Abstract

The roll has a flexible material sheet formed by winding the sheet around a winding axis. A central unwinding section (10B) forms a protrusion along length of the axis with respect to a part of a plane of one of sides of the roll. The unwinding section has a portion belonging to an inner end of the sheet. The unwinding section is formed by folding transversely on the axis of the roll. An independent claim is also included for a roll manufacturing method.

Description

L'invention porte sur un rouleau de papier ou autre matériau absorbant semblable tel qu'un non-tissé, destiné par exemple à l'essuyage. Elle concerne en particulier le domaine des produits à usage sanitaire ou domestique.The invention relates to a roll of paper or other similar absorbent material such as a nonwoven, for example for wiping. It concerns in particular the field of products for sanitary or domestic use.

Pour ces applications, les rouleaux sont constitués d'une feuille continue qui comporte un ou plusieurs plis, éventuellement prédécoupée en coupons consécutifs dans la direction du bobinage, et enroulée axialement, préférentiellement autour d'un axe qui peut supporter ou non un mandrin ; le rouleau peut ainsi comprendre un mandrin central ou non. La feuille peut être dévidée: soit à partir de la surface externe du rouleau dans la direction du bobinage; soit par l'intérieur, à partir du centre dans une direction perpendiculaire à celle du bobinage du rouleau. Dans ce dernier cas, on dit que le rouleau est à dévidage central.For these applications, the rollers consist of a continuous sheet which comprises one or more plies, possibly pre-cut into consecutive coupons in the direction of the winding, and wound axially, preferably around an axis which may or may not support a mandrel; the roll can thus comprise a central mandrel or not. The sheet may be unwound: either from the outer surface of the roll in the direction of the winding; either from the inside, from the center in a direction perpendicular to that of the roll winding. In the latter case, it is said that the roll is centrally rewind.

La présente invention a pour objet les rouleaux que l'on utilise en dévidage central.The present invention relates to the rollers that are used in central unwinding.

Quand le rouleau comporte un mandrin, on doit commencer par extraire celui-ci. En général, il a été conçu pour qu'on puisse le déchirer en tirant sur son bord ; le plus souvent, à l'une des extrémités de la spirale hélicoïdale en carton qui le forme. Cependant, la pratique montre que cette solution n'est pas toujours satisfaisante, car l'extraction du mandrin se révèle être parfois difficile si la ou les zones de rupture sont mal formées. De plus, cette action peut entraîner les premières feuilles du rouleau qui deviennent difficilement utilisables. En outre, les premières spires de la feuille étant le plus souvent collées au mandrin, elles sont impropres à toute utilisation et sont alors une cause de déchets.When the roll has a mandrel, we must first extract it. In general, it has been designed so that it can be torn by pulling on its edge; most often at one end of the cardboard spiral spiral that forms it. However, practice shows that this solution is not always satisfactory, because the extraction of the mandrel is sometimes difficult if the fracture zone or areas are poorly formed. In addition, this action can cause the first sheets of the roll which become difficult to use. In addition, the first turns of the sheet being most often glued to the mandrel, they are unfit for any use and are a cause of waste.

Ce mandrin est particulièrement coûteux à réaliser, puisque généralement composé de deux ou plusieurs couches de carton liées par collage. Il est associé également le plus souvent à une colle « d'accrochage » de la première spire du rouleau. Il n'est de plus d'aucune utilité une fois retiré, et devient donc un déchet.This mandrel is particularly expensive to produce, since generally consists of two or more layers of cardboard bonded by bonding. It is also associated most often with a glue "hanging" of the first turn of the roller. It is no longer useful once removed, and becomes a waste.

Pour pallier cet inconvénient, on proprose aussi des bobines à dévidage central sans mandrin. Celles-ci sont à priori de mise en oeuvre plus facile par l'utilisateur, car il n'est plus nécessaire d'enlever le mandrin préalablement à leur mise en service. Pour réaliser celles-ci, on peut, en fabrication, prévoir un mandrin provisoire sur lequel on enroule la feuille. On retire ensuite le mandrin, avant le conditionnement des bobines. Cette technique présente des contraintes sur le plan industriel car il faut ajouter un poste d'extraction des mandrins à la ligne de bobinage.To overcome this disadvantage, it also proprose coil central reeling without mandrel. These are in principle easier to implement by the user, because it is no longer necessary to remove the mandrel prior to commissioning. To achieve these, one can, in manufacture, provide a temporary mandrel on which the sheet is wound. The mandrel is then removed before conditioning the coils. This technique presents constraints on the industrial level because it is necessary to add an extraction station of the mandrels to the winding line.

Selon un mode de fabrication sans mandrin, la feuille est découpée en ligne dans le sens longitudinal, avant bobinage, à partir d'une feuille mère de grande largeur, et en autant de bandes que de rouleaux individuels à obtenir.According to a chuckless method of manufacture, the sheet is cut in line in the longitudinal direction, before winding, from a large width sheet, and in as many strips as individual rolls to obtain.

