La présente invention se rapporte au domaine technique général du machinisme agricole. Elle concerne plus précisément une faucheuse- conditionneuse de fourrage comportant un châssis portant un groupe de fauche qui comporte un dispositif de coupe et un dispositif de traitement du fourrage destiné à accélérer le séchage du produit coupé. Ce dispositif de traitement comporte un rotor de conditionnement constitué par : - un support entraîné en rotation autour de son axe longitudinal, et - des éléments de conditionnement liés audit support de manière à venir au contact d'un produit coupé, lesdits éléments de conditionnement sont répartis sur ledit support suivant au moins une disposition élémentaire, dans ladite au moins une disposition élémentaire, lesdits éléments de conditionnement sont disposés suivant au moins quatre rangées, vu suivant un plan radial audit axe longitudinal, lesdites rangées étant réparties uniformément sur l'intégralité de la périphérie dudit support, de plus dans ladite au moins une disposition élémentaire, lesdits éléments de conditionnement sont décalés les uns par rapport aux autres le long dudit axe longitudinal. Un tel rotor de conditionnement est décrit dans le document US 4,545,188.The present invention relates to the general technical field of agricultural machinery. More specifically, it relates to a forage mower-conditioner comprising a frame carrying a mowing group which comprises a cutting device and a forage treatment device intended to accelerate the drying of the cut product. This processing device comprises a conditioning rotor constituted by: - a support driven in rotation about its longitudinal axis, and - conditioning elements linked to said support so as to come into contact with a cut product, said conditioning elements are distributed on said support in at least one elementary arrangement, in said at least one elementary arrangement, said conditioning elements are arranged in at least four rows, seen along a plane radial to said longitudinal axis, said rows being distributed uniformly over the entire the periphery of said support, moreover in said at least one elementary arrangement, said packaging elements are offset with respect to each other along said longitudinal axis. Such a conditioning rotor is described in document US 4,545,188.
Ce type de rotor est utilisé dans le domaine agricole pour accélérer le séchage d'un produit coupé, comme de l'herbe par exemple. Pour ce faire, le rotor est entraîné en rotation de manière à ce que les éléments de conditionnement viennent impacter le produit coupé. Ces impacts facilitent l'évaporation de l'humidité contenue dans les plantes, d'où un séchage plus rapide. La vitesse de rotation de ces rotors est communément de l'ordre de 1000 tours par minute. Il est donc nécessaire que le rotor soit bien équilibré pour éviter de générer des vibrations néfastes à la tenue mécanique du rotor et au confort de l'utilisateur. Le balourd initial d'un rotor provient d'une part des tolérances géométriques sur les pièces constituant le rotor, et d'autre part de l'emplacement même des éléments de conditionnement sur le support. Dans certains cas, il s'avère que l'emplacement rotor. Dans le procédé actuel de fabrication, il est donc prévu une opération d'équilibrage consistant à ramener le balourd du rotor dans des valeurs acceptables. Le but de la présente invention est de réduire, voire même de supprimer, le balourd engendré par l'emplacement des éléments de conditionnement sur le support. A cet effet, le rotor de conditionnement de la faucheuse-conditionneuse selon la présente invention est caractérisé par le fait que ladite au moins une disposition élémentaire comporte 23Vrangées, W étant pair, et ladite au moins une disposition élémentaire se compose : - d'une première demi-disposition de 2W éléments de conditionnement, vu suivant ledit plan radial, lesdits 23V éléments de conditionnement sont répartis uniformément sur l'intégralité de la périphérie dudit support, et - d'une deuxième demi-disposition de 25V éléments de conditionnement, ladite deuxième demi-disposition étant obtenue par une rotation de 180 degrés de ladite première demi-disposition autour dudit axe longitudinal et par une translation suivant ledit axe longitudinal. Selon une variante, le rotor de conditionnement de la faucheuse- conditionneuse selon la présente invention est caractérisé par le fait que ladite au moins une disposition élémentaire comporte 2Wrangées, 5V étant impair, et ladite au moins une disposition élémentaire se compose : - d'une première demi-disposition de W éléments de conditionnement, vu suivant ledit plan radial, lesdits W éléments de conditionnement sont répartis uniformément sur l'intégralité de la périphérie dudit support, et - d'une deuxième demi-disposition de