Abstract

The abrasive item is composed of a metallic fiber mattress (1) which is wound on itself in several thickness (2a,2b,2c) about a longitudinal axis. The thicknesses are needled (4) together to reinforce their cohesion. An Independent claim is also included for the manufacturing process of an abrasive item.

Description

L'invention concerne un article abrasif, notamment pour le meulage, le brossage, le polissage, le lavage et/ou le nettoyage, par exemple, tampon, ainsi qu'un procédé et un dispositif pour la fabrication dudit article. The invention relates to an abrasive article, in particular for grinding, brushing, polishing, washing and / or cleaning, for example, a pad, as well as a method and a device for manufacturing said article.

Bien que plus particulièrement prévue pour les applications mentionnées au paragraphe précédent, l'invention pourra être utilisée dans tout autre domaine, où l'on requiert les qualités dudit article abrasif. Although more particularly intended for the applications mentioned in the preceding paragraph, the invention may be used in any other field, where the qualities of said abrasive article are required.

Actuellement, il est connu des tampons constitués d'un matelas de fibres métalliques entremêlées, notamment d'acier. Bien que satisfaisants quand il s'agit de les utiliser à la main, ces tampons restent difficiles à mettre en oeuvre par voie mécanique, par exemple, sur des ponceuses, polisseuses ou autres outils motorisés. En effet, compte tenu de leur faible cohésion, ils se délitent, se cassent, se déchirent et/ou produisent de la poussière en grande quantité. Currently, pads are known which consist of a mattress of intertwined metal fibers, in particular steel. Although satisfactory when it comes to using them by hand, these pads remain difficult to implement mechanically, for example, on sanders, polishers or other motorized tools. Indeed, given their low cohesion, they disintegrate, break, tear and / or produce dust in large quantities.

On est ainsi contraint d'employer avec de tels outils des feuilles de matériau abrasif telles que, par exemple, du papier de verre, plus résistant, mais dont le rendu est de moins bonne qualité. It is thus forced to use with such tools sheets of abrasive material such as, for example, sandpaper, more resistant, but whose rendering is of lower quality.

Le but de la présente invention est de proposer un article abrasif, notamment pour le meulage, le brossage, le polissage, le lavage et/ou le nettoyage, par exemple, tampon, à base de fibres métalliques qui pallie les inconvénients précités et présente une cohésion et une résistance mécanique améliorées. The object of the present invention is to provide an abrasive article, in particular for grinding, brushing, polishing, washing and / or cleaning, for example, a pad, based on metal fibers which overcomes the aforementioned drawbacks and has a improved cohesion and mechanical strength.

Un avantage de l'article abrasif conforme à l'invention est ainsi de pouvoir être monté sur des outils motorisés, notamment ponceuse, polisseuse ou autres. An advantage of the abrasive article in accordance with the invention is thus that it can be mounted on motorized tools, in particular a sander, a polisher or the like.

D'autres buts et avantages de l'invention apparaîtront au cours de la description qui va suivre qui n'est donnée qu'à titre indicatif et qui n'a pas pour but de la limiter. Other objects and advantages of the invention will appear during the description which follows which is given for information only and which is not intended to limit it.

L'invention concerne tout d'abord un article abrasif, notamment pour le meulage, le brossage, le polissage, le lavage et/ou le nettoyage, par exemple tampon, constitué d'un matelas de fibres métalliques, caractérisé par le fait que ledit matelas se présente sous la forme d'un enroulement sur lui- même en plusieurs épaisseurs, autour d'un axe longitudinal, lesdites épaisseurs étant aiguilletées entre elles afin de renforcer leur cohésion. The invention relates first of all to an abrasive article, in particular for grinding, brushing, polishing, washing and / or cleaning, for example a pad, consisting of a mattress of metallic fibers, characterized in that said mattress is in the form of a winding on itself in several thicknesses, around a longitudinal axis, said thicknesses being needled between them in order to reinforce their cohesion.

L'invention concerne également un procédé de fabrication d'un tel article dans lequel - on prévoit un matelas de fibres métalliques, - on enroule ledit matelas sur lui-même en plusieurs épaisseurs autour d'un axe longitudinal, - on aiguillette lesdites épaisseurs entre elles. The invention also relates to a method of manufacturing such an article in which - a mattress of metallic fibers is provided, - said mattress is wound on itself in several thicknesses around a longitudinal axis, - said thicknesses are spun between they.

L'invention concerne encore un dispositif de fabrication d'un article tel que celui décrit plus haut, comprenant - des moyens pour enrouler un matelas de fibres métalliques sur lui-même en plusieurs épaisseurs autour d'un axe longitudinal, - des moyens pour aiguilleter lesdites épaisseurs entre elles. L'invention sera mieux comprise à la lecture de la description suivante accompagnée des dessins en annexe qui en font partie intégrante et parmi lesquels - la figure 1 illustre, en vue de face, un exemple d'article conforme à l'invention, - la figure 2 est une vue de coupe d'après la ligne II-II représentée à la figure 1 précédente. The invention also relates to a device for manufacturing an article such as that described above, comprising - means for winding a mattress of metallic fibers around itself in several thicknesses around a longitudinal axis, - means for needling said thicknesses therebetween. The invention will be better understood on reading the following description accompanied by the accompanying drawings which form an integral part thereof and among which - FIG. 1 illustrates, in front view, an example of an article in accordance with the invention, - the Figure 2 is a sectional view along line II-II shown in Figure 1 above.

L'invention concerne un article abrasif, notamment pour le meulage, le brossage, le polissage, le lavage et/ou le nettoyage, par exemple tampon. The invention relates to an abrasive article, in particular for grinding, brushing, polishing, washing and / or cleaning, for example a pad.

Comme illustré aux figures 1 et 2, ledit article est constitué d'un matelas 1 de fibres métalliques, tel que notamment une nappe de fibres d'acier. Un tel matelas présente en lui-même de manière connue une certaine cohésion, mais faible, due à l'agrippage des fibres métalliques entre elles. As illustrated in Figures 1 and 2, said article consists of a mattress 1 of metal fibers, such as in particular a sheet of steel fibers. Such a mattress has in itself in a known manner a certain cohesion, but weak, due to the grasping of the metallic fibers between them.

Selon l'invention, afin de renforcer la cohésion dudit article, ledit matelas 1 se présente sous la forme d'un enroulement sur lui-même en plusieurs épaisseurs 2a, 2b, 2c, ... autour d'un axe longitudinal 3, fictif, lesdites épaisseurs étant aiguilletées entre elles. Par aiguilletées , on entend que lesdites épaisseurs ont subi, en une multitude de points, un percement par des aiguilles spéciales ou des organes équivalents, lesdites aiguilles ou organes équivalents étant ensuite retirés, permettant de la sorte un agrippage entre elles des fibres des différentes épaisseurs. According to the invention, in order to reinforce the cohesion of said article, said mattress 1 is in the form of a winding on itself in several thicknesses 2a, 2b, 2c, ... around a longitudinal axis 3, fictitious , said thicknesses being needled between them. By needled, it is meant that said thicknesses have undergone, at a multitude of points, a piercing by special needles or equivalent bodies, said needles or equivalent bodies being then removed, thereby allowing fibers of different thicknesses to be gripped together .

On peut aussi noter que, grâce audit enroulement, les fibres situées en surface de chaque épaisseur s'accrochent les unes aux autres d'une épaisseur à l'autre. On obtient ainsi un article plus résistant. It can also be noted that, thanks to said winding, the fibers located on the surface of each thickness cling to one another from one thickness to another. A more resistant article is thus obtained.

Ledit enroulement présente, par exemple, la forme d'un cylindre centré sur ledit axe longitudinal 3. La longueur dudit enroulement correspond, notamment, à la longueur dudit matelas tandis que sa hauteur correspond, par exemple, à la largeur dudit matelas. Said winding has, for example, the shape of a cylinder centered on said longitudinal axis 3. The length of said winding corresponds, in particular, to the length of said mattress while its height corresponds, for example, to the width of said mattress.

Les aiguilletages, repérés 4 et illustrés symboliquement en pointillés à la figure 2, sont prévus, notamment, sur toute la hauteur et/ou toute la circonférence dudit article. The needles, marked 4 and illustrated symbolically in dotted lines in FIG. 2, are provided, in particular, over the entire height and / or the entire circumference of said article.

Selon un mode de réalisation particulier, la profondeur d'aiguilletage est prévue sur au moins deux épaisseurs et les aiguilletages 4, sont successivement répartis tout le long dudit enroulement, au fur et à mesure de l'enroulement. According to a particular embodiment, the needling depth is provided over at least two thicknesses and the needles 4 are successively distributed all along said winding, as the winding progresses.

Lesdits aiguilletages sont répartis, notamment, à intervalles angulaires différents autour dudit axe longitudinal 3 d'une épaisseur dudit enroulement à l'épaisseur voisine. On évite ainsi que les aiguilletages des différentes épaisseurs ne se trouvent systématiquement dans le prolongement les uns des autres. Said needles are distributed, in particular, at different angular intervals around said longitudinal axis 3 from a thickness of said winding to the neighboring thickness. This avoids that the needles of different thicknesses are systematically in line with each other.

Lesdits aiguilletages 4 sont orientés, par exemple, selon des directions sensiblement concourantes, voire orthogonales, audit axe longitudinal. Dans le cas d'un article présentant une forme cylindrique, il s'agira alors d'aiguilletages radiaux. Said needles 4 are oriented, for example, in directions that are substantially concurrent, even orthogonal, to said longitudinal axis. In the case of an article having a cylindrical shape, it will then be radial needles.

L'invention concerne également un procédé de fabrication d'un article tel que décrit plus haut. Selon ledit procédé, on prévoit un matelas de fibres métalliques 1, on enroule ledit matelas sur lui-même en plusieurs épaisseurs 2a, 2b, 2c, ... autour d'un axe longitudinal 3 et on aiguillette lesdites épaisseurs entre elles, notamment sur toute la hauteur et/ou toute la circonférence dudit article. The invention also relates to a method of manufacturing an article as described above. According to said method, a mattress of metallic fibers 1 is provided, said mattress is wound on itself in several thicknesses 2a, 2b, 2c, ... around a longitudinal axis 3 and said thicknesses are spun together, in particular on the entire height and / or the entire circumference of said article.

Selon un mode particulier de mise en oeuvre, à chaque nouvelle épaisseur enroulée, on aiguillette ladite épaisseur avec l'épaisseur précédente. Plus précisément, à chaque nouvelle épaisseur enroulée, on pourra décaler angulairement autour dudit axe longitudinal 3 les zones dudit article où l'on aiguillette les épaisseurs. According to a particular mode of implementation, with each new thickness wound, the said thickness is needled with the previous thickness. More precisely, with each new thickness wound, it is possible to offset angularly around said longitudinal axis 3 the zones of said article where the thicknesses are needled.

On pourra enrouler ledit matelas 1, par exemple prévu sensiblement en forme de nappe de section quadrangulaire, notamment rectangulaire, à partir de l'un de ses bords 5. Said mattress 1 can be rolled up, for example provided substantially in the form of a ply of quadrangular section, in particular rectangular, from one of its edges 5.

On pourra encore prévoir d'enrouler ledit matelas sur lui-même pour former un article d'hauteur h supérieure à la largeur dudit matelas. Pour cela, on enroulera ledit matelas sur lui-même selon un mouvement hélicoïdal présentant un pas inférieur à la largeur dudit matelas et selon un mouvement de va et vient le long de l'axe longitudinal dudit article. Provision may also be made to roll up said mattress on itself to form an article of height h greater than the width of said mattress. For this, said mattress will be wound on itself in a helical movement having a pitch less than the width of said mattress and in a back and forth movement along the longitudinal axis of said article.

L'invention concerne également un dispositif de fabrication d'un article tel que celui décrit plus haut. II comprend des moyens pour enrouler un matelas 1 de fibres métalliques sur lui-même en plusieurs épaisseurs 2a, 2b, 2c, ... autour d'un axe longitudinal 3 et des moyens pour aiguilleter lesdites épaisseurs entre elles, notamment au fur et à mesure de l'enroulement. The invention also relates to a device for manufacturing an article such as that described above. It comprises means for winding a mattress 1 of metallic fibers around itself in several thicknesses 2a, 2b, 2c, ... around a longitudinal axis 3 and means for spurring said thicknesses together, in particular as and when winding measurement.

Lesdits moyens pour enrouler sont constitués, par exemple, d'un mandrin, apte à être entraîné selon une vitesse de rotation lente. Said means for winding consist, for example, of a mandrel, capable of being driven at a slow speed of rotation.

Ledit mandrin sera éventuellement bordé à chacune de ses extrémités longitudinales d'un disque permettant de retenir ledit article au cours de sa formation. Said mandrel will optionally be bordered at each of its longitudinal ends with a disc enabling said article to be retained during its formation.

Ledit mandrin est en outre prévu, par exemple, à permettre la fixation de l'un des bords 5 du matelas, notamment prévu quadrangulaire, par exemple rectangulaire. Said mandrel is further provided, for example, to allow the fixing of one of the edges 5 of the mattress, in particular provided quadrangular, for example rectangular.

Naturellement, d'autres modes de mise en oeuvre, à la portée de l'homme de l'art, auraient pu être envisagés sans pour autant sortir du cadre de l'invention. Par exemple, les fibres métalliques pourraient être mélangées avec d'autres fibres textiles ou synthétiques, selon l'effet abrasif recherché, ou les effets complémentaires visés.Naturally, other modes of implementation, within the reach of those skilled in the art, could have been envisaged without departing from the scope of the invention. For example, the metallic fibers could be mixed with other textile or synthetic fibers, depending on the abrasive effect sought, or the complementary effects targeted.
