralement un angle de 900 entre elles. This reinforcing structure is produced according to the known method of assembling two layers of son of round or non-round section or of profiles, parallel to one another, arranged in a cross. Said plies generally making an angle of 900 between them.
Ces structures de renfort, ou armatures, en fils ou profilés disposés en croix sont généralement obtenues par soudage, agrafage ou collage des fils ou profilés à leurs points d'intersection. These reinforcing structures, or reinforcements, in wires or profiles arranged in a cross are generally obtained by welding, stapling or gluing the wires or profiles at their points of intersection.
Le mérite de l'invention est d'avoir profité de la conception particulière de cette armature, réalisée par assemblage de deux nappes de fils ou profilés parallèles entre eux, disposés en croix, pour insérer entre les deux nappes, au moment de l'assemblage des dits fils ou profilés, le produit maillé ou le média filtrant dont on veut renforcer la rigidité et/ou la résistance mécanique. The merit of the invention is to have taken advantage of the particular design of this frame, produced by assembling two plies of wires or profiles parallel to one another, arranged in a cross, to insert between the two plies, at the time of assembly. so-called wires or profiles, the meshed product or the filtering medium whose rigidity and / or mechanical strength is to be reinforced.
Les diverses caractéristiques et divers avantages de l'invention ressortiront de la description qui va suivre d'une des formes possibles de réalisation, étant bien précisé qu'il s'agit d'un exemple non limitatif et que toutes autres formes, proportions et dispositions pourraient être adaptées sans sortir du cadre de l'invention. The various characteristics and various advantages of the invention will emerge from the description which follows of one of the possible embodiments, it being clearly specified that this is a non-limiting example and that all other forms, proportions and arrangements could be adapted without departing from the scope of the invention.
Les 5 dessins annexés représentent différentes formes possibles de réalisation. Les figure 1 et figure 2 montrent un tissu métallique à mailles fines, renforcé par insertion entre les deux nappes de fils parallèles d'une armature soudée en fils métalliques de section ronde. The 5 accompanying drawings show different possible embodiments. FIGS. 1 and FIG. 2 show a metallic fabric with fine mesh, reinforced by insertion between the two plies of parallel wires of a frame welded in metallic wires of round section.
Un tissu métallique 1 présentant une ouverture de mailles de 0,5 mm réalisé en fils d'acier inoxydable de ~ 0,32 mm est inséré, au moment de la fabrication du treillis d'armature sur machine automatique, par soudage entre une des nappes de fils parallèles entre eux, en fils de ~ 3 mm acier inoxydable, disposés à un entr'axe de 50 mm 2 et une autre nappe de fils parallèles entre eux ~ 3 mm en acier inoxydable disposés à un entr'axe de 50 mm 3
Ces deux nappes de renfort 2 et 3, sont assemblées entre elles aux points de croisement par soudage par résistance à travers le tissu métallique qui est ainsi pris en sandwich et emprisonné dans les deux nappes de fils de renfort ce qui permet de créer un nouveau produit monolithique conservant la transparence élevée et les ouvertures de maille calibrées résultant des caractéristiques propres du tissu métallique, auxquelles on a ajouté la rigidité et la résistance mécanique élevées conférées par les caractéristiques propres de l'armature en fils ou profilés soudés en croix.A metallic fabric 1 having a mesh opening of 0.5 mm made of stainless steel wire of ~ 0.32 mm is inserted, at the time of manufacture of the reinforcing mesh on an automatic machine, by welding between one of the plies of wires parallel to one another, of wires of ~ 3 mm stainless steel, arranged at a center distance of 50 mm 2 and another ply of wires parallel to each other ~ 3 mm of stainless steel arranged at a center distance of 50 mm 3
These two reinforcing plies 2 and 3, are assembled together at the crossing points by resistance welding through the metallic fabric which is thus sandwiched and trapped in the two plies of reinforcing threads which makes it possible to create a new product. monolithic retaining the high transparency and the calibrated mesh openings resulting from the inherent characteristics of the metallic fabric, to which the high rigidity and mechanical resistance conferred by the inherent characteristics of the reinforcement in cross-welded wires or profiles have been added.
