Definitions
- the invention relates to the manufacturing method and the machine for manufacturing self-adhesive articles as well as the self-adhesive articles obtained.
- a special feature of these self-adhesive articles is that they consist of two sheet materials, the second covering a portion of the first. Naturally the adhesive surfaces are protected by protective papers. When the user applies this sticker against a transparent surface, we see through the window the second material surrounded by the first material, while the face of the opposite sticker lets see only the first material.
- the method for mass production of self-adhesive articles according to the invention is defined by claim 1, the manufacturing machine by claim 5 and the self-adhesive article obtained by claim 6.
- Figures 1 and 2 show a self-adhesive article 1 cut according to an external contour and constituted by a support 3, which can be made of synthetic or natural material, woven or not and whose face 4 is adhesive-coated and covered by a protective paper 5 cut according to a closed contour 9.
- a support 3 which can be made of synthetic or natural material, woven or not and whose face 4 is adhesive-coated and covered by a protective paper 5 cut according to a closed contour 9.
- a piece of sheet 6 of a second material 7, which is adhesive is applied to it and is covered on its free face by a protective paper 8.
- This piece 6 has the same outline as the closed contour 9 of the hole in the cutout of the first protective paper 5.
- the support 3 may have an adhesive side 4 or else be made of an adhesive material. If it is adhesive, the layer of adhesive material 4 has preferably been laminated to obtain a calibrated coating.
- the second sheet material may either be made entirely of adhesive material, for example synthetic gum or of an adhesive material at least on one side, protected by the protective paper.
- the protective papers 5 and 8 will preferably be double-sided silicone.
- This machine 1 is fed with the first strip 2 from a feed roller 11 and with the second strip 6 from the feed roller 12.
- the first strip 2 consisting of an adhesive-coated support protected by a protective paper 5, passes in front of a first cutting roller 13, which precisely cuts out for each article, according to a closed contour 9, a portion of the protective paper 5, and this without damaging the adhesive-coated support.
- the strip 2 which has become 21 passes in front of an evacuation device 14 which removes the cut of protective paper, for example with a mobile device with vacuum suction cup (not shown) or any other known system.
- the strip thus obtained 22 joins the second strip 6, so that the face of the strip 6 which does not carry protective paper is applied to the face of the strip 22 carrying a protective paper cut for each article according to the contour 9.
- the second cutting roller 15 has cutting impressions similar to those of the first cutting roller 13 and rotates in perfect synchronism with 13 thanks to the synchronization means 16, so as to cut only the strip 6 according to a contour coinciding with the hole of the cutting protective paper 5 of the underlying strip 22.
- the part cut from the strip 6 now remains glued to the adhesive side 4 of the support 3 of the strip 2 which becomes 23 after this operation. While the strip 23 advances towards the next operation, the cut strip 6 has become a draft 6 ′ and is directed by the means 15 and 17 to peel off the strip 23 without problem thanks to the protective paper 5 of the first strip.
- the strip 6 ′ can be separated into its components, the skin 8 ′ of the protective paper 8 wound on a reel and the skin 7 ′ of the adhesive material 7 wound on another reel and can be reused as material first.
- the strip 23 now passes through a station cutting the outer contour of the article 1 so that it can be separated from the strip and finally an ejection and storage equipment 19 separates the articles 1 from the strip 24, for example in a pile, while the body 25 will be wound on a towed reel.
- the cutting rollers preferably have on their surface several identical cutting imprints, for example six per circumference, and are supported on anvil cylinders.
- the hardness, etching and finish of each of these cylinders are adapted to the required operation.
- the cutting rollers are synchronized with each other, in particular the rollers 13, 15 and 18 by means of the intermediate wheels 16 to guarantee the coincidence of the cuts along the internal contour 9, respectively the arrangement of the external contour of the article compared to 9.
Description
L'invention concerne le procédé de fabrication et la machine de fabrication d'articles autocollants ainsi que les articles autocollants obtenus. Une particularité de ces articles autocollants est qu'ils sont constitués de deux matières en feuille, la seconde recouvrant une portion de la première. Naturellement les surfaces adhésives sont protégées par des papiers protecteurs. Lorsque l'usager applique cet autocollant contre une surface transparente, on voit à travers la vitre la seconde matière entourée de la première matière, alors que la face de l'autocollant opposée ne laisse voir que la première matière.The invention relates to the manufacturing method and the machine for manufacturing self-adhesive articles as well as the self-adhesive articles obtained. A special feature of these self-adhesive articles is that they consist of two sheet materials, the second covering a portion of the first. Naturally the adhesive surfaces are protected by protective papers. When the user applies this sticker against a transparent surface, we see through the window the second material surrounded by the first material, while the face of the opposite sticker lets see only the first material.
Le procédé de fabrication en série d'articles autocollants selon l'invention est défini par la revendication 1, la machine de fabrication par la revendication 5 et l'article autocollant obtenu par la revendication 6.The method for mass production of self-adhesive articles according to the invention is defined by claim 1, the manufacturing machine by claim 5 and the self-adhesive article obtained by
Pour mieux comprendre l'invention et ses avantages, l'article autocollant, le procédé de fabrication et la machine de fabrication selon l'invention seront décrits en détail à l'aide de formes d'exécution données à titre d'exemples et en se référant aux dessins dans lesquels
- la fig. 1 représente une coupe éclatée d'un article autocollant,
- la fig. 2 représente une vue en plan du même article avec des parties arrachées
- et la fig. 3 représente une machine de fabrication d'un tel article autocollant.
- fig. 1 represents an exploded section of a self-adhesive article,
- fig. 2 shows a plan view of the same article with parts torn off
- and fig. 3 shows a machine for manufacturing such a self-adhesive article.
Les figures 1 et 2 montrent un article autocollant 1 découpé selon un contour extérieur et constitué par un support 3, qui peut être fait de matière synthétique ou naturelle, tissé ou non et dont la face 4 est adhésivée et recouverte par un papier protecteur 5 découpé selon un contour fermé 9. A l'intérieur de ce contour 9, il n'y a pas de papier protecteur, mais une pièce en feuille 6 d'une seconde matière 7, qui est adhésive, y est appliquée et est recouverte sur sa face libre par un papier protecteur 8. Cette pièce 6 a le même contour que le contour fermé 9 du trou de la découpe du premier papier protecteur 5.Figures 1 and 2 show a self-adhesive article 1 cut according to an external contour and constituted by a support 3, which can be made of synthetic or natural material, woven or not and whose face 4 is adhesive-coated and covered by a protective paper 5 cut according to a closed contour 9. Inside this contour 9, it there is no protective paper, but a piece of
Il est clair que le support 3 peut comporter une face adhésivée 4 ou bien être fait en une matière adhésive. S'il est adhésivé la couche de matière adhésive 4 a été de préférence laminée pour obtenir un revêtement calibré. De même, la seconde matière en feuille peut être soit constituée complètement en matière adhésive, par exemple de la gomme synthétique ou en une matière adhésivée au moins sur une face, protégée par le papier protecteur. Les papiers protecteurs 5 et 8 seront de préférence siliconés double-face.It is clear that the support 3 may have an adhesive side 4 or else be made of an adhesive material. If it is adhesive, the layer of adhesive material 4 has preferably been laminated to obtain a calibrated coating. Likewise, the second sheet material may either be made entirely of adhesive material, for example synthetic gum or of an adhesive material at least on one side, protected by the protective paper. The protective papers 5 and 8 will preferably be double-sided silicone.
Pour fabriquer de tels articles autocollants 1, on utilise le procédé de fabrication selon l'invention et qui apparaîtra dans la description ci-après de la machine de fabrication représentée à la fig. 3.To manufacture such self-adhesive articles 1, the manufacturing method according to the invention is used and which will appear in the description below of the manufacturing machine shown in FIG. 3.
