Description

DISPOSITIF POUR LE PONÇAGE OU LE POLISSAGE COMPORTANT UN SUPPORT PRESENTANT UNE SURFACE A ADHERENCE RENOUVELABLE. DEVICE FOR SANDING OR POLISHING COMPRISING A SUPPORT HAVING A RENEWABLE ADHESIVE SURFACE.
La présente invention se rapporte au domaine du ponçage ou du polissage.The present invention relates to the field of sanding or polishing.
La présente invention se rapporte plus particulièrement à un dispositif pour le ponçage ou le polissage du type comportant un support, susceptible d'être entraîné en mouvement, présentant une première surface d'extrémité contre laquelle peut être positionnée une feuille de ponçage ou de polissage présentant une face intérieure destinée à être positionnée contre ladite première surface d'extrémité dudit support et une face extérieure de ponçage ou de polissage, ledit dispositif comportant des moyens de retenu de ladite feuille.The present invention relates more particularly to a device for sanding or polishing of the type comprising a support, capable of being driven in movement, having a first end surface against which can be positioned a sanding or polishing sheet having an inner face intended to be positioned against said first end surface of said support and an outer sanding or polishing face, said device comprising means for retaining said sheet.
Ces moyens de retenu permettent de retenir la feuille pendant le ponçage ou le polissage et permettent également de changer la feuille par une autre feuille lorsque la première est usée.These retaining means make it possible to retain the sheet during sanding or polishing and also allow the sheet to be changed by another sheet when the first is worn.
L'art antérieur connaît déjà des dispositifs pour le ponçage ou le polissage comportant un support et des moyens de retenu de la feuille de ponçage ou de polissage.The prior art already knows devices for sanding or polishing comprising a support and means for retaining the sanding or polishing sheet.
Il est connu, par exemple de réaliser des ponceuses électriques vibrantes présentant des tiges flexibles permettant de maintenir par pressage les extrémités de la feuille de ponçage ou de polissage en opérant, en dehors de la surface de ponçage ou de polissage une pression contre elles.It is known, for example, to produce electric vibrating sanders having flexible rods making it possible to maintain by pressing the ends of the sanding or polishing sheet while operating, outside the sanding or polishing surface, pressure against them.
Un inconvénient de ce type de fixation est qu'il est difficile de manier ces tiges flexibles sans endommager la feuille de ponçage ou de polissage. En outre, les extrémités de la feuille qui servent à bloquer la feuille contre la première surface d'extrémité du support ne peuvent pas être utilisées pour le ponçage ou le polissage. Enfin, si la feuille de ponçage ou de polissage est effectivement fixée sur le support du dispositif, elle n'est pas maintenue plaquée contre la première surface d'extrémité du support et cela engendre une perte d'efficacité importante lors du ponçage ou du polissage.A disadvantage of this type of attachment is that it is difficult to handle these flexible rods without damaging the sanding or polishing sheet. In addition, the ends of the sheet which serve to block the sheet against the first end surface of the support. cannot be used for sanding or polishing. Finally, if the sanding or polishing sheet is effectively fixed on the support of the device, it is not kept pressed against the first end surface of the support and this generates a significant loss of efficiency during sanding or polishing. .
L'art antérieur connaît également, par exemple, les demandes de brevet européen N° EP 868 261, N° EP 886 557 et N° EP 729 807, ainsi que la demande de brevet allemand N° DE 42 41 890. Ces documents présentent chacun un dispositif pour le ponçage ou le polissage du type comportant un support, susceptible d'être entraîné en mouvement, présentant une surface d'extrémité contre laquelle peut être positionnée une feuille de ponçage ou de polissage présentant une face intérieure destinée à être positionnée contre ladite surface d'extrémité dudit support et une face extérieure de ponçage ou de polissage, ledit dispositif comportant des moyens de retenu de ladite feuille. Ces moyens de retenu sont constitués par une couche adhésive, prévue sur la face intérieure de la feuille de ponçage. Cette couche adhésive l'adhérence permet de détacher la feuille de ponçage utilisée et de la changer lorsqu'elle est usée.The prior art also knows, for example, European patent applications N ° EP 868 261, N ° EP 886 557 and N ° EP 729 807, as well as German patent application N ° DE 42 41 890. These documents present each a device for sanding or polishing of the type comprising a support, capable of being driven in movement, having an end surface against which can be positioned a sanding or polishing sheet having an inner face intended to be positioned against said end surface of said support and an external sanding or polishing face, said device comprising means for retaining said sheet. These retaining means consist of an adhesive layer, provided on the inside of the sanding sheet. This adhesion adhesive layer makes it possible to detach the sanding sheet used and to change it when it is worn.