Wéléments de conditionnement, ladite deuxième demi-disposition étant obtenue par une rotation de 180 degrés de ladite première demi-disposition par rapport audit axe longi dinal et par une translation suivant ledit axe longitudinal. Ainsi le balourd engendré par l'emplacement des éléments de conditionnement étant largement réduit, voire nul. Le balourd initial du rotor estThis type of rotor is used in the agricultural field to accelerate the drying of a cut product, such as grass for example. To do this, the rotor is rotated so that the packaging elements impact the cut product. These impacts facilitate the evaporation of the moisture contained in the plants, resulting in faster drying. The rotational speed of these rotors is commonly of the order of 1000 revolutions per minute. It is therefore necessary that the rotor is well balanced to avoid generating harmful vibrations to the mechanical strength of the rotor and to the comfort of the user. The initial unbalance of a rotor comes on the one hand from the geometric tolerances on the parts constituting the rotor, and on the other hand from the very location of the packaging elements on the support. In some cases, it turns out that the location rotor. In the current manufacturing process, there is therefore provided a balancing operation consisting in bringing the unbalance of the rotor back to acceptable values. The object of the present invention is to reduce, or even eliminate, the unbalance generated by the location of the packaging elements on the support. To this end, the conditioning rotor of the mower-conditioner according to the present invention is characterized in that said at least one elementary arrangement comprises 23 lines, W being even, and said at least one elementary arrangement consists of: first half-arrangement of 2W conditioning elements, seen along said radial plane, said 23V conditioning elements are distributed uniformly over the entire periphery of said support, and - of a second half-arrangement of 25V conditioning elements, said second half-arrangement being obtained by a rotation of 180 degrees of said first half-arrangement around said longitudinal axis and by a translation along said longitudinal axis. According to a variant, the conditioning rotor of the mower-conditioner according to the present invention is characterized in that said at least one elementary arrangement comprises 2 rows, 5V being odd, and said at least one elementary arrangement consists of: first half-arrangement of W conditioning elements, seen along said radial plane, said W conditioning elements are distributed uniformly over the entire periphery of said support, and - a second half-arrangement of conditioning elements, said second half arrangement being obtained by a 180 degree rotation of said first half arrangement relative to said longitudinal axis and by translation along said longitudinal axis. Thus the imbalance generated by the location of the packaging elements is greatly reduced, or even zero. The initial unbalance of the rotor is

L'opération d'équilibrage du rotor n'est donc plus nécessaire. La fabrication d'un rotor selon la présente invention est par conséquent plus rapide et moins onéreuse. D'autres caractéristiques de l'invention, à considérer séparément ou dans toutes leurs combinaisons possibles, apparaîtront encore dans la description suivante d'exemples de réalisation non limitatifs de l'invention représentés sur les dessins annexés sur lesquels : - la figure 1 représente, vue de coté, une faucheuse agricole selon la présente invention, - la figure 2 représente, vue de coté et à une autre échelle, une coupe du groupe de fauche de la faucheuse visible à la figure 1, - la figure 3 représente un premier exemple de disposition des éléments de conditionnement sur le support du rotor, - la figure 4 représente un deuxième exemple de disposition des éléments de conditionnement sur le support du rotor, - la figure 5 représente un troisième exemple de disposition des éléments de conditionnement sur le support du rotor. La figure 1 représente, vu de coté, une machine agricole conforme à la présente invention, et plus précisément une faucheuse-conditionneuse (1). Ladite faucheuse-conditionneuse (1) est attelée à un véhicule moteur (2) qui la tire suivant une direction et un sens d'avance représenté par la flèche (3). Dans la suite de la description, les notions suivantes "avant" et "arrière", "devant" et "derrière" sont définies par rapport au sens d'avance (3) et les notions "droite" et "gauche" sont définies en regardant ladite faucheuse (1) de l'arrière dans le sens d'avanceArmr * Ari nninnomptit ctvrY nΛ &ranr'ac! m γmpi-rïπτif »e oπr 1P» C rvipr> £ »e T p» e fr lr r {inpf »« geometric on the parts being well controlled, they thus generate an unbalance which