Description

APPAREIL DISTRIBUTEUR DE MATERIAU DΕSSUYAGE AVEC DISPOSITIF DE COUPE INTEGRANT UNE CAPACITE DE SELECTION DE FORMAT.DISPENSING MACHINE FOR DISCHARGING MATERIAL WITH CUTTING DEVICE INCORPORATING FORMAT SELECTION CAPABILITY.
L'invention se rattache au secteur technique des appareils distributeurs à coupe automatique de matériaux d'essuyage du type papier ouaté pour des applications essuie-mains, papier toilette, essuyage et nettoyage en général.The invention relates to the technical sector of dispensing machines with automatic cutting of wiping paper-type wiping materials for towel, toilet paper, wiping and cleaning applications in general.
Le Demandeur a développé de nombreux appareils de ce type qui comprennent, de manière usuelle, un carter, un capot, un tambour avec lame de coupe intégrée, ladite lame étant susceptible de sortir du tambour en fonctionnement grâce à des moyens de lancement et de rappel du tambour. Des flasques latéraux du carter sont agencés pour supporter la bobine de matériau qui vient, soit en appui direct sur le tambour, selon l'enseignement du brevet FR 2.322.215, soit dans un plan au-dessus du tambour sans contact avec celui-ci, comme par exemple dans la réalisation décrite dans le brevet FR 2.799.946. Dans cette mise en œuvre spécifique, un rouleau presseur est susceptible d'assurer une pression de la bande de matériau à un endroit donné en complément d'une seconde zone de pression définie vers la zone de coupe de la bande de matériau au niveau du tambour. Ainsi, la bobine de chargement peut être montée soit en appui sur le tambour récepteur du mécanisme de coupe, soit dans un plan au-dessus du tambour et sans contact avec ce dernier. Ces différents types d'appareils dans leur concept de base et avec différents aménagements sont largement exploités par le demandeur à travers le monde par le biais de ses licenciés.The Applicant has developed many devices of this type which comprise, in the usual manner, a housing, a hood, a drum with integrated cutting blade, said blade being able to exit the drum in operation by means of launching and recalling drum. Side flanges of the housing are arranged to support the coil of material that comes, either in direct support on the drum, according to the teaching of FR 2,322,215, or in a plane above the drum without contact therewith , as for example in the embodiment described in FR 2,799,946. In this specific implementation, a pressure roller is capable of ensuring pressure of the web of material at a given location in addition to a second defined pressure zone towards the cutting zone of the web of material at the drum. . Thus, the loading coil can be mounted either on the receiving drum of the cutting mechanism, or in a plane above the drum and without contact therewith. These different types of devices in their basic concept and with different layouts are widely exploited by the applicant throughout the world through its licensees.
Le Demandeur a ainsi développé un autre appareil distributeur à coupe automatique de matériau d'essuyage qui soit simplifié dans sa mise en œuvre et objet du brevet FR n° 2.828.084. Succinctement, l'appareil comprend un carter de base avec une face de fond et une face inférieure avec un couvercle, ledit carter recevant de manière démontable, par encliquetage, une cartouche définissant une structure porteuse comprenant deux flasques latéraux transversaux, une plaque de liaison disposée entre les flasques et une barre entretoise avant. Les flasques reçoivent, dans leur partie haute, des embouts supports de la bobine de matériau et, dans leur partie basse, deux tambours disposés côte à côte, sans contact direct entre eux, le premier tambour étant le tambour porte-lame, le second étant le tambour de renvoi, lesdits tambours étant agencés à l'une de leurs extrémités en regard pour recevoir des couronnes dentées permettant leur liaison et leur rotation l'un par rapport à l'autre. Le tambour porte-lame est agencé par ailleurs avec une troisième couronne dentée coopérant avec le mécanisme de lancement en rotation des tambours incluant une came fixe. Ce bras porte-lame du dispositif de coupe inclut une lame mobile qui coopère avec la came fixe précitée en définissant la trajectoire de la lame de coupe. Cet appareil spécifique inclut un gabarit pour assurer le réglage du format de la bande de matériau à distribuer, soit par un changement préalable de pignon, ou avec l'utilisation de pignon baladeur déplaçable pour coopérer selon la position avec telle ou telle