Il a également été proposé dans l'art antérieur de réaliser des picots sur la première surface d'extrémité du support et de réaliser des boucles de fils sur la face intérieure de la feuille de polissage ou de ponçage, l'adhérence entre la première surface d'extrémité et la face intérieure étant ainsi réalisée selon le principe des bandes auto-agrippantes Velcro (marque déposée) .It has also been proposed in the prior art to make pins on the first end surface of the support and to make loops of wires on the inside of the polishing or sanding sheet, the adhesion between the first surface end and the inner face thus being produced according to the principle of Velcro hook and loop strips (registered trademark).
Ce genre de fixation, bien que n'engendrant pas de perte de matière inutilisée aux extrémités de la feuille, présente l'inconvénient majeur d'augmenter d'une manière importante le coût de la feuille de ponçage ou de polissage. En outre, l'adhérence ainsi réalisée ne présente pas toujours la fiabilité requise. La feuille n'est pas parfaitement adhérente contre la première surface d'extrémité du support et présente un certain jeu par rapport au support lorsque le support est entraîné en mouvement. De plus, bien que permettant de maintenir la surface intérieure de la feuille sensiblement contre la première surface d'extrémité du support, l'interface des picots avec les boucles engendre, lors du passage de la feuille sur une arête ou une crête du matériau à poncer ou à polir, un enfoncement localisé de la feuille de polissage ou de ponçage, ce qui diminue l'efficacité de la feuille et provoque une usure prématurée de la feuille.This type of attachment, although not causing loss of unused material at the ends of the sheet, has the major drawback of significantly increasing the cost of the sanding or polishing sheet. In addition, the adhesion thus produced does not present not always the reliability required. The sheet is not perfectly adherent against the first end surface of the support and has a certain play with respect to the support when the support is driven in movement. In addition, although allowing the interior surface of the sheet to be held substantially against the first end surface of the support, the interface of the pins with the loops generates, when the sheet passes over an edge or a ridge of the material to be sand or polish, a localized depression of the polishing or sanding sheet, which reduces the effectiveness of the sheet and causes premature wear of the sheet.
L'art antérieur par ailleurs la demande de brevet français N° FR 2 755 445. Ce document porte sur un article multicouche adhésif repositionnable comportant une couche adhésive en polyuréthanne. Grâce à cette couche, l'article peut être positionné à un endroit, puis enlevé et positionné au même endroit ou à un autre endroit.The prior art furthermore French patent application No. FR 2 755 445. This document relates to a repositionable adhesive multilayer article comprising an adhesive layer of polyurethane. Thanks to this layer, the article can be positioned in one place, then removed and positioned in the same place or in another place.
Il pourrait être imaginé d'utiliser une telle couche adhésive sur la face intérieure d'une feuille de ponçage ou de polissage, mais cela augmenterait considérablement le coût de la feuille de ponçage ou de polissage.It could be imagined to use such an adhesive layer on the inner face of a sanding or polishing sheet, but this would considerably increase the cost of the sanding or polishing sheet.
La présente invention entend remédier aux inconvénients de l'art antérieur en proposant un dispositif qui permette de ne prévoir aucun moyen d'adhérence particulier sur la face intérieure de la feuille de ponçage ou de polissage, qui n'engendre pas de perte de matière de la feuille et qui permette une parfaite adhérence de la feuille contre la première surface d'extrémité du support, tout en autorisant bien évidemment la substitution d'une feuille par une autre chaque fois que cela est nécessaire.The present invention intends to remedy the drawbacks of the prior art by proposing a device which makes it possible to provide no particular adhesion means on the inner face of the sanding or polishing sheet, which does not cause loss of material. the sheet and which allows perfect adhesion of the sheet against the first end surface of the support, while obviously allowing the substitution of one sheet for another whenever necessary.
