Description

La présente invention concerne le domaine du papier à usage sanitaire ou domestique. Elle vise un rouleau de papier comportant une gorge annulaire et son procédé de fabrication.The present invention relates to the field of paper for sanitary or domestic use. It relates to a paper roll having an annular groove and its method of manufacture.

Dans ce domaine, l'invention vise en particulier le papier hygiénique, le papier d'essuyage utilisé notamment comme essuie-tout ou essuie- main. Ces papiers sont présentés à l'utilisateur par exemple sous la forme de rouleaux constitués d'une feuille , éventuellement prédécoupée en coupons, enroulée autour d'un axe central. Les rouleaux peuvent être de type avec ou sans mandrin et dans ce dernier cas, avec ou sans orifice central. Pour rendre leur utilisation commode les rouleaux sont généralement placés dans un support adapté.In this field, the invention is particularly toilet paper, wiping paper used especially as a paper towel or towel. These papers are presented to the user for example in the form of rolls consisting of a sheet, possibly pre-cut into coupons, wound around a central axis. The rollers may be of type with or without mandrel and in the latter case, with or without central opening. To make their use convenient the rollers are usually placed in a suitable holder.

Lorsque la destination de l'usage dépasse le cercle domestique, dans les établissements collectifs en particulier tels que les hôtels, les restaurants, les hôpitaux ou autres, les distributeurs sont élaborés pour assurer une pluralité de fonctions. Il s'agit du stockage du papier, le maintien de l'hygiène du produit, le contrôle de la consommation du papier ou encore d'éviter l'emploi de rouleaux non conformes.When the destination of the use goes beyond the domestic circle, in the collective establishments in particular such as hotels, restaurants, hospitals or other, the distributors are elaborated to ensure a plurality of functions. It involves storing paper, maintaining product hygiene, controlling paper consumption or avoiding the use of non-compliant rolls.

Pour ce dernier cas et assurer à la fois un guidage continu tout au long de la consommation du rouleau et une distribution satisfaisante de la feuille, lorsque le rouleau est à mandrin notamment, on a proposé des systèmes qui comprennent des pièces en saillie par rapport à l'une des faces latérales du support de rouleau. Ces pièces sont annulaires ou excentrées par rapport à l'axe du rouleau et coopèrent avec une rainure de forme complémentaire ménagée sur la face latérale adjacente du rouleau.For the latter case and to ensure both a continuous guidance throughout the consumption of the roll and a satisfactory distribution of the sheet, when the mandrel roller is particular, it has been proposed systems which comprise parts protruding from one of the side faces of the roll holder. These parts are annular or eccentric with respect to the axis of the roller and cooperate with a groove of complementary shape formed on the adjacent side face of the roller.

Pour réaliser cette gorge sur le rouleau, un moyen connu consiste à découper la feuille convenablement pendant qu'elle est enroulée autour de l'axe du rouleau ou bien d'un mandrin. Le brevet EP 380 438 décrit une méthode avec découpe d'une feuille de large laize en plusieurs feuilles de largeur plus faible correspondant à celle des rouleaux à fabriquer. On utilise une pluralité de lames parallèles entre elles qui assurent une découpe en continu de la feuille large. Des lames escamotables assurent la découpe de bandes supplémentaires de largeur correspondant à la profondeur de la gorge sur une longueur déterminée en fonction de la largeur de gorge à former.To achieve this groove on the roll, a known means is to cut the sheet properly as it is wound around the axis of the roller or a mandrel. The patent EP 380,438 describes a method of cutting a sheet of large width into several sheets of smaller width corresponding to that of the rolls to be manufactured. A plurality of blades parallel to each other are used which ensure continuous cutting of the wide sheet. Retractable blades cut additional strips of width corresponding to the depth of the groove over a length determined according to the groove width to be formed.

Selon un autre moyen connu, on découpe après formation du rouleau la gorge au moyen d'un outil de coupe. On constate que tous les procédés connus sont limités à une solution où la gorge est obtenue par enlèvement de matière.According to another known means, the groove is cut after formation of the roller by means of a cutting tool. It is found that all the processes known are limited to a solution where the groove is obtained by removal of material.