roue dentée par un aménagement du tambour notamment. Ledit pignon baladeur est associé à un index débordant monté sur l'axe mobile support du pignon baladeur et pour être déplacé préalablement par l'opérateur. Ceci nécessite un réglage préalable du format par l'opérateur avec ouverture de l'appareil.The Applicant has thus developed another dispenser device with automatic cutting of wiping material that is simplified in its implementation. the work and object of FR Patent No. 2,828,084. Briefly, the apparatus comprises a base casing with a bottom face and a bottom face with a cover, said casing receiving in a detachable manner, snap-fastening, a cartridge defining a supporting structure comprising two lateral transverse flanges, a connecting plate arranged between the flanges and a front spacer bar. The flanges receive, in their upper part, support ends of the material reel and, in their lower part, two drums arranged side by side, with no direct contact between them, the first drum being the blade drum, the second being the return drum, said drums being arranged at one of their ends facing to receive toothed rings for their connection and their rotation relative to each other. The blade drum is furthermore provided with a third ring gear cooperating with the mechanism for rotating the drums including a fixed cam. This blade holder arm of the cutting device includes a movable blade which cooperates with the aforementioned fixed cam by defining the path of the cutting blade. This specific apparatus includes a template for adjusting the format of the web of material to be dispensed, either by a prior change of pinion, or with the use of a sliding pinion that can be displaced in order to cooperate according to the position with a particular toothed wheel by a Drum arrangement in particular. Said sliding pinion is associated with an index protruding mounted on the movable shaft support sliding pinion and to be moved beforehand by the operator. This requires a prior adjustment of the format by the operator with opening of the device.
Dans toutes les réalisations développées par le Demandeur à ce jour, le dispositif de coupe est indépendant des aménagements et mécanismes permettant la sélection de format. Dans le cadre de ses recherches personnelles, le Demandeur a voulu améliorer la sortie de la lame de coupe hors du tambour avec un fonctionnement en douceur, pouvant être adapté sur tout type d'appareil distributeur rappelé précédemment.In all the embodiments developed by the Applicant to date, the cutting device is independent of the arrangements and mechanisms for selecting the format. As part of his personal research, the Applicant wanted to improve the output of the cutting blade out of the drum with a smooth operation, which can be adapted to any type of dispensing machine recalled above.
Un autre but recherché selon l'invention a été d'incorporer un dispositif sélecteur de format complémentaire au dit dispositif de coupe, qui soit de construction simplifiée, avec un rr nimum de pièces, et d'une facilité de réglage pour l'opérateur.Another object of the invention has been to incorporate a format selector device complementary to said cutting device, which is of simplified construction, with a rr nimum of parts, and an ease of adjustment for the operator.
Le but recherché par le Demandeur a ainsi été d'apporter des améliorations sur le dispositif de coupe et sur le dispositif de sélection de format qui puisse s'intégrer d'une manière optimisée dans les appareils existants.The aim sought by the Applicant has thus been to make improvements on the cutting device and on the format selection device which can be integrated in an optimized manner into existing devices.

Un ressort (8) assure la retenue élastique du porte-lame en étant fixé par une extrémité au moyeu central (5c) du tambour et à l'autre sur ledit porte-lame.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings. The dispensing apparatus is referenced as a whole by (1) and comprises a casing (2) having side flanges (3) (4) supporting the drum (5) including a cutting device on the one hand, and the coil of material (7) on the other hand. In a known manner, the drum whose end axes (5a) are positioned in the flanges (3) (4), has a longitudinal indentation (5b) capable of receiving the blade carrier (6) ( 6a), and this, in an articulated manner. A spring (8) ensures the elastic retention of the blade holder being fixed at one end to the central hub (5c) of the drum and to the other on said blade holder.