Pour ce faire, la présente invention est du type décrit ci-dessus et elle est remarquable, dans son acception la plus large, en ce que lesdits moyens de retenu sont constitués d'une surface positionnée contre une première surface d'extrémité et permettant une adhérence renouvelable par nettoyage de ladite couche à adhérence renouvelable .To do this, the present invention is of the type described above and it is remarkable, in its broadest sense, in that said retaining means consist of a surface positioned against a first end surface and allowing a renewable adhesion by cleaning said layer with renewable adhesion.
Ledit support comporte en outre de préférence des moyens d'attache d'un bord de ladite feuille afin de permettre de réaliser au moins un bord d'attaque de ponçage ou de polissage lorsque ledit support est entraîné en mouvement .Said support further preferably comprises means for attaching an edge of said sheet in order to allow at least one leading edge of sanding or polishing to be produced when said support is driven in movement.
Dans une variante de l'invention, ladite surface à adhérence renouvelable est de préférence constituée d'une couche de colle réactivable.In a variant of the invention, said surface with renewable adhesion preferably consists of a layer of reactivable adhesive.
Ladite couche de colle réactivable est de préférence du type colle vinylique activable à l'eau.Said layer of reactivatable adhesive is preferably of the vinyl adhesive type which can be activated with water.
Dans une autre variante de l'invention, ladite surface à adhérence renouvelable est de préférence constituée d'une couche de polymère adhérant.In another variant of the invention, said surface with renewable adhesion preferably consists of a layer of adhering polymer.
Ladite couche de polymère adhérant est de préférence à base essentiellement de polyuréthane, telle que celle connue de la demande de brevet français FR 2 755 445, incorporée ici par voie de référence.Said adhering polymer layer is preferably based essentially on polyurethane, such as that known from French patent application FR 2 755 445, incorporated herein by reference.
! L'adhérence est ainsi renouvelable par simple nettoyage avec de l'eau de la couche de polymère. ! The adhesion is thus renewable by simple cleaning with water of the polymer layer.
Dans une autre variante de l'invention compatible avec les précédentes, ledit support est réalisé en matériau déformable manuellement.In another variant of the invention compatible with the previous ones, said support is made of manually deformable material.
Ce matériau déformable manuellement est, par exemple, un treillis constitué de fils métalliques.This manually deformable material is, for example, a trellis made of metal wires.
Le dispositif selon l'invention comporte, de préférence une seconde surface d'extrémité, opposée à ladite première surface d'extrémité.The device according to the invention preferably comprises a second end surface, opposite to said first end surface.
Dans une variante, ladite seconde surface d'extrémité comportant une couche permettant une adhérence renouvelable par nettoyage de ladite couche à adhérence renouvelable .In a variant, said second end surface comprising a layer allowing adhesion renewable by cleaning said layer with renewable adhesion.
Dans une autre variante importante de l'invention, le dispositif constitue un accessoire permettant d'adapter le principe de l'adhérence renouvelable par nettoyage selon l'invention à une ponceuse ou une polisseuse présentant un patin présentant sur une surface d'extrémité au moins une bande de matériau à bouclette ou de matériau à crochets, de type Velcro. Dans cette variante, ladite seconde surface d'extrémité comporte au moins une bande de matériau à bouclette ou de matériau à crochets, de type Velcro, afin de permettre ainsi la fixation de la feuille de ponçage sur ledit dispositif et la fixation dudit dispositif au patin de la ponceuse ou de la polisseuse.In another important variant of the invention, the device constitutes an accessory making it possible to adapt the principle of renewable adhesion by cleaning according to the invention to a sander or a polisher having a pad having on at least one end surface a strip of loop material or hook material, Velcro type. In this variant, said second end surface comprises at least one strip of loop material or hook material, of Velcro type, so as to allow the fixing of the sanding sheet on said device and the fixing of said device to the pad. sander or polisher.
