Definitions

  • the present invention relates to a coating group for applying a coating substance to a flat support.
  • the invention also relates to a printing machine for flat supports equipped with a group for applying a coating on flat supports.
  • a printing machine is used in the packaging industry for printing flat supports, such as sheets, or a continuous strip of paper or cardboard.
  • the machine includes several successive stations.
  • a first station located furthest upstream is an introduction station which introduces the planar support.
  • the insertion station supplies several printing stations, in the form of one or more printing groups placed one after the other. Each of the printing groups prints a specific color with an ink having the equivalent coloring.
  • a receiving station which collects the printed support with an image is provided at the end of the machine.
  • the printing machines include one or more printing groups, depending on the number of colors desired.
  • the support is moved longitudinally from upstream to downstream from the introduction station, towards the printing units, up to the reception station. In order to obtain a final quality image on the printed medium, it is especially necessary that all the patterns of different colors overlap exactly. It is also necessary that the printed dots are not distorted.
  • the selection of packaging is mainly based on a quality level criterion chosen according to the product to be packaged.
  • the control of the support after printing is still done visually.
  • the operator searches for all types of faults with careful observation of the printed medium and rejects the non-conforming supports.
  • the quality of the printing obtained depends not only on the quality of the printing machines, the quality of the inks used, but also on the quality of the media introduced at the machine input. Indeed, in the case of cardboard and for the same support, the surface may have irregularities, leading to different ink absorption properties, depending on the nature of the cellulose fibers constituting the support.
  • the printing affixed will show absences or surplus ink, variations in intensity of the color (s), and other defects. Indeed, when the drop of ink arrives at the surface of the support, its spreading will not be uniform. The image obtained is distorted by a multitude of printed dots, having a much larger surface area than that expected and visible to the naked eye, alternating with dots appearing to be printed correctly. In addition, the ink pigments are absorbed by the cardboard, resulting in a poorer pigmentation density leading to a dull image.

Description

La présente invention concerne un groupe d'enduction pour appliquer une substance d'enduction sur un support plan. L'invention se rapporte également à une machine d'impression de supports plans équipée avec un groupe pour appliquer une enduction sur les supports plans.The present invention relates to a coating group for applying a coating substance to a flat support. The invention also relates to a printing machine for flat supports equipped with a group for applying a coating on flat supports.

Une machine d'impression est utilisée dans l'industrie de l'emballage pour l'impression de supports plans, tels que des feuilles, ou une bande continue de papier ou de carton. La machine comprend plusieurs stations successives. Une première station située la plus en amont est une station d'introduction qui introduit le support plan. La station d'introduction alimente plusieurs stations d'impression, sous la forme d'un ou de plusieurs groupes imprimeurs placés les uns à la suite des autres. Chacun des groupes imprimeurs imprime une couleur spécifique avec une encre présentant la coloration équivalente. Une station de réception qui collecte le support imprimé avec une image est prévue en fin de machine.A printing machine is used in the packaging industry for printing flat supports, such as sheets, or a continuous strip of paper or cardboard. The machine includes several successive stations. A first station located furthest upstream is an introduction station which introduces the planar support. The insertion station supplies several printing stations, in the form of one or more printing groups placed one after the other. Each of the printing groups prints a specific color with an ink having the equivalent coloring. A receiving station which collects the printed support with an image is provided at the end of the machine.

Dans le cas de l'impression de feuilles de carton, plus particulièrement de carton ondulé, la technologie la plus fréquemment employée est l'impression en flexographie, avec utilisation de groupe flexo. L'impression digitale se développe également de plus en plus, avec utilisation de groupes imprimeurs munis de têtes d'impression digitales, par exemple de type jet d'encre. Cette technologie d'impression permet au fabriquant d'emballage de changer très rapidement de travail pour imprimer de nouvelles feuilles à partir d'un fichier informatique représentatif de l'emballage.In the case of the printing of sheets of cardboard, more particularly corrugated cardboard, the most frequently used technology is printing in flexography, with use of flexo group. Digital printing is also developing more and more, with the use of printing units fitted with digital printing heads, for example of the inkjet type. This printing technology allows the packaging manufacturer to quickly change jobs to print new sheets from a computer file representative of the packaging.