Selon l'invention, l'un des côtés transversaux (5d) du tambour (5) présente dans son prolongement une plaque support (10) obtenue par moulage avec la structure dudit tambour et étant déportée par rapport au dit côté latéral (5d). La plaque support présente une ouverture (10a) pour la fixation de l'extrémité (6b) du porte-lame (6). Sur ladite extrémité de ce dernier, est monté un secteur denté (11) établi selon une angulation d'environ 70 à 80° et présentant en extrémité périphérique une pluralité de dents (lia). Ces dents sont susceptibles de coopérer avec une roue dentée (12) montée libre et sous-jacente sur l'axe (5a) du tambour pour permettre ainsi qu'il sera exposé par la suite la sortie de lame de coupe. Ladite roue dentée (12) est solidarisée à une came crochet (13) qui tourne avec cette dernière lors du fonctionnement en rotation du tambour. L'extrémité de l'axe du tambour (5a) reçoit par ailleurs une roue dentée (14) de petit diamètre se prolongeant par une portée de fixation (14a). Parallèlement, le flasque (4) support de l'axe de guidage (5a) précité est lui-même agencé avec une échancrure (4a) pour le positionnement et l'appui de l'axe du tambour. Le tambour (5) présente en plus sur sa face latérale externe (5d) une forme en saillie (15) avec un profil en rampe (15a), cette forme étant solidarisée ou conformée lors du moulage. Le flasque (4) reçoit dans sa partie haute d'une manière rapportée ou monobloc, deux formes fixes constituant butées (16) (17) entre lesquelles est positionné un corps (18) profilé qui est fixé dans sa partie basse par un axe de liaison et de pivotement (19) disposé entre les deux butées précitées. Ce corps est conformé pour avoir une capacité élastique de déformation dans les conditions qui seront définies ci-après. Ce corps comprend une base centrale (18a) allongée dont l'extrémité supérieure (18b) présente un appendice (18c) conformé en L ou en crochet et formant tête, et qui vient se positionner en regard du chant (4c) du flasque (4) en regard, et en léger débordement intérieur par rapport au dit flasque (4). A partir de sa base (18a), le corps (18) présente une languette flexible (18d) dont l'extrémité arrière vient en appui sur la butée (17). Ainsi, ce corps est susceptible d'être sollicité en basculement grâce à sa capacité élastique de déformation et par rapport à son point de fixation et d'articulation (19) sur le flasque (4). Par ailleurs, la partie inférieure (18e) de la tête de ce corps constitue une zone de guidage et de butée par un décrochement (18f) dont la fonction sera précisée par la suite.According to the invention, one of the transverse sides (5d) of the drum (5) has in its extension a support plate (10) obtained by molding with the structure of said drum and being offset with respect to said lateral side (5d). The support plate has an opening (10a) for fixing the end (6b) of the blade holder (6). On said end of the latter, is mounted a toothed sector (11) established at an angle of about 70 to 80 ° and having at the peripheral end a plurality of teeth (11a). These teeth are capable of cooperating with a toothed wheel (12) freely mounted and underlying on the axis (5a) of the drum to thereby allow it to be exposed thereafter the cutting blade outlet. Said toothed wheel (12) is secured to a hook cam (13) which rotates with the latter during operation in rotation of the drum. The end of the axis of the drum (5a) also receives a toothed wheel (14) of small diameter extending by a fixing surface (14a). Meanwhile, the flange (4) support of the aforementioned guide pin (5a) is itself arranged with a notch (4a) for the positioning and support of the axis of the drum. The drum (5) additionally has on its outer lateral face (5d) a protruding shape (15) with a ramp profile (15a), this shape being secured or shaped during molding. The flange (4) receives in its upper part in an attached manner or one-piece, two fixed forms constituting abutments (16) (17) between which is positioned a shaped body (18) which is fixed in its lower part by an axis of link and pivoting (19) disposed between the two abovementioned abutments. This body is shaped to have an elastic capacity of deformation under the conditions that will be defined below. This body comprises an elongate central base (18a) whose upper end (18b) has an appendix (18c) shaped L or hook and forming a head, and which is positioned opposite the edge (4c) of the flange (4). ) facing, and slightly inward overflow relative to said flange (4). From its base (18a), the body (18) has a flexible tongue (18d) whose rear end abuts the abutment (17). Thus, this body is likely to be biased in tilting due to its elastic deformation capacity and relative to its point of attachment and articulation (19) on the flange (4). Moreover, the lower part (18e) of the head of this body constitutes a guiding and abutment zone by a recess (18f) whose function will be specified later.
Selon une autre disposition de l'invention, la partie inférieure (4d) du flasque (4) est susceptible de recevoir un levier coudé (20) qui est monté pivotant par rapport à un axe d'articulation (26) solidarisé au flasque (4) en regard. Ce levier (20) est conformé d'une manière très particulière de part et d'autre de son axe d'articulation. A l'avant, il présente un décrochement (20a) profilé en L, de manière à définir une forme en trident (20b). Cette dernière comprend ainsi deux dents extérieures (20b 1) (20b2) entre lesquelles est formée une languette flexible (20b3). L'espace (e) formé entre la dent (20cl) et la languette flexible (20b3) est susceptible d'accueillir un axe profilé (21a) en saillie d'un bouton sélecteur (21) de format. Cette partie profilée (21a) présente un méplat (21b) dont la fonction sera décrite par la suite. Le bouton sélecteur est fixé par vis (27) au flasque (4) de la partie en repère (25). A son extrémité opposée, le levier coudé (20) est susceptible de recevoir par un axe de liaison (22) une roue dentée (23) qui sera susceptible d'engrener avec la roue dentée (14) sous-jacente montée sur l'axe (5a) du tambour (5). La roue dentée (23) reçoit sur sa face (23a) en regard de la paroi du flasque un bossage (24) en saillie formant doigt dont la fonction sera décrite par la suite.According to another embodiment of the invention, the lower part (4d) of the flange (4) is capable of receiving a bent lever (20) which is pivotally mounted relative to a hinge pin (26) secured to the flange (4). ) opposite. This lever (20) is shaped in a very particular way on either side of its axis of articulation. At the front, it has a recess (20a) L-shaped, so as to define a trident shape (20b). The latter thus comprises two outer teeth (20b 1) (20b2) between which is formed a flexible tongue (20b3). The space (e) formed between the tooth (20cl) and the flexible tongue (20b3) is capable of accommodating a shaped axis (21a) projecting from a selector knob (21) of format. This profiled portion (21a) has a flat (21b) whose function will be described later. The selector knob is fixed by screws (27) to the flange (4) of the reference part (25). At its opposite end, the bent lever (20) is capable of receiving by a connecting pin (22) a toothed wheel (23) which will be capable of meshing with the gear wheel (14) underlying mounted on the axis (5a) of the drum (5). The toothed wheel (23) receives on its face (23a) facing the wall of the flange a projection (24) projecting finger forming whose function will be described later.
Le bouton sélecteur présente avantageusement un repère (25) permettant d'identifier sa position selon les deux modes de distribution de petit et de grand format.The selector knob advantageously has a marker (25) for identifying its position according to the two modes of small and large format distribution.
La structure de l'invention ayant été décrite, il convient maintenant de procéder à la description du fonctionnement du dispositif de coupe lorsque celui-ci est sollicité pour découper des bandes de matériau dans un premier format, par exemple 20 à 25 cm, ou selon un format plus important double du précédent 40 à 50 cm. On se réfère ainsi aux dessins pour exposer les deux phases de fonctionnement.The structure of the invention having been described, it is now advisable to describe the operation of the cutting device when the latter is urged to cut strips of material in a first format, for example 20 to 25 cm, or according to a larger double format from the previous 40 to 50 cm. The drawings are thus referred to to expose the two phases of operation.