Dans cette variante importante de l'invention, ladite seconde surface d'extrémité comporte, de préférence, sur la totalité de sa surface un matériau à bouclette ou un matériau à crochets .In this important variant of the invention, said second end surface preferably comprises over its entire surface a loop material or a hook material.
La présente invention se rapporte également à une ponceuse et notamment une ponceuse électrique, ainsi qu'à une polisseuse et notamment une polisseuse électrique, comportant un dispositif selon l'invention.The present invention also relates to a sander and in particular an electric sander, as well as to a polisher and in particular an electric polisher, comprising a device according to the invention.
La présente invention se rapporte également à un procédé d'utilisation du dispositif selon l'invention dans lequel on fixe la face intérieure de la feuille de ponçage ou de polissage contre la couche de la première surface d'extrémité du support par adhérence renouvelableThe present invention also relates to a method of using the device according to the invention in which the inner face of the sanding or polishing sheet is fixed against the layer of the first end surface of the support by renewable adhesion.
I par nettoyage de ladite couche à adhérence renouvelable .I by cleaning said layer with renewable adhesion.

L'avantage majeur procuré par la présente invention est que la feuille de ponçage ou polissage ne présente aucun moyen particulier pour faciliter son adhérence contre le support ; ainsi, aucun coût supplémentaire n'est engendré lors de la fabrication de cette feuille.The major advantage provided by the present invention is that the sanding or polishing sheet has no particular means to facilitate its adhesion against the support; thus, no additional cost is generated during the manufacture of this sheet.
Avantageusement, grâce à la surface à adhérence renouvelable selon l'invention, il est très facile de positionner une feuille de ponçage ou de polissage contre la première surface d'extrémité du support. La feuille de ponçage ou de polissage est parfaitement maintenue contre la première surface d'extrémité du support lorsque le dispositif est soumis à un mouvement de rotation ou de translation. La feuille de ponçage ou de polissage est par ailleurs très facile à retirer et à remplacer par une autre feuille de ponçage ou de polissage dès que la première est usée ou lorsque souhaité. L'adhérence renouvelable permet de retrouver une nouvelle adhérence, identique à une adhérence neuve, à chaque fois que cela est nécessaire.Advantageously, thanks to the surface with renewable adhesion according to the invention, it is very easy to position a sanding or polishing sheet against the first end surface of the support. The sanding or polishing sheet is perfectly held against the first end surface of the support when the device is subjected to a rotational or translational movement. The sanding or polishing sheet is also very easy to remove and replace with another sanding or polishing sheet as soon as the first is worn or when desired. Renewable adhesion allows to find a new adhesion, identical to a new adhesion, whenever necessary.
Du fait que l'adhérence est renouvelable, les éventuels dépôts de matière ou poussière contre la première surface d'extrémité du support peuvent être évacués avant la première utilisation ou lors du renouvellement de l'adhérence, par simple nettoyage de la couche à adhérence renouvelable .Because the adhesion is renewable, any deposits of material or dust against the first end surface of the support can be removed before the first use or when renewing the adhesion, by simply cleaning the layer with renewable adhesion. .