Les machines d'impression comprennent un ou plusieurs groupes imprimeurs, en fonction du nombre de couleurs souhaitées. Le support est déplacé longitudinalement de l'amont vers l'aval à partir de la station d'introduction, vers les groupes imprimeurs, jusqu'à la station de réception. Pour obtenir une image finale de qualité sur le support imprimé, il est notamment nécessaire que tous les motifs de couleurs différentes se superposent exactement. Il est également nécessaire que les points imprimés ne soient pas déformés.The printing machines include one or more printing groups, depending on the number of colors desired. The support is moved longitudinally from upstream to downstream from the introduction station, towards the printing units, up to the reception station. In order to obtain a final quality image on the printed medium, it is especially necessary that all the patterns of different colors overlap exactly. It is also necessary that the printed dots are not distorted.

La sélection des emballages se fait principalement selon un critère de niveau de qualité choisi en fonction du produit devant être emballé. Le contrôle du support après impression se fait encore actuellement de manière visuelle. L'opérateur recherche tous les types de défauts avec observation attentive du support imprimé et rejette le ou les supports non conformes.The selection of packaging is mainly based on a quality level criterion chosen according to the product to be packaged. The control of the support after printing is still done visually. The operator searches for all types of faults with careful observation of the printed medium and rejects the non-conforming supports.

La qualité de l'impression obtenue dépend non seulement de la qualité des machines d'impression, de la qualité des encres utilisées, mais également de la qualité des supports introduits en entrée machine. En effet dans le cas du carton et pour un même support, la surface peut présenter des irrégularités, conduisant à des propriétés différentes d'absorption de l'encre, en fonction de la nature des fibres de cellulose constitutives du support.The quality of the printing obtained depends not only on the quality of the printing machines, the quality of the inks used, but also on the quality of the media introduced at the machine input. Indeed, in the case of cardboard and for the same support, the surface may have irregularities, leading to different ink absorption properties, depending on the nature of the cellulose fibers constituting the support.

Il en découle que l'impression apposée va présenter des absences ou des surplus d'encre, des variations d'intensité de la ou des couleurs, et d'autres défauts encore. En effet, lorsque la goutte d'encre arrive au niveau de la surface du support, son étalement ne va pas être uniforme. L'image obtenue est dénaturée par une multitude de points imprimés, présentant une surface beaucoup plus importante que celle escomptée et visibles à l'œil nu, alternant avec des points apparaissant comme étant imprimés correctement. De plus, les pigments de l'encre sont absorbés par le carton, avec pour résultat une densité de pigmentation moins bonne conduisant à l'obtention d'une image terne.It follows that the printing affixed will show absences or surplus ink, variations in intensity of the color (s), and other defects. Indeed, when the drop of ink arrives at the surface of the support, its spreading will not be uniform. The image obtained is distorted by a multitude of printed dots, having a much larger surface area than that expected and visible to the naked eye, alternating with dots appearing to be printed correctly. In addition, the ink pigments are absorbed by the cardboard, resulting in a poorer pigmentation density leading to a dull image.

Exposé de l'inventionStatement of the invention

Un objectif principal de la présente invention consiste à améliorer la qualité d'impression d'une machine d'impression de supports plans, équipée avec au moins un groupe imprimeur. Un deuxième objectif est de réaliser une machine d'impression équipée avec un groupe permettant d'enduire toute ou partie de la surface des supports plans. Un troisième objectif est de résoudre les problèmes techniques mentionnés pour les machines de l'état de la technique. Un autre objectif encore est celui de réussir à insérer un groupe d'enduction dans une machine d'impression de supports plans.A main objective of the present invention consists in improving the printing quality of a printing machine for flat supports, equipped with at least one printing unit. A second objective is to produce a printing machine equipped with a group making it possible to coat all or part of the surface of the flat supports. A third objective is to solve the technical problems mentioned for the machines of the state of the art. Yet another objective is that of successfully inserting a coating group into a printing machine for flat supports.

Conformément à un aspect de la présente invention, un groupe d'enduction est utilisé pour appliquer une substance d'enduction sur toute une surface d'un support plan ou sur une partie d'une surface d'un support plan, dans une machine d'impression de supports plans comme défini dans la revendication 1.In accordance with one aspect of the present invention, a coating group is used to apply a coating substance to an entire surface of a planar support or to a portion of a surface of a planar support, in a machine for printing of flat supports as defined in claim 1.

Un support plan est défini, à titre d'exemple non exhaustif, comme étant en un matériau en feuille, en plaque, en bande continue tel que du papier, du carton plat, du carton ondulé, du carton ondulé contrecollé, du plastique flexible, par exemple du polyéthylène (PE), du polyéthylène téréphtalate (PET), du polypropylène biorienté (BOPP), ou d'autres polymères, ou d'autres matériaux encore. Le support plan est défini, à titre d'exemple non exhaustif, comme étant une feuille destinée à former une découpe, puis une boîte d'emballage.A flat support is defined, by way of non-exhaustive example, as being of a sheet, plate, continuous strip material such as paper, flat cardboard, corrugated cardboard, laminated corrugated cardboard, flexible plastic, for example polyethylene (PE), polyethylene terephthalate (PET), bioriented polypropylene (BOPP), or other polymers, or other materials. The flat support is defined, by way of non-exhaustive example, as being a sheet intended to form a cutout, then a packaging box.

Autrement dit, en prévoyant un groupe d'enduction directement monté dans la machine d'impression, la qualité de l'impression obtenue va être améliorée par le dépôt d'une substance d'enduction et avec récupération de cette même substance pour éviter les excès. Le résultat d'impression ne va plus être seulement tributaire du support de départ. L'enduction du support fait que les pigments restent en surface, évitant ainsi les phénomènes de marbrure.In other words, by providing a coating group directly mounted in the printing machine, the quality of the printing obtained will be improved by the deposition of a coating substance and with recovery of this same substance to avoid excess . The printing result will no longer be solely dependent on the starting medium. The coating of the support means that the pigments remain on the surface, thus avoiding mottling phenomena.

Selon un autre aspect encore de l'invention, une machine d'impression de supports plans, équipée avec au moins un groupe imprimeur, comprend au moins un groupe d'enduction, présentant une ou plusieurs caractéristiques techniques décrites ci-dessous et revendiquées.According to yet another aspect of the invention, a machine for printing flat supports, equipped with at least one printing unit, comprises at least one coating group, having one or more technical characteristics described below and claimed.

Exposé détaillé de modes de réalisation préférésDetailed description of preferred embodiments

Comme l'illustre la Figure 1, une machine d'impression 1 est utilisée pour imprimer des supports de type éléments en plaque, par exemple des feuilles en carton ondulé. A titre d'exemple principal de réalisation, la machine 1 est une machine d'impression digitale, qui reprend par exemple certains éléments constitutifs décrits dans le document US 6,471,430 . La machine 1 comprend notamment un ensemble de quatre groupes imprimeurs 2, disposés en ligne les uns à la suite des autres. Chacun des groupes imprimeurs 2 est muni d'au moins une tête d'impression digitale, par exemple sans contact, par exemple à jet d'encre. Les encres noir, cyan, magenta et jaune sont imprimées sur les feuilles.As the Figure 1 , a printing machine 1 is used to print supports of the plate element type, for example sheets of corrugated cardboard. As a main embodiment, the machine 1 is a digital printing machine, which for example uses certain constituent elements described in the document US 6,471,430 . The machine 1 notably comprises a set of four printing groups 2, arranged in line one after the other. Each of the printing units 2 is provided with at least one digital print head, for example without contact, for example with ink jet. Black, cyan, magenta and yellow inks are printed on the sheets.

Les feuilles sont introduites (Flèches F en Fig. 1) par une station d'alimentation (non représentée), montée en amont de la machine d'impression 1 (non représentée). Les feuilles sont ensuite saisies, transportées, circulent longitudinalement F, et sortent F imprimées au niveau d'une station de réception (non représentée), montée en aval de la machine d'impression 1. Deux séchoirs 3, avec des tubulures d'évacuation de vapeur d'eau, sont placés en aval des groupes imprimeurs 2.The leaves are introduced (Arrows F in Fig. 1 ) by a feed station (not shown), mounted upstream of the printing machine 1 (not shown). The sheets are then picked up, transported, run longitudinally F, and exit F printed at a reception station (not shown), mounted downstream of the printing machine 1. Two dryers 3, with evacuation pipes of steam, are placed downstream of the printing units 2.

La direction longitudinale est définie par référence à la trajectoire des feuilles dans la machine d'impression 1, selon son axe longitudinal médian. Les directions amont et aval sont définies en faisant référence au sens de déplacement selon la trajectoire des feuilles, suivant la direction longitudinale dans l'ensemble de la machine d'impression 1.The longitudinal direction is defined by reference to the path of the sheets in the printing machine 1, along its median longitudinal axis. The upstream and downstream directions are defined with reference to the direction of movement along the path of the sheets, in the longitudinal direction throughout the printing machine 1.

Les feuilles devant être imprimées sont transportées de l'amont vers l'aval par un tapis ou une bande métallique sans fin 4 qui est montée entre un premier cylindre transversal amont 5 et un deuxième cylindre transversal aval 6. Au moins l'un des deux cylindres transversaux 5 et 6 est entrainé en rotation (Flèche R en Fig. 1) au moyen d'un moteur, ce qui entraîne la bande 4. Les cylindres 5 et 6 et la bande 4 sont montés sur un châssis 7. Les feuilles restent plaquées sur la bande 4 dans son trajet supérieur et passent sous les groupes imprimeurs 2 et les modules de séchage 3, grâce à des caissons d'aspiration également appelés caissons vacuum.The sheets to be printed are transported from upstream to downstream by an endless belt or metal band 4 which is mounted between a first upstream transverse cylinder 5 and a second downstream transverse cylinder 6. At least one of the two transverse cylinders 5 and 6 is rotated (Arrow R in Fig. 1 ) by means of a motor, which drives the strip 4. The cylinders 5 and 6 and the strip 4 are mounted on a frame 7. The sheets remain pressed against the strip 4 in its upper path and pass under the printing units 2 and the drying modules 3, using suction boxes also called vacuum boxes.

Selon l'invention, la machine d'impression 1 comprend au moins un groupe d'enduction 8 et 9 pour appliquer une substance d'enduction sur toute ou partie d'une surface des supports plans.According to the invention, the printing machine 1 comprises at least one coating group 8 and 9 for applying a coating substance to all or part of a surface of flat supports.

Pour favoriser l'accroche et la tenue des encres qui vont être déposées par impression sur les feuilles de carton devant être imprimées, la machine d'impression 1 comprend favorablement un groupe d'enduction amont 8. Ce groupe d'enduction amont 8 est disposé en amont du premier groupe imprimeur 2, juste après la station d'alimentation. Le groupe d'enduction amont 8 est placé au droit du cylindre amont 5.To favor the adhesion and the hold of the inks which will be deposited by printing on the cardboard sheets to be printed, the printing machine 1 favorably comprises an upstream coating group 8. This upstream coating group 8 is arranged upstream of the first printing unit 2, just after the feed station. The upstream coating group 8 is placed in line with the upstream cylinder 5.

Le groupe d'enduction amont 8 applique une enduction, dans ce cas sur la totalité de la surface des feuilles vierge de toute impression. De cette manière, la surface est préparée avec un précouchage pour recevoir ultérieurement l'image devant être imprimée. La substance d'enduction est une solution aqueuse comprenant des polymères hydrosolubles. Pour faire sécher l'enduction, un séchoir 3 peut être intercalé entre le groupe d'enduction amont 8 et le premier groupe imprimeur 2.The upstream coating group 8 applies a coating, in this case on the entire surface of the sheets, blank of any printing. In this way, the surface is prepared with a pre-coating to subsequently receive the image to be printed. The coating substance is an aqueous solution comprising water-soluble polymers. To dry the coating, a dryer 3 can be interposed between the upstream coating group 8 and the first printing group 2.

Pour favoriser la tenue et la protection des encres qui sont déposées par impression sur les feuilles de carton venant d'être imprimées, la machine d'impression 1 comprend favorablement un groupe d'enduction aval 9. Ce groupe d'enduction aval 9 est disposé en aval du dernier groupe imprimeur 2, et en aval des séchoirs 3, juste avant la station de réception. Le groupe d'enduction aval 9 est placé au droit du cylindre aval 6.To promote the holding and protection of the inks which are deposited by printing on the cardboard sheets which have just been printed, the printing machine 1 favorably comprises a downstream coating group 9. This downstream coating group 9 is arranged downstream of the last printing unit 2, and downstream of the driers 3, just before the receiving station. The downstream coating group 9 is placed in line with the downstream cylinder 6.

Le groupe d'enduction aval 9 applique une enduction, dans ce cas sur la totalité de la surface des feuilles imprimées et ainsi sur l'image imprimée. De cette manière, la surface imprimée est recouverte avec un postcouchage pour protéger l'image venant d'être imprimée et séchée.The downstream coating group 9 applies a coating, in this case on the entire surface of the printed sheets and thus on the printed image. In this way, the printed surface is covered with a post-coating to protect the image that has just been printed and dried.