is much lower than the total unbalance admissible for the rotor. The balancing operation of the rotor is therefore no longer necessary. The manufacture of a rotor according to the present invention is therefore faster and less expensive. Other characteristics of the invention, to be considered separately or in all their possible combinations, will appear further in the following description of nonlimiting exemplary embodiments of the invention shown in the accompanying drawings in which: - Figure 1 shows, side view, an agricultural mower according to the present invention, - Figure 2 shows, side view and on another scale, a section of the mower group of the mower visible in Figure 1, - Figure 3 shows a first example arrangement of the conditioning elements on the rotor support, - Figure 4 shows a second example of arrangement of the conditioning elements on the rotor support, - Figure 5 shows a third example of arrangement of the conditioning elements on the support of the rotor. Figure 1 shows, seen from the side, an agricultural machine according to the present invention, and more specifically a mower-conditioner (1). Said mower-conditioner (1) is coupled to a motor vehicle (2) which pulls it in a direction and a direction of advance represented by the arrow (3). In the following description, the following concepts "front" and "rear", "front" and "behind" are defined with respect to the direction of advance (3) and the concepts "right" and "left" are defined in looking at said mower (1) from the rear in the forward direction
(3). Dans l'exemple de réalisation représenté à la figure 1, ladite faucheuse- conditionneuse (1) est du type traînée. Elle comporte donc plus précisément un châssis (4), un timon (6) et un groupe de fauche (7). Ledit châssis (4) repose sur le sol au moyen de deux roues (5). De plus, ledit châssis (4) est lié à l'arrière dudit véhicule moteur (2) au moyen d'un timon (6). D'une manière connue, ledit timon de travail et une position de transport. Pour sa part, ledit groupe de fauche (7) est lié audit châssis (4) au moyen d'un dispositif de suspension. Ledit dispositif de suspension permet avantageusement audit groupe de fauche (7) de suivre les dénivellations du sol mdépenci rnment de la position dudit châssis (4). Ledit dispositif de suspension permet en sus de reporter, lors du travail, une partie du poids dudit groupe de fauche (7) sur ledit châssis (4). Un tel dispositif de suspension est connu de l'homme de l'art, il ne sera donc pas décrit d'avantage. Ledit groupe de fauche (7) est destiné, lors du travail, à couper un produit sur pied tel que de l'herbe par exemple. A cet effet et à la lumière de la figure 2, ledit groupe de fauche (7) comporte un dispositif de coupe (8) et un dispositif de traitement du fourrage (9). Dans l'exemple de réalisation représenté sur la figure 2, ledit dispositif de coupe (8) comporte plusieurs organes de coupe (10) disposés côte à côte suivant une ligne transversale à ladite direction d'avance (3). Chaque organe de coupe (10) supporte avantageusement deux éléments de coupe (11) encore appelés couteaux. Lors du travail, lesdits organes de coupe (10) sont entraînés en rotation autour d'un axe respectif sensiblement vertical. Lesdits éléments de coupe (11) décrivent alors des cercles dans un plan sensiblement horizontal. La vitesse de déplacement relativement importante desdits éléments de coupe (11), due essentiellement à la rotation desdits organes de coupe (10), permet de couper le produit sur pied et d'entraîner le produit coupé vers l'arrière. Un tel dispositif de coupe (8) est connu de l'homme de l'art, il ne sera donc pas décrit d'avantage. Pour sa part, ledit dispositif de traitement du fourrage (9) est destiné à accélérer le séchage du produit coupé par ledit dispositif de coupe (8). Pour ce faire, ledit dispositif de traitement du fourrage (9) comporte un rotor (12) disposé en arrière dudit dispositif de coupe (8). Ledit rotor (12) comporte à son tour un support (14) et des éléments de conditionnement (15). Lors du travail, ledit support (14) est entraîné en rotation autour de son axe longitudinal (14a), ledit axe longitudinal (14a) étant sensiblement horizontal et transversal à ladite direction d'avance (3). Lesdits éléments de conditionnement (15) sont quant à eux liés audit support (14) de manière à s'étendre suivant une direction sensiblement radiale par figure 2, lesdits éléments de conditionnement (15) sont avantageusement liés de manière pivotante audit support (14) au moyen d'une articulation respective (16) d'axe sensiblement parallèle audit axe longitudinal (14a) dudit support (14). En cas de choc avec un obstacle, lesdits éléments de conditionnement (15) peuvent ainsi s'esquiver, on évite alors tout risque d'endommagement. Selon un autre exemple de