The compression is produced by the rollers (10 and 11), which are used to drive the strip forward on to the cutter (3). An Independent claim is included for an apparatus for processing wood products utilizing the described method.

Description

La présente invention a pour objet un procédé de réalisation de sangles ou rubans de même épaisseur à partir de sangles ou rubans prélevés dans l'aubier d'arbres du type résineux, et destinés à être utilisés pour réaliser des décorations ou le cerclage de fromages, ainsi que le dispositif permettant la mise en oeuvre dudit procédé.The subject of the present invention is a method for producing straps or ribbons of the same thickness from straps or ribbons taken from the sapwood of coniferous trees, and intended to be used to make decorations or strapping of cheeses, as well as the device allowing the implementation of said method.

Il est actuellement fréquent d'utiliser des sangles prélevées dans l'aubier d'arbres du type résineux, soit dans le domaine de la décoration pour réaliser des oeuvres artistiques ou pour orner un bouquet de fleurs par exemple, soit dans le domaine de la pâtisserie pour cercler un gâteau, soit dans le domaine de la fromagerie pour cercler un fromage notamment lorsqu'il est crémeux afin de lui conserver sa forme.It is currently common to use removed straps in the sapwood of coniferous trees, or in the field decoration to create artistic works or for adorn a bouquet of flowers for example, either in the field of pastry to circle a cake, either in the area of the cheese dairy for strapping a cheese especially when it is creamy to keep it in shape.

L'aubier consiste en la partie jeune du tronc, c'est-à-dire la ou les dernières couches annuelles du bois, et il se situe donc entre le bois dur et l'écorce. Les sangles sont prélevées principalement dans les arbres du type résineux tels que les sapins et les épicéas, au moyen d'un outil du type gouge qui est déplacé dans le sens longitudinal de l'arbre, lequel qui aura été, de préférence, préalablement débarrassé de la partie rugueuse de son écorce.The sapwood consists of the young part of the trunk, i.e. the or the last annual layers of wood, so it’s between hardwood and bark. The straps are removed mainly in coniferous trees such as firs and spruces, using a gouge-type tool which is moved in the longitudinal direction of the tree, which will have been, preferably, previously rid of the part rough from its bark.

Cette opération nécessite une certaine dextérité pour permettre d'obtenir une sangle de bonne longueur et de largeur constante. Cependant, le fait de contrôler la largeur de la sangle ne permet pas d'obtenir une épaisseur constante sur une même sangle ou d'une sangle à une autre.This operation requires a certain dexterity to allow to obtain a strap of good length and constant width. However, controlling the width of the strap does not not allow to obtain a constant thickness on the same strap or from one strap to another.

Or, dans le domaine de la décoration où les sangles sont destinées très fréquemment à être cintrées, les variations d'épaisseur ne permettent pas d'obtenir une parfaite continuité de courbure, ce qui présente des inconvénients d'ordre esthétique.However, in the field of decoration where the straps are very frequently intended to be bent, variations thickness do not allow perfect continuity curvature, which has some drawbacks aesthetic.

D'autre part, dans le domaine de la fromagerie où le cerclage des fromages est souvent réalisé mécaniquement et automatiquement, il est indispensable que les sangles soient sensiblement toutes de même épaisseur et d'épaisseur constante.On the other hand, in the field of cheese making where the strapping cheese is often made mechanically and automatically, it is essential that the straps are substantially all of the same thickness and constant thickness.

Aussi, les méthodes actuelles de prélèvement de sangle engendrent beaucoup de pertes, ce qui accroít les coûts de production.Also, current methods of strap sampling cause a lot of losses, which increases the costs of production.

On connaít des dispositifs permettant de couper dans le sens de l'épaisseur des planches de liège pour en faire des feuilles de différentes épaisseurs, de tels dispositifs sont décrits dans les documents FR 425.665 et FR 1.576.628. Ces dispositifs comportent essentiellement un moyen d'entraínement de la planche à émincer, et un moyen de coupe disposé en sortie dudit moyen d'entraínement, celui-ci consistant en un rouleau cranté ou strié, mû en rotation et rappelé élastiquement en direction d'un support plan ou d'un rouleau.We know devices for cutting in the direction of the thickness of the cork planks to make sheets of different thicknesses, such devices are described in documents FR 425.665 and FR 1.576.628. These devices essentially include a means of training the slicing board, and a cutting means disposed at the outlet of said drive means, this consisting of a notched roller or striated, rotated, and spring-loaded in the direction a flat support or a roll.

