Ruban adhésif de masquage de pièces. 5 DOMAINE DE L'INVENTION  Masking adhesive tape. FIELD OF THE INVENTION

La présente invention concerne un ruban adhésif destiné à être utilisé par des peintres, chaudronniers, tôliers, carrossiers ou analogues effectuant de la peinture au pistolet ou similaire. ARRIERE PLAN DE L'INVENTION  The present invention relates to an adhesive tape for use by painters, boilermakers, sheet metal workers, body builders or the like performing spray painting or the like. BACKGROUND OF THE INVENTION

Dans le domaine de la carrosserie, il est bien connu que, avant de peindre une pièce, par exemple une portière d'automobile, on masque la ou les pièces adjacentes 15 telles que l'aile de l'automobile, et accessoirement certaines parties de la pièce, afin de les protéger contre les projections de peinture. Cette étape de masquage également appelée marouflage est généralement obtenue en recouvrant la ou les pièces à protéger d'une feuille de papier ou d'un film plastique maintenus en position par un ruban adhésif souple. 20 De cette manière, la pièce à peindre est partiellement ou totalement entourée par un ruban collé. La mise en place de ces feuilles de protection par de tels rubans adhésifs est particulièrement difficile et longue pour certaine pièce. Par ailleurs, après application de la peinture au pistolet ou par tout autre moyen 25 équivalent, la feuille de protection est arrachée et on constate fréquemment qu'une arête vive subsiste le long de la frontière séparant la zone peinte et la zone non peinte de la pièce. De plus, il est souvent nécessaire de boucher un joint entre deux pièces à peindre tel qu'entre une portière et une aile d'automobile par exemple. Les 30 carrossiers utilisent alors une bande en mousse compressible.  In the field of bodywork, it is well known that, before painting a part, for example an automobile door, it masks the adjacent room or parts 15 such as the wing of the car, and incidentally some parts of the car. the room, to protect them from splashing paint. This masking step, also known as marouflage, is generally obtained by covering the part or parts to be protected with a sheet of paper or a plastic film held in position by a flexible adhesive tape. In this way, the piece to be painted is partially or totally surrounded by a glued tape. The introduction of these protective sheets by such adhesive tapes is particularly difficult and long for certain parts. On the other hand, after application of the paint spray or by any other equivalent means, the protective sheet is torn off and it is frequently observed that a sharp edge remains along the border separating the painted zone and the unpainted zone from the room. In addition, it is often necessary to seal a seal between two parts to paint such as between a door and a car wing, for example. The coachbuilders then use a compressible foam tape.

Afin de préparer une automobile avant d'effectuer des travaux de peinture, le carrossier est ainsi obligé de manipuler plusieurs rubans, ce qui, outre une efficacité discutable, grève considérablement la durée des travaux et par conséquent son coût. Afin de remédier à ces inconvénients, on a déjà imaginé des rubans adhésifs adaptés aux travaux de carrosserie et aptes d'une part à assurer un joint entre deux pièces d'une automobile et d'autre part à permettre la fixation d'un film de protection sur les autres pièces de l'automobile. C'est le cas par exemple de la demande de brevet internationale WO 96/26789 qui décrit un procédé de masquage et un ruban pour la mise en oeuvre du procédé. i0 Le ruban adhésif est constitué d'un ruban souple muni le long d'un premier bord d'une première face d'une fine bande de colle et le long du bord opposé de la face opposée d'une seconde fine bande de colle. De la sorte, ce ruban peut être utilisé au niveau d'un interstice, par exemple entre un capot et une aile, la première fine bande de colle d'une première face du 15 ruban venant adhérer à une zone de l'une des pièces délimitant cet interstice, à l'intérieur de ce dernier, tandis que l'autre fine bande de colle vient adhérer à l'autre des pièces délimitant cet interstice, le ruban étant replié en forme de boucle. Ce type de ruban ne permet néanmoins pas d'assurer l'étanchéité entre toutes les pièces de carrosserie tout en assurant la protection d'une pièce de carrosserie 20 adjacente qui doit être protégée par un film protecteur. On connaît, par ailleurs, le brevet anglais GB 2 079 628 qui décrit un ruban adhésif particulièrement destiné aux travaux de carrosserie. Ce ruban adhésif comporte une bande souple de support et sur chacune de ses faces une bande de colle, lesdites bandes colles ne s'étendant pas l'une au regard de l'autre. 25 De la même manière que précédemment, ce type de ruban ne permet pas d'assurer l'étanchéité entre toutes les pièces de carrosserie tout en assurant la protection d'une pièce de carrosserie adjacente qui doit être protégée par un film protecteur.  In order to prepare an automobile before carrying out painting work, the bodybuilder is thus obliged to handle several ribbons, which, in addition to questionable efficiency, considerably strike the duration of the work and consequently its cost. In order to overcome these drawbacks, adhesive tapes adapted to bodywork work have already been devised and capable, on the one hand, of ensuring a seal between two parts of an automobile and, on the other hand, of allowing the attachment of a film of protection on other parts of the automobile. This is the case, for example, of the international patent application WO 96/26789 which describes a masking method and a tape for carrying out the method. The adhesive tape consists of a flexible tape provided along a first edge of a first face with a thin strip of glue and along the opposite edge of the opposite face of a second thin strip of glue. In this way, this tape can be used at a gap, for example between a hood and a wing, the first thin strip of glue of a first face of the tape coming to adhere to an area of one of the pieces delimiting this gap, inside the latter, while the other thin strip of adhesive is adhered to the other of the parts defining this gap, the tape being folded into a loop shape. This type of ribbon, however, does not provide sealing between all the body parts while providing protection for an adjacent bodywork part 20 which must be protected by a protective film. It is known, moreover, the British Patent GB 2,079,628 which describes an adhesive tape particularly intended for bodywork. This adhesive tape comprises a flexible support strip and on each of its faces a band of adhesive, said adhesive strips not extending one against the other. In the same manner as before, this type of ribbon does not make it possible to seal between all the bodywork parts while ensuring the protection of an adjacent bodywork part which must be protected by a protective film.

