Abstract

The present invention relates to a mask for protecting a convex and/or window portion of a vehicle, the mask being made of a sheet material, and having an outline that is curvilinear, at least in part. A device for masking convex and/or window portions of motor vehicles is also provided having a plurality of masks that are united to form a packet of masks.

Description

La présente invention est relative à un procédé et à un dispositif de masquage d'une partie d'un véhicule automobile, afin de protéger cette partie de salissures susceptibles de résulter de la peinture d'une autre partie de ce véhicule.The present invention relates to a method and a device for masking a part of a motor vehicle, in order to protect this part of soiling that may result from the painting of another part of this vehicle.

Le domaine technique de l'invention est celui de la réparation de carrosserie automobile.The technical field of the invention is that of automotive body repair.

Il est connu de protéger les parties vitrées d'un véhicule automobile avant de peindre une partie au moins de la carrosserie, avec des masques recouvrant ces parties vitrées.It is known to protect the glass parts of a motor vehicle before painting at least part of the body, with masks covering these glass parts.

Par « partie vitrée », on entend essentiellement les parties non peintes du véhicule, en particulier le pare-brise, la lunette arrière, les vitres latérales gauche et droite, les optiques de phares et de feux arrière, les rétroviseurs extérieurs, ainsi que d'autres pièces telles que les roues, enjoliveurs de roue ou pare-chocs."Glass part" means essentially the unpainted parts of the vehicle, in particular the windscreen, the rear window, the left and right side windows, the headlight and taillight optics, the exterior rear-view mirrors and other parts such as wheels, hubcaps or bumpers.

Pour cette opération de masquage, également dite de marouflage, on utilise habituellement du papier conditionné en un rouleau ; pour chaque organe à protéger, l'opérateur découpe et/ou déchire manuellement une feuille de papier ; la largeur de cette feuille est celle du rouleau de papier choisi, et la longueur de la feuille est approximativement déterminée par l'opérateur en fonction des dimensions de l'organe à protéger ; cette feuille présente donc deux premiers bords rectilignes parallèles, et deux deuxièmes bords dont la forme et l'orientation résultent de la technique de coupe utilisée ; en aucun cas la forme de la feuille ainsi formée ne correspond à celle de l'organe à protéger; l'opérateur peut ensuite déchirer et/ou froisser la feuille afin d'adapter grossièrement son contour à celui de l'organe à protéger ; ces opérations sont longues et délicates, et il n'en résulte jamais une feuille de forme parfaitement adaptée à celle de la pièce à protéger.For this masking operation, also called masking, usually used paper packaged in a roll; for each organ to be protected, the operator manually cuts and / or tears a sheet of paper; the width of this sheet is that of the chosen paper roll, and the length of the sheet is approximately determined by the operator according to the dimensions of the organ to be protected; this sheet thus has two first parallel straight edges, and two second edges whose shape and orientation result from the cutting technique used; in no case does the shape of the leaf thus formed correspond to that of the organ to be protected; the operator can then tear and / or crease the sheet so as to roughly adapt its contour to that of the organ to be protected; these operations are long and delicate, and never results in a form sheet perfectly adapted to that of the part to be protected.

Dans le domaine technique du bâtiment, il a été exposé, dans le brevet US-A- 3,752,304, l'idée consistant à utiliser des masques triangulaires pour recouvrir, avec recouvrement de deux masques adjacents, la surface rectangulaire vitrée d'une fenêtre ; deux masques identiques sont groupés pour former un rectangle ; les masques forment un rouleau muni de perforations transversales pour la réparation manuelle de feuilles rectangulaires; ce document ne donne aucune indication sur le matériau en feuille utilisable.In the technical field of building, it has been disclosed in US-A-3,752,304 the idea of using triangular masks to cover, with overlap of two adjacent masks, the rectangular glass surface of a window; two identical masks are grouped together to form a rectangle; the masks form a roll with transverse perforations for repair manual rectangular sheets; this document gives no indication of the usable sheet material.

Dans le domaine de la construction automobile, il est connu d'utiliser des masques de forme adaptée à celle d'une partie d'un véhicule pour protéger cette partie pendant une opération de peinture d'une autre partie du véhicule.In the field of automotive construction, it is known to use masks of a shape adapted to that of a part of a vehicle to protect this part during a painting operation of another part of the vehicle.

Le brevet US-A-4,420,520 décrit un masque de protection d'une partie vitrée ou bombée d'un véhicule, qui est réalisé dans un matériau en feuille, son contour étant en partie curviligne.US-A-4,420,520 discloses a protective mask of a glazed or convex portion of a vehicle, which is made of a sheet material, its contour being partly curvilinear.

Le brevet US 2,371,859 décrit un dispositif de masquage flexible qui est constitué d'une bande de caoutchouc et d'une couverture flexible en tissu qui est étalée sur la partie de carrosserie à protéger, en étant fixée et suspendue à la bande de caoutchouc ; cette bande est suffisamment flexible pour être appliquée à des surfaces présentant des coins et des contours irréguliers ; elle comporte une série de cavités formant des ventouses pour solidariser par succion la bande à la carrosserie, de sorte qu'aucun adhésif n'est nécessaire. Bien que ce dispositif présente des avantages, il n'est pas adapté pour permettre à moindre coût, de masquer rapidement et avec précision une partie vitrée d'un véhicule automobile.US Pat. No. 2,371,859 discloses a flexible masking device which consists of a rubber band and a flexible fabric cover which is spread over the body part to be protected, being fixed and suspended to the rubber band; this band is flexible enough to be applied to surfaces with irregular corners and contours; it comprises a series of cavities forming suction cups for securing the band to the body by suction, so that no adhesive is necessary. Although this device has advantages, it is not adapted to allow cheaply, to quickly and accurately hide a glazed portion of a motor vehicle.