Ces dispositifs et les procédés qu'ils mettent en oeuvre, sont destinés au traitement de l'écorce et plus particulièrement du liège, et ils ne peuvent pas permettre le traitement de l'aubier en vue de la fabrication de sangles, notamment en raison de l'épaisseur de la sangle lors de son prélèvement sur l'arbre, et qui est de l'ordre de quelques millimètres. Les moyens d'entraínement et de coupe décrits dans les documents évoqués précédemment, ne sont effectivement pas adaptés au traitement de sangles en aubier de si faible épaisseur.These devices and the methods they implement are intended for the treatment of bark and more particularly of cork, and they cannot allow the processing of sapwood for the production of straps, in particular because of the thickness of the strap when it is removed from the tree, and which is of the order of a few millimeters. The drive and cutting means described in the documents mentioned above, are not effectively adapted to the treatment of sapwood webbing so thin.

La présente invention a pour but de remédier aux divers inconvénients précités en proposant un procédé et son dispositif de mise en oeuvre, permettant de réaliser des sangles ou rubans de même épaisseur et d'épaisseur constante à partir de sangles ou rubans prélevés de manière traditionnelle dans l'aubier d'un arbre.The object of the present invention is to remedy the various disadvantages mentioned above by proposing a method and its implementation device, for making straps or ribbons of the same thickness and constant thickness from straps or ribbons traditionally taken from the sapwood of a tree.

Le procédé de réalisation de sangles ou rubans à partir de sangles ou rubans prélevés, au moyen d'un outil du type gouge, dans l'aubier d'arbres du type résineux, se caractérise essentiellement en ce qu'il consiste à découper longitudinalement et dans le sens de l'épaisseur la sangle ou le ruban prélevé peu de temps auparavant dans l'aubier pour former au moins une sangle d'épaisseur constante, tout en réalisant immédiatement avant l'opération de découpe une compression transversale linéaire bilatérale dans le sens de l'épaisseur de ladite sangle.The process for making straps or ribbons from straps or ribbons removed, using a gouge type tool, in the sapwood of coniferous trees, is characterized basically in that it involves cutting out longitudinally and in the thickness direction the strap or the ribbon taken shortly before from the sapwood for form at least one strap of constant thickness, while performing immediately before the cutting operation a bilateral linear transverse compression in the direction of the thickness of said strap.

La compression de la sangle permet d'une part de lui donner une forme plate, sachant qu'après son prélèvement elle peut présenter une forme incurvée, et d'autre part, du fait d'être linéaire et bilatérale, de réaliser une contrainte qui en réaction provoque en sortie de compression une expansion optimale favorisant la coupe, du fait de la dimension du bord offert à la coupe et de la tension dudit bord. On notera que les dispositifs existants ne permettent pas de réaliser une compression linéaire bilatérale.The compression of the strap allows on the one hand to give it a flat shape, knowing that after its removal it can present a curved shape, and on the other hand, the fact of being linear and bilateral, to realize a constraint which reaction causes expansion output to expand optimal for cutting, due to the size of the edge offered to cut and tension said edge. Note that existing devices do not allow for a bilateral linear compression.

Par ailleurs, l'expansion optimale ne peut être obtenue que si la sangle présente une grande élasticité, laquelle est conditionnée par la fraícheur de ladite sangle, l'opération de découpe doit donc de préférence être réalisée au plus tard dans le jour qui suit le prélèvement.Furthermore, optimal expansion can only be obtained if the strap has great elasticity, which is conditioned by the freshness of said strap, the operation of cutting should therefore preferably be carried out at the latest in the day after the withdrawal.

Le dispositif permettant la mise en oeuvre du procédé selon l'invention se caractérise essentiellement en ce qu'il comporte un moyen d'entraínement d'une sangle ou d'un ruban, prélevé peu de temps auparavant dans l'aubier d'un arbre du type résineux, dans son sens longitudinal, en direction d'un outil de coupe disposé en sortie dudit moyen d'entraínement et apte à réaliser une coupe dans le sens de l'épaisseur de ladite sangle ou dudit ruban, ledit moyen d'entraínement étant de plus apte à réaliser une compression transversale linéaire bilatérale dans le sens de l'épaisseur de ladite sangle.The device allowing the implementation of the method according to the invention is essentially characterized in that it comprises a means of driving a strap or a ribbon, taken little long ago in the sapwood of a coniferous tree, in its longitudinal direction, towards a cutting tool disposed at the outlet of said drive means and capable of producing a cut in the thickness direction of said strap or said ribbon, said drive means being further capable of producing a bilateral linear transverse compression in the direction of the thickness of said strap.

Selon une caractéristique additionnelle du dispositif selon l'invention, l'outil de coupe est animé d'un mouvement de vibration dans le sens longitudinal de son bord de coupe, perpendiculairement au sens d'avancement de la sangle.According to an additional characteristic of the device according to the invention, the cutting tool is animated by a movement of vibration in the longitudinal direction of its cutting edge, perpendicular to the direction of advancement of the strap.

Selon un mode de réalisation préférentiel du dispositif selon l'invention, le moyen d'entraínement consiste en deux rouleaux superposés dont l'un est fixe tandis que l'autre est mobile en déplacement de manière à pouvoir être amené au contact dudit rouleau fixe avec une certaine pression réglable.According to a preferred embodiment of the device according to the invention, the drive means consists of two rollers one of which is fixed while the other is movable in displacement so that it can be brought into contact with said fixed roller with a certain adjustable pressure.

Selon une caractéristique additionnelle du mode de réalisation préférentiel du dispositif selon l'invention, le rouleau mobile est susceptible de prendre des positions fixes par rapport au rouleau fixe, avec, pour chacune desdites positions fixes, une possibilité de jeu rappelé élastiquement.According to an additional characteristic of the embodiment preferred device according to the invention, the movable roller is likely to take fixed positions relative to the fixed roller, with, for each of said fixed positions, a possibility of elastically recalled play.

Les deux rouleaux permettent de réaliser une compression linéaire bilatérale par l'intermédiaire des deux génératrices en regard, le moyen de coupe étant disposé à courte distance desdites génératrices.Two rollers allow compression linear bilateral via the two generators opposite, the cutting means being arranged at a short distance of said generators.

Les avantages et les caractéristiques du procédé et dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the process and device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé:

  • la figure 1 représente une vue schématique d'un dispositif permettant la mise en oeuvre du procédé selon l'invention.
  • la figure 2 représente une vue schématique d'un détail de la figure 1.
In the attached drawing:
  • Figure 1 shows a schematic view of a device for implementing the method according to the invention.
  • FIG. 2 represents a schematic view of a detail of FIG. 1.

Si on se réfère à la figure 1, on peut voir qu'un dispositif mettant en oeuvre le procédé selon l'invention comporte un moyen 1 d'entraínement d'une sangle 2 prélevée préalablement dans l'écorce d'un arbre, ainsi qu'un outil de coupe 3.If we refer to Figure 1, we can see that a device implementing the method according to the invention comprises means 1 drive a strap 2 previously taken from the bark of a tree, as well as a cutting tool 3.

Le moyen d'entraínement 1 comprend deux rouleaux 10 et 11 disposés l'un au-dessus de l'autre, le rouleau inférieur 10 étant fixe, tandis que le rouleau supérieur 11 est mobile en rapprochement ou en éloignement par rapport au rouleau inférieur 10.The drive means 1 comprises two rollers 10 and 11 arranged one above the other, the lower roller 10 being fixed, while the upper roller 11 is movable in approaching or moving away from the roller lower 10.

La position du rouleau supérieur 11 par rapport au rouleau inférieur 10 est réglable, avec toutefois pour chacune des positions qu'il peut prendre fixement la possibilité d'un certain jeu rappelé élastiquement.The position of the upper roller 11 relative to the roller lower 10 is adjustable, however for each of the positions he can steadily take the possibility of a certain game recalled elastically.

Les rouleaux 10 et 11 sont mus en rotation dans des sens inverses A et B, et à la même vitesse par un moyen moteur 4 de type connu qui comprend une roue d'entraínement 40, une courroie 41, un renvoi d'angle mobile 42 et deux roues 43 et 44 identiques accolées chacune coaxialement à l'un des rouleaux 10 et 11.Rollers 10 and 11 are rotated in directions reverse A and B, and at the same speed by a motor means 4 of known type which includes a drive wheel 40, a belt 41, a movable bevel gear 42 and two wheels 43 and 44 identical, each attached coaxially to one of the rollers 10 and 11.

La sangle 2 à couper, qui a été prélevée peu de temps auparavant dans l'aubier d'un arbre du type résineux, est placée sur un plateau 5 et est poussée entre les rouleaux 10 et 11 qui, par leur rotation, l'entraínent en la pinçant entre deux génératrices.Strap 2 to be cut, which was removed shortly previously in the sapwood of a coniferous tree, is placed on a plate 5 and is pushed between the rollers 10 and 11 which, by their rotation, entrain it by pinching it between two generators.

L'outil de coupe 3 est positionné à proximité des rouleaux 10 et 11, et plus particulièrement à faible distance de la zone de pincement de la sangle 2.The cutting tool 3 is positioned near the rollers 10 and 11, and more particularly at a short distance from the pinching of the strap 2.

L'outil de coupe 3 est animé d'un mouvement de vibration dans le sens longitudinal de son bord de coupe 30, c'est-à-dire parallèlement aux axes de rotation des rouleaux 10 et 11.The cutting tool 3 is animated by a vibration movement in the longitudinal direction of its cutting edge 30, that is to say parallel to the axes of rotation of the rollers 10 and 11.

La vibration de l'outil de coupe 3 peut être obtenue de différentes manières connues en soi, au moyen d'un excentrique par exemple.The vibration of the cutting tool 3 can be obtained from different ways known per se, by means of an eccentric for example.

On notera que la coupe peut être réalisée différemment au moyen d'une lame oscillante ou d'une lame circulaire mue en rotation.Note that the cut can be made differently using an oscillating blade or a circular blade rotated.

A la sortie des rouleaux 10 et 11, l'outil de coupe 3 coupe la sangle 1 dans le sens de l'épaisseur et la sépare en deux rubans, un ruban inférieur 20 et un ruban supérieur 21.At the exit of the rollers 10 and 11, the cutting tool 3 cuts the strap 1 in the thickness direction and separates it in two ribbons, a lower ribbon 20 and an upper ribbon 21.

La position de l'outil de coupe 3 est fixe par rapport au rouleau inférieur 10, en sorte que lors de la coupe le ruban inférieur 20 soit toujours de même épaisseur.The position of the cutting tool 3 is fixed relative to the lower roller 10, so that when cutting the ribbon lower 20 is always the same thickness.

On notera qu'il peut être prévu un réglage de la position de l'outil de coupe 3 par rapport au rouleau inférieur 10, de manière à permettre la réalisation de rubans inférieurs 20 d'épaisseurs différentes.It will be noted that provision may be made for adjusting the position of the cutting tool 3 relative to the lower roller 10, so as to allow the production of lower ribbons 20 of different thicknesses.

Le ruban supérieur 21, selon son épaisseur et la régularité de celle-ci, est soit jeté, soit conservé tel quel, soit coupé dans le sens de l'épaisseur une seconde fois. The upper strip 21, depending on its thickness and the regularity of it is either discarded, kept as it is, or cut in the thickness direction a second time.

Le réglage de la position du rouleau supérieur 11 par rapport au rouleau inférieur 10 permet de traiter des sangles 1 de différentes épaisseurs, la possibilité de jeu permet d'absorber les variations d'épaisseur d'une même sangle 1, de deux sangles 1 d'épaisseurs proches.Adjusting the position of the upper roller 11 relative to with the lower roller 10 allows to treat straps 1 of different thicknesses, the possibility of play allows to absorb variations in thickness of the same strap 1, of two straps 1 of close thickness.

Si on se réfère maintenant à la figure 2, on peut voir que lors du pincement entre les deux rouleaux 10 et 11 de la sangle 1, celle-ci est comprimée plus qu'il ne faut pour l'entraíner en déplacement.If we now refer to Figure 2, we can see that during pinching between the two rollers 10 and 11 of the strap 1, it is compressed more than it takes to drive it displacement.

La compression de la sangle 1 a pour but d'une part de l'aplatir, sachant que la sangle 1 est à l'origine légèrement incurvée dans le sens transversal, et d'autre part de provoquer par réaction à la sortie des rouleaux 10 et 11, le relâchement de ses fibres et son expansion de manière à présenter à l'outil de coupe 3 une épaisseur la plus large possible, et une tension dans le sens de l'épaisseur qui facilite la coupe.The compression of the strap 1 aims on the one hand to flatten it, knowing that the strap 1 is originally slightly curved in the transverse direction, and on the other hand to cause by reaction at the exit of the rollers 10 and 11, the slackening of its fibers and its expansion so as to present to the tool of cutting 3 the widest possible thickness, and a tension in the direction of the thickness which facilitates the cut.

Le procédé et le dispositif selon l'invention permettent d'obtenir des sangles ou des rubans d'épaisseur constante à partir de sangles ou rubans prélevés de manière traditionnelle.The method and the device according to the invention allow to obtain straps or ribbons of constant thickness at from straps or ribbons taken in the traditional way.

Avantageusement, outre le fait que toutes les sangles d'origine peuvent être utilisées, le nombre de sangles produites est très supérieur au nombre desdites sangles d'origine, ce qui en réduit le coût.Advantageously, in addition to the fact that all the original straps can be used, the number of straps produced is very greater than the number of said original straps, which reduces the cost.