Aucune matière n'est ajoutée à cette couche lors du renouvellement de l'adhérence et l'ensemble du dispositif conserve ses caractéristiques de transmission du mouvement de ponçage ou de polissage à la feuille de ponçage ou de polissage. On comprendra mieux l'invention à l'aide de la description, faite ci-après à titre purement explicatif, d'un mode de réalisation de l'invention, en référence aux figures annexées : la figure 1 illustre une vue en perspective une version de base du dispositif selon l'invention ; la figure 2 illustre en perspective d'une version du dispositif selon l'invention à support circulaire ; la figure 3 illustre une vue en perspective d'une version du dispositif selon l'invention à élément de retenu facultatif ; les figures 4 et 5 illustrent en perspective une variante du dispositif selon l'invention à support cylindrique ; la figure 6 illustre une vue en perspective de la déformation du support selon l'invention en fonction de la configuration de l'élément à poncer ; la figure 7 illustre une vue en perspective de la variante de réalisation dans laquelle le dispositif constitue un accessoire permettant d'adapter le principe de l'adhérence renouvelable par nettoyage selon l'invention à une ponceuse ou une polisseuse présentant un patin présentant sur sa face inférieure une bande de matériau à bouclette ou de matériau à crochets, de type Velcro ; et la figure 8 illustre une vue en perspective d'une version du dispositif selon l'invention à deux surfaces d'extrémité opposées présentant chacune une couche à adhérence renouvelable.No material is added to this layer when the adhesion is renewed and the entire device retains its characteristics of transmission of the sanding or polishing movement to the sanding or polishing sheet. The invention will be better understood with the aid of the description, given below for purely explanatory purposes, of an embodiment of the invention, with reference to the appended figures: FIG. 1 illustrates a perspective view a version of the device according to the invention; Figure 2 illustrates in perspective a version of the device according to the invention with circular support; FIG. 3 illustrates a perspective view of a version of the device according to the invention with an optional retaining element; Figures 4 and 5 illustrate in perspective a variant of the device according to the invention with cylindrical support; FIG. 6 illustrates a perspective view of the deformation of the support according to the invention as a function of the configuration of the element to be sanded; FIG. 7 illustrates a perspective view of the alternative embodiment in which the device constitutes an accessory making it possible to adapt the principle of renewable adhesion by cleaning according to the invention to a sander or a polisher having a pad having on its face lower a strip of loop material or hook material, Velcro type; and FIG. 8 illustrates a perspective view of a version of the device according to the invention with two opposite end surfaces each having a layer with renewable adhesion.
Le dispositif (1) selon l'invention, illustré figure 1, est un dispositif pour le ponçage ou le polissage du type comportant un support (2) ou patin, susceptible d'être entraîné en mouvement par actionnement manuel ou par actionnement mécanique.The device (1) according to the invention, illustrated in FIG. 1, is a device for sanding or polishing of the type comprising a support (2) or pad, capable of to be driven in movement by manual actuation or by mechanical actuation.
Pour son actionnement manuel, le support (2) peut être pourvu d'une poignée et pour son actionnement mécanique, il peut être pourvu de moyens de fixation permettant de le fixer à un système de bielles entraînées à l'aide d'un moteur, comme par exemple un moteur électrique. Le support (2) peut ainsi constituer le patin d'une ponceuse à moteur électrique ou d'une polisseuse à moteur électrique .For its manual actuation, the support (2) can be provided with a handle and for its mechanical actuation, it can be provided with fixing means making it possible to fix it to a system of connecting rods driven by means of a motor, like for example an electric motor. The support (2) can thus constitute the pad of an electric motor sander or an electric motor polisher.
Le support (2) présente une première surface d'extrémité (3) contre laquelle peut être positionnée une feuille (4) ou une bande de ponçage ou de polissage présentant une face intérieure (5) destinée à être positionnée contre ladite première surface d'extrémité (3) dudit support (2) et une face extérieure (6) de ponçage ou de polissage.The support (2) has a first end surface (3) against which can be positioned a sheet (4) or a sanding or polishing strip having an inner face (5) intended to be positioned against said first surface. end (3) of said support (2) and an external face (6) of sanding or polishing.
Ledit dispositif (1) comporte en outre des moyens de retenu de ladite feuille (4) .Said device (1) further comprises means for retaining said sheet (4).
Le support (2) , constituant dans la version de base de l'invention, le patin de la ponceuse ou de la polisseuse, peut présenter une forme de brique droite, comme illustré figure 1, ou de disque circulaire, comme illustré figure 2, ou encore de cylindre droit, voire non droit, comme illustré figures 4 et 5.The support (2), constituting in the basic version of the invention, the pad of the sander or of the polisher, may have a shape of straight brick, as illustrated in FIG. 1, or of circular disc, as illustrated in FIG. 2, or a straight cylinder, even a non-straight cylinder, as illustrated in FIGS. 4 and 5.