réalisation non représenté, lesdits éléments de conditionnement (15) sont liés rigidement audit support (14). Lors du travail, lesdits éléments de conditionnement (15) viennent au contact du produit coupé. D'une manière préférentielle, lesdits éléments de conditionnement (15) emmènent ensuite le produit coupé le long d'une tôle de conditionnement (13) avant de l'éjecter à l'arrière dudit groupe de fauche (7). D'une manière connue de l'homme de l'art, l'impact des éléments de conditionnement (15) et le passage le long de ladite tôle de conditionnement (13) provoque une fragmentation du produit coupé propice à un séchage rapide de ce dernier. D'une manière également connue de l'homme de l'art, ladite faucheuse- conditionneuse (1) comporte en sus des éléments de transmission destinés à transmettre un mouvement de rotation d'une prise de force dudit véhicule moteur (2) jusqu'auxdits éléments de coupe (10) et audit rotor (12). Les figures 3 à 5 représentent trois exemples de rotor (12) conformes à la présente invention. Sur ces figures, la périphérie dudit support (14) a été représentée à plat de manière à mieux distinguer la disposition desdits éléments de conditionnement (15) sur ledit support (14). Plus précisément, les figures 3 et 4 représentent chacune un exemple de disposition élémentaire desdits éléments de conditionnement (15) sur ledit support (14). Ledit rotor (12) conforme à la présente invention peut comporter une seule disposition élémentaire. Dans ce cas, les figures 3 et 4 représentent ledit rotor (12) dans sa globalité. Cependant, ledit rotor (12) conforme à la présente invention peut également comporter plusieurs dispositions élémentaires identiques, réparties le long dudit axe longitudinal (14a). Les figures 3 et 4 représentent alors une portion dudit rotor (12). Pour sa part, la figure 5 représente un autre exemple où ledit rotor (12) comporte cette fois différentes dispositions élémentaires. Dans une disposition élémentaire, lesdits éléments de conditionnement (15) sont répartis suivant au moins quatre rangées (18). Vues suivant un plan radial audit axe longitudinal (14a), lesdites rangées (18) sont réparties uniformément sur l'intégralité de la périphérie dudit support (14). Dans l'exemple de réalisation représenté à la figure 2, lesdits éléments de conditionnement (15) sont disposés plus précisément suivant huit rangées (18). L'écart angulaire entre chaque rangée(3). In the embodiment shown in Figure 1, said mower-conditioner (1) is of the trailed type. It therefore more precisely comprises a chassis (4), a drawbar (6) and a mowing group (7). Said frame (4) rests on the ground by means of two wheels (5). In addition, said chassis (4) is connected to the rear of said motor vehicle (2) by means of a drawbar (6). In a known manner, said drawbar work and transport position. For its part, said mowing group (7) is linked to said chassis (4) by means of a suspension device. Said suspension device advantageously allows said mowing group (7) to follow the unevenness of the ground mdépenci rnment of the position of said frame (4). Said suspension device makes it possible, in addition, to transfer, during work, part of the weight of said mowing unit (7) to said chassis (4). Such a suspension device is known to those skilled in the art, so it will not be described further. Said mowing group (7) is intended, during work, to cut a standing product such as grass for example. To this end and in the light of FIG. 2, said mowing group (7) comprises a cutting device (8) and a forage treatment device (9). In the embodiment shown in Figure 2, said cutting device (8) comprises several cutting members (10) arranged side by side along a line transverse to said direction of advance (3). Each cutting member (10) advantageously supports two cutting elements (11) also called knives. During work, said cutting members (10) are rotated about a respective substantially vertical axis. Said cutting elements (11) then describe circles in a substantially horizontal plane. The relatively high speed of movement of said cutting elements (11), due essentially to the rotation of said cutting members (10), makes it possible to cut the product on the stand and to drive the cut product backwards. Such a cutting device (8) is known to those skilled in the art, it will therefore not be described further. For its part, said fodder treatment device (9) is intended to accelerate the drying of the product cut by said cutting device (8). To do this, said forage treatment device (9) comprises a rotor (12) disposed behind said cutting device (8). Said rotor (12) in turn comprises a support (14) and conditioning elements (15). During work, said support (14) is rotated about its longitudinal axis (14a), said longitudinal axis (14a) being substantially horizontal