Selon un autre mode de fabrication, on enroule directement la feuille mère sur une broche, également sans interposition de mandrin. La feuille initiale qui est de grande largeur, est d'abord enroulée de manière à former une bobine unique au diamètre définitif du rouleau individuel, appelé « log » dans le domaine. Après formation du log, on l'extrait de la broche et on le tronçonne ensuite en rouleaux individuels.According to another method of manufacture, the mother sheet is wound directly on a pin, also without the interposition of a mandrel. The initial sheet, which is large in width, is first rolled up to form a single coil with the final diameter of the individual roll, called "log" in the field. After forming the log, it is extracted from the spindle and then cut into individual rolls.

Cependant, la feuille, que ce soit de l'ouate de cellulose, crêpée sec ou humide, du papier voie sèche ou un non-tissé, présente une certaine élasticité. En raison des contraintes internes du rouleau, dues par exemple au serrage de la feuille sur la broche pendant le bobinage et/ou à la tension de la feuille que génère l'opération de déroulement/enroulement par la machine, on ne peut éviter normalement la réduction du trou central par l'affaissement ou l'effondrement au centre des premières spires après que l'on a retiré la broche. Cet effondrement se produit, par exemple, après extraction de la broche et/ou au moment de la coupe du log, par la pression exercée par la scie.However, the sheet, whether cellulose wadding, creped dry or wet, dry paper or a nonwoven, has some elasticity. Due to the internal stresses of the roll, due for example to the clamping of the sheet on the spindle during the winding and / or the tension of the sheet that generates the unwinding / winding operation by the machine, it can not be avoided normally. reducing the central hole by collapsing or collapsing in the center of the first turns after the pin has been removed. This collapse occurs, for example, after extraction of the spindle and / or at the time of cutting the log, by the pressure exerted by the saw.

En tout état de cause, on constate une réduction partielle ou totale du trou central au cours des manutentions et transport, en raison des chocs et/ou vibrations inévitables auxquels les rouleaux sont soumis.In any case, there is a partial or total reduction of the central hole during handling and transport, due to shocks and / or inevitable vibrations to which the rollers are subjected.

Lorsque le trou central est complètement réduit, il est difficile de le reformer au moins à la main, et la préhension de la première spire n'est pas aisée. Il s'ensuit inévitablement des déchets, notamment pour la mise en service du rouleau dans un distributeur, car on est amené alors à saisir plusieurs spires à la fois.When the central hole is completely reduced, it is difficult to reform at least by hand, and the grip of the first turn is not easy. It inevitably follows waste, especially for the commissioning of the roller in a dispenser, because it is then necessary to grasp several turns at a time.

On sait réaliser des rouleaux sans mandrin dont le trou central reste formé après extraction de la broche et/ou après coupe par une scie. On peut utiliser par exemple une broche dont le profil, cannelé ou polygonal, permet la formation d'un trou dont les parois sont auto-portantes. Un exemple de réalisation est illustré par le brevet FR 2554799 .It is known to produce mandrelless rollers whose central hole remains formed after extraction of the spindle and / or after cutting by a saw. One can use for example a pin whose profile, grooved or polygonal, allows the formation of a hole whose walls are self-supporting. An exemplary embodiment is illustrated by the patent FR 2554799 .

Néanmoins, le trou central est de faible diamètre et les premières spires restent difficiles d'accès. Elles se présentent en une torche serrée, hélicoïdale à faible « pas », peu propice à une utilisation aisée. Si le diamètre du trou central est plus important, on peut difficilement éviter d'associer les premières spires entre elles. Pour cela on emploie un agent de liaison que l'on dépose directement sur la feuille ou indirectement via la broche ou un des cylindres de bobinage, par un système adapté, au moment de l'enroulement des premières spires sur la broche. Tout autre principe d'association entre elles des premières spires, par procédé mécanique notamment, est applicable. On consolide ainsi ces premières spires qui ensemble résistent aux efforts des contraintes internes.Nevertheless, the central hole is of small diameter and the first turns remain difficult to access. They come in a tight, helical, low "pitch" torch that is not conducive to easy use. If the diameter of the central hole is larger, it is difficult to avoid associating the first turns between them. For this we use a bonding agent that is deposited directly on the sheet or indirectly via the spindle or one of the winding rolls, by a suitable system, at the time of winding the first turns on the spindle. Any other principle of association between them first turns, by mechanical process in particular, is applicable. We thus consolidate these first turns which together withstand the efforts of internal constraints.

Cependant, là encore, on ne peut éviter les déchets lors de la mise en service d'un tel rouleau. Que ce soit dans le cas d'une utilisation directe ou dans le cas où l'on utilise ce rouleau dans un distributeur à dévidage central dans lequel on doit introduire l'extrémité de la feuille dans un orifice de distribution relativement étroit, on est obligé d'éliminer au préalable les premières spires associées entre elles.However, again, the waste can not be avoided during the commissioning of such a roll. Whether in the case of direct use or in the case where this roller is used in a center-fed dispenser in which the end of the sheet must be introduced into a relatively narrow dispensing orifice, one is obliged to to eliminate beforehand the first coils associated with each other.