La conception et la mise en oeuvre de l'armature réalisée par deux nappes de fils ou profilés parallèles entre eux disposés de part et d'autre du produit maillé ou du média filtrant, permettent de réaliser des produits aux caractéristiques variées et adaptés aux conditions d'emploi. The design and implementation of the armature produced by two plies of wires or profiles parallel to one another arranged on either side of the mesh product or of the filtering medium, make it possible to produce products with varied characteristics and adapted to the conditions of 'employment.
Dans la réalisation décrite ci-avant les deux nappes de la structure de renfort sont réalisées avec des fils ou profilés de même section, disposés à entr'axes égaux. In the embodiment described above, the two plies of the reinforcing structure are produced with wires or profiles of the same section, arranged at equal centers.
Le produit maillé ou média filtrant renforcé présente donc une rigidité et une résistance mécanique identiques dans les deux sens de passage, ce qui peut être avantageux, par exemple pour le décolmatage des médias filtrants par la méthode connue de l'inversion du flux dite à contre-courant. The reinforced mesh product or filter media therefore has identical rigidity and mechanical strength in both directions of passage, which can be advantageous, for example for unclogging the filter media by the known method of reverse flow called counter -current.
Dans une variante de l'invention, une des nappes de fils ou profilés de renfort peut être réalisée avec des fils ou profilés de plus forte section que les fils ou profilés de l'autre nappe l'espacement entre fils ou profilés des deux nappes restant identiques. Ceci apporte au produit de l'invention une résistance mécanique accrue dans un des sens de passage, tout en allégeant la structure de renfort. In a variant of the invention, one of the plies of wires or reinforcing profiles can be produced with wires or profiles of greater cross section than the wires or profiles of the other ply the spacing between wires or profiles of the two remaining plies identical. This provides the product of the invention with increased mechanical strength in one of the directions of passage, while reducing the reinforcement structure.
Le même résultat pourrait être obtenu, figure 4, en conservant pour les deux nappes des fils ou profilés de même section 2 et 3, mais en les disposant avec un entr'axe plus rapproché sur une des faces du produit maillé ou du média filtrant å renforcer. The same result could be obtained, FIG. 4, by conserving for the two plies wires or profiles of the same section 2 and 3, but by arranging them with a closer center distance on one of the faces of the mesh product or of the filtering medium å to reinforce.
Dans l'exemple de la figure 4 les fils 2 d'une des nappes sont disposés avec entr'axe plus rapproché que les fils 3 de l'autre nappe. La section des'fils étant identique pour les deux nappes disposées en croix. In the example of FIG. 4, the wires 2 of one of the layers are arranged with closer spacing than the wires 3 of the other layer. The section of the threads being identical for the two layers laid out in a cross.
Dans une autre variante, figure 5, le renforcement du produit maillé ou du média filtrant est réalisé seulement dans la partie la plus sollicitée aux efforts mécaniques, par une distribution non régulière des fils ou profilés de la structure de renfort. In another variant, in FIG. 5, the reinforcement of the meshed product or of the filtering medium is carried out only in the part most stressed by mechanical forces, by an irregular distribution of the wires or profiles of the reinforcing structure.
Dans les parties les plus chargées, au centre de la figure 4 les fils ou profilés 2 sont plus rapprochés que dans les parties latérales 5. In the most loaded parts, in the center of FIG. 4 the wires or profiles 2 are closer together than in the side parts 5.