and transverse to said direction of advance (3). Said conditioning elements (15) are in turn connected to said support (14) so as to extend in a substantially radial direction by Figure 2, said packaging elements (15) are advantageously pivotally connected to said support (14) by means of a respective articulation (16) with an axis substantially parallel to said longitudinal axis (14a) of said support (14). In the event of an impact with an obstacle, said packaging elements (15) can thus slip away, any risk of damage is then avoided. According to another embodiment not shown, said packaging elements (15) are rigidly connected to said support (14). During work, said packaging elements (15) come into contact with the cut product. Preferably, said packaging elements (15) then take the cut product along a packaging sheet (13) before ejecting it at the rear of said mowing group (7). In a manner known to a person skilled in the art, the impact of the packaging elements (15) and the passage along said packaging sheet (13) causes fragmentation of the cut product which is conducive to rapid drying of this product. latest. In a manner also known to those skilled in the art, said mower-conditioner (1) comprises in addition transmission elements intended to transmit a rotational movement from a power take-off from said motor vehicle (2) to to said cutting elements (10) and to said rotor (12). Figures 3 to 5 show three examples of rotor (12) according to the present invention. In these figures, the periphery of said support (14) has been shown flat so as to better distinguish the arrangement of said packaging elements (15) on said support (14). More specifically, Figures 3 and 4 each show an example of an elementary arrangement of said packaging elements (15) on said support (14). Said rotor (12) according to the present invention may comprise a single elementary arrangement. In this case, Figures 3 and 4 show said rotor (12) as a whole. However, said rotor (12) according to the present invention may also include several identical elementary arrangements, distributed along said longitudinal axis (14a). Figures 3 and 4 then represent a portion of said rotor (12). For its part, FIG. 5 represents another example where said rotor (12) this time comprises different elementary arrangements. In an elementary arrangement, said conditioning elements (15) are distributed in at least four rows (18). Viewed along a plane radial to said longitudinal axis (14a), said rows (18) are distributed uniformly over the entire periphery of said support (14). In the embodiment shown in Figure 2, said packaging elements (15) are arranged more precisely in eight rows (18). The angular difference between each row
(18) vaut donc ici 45 degrés. Lesdites rangées (18) s'étendent suivant une direction parallèle audit axe longitudinal (14a) dudit support (14). Dans une disposition élémentaire, lesdits éléments de conditionnement (15) sont en sus décalés les uns par rapport aux autres le long dudit axe longitudinal (14a). Ainsi lors de la rotation dudit rotor (12), on ne trouve jamais deux éléments de conditionnement (15) exactement dans le prolongement l'un de l'autre. Sans pour autant sortir du cadre de la présente invention, la valeur du décalage peut être inférieure à la largeur d'un élément de conditionnement (15) de manière à avoir un chevauchement partiel desdits éléments de conditionnement (15). Selon une caractéristique importante de la présente invention, ladite disposition élémentaire comporte 25V rangées, 5V étant pair, et ladite disposition élémentaire se compose : - d'une première demi-disposition de 25 éléments de conditionnement (15), vus suivant ledit plan radial, lesdits 25V éléments de conditionnement (15) sont répartis uniformément sur l'intégralité de la périphérie dudit support (14), et - d'une deuxième demi-disposition de 25V éléments de conditionnement (15), ladite deuxième demi-disposition étant obtenue par une rotation de 180 degrés de ladite première demi-disposition autour dudit axe longitudinal (14a), et par une translation suivant ledit axe longitudinal (14a). Selon une variante de la présente invention, ladite disposition élémentaire comporte 25V rangées, 5V étant impair, et ladite disposition élémentaire se compose : - d'une première demi-disposition de 5V éléments de conditionnement (15), vus suivant ledit nlan radial, lesdits 5V éléments de conditionnement Cl 5) sont répartis uniformément sur l'intégralité de la périphérie dudit support (14), et - d'une deuxième demi-disposition de 5V éléments de conditionnement (15), ladite deuxième demi-disposition étant obtenue par une rotation de 180 degrés de ladite première demi-disposition autour dudit axe longitudinal (14a), et par une translation suivant ledit axe longitudinal (14a). La figure 