Le déposant a cherché à améliorer la technique de formation de la gorge. Un objectif a été la mise au point d'une méthode plus simple à mettre en oeuvre que la découpe de la bande de matière pendant son enroulement. Cette dernière méthode est en effet pénalisante lorsqu'il s'agit de fabriquer des produits à une cadence élevée comme cela est requis sur les machines de production moderne.The applicant has sought to improve the technique of throat formation. One objective has been the development of a simpler method to implement than the cutting of the strip of material during its winding. The latter method is indeed penalizing when it comes to manufacturing products at a high rate as is required on modern production machines.

Le déposant a aussi cherché à améliorer la qualité du produit. Même si la gorge est de profondeur raisonnable, il en résulte un manque de matière sur les coupons au droit de la gorge.The applicant has also sought to improve the quality of the product. Even if the throat is of reasonable depth, it results in a lack of material on the coupons right of the throat.

Conformément à l'invention, le procédé de fabrication d'un rouleau de papier absorbant á usage sanitaire ou domestique, le rouleau présentant un orifice central et comprenant une feuille continue enrolée autour d'un axe et formant des spires hélicoïdales, selon lequel après avoir formé le roleau on déforme au moins un des flancs du rouleau par compression au moyen d'un outil comprenant une nervure, la nervure formant une gorge sur au moins un des flancs du rouleau, la gorge définissant un contour fermé autour de cet axe, est caractérisé par le fait que l'outil comprend un bossage central cylindrique de diamètre correspondant à celui de l'orifice central, qui permet d'assurer un bon guidage du rouleau avant la phase de déformation, la largeur de la feuille formant les spires au droit de la gorge etant réduite par déformation et/ou par compression parallèlement à l'axe.According to the invention, the method of manufacturing a roll of absorbent paper for sanitary or domestic use, the roll having a central orifice and comprising a continuous sheet enrolée about an axis and forming helical turns, according to which after having formed the roll is deformed at least one of the sides of the roll by compression by means of a tool comprising a rib, the rib forming a groove on at least one of the sides of the roll, the groove defining a closed contour around this axis, is characterized in that the tool comprises a cylindrical central boss of diameter corresponding to that of the central orifice, which ensures a good guide of the roll before the deformation phase, the width of the sheet forming the turns to the right of the groove being reduced by deformation and / or compression parallel to the axis.

La réduction par déformation permet, au moment où l'on déroule la feuille au niveau de la gorge de retrouver, par déploiement, la quasi intégralité de la largeur. Cela est possible parce que le papier à usage sanitaire ou domestique est un papier absorbant, la ouate de cellulose, de faible grammage, dont la caractéristique est d'être très souple.The reduction by deformation makes it possible, when the sheet is unfolded at the level of the groove, to find, by deployment, almost the entire width. This is possible because the paper for sanitary or domestic use is an absorbent paper, cellulose wadding, light weight, whose characteristic is to be very flexible.

Un avantage qui découle du précédent est d'autoriser une gorge plus profonde. Une saillie de plus grande hauteur coopérant avec une gorge plus profonde assure un guidage plus efficace.An advantage that stems from the previous one is to allow a deeper throat. A projection of greater height cooperating with a deeper groove provides a more efficient guidance.

Un autre avantage est de permettre des formes de gorge variée, polygonale par exemple ou simplement circulaire.Another advantage is to allow shapes of varied throat, polygonal for example or simply circular.

De préférence la gorge est à section transversale en U avec deux bords parallèles entre eux et plus particulièrement le fond de la gorge est incurvé.Preferably the groove is U-shaped cross section with two mutually parallel edges and more particularly the bottom of the groove is curved.

Le déposant connaît le brevet US 3.038.598 qui mentionne la formation d'une gorge à section en V par compression. Il est à noter qu'un déplacement axial d'un poinçon à section en V dont les branches sont inclinées par rapport à cette direction conduit à un écrasement latéral des spires. Cela est possible parce que le papier absorbant est souple et de faible densité. Toutefois la tenue dans le temps d'une telle forme n'est pas garantie car le papier en raison de son élasticité a tendance à reprendre sa forme initiale. En outre le guidage n'est pas satisfaisant comparativement à une gorge à section en U.The applicant knows the US Patent 3,038,598 which mentions the formation of a compression V-section groove. It should be noted that an axial displacement of a V-section punch whose branches are inclined relative to this direction leads to a lateral crushing of the turns. This is possible because the absorbent paper is soft and of low density. However the holding in time of such a form is not guaranteed because the paper because of its elasticity tends to take its shape initial. In addition, the guidance is not satisfactory compared to a U-section groove.