Le dispositif (1) selon l'invention est caractérisé en ce que lesdits moyens de retenu sont constitués d'une couche (7) positionnée contre la première surface d'extrémité (3) et permettant une adhérence renouvelable par nettoyage de ladite couche (7) à adhérence renouvelable .The device (1) according to the invention is characterized in that said retaining means consist of a layer (7) positioned against the first end surface (3) and allowing a renewable adhesion by cleaning said layer (7 ) with renewable adhesion.
II
Ledit support (2) comporte en outre des moyens d'attache (8) d'un bord de ladite feuille afin de permettre de réaliser au moins un bord d'attaque (9) de ponçage ou de polissage lorsque ledit support (2) est entraîné en mouvement M, comme illustré figure 3, 4 et 5.Said support (2) further comprises means for attaching (8) an edge of said sheet in order to allow at least one leading edge (9) of sanding or polishing when said support (2) is driven in movement M, as illustrated in FIGS. 3, 4 and 5.
Ces moyens d'attache (8) peuvent être constitués, par exemple par une fente dans laquelle il est possible de glisser le bord de la feuille (4) .These attachment means (8) can be constituted, for example by a slot in which it is possible to slide the edge of the sheet (4).
En effet, dans certaines circonstances, notamment lorsque la surface à poncer ou à polir présente une rugosité importante, il est possible que le bord de la feuille (4) se décolle de la couche (7) .Indeed, in certain circumstances, in particular when the surface to be sanded or polished has a significant roughness, it is possible that the edge of the sheet (4) comes off the layer (7).
Dans une première variante de l'invention, ladite couche (7) à adhérence renouvelable est constituée d'une couche de colle réactivable.In a first variant of the invention, said layer (7) with renewable adhesion consists of a layer of reactivable adhesive.
Cette couche de colle réactivable peut être du type colle vinylique activable à l'eau ; la réactivation de la couche de liant permettant en outre, lorsque cela est nécessaire, de procéder au nettoyage de la surface à adhérence renouvelable .This reactivable adhesive layer can be of the vinyl adhesive type which can be activated with water; reactivation of the binder layer which also makes it possible, when necessary, to clean the surface with renewable adhesion.
II
Dans une deuxième variante de l'invention, ladite couche (7) à adhérence renouvelable est constituée d'une couche de polymère adhérant.In a second variant of the invention, said layer (7) with renewable adhesion consists of a layer of adhering polymer.
Ladite couche de polymère adhérant peut être à base essentiellement de polyuréthane .Said adhering polymer layer may be based essentially on polyurethane.
Une telle matière présente une adhérence qu' il est possible de renouveler en nettoyant la surface avec de l'eau. Cette opération permet en outre, lorsque cela est nécessaire, de procéder au nettoyage de la surface à adhérence renouvelable.Such a material has an adhesion which can be renewed by cleaning the surface with water. This operation also makes it possible, when necessary, to clean the surface with renewable adhesion.
Pour chacune des variantes, ledit support (2) peut être réalisé en matériau déformable manuellement. Ce matériau peut être, par exemple un alliage d'aluminium. Ce matériau peut être également un treillis constitué de fils métalliques. Il peut même être imaginé que le treillis soit constitué de fils de grosseurs différentes selon la chaîne ou la trame, afin de pouvoir être déformé plus facilement selon certaines surfaces réglées. ι II est alors possible de configurer le support (2) de manière à ce qu'il présente exactement la forme voulue. La figure 6 illustre ainsi le cas où le support (2) est configuré manuellement de manière à présenter suivant son profil longitudinal la forme exacte de la moitié gauche environ d'une rampe (10) d'escalier, comme illustré par la flèche F.For each variant, said support (2) can be made of manually deformable material. This material can be, for example an aluminum alloy. This material can also be a trellis made of metal wires. It can even be imagined that the trellis is made up of threads of different sizes depending on the warp or weft, so that it can be more easily deformed according to certain adjusted surfaces. ι It is then possible to configure the support (2) so that it has exactly the desired shape. FIG. 6 thus illustrates the case where the support (2) is manually configured so as to present, according to its longitudinal profile, the exact shape of approximately the left half of a staircase ramp (10), as illustrated by the arrow F.