3 représente un exemple de disposition élémentaire où 5Vest pair. Plus précisément, 5Vest ici égale à deux. Lesdits éléments de conditionnement (15) sont donc répartis suivant quatre rangées (18a, 18b, 18c, 18d), chaque rangée (18a, 18b, 18c, 18d) étant décalée angulairement de 90 degrés. Les quatre éléments de conditionnement (15a, 15b, 15c, 15d) constituent ladite première demi- disposition. Lesdits éléments de conditionnement (15a, 15b, 15c, 15d) occupent chacun une rangée respective (18a, 18b, 18c, 18d). Lesdits éléments de conditionnement (15a, 15b, 15c, 15d) sont donc répartis uniformément sur les 360 degrés dudit support (14). Dans ladite première demi-disposition, lesdits éléments de conditionnement (15a, 15b, 15c, 15d) sont décalés les uns des autres suivant ledit axe longitudinal (14a) d'une distance de décalage (17) constante. Les quatre éléments de conditionnement (15e, 15f, 15g, 15h) constituent ladite deuxième demi-disposition. La position dudit élément de conditionnement (15e) a été obtenue en pivotant de 180 degrés et en translatant ledit élément de conditionnement (15a) suivant ledit axe longitudinal (14a). La position de chaque élément de conditionnement (15f, 15g, 15h) est obtenue de manière analogue à partir de la position d'un élément de conditionnement respectif (15b, 15c, 15d). La translation de ladite deuxième demi-disposition par rapport à ladite première demi-disposition est réalisée sur une distance (20). Dans l'exemple représenté à la figure 3, ladite distance de translation (20) correspond sensiblement à la moitié de ladite distance de décalage (17). La répartition des huit éléments de conditionnement (15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h) constituant cet exemple de disposition élémentaire est ainsi sensiblement uniforme suivant ledit axe longitudinal (14a). La figure 4 représente un exemple de disposition élémentaire où 5V est impair. Plus précisément, 5V est ici égale à cinq. Lesdits éléments de conditionnement (15) sont donc répartis sur dix rangées, chaque rangée étant décalée angulairement de 36 degrés. Les cinq éléments de conditionnement (15a, 15b, 15c, 15d, 15e) constituent ladite première demi-disposition. Lesdits éléments de conditionnement (15a, 15b, 15c, 15d, 15e) occupent chacun une rangée sur deux. Lesdits éléments de conditionnement (15a, 15b, 15c, 15d, 15e) sont donc répartis uniformément sur les 360 degrés dudit support (14). Lesdits éléments de conditionnement (15a, 15b, 15c, 15d, 15e) sont également décalés les uns par rapport aux autres suivant ledit axe longitudinal (14a). Cependant dans cet autre exemple de disposition élémentaire, la distance (17) vue suivant ledit axe longitudinal (14a) séparant deux éléments de conditionnement consécutifs (15a, 15b ; 15b, 15c ; 15c, 15d ; 15d, 15e) n'est pas constante. En effet le décalage entre lesdits éléments de conditionnement (15a, 15b) est, par exemple, plus important ici que le décalage entre lesdits éléments de conditionnement (15b, 15c). Les cinq éléments de conditionnement (15f, 15g, 15h, 15i, 15j) constituent ladite deuxième demi-disposition. La position dudit élément de conditionnement (15f) a été obtenue en pivotant de 180 degrés et en translatant ledit élément de conditionnement (15a) suivant ledit axe longitudinal (14a). La position de chaque élément de conditionnement (15g, 15h, 15i, 15j) est obtenue de manière analogue à partir de la position d'un élément de conditionnement respectif (15b, 15c, 15d, 15e). A la lumière de la figure 4, la répartition desdits éléments de conditionnement (15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h, 15i, 15j) n'est pas uniforme vue suivant ledit axe longitudinal (14a). Cette disposition élémentaire permet une concentration d'éléments de conditionnement (15) plus importante sur une zone donnée dudit rotor (12). D'une manière préférentielle, cette zone donnée dudit rotor (12) correspond à l'endroit où le flux de produit coupé provenant dudit dispositif de coupe (8) est plus important. La figure 5 représente par contre un exemple de rotor (12) conforme à la présente invention où lesdits éléments de conditionnement (15) sont répartis suivant plusieurs dispositions élémentaires. Afin de faciliter la description de cet 19b, 19c, 19d, 19e, 19f, 19g). Ledit rotor (12) comporte plus précisément quatre dispositions élémentaires. Les quatre dispositions élémentaires comporte chacune six rangées (18). 