A) Distribution et coupe d'une bande de matériau selon le petit format (20 à 25 cm)A) Distribution and cutting of a strip of material according to the small format (20 to 25 cm)
Dans cette situation, le bouton sélecteur (21) se trouve dans une situation telle entre la dent (20b 1) et la languette flexible (20b3) de sorte que sa partie méplate (21b) soit en regard de la paroi de la languette. Dans cette situation, ledit levier coudé (20) dans sa partie basse, réceptive de la roue (23), se trouve éloigné du corps (18) précité solidaire du flasque (4) et disposé dans un plan adjacent. Dans cette situation, l'opération de coupe s'effectue de la manière suivante.In this situation, the selector knob (21) is in such a situation between the tooth (20b 1) and the flexible tongue (20b3) so that its flat portion (21b) is facing the wall of the tongue. In this situation, said bent lever (20) in its lower part, receptive to the wheel (23), is located away from the aforementioned body (18) integral with the flange (4) and arranged in an adjacent plane. In this situation, the cutting operation is carried out as follows.
En phase initiale, le tambour (5) en position repos fait que la lame de coupe est escamotée sensiblement à l'intérieur du tambour. Le secteur denté (11) engrène avec la roue dentée (12) montée sur l'axe (5a) du tambour près de son côté latéral associé à la came crochet (13). Dans cette situation, ce sont ces dents (lia) situées à une extrémité du secteur qui sont en contact avec la roue dentée (12). De l'autre côté du flasque, la roue dentée (23) associée au levier coudé (20) engrène avec la roue dentée (14) montée sur l'axe (5a) du tambour (5). Le corps (18) à débattement élastique n'est pas sollicité. Lors de la traction de la bande de matériau par l'opérateur, le tambour est mis en rotation vers l'arrière et seule la roue dentée (12) et la came crochet (13) associée tournent. Le secteur denté (11) n'est soumis à aucun mouvement pour l'instant autour de la roue dentée (12) en regard. La came crochet (13) vient en butée et contact contre la tête du corps flexible (20), et son décrochement en particulier (18f) assurant ainsi un blocage en position. Dans cette situation, sous l'effet de tirage de la bande de matériau, le secteur denté (11) associé au tambour (5) est amené à tourner autour de la roue dentée (12) qui est bloquée en position de part la liaison de la came crochet avec la tête du corps précité. Cela provoque la sortie de la lame de coupe hors du tambour. La rotation continue du tambour amène la forme en saillie (15) qui est solidaire de son côté latéral (5c) à venir à son tour en contact avec la tête flexible du corps (20) et provoquer, en passant dessous, son soulèvement par la capacité élastique de déformation et de relevage de ladite tête. Ce soulèvement se fait grâce à la flexibilité à l'encontre de la languette inférieure dudit corps. Le soulèvement de la tête libère la came crochet (13) qui peut donc basculer avec la roue dentée (12) et revenir en position initiale par l'effet de détente du ressort (8) qui rappelle le porte lame. Le soulèvement de la tête du corps s'effectue lorsque la lame de coupe est en sortie maximum. A chaque tour de tambour, il y a coupe d'une bande de matériau au format sélectionné.In the initial phase, the drum (5) in the rest position makes the cutting blade is retracted substantially inside the drum. The toothed sector (11) meshes with the toothed wheel (12) mounted on the axis (5a) of the drum near its lateral side associated with the hook cam (13). In this situation, it is these teeth (11a) located at one end of the sector that are in contact with the toothed wheel (12). On the other side of the flange, the toothed wheel (23) associated with the bent lever (20) meshes with the toothed wheel (14) mounted on the axis (5a) of the drum (5). The body (18) with elastic displacement is not stressed. When the web of material is pulled by the operator, the drum is rotated backward and only the gearwheel (12) and the associated hook cam (13) rotate. The toothed sector (11) is not subject to any movement for the moment around the toothed wheel (12) opposite. The hook cam (13) comes into abutment and contact against the head of the flexible body (20), and its recess in particular (18f) thereby ensuring a locking position. In this situation, under the pulling effect of the web of material, the toothed sector (11) associated with the drum (5) is rotated around the toothed wheel (12), which is locked in position by means of the link the cam hook with the head of the aforementioned body. This causes the cutting blade to come out of the drum. The continuous rotation of the drum causes the protruding form (15) which is integral with its lateral side (5c) to come in turn in contact with the flexible head of the body (20) and cause, passing underneath, its lifting by the elastic capacity of deformation and lifting of said head. This lifting is done thanks to the flexibility against the lