DAS LEDER, vol. 27, no. 9, September 1976, pages 142-151, Darmstadt, DE; L. TORK et al: "Moderne Lederzurichtungen unter Berücksichtigung der verschiedenen Anforderungen an das Leder"
there has been described an installation for finishing pieces of leather, comprising a continuous printing machine.

Conformément au document GB-A-2031000, on a décrit un produit de finissage du cuir, consistant en un composé photopolymérisable sous UV, constitué par 40 à 90% en poids d'un prépolymère d'acrylates ou de méthacrylates et de styrène, et par 10 à 60% en poids d'uréthanes-acrylates. Ce composé photopolymérisable peut ne contenir aucun solvant.In accordance with document GB-A-2031000, a leather finishing product has been described, consisting of a photopolymerizable compound under UV, consisting of 40 to 90% by weight of a prepolymer of acrylates or methacrylates and styrene, and by 10 to 60% by weight of urethanes-acrylates. This photopolymerizable compound may not contain any solvent.

La présente invention a pour objet une installation de finissage en continu avec un produit photopolymérisable, permettant d'appliquer ce dernier en au moins deux fois, sans manipulation ou stockage intermédiaire.The subject of the present invention is a continuous finishing installation with a photopolymerizable product, making it possible to apply the latter in at least two times, without manipulation or intermediate storage.

Une installation conforme à la présente invention est caractérisée en ce qu'elle comprend au moins deux modules disposés parallèlement l'un à l'autre, comportant chacun une machine d'impression en continu, un four à rayonnement ultra-violet, et une machine de satinage et de grainage, ces différentes machines étant disposées de façon à réaliser un transport continu des pièces d'une machine à l'autre, et en ce qu'un convoyeur en forme de demi-cercle relie la machine de satinage ou grainage du premier module à la machine d'impression du second module.An installation according to the present invention is characterized in that it comprises at least two modules arranged parallel to each other, each comprising a continuous printing machine, an oven with ultraviolet radiation, and a machine of satin finishing and graining, these different machines being arranged so as to carry out a continuous transport of the parts from one machine to another, and in that a conveyor in the shape of a semicircle connects the satin finishing machine or graining of the first module to the printing machine of the second module.

Une installation selon l'invention apporte les avantages essentiels suivants.An installation according to the invention provides the following essential advantages.

Elle permet de traiter avec la souplesse voulue des séries différentes quant à la couleur, les produits de finissage utilisés, etc...It makes it possible to deal with the desired flexibility with different series as to color, the finishing products used, etc.

Elle permet aussi de raccourcir la durée du finissage, tout en préservant la qualité de ce dernier.It also makes it possible to shorten the duration of finishing, while preserving the quality of the latter.

Enfin, elle permet de traiter tous matériaux souples déformables, tels que tissus, non tissés, papiers, syndermes (enduits ou non), et cuirs, déjà prédécoupés, immédiatement avant la fabrication de la chaussure, du vêtement ou des articles destinés à la maroquinerie, l'ameublement et l'automobile, entre autres.Finally, it makes it possible to process all flexible deformable materials, such as fabrics, nonwovens, papers, synderms (coated or not), and leathers, already precut, immediately before the manufacture of the shoe, clothing or articles intended for leather goods , furniture and automotive, among others.

L'installation selon l'invention sera bien comprise, et d'autres caractéristiques de cette dernière seront mises en évidence à l'aide de la description qui suit, en référence au dessin schématique annexé, illustrant à titre d'exemples non limitatifs plusieurs formes de réalisation de cette installation.The installation according to the invention will be well understood, and other characteristics of the latter will be highlighted with the aid of the description which follows, with reference to the attached schematic drawing, illustrating by way of nonlimiting examples several forms of this installation.

Figure 1 est un schéma de l'installation selon une première forme de réalisation. Les deux modules sont montrés avant d'être disposés parallèlement l'un à l'autre.Figure 1 is a diagram of the installation according to a first embodiment. The two modules are shown before being arranged parallel to each other.

Figure 2 est un schéma de l'installation selon une seconde forme de réalisation.Figure 2 is a diagram of the installation according to a second embodiment.

Figure 3 est un schéma du principe de fonctionnement en direct de la machine d'impression.Figure 3 is a diagram of the principle of direct operation of the printing machine.

Figure 4 est un schéma du principe de fonctionnement en inverse de la machine d'impression.Figure 4 is a diagram of the reverse operating principle of the printing machine.

Ainsi que le montre la figure 1, l'installation de finissage selon l'invention comprend une succession de machines disposées en modules, en l'occurence deux modules, 1 et 2, les unes à la suite des autres. Les modules, en exercice, seront disposés parallèlement l'un à l'autre et seront reliés par un convoyeur en forme de demi-cercle qui relie la machine de satinage ou grainage du premier module à la machine d'impression du second module.As shown in Figure 1, the finishing installation according to the invention comprises a succession of machines arranged in modules, in this case two modules, 1 and 2, one after the other. The modules, in exercise, will be arranged parallel to each other and will be connected by a conveyor in the shape of a semicircle which connects the satin-finishing or graining machine of the first module to the printing machine of the second module.

Chacun des modules 1 et 2 comprend une machine d'impression 11, 21, permettant d'appliquer le produit de finissage, un four à rayonnement ultra-violet 12, 22 permettant de polymériser le produit de finissage et une machine de satinage ou grainage 13, 23 destinée à l'obtention de l'état de surface désiré.Each of the modules 1 and 2 comprises a printing machine 11, 21, making it possible to apply the finishing product, an ultraviolet radiation oven 12, 22 making it possible to polymerize the finishing product and a satin-finishing or graining machine 13 , 23 intended to obtain the desired surface finish.

Bien entendu le nombre de modules est fonction du nombre de couches de produit de finition devant être appliquées et peut être augmenté ou diminué par rapport à celui indiqué dans le présent exemple.Of course the number of modules is a function of the number of layers of finishing product to be applied and can be increased or decreased compared to that indicated in the present example.

Ainsi que le montrent notamment les figures 3 et 4, chaque machine d'impression 11, 21 est une machine dite de type mille points.As shown in particular in FIGS. 3 and 4, each printing machine 11, 21 is a so-called thousand point type machine.

Elle est constituée de deux cylindres 14, 15 d'axes horizontaux disposés l'un au-dessus de l'autre. Le cylindre supérieur 14 est un cylindre gravé comprenant une multitude d'alvéoles 14a destinées à recevoir le produit de finissage 16.It consists of two cylinders 14, 15 with horizontal axes arranged one above the other. The upper cylinder 14 is an engraved cylinder comprising a multitude of cells 14a intended to receive the finishing product 16.

Une racle 17 s'étendant parallèlement à l'axe du cylindre 14 dans la partie supérieure de celui-ci permet d'appliquer sur la surface de celui-ci la quantité désirée de produit de finissage 16.A doctor blade 17 extending parallel to the axis of the cylinder 14 in the upper part of the latter makes it possible to apply to the surface of the latter the desired quantity of finishing product 16.

Un tapis transporteur 19 passe entre les deux cylindres 14 et 15 et amène entre ceux-ci la pièce de cuir ou peau 18 devant être revêtue de la couche de finition.A conveyor belt 19 passes between the two cylinders 14 and 15 and brings between them the piece of leather or skin 18 to be coated with the finishing layer.

Les deux cylindres 14, 15 peuvent tourner en sens inverse l'un de l'autre comme indiqué par les flèches 14b et 15b, comme montré à la figure 3, le cylindre supérieur 14 tournant dans le sens inverse du sens de déplacement 19b du tapis transporteur 19.The two cylinders 14, 15 can rotate in opposite directions to one another as indicated by the arrows 14b and 15b, as shown in FIG. 3, the upper cylinder 14 rotating in the opposite direction to the direction of movement 19b of the belt carrier 19.

De ce fait, la quantité de produit de finissage 16 déposée sur les pièces de cuir ou de peau 18 est liée à la taille des alvéoles 14a du cylindre 14 ainsi qu'à la vitesse de rotation du cylindre 14.Therefore, the quantity of finishing product 16 deposited on the pieces of leather or skin 18 is related to the size of the cells 14a of the cylinder 14 as well as to the speed of rotation of the cylinder 14.

Dans ce cas, le dépôt de produit de finissage 16 sera donc d'autant plus important que le cylindre 14 tournera plus vite.In this case, the deposit of finishing product 16 will therefore be all the more important as the cylinder 14 will rotate faster.

Les deux cylindres 14, 15 peuvent également tourner dans le même sens comme indiqué par les flèches 20 (cf fig. 4), ce sens étant le même que le sens de déplacement 19b du tapis transporteur 19.The two cylinders 14, 15 can also rotate in the same direction as indicated by the arrows 20 (see fig. 4), this direction being the same as the direction of movement 19b of the conveyor belt 19.

Dans ce cas, la quantité de produit de finissage déposée est simplement proportionnelle à la dimension des alvéoles 14a.In this case, the quantity of finishing product deposited is simply proportional to the size of the cells 14a.

On notera que les cylindres 14, 15 permettent l'application d'une couche uniforme 16a de produit de finissage sur les pièces de cuir ou de peau 18.It will be noted that the cylinders 14, 15 allow the application of a uniform layer 16a of finishing product on the pieces of leather or skin 18.

Le produit de finissage 16 est un liquide comprenant de 90 à 100% de matières actives photopolymérisables sous rayonnement ultra-violet. Ce produit comprend des prépolymères insaturés, et des monomères liquides auxquels sont ajoutés des photo-initiateurs.Finishing product 16 is a liquid comprising from 90 to 100% of active materials photopolymerizable under ultraviolet radiation. This product includes unsaturated prepolymers, and liquid monomers to which photo-initiators are added.

Les prépolymères sont constitués par des uréthanes acrylates di-ou-tri-fonctionnels comportant des insaturations acryliques et se présentant sous forme de liquides de faible masse molaire. Ils peuvent comprendre également des polyesters acrylates.The prepolymers are constituted by di-or tri-functional acrylate urethanes comprising acrylic unsaturations and being in the form of liquids of low molar mass. They may also include polyesters acrylates.

Les monomères liquides sont choisis parmi les composés suivants:

  • N-Vinylpyrolidone
  • Isobornyl acrylate
  • Dioctylphtalate
  • Tertiobutylcyclohexane acrylate
  • Octyldecylacrylate
  • Ethyltriglycol acrylate.
The liquid monomers are chosen from the following compounds:
  • N-Vinylpyrolidone
  • Isobornyl acrylate
  • Dioctylphthalate
  • Tertiobutylcyclohexane acrylate
  • Octyldecylacrylate
  • Ethyltriglycol acrylate.

Les photo-initiateurs sont de préférence des cétones aromatiques pouvant être associés à des amines tertiaires en tant que co-initiateurs. On utilise de préférence un mélange de diéthyléthioxantone/diméthylaminobenzoate.The photo-initiators are preferably aromatic ketones which can be combined with tertiary amines as co-initiators. Preferably a mixture of diethylethioxantone / dimethylaminobenzoate is used.

Le produit de finissage peut également comprendre des matières colorantes pouvant être constituées par des:

  • pigments minéraux, noir de carbone,
  • pigments organiques,
  • colorants métallifères.
The finishing product may also include coloring materials which may consist of:
  • mineral pigments, carbon black,
  • organic pigments,
  • metalliferous dyes.

Ces formulations peuvent également contenir de 0 à 5% de solvants organiques, destinés à régler la viscosité de produit de finissage 16 et à faciliter l'application de celui-ci.These formulations can also contain from 0 to 5% of organic solvents, intended to regulate the viscosity of finishing product 16 and to facilitate the application thereof.

A titre d'exemple non limitatif, on peut mentionner une formulation du produit de finissage conforme à l'invention.By way of nonlimiting example, mention may be made of a formulation of the finishing product in accordance with the invention.

Pour 100 g de formulation incolore, on a:

Figure imgb0001
For 100 g of colorless formulation, we have:
Figure imgb0001

Les photo-initiateurs utilisés sont constitués par un mélange Diethylethioxantone/Diméthyl-aminobenzoate (DETX/DMBI) (11) dissous à raison de 4 à 8% en poids dans les monomères liquides de N-Vinylpyrolidone.The photo-initiators used consist of a mixture of Diethylethioxantone / Dimethyl-aminobenzoate (DETX / DMBI) (11) dissolved in an amount of 4 to 8% by weight in the liquid monomers of N-Vinylpyrolidone.

La viscosité du produit de finissage est réglée entre 0,2 et 5 pascals/secondes par l'intermédiaire du mélange N-Vinylpyrolidone/Isobornyl-acrylate.The viscosity of the finishing product is adjusted between 0.2 and 5 pascals / seconds by means of the N-Vinylpyrolidone / Isobornyl-acrylate mixture.

Si le produit de finissage est coloré, le pourcentage de pigments par rapport à la formulation incolore est variable et dépend de la couverture recherchée et de la nature du pigment qui peut être plus ou moins absorbante du rayonnement U.V. Ceci influe donc également sur le pourcentage de photo-initiateurs intégrés à la formulation.If the finishing product is colored, the percentage of pigments compared to the colorless formulation is variable and depends on the desired coverage and the nature of the pigment which can be more or less absorbent of UV radiation This therefore also influences the percentage of photo-initiators integrated into the formulation.

Lors du passage dans le four à rayonnement ultra-violet 12, 22, les photo-initiateurs provoquent la réticulation des monomères et des pré-polymères de façon à donner des polymères finaux.During the passage through the ultraviolet radiation oven 12, 22, the photoinitiators cause the crosslinking of the monomers and of the pre-polymers so as to give final polymers.

On notera que cette polymérisation du produit s'effectue quasiment instantanément.It will be noted that this polymerization of the product takes place almost instantaneously.

Le monomères jouent dans ce cas le rôle de diluants des pré-polymères mais du fait de leur réactivité, ils sont intégrés au film de polymères se produisant et il n'y a donc pas d'évaporation de produit mis à part celle de 0 à 5% de solvants organiques éventuellement contenus dans le produit de finissage.The monomers in this case play the role of diluents of the pre-polymers but because of their reactivity, they are integrated into the film of polymers occurring and there is therefore no evaporation of product apart from that of 0 to 5% of organic solvents possibly contained in the finishing product.

On comprend donc bien que dans ce cas, plus aucune opération de sèchage n'est donc nécessaire et qu'à la sortie du premier four 12 une seconde couche de produit de finissage peut être immédiatement appliquée dans le second module 2 de l'installation. Les fours de rayonnements ultra-violets 12, 22 sont des fours de type classique.It is therefore clear that in this case, no more drying operation is therefore necessary and that at the outlet of the first oven 12 a second layer of finishing product can be immediately applied in the second module 2 of the installation. The ultra-violet radiation ovens 12, 22 are conventional type ovens.

Ils comprennent chacun un convoyeur 25 en matériau inoxydable traversant ce four de part en part.They each include a conveyor 25 made of stainless material passing through this furnace right through.

Ces convoyeurs sont surmontés de façon connue en soi de lampes focalisantes (non représentées sur le dessin) et émettant un rayonnement ultra-violet de fréquence comprise entre 150 et 700 mm.These conveyors are surmounted in a manner known per se of focusing lamps (not shown in the drawing) and emitting ultra-violet radiation of frequency between 150 and 700 mm.

A la suite de chaque four 12, 22 est disposée une machine de satinage ou grainage 13, 23 dont le but est soit d'augmenter le brillant de la couche de finition (c'est l'opération de satinage), soit d'imprimer sur cette couche de finition un relief déterminé (opération de grainage). Chacune de ces machines est constituée de deux cylindres, l'un supérieur 26 dit de travail et l'entre inférieur 27, et d'axes respectivement 26a et 27a horizontaux. Le cylindre de travail 26 est chauffé entre 60 et 160°C et appuie sur les pièces 18 avec une pression réglable.Following each oven 12, 22 is arranged a satin-finishing or graining machine 13, 23 the purpose of which is either to increase the gloss of the finishing layer (this is the satin-finishing operation), or to print on this finishing layer a determined relief (graining operation). Each of these machines is made up of two cylinders, the upper one called work 26 and the lower entry 27, and horizontal axes 26a and 27a respectively. The working cylinder 26 is heated between 60 and 160 ° C and presses on the parts 18 with an adjustable pressure.

Celles-ci sont amenées par un tapis transporteur 28 sans fin qui traverse la machine et passe entre les deux cylindres 26, 27.These are brought by an endless conveyor belt 28 which passes through the machine and passes between the two cylinders 26, 27.

Le cylindre de travail 26 a une surface lisse dans le cas où l'on désire réaliser une opération de satinage et a une surface grainée pour réaliser une opération de grainage.The working cylinder 26 has a smooth surface in the case where it is desired to carry out a satin-finishing operation and has a grained surface to carry out a graining operation.

La machine de satinage ou de grainage est conçue de façon à permettre un changement facile du cylindre 26. Ainsi que le montre la fig. 1, les cylindres 26 et 27 tournent en sens inverse (flèches 26b et 27b), le cylindre de travail tournant dans le même sens que le tapis transporteur 28 (flèche 28b).The satin-finishing or graining machine is designed so as to allow an easy change of the cylinder 26. As shown in FIG. 1, the cylinders 26 and 27 rotate in opposite directions (arrows 26b and 27b), the working cylinder rotating in the same direction as the conveyor belt 28 (arrow 28b).

Ainsi que l'on le concevra aisément, l'installation de finissage selon l'invention permet d'obtenir au moyen d'un seul passage dans les différents modules 1 et 2 de celle-ci, la couche de finissage désirée et sans nécessité de sèchage ultérieur. Dans le cas de cuir pleine fleur, le dépôt par passage est environ de 10 à 15 g/m2 et la vitesse de passage est comprise entre 5 à 10 mètres/minute.As will be easily understood, the finishing installation according to the invention makes it possible to obtain, by means of a single passage in the various modules 1 and 2 thereof, the desired finishing layer and without the need to subsequent drying. In the case of full grain leather, the deposit per pass is approximately 10 to 15 g / m2 and the speed of passage is between 5 to 10 meters / minute.

On peut noter que la couche de finissage appliquée, bien que généralement colorée, peut être également incolore.It should be noted that the finishing layer applied, although generally colored, may also be colorless.

Le nombre de couches de finissage appliquées dépend bien entendu de l'aspect de finissage souhaité.The number of finishing coats applied depends of course on the desired finishing appearance.

Cependant, avec une machine d'impression permettant, par passage à une vitesse d'environ 10 m/mn, un dépôt compris entre 10 et 25 g/m2, ce nombre de couches ne devra pas excéder trois, pour obtenir un film uniforme sec, de façon que pour des raisons pratiques, les pièces de cuirs ne deviennent pas rigides et soient facilement manipulables et empilables.However, with a printing machine allowing, by passing at a speed of about 10 m / min, a deposit of between 10 and 25 g / m2, this number of layers should not exceed three, to obtain a uniform dry film , so that for practical reasons, the pieces leathers do not become rigid and are easy to handle and stack.

On notera également que la viscosité de la formulation pigmentée est comprise entre 0,2 et 5 pascals-secondes.It will also be noted that the viscosity of the pigmented formulation is between 0.2 and 5 pascals-seconds.

Enfin, les cuirs obtenus, sous forme de pièces prédécoupées par le présent procédé, doivent à titre d'illustration, répondre aux caractéristiques suivantes:

  • bonne tenue au flexomètre BALLY: pas de fendillement visible, ni de décollement du film après:
    • · 20 000 flexions en humide
    • · 100 000 flexions à sec.
  • bonne tenue aux frottements VESLIC: pas ou peu de dégorgement sur le feutre et pas d'élimination du film par décollement après:
    • · 100 va et vient en humide
    • · 200 va et vient à sec.
Finally, the leathers obtained, in the form of parts precut by the present process, must by way of illustration, meet the following characteristics:
  • good resistance to the BALLY flexometer: no visible cracking, no peeling of the film after:
    • 20,000 bends in wet
    • 100,000 dry bends.
  • good resistance to friction VESLIC: no or little disgorgement on the felt and no elimination of the film by peeling after:
    • · 100 back and forth wet
    • · 200 comes and goes dry.

L'obtention de ces deux caractéristiques essentielles ne devra pas l'être au détriment de l'aspect: uniformité de brillant et de couverture et toucher lisse et sec.Obtaining these two essential characteristics should not be to the detriment of the appearance: uniformity of gloss and coverage and smooth, dry feel.

La figure 2 montre un autre exemple de réalisation de l'invention dans laquelle les deux modules 101, 102 sont déjà disposés parallèlement l'un à l'autre.FIG. 2 shows another embodiment of the invention in which the two modules 101, 102 are already arranged parallel to one another.

Dans cette installation, de même que dans l'installation précédemment décrite, chaque module 101, 102 est constitué respectivement d'une machine d'impression 111, 121, d'un four 115 et d'une machine de satinage ou grainage 113, 123. Le seule différence par rapport à l'installation de la figure 1 réside dans le fait que le four 115 s'étend à la fois sur les deux modules 101 et 102, les autres machines 111, 113, 121, 123 étant identiques aux machines 11, 13, 21 et 23 décrites précédemment.In this installation, as in the installation previously described, each module 101, 102 consists respectively of a printing machine 111, 121, an oven 115 and a satin-finishing or graining machine 113, 123 The only difference compared to the installation of FIG. 1 is that the oven 115 extends at the same time on the two modules 101 and 102, the other machines 111, 113, 121, 123 being identical to the machines 11, 13, 21 and 23 described above.

Cette disposition permet de n'avoir qu'un seul four 115 pour deux modules successifs et est donc particulièrement avantageuse.This arrangement makes it possible to have only one oven 115 for two successive modules and is therefore particularly advantageous.

Comme dans le cas de l'installation de la figure 1, la machine de satinage ou de grainage 113 du premier module 101 est reliée à la machine d'impression 121 du second module 102 par un convoyeur 130 en forme de demi-cercle apte à faire effectuer un demi-tour aux pièces sortant du premier module et entrant dans le second module.As in the case of the installation in FIG. 1, the satin-finishing or graining machine 113 of the first module 101 is connected to the printing machine 121 of the second module 102 by a conveyor 130 in the form of a semicircle capable of have the parts leaving the first module and entering the second module turn around.

Bien entendu, les différents tapis transporteurs 19, 25 et 28 des différentes machines de chaque module sont conçus de façon à réaliser un transport continu de chaque pièce de cuir ou de peau 18 devant être traitée depuis l'entrée de l'installation jusqu'à la sortie de celle-ci.Of course, the different conveyor belts 19, 25 and 28 different machines of each module are designed so as to carry out a continuous transport of each piece of leather or skin 18 to be treated from the entry of the installation to the exit of the latter.

En outre, un système de régulation ou d'accouplement entre ces différents tapis peut être prévu de façon à convoyer les pièces à la même vitesse.In addition, a regulation or coupling system between these different belts can be provided so as to convey the pieces at the same speed.

On notera que cette disposition permet d'avoir une alimentation et une évacuation de l'installation entièrement automatique.It will be noted that this arrangement makes it possible to have a fully automatic supply and evacuation of the installation.

Conformément à une variante avantageuse de l'invention, l'installation de finissage comprend un poste de teinture par imprégnation classique non représenté sur le dessin et disposé et continu avant la machine d'impression en continu (11, 111) située en tête de l'installation.According to an advantageous variant of the invention, the finishing installation comprises a conventional impregnation dyeing station not shown in the drawing and arranged and continuous before the continuous printing machine (11, 111) located at the head of the 'installation.

Cette disposition permet de compléter l'installation et de produire des matériaux souples finis possédant de plus une coloration stable et de qualité.This arrangement makes it possible to complete the installation and to produce finished flexible materials which moreover have a stable and quality coloring.

Dans le cas d'un cuir effleuré, c'est-à-dire, poncé et imprégné classiquement dans le poste de teinture, deux à trois applications d'une couche de finissage avec réticulation après chaque passage sont nécessaires. Le dépôt de produit de finissage par passage est de l'ordre de 20 à 25 g/m2.In the case of a lightly touched leather, that is to say, sanded and impregnated conventionally in the dyeing station, two to three applications of a finishing layer with crosslinking after each pass are necessary. The deposit of finishing product per pass is of the order of 20 to 25 g / m2.

L'installation selon l'invention est particulièrement adaptée au traitement de matériaux souples et en particulier de peaux déjà découpées puisqu'il n'implique aucune manipulation de celles-ci. Elle peut, bien entendu, être également appliquée à des pièces entières.The installation according to the invention is particularly suitable for the treatment of flexible materials and in particular of skins already cut since it does not involve any manipulation thereof. It can, of course, also be applied to whole parts.

L'installation selon l'invention est donc particulièrement adaptée au traitement de matériaux souples et en particulier de pièces de cuir au sein même de l'entreprise de fabrication de chaussures ou similaire et elle permet donc une adaptation rapide aux tendances variables du marché.The installation according to the invention is therefore particularly suitable for the treatment of flexible materials and in particular leather pieces within the shoe manufacturing or similar company and it therefore allows rapid adaptation to variable market trends.

Bien entendu; dans ce cas, des systèmes seront prévus pour permettre un nettoyage rapide des machines d'impression ainsi qu'un changement rapide du produit de finissage utilisé.Of course; in this case, systems will be provided to allow rapid cleaning of the printing machines as well as a rapid change of the finishing product used.

Si nécessaire, un système d'aspiration ou de dépression pourra être prévu au niveau de chaque tapis transporteur pour maintenir les pièces.If necessary, a suction or vacuum system can be provided at each conveyor belt to hold the parts.

Si nécessaire également, un système de type racle pourra être prévu au niveau des rouleaux d'impression et de satinage afin d'empêcher l'adhérence sur ceux-ci des pièces traitées.If necessary also, a doctor blade type system can be provided at the level of the printing and satin-brushing rollers in order to prevent the adhesion to the treated parts.