La présente invention s'applique à tout type de rouleau de papier absorbant avec un trou central et dans ce cas de préférence avec un mandrin cylindrique.The present invention applies to any type of absorbent paper roll with a central hole and in this case preferably with a cylindrical mandrel.

D'autres caractéristiques et avantages ressortiront de la description qui suit d'un mode de réalisation non limitatif en référence aux dessins sur lesquels :

  • La figure 1 montre un rouleau avec gorge en perspective,
  • La figure 2 montre une coupe selon la direction II-II de la figure 1,
  • La figure 3 montre l'outil avec lequel on forme la gorge,
  • La figure 4 montre une variante d'outil,
  • La figure 5 montre la mise en place de l'outil et la formation de la gorge,
  • La figure 6 montre, en coupe, le rouleau de l'invention en place dans un distributeur avec des moyens supports adaptés.
Other features and advantages will emerge from the following description of a non-limiting embodiment with reference to the drawings in which:
  • The figure 1 shows a scroll with a perspective groove,
  • The figure 2 shows a section along the II-II direction of the figure 1 ,
  • The figure 3 shows the tool with which the groove is formed,
  • The figure 4 shows a variant of a tool,
  • The figure 5 shows the placement of the tool and the formation of the throat,
  • The figure 6 shows, in section, the roll of the invention in place in a dispenser with suitable support means.

Le rouleau représenté sur la figure 1 est un rouleau 1 par exemple de papier hygiénique avec un orifice central 3. La feuille continue est enroulée autour d'un mandrin en carton 5. Le papier absorbant est de la ouate de cellulose mono-pli ou multi-plis, généralement de grammage compris entre 15 et 40 g/m2 par pli. L'invention intéresse plutôt l'utilisation en collectivité avec des rouleaux de plus grande dimension que l'utilisation domestique.The roll represented on the figure 1 is a roll 1 for example toilet paper with a central orifice 3. The continuous sheet is wrapped around a cardboard mandrel 5. The absorbent paper is cellulose wadding single-ply or multi-ply, generally grammage included between 15 and 40 g / m 2 per fold. The invention rather concerns the use in community with rollers of larger size than the domestic use.

Le rouleau comprend sur au moins une face une gorge circulaire à proximité du trou central 3. On a représenté sur la figure 2 le détail du rouleau vu en coupe axiale au niveau de la gorge. On voit l'orifice central 3 à l'intérieur du mandrin 5 et les spires hélicoïdales 8 de la feuille qui a été enroulée autour du mandrin. Depuis le mandrin l'enroulement comprend un certain nombre n1 de spires de feuille de même largeur que le rouleau. Ensuite un nombre n2 de spires a une largeur inférieure à celle du rouleau. Ces n2 spires définissent la gorge 7 sur le flanc du rouleau. La feuille constituant ces n2 spires est déformée par compression parallèlement à l'axe XX du rouleau. Elle forme des plis 8' sur une faible distance au droit de la gorge 7. En raison de la faible densité du papier absorbant et dans la mesure où le serrage de l'enroulement le permet les n2 spires sont déformées individuellement et les plis de la zone plissée ne sont pas imbriqués les uns dans les autres.The roller comprises on at least one face a circular groove near the central hole 3. It is represented on the figure 2 the detail of the roll seen in axial section at the throat. We see the central orifice 3 inside the mandrel 5 and the helical turns 8 of the sheet which has been wound around the mandrel. Since the mandrel the winding comprises a number n1 of sheet turns of the same width as the roll. Then a number n2 of turns has a width smaller than that of the roll. These n2 turns define the groove 7 on the side of the roll. The sheet constituting these n2 turns is deformed by compression parallel to the axis XX of the roll. It forms folds 8 'over a short distance to the right of the 7. Because of the low density of the absorbent paper and to the extent that the winding clamping allows it the n2 turns are deformed individually and the folds of the folded area are not nested within each other.