Dans ce dernier type de réalisation également, on ne peut éviter que certains rouleaux ne soient choqués lors du transport, avec comme conséquence l'affaissement du trou central comme dans les cas mentionnés plus haut. Pour éviter ce risque, on prévoit d'ailleurs de conditionner préférentiellement les rouleaux dans des caisses en carton, contrairement aux rouleaux avec mandrin qui se suffisent d'une enveloppe souple en papier ou en matière plastique. Le coût s'en trouve considérablement augmenté.In this latter type of embodiment also, it can not be avoided that some rollers are shocked during transport, with the result that the central hole collapses as in the cases mentioned above. To avoid this risk, it is also expected to preferentially condition the rolls in cardboard boxes, unlike rollers with mandrel that are sufficient of a flexible envelope of paper or plastic. The cost is considerably increased.

L'intérêt que l'on pouvait trouver à ces rouleaux sans mandrin par rapport aux rouleaux avec mandrin en est ainsi fortement diminué.The interest that could be found in these mandrel-free rolls compared to mandrel rollers is thus greatly reduced.

L'invention a donc pour objet un rouleau sans mandrin composé d'une feuille de matériau souple, tel qu'un matériau fibreux absorbant d'un grammage total compris entre 15 et 300 g/m2, préférentiellement entre 15 et 100 g/m2, formé par enroulement autour d'un axe de bobinage, qui ne présente pas les inconvénients rapportés ci-dessus.The subject of the invention is therefore a roll without mandrel composed of a sheet of flexible material, such as an absorbent fibrous material with a total basis weight of between 15 and 300 g / m 2 , preferably between 15 and 100 g / m 2 , formed by winding around a winding axis, which does not have the disadvantages reported above.

Le matériau absorbant peut être une ouate de cellulose, crêpée sec ou humide, un papier voie sèche ou un non-tissé. Il peut être composé d'un ou de plusieurs plis, associés ou non, éventuellement prédécoupés en coupons.The absorbent material may be cellulose wadding, dry or wet creped, dry paper or nonwoven. It can be composed of one or more plies, associated or not, possibly pre-cut into coupons.

Le matériau est à l'état sec. Il n'est pas humide; en particulier il n'est pas imprégné de lotion ou de tout autre liquide.The material is in the dry state. It is not wet; in particular it is not impregnated with lotion or any other liquid.

Conformément à l'invention, le rouleau est caractérisé par le fait qu'il comprend une amorce de dévidage central formant une saillie le long dudit axe de bobinage par rapport à au moins une partie du plan de l'un des flancs du rouleau, cette amorce est formée par rabattement transversal d'une portion de l'extrémité de la feuille sur l'axe de bobinage du rouleau. L'amorce peut être sur l'axe ou légèrement décalée par rapport à cet axe.According to the invention, the roll is characterized in that it comprises a central unwinding primer forming a projection along said winding axis with respect to at least a part of the plane of one of the sides of the roll, this primer is formed by transversely folding a portion of the end of the sheet on the winding axis of the roll. The primer may be on the axis or slightly offset relative to this axis.

L'invention s'applique en particulier aux rouleaux dont le bobinage est réalisé dans des conditions de forte tension de la feuille et de serrage sur le support de bobinage, qui permettent de produire, des rouleaux à fort métrage mais qui conduisent inévitablement à la réduction du trou central.The invention is applicable in particular to rollers whose winding is carried out under conditions of high tension of the sheet and clamping on the winding support, which make it possible to produce rolls with a strong film but which inevitably lead to the reduction. of the central hole.

Avantageusement, l'amorce de dévidage central est constituée d'une portion de l'extrémité interne de la feuille, formant le rouleau individuel.Advantageously, the central unwinding primer consists of a portion of the inner end of the sheet, forming the individual roll.

La solution de l'invention permet de se libérer de tous les problèmes liés à la réduction du trou central puisqu'on a accès à la première feuille depuis l'extérieur du rouleau. De ce fait, il n'est plus nécessaire de lier les premières spires entre elles pour essayer de maintenir le trou formé. On évite ainsi les déchets, tant au niveau de la machine de production en raison de l'absence de système d'association des spires, que lors de la mise en service du rouleau. On peut donc conditionner les rouleaux dans de simples remballages souples, notamment plastiques.The solution of the invention makes it possible to free oneself from all the problems related to the reduction of the central hole since one has access to the first sheet from outside the roll. Therefore, it is no longer necessary to bind the first turns together to try to maintain the hole formed. This avoids waste, both at the level of the production machine due to the absence of a system of association of the turns, than during the commissioning of the roll. We can therefore package the rollers in simple repacking flexible, including plastic.

En particulier, l'amorce est préférentiellement de forme effilée. On a alors l'avantage supplémentaire de faciliter l'introduction de l'extrémité de l'amorce dans le dispositif de distribution d'un distributeur à dévidage central, par exemple.In particular, the primer is preferably of tapered shape. There is then the additional advantage of facilitating the introduction of the end of the primer into the dispensing device of a center-fed dispenser, for example.

L'invention porte aussi sur un procédé pour fabriquer un rouleau de ce type.The invention also relates to a method for making a roll of this type.

Conformément à une caractéristique de l'invention, on réalise l'amorce avant bobinage par rabattement transversal par rapport à sa direction de déplacement d'une portion de l'extrémité avant de la feuille.According to a characteristic of the invention, the primer is carried out before winding by folding transversely relative to its direction of displacement of a portion of the front end of the sheet.

Ce principe s'applique dans un procédé avec ou sans support de bobinage. Une broche est un exemple de support de bobinage.This principle applies in a process with or without a winding support. A pin is an example of a winding support.

L'invention concerne en particulier un procédé comprenant les étapes dans lesquelles on dispose la feuille de façon qu'elle s'étende perpendiculairement à un support de bobinage, à proximité d'une extrémité de la dite feuille, on rabat ensuite l'extrémité de ladite feuille sur le support de bobinage, on maintient une portion de cette extrémité sur le support de bobinage, et on met celui-ci en rotation autour de son axe de façon à enrouler la feuille.The invention particularly relates to a method comprising the steps in which the sheet is arranged so that it extends perpendicularly to a winding support, near an end of said sheet, then the end of the sheet is folded down. said sheet on the winding support, a portion of this end is held on the winding support, and it is rotated about its axis so as to wind the sheet.

Conformément à l'invention, avant mise en rotation, on dispose la portion d'extrémité de façon à ce qu'elle s'étende en dehors de l'un des bords latéraux de la feuille.According to the invention, before rotation, the end portion is arranged so that it extends outside one of the lateral edges of the sheet.

Conformément à une autre caractéristique, on place le support de bobinage par rapport à la feuille, de manière qu'une portion de l'extrémité de la feuille soit disposée d'un côté du support de bobinage et le reste de la feuille, de l'autre ; on ramène ensuite ladite portion sur le support avec un déplacement transversal, c'est-à-dire dans une direction formant un angle non nul par rapport à la direction de défilement de la feuilleAccording to another characteristic, the winding support is placed with respect to the sheet, so that a portion of the end of the sheet is disposed on one side of the winding support and the remainder of the sheet, other; said portion is then brought back onto the support with a transverse displacement, that is to say in a direction forming a non-zero angle with respect to the direction of travel of the sheet

Conformément à une autre caractéristique, le déplacement transversal est assuré par projection d'air.According to another characteristic, the transverse displacement is provided by air projection.

Conformément à une variante, le déplacement transversal est assuré par le frottement d'une pièce sur la portion d'extrémité ; cette pièce se déplaçant avec un mouvement ayant une composante transversale. Le déplacement de la portion de l'extrémité de la feuille peut également être assuré par une simple rotation de la dite pièce.According to a variant, the transverse displacement is ensured by the friction of a piece on the end portion; this piece moving with a movement having a transverse component. Moving from the portion of the end of the sheet can also be provided by a simple rotation of said part.

Conformément à une autre caractéristique, on découpe une large feuille de matériau souple en une pluralité de feuilles individuelles disposées côte à côte ; on déplace transversalement, de préférence sur un même côté, une portion de l'extrémité desdites feuilles individuelles ; on enroule les dites feuilles autour d'un support de bobinage et on sépare ensuite chacun des rouleaux ainsi formés. La portion de l'extrémité desdites feuilles se trouve ainsi libéré au centre, lors de la séparation desdits rouleaux.According to another feature, a large sheet of flexible material is cut into a plurality of individual sheets arranged side by side; a portion of the end of said individual sheets is moved transversely, preferably on the same side; these sheets are wrapped around a winding support and then each of the rolls thus formed is separated. The portion of the end of said sheets is thus released in the center, during the separation of said rollers.

Conformément à un autre mode de réalisation du procédé, on découpe une large feuille de matériau souple en une pluralité de feuilles individuelles au moyen d'un dispositif de coupe, on bobine tout d'abord la ou les premières spires du rouleau, on déplace ensuite transversalement le dispositif de coupe, et on bobine le reste de la feuille pour former le rouleau. La ou les premières spires du rouleau se présentent ainsi en saillie sur l'un des flancs du rouleau, objet de l'invention.According to another embodiment of the method, a large sheet of flexible material is cut into a plurality of individual sheets by means of a cutting device, the first coil (s) of the roll are first reeled, then transversely the cutting device, and the remainder of the sheet is wound to form the roll. The first turn or turns of the roll are thus projecting on one of the sidewalls of the roll, object of the invention.

Conformément à un autre mode de réalisation du procédé, on bobine tout d'abord la ou les premières spires du rouleau, on déplace transversalement le support de bobinage par rapport au sens de déplacement de la feuille, et on bobine le reste de la feuille pour former le rouleau. La ou les premières spires du rouleau se présentent ainsi en saillie sur l'un des flancs du rouleau, objet de l'invention.According to another embodiment of the method, the first coil or turns of the roll are first wound, the winding support is moved transversely with respect to the direction of movement of the sheet, and the remainder of the sheet is wound for form the roll. The first turn or turns of the roll are thus projecting on one of the sidewalls of the roll, object of the invention.

On va maintenant décrire l'invention plus en détail en référence aux dessins joints en annexe sur lesquels:

  • la figure 1 représente un rouleau sans mandrin de l'art antérieur dont le trou central est réduit,
  • la figure 2 représente un rouleau de l'invention avec une amorce de dévidage central faisant saillie le long de l'axe par rapport à l'un des flancs du rouleau,
  • les figures 3 à 5 représentent schématiquement, en vue de profil, la progression d'une feuille dans une machine permettant de réaliser les rouleaux sans mandrin conformes à l'invention,
  • la figure 6 représente la machine selon la figure 4, vue de dessus.
The invention will now be described in more detail with reference to the appended drawings in which:
  • the figure 1 represents a mandrelless roll of the prior art whose central hole is reduced,
  • the figure 2 represents a roll of the invention with a central unwinding primer projecting along the axis with respect to one of the sides of the roll,
  • the Figures 3 to 5 schematically represent, in profile view, the progression of a sheet in a machine for producing the mandrelless rollers according to the invention,
  • the figure 6 represents the machine according to the figure 4 , top view.

Le rouleau représenté sur la figure 1, est par exemple un rouleau (R) de papier absorbant sans mandrin que l'on utilise pour l'essuyage ; soit à la maison, soit dans un atelier. A titre d'illustration, le papier est par exemple une ouate de cellulose à deux plis de 20 g/m2 chacun, préférentiellement associés. Le rouleau a été obtenu par enroulement d'une large feuille de 2600 mm de laize, sur un support de bobinage en forme de broche par exemple à section circulaire de diamètre de 10 à 80 mm. Après formation d'un rouleau, désigné « log » dans le domaine, de 20 cm de diamètre par exemple, on en extrait la broche et on le conduit à une station de sciage. Les rouleaux ainsi réalisés sont ensuite conditionnés pour l'expédition. On a représenté le rouleau après que les parois du trou central se sont effondrées dans la direction centrale. Le trou (T) est réduit jusqu'à se retrouver complètement aplati. Lors de la mise en service du rouleau dans un distributeur à dévidage central, on doit libérer l'extrémité interne de la feuille et la glisser dans l'orifice de distribution. On comprend que cette opération soit malaisée dans ce cas, car on doit tirer sur les premières spires pour dégager cette extrémité. Il en résulte inévitablement des déchets.The roll represented on the figure 1 is, for example, a roll (R) of absorbent paper without mandrel which is used for wiping; either at home or in a workshop. By way of illustration, the paper is, for example, a two-ply cellulose wadding of 20 g / m 2 each, preferably associated. The roll was obtained by winding a large sheet of 2600 mm width, on a spindle-shaped winding support for example circular section with a diameter of 10 to 80 mm. After forming a roll, designated "log" in the field, of 20 cm in diameter, for example, the spindle is extracted and led to a sawing station. The rolls thus produced are then packaged for shipping. The roll is shown after the walls of the central hole have collapsed in the central direction. The hole (T) is reduced until it is completely flattened. When commissioning the roller in a center-fed dispenser, the inner end of the sheet must be released and slid into the dispensing orifice. It is understood that this operation is difficult in this case, because we must pull on the first turns to clear this end. This inevitably results in waste.

La figure 2 montre un rouleau (10') sans mandrin conforme à l'invention. Le trou central est réduit comme dans le cas précédent de l'art antérieur. Cependant la mise en service du rouleau est largement facilitée par la solution de l'invention qui a consisté à former une amorce (10B) de dévidage central. Cette amorce est, selon le mode de réalisation le plus simple, constituée par une portion de l'extrémité interne de la feuille formant le rouleau que l'on a au préalable, avant tout affaissement des parois du trou central, libérée, et mise en saillie par rapport à l'un des flancs du rouleau. On peut former cette amorce, soit au moment de la formation du rouleau juste avant ou pendant l'enroulement de la feuille, soit après réalisation du rouleau quand le trou est encore formé, c'est à dire juste après la coupe, en tout état de cause, de préférence peu de temps après.The figure 2 shows a roll (10 ') without chuck according to the invention. The central hole is reduced as in the previous case of the prior art. However, the commissioning of the roll is largely facilitated by the solution of the invention which consisted in forming a central unwinding primer (10B). This primer is, according to the simplest embodiment, constituted by a portion of the inner end of the sheet forming the roller that is beforehand, before any collapse of the walls of the central hole, released, and setting protruding from one of sides of the roll. This primer can be formed, either at the time of forming the roll just before or during the winding of the sheet, or after making the roll when the hole is still formed, ie just after cutting, in any condition of cause, preferably soon after.

Avantageusement, cette amorce (10B), de 0,3 à 20 cm de long et de préférence de 1 cm à 15 cm, est formée d'une portion de l'extrémité interne de la feuille, que l'on a rabattue dans la direction de l'axe de bobinage du rouleau et fait déborder par rapport au flanc. Cette amorce forme ainsi une queue de préhension en pointe qui est souple à son extrémité et que l'on peut aisément rabattre contre le flanc du rouleau, pour procéder au conditionnement desdits rouleaux avant transport. En outre la pointe est maniable et peut être introduite aisément dans un distributeur. La longueur de l'amorce est choisie en particulier pour la facilité avec laquelle elle peut être saisie et avec laquelle elle peut être introduite dans l'orifice d'extraction d'un distributeur. La longueur de l'amorce correspond à la distance entre l'extrémité de l'amorce et le flanc du rouleau.Advantageously, this primer (10B), 0.3 to 20 cm long and preferably 1 cm to 15 cm, is formed of a portion of the inner end of the sheet, which is folded into the direction of the winding axis of the roll and is overflowed with respect to the sidewall. This primer thus forms a tip gripping tail which is flexible at its end and can be easily folded against the side of the roll, to proceed to the conditioning of said rollers before transport. In addition the tip is handy and can be easily introduced into a dispenser. The length of the primer is chosen in particular for the ease with which it can be grasped and with which it can be introduced into the extraction orifice of a dispenser. The length of the primer corresponds to the distance between the end of the primer and the side of the roll.

L'amorce peut être renforcée par un élément complémentaire, coloration par exemple.The primer can be reinforced by a complementary element, for example staining.

Selon un mode de réalisation non représenté, l'amorce peut être renforcée mécaniquement par une languette, ou tout moyen approprié, ou élément supplémentaire rapporté sur la feuille et agencé pour être en saillie sur l'axe du rouleau.According to an embodiment not shown, the primer can be mechanically reinforced by a tongue, or any appropriate means, or additional element attached to the sheet and arranged to project on the axis of the roller.

L'élément rajouté est alors disposé sur l'extrémité de la feuille avant bobinage ou après séparation des rouleaux, en saillie sur l'un des flancs du rouleau.The added element is then placed on the end of the sheet before winding or after separation of the rollers, projecting on one of the sides of the roll.

On décrit maintenant un premier mode de fabrication des rouleaux.A first method of manufacturing rolls is now described.

Sur les figures 3 à 6, on a représenté les éléments d'une machine permettant de réaliser-les-rouleaux sans mandrin de l'invention. Avec cette machine, on découpe en ligne une large feuille (1) issue d'une bobine mère (3), avant enroulement sur une broche (11). La largeur de la feuille dans le domaine des produits en papier absorbant est par exemple de 2600 mm. La feuille est coupée dans le sens longitudinal au moyen de lames (5) disposées en parallèle, en une pluralité de feuilles individuelles (10) dont la largeur correspond à la largeur des rouleaux individuels que l'on souhaite obtenir. Le moyen de coupe peut être constitué d'une série de lames disposées verticalement ou bien des disques coopérant avec un cylindre support et coupant la feuille. D'autres moyens sont connus de l'homme du métier.On the Figures 3 to 6 the elements of a machine for producing the mandrelless rollers of the invention are shown. With this machine, is cut in line a large sheet (1) from a mother reel (3), before winding on a spindle (11). The width of the sheet in the field of absorbent paper products is, for example, 2600 mm. The sheet is cut in the longitudinal direction by means of blades (5) arranged in parallel, in a plurality of individual sheets (10) whose width is the width of the individual rolls desired. The cutting means may consist of a series of blades arranged vertically or discs cooperating with a support cylinder and cutting the sheet. Other means are known to those skilled in the art.

Les feuilles (10) sont entraînées vers un dispositif comportant deux cylindres (7 et 9) parallèles et entraînés en rotation par des moyens moteurs non représentés. Les deux cylindres sont légèrement espacés l'un de l'autre. Une fois les feuilles (10) dans la position de la figure 3, on amène en place une broche (11) par des moyens appropriés. La broche vient pincer la feuille contre les cylindres (7 et 9), comme on le voit sur la figure 4. Elle chevauche l'espace ménagé entre ces deux cylindres d'entraînement contigus. La broche délimite ainsi d'un côté une portion d'extrémité (10A) des feuilles (10). Pour amorcer l'enroulement des feuilles sur la broche, on prévoit un moyen (15) qui rabat transversalement la portion d'extrémité (10A) sur la broche (11). Ce moyen peut être constitué par un ou plusieurs jets d'air judicieusement orientés. Puis, un rouleau presseur (13) est descendu pour venir maintenir l'extrémité (10A) des feuilles contre la broche. Une fois les différents organes en position, on entraîne les cylindres (7 et 9) en rotation. Ceux-ci font tourner la broche et le rouleau 13 sur eux-mêmes permettant l'enroulement de la feuille comme on le voit sur la figure 5.The sheets (10) are driven to a device comprising two cylinders (7 and 9) parallel and rotated by motor means not shown. The two cylinders are slightly spaced from each other. Once the leaves (10) in the position of the figure 3 a pin (11) is brought into place by appropriate means. The pin pinches the sheet against the cylinders (7 and 9), as seen on the figure 4 . It overlaps the space between these two contiguous drive cylinders. The pin thus delimits on one side an end portion (10A) of the sheets (10). To initiate the winding of the sheets on the spindle, there is provided a means (15) which folds transversely the end portion (10A) on the spindle (11). This means can be constituted by one or more air jets judiciously oriented. Then, a pressure roller (13) is lowered to hold the end (10A) of the sheets against the pin. Once the various members in position, the cylinders (7 and 9) are rotated. These rotate the spindle and the roller 13 on themselves allowing the winding of the sheet as seen on the figure 5 .

Lorsque l'étape d'enroulement est terminée, on relève le rouleau presseur et on déplace la broche avec ses rouleaux (10') jusqu'à la station suivante où on coupe les feuilles individuelles, parallèlement à l'axe de bobinage, sur toute la largeur de la feuille mère, en aval des cylindres (7 et 9). Puis, on extrait la broche de l'ensemble formé par les rouleaux (10').When the winding step is completed, the pressure roller is raised and the spindle is moved with its rollers (10 ') to the next station where the individual sheets are cut, parallel to the winding axis, over any the width of the mother sheet, downstream of the rolls (7 and 9). Then, the pin is extracted from the assembly formed by the rollers (10 ').