30 BREVE DESCRIPTION DE L'INVENTION L'un des buts de l'invention est donc de remédier à tous ces inconvénients en proposant un ruban adhésif de conception simple et peu onéreuse et particulièrement destiné à masquer rapidement et efficacement une ou plusieurs pièces de carrosserie ou similaire lors de travaux de peinture. A cet effet, et conformément à l'invention, il est proposé un ruban adhésif comprenant une bande de support souple munie sur une première face d'une première bande de colle longitudinale s'étendant depuis un premier bord de la bande support, ladite première bande de colle ne couvrant que partiellement la première face de la bande support, et sur la face opposée d'une seconde bande de colle longitudinale s'étendant depuis le bord opposé de ladite bande support, ladite seconde bande de colle ne couvrant que partiellement la face opposée de la bande support ; ledit ruban est remarquable en ce que la première bande de colle de la première face de la bande support présente une largeur I supérieure à largeur L de la bande support et de préférence une largeur I comprise entre 3 et 4 cinquièmes de la largeur L de la bande support. Selon une première variante d'exécution de l'invention, la seconde bande de colle longitudinale s'étend au droit de la zone non adhérente de la première face de la bande support et présente une largeur comprise entre 1 et 2 cinquièmes de la largeur L de la bande support. Selon une seconde variante d'exécution de l'invention, une partie de la première bande de colle de la première face de la bande support s'étend au droit d'une partie de la seconde bande de colle de la face opposée de ladite bande support pour former une zone de recouvrement de largeur Ir.  BRIEF DESCRIPTION OF THE INVENTION One of the aims of the invention is thus to overcome all these drawbacks by proposing an adhesive tape of simple and inexpensive design and particularly intended to quickly and effectively hide one or more body parts or similar during painting work. For this purpose, and in accordance with the invention, there is provided an adhesive tape comprising a flexible support strip provided on a first face with a first longitudinal adhesive strip extending from a first edge of the support strip, said first an adhesive strip covering only partially the first face of the support strip, and on the opposite side of a second longitudinal glue strip extending from the opposite edge of said support strip, said second glue strip only partially covering the opposite side of the support strip; said ribbon is remarkable in that the first adhesive strip of the first face of the support strip has a width I greater than width L of the support strip and preferably a width I of between 3 and 4 fifths of the width L of the support tape. According to a first variant embodiment of the invention, the second longitudinal adhesive strip extends to the right of the non-adherent zone of the first face of the support strip and has a width of between 1 and 2 fifths of the width L of the support tape. According to a second variant embodiment of the invention, a part of the first adhesive strip of the first face of the support strip extends in line with a portion of the second adhesive strip of the opposite face of said strip. support for forming an overlap area of width Ir.

Cette zone de recouvrement présente une largeur Ir comprise entre 2 et 4 cinquièmes de la largeur L de la bande support et de préférence une largeur Ir égale à 3 cinquièmes de la largeur L de la bande support. De manière avantageuse, la zone de recouvrement s'étend longitudinalement et est centrée sur l'axe longitudinal de la bande support.  This overlap zone has a width Ir between 2 and 4 fifths of the width L of the support strip and preferably a width Ir equal to 3 fifths of the width L of the support strip. Advantageously, the overlap zone extends longitudinally and is centered on the longitudinal axis of the support strip.

De préférence, ladite bande support présente une largeur L de 5 cm.  Preferably, said support strip has a width L of 5 cm.

Accessoirement, la zone non adhérente de chaque face de la bande support est obtenue par l'absence de produit adhésif. Selon une variante d'exécution de l'invention, la zone non adhérente de chaque face de la bande support est obtenue par dépôt d'une couche d'un produit non 5 adhésif. Ledit produit non adhésif est choisi parmi la liste des produits suivants : silicone, PVB, GMS ou cire. Par ailleurs, la bande support consiste soit en une bande de papier souple soit en une bande de mousse souple. 10 BREVE DESCRIPTION DES DESSINS  Incidentally, the non-adherent area of each side of the support strip is obtained by the absence of adhesive product. According to an alternative embodiment of the invention, the non-adherent zone of each face of the support strip is obtained by depositing a layer of a non-adhesive product. Said non-adhesive product is chosen from the list of the following products: silicone, PVB, GMS or wax. In addition, the support strip consists of either a flexible paper strip or a flexible foam strip. 10 BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION DETAILLEE DE L'INVENTION En référence à la figure 1, le ruban adhésif 1 suivant l'invention est conditionné sur une bobine 2 ou sur tout support équivalent. Ledit ruban adhésif 1, en référence aux figures 2 et 3, comprend une bande de support souple 3 munie sur une première face 4 d'une première bande de colle longitudinale 5 s'étendant depuis un premier bord de la bande support 3, ladite première bande de colle 5 ne couvrant que partiellement la première face de la bande support 3, et sur la face opposée d'une seconde bande de colle longitudinale 6 s'étendant depuis le bord opposé de ladite bande support 3, ladite seconde bande de colle 6 ne couvrant que partiellement la face opposée de la bande support 3. ~o La première bande de colle 5 de la première face de la bande support 3 présente une largeur 1 comprise entre 3 et 4 cinquièmes de la largeur L de la bande support 3 et la seconde bande de colle 6 longitudinale s'étend au droit de la zone non adhérente de la première face de la bande support 3 et présente une largeur comprise entre 1 et 2 cinquième de la largeur L de la bande support 3. 15 On entend par zone non adhérente la ou les zones de la bande support qui ne comporte pas de colle et qui ne permet donc pas l'adhésion du ruban sur une pièce de carrosserie. On observera que la première bande de colle 5 présente une largeur supérieure à la moitié de la largeur L de la bande support 3 permettant ainsi d'assurer 20 simultanément l'étanchéité de l'interstice entre deux pièces de carrosserie tout en assurant la protection d'une pièce de carrosserie adjacente qui doit également être protégée par un film protecteur. Ainsi en référence à la figure 4, la première bande de colle 5 du ruban adhésif 1 suivant l'invention est positionnée sur la paroi intérieure 7 d'une première pièce de 25 carrosserie 8, en l'espèce la portière avant droite d'une voiture, et la seconde bande de colle 6 dudit ruban 1 est positionnée sur la paroi extérieure 9 d'une seconde pièce de carrosserie 10 adjacente à la première, en l'occurrence la portière arrière droite de ladite voiture. On entend par paroi intérieure 7 de la première pièce de carrosserie 8 la paroi de ladite pièce de carrosserie 8 s'étendant au droit de l'interstice 11 formé 30 entre les deux pièce de carrosserie 8 et 10. Ainsi, une partie de la première bande de colle 5 du ruban adhésif 1 s'étend à l'extérieur entre les deux pièces de carrosserie 8 et 10. Un film protecteur 12 peut ainsi être collé sur la partie de la première bande de colle 5 afin de protéger l'ensemble de la seconde pièce de carrosserie 10, la première pièce de carrosserie devant être peinte.  DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, the adhesive tape 1 according to the invention is packaged on a spool 2 or on any equivalent support. Said adhesive tape 1, with reference to FIGS. 2 and 3, comprises a flexible support strip 3 provided on a first face 4 with a first longitudinal adhesive strip 5 extending from a first edge of the support strip 3, said first adhesive strip 5 covering only partially the first face of the support strip 3, and on the opposite side of a second longitudinal adhesive strip 6 extending from the opposite edge of said support strip 3, said second adhesive strip 6 covering only partially the opposite face of the support strip 3. ~ o The first adhesive strip 5 of the first face of the support strip 3 has a width 1 of between 3 and 4 fifths of the width L of the support strip 3 and the second longitudinal glue strip 6 extends to the right of the non-adherent zone of the first face of the support strip 3 and has a width of between 1 and 2 fifth of the width L of the support strip 3. non a zone dhérente the zone or zones of the support strip which does not contain glue and which therefore does not allow the adhesion of the tape to a bodywork part. It will be observed that the first adhesive strip 5 has a width greater than half the width L of the support strip 3 thus making it possible to simultaneously seal the gap between two bodywork parts while ensuring the protection of an adjacent bodywork part which must also be protected by a protective film. Thus, with reference to FIG. 4, the first adhesive strip 5 of the adhesive tape 1 according to the invention is positioned on the inner wall 7 of a first body part 8, in this case the right front door of a car, and the second adhesive strip 6 of said ribbon 1 is positioned on the outer wall 9 of a second body part 10 adjacent to the first, in this case the right rear door of said car. By inner wall 7 of the first bodywork part 8 is meant the wall of said bodywork part 8 extending in line with the gap 11 formed between the two bodywork parts 8 and 10. Thus, part of the first body part 8 adhesive strip 5 of the adhesive tape 1 extends outside between the two body parts 8 and 10. A protective film 12 can thus be glued to the part of the first adhesive strip 5 to protect the entire the second body part 10, the first piece of bodywork to be painted.

Selon une variante d'exécution du ruban adhésif 1 conforme à l'invention, en référence à la figure 5, une partie de la première bande de colle 5 de la première face de la bande support 3 s'étend au droit d'une partie de la seconde bande de colle 6 de la face opposée de ladite bande support 3 pour former une zone de recouvrement 13 de largeur Ir. io De la même manière que précédemment, la première bande de colle 5 de la première face de la bande support 3 présente une largeur 1 comprise entre 3 et 4 cinquièmes de la largeur L de la bande support 3 Par ailleurs, la seconde bande de colle 6 longitudinale s'étend depuis le bord opposé de la bande support 3 et présente également une largeur comprise entre 3 et 15 4 cinquièmes de la largeur L de ladite bande support 3. Ainsi, la zone de recouvrement 13 présente une largeur Ir comprise entre 1 et 3 cinquièmes de la largeur L de la bande support. De préférence, ladite zone de recouvrement 13 présente une largeur Ir égale à 3 cinquièmes de la largeur L de la bande support 3.  According to an alternative embodiment of the adhesive tape 1 according to the invention, with reference to FIG. 5, part of the first adhesive strip 5 of the first face of the support strip 3 extends to the right of a part the second adhesive strip 6 of the opposite face of said support strip 3 to form a covering zone 13 of width Ir. In the same manner as above, the first adhesive strip 5 of the first face of the support strip 3 has a width 1 between 3 and 4 fifths of the width L of the support strip 3 Moreover, the second longitudinal strip of glue 6 extends from the opposite edge of the support strip 3 and also has a width of between 3 and 4 4 fifths of the width L of said support strip 3. Thus, the overlap zone 13 has a width Ir of between 1 and 3 fifths of the width L of the support strip. Preferably, said overlap zone 13 has a width Ir equal to 3 fifths of the width L of the support strip 3.

20 De plus, ladite zone de recouvrement 13 s'étend longitudinalement et est centrée sur l'axe longitudinal de la bande support 3. Dans un mode de réalisation préféré, la bande support 3 présente une largeur L de 5 cm. Le ruban adhésif pourra être obtenu par tout procédé d'enduction d'une bande 25 support 3 sur ses deux faces bien connu de l'Homme du Métier. Ainsi, la zone non adhérente de chaque face de la bande support 3 pourra être obtenue par l'absence de produit adhésif. Alternativement, la zone non adhérente de chaque face de la bande support 3 pourra être obtenue par le dépôt d'une couche d'un produit non adhésif sur une 30 largeur définie par-dessus une couche de colle déposée sur l'ensemble des deux faces de ladite bande support 3, ledit produit non adhésif étant, par exemple, choisi parmi la liste des produits suivants : silicone, PVB, GMS ou cire. Par ailleurs, la bande support 3 consiste soit en une bande de papier souple soit en une bande de mousse souple. s Enfin, il est bien évident que les exemples que l'on vient de donner ne sont que des exemples de réalisation particuliers en aucun cas limitatifs quant aux domaines d'application de l'invention.In addition, said overlap zone 13 extends longitudinally and is centered on the longitudinal axis of the support strip 3. In a preferred embodiment, the support strip 3 has a width L of 5 cm. The adhesive tape may be obtained by any method of coating a support strip 3 on both sides well known to those skilled in the art. Thus, the non-adherent zone of each face of the support strip 3 can be obtained by the absence of adhesive product. Alternatively, the non-adherent zone of each face of the support strip 3 can be obtained by depositing a layer of a non-adhesive product over a defined width over a layer of adhesive deposited on both faces. of said carrier strip 3, said non-adhesive product being, for example, selected from the list of the following products: silicone, PVB, GMS or wax. Furthermore, the support strip 3 consists of either a flexible paper strip or a flexible foam strip. Finally, it is obvious that the examples which have just been given are only particular examples of embodiments which are in no way limiting as to the fields of application of the invention.