Une fois que le support (10) présente la forme voulue, il suffit de renouveler l'adhérence et de positionner la feuille de ponçage. Le ponçage de la rampe (10) est beaucoup plus facile à réaliser avec un dispositif (1) comportant un support (2) configurable à souhait qu'avec un dispositif (1) comportant un support (2) entièrement rigide et non configurable.Once the support (10) has the desired shape, it suffices to renew the adhesion and to position the sanding sheet. Sanding the ramp (10) is much easier to carry out with a device (1) comprising a support (2) which can be configured as desired than with a device (1) comprising a support (2) which is entirely rigid and not configurable.
La matière du support (2) est de préférence choisie afin de permettre autant de reconfiguration que souhaité.The support material (2) is preferably chosen to allow as much reconfiguration as desired.
Il est par ailleurs possible d'imaginer que le support (2) présente une grande souplesse et se présente sous la forme d'un tapis.It is also possible to imagine that the support (2) has great flexibility and is in the form of a carpet.
Dans une variante importante, illustré figure 7, le dispositif (1) constitue un accessoire permettant d'adapter le principe de l'adhérence renouvelable par nettoyage selon l'invention à une ponceuse ou une polisseuse présentant un patin (20) présentant sur une surface d'extrémité (23) au moins une bande de matériau à bouclette (15) ou au moins une bande de matériau à crochets (17), de type Velcro. La surface d'extrémité (23) peut comporter sur la totalité de sa surface un matériau à bouclette (15) ou un matériau à crochets (17) . Dans la version illustrée figure 7, la surface d'extrémité (23) comporte sur la totalité de sa surface un matériau à crochets (17) .In an important variant, illustrated in FIG. 7, the device (1) constitutes an accessory making it possible to adapt the principle of renewable adhesion by cleaning according to the invention to a sander or a polisher having a pad (20) having on a surface end (23) at least one strip of loop material (15) or at least one strip of hook material (17), of Velcro type. The end surface (23) may comprise over its entire surface a loop material (15) or a hook material (17). In the version illustrated in FIG. 7, the end surface (23) comprises over its entire surface a material with hooks (17).
Dans cette variante, le dispositif (1) comporte t une seconde surface d'extrémité (13), opposée à ladite première surface d'extrémité (3), ladite seconde surface d'extrémité (13) comportant au moins une bande de matériau à bouclette (15) ou au moins une bande de matériau à crochets (17) , de type Velcro, cette bande étant destinée à coopérer avec la bande complémentaire du patin (2) .In this variant, the device (1) comprises a second end surface (13), opposite to said first end surface (3), said second end surface (13) comprising at least one strip of material to be loop (15) or at least one strip of hook material (17), of Velcro type, this strip being intended to cooperate with the complementary strip of the shoe (2).
Dans la version illustrée figure 7, ladite seconde surface d'extrémité (13) comporte sur la totalité de sa surface un matériau à bouclette (15) .In the version illustrated in Figure 7, said second end surface (13) comprises over its entire surface a loop material (15).
Dans une autre importante, illustré figure 8, le dispositif (1) comporte également une seconde surface d'extrémité (13), opposée à ladite première surface d/ extrémité (3), mais dans cette variante, ladite seconde surface d'extrémité (13) comporte une couche (7') permettant une adhérence renouvelable par nettoyage de ladite couche à adhérence renouvelable, afin de faciliter la préhension manuelle. Ainsi, il n'est pas nécessaire de prévoir sur le support (2) de moyens tels que des sangles, des brides ou des plots pour permettre de tenir fermement le support (2) avec les mains ; il suffit de mettre en contact les mains sur la couche (7') lorsque cette couche est propre pour que le support (2) adhère aux mains.In another important one, illustrated in FIG. 8, the device (1) also comprises a second end surface (13), opposite to said first end surface (3), but in this variant, said second end surface ( 13) comprises a layer (7 ′) allowing renewable adhesion by cleaning said layer with renewable adhesion, in order to facilitate manual gripping. Thus, it is not necessary to provide on the support (2) means such as straps, flanges or studs to allow the support (2) to be held firmly with the hands; it suffices to put the hands in contact with the layer (7 ′) when this layer is clean so that the support (2) adheres to the hands.
Pour la première utilisation du dispositif selon l'invention, si la couche (7) du support (2) est propre, il suffit de présenter la face intérieure (5) de la feuille (4) en vis-à-vis de la première surface d'extrémité (3) et de presser cette face intérieure (5) contre la couche (7) de la première surface d'extrémité (3). La première adhérence est ainsi obtenue par simple pression. Toutefois, si la couche (7) du support (2) n'est pas propre, l'adhérence de la feuille (4) sera mal assurée, voire ne sera pas du tout assurée. Pour provoquer l'adhérence de la couche (7), il suffit de la nettoyer avec de l'eau. Après séchage de la couche (7), celle-ci présente une nouvelle adhérence, identique à l'adhérence d'un dispositif neuf et propre et il suffit alors de presser la face intérieure (5) de la feuille (4) contre la couche (7) de la première surface d'extrémité (3) pour que la feuille (4) adhère parfaitement au support (2) .For the first use of the device according to the invention, if the layer (7) of the support (2) is clean, it suffices to present the inner face (5) of the sheet (4) opposite the first end surface (3) and pressing this inner face (5) against the layer (7) of the first end surface (3). The first adhesion is thus obtained by simple pressure. However, if the layer (7) of the support (2) is not clean, the adhesion of the sheet (4) will be poorly assured, or even will not be at all assured. To cause adhesion of the layer (7), it suffices to clean it with water. After the layer (7) has dried, it has a new adhesion, identical to the adhesion of a new and clean device and it then suffices to press the inner face (5) of the sheet (4) against the layer. (7) of the first end surface (3) so that the sheet (4) adheres perfectly to the support (2).
Lorsque l'on souhaite substituer une feuille (4) par une autre feuille (4), il faut d'abord enlever la première feuille (4), puis nettoyer la couche (7) avec de l'eau et ensuite, après séchage de la couche (7), il suffit alors de presser la face intérieure (5) de la feuille (4) contre la couche (7) de la première surface d'extrémité (3) pour que la feuille (4) adhère parfaitement au support (2) .When you want to replace a sheet (4) with another sheet (4), you must first remove the first sheet (4), then clean the layer (7) with water and then, after drying the layer (7), it suffices to press the inner face (5) of the sheet (4) against the layer (7) of the first end surface (3) so that the sheet (4) adheres perfectly to the support (2).
Pour la première utilisation du dispositif (1) selon l'invention lorsque le dispositif constitue un accessoire permettant d'adapter le principe de l'adhérence renouvelable par nettoyage selon l'invention à une ponceuse ou une polisseuse présentant un patin (20) présentant sur une surface d'extrémité (23) au moins une bande de matériau à bouclette (15) ou au moins une bande de matériau à crochets (17), de type Velcro, on fixe la bande (15, 17) de la seconde surface d'extrémité (13) du support (2) contre la bande (17, 15) de la surface d'extrémité (23) du patin (20) .For the first use of the device (1) according to the invention when the device constitutes an accessory making it possible to adapt the principle of renewable adhesion by cleaning according to the invention to a sander or a polisher having a pad (20) having on an end surface (23) at least one strip of loop material (15) or at least one strip of hook material (17), of Velcro type, the strip (15, 17) of the second surface is fixed end (13) of the support (2) against the strip (17, 15) of the end surface (23) of the shoe (20).
La couche (7) du dispositif (1) peut alors être utilisée comme expliqué précédemment.The layer (7) of the device (1) can then be used as explained above.
L'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de l'invention sans pour autant sortir du cadre du brevet. The invention is described in the foregoing by way of example. It is understood that the skilled person is at even realize different variants of the invention without departing from the scope of the patent.