5Vest donc impair et sa valeur est trois. De plus, lesdites rangées (18) d'une disposition élémentaire sont alignées avec lesdites rangées (18) de la disposition élémentaire voisine. Selon un autre exemple de réalisation non représenté, lesdites dispositions élémentaires ont un nombre de rangées (18) différent les une des autres. Le troisième tronçon (19c) dudit rotor (12) comporte des éléments de conditionnement (15) formant une première disposition élémentaire. Le cinquième tronçon (19e) dudit rotor (12) comporte des éléments de conditionnement (15) formant une deuxième disposition élémentaire. Ladite première disposition élémentaire et ladite deuxième disposition élémentaire sont semblables. Pour sa part, le quatrième tronçon (19d) dudit rotor (12) comporte des éléments de conditionnement (15) formant une troisième disposition élémentaire. La quatrième disposition élémentaire est par contre répartie sur le deuxième tronçon (19b) et sur le sixième tronçon (19f). En effet, ledit deuxième tronçon (19b) comporte des éléments de conditionnement (15) formant la première demi- disposition et ledit sixième tronçon (19f) comporte des éléments de conditionnement (15) formant la deuxième demi-disposition. Dans cet exemple de réalisation, ledit rotor (12) comporte encore des éléments de conditionnement (15) qui ne sont pas répartis suivant une disposition élémentaire. Tel est le cas des éléments de conditionnent (15) situés dans le premier tronçon (19a) et dans le dernier tronçon (19g). D'une manière préférentielle, lesdits éléments de conditionnement (15) de la première et de la deuxième disposition élémentaire sont différents des éléments de conditionnement (15) de la troisième et de la quatrième disposition élémentaire. A la lumière de la figure 2, cette différence peut apparaître sur la longueur desdits éléments de conditionnement (15). Diverses modifications peuvent être apportées aux exemples de réalisation qui viennent d'être décrits, notamment en ce qui concerne la constitution des divers éléments ou par substitution d'équivalents techniques, sans pour autant sortir du domaine de protection tel que défini par les revendications. (18) is therefore 45 degrees here. Said rows (18) extend in a direction parallel to said longitudinal axis (14a) of said support (14). In an elementary arrangement, said conditioning elements (15) are additionally offset with respect to each other along said longitudinal axis (14a). Thus during the rotation of said rotor (12), one never finds two conditioning elements (15) exactly in the extension of one another. Without departing from the scope of the present invention, the value of the offset may be less than the width of a conditioning element (15) so as to have a partial overlap of said conditioning elements (15). According to an important characteristic of the present invention, said elementary arrangement comprises 25V rows, 5V being even, and said elementary arrangement consists of: - a first half-arrangement of 25 conditioning elements (15), seen along said radial plane, said 25V conditioning elements (15) are distributed uniformly over the entire periphery of said support (14), and - a second half-arrangement of 25V conditioning elements (15), said second half-arrangement being obtained by a 180 degree rotation of said first half-arrangement around said longitudinal axis (14a), and by a translation along said longitudinal axis (14a). According to a variant of the present invention, said elementary arrangement comprises 25V rows, 5V being odd, and said elementary arrangement consists of: - a first half-arrangement of 5V conditioning elements (15), seen along said radial nlan, said 5V conditioning elements Cl 5) are distributed uniformly over the entire periphery of said support (14), and - a second half-arrangement of 5V conditioning elements (15), said second half-arrangement being obtained by a 180 degree rotation of said first half-arrangement around said longitudinal axis (14a), and by a translation along said longitudinal axis (14a). FIG. 3 represents an example of an elementary arrangement where 5V is even. More precisely, 5V is here equal to two. Said conditioning elements (15) are therefore distributed in four rows (18a, 18b, 18c, 18d), each row (18a, 18b, 18c, 18d) being angularly offset by 90 degrees. The four packaging elements (15a, 15b, 15c, 15d) constitute said first half arrangement. Said conditioning elements (15a, 15b, 15c, 15d) each occupy a respective row (18a, 18b, 18c, 18d). Said conditioning elements (15a, 15b, 15c, 15d) are therefore distributed uniformly over the 360 degrees of said support (14). In said first half-arrangement, said conditioning elements (15a, 15b, 15c, 15d) are offset from each other along said longitudinal axis (14a) by a constant offset distance (17). The four packaging elements (15th, 15f, 15g, 15h) constitute said second half-arrangement. The position of said conditioning element (15e) was obtained by pivoting 180 degrees and by translating said conditioning element (15a) along said longitudinal axis (14a). The position of each conditioning element (15f, 15g, 15h) is obtained in a similar manner from the position of