Cette machine 1 est alimentée avec la première bande 2 depuis un rouleau d'alimentation 11 et avec la seconde bande 6 depuis le rouleau d'alimentation 12. La première bande 2, constituée d'un support adhésivé protégé par un papier protecteur 5, passe devant un premier rouleau coupeur 13, qui découpe avec précision pour chaque article, selon un contour fermé 9, une portion du papier protecteur 5, et cela sans entamer le support adhésivé. Après cette opération, la bande 2 devenue 21 passe devant un équipement d'évacuation 14 qui enlève la découpe de papier protecteur par exemple avec un dispositif mobile à ventouse à dépression (non représenté) ou tout autre système connu. La bande ainsi obtenue 22 rejoint la seconde bande 6, de façon que la face de la bande 6 qui ne porte pas de papier protecteur s'applique sur la face de la bande 22 portant un papier protecteur découpé pour chaque article selon le contour 9. Ces deux bandes 22 et 6 accolées passent face à un second rouleau coupeur 15, la bande 6 du côté du rouleau coupeur. Le second rouleau coupeur 15 comporte des empreintes de découpe similaires à celles du premier rouleau coupeur 13 et tourne en parfait synchronisme avec 13 grâce aux moyens de synchronisation 16, de façon à découper seulement la bande 6 selon un contour coïncidant avec le trou de la découpe du papier protecteur 5 de la bande sous-jacente 22. La partie découpée dans la bande 6 reste maintenant collée à la face adhésivée 4 du support 3 de la bande 2 qui devient 23 après cette opération. Tandis que la bande 23 avance vers la prochaine opération, la bande 6 découpée est devenue une dépouille 6′ et est dirigée par les moyens 15 et 17 pour se peler de la bande 23 sans problème grâce au papier protecteur 5 de la première bande. La bande 6′ peut être séparée en ses composants, la dépouille 8′ du papier protecteur 8 s'enroulant sur une bobine et la dépouille 7′ de la matière adhésive 7 s'enroulant sur une autre bobine et pouvant être réutilisée en tant que matière première.This machine 1 is fed with the first strip 2 from a
La bande 23 passe maintenant dans une station découpant le contour extérieur de l'article 1 pour qu'il puisse être séparé de la bande et enfin un équipement d'éjection et de stockage 19 sépare de la bande 24 les articles 1 et les conserve, par exemple dans une pile, tandis que la dépouille 25 sera enroulée sur une bobine tractée.The
Les rouleaux coupeurs comportent à leur surface de préférence plusieurs empreintes identiques de découpe, par exemple six par circonférence, et s'appuient sur des cylindres enclumes. La dureté, la gravure et la finition de chacun de ces cylindres sont adaptées à l'opération requise.The cutting rollers preferably have on their surface several identical cutting imprints, for example six per circumference, and are supported on anvil cylinders. The hardness, etching and finish of each of these cylinders are adapted to the required operation.
Les rouleaux coupeurs sont synchronisés entre eux, en particulier les rouleaux 13, 15 et 18 grâce aux roues intermédiaires 16 pour garantir la coïncidence des découpes selon le contour intérieur 9, respectivement la disposition du contour extérieur de l'article par rapport à 9.The cutting rollers are synchronized with each other, in particular the
On voit que tout l'agencement permet de dérouler les opérations sans risque de collage dans la machine de fabrication, le papier protecteur se trouvant toujours du côté des bandes où celles-ci prennent appui.It can be seen that the entire arrangement allows operations to be carried out without risk of sticking in the manufacturing machine, the protective paper always being on the side of the strips where these rest.
Ainsi une production de série d'articles autocollants est facilement réalisable et peut fonctionner sans autre pour 3000 articles fabriqués par heure.Thus a series production of self-adhesive articles is easily achievable and can function without other for 3000 articles manufactured per hour.