Comme les montrent les Figs. 2 à 5, le groupe d'enduction amont 8 et le groupe d'enduction aval 9 comprennent chacun un cylindre applicateur 11. Le cylindre applicateur 11 est positionné transversalement, i.e. perpendiculairement à la bande 4. Le cylindre applicateur 11 est entraîné en rotation (Flèche T en Fig. 3) pendant la phase de production. Le cylindre applicateur 11 est revêtu avec une couche homogène d'un matériau poreux présentant des propriétés d'élasticité et d'absorption de la substance, par exemple un caoutchouc souple 12.As the Figs. 2 to 5 , the upstream coating group 8 and the downstream coating group 9 each comprise an applicator cylinder 11. The applicator cylinder 11 is positioned transversely, ie perpendicular to the strip 4. The applicator cylinder 11 is rotated (Arrow T at Fig. 3 ) during the production phase. The applicator cylinder 11 is coated with a homogeneous layer of a porous material having elasticity and absorption properties of the substance, for example a flexible rubber 12.

Le cylindre applicateur 11 est apte à être positionné contre toute ou partie de la surface de la feuille, pour y appliquer la substance d'enduction, le précouchage ou le postcouchage. Les feuilles circulent dans le gap laissé entre le cylindre applicateur 11 et la bande 4. La substance d'enduction, le précouchage ou le postcouchage, va ainsi être déposée sur les feuilles de carton ondulé sur les cannelures et sur le fond entre les cannelures. Le carton ondulé de la feuille ne va pas être écrasé par le caoutchouc souple 12 du cylindre applicateur 11.The applicator cylinder 11 is able to be positioned against all or part of the surface of the sheet, in order to apply the coating substance, the pre-coating or the post-coating. The sheets circulate in the gap left between the applicator cylinder 11 and the strip 4. The coating substance, the pre-coating or the post-coating, will thus be deposited on the sheets of corrugated cardboard on the grooves and on the bottom between the grooves. The corrugated cardboard of the sheet will not be crushed by the flexible rubber 12 of the applicator cylinder 11.

Le groupe d'enduction amont 8 et le groupe d'enduction aval 9 comprennent chacun un cylindre tramé 13, également connu sous la dénomination de cylindre anilox. Le cylindre tramé 13 est entraîné en rotation (Flèche S en Fig. 3) pendant la phase de production. Le cylindre tramé 13 est positionné parallèlement au cylindre applicateur 11. Le cylindre tramé 13 est monté sensiblement côté aval par rapport à l'axe de rotation du cylindre applicateur 11. Lorsque le cylindre tramé 13 est en fonction, il se positionne contre le cylindre applicateur 11. Le cylindre tramé 13 recouvre le cylindre applicateur 11 avec la substance, d'enduction, le précouchage ou le postcouchage.The upstream coating group 8 and the downstream coating group 9 each comprise a screened cylinder 13, also known by the name of anilox cylinder. The screened cylinder 13 is rotated (arrow S in Fig. 3 ) during the production phase. The screened cylinder 13 is positioned parallel to the applicator cylinder 11. The screened cylinder 13 is mounted substantially downstream side with respect to the axis of rotation of the applicator cylinder 11. When the screened cylinder 13 is in operation, it is positioned against the applicator cylinder 11. The screened cylinder 13 covers the applicator cylinder 11 with the substance, coating, pre-coating or post-coating.

Le groupe d'enduction amont 8 et le groupe d'enduction aval 9 comprennent chacun un système d'approvisionnement 14. Le système d'approvisionnement 14 est muni d'un réservoir à substance, d'une pompe, de moyens de circulation de la substance (non représentés), et d'un dispositif 16 se plaquant contre le cylindre tramé 13 pour l'approvisionner en substance. Le système d'approvisionnement 14 permet d'approvisionner le cylindre tramé 13 avec la substance.The upstream coating group 8 and the downstream coating group 9 each comprise a supply system 14. The supply system 14 is provided with a substance reservoir, a pump, means for circulation of the substance (not shown), and a device 16 pressing against the screened cylinder 13 to supply it with substance. The supply system 14 makes it possible to supply the screened cylinder 13 with the substance.

Le dispositif est avantageusement du type chambre à racle 16. La chambre à racle 16 est positionnée parallèlement au cylindre tramé 13. La chambre à racle 16 peut être montée côté amont par rapport à l'axe de rotation du cylindre tramé 13. La chambre à racle comprend deux racles définissant un volume pour remplir les alvéoles du cylindre tramé 13 avec la substance d'enduction.The device is advantageously of the doctor blade type 16. The doctor blade chamber 16 is positioned parallel to the screened cylinder 13. The doctor blade chamber 16 can be mounted upstream side with respect to the axis of rotation of the screened cylinder 13. The chamber doctor blade comprises two doctor blades defining a volume for filling the cells of the screened cylinder 13 with the coating substance.