Sans sortir du cadre de l'invention on peut aussi envisager un renfort de structure aux endroits les plus sollicités soit par augmentation de section des fils ou profilés de l'armature en conservant une répartition à pas constant, soit aussi en combinant augmentation de section des fils ou profilés de l'armature et resserrement du pas à ces endroits les plus sollicités à l'usage. Without departing from the scope of the invention, it is also possible to envisage a structural reinforcement in the most stressed places, either by increasing the cross-section of the wires or the profiles of the armature while maintaining a distribution with constant pitch, or also by combining an increase in cross-section of the wires or profiles of the reinforcement and tightening of the pitch at these places most in demand during use.
Il est bien entendu envisageable de combiner toutes les possibilités décrites ci-dessus, soit sur une nappe seulement, soit sur les deux nappes de l'armature de renfort, sans sortir du cadre de l'invention. It is of course conceivable to combine all the possibilities described above, either on one ply only, or on the two plies of the reinforcement, without departing from the scope of the invention.
Notons que dans le cas particulier de la réalisation d'une structure de renfort utilisant des fils de section ronde on évite la neutralisation d'une partie de la transparence, et par conséquent une perte de l'efficacité du produit maillé ou du média filtrant, caractéristique particulièrement appréciée dans les applications de séparation, tamisage, triage, filtration,etc. It should be noted that in the particular case of the production of a reinforcing structure using wires of round section, the neutralization of part of the transparency is avoided, and consequently a loss of the effectiveness of the mesh product or of the filtering medium, characteristic particularly appreciated in the applications of separation, sieving, sorting, filtration, etc.
Dans ce cas, on peut remarquer en effet que l'appui entre surface du produit maillé ou du média filtrant armé s'effectue seulement le long de la génératrice des fils ronds en contact avec le produit maillé ou le média filtrant armé. In this case, it can indeed be noted that the support between the surface of the mesh product or of the reinforced filter medium takes place only along the generator of the round wires in contact with the mesh product or the reinforced filter medium.
Le même résultat peut être obtenu en réalisant l'armature à partir de profilés de section triangulaire ou dont la section présente au moins une arête, figure 3. The same result can be obtained by making the reinforcement from profiles of triangular section or of which the section has at least one edge, FIG. 3.
L'appui de l'assemblage se fait non plus sur une génératrice du fil rond mais sur les arêtes du profilé au travers du produit maillé ou du média filtrant. The support of the assembly is no longer on a generator of the round wire but on the edges of the profile through the mesh product or the filter media.
Le produit maillé ou le média filtrant armé de l'invention est particulièrement bien adapté pour la réalisation de tous filtres ou cribles ou tamis dans lesquels on recherche à la fois une porosité ou transparence élevée et une rigidité associées ou non à une résistance mécanique élevée. The meshed product or the reinforced filter medium of the invention is particularly well suited for the production of all filters or screens or sieves in which both high porosity or transparency and a rigidity associated or not with high mechanical strength are sought.
Les caractéristiques du produit de l'invention permettent de réaliser des filtres, cribles ou tamis autoporteurs allégeant ainsi les structures de maintien. The characteristics of the product of the invention make it possible to produce self-supporting filters, screens or sieves thus reducing the support structures.
Le produit maillé armé de l'invention trouve également sa justification pour la réalisation, par exemple, de claies de séchage pour fruits, légumes, etc., ses qualités permettent d'obtenir la transparence élevée favorisant une bonne circulation de l'air, et la résistance mécanique renforcée autorisant la mise en oeuvre, sans autres structures de renfort, les panneaux de claie étant autoporteurs. The reinforced mesh product of the invention also finds its justification for the production, for example, of drying racks for fruits, vegetables, etc., its qualities make it possible to obtain high transparency promoting good air circulation, and the reinforced mechanical strength authorizing the implementation, without other reinforcing structures, the rack panels being self-supporting.
Le produit de l'invention est particulièrement bien adapté à toutes les utilisations qui réclament à la fois grande transparence et rigidité et/ou résistance mécanique élevée dans des applications de séparation ou de soutien. The product of the invention is particularly well suited to all uses which require both high transparency and rigidity and / or high mechanical strength in separation or support applications.