Conformément à l'invention, les rouleaux comportent en saillie sur l'axe, autrement dit en débordement par rapport à l'un des flancs du rouleau, une amorce (10B) de dévidage central.According to the invention, the rollers comprise projecting on the axis, in other words overflowing with respect to one of the sidewalls of the roll, a central unwinding primer (10B).

On réalise cette amorce au moment de l'enroulement des feuilles. On voit sur la figure 6, qui est une vue de dessus de l'installation correspondant à la vue de la figure 4, la broche (11) posé sur les deux cylindres (7 et 9) et pinçant la feuille. Les feuilles (101, 102,...) sont disposées en dessous de la broche (11) et leurs portions d'extrémité (10A1, 10A2, ...) rabattues transversalement sur celle-ci. Les moyens (15), ici constitués de jets d'air, sont inclinés sur l'axe de rotation de la broche de manière à imprimer à ces portions d'extrémité un mouvement de déplacement transversal par rapport à la direction de déplacement des feuilles. Ces portions d'extrémité (10A1, 10A2, ...), se trouvent ainsi déplacées dans la direction de l'axe de bobinage. Ainsi, chaque portion d'extrémité, (10A1) par exemple, vient déborder sur le côté en direction de la feuille voisine, (10A2). Une fois qu'elles sont dans cette position, le rouleau presseur (13) immobilise les différentes portions (10A1, 10A2, ....) d'extrémité contre la broche (11). L'enroulement peut commencer. Lors de l'enroulement, la partie débordante (10B1, 10B2, ...), de la portion d'extrémité de chacune des feuilles se retrouve pincée entre la broche et la première spire du rouleau voisin.This primer is made at the time of winding of the leaves. We see on the figure 6 , which is a top view of the installation corresponding to the view of the figure 4 , the pin (11) placed on the two cylinders (7 and 9) and pinching the sheet. The sheets (10 1 , 10 2 , ...) are arranged below the pin (11) and their end portions (10A 1 , 10A 2 , ...) folded transversely thereto. The means (15), here consisting of air jets, are inclined on the axis of rotation of the spindle so as to print at these end portions a displacement movement transverse to the direction of movement of the sheets. These end portions (10A 1 , 10A 2 , ...) are thus displaced in the direction of the winding axis. Thus, each end portion, (10A 1 ) for example, overflows on the side towards the adjacent sheet, (10A 2 ). Once they are in this position, the pressure roller (13) immobilizes the various end portions (10A 1 , 10A 2 , ....) against the pin (11). The winding can begin. During winding, the projecting portion (10B 1 , 10B 2 , ...) of the end portion of each of the sheets is pinched between the spindle and the first turn of the adjacent roll.

La partie débordante se trouve libérée au moment où l'on retire la broche. Cette partie (10B1, 10B2, ...), constitue alors l'amorce de dévidage central pour le rouleau.The overflowing portion is released when the pin is removed. This part (10B 1 , 10B 2 , ...), then constitutes the central unwinding primer for the roll.

Le moyen (15), pour rabattre les portions d'extrémité sur l'axe en leur imprimant un mouvement de déplacement transversal, a ici été représenté par des jets d'air orientés avec un certain angle, non droit, par rapport à l'axe de bobinage. Cependant, d'autres moyens sont connus et à la portée de l'homme du métier sans sortir du cadre de l'invention. Ce dernier peut être une brosse se déplaçant dans cette direction par exemple. Ce moyen peut être dédoublé, par un moyen pour le mouvement de rabattement et un moyen pour le déplacement dans la direction de l'axe de bobinage.The means (15), for folding the end portions on the axis by imparting to them a transverse displacement movement, has here been represented by air jets oriented at a certain angle, not straight, with respect to the winding axis. However, other means are known and within the reach of those skilled in the art without departing from the scope of the invention. The latter may be a brush moving in this direction for example. This means can be split by a means for the folding movement and a means for displacement in the direction of the winding axis.

Selon une variante, on découpe une large feuille de matériau souple au moyen du dispositif de coupe en une pluralité de feuilles individuelles (101, 102, ...) disposées côte à côte, et on réalise l'amorce (10B) par décalage transversal au sens d'enroulement de la feuille (10) du dispositif de coupe. On enroule ensuite les dites feuilles autour d'une broche (11) et on sépare chacun des rouleaux-après leur formation, les amorces (10B1, 10B2, ...) ainsi réalisées par les extrémités (10A1, 10A2, ...) desdites feuilles se présentent en saillie sur l'un des flancs du rouleau.According to one variant, a large sheet of flexible material is cut by means of the cutting device into a plurality of individual sheets (10 1 , 10 2 , ...) arranged side by side, and the primer (10B) is produced by transverse offset in the winding direction of the sheet (10) of the cutting device. The said sheets are then wrapped around a spindle (11) and each of the rollers is separated after their formation, the primers (10B 1 , 10B 2 , ...) thus produced by the ends (10A 1 , 10A 2 , ...) said sheets are projecting on one of the sides of the roll.

Selon encore une autre variante, on réalise l'amorce (10B) par décalage transversal au sens d'enroulement de la feuille (10) du support de bobinage, les amorces (10B1, 10B2, ...), issues des extrémités (10A1, 10A2, ...) des feuilles provenant de la découpe d'une large feuille de matériau souple en une pluralité de feuilles individuelles (101, 102, ...) disposées côte à côte, se présentent en saillie sur l'un des flancs du rouleau après la séparation desdits rouleaux.According to yet another variant, the primer (10B) is made by transverse shifting in the winding direction of the sheet (10) of the winding support, the primers (10B 1 , 10B 2 , ...) coming from the ends (10A 1 , 10A 2 , ...) sheets from the cutting of a large sheet of flexible material into a plurality of individual sheets (10 1 , 10 2 , ...) arranged side by side, projecting on one of the sides of the roll after separation of said rollers.

Le rabat transversal peut être réalisé indifféremment en direction de l'un ou l'autre des bords des feuilles individuelles (101, 102, ...) mais il est de préférence tourné dans le même sens que celui de l'extraction de la broche.The transverse flap can be made indifferently towards one or other of the edges of the individual sheets (10 1 , 10 2 , ...) but it is preferably rotated in the same direction as that of the extraction of spindle.

La longueur de l'amorce 10B faisant saillie dépend directement de la longueur de la portion d'extrémité 10A et de l'angle de rabat. Cette longueur 10B est préférentiellement comprise entre 0,3 et 20 cm.The length of the protruding primer 10B depends directly on the length of the end portion 10A and the flap angle. This length 10B is preferably between 0.3 and 20 cm.

On a mis en évidence que la très faible surépaisseur générée par l'amorce repliée sur le flanc du rouleau n'affectait pas la stabilité de la palettisation.It has been demonstrated that the very small thickness generated by the bent primer on the sidewall of the roll does not affect the stability of the palletizing.

L'invention peut être mise en oeuvre avec tout type de broche ou support de bobinage. Le profil et le diamètre peuvent être quelconques, dans la mesure où l'on peut extraire la broche une fois les rouleaux formés.The invention can be implemented with any type of pin or winding support. The profile and the diameter can be any, insofar as one can extract the pin once the formed rollers.

Avantageusement, la broche présente un état de surface avec un coefficient de friction approprié, tel que l'adjonction d'un agent lubrifiant s'avère être inutile.Advantageously, the spindle has a surface state with a suitable coefficient of friction, such that the addition of a lubricating agent turns out to be unnecessary.

Il n'est pas nécessaire que la largeur de la feuille soit un multiple du nombre de feuilles découpées. On peut avantageusement enrouler la rogne. Le rouleau de plus faible largeur ainsi formé sert alors d'amortisseur lors de l'extraction de la broche. Il est ensuite éliminé.The width of the sheet does not have to be a multiple of the number of cut sheets. We can advantageously wind the trim. The roll of smaller width thus formed then serves as a buffer during the extraction of the spindle. He is then eliminated.

La présente invention permet aussi de ne pas utiliser d'agent liant pour garder le trou ouvert après retrait de la broche. Une éventuelle réduction de la dimension du trou central avant emballage, ou même lors de chocs et/ou vibrations qui surviendraient pendant le transport, ne sont pas préjudiciables à la solution de l'invention. L'amorce (10B) de préhension reste disponible à l'utilisateur final.The present invention also makes it possible not to use a binding agent to keep the hole open after removal of the pin. Any reduction in the size of the central hole before packaging, or even during shocks and / or vibrations that would occur during transport, are not detrimental to the solution of the invention. The primer (10B) gripping remains available to the end user.

On a décrit l'invention pour une machine où l'alimentation de la broche était effectuée après arrêt de la machine. La présente invention s'applique aussi bien sûr aux cas où le changement de la broche est effectué sans arrêt de la machine. Dans le domaine, on qualifie de « cycle continu » ou « non stop », une telle machine. Cependant, l'opération de déport transversal de la portion d'extrémité de la feuille est dans ce cas plus délicate à réaliser puisque devant être effectuée dans un laps de temps très court. On surmonte cette difficulté en réduisant par exemple la vitesse de la machine.The invention has been described for a machine in which spindle feeding was performed after stopping the machine. The present invention also applies of course to cases where the change of the spindle is performed without stopping the machine. In the field, such a machine is described as "continuous cycle" or "non-stop". However, the operation of transverse offset of the end portion of the sheet is in this case more difficult to achieve since it must be done in a very short time. This difficulty is overcome by reducing, for example, the speed of the machine.

On a décrit un procédé avec enroulement autour d'une broche. Ce principe s'applique également à un procédé ne faisant pas appel à un support de bobinage.A method has been described with winding around a spindle. This principle also applies to a process that does not use a winding support.

Claims (17)

  1. Core-free roll (10') made up of a sheet (10) of unmoistened flexible material, such as an absorbent fibrous material, formed by winding the sheet about a winding axis, comprising a centre-feed start (10B) projecting along the said axis, with respect to at least part of the plane of one of the flanks of the roll, characterized in that the start (10B) is formed by folding the said end portion (10A) transversely onto the winding axis of the roll.