Pour passer d'une phase de non utilisation et/ou de nettoyage (voir Fig. 2) à la phase de production (voir Fig. 3), la chambre à racle 16 pivote (Flèche PU en Fig. 2) grâce à un vérin 17 se rétractant (Flèche U en Fig. 2) et un axe de pivotement, d'une position basse à une position plaquée contre le cylindre tramé 13. Dans la position basse, la chambre à racle 16 se retrouve par exemple parallèle à la bande 4. Pour passer à la phase de nettoyage de la chambre à racle 16, la chambre à racle 16 pivote (Flèche PD en Fig. 3) grâce au vérin 17 et à l'axe de pivotement, de la position plaquée contre le cylindre tramé 13 à la position basse.To go from a phase of non-use and / or cleaning (see Fig. 2 ) during the production phase (see Fig. 3 ), the doctor blade chamber 16 pivots (PU arrow in Fig. 2 ) thanks to a retracting cylinder 17 (U arrow in Fig. 2 ) and a pivot axis, from a low position to a position pressed against the screened cylinder 13. In the low position, the doctor blade chamber 16 is found for example parallel to the strip 4. To pass to the cleaning phase of the doctor blade chamber 16, the doctor blade chamber 16 pivots (Arrow PD in Fig. 3 ) thanks to the jack 17 and to the pivot axis, from the position pressed against the screened cylinder 13 to the low position.

Selon l'invention, le groupe d'enduction amont 8 et le groupe d'enduction aval 9 comprennent en outre un système de récupération 18. Lorsque le système de récupération 18 est en fonction, il se positionne contre le cylindre applicateur 11 et plus particulièrement contre la couche homogène du matériau poreux 12 du cylindre applicateur 11. Le système de récupération 18 peut être monté à proximité et en aval du cylindre tramé 13, l'aval étant défini par rapport au sens de rotation T du cylindre applicateur 11. Le cylindre applicateur 11 redevient ainsi propre à chaque nouvelle révolution, grâce au système de récupération 18.According to the invention, the upstream coating group 8 and the downstream coating group 9 further comprise a recovery system 18. When the recovery system 18 is in operation, it is positioned against the applicator cylinder 11 and more particularly against the homogeneous layer of porous material 12 of the applicator cylinder 11. The recovery system 18 can be mounted near and downstream of the screened cylinder 13, the downstream being defined relative to the direction of rotation T of the applicator cylinder 11. The cylinder applicator 11 thus becomes specific to each new revolution, thanks to the recovery system 18.

Etant donné que l'impression se fait en feuille à feuille, les feuilles arrivent en continue en étant transportées par la bande 4. Les feuilles sont séparées les unes des autres par un écart de quelques centimètres. De ce fait, de la substance reste sur le cylindre applicateur 11, ce dernier étant continuellement approvisionné par la chambre à racle 16. Le cylindre applicateur 11 tourne en continu T, et au moment de sa rotation au niveau de l'écart entre deux feuilles, la substance ne sert pas à enduire la surface des feuilles, et peut être récupérée par le système de récupération 18.Since the printing is done sheet by sheet, the sheets arrive continuously being transported by the strip 4. The sheets are separated from each other by a gap of a few centimeters. Therefore, the substance remains on the applicator cylinder 11, the latter being continuously supplied by the doctor blade chamber 16. The applicator cylinder 11 rotates continuously T, and at the time of its rotation at the gap between two sheets , the substance is not used to coat the surface of the leaves, and can be recovered by the recovery system 18.

Les feuilles utilisée pour être imprimées peuvent avoir un format différent par exemple une laize inférieure à la longueur maximale d'enduction du cylindre applicateur 11. Le système de récupération 18 récupère aussi de la substance qui reste sur le cylindre applicateur 11, mais en dehors du format de la feuille.The sheets used to be printed may have a different format, for example a width less than the maximum coating length of the applicator cylinder 11. The recovery system 18 also recovers substance which remains on the applicator cylinder 11, but outside of the sheet format.