Cette gorge est obtenue par pressage selon l'axe XX d'un outil tel que représenté sur la figure 3. Cet outil 10 comporte une partie centrale 12 de diamètre égal à celui de l'orifice 3 du rouleau et formant un bossage. Cette partie centrale 12 permet de garantir un bon centrage du rouleau avant la phase de déformation. La partie centrale est ici chanfreinée pour faciliter son introduction dans l'orifice 3. L'outil présente une nervure annulaire 15 de section en U avec un sommet arrondi ou aplati mais sans arête vive. La partie centrale 12 est plus haute que la partie annulaire. On forme la gorge en présentant, comme on l'a représenté sur la figure 5, l'outil avec sa partie centrale dans l'orifice 3, et en exerçant une pression axiale de manière à venir comprimer le rouleau le long de la nervure annulaire 15. Le flanc est ainsi déformé jusqu'à la profondeur voulue et au maximum sur toute la hauteur de la nervure annulaire. La feuille constituant les spires sous l'outil est déformée axialement avec formation des plis 8' que l'on voit sur la figure 2. La partie centrale 12 de l'outil 10 forme un guide pour positionner la gorge par rapport à l'axe XX.This groove is obtained by pressing along the axis XX of a tool as shown in FIG. figure 3 . This tool 10 comprises a central portion 12 of diameter equal to that of the orifice 3 of the roller and forming a boss. This central portion 12 ensures a good centering of the roll before the deformation phase. The central portion is here chamfered to facilitate its introduction into the orifice 3. The tool has an annular rib 15 of U-section with a rounded or flattened top but without sharp edge. The central portion 12 is higher than the annular portion. The throat is formed by presenting, as shown on the figure 5 , the tool with its central portion in the orifice 3, and exerting an axial pressure so as to compress the roll along the annular rib 15. The sidewall is thus deformed to the desired depth and to the maximum on the entire height of the annular rib. The sheet constituting the turns under the tool is axially deformed with formation of the folds 8 'that can be seen on the figure 2 . The central portion 12 of the tool 10 forms a guide for positioning the groove relative to the axis XX.

La forme de la gorge est libre ; elle dépend de la forme de la saillie de guidage qui a été choisie sur le support de rouleau. La figure 4 montre un autre exemple d'outil 20 avec une nervure 25 de forme polygonale autour de la partie centrale 22 qui reste circulaire. Le principe est le même que précédemment.
Dans tous les cas, on cherche à obtenir une gorge 7 définissant un contour fermé autour de l'axe XX .The shape of the throat is free; it depends on the shape of the guide projection which has been chosen on the roll support. The figure 4 shows another example of a tool 20 with a rib 25 of polygonal shape around the central portion 22 which remains circular. The principle is the same as before.
In all cases, it is sought to obtain a groove 7 defining a closed contour about the axis XX.

On voit sur la figure 6 en coupe axiale le rouleau 1 monté dans son distributeur dont on n'a représenté que la partie formant le support du rouleau. Le rouleau 1 avec son mandrin 5 et sa gorge 7 est maintenu par deux bouchons cylindriques 31 et 32 engagés dans le mandrin à ses extrémités. Ces bouchons sont mobiles en rotation autour des pivots, 41 et 42 respectivement, solidaires des parois latérales du distributeur.We see on the figure 6 in axial section the roller 1 mounted in its dispenser of which only the portion forming the support of the roll has been shown. The roller 1 with its mandrel 5 and its groove 7 is held by two cylindrical plugs 31 and 32 engaged in the mandrel at its ends. These plugs are rotatable about the pivots, 41 and 42 respectively, secured to the side walls of the dispenser.

Sur la face comportant la gorge 7, le bouchon 32 comprend une nervure annulaire 32' de rayon et de largeur adaptés pour venir se loger dans la gorge 7.On the face having the groove 7, the stopper 32 comprises an annular rib 32 'of radius and width adapted to be housed in the groove 7.