a respective conditioning element (15b, 15c, 15d). The translation of said second half-disposition relative to said first half-disposition is carried out over a distance (20). In the example shown in Figure 3, said translation distance (20) corresponds substantially to half of said offset distance (17). The distribution of the eight packaging elements (15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h) constituting this example of elementary arrangement is thus substantially uniform along said longitudinal axis (14a). FIG. 4 represents an example of an elementary arrangement where 5V is odd. More precisely, 5V is here equal to five. Said conditioning elements (15) are therefore distributed over ten rows, each row being angularly offset by 36 degrees. The five packaging elements (15a, 15b, 15c, 15d, 15e) constitute said first half-arrangement. Said conditioning elements (15a, 15b, 15c, 15d, 15e) each occupy every other row. Said conditioning elements (15a, 15b, 15c, 15d, 15e) are therefore distributed uniformly over the 360 degrees of said support (14). Said conditioning elements (15a, 15b, 15c, 15d, 15e) are also offset with respect to each other along said longitudinal axis (14a). However in this other example of elementary arrangement, the distance (17) seen along said longitudinal axis (14a) separating two consecutive conditioning elements (15a, 15b; 15b, 15c; 15c, 15d; 15d, 15e) is not constant . Indeed, the offset between said packaging elements (15a, 15b) is, for example, greater here than the offset between said packaging elements (15b, 15c). The five packaging elements (15f, 15g, 15h, 15i, 15d) constitute said second half-arrangement. The position of said conditioning element (15f) was obtained by pivoting 180 degrees and by translating said conditioning element (15a) along said longitudinal axis (14a). The position of each conditioning element (15g, 15h, 15i, 15d) is obtained in a similar manner from the position of a respective conditioning element (15b, 15c, 15d, 15e). In light of FIG. 4, the distribution of said conditioning elements (15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h, 15i, 15j) is not uniform seen along said longitudinal axis (14a). This elementary arrangement allows a greater concentration of conditioning elements (15) in a given area of said rotor (12). Preferably, this given area of said rotor (12) corresponds to the place where the flow of cut product from said cutting device (8) is greater. FIG. 5, on the other hand, represents an example of a rotor (12) in accordance with the present invention where said conditioning elements (15) are distributed in several elementary arrangements. In order to facilitate the description of this 19b, 19c, 19d, 19th, 19f, 19g). Said rotor (12) more precisely comprises four elementary arrangements. The four elementary arrangements each have six rows (18). 5V is therefore odd and its value is three. In addition, said rows (18) of an elementary arrangement are aligned with said rows (18) of the neighboring elementary arrangement. According to another embodiment not shown, said elementary arrangements have a number of rows (18) different from one another. The third section (19c) of said rotor (12) comprises conditioning elements (15) forming a first elementary arrangement. The fifth section (19th) of said rotor (12) comprises conditioning elements (15) forming a second elementary arrangement. Said first elementary arrangement and said second elementary arrangement are similar. For its part, the fourth section (19d) of said rotor (12) comprises conditioning elements (15) forming a third elementary arrangement. The fourth elementary arrangement is however distributed over the second section (19b) and over the sixth section (19f). Indeed, said second section (19b) comprises packaging elements (15) forming the first half-arrangement and said sixth section (19f) comprises packaging elements (15) forming the second half-arrangement. In this exemplary embodiment, said rotor (12) also includes conditioning elements (15) which are not distributed in an elementary arrangement. This is the case of the conditioning elements (15) located in the first section (19a) and in the last section (19g). Preferably, said conditioning elements (15) of the first and second elementary arrangement are different from the conditioning elements (15) of the third and fourth elementary arrangement. In the light of FIG. 2, this difference may appear over the length of said packaging elements (15). Various modifications can be made to the exemplary embodiments which have just been described, in particular as regards the constitution of the various elements or by substitution of technical equivalents, without however departing from the field of protection as defined by the claims.