Le système de récupération 18 peut être muni d'une racle 19 insérée dans un porte-racle 21. Le porte-racle 21 avec sa racle 19 sont positionnés parallèlement au cylindre applicateur 11. En position active, l'arête de la racle 19 est apte à être positionnée et à s'appuyer contre la couche homogène du matériau poreux 12. L'arête de la racle 19 est apte à racler le cylindre applicateur 11, pendant sa rotation T, de façon à récupérer un excès de substance sur le cylindre applicateur 11.The recovery system 18 can be provided with a doctor blade 19 inserted in a doctor blade holder 21. The doctor blade holder 21 with its doctor blade 19 are positioned parallel to the applicator cylinder 11. In the active position, the edge of the doctor blade 19 is able to be positioned and to bear against the homogeneous layer of porous material 12. The edge of the doctor blade 19 is suitable for scraping the applicator cylinder 11, during its rotation T, so as to recover an excess of substance on the cylinder applicator 11.

Le système de récupération 18 comprend préférentiellement des moyens d'aspiration 22 de la substance, précouchage ou postcouchage. Les moyens d'aspiration 22 peuvent être montés sous la racle 19, pour aspirer l'excès de substance récupéré par la racle 19. Le surplus de substance s'accumule en effet sous la racle 19 lorsque le cylindre applicateur 11 tourne. Les moyens d'aspiration 22 viennent aspirer ce surplus de substance.The recovery system 18 preferably comprises suction means 22 for the substance, pre-coating or post-coating. The suction means 22 can be mounted under the doctor blade 19, to suck up the excess substance recovered by the doctor blade 19. The surplus substance accumulates in effect under the doctor blade 19 when the applicator cylinder 11 rotates. The suction means 22 suck up this excess substance.

Les moyens d'aspiration 22 peuvent se présenter sous la forme d'un tuyau perforé plaqué contre l'extrémité du porte-racle 21, et parallèle à la racle 19. Les moyens d'aspiration 22 sont connectés à une tubulure, à une pompe, et à un réservoir de stockage pour la substance.The suction means 22 can be in the form of a perforated pipe pressed against the end of the doctor blade holder 21, and parallel to the doctor blade 19. The suction means 22 are connected to a tube, to a pump , and a storage tank for the substance.

Le système de récupération 18 comprend de manière avantageuse des moyens de déplacement 23, par exemple de type vérin. Ces moyens de déplacement 23 permettent de faire passer le système de récupération 18 avec porte-racle 21, racle 19 et moyens d'aspiration 22, d'une position active (voir Figs. 3 et 5) à une position inactive (voir Figs. 2 et 4) et réciproquement. En position active, la racle 19 racle la surface de la couche homogène du matériau poreux 12. En position inactive, la racle 19 est éloignée du cylindre applicateur 11.The recovery system 18 advantageously comprises displacement means 23, for example of the jack type. These displacement means 23 make it possible to pass the recovery system 18 with doctor blade holder 21, doctor blade 19 and suction means 22, from an active position (see Figs. 3 and 5 ) to an inactive position (see Figs. 2 and 4 ) and reciprocally. In the active position, the doctor blade 19 scrapes the surface of the homogeneous layer of the porous material 12. In the inactive position, the doctor blade 19 is moved away from the applicator cylinder 11.

De manière favorable, le groupe d'enduction amont 8 et le groupe d'enduction aval 9 comprennent en outre un système de nettoyage 24. Le système de nettoyage 24 peut être monté à proximité et en aval du cylindre tramé 13, l'aval étant défini par rapport au sens de rotation T du cylindre applicateur 11. Le système de nettoyage 24 peut ainsi être monté côté aval par rapport au système de récupération 18. Le système de nettoyage 24 est apte à être positionné contre le cylindre applicateur 11, et plus particulièrement contre la couche homogène du matériau poreux 12, et apte à nettoyer le cylindre applicateur 11, de façon à enlever de la poussière.Favorably, the upstream coating group 8 and the downstream coating group 9 also comprise a cleaning system 24. The cleaning system 24 can be mounted near and downstream of the screened cylinder 13, the downstream being defined with respect to the direction of rotation T of the applicator cylinder 11. The cleaning system 24 can thus be mounted on the downstream side with respect to the recovery system 18. The cleaning system 24 is capable of being positioned against the applicator cylinder 11, and more particularly against the homogeneous layer of the porous material 12, and capable of cleaning the applicator cylinder 11, so as to remove dust.

Le système de nettoyage 24 comprend de préférence un rouleau 26 avec un manchon. Le rouleau 26 est positionné parallèlement au cylindre applicateur 11. Le manchon comprend une matière possédant une propriété d'absorption de la substance. La matière du manchon du rouleau 26 est choisie dans le groupe comprenant les textiles ou analogues de type chiffon.The cleaning system 24 preferably comprises a roller 26 with a sleeve. The roller 26 is positioned parallel to the applicator cylinder 11. The sleeve comprises a material having a property of absorbing the substance. The material of the sleeve of the roller 26 is chosen from the group comprising textiles or the like of the rag type.

Le système de nettoyage 24 comprend avantageusement un dispositif d'arrosage 27, monté au-dessus du rouleau manchonné 26. Le dispositif d'arrosage 27 est positionné parallèlement au rouleau 26 et au cylindre applicateur 11. Le dispositif d'arrosage 27 peut se présenter sous la forme d'un tuyau perforé alimenté par de l'eau ou toute autre solution de nettoyage à base aqueuse. Le dispositif d'arrosage 27 vient humidifier le rouleau 26. Le dispositif d'arrosage 27 permet d'éviter que le textile devienne abrasif pour le caoutchouc souple 12 du cylindre applicateur 11. Lorsque le rouleau 26 du système de nettoyage 24 est en fonction, il se positionne contre la couche homogène du matériau poreux 12 pour nettoyer et pour humidifier le le cylindre applicateur 11.The cleaning system 24 advantageously comprises a sprinkler device 27, mounted above the sleeved roller 26. The sprinkler device 27 is positioned parallel to the roller 26 and to the applicator cylinder 11. The sprinkler device 27 can be provided in the form of a perforated pipe supplied with water or any other aqueous-based cleaning solution. The sprinkler device 27 moistens the roller 26. The sprinkler device 27 prevents the textile from becoming abrasive for the flexible rubber 12 of the applicator cylinder 11. When the roller 26 of the cleaning system 24 is in operation, it is positioned against the homogeneous layer of porous material 12 to clean and to moisten the applicator cylinder 11.

Le système de nettoyage 24 comprend favorablement des moyens de déplacement. Ces moyens de déplacement font passer le système de nettoyage 24 avec rouleau manchonné 26 et dispositif d'arrosage 27, d'une position active contre le cylindre applicateur 11 (voir Figs. 4 et 5) à une position inactive écartée du cylindre applicateur 11 (voir Figs. 2 et 3), et réciproquement.The cleaning system 24 favorably comprises displacement means. These displacement means pass the cleaning system 24 with sleeved roller 26 and sprinkler device 27 from an active position against the applicator cylinder 11 (see Figs. 4 and 5 ) in an inactive position away from the applicator cylinder 11 (see Figs. 2 and 3 ), and reciprocally.

L'opérateur choisi la position des éléments constitutifs du groupe d'enduction amont 8 et/ou du groupe d'enduction aval 9. Dans une position inactive de non fonctionnement (Fig. 2), le cylindre tramé 13 est éloigné du cylindre applicateur 11. La chambre à racle 16 est en position basse. Le système de récupération 18, avec porte-racle 21, racle 19 et moyens d'aspiration 22, est éloigné du cylindre applicateur 11. Le système de nettoyage 24, avec rouleau manchonné 26 et dispositif d'arrosage 27, est écarté du cylindre applicateur 11.The operator chooses the position of the components of the upstream coating group 8 and / or the downstream coating group 9. In an inactive position of non-operation ( Fig. 2 ), the screened cylinder 13 is distant from the applicator cylinder 11. The doctor blade chamber 16 is in the low position. The recovery system 18, with doctor blade holder 21, doctor blade 19 and suction means 22, is remote from the applicator cylinder 11. The cleaning system 24, with sleeved roller 26 and sprinkler device 27, is separated from the applicator cylinder 11.

Dans une position de production (Fig. 3), le cylindre tramé 13 est positionné contre le cylindre applicateur 11, pour le recouvrir avec la substance d'enduction. La chambre à racle 16 est en position plaquée contre le cylindre tramé 13 pour l'approvisionner avec la substance, d'enduction. Le système de récupération 18, avec porte-racle 21, racle 19 et moyens d'aspiration 22, est en position active, la racle 19 raclant la surface de la couche homogène du matériau poreux 12. Le système de nettoyage 24, avec le rouleau manchonné 26 et le dispositif d'arrosage 27, peut rester écarté du cylindre applicateur 11.In a production position ( Fig. 3 ), the screened cylinder 13 is positioned against the applicator cylinder 11, to cover it with the coating substance.