Le document EP 334 360 décrit des structures feuilletées de masquage d'une partie de la face inférieure d'un véhicule comprenant une couche de mousse de matière plastique, une couche d'adhésif revêtant une face de la couche de mousse, et une feuille de protection décollable qui recouvre la couche adhésive ; des lignes de découpe discontinues constituées par des rainures ou des perforations sont prévues pour permettre de découper manuellement une partie de cette structure pour former un masque constitué d'un ou plusieurs masque(s) élémentaire(s) délimité(s) par ces lignes. On comprend qu'un tel système permet d'obtenir un masque présentant une forme très approximativement adaptée à la forme d'une partie de véhicule à protéger ; une telle structure ne s'adapte en fait parfaitement qu'à une partie de véhicule dont la forme épouse celle d'un masque élémentaire ou de plusieurs masques élémentaires juxtaposés ; une telle structure ne permet donc pas d'épouser précisément le contour d'une partie vitrée d'un véhicule.EP 334 360 discloses laminating structures for masking a portion of the underside of a vehicle comprising a layer of plastic foam, an adhesive layer coating one side of the foam layer, and a sheet of peel-off protection covering the adhesive layer; discontinuous cutting lines formed by grooves or perforations are provided to allow to manually cut a portion of this structure to form a mask consisting of one or more elementary mask (s) delimited (s) by these lines. It is understood that such a system makes it possible to obtain a mask having a shape that is very much adapted to the shape of a part of the vehicle to be protected; such a structure does in fact fit perfectly to a vehicle part whose shape matches that of an elementary mask or several juxtaposed elementary masks; such a structure does not allow to marry precisely the outline of a glazed portion of a vehicle.

L'invention a pour objet de proposer des masques de marouflage, leur procédé de fabrication et leur utilisation, qui soient améliorés et qui remédient, en partie au moins, aux inconvénients des procédés et dispositifs connus de marouflage.The invention aims to provide masking masks, their manufacturing process and their use, which are improved and which remedy, at least in part, the disadvantages of the known methods and devices of marouflage.

La présente invention a pour objet de proposer des masques de protection de parties vitrées de véhicules à moteur, en particulier de véhicules de transport, routier, aérien ou ferroviaire qui soient adaptés à la protection, à l'unité et à la demande, d'une quelconque partie vitrée d'un véhicule quelconque.The present invention aims to provide masks for protecting glazed parts of motor vehicles, in particular vehicles for transport, road, overhead or rail that are suitable for the protection, unit and demand, of any glazed part of any vehicle.

Selon un premier aspect, l'invention définie par les caractéristiques de la revendication 1 consiste à proposer un masque de protection d'une partie vitrée et/ou bombée d'un véhicule, qui est réalisé dans un matériau en feuille, et dont le contour est curviligne, en partie au moins et généralement en totalité, notamment en forme de polygone curviligne, de sorte que le contour du masque peut correspondre précisément, après déformation du masque en le plaquant contre ladite partie de véhicule, au contour de cette partie.According to a first aspect, the invention defined by the features of claim 1 is to provide a protective mask of a glazed portion and / or a convex portion of a vehicle, which is made of a sheet material, and whose contour is curvilinear, at least in part and generally entirely, in particular in the form of a curvilinear polygon, so that the contour of the mask may correspond precisely, after deformation of the mask by pressing against said vehicle part, to the contour of this part.

Afin de faciliter cette déformation au cours de laquelle le masque passe d'une configuration sensiblement plane à une configuration à trois dimensions (gauche) généralement complexe, ledit matériau en feuille constituant le masque est mince et léger ; l'épaisseur (repère 119 figure 14) de ce matériau est inférieure à 200 microns, en particulier située dans une plage allant de 20 à 80 microns; la masse surfacique de ce matériau est inférieure à 200 g/m2, en particulier située dans une plage allant de 20 à 80 g/m2, de préférence encore de 30 à 60 g/m2, en particulier voisine de 40 à 45 g/m2.In order to facilitate this deformation during which the mask changes from a substantially planar configuration to a generally complex three-dimensional configuration (left), said sheet material constituting the mask is thin and light; the thickness (reference 119 figure 14) of this material is less than 200 microns, in particular in a range of 20 to 80 microns; the weight per unit area of this material is less than 200 g / m 2 , in particular ranging from 20 to 80 g / m 2 , more preferably from 30 to 60 g / m 2 , in particular around 40 to 45 g / m 2 , g / m 2 .

De préférence, ledit matériau est monocouche et dénué d'adhésif.Preferably, said material is monolayer and devoid of adhesive.

Afin d'éviter que le masque ne se déforme ou ne se détériore lorsqu'il est en contact avec des substances aqueuses ou huileuses, on utilise un matériau présentant, sur ses deux faces, une résistance élevée à la pénétration de ces substances ; à cet effet, selon un mode préféré de réalisation, on choisit un papier simili-sulfurisé (ingraissable) sur ses deux faces, ou un papier kraft couché deux faces en polyéthylène.In order to prevent the mask from deforming or deteriorating when in contact with aqueous or oily substances, use is made of a material having on both sides a high resistance to penetration of these substances; for this purpose, according to a preferred embodiment, one chooses a paper imitation greaseproof (greaseproof) on both sides, or a kraft paper coated on both sides polyethylene.

Alternativement, le masque peut être réalisé en une matière plastique résistant aux solvants utilisés pour la peinture du véhicule, par thermoformage par exemple.Alternatively, the mask may be made of a plastics material resistant to solvents used for painting the vehicle, for example by thermoforming.

Afin de faciliter la manipulation d'un masque par l'opérateur, et de faciliter également le conditionnement, le transport et le stockage d'une pluralité de masques, le masque est prolongé (bordé), le long d'un de ses côtés curvilignes, par une bande (ou lisière) dudit matériau en feuille dont le contour présente de préférence une portion rectiligne.In order to facilitate the manipulation of a mask by the operator, and also to facilitate the packaging, transportation and storage of a plurality of masks, the mask is extended (bordered) along one of its curvilinear sides. , by a strip (or selvedge) of said sheet material whose contour preferably has a straight portion.

Cette bande permet de manipuler le masque dont elle est solidaire, sans contact avec le masque et donc sans risque de le détériorer.This band makes it possible to manipulate the mask of which it is integral, without contact with the mask and thus without risk of deteriorating it.

Par ailleurs, une telle bande facilite la solidarisation mutuelle de plusieurs masques, par solidarisation des bandes respectivement associées à chacun des masques ; à cet effet, on peut empiler plusieurs masques - et leurs bandes associées - de façon à ce que les bandes se recouvrent en tout ou partie, puis solidariser les bandes entre elles, par agrafage ou par collage; en outre ou alternativement, les bandes peuvent être percées d'un ou plusieurs orifices séparés d'une distance prédéterminée, et dont le diamètre permet le passage d'une tige faisant partie d'un support de masques ; une pluralité de masques peuvent ainsi être stockés suspendus à un tel support par l'intermédiaire de leur bande respective.Furthermore, such a band facilitates the mutual joining of several masks, by joining the strips respectively associated with each of the masks; for this purpose, one can stack several masks - and their associated strips - so that the bands overlap in all or part, then secure the strips together, by stapling or gluing; in addition or alternatively, the strips can be pierced with one or more orifices separated by a predetermined distance, and whose diameter allows the passage of a rod forming part of a mask holder; a plurality of masks can thus be stored suspended from such a support via their respective band.

Alternativement, les masques peuvent être stockés à plat dans un meuble présentant une pluralité de compartiments qui sont superposés les uns aux autres.Alternatively, the masks can be stored flat in a cabinet having a plurality of compartments that are superimposed on each other.

Dans ce cas notamment, la portion rectiligne du contour de la bande favorise un rangement compact et ordonné de plusieurs masques empilés, cette portion servant de butée lors de l'introduction des masques dans un compartiment du meuble ; de la même façon, cette portion rectiligne permet de réaliser facilement un empilement ordonné et harmonieux de plusieurs masques de formes différentes; ceci facilite le conditionnement dans un sachet souple (en matière plastique par exemple) de plusieurs masques.In this case in particular, the rectilinear portion of the contour of the strip promotes a compact and orderly storage of several stacked masks, this portion serving as a stop when the masks are introduced into a compartment of the piece of furniture; in the same way, this rectilinear portion makes it easy to produce an orderly and harmonious stack of several masks of different shapes; this facilitates the packaging in a flexible bag (plastic for example) of several masks.

Selon l'invention, la ligne courbe séparant un masque de sa bande associée est affaiblie par la présence de perforations ou de découpes de sorte que la désolidarisation d'un masque par rapport à la bande le prolongeant est facilitée.According to the invention, the curved line separating a mask from its associated band is weakened by the presence of perforations or cuts so that the separation of a mask with respect to the band extending it is facilitated.

Afin d'éviter de détériorer un masque lors de son transport, son stockage ou sa manipulation, celui-ci peut être plié en deux selon une ligne de pliage sensiblement médiane, ou bien peut être plié en accordéon selon plusieurs lignes de pliage parallèles entre elles et sensiblement orthogonales à la direction de plus grande dimension d'un masque ; ceci facilite en outre le conditionnement et le stockage de masques de grandes dimensions, comme en particulier les masques de protection d'un pare-brise ou d'une lunette arrière d'un véhicule.In order to avoid damaging a mask during its transport, storage or handling, it can be folded in half along a substantially median fold line, or it can be folded into an accordion according to several parallel fold lines between them. and substantially orthogonal to the larger dimension of a mask; this also facilitates the packaging and storage of masks of large dimensions, such as in particular the protective masks of a windshield or a rear window of a vehicle.

L'invention a notamment pour résultat un colis comportant une pluralité de masques à usagé unique, qui sont de préférence chacun prolongés par au moins une portion prolongatrice - telle qu'une bande - du matériau en feuille constituant le masque, et comportant des moyens de réunion pour réunir ensemble lesdits masques, ladite pluralité de masques permettant d'occulter plusieurs parties vitrées distinctes d'un véhicule ou d'une pluralité de véhicules identiques.The invention notably results in a package comprising a plurality of single-use masks, which are preferably each extended by at least one extension portion - such as a strip - of the sheet material constituting the mask, and comprising means for meeting to gather together said masks, said plurality of masks for concealing a plurality of separate glazed portions of a vehicle or a plurality of identical vehicles.

Ainsi, pour pouvoir protéger les parties vitrées d'une gamme déterminée de modèles de véhicules, il convient d'utiliser autant de colis différents qu'il y a de modèles différents dans ladite gamme.Thus, to be able to protect the glass parts of a given range of vehicle models, it is appropriate to use as many different packages as there are different models in said range.

Lesdits moyens de réunion peuvent comporter des agrafes ou de la colle solidarisant lesdits masques par leurs dites portions prolongatrices, et/ou un sachet souple enveloppant lesdits masques et leurs portions prolongatrices associées ; alternativement, les masques peuvent être reliés par leurs portions (ou bandes) prolongatrices associées de façon à former une bande continue comportant une pluralité de masques, cette bande étant enroulée pour former un rouleau ou bien pliée en zig-zag pour former une pile.Said meeting means may comprise staples or glue solidarisant said masks by their said extension portions, and / or a flexible bag enveloping said masks and their associated extension portions; alternatively, the masks may be joined by their associated extension portions (or bands) to form a continuous band having a plurality of masks, which band is rolled to form a roll or zig-zag folded to form a stack.

L'invention a notamment pour avantage de permettre, dans un atelier de réparation de carrosserie, de disposer avec un encombrement réduit, d'une grande quantité de masques de formes différentes permettant de masquer rapidement et avec précision, une ou plusieurs parties vitrées bombées d'un modèle quelconque de véhicule, à l'unité et à la demande.The invention has the particular advantage of allowing, in a body repair shop, to have with a small footprint, a large amount of masks of different shapes to hide quickly and accurately, one or more curved glass parts d any model of vehicle, individually and on demand.

La présente invention propose, selon un autre aspect, une bande de papier, qui est de préférence enroulée sur un mandrin tubulaire pour former un rouleau, dans laquelle sont découpés, en partie, une pluralité de masques de forme identique adaptée à la forme d'une partie vitrée d'un véhicule déterminé, et qui comporte une pluralité de premières portions de liaison affaiblies (de moindre résistance) s'étendant entre (et/ou séparant) deux masques adjacents de ladite bande, permettant de faciliter la désolidarisation des masques et d'éviter des déchirures inopportunes de la bande.The present invention provides, in another aspect, a paper web, which is preferably wound on a tubular mandrel to form a roll, in which a plurality of identically shaped masks adapted to the a glass part of a determined vehicle, and which comprises a plurality of weakened weakening first connection portions extending between (and / or separating) two adjacent masks of said strip, making it easier to separate the masks and to avoid untimely rips in the tape.

Alternativement, la bande de papier peut être pliée en zig-zag à la manière de papier « listing » (listage).Alternatively, the paper strip can be folded into a zig-zag in the manner of a "listing" paper.

Au sens de la présente demande, le terme « papier » désigne, outre le papier, les matériaux non métalliques en feuille, en particulier les matières plastiques et les matériaux stratifiés.For the purposes of the present application, the term "paper" designates, in addition to paper, non-metallic sheet materials, in particular plastics and laminated materials.

Afin d'augmenter la résistance mécanique de la bande de papier, celle-ci peut comporter au moins une lisière latérale détachable qui s'étend en continu le long d'un de ses bords, et qui est séparée desdits masques par une deuxième portion affaiblie (de moindre résistance) de façon à faciliter sa désolidarisation desdits masques.In order to increase the mechanical strength of the paper web, it may comprise at least one detachable lateral edge which extends continuously along one of its edges, and which is separated from said masks by a second weakened portion (of least resistance) so as to facilitate its separation of said masks.

Selon un mode préféré de réalisation, la bande de papier comporte deux lisières latérales détachables continues qui s'étendent respectivement le long de chacun de ses bords longitudinaux.According to a preferred embodiment, the paper web has two continuous detachable lateral edges which extend respectively along each of its longitudinal edges.

Selon une alternative préférée de réalisation, l'une ou l'autre ou les deux lisières latérales détachables sont discontinues ; dans ce cas, le contour de chacun des masques comporte une partie affleurante le long d'au moins un des bords de la bande de papier, c'est à dire s'étend tangentiellement à celui-ci, ce qui contribue à diminuer les chutes inutiles de papier.According to a preferred alternative embodiment, one or the other or both detachable lateral edges are discontinuous; in this case, the contour of each of the masks comprises a portion flush along at least one edge of the paper web, ie extends tangentially thereto, which contributes to reducing the falls unnecessary paper.

Afin de limiter ces chutes de papier, lesdites premières portions affaiblies de liaison entre deux masques ont une largeur très petite comparée aux dimensions du masque : le rapport de cette largeur à la dimension moyenne d'un masque est de préférence inférieure ou égale à 10-1 ; ce rapport peut aller jusqu'à 10-2, 10-3 ou 10-4, et peut même dans certaines applications, être de valeur nulle, lorsque les contours de deux masques adjacents sont disposés tangentiellement l'un à l'autre.In order to limit these paper falls, said first weakened connection portions between two masks have a very small width compared to the mask dimensions: the ratio of this width to the average dimension of a mask is preferably less than or equal to 10 - 1 ; this ratio can be up to 10 -2 , 10 -3 or 10 -4 , and can even in some applications be zero, when the contours of two adjacent masks are arranged tangentially to one another.

De préférence, le rapport de la largeur de chacune desdites lisières latérales à ladite dimension moyenne du masque est situé dans la, même plage de valeurs que celles indiquées ci-dessus concernant lesdites portions de liaison ; par dimension moyenne d'un masque, on entend son diamètre équivalent (D) qui est calculé par la formule D = √ ( 4 S / π )

Figure imgb0001
, où S est la surface du masque.Preferably, the ratio of the width of each of said lateral edges to said average mask dimension is in the same range of values as those indicated above for said connecting portions; by mean dimension of a mask, we mean its equivalent diameter (D) which is calculated by the formula D = √ ( 4 S / π )
Figure imgb0001
 , where S is the surface of the mask.

Afin de limiter les chutes et/ou pour limiter la largeur desdites premières portions affaiblies de liaison, lesdits masques peuvent être disposés tête-bêche deux à deux.In order to limit the falls and / or to limit the width of said first weakened connecting portions, said masks can be arranged head to tail in pairs.

Dans un mode préféré de réalisation, la bande de papier comporte une seule pluralité de masques identiques ; selon une variante préférée, la bande peut comporter au moins deux pluralités de masques : une première pluralité de premiers masques identiques (par exemple de forme adaptée à celle d'une vitre latérale avant d'un véhicule déterminé), et une deuxième pluralité de deuxièmes masques identiques (par exemple de forme adaptée à celle d'une vitre latérale arrière dudit véhicule), qui sont d'une forme différente de celle desdits premiers masques.In a preferred embodiment, the paper web has a single plurality of identical masks; according to a preferred variant, the band may comprise at least two pluralities of masks: a first plurality of identical first masks (for example of a shape adapted to that of a front side window of a given vehicle), and a second plurality of second identical masks (for example of a shape adapted to that of a rear side window of said vehicle), which are of a shape different from that of said first masks.

Dans ce cas, lesdits premiers masques sont disposés alternativement avec lesdits deuxièmes masques, le long de la bande de papier.In this case, said first masks are alternately arranged with said second masks, along the paper web.

L'affaiblissement des portions de liaison et/ou des lisières peut être obtenu par une perforation ou une coupe discontinue de la bande de papier, le long d'une ligne d'affaiblissement qui peut s'étendre le long d'une portion au moins du contour des masques, et qui peut être rectiligne ou curviligne, transversale, longitudinale, ou oblique. ,The weakening of the connecting portions and / or selvedges can be achieved by perforation or discontinuous cutting of the paper web, along a weakening line which can extend along at least a portion contour of the masks, and which may be rectilinear or curvilinear, transverse, longitudinal, or oblique. ,

Afin de limiter le nombre de bandes de papier nécessaires pour masquer toutes les parties vitrées d'un véhicule déterminé, on peut imbriquer sur une bande de papier 2, 3, 4 (ou plus), masques de forme différente.In order to limit the number of paper strips necessary to hide all the glass parts of a given vehicle, masks of different shapes can be embedded on a strip of paper 2, 3, 4 (or more).

Dans le même but, on peut également utiliser un papier ayant des propriétés absorbantes de produits liquides ou pâteux sensiblement identiques pour ses deux faces, de sorte qu'un masque tel que celui d'une vitre avant gauche pourra indifféremment être utilisé pour masquer cette vitre ou pour masquer la vitre « symétrique », c'est-à-dire la vitre avant droit du même véhicule.For the same purpose, it is also possible to use a paper having absorbent properties of liquid or pasty products that are substantially identical for its two faces, so that a mask such as that of a front left window can indifferently be used to mask this window. or to hide the "symmetrical" glass, that is to say the right front window of the same vehicle.

On peut également prévoir d'inclure un ou plusieurs masques de petites dimensions, tels que les masques de phares, à l'intérieur d'un masque de grande dimension, tel que le masque du pare-brise (du même véhicule).It is also possible to include one or more masks of small dimensions, such as headlight masks, inside a large mask, such as the mask of the windshield (of the same vehicle).

On peut alors séparer les deux masques le long d'une zone affaiblie s'étendant le long du contour du masque de petites dimensions ; après séparation de ces deux masques, l'évidement créé à l'intérieur du masque de grande dimension peut être utilisé pour solidariser le masque à la partie vitrée à l'aide d'une bande adhésive s'étendant en partie dans l'évidement ; cet évidement peut (en tant que de besoin) facilement être occulté par une autre feuille de papier grossièrement coupée.The two masks can then be separated along a weakened zone extending along the contour of the small mask; after separation of these two masks, the recess created inside the large mask can be used to secure the mask to the glass part with an adhesive tape extending partially into the recess; this recess can (as needed) be easily concealed by another sheet of roughly cut paper.

Afin de faciliter la séparation des masques prédécoupés dans la bande de papier et d'optimiser le nombre de masques par rouleau, on utilise de préférence un papier dont le grammage est inférieur ou égal à 200 g/m2, en particulier inférieur ou égal à 100 g/m2, par exemple de l'ordre de 20 à 60 g/m2.In order to facilitate the separation of the pre-cut masks in the paper web and to optimize the number of masks per roll, it is preferable to use a paper whose grammage is less than or equal to 200 g / m 2 , in particular less than or equal to 100 g / m 2 , for example of the order of 20 to 60 g / m 2 .

Afin de faciliter la maniabilité des rouleaux, on utilisera de préférence une bande de papier de largeur inférieure ou égale à 1 m, de longueur inférieure ou égale à 200 m, et de masse inférieure ou égale à 20 kg ; à cet effet également, on limitera le diamètre des rouleaux à 15 ou 20 cm environ au maximum.In order to facilitate the handling of the rollers, it will be preferable to use a paper strip of width less than or equal to 1 m, of length less than or equal to 200 m, and of mass less than or equal to 20 kg; for this purpose also, it will limit the diameter of the rolls to 15 or 20 cm at most.

Selon un autre aspect, l'invention consiste à proposer un dispositif de stockage et de distribution de masques prédécoupés aux formes des parties vitrées de plusieurs véhicules automobiles ; le dispositif comporte une pluralité de barres parallèles qui sont (chacune) aptes à recevoir un, ou de préférence plusieurs, routeau(x) de papier; chaque rouleau comporte au moins une pluralité de masques prédécoupés et formant une bande ; la bande peut être déroulée de la longueur nécessaire pour en extraire un masque, par rotation du rouleau et/ou de la barre supportant le rouleau ; cette rotation peut résulter d'un effort manuel de traction exercée sur l'extrémité libre de la bande de papier.According to another aspect, the invention consists in proposing a device for storing and dispensing pre-cut masks for the shapes of glazed parts of several motor vehicles; the device comprises a plurality of parallel bars which are (each) adapted to receive one, or preferably several, paper (s); each roll has at least a plurality of pre-cut masks forming a band; the strip may be unwound of the length necessary to extract a mask, by rotation of the roller and / or the bar supporting the roller; this rotation may result from a manual pulling force exerted on the free end of the paper web.

Selon un mode préféré de réalisation, le dispositif comporte une pluralité de barres (ou arbres) support de rouleaux, qui sont superposées et sont supportées par un châssis commun auxdites barres ; le pas d'espacement des barres est de préférence inférieur ou égal à 30 cm.According to a preferred embodiment, the device comprises a plurality of roll support bars (or shafts), which are superimposed and are supported by a frame common to said bars; the spacing pitch of the bars is preferably less than or equal to 30 cm.

L'invention procure un dispositif compact, simple à fabriquer et à utiliser ; afin d'améliorer encore sa compacité, il peut comporter deux séries de barres superposées qui s'étendent dans deux plans sensiblement verticaux.The invention provides a compact device, simple to manufacture and use; in order to further improve its compactness, it may comprise two series of superposed bars which extend in two substantially vertical planes.

De préférence, les barres sont de longueur identique, et leur longueur leur permet de recevoir plusieurs rouleaux côte à côte ; on peut ainsi regrouper sur une barre (ou sur deux barres adjacentes) les rouleaux -comportant tous les masques d'un modèle de véhicule déterminé, afin de faciliter le repérage des rouleaux sur le râtelier de stockage et de distribution.Preferably, the bars are of identical length, and their length allows them to receive several rolls side by side; it is thus possible to group together on one bar (or on two adjacent bars) the rollers -comportant all the masks of a given vehicle model, in order to facilitate the identification of the rollers on the storage and distribution rack.

Par référence aux figures 1 à 5 et 8 en particulier, la bande 1 en papier dans laquelle sont prédécoupés les masques de marouflage, est enroulée sur un mandrin tubulaire d'axe 2 pour former un rouleau 3.With reference to FIGS. 1 to 5 and 8 in particular, the paper strip 1 in which the masking masks are pre-cut is wound on a tubular mandrel of axis 2 to form a roll 3.

La partie déroulée de la bande 1 s'étend selon un axe 4 ; les bords latéraux 5 et 6 de la bande sont parallèles à l'axe 4 ; la largeur 7 de la bande 1 figure 1 est adaptée à la largeur 8 des masques 9 identiques qui sont prédécoupés dans cette bande ; chaque masque 9 peut être calqué sur la forme d'un pare-brise d'un véhicule automobile déterminé, et les masques 10, 11, 12, 13 et 14 prédécoupés dans les bandes des figures 2 à 5 peuvent respectivement correspondre à la forme des vitres avant (masques 10a, 10b), des vitres arrières (masques 11a, 11b, 12a, 12b, 12c, 12d), du rétroviseur (13a, 13b) et des capots de phare (14) dudit véhicule déterminé.The unwound portion of the strip 1 extends along an axis 4; the lateral edges 5 and 6 of the strip are parallel to the axis 4; the width 7 of the band 1, FIG. 1, is adapted to the width 8 of the identical masks 9 which are pre-cut in this band; each mask 9 can be modeled on the shape of a windshield of a given motor vehicle, and the masks 10, 11, 12, 13 and 14 precut in the bands of Figures 2 to 5 can respectively correspond to the shape of front windows (masks 10a, 10b), rear windows (masks 11a, 11b, 12a, 12b, 12c, 12d), the mirror (13a, 13b) and headlamps (14) of said determined vehicle.

Ainsi, pour un type ou modèle de véhicule peuvent être prévus de quatre à huit rouleaux, en particulier les six rouleaux 31 à 36 de la figure 6 ; les six aubes rouleaux 37 à 312 contiennent les masques de forme adaptée aux parties vitrées d'un deuxième type ou modèle de véhicule; les différents rouleaux adaptés à un véhicule déterminé sont regroupés côte à côte sur une ou plusieurs barres adjacentes 15 du dispositif 16 de distribution de masques.Thus, for a type or model vehicle can be provided from four to eight rollers, particularly rollers six March 1 to March 6 of Figure 6; the six blades 31 to 31 12 contain the shape masks adapted to the glazed parts of a second type or model of vehicle; the different rollers adapted to a given vehicle are grouped side by side on one or more adjacent bars 15 of the mask dispensing device 16.

Le distributeur 16 illustré figure 7 comporte huit premières barres 151 parallèles d'axe horizontal, et superposées, qui s'étendent en face avant du distributeur et comporte huit deuxièmes barres 152 horizontales superposées qui s'étendent en face arrière du distributeur ; les barres 15, 151, 152 sont fixées sur un châssis 160 et disposées régulièrement espacées le long d'un axe vertical.The dispenser 16 illustrated in FIG. 7 comprises eight first parallel bars 1 of horizontal axis, and superposed, which extend on the front face of the dispenser and comprises eight second superposed horizontal bars 2 which extend on the rear face of the dispenser; the bars 15, 15 1 , 15 2 are fixed to a frame 160 and regularly spaced apart along a vertical axis.

Le châssis repose au sol par des pieds 17 et reçoit des panneaux latéraux 18, 19 et supérieur 20 qui abritent les rouleaux et reçoivent des signes indiquant, pour chaque barre et/ou chaque rouleau, le véhicule et la partie vitrée correspondante.The frame rests on the ground by feet 17 and receives side panels 18, 19 and upper 20 which house the rollers and receive signs indicating, for each bar and / or each roller, the vehicle and the corresponding glazed part.

Les masques 9, 10, 11 et 13 sont en forme de quadrilatères curvilignes tandis que les masques 12a à 12d, qui sont de forme identique correspondant à celle d'une vitre de Custode (partie arrière d'une vitre arrière) d'un véhicule, sont en forme de triangle curviligne, et les masques de phare 14 sont en forme de languette.The masks 9, 10, 11 and 13 are in the form of curvilinear quadrilaterals whereas the masks 12a to 12d, which are of identical shape corresponding to that of a Custode glass (rear part of a rear window) of a vehicle , are in the form of a curvilinear triangle, and the headlight masks 14 are tab-shaped.

Le contour du masque 9 est défini par quatre tronçons rectilignes 21 à 24 parallèles deux à deux et raccordés par quatre tronçons curvilignes en forme d'arc de cercle; des perforations et/ou des segments coupés sont disposés de façon discontinue le long de ces tronçons et forment un contour affaibli autour du masque 9, facilitant sa séparation par rapport aux portions de la bande de papier qui entourent le masque ; ces portions consistent en deux lisières latérales 25 et 26 de faible largeur 53, et en deux portions 27 et 28 de liaison, de largeur également faible.The outline of the mask 9 is defined by four rectilinear sections 21 to 24 parallel in pairs and connected by four curvilinear sections in the form of a circular arc; perforations and / or cut segments are arranged discontinuously along these sections and form a weakened contour around the mask 9, facilitating its separation from the portions of the paper web that surround the mask ; these portions consist of two lateral edges 25 and 26 of small width 53, and two portions 27 and 28 of connection, of equally small width.

Les lisières 25, 26 s'étendent entre le bord 5 de la bande 1 et le tronçon rectiligne 21 d'une part, et entre le bord 6 de la bande 1 et le tronçon rectiligne 23 d'autre part.The selvedges 25, 26 extend between the edge 5 of the strip 1 and the rectilinear section 21 on the one hand, and between the edge 6 of the strip 1 and the rectilinear section 23 on the other hand.

Chaque portion 27, 28 de liaison s'étend entre deux masques 9 consécutivement prévus sur la bande 1, et comporte un tronçon affaibli 29 perforé et/ou coupé de façon discontinue, qui s'étend d'un bord 5 à l'autre 6 de la bande 1, le long d'une droite perpendiculaire à ces bords.Each portion 27, 28 of connection extends between two masks 9 consecutively provided on the strip 1, and comprises a weakened section 29 perforated and / or cut discontinuously, which extends from one edge 5 to the other 6 of the band 1, along a line perpendicular to these edges.

De façon similaire, les bandes illustrées figures 2 à 5 comportent des portions transversales de liaison entre deux masques adjacents qui sont affaiblies par la présence de lignes 30 à 33 perforées et/ou prédécoupées qui s'étendent perpendiculairement aux bords 5, 6.Similarly, the strips illustrated in FIGS. 2 to 5 comprise transverse connection portions between two adjacent masks which are weakened by the presence of perforated and / or pre-cut lines 30 to 33 which extend perpendicularly to the edges 5, 6.

En outre, la bande illustrée figure 2 comporte une portion oblique de liaison entre deux masques 10a, 10b qui s'étend selon (et englobe) une ligne oblique (par rapport aux bords 5, 6) perforée 34 ; de façon similaire, une bande de liaison oblique incluant une ligne 35 oblique de prédécoupage sépare deux masques 14 adjacents disposés tête-bêche (figure 5).In addition, the band illustrated in Figure 2 comprises an oblique connecting portion between two masks 10a, 10b which extends along (and includes) an oblique line (with respect to the edges 5, 6) perforated 34; similarly, an oblique connecting strip including an oblique precut line separates two adjacent masks 14 arranged upside down (Figure 5).

Dans le mode de réalisation illustré figures 3 et 8, la bande 1 comporte une pluralité de masques 11a, 11b de forme identique, qui sont disposés alternativement avec une pluralité de masques 12a, 12b, 12c et 12d de forme identique, disposés symétriquement par rapport à l'axe 4, et qui sont imbriqués par deux entre deux masques 11a, 11b, la forme des masques 12a à 12d étant différente de celle des masques 11a, 11b.In the embodiment illustrated in FIGS. 3 and 8, the strip 1 comprises a plurality of masks 11a, 11b of identical shape, which are alternately arranged with a plurality of masks 12a, 12b, 12c and 12d of identical shape, arranged symmetrically with respect to each other. at the axis 4, and which are interleaved by two between two masks 11a, 11b, the shape of the masks 12a to 12d being different from that of the masks 11a, 11b.

Dans ce mode de réalisation, la bande comporte des portions transversales 36 de liaison affaiblies par les lignes perforées 31, ainsi que des portions longitudinales 37 de liaison affaiblies par des lignes perforées longitudinales 38 parallèles à l'axe 4.In this embodiment, the strip has weakened cross-linking portions 36 by the perforated lines 31, as well as longitudinal connection portions 37 weakened by longitudinal perforated lines 38 parallel to the axis 4.

Dans le mode de réalisation illustré figure 9, la bande 1 de papier est uniquement constituée d'une pluralité de masques 50 de forme rectangulaire arrondie; deux masques adjacents sont solidaires par une partie prédécoupée rectiligne 51 de contour ; ainsi la bande est dénuée de lisières latérales, celles-ci étant séparées de la bande lors de sa fabrication ; dans cet exemple de réalisation, la largeur des portions transversales de liaison 51 entre deux masques adjacents, est nulle. La bande 1 est pliée selon les lignes 51 de prédécoupé qui s'étendent perpendiculairement aux bords 5, 6, de façon à former une pile 52 de masques 50.In the embodiment illustrated in FIG. 9, the strip 1 of paper consists solely of a plurality of masks 50 of rounded rectangular shape; two adjacent masks are secured by a rectilinear straight portion 51 contour; thus the band is devoid of lateral edges, these being separated from the band during its manufacture; in this exemplary embodiment, the width of the transverse connection portions 51 between two adjacent masks is zero. The band 1 is folded along the pre-cut lines 51 which extend perpendicularly to the edges 5, 6, so as to form a stack 52 of masks 50.

Les bandes peuvent en particulier être constituées de papier dont le grammage est voisin de 40 à 45 g/m2.The strips may in particular be made of paper whose grammage is close to 40 to 45 g / m 2 .

Par référence à la figure 10, le masque 100 dont la surface est hachurée, est délimité par un contour 101 curviligne de forme sensiblement ovoïde.With reference to FIG. 10, the mask 100 whose surface is hatched is delimited by a curvilinear contour 101 of substantially ovoid shape.

Une partie de ce contour forme une ligne 108 de démarcation séparant le masque 100 d'une bande prolongatrice 104 s'étendant le long de la ligne-courbe 108.Part of this contour forms a demarcation line 108 separating the mask 100 from an extension strip 104 extending along the curved line 108.

Une pluralité de découpes 109 sont formées dans la feuille formant le masque 100 et la bande 104, qui s'étendent selon la ligne 108 et provoquent un affaiblissement de la feuille selon cette ligne en vue de faciliter la séparation de la bande 104 et du masque 100 selon cette ligne 108.A plurality of cutouts 109 are formed in the sheet forming the mask 100 and the strip 104, which extend along the line 108 and cause a weakening of the sheet along this line to facilitate the separation of the strip 104 and the mask 100 according to this line 108.

La bande 104 est percée de deux orifices 107 au travers desquels peuvent s'étendrent deux tiges d'un support de masques (non représenté).The band 104 is pierced with two orifices 107 through which can extend two rods of a mask holder (not shown).

Outre la ligne courbe 108, trois segments rectilignes 106a, 106b, 106c, délimitent la bande 104 et facilitent la mise en butée du dispositif 110 de masquage contre une paroi (non représentée), par appui de la tranche de la feuille s'étendant le long de ces tronçons, et facilitent par conséquent la manipulation, le conditionnement, le stockage et la discrimination visuelle de plusieurs dispositifs empilés.In addition to the curved line 108, three rectilinear segments 106a, 106b, 106c, delimit the band 104 and facilitate the abutment of the masking device 110 against a wall (not shown), by supporting the edge of the sheet extending the along these sections, and thus facilitate the manipulation, packaging, storage and visual discrimination of several stacked devices.

Par référence à la figure 11, le masque 120 dont la surface est hachurée, est délimité par un contour 130 curviligne en forme de haricot.With reference to FIG. 11, the mask 120, the surface of which is hatched, is delimited by a curvilinear contour 130 in the form of a bean.

L'intégralité de ce contour forme une ligne de démarcation séparant le masque 120 d'un cadre prolongateur 105 qui s'étend entre le contour 130 (interne) et un contour externe rectangulaire formé de quatre segments rectilignes 106a, 106b, 106c, 106d.The entire contour forms a demarcation line separating the mask 120 from an extension frame 105 which extends between the contour 130 (inner) and a rectangular outer contour formed by four straight segments 106a, 106b, 106c, 106d.

Le contour 130 servant de ligne de démarcation est muni de perforations 109 régulièrement espacées.The outline 130 serving as demarcation line is provided with perforations 109 regularly spaced.

Le dispositif 110 de masquage se présente sous la forme d'une bande 2000 continue de papier s'étendant le long d'un axe 135, dont une portion est illustrée figure 11, qui comporte une pluralité de masques 120 identiques qui sont régulièrement espacés le long de cet axe, et autant de cadres 105 prolongeant les masques.The masking device 110 is in the form of a continuous strip 2000 of paper extending along an axis 135, a portion of which is illustrated in FIG. 11, which comprises a plurality of identical masks 120 which are regularly spaced on along this axis, and as many frames 105 extending the masks.

Chaque masque peut être plié selon un axe médian 136 lorsque la bande 2000 est pliée en accordéon selon les axes 136 et 137 ; les portions rectilignes 106a et 106c du contour du cadre 105, qui s'étendent selon les axes 137 orthogonaux à l'axe 135 et qui séparent deux cadres adjacents, sont de préférence affaiblies par des perforations ou découpes telles que celles repérées 109.Each mask may be folded along a median axis 136 when the strip 2000 is folded in accordion along the axes 136 and 137; the rectilinear portions 106a and 106c of the outline of the frame 105, which extend along the axes 137 orthogonal to the axis 135 and which separate two adjacent frames, are preferably weakened by perforations or cuts such as those marked 109.

Par référence à la figure 12, le colis 110 est constitué de trois masques 121, 122 et 123 empilés dont les contours respectifs 131, 132 et 133 sont en partie curvilignes.Referring to Figure 12, the package 110 consists of three masks 121, 122 and 123 stacked whose respective contours 131, 132 and 133 are partly curvilinear.

Chacun de ces masques est respectivement prolongé par une bande 104 dont un bord 106 est rectiligne et qui comporte deux orifices 107 ; pour faciliter le transport et le conditionnement, les bandes 104 sont réunies par des agrafes 111, et leurs portions rectilignes 106 de contour respectives sont superposées (alignées verticalement).Each of these masks is respectively extended by a band 104 whose edge 106 is rectilinear and which has two orifices 107; to facilitate transportation and packaging, the strips 104 are joined by staples 111, and their respective rectilinear portions 106 of outline are superimposed (vertically aligned).

Le cas échéant après extraction des agrafes 111, les masques et leurs bandes associées peuvent être stockées à plat dans un atelier de réparation automobile, dans les compartiments parallélépipédiques superposés 141, 142, 143 d'un meuble 144 de rangement de masques (figure 13), les portions rectilignes 106 de contour des bandes étant en butée contre une paroi latérale verticale 145 à 147 respective de chaque compartiment dont la forme et les dimensions sont respectivement adaptés à chacun des masques 121 à 123.If necessary after extraction of the staples 111, the masks and their associated strips can be stored flat in an automobile repair shop, in the superposed parallelepiped compartments 141, 142, 143 of a cabinet 144 for storing masks (FIG. 13). , the rectilinear portions 106 of contour strips being in abutment against a vertical side wall 145 to 147 respectively of each compartment whose shape and dimensions are respectively adapted to each of the masks 121 to 123.

De préférence, pour la fabrication de masques selon l'invention, on forme une pile d'une pluralité de feuilles dudit matériau, puis on coupe simultanément, de préférence par action d'un jet de liquide (en particulier d'eau) ou d'un faisceau laser, ladite pluralité de feuilles empilées de façon à obtenir une pluralité de masques identiques le cas échéant prolongés par lesdites bandes ou portions prolongatrices ; alternativement, la coupe le long du contour du masque peut être effectuée par oxycoupage, par poinçonnage ou plasma.Preferably, for the manufacture of masks according to the invention, a stack of a plurality of sheets of said material is formed and then cut simultaneously, preferably by the action of a jet of liquid (in particular water) or a laser beam, said plurality of sheets stacked so as to obtain a plurality of identical masks optionally extended by said strips or extension portions; alternatively, the cutting along the contour of the mask can be performed by oxycutting, punching or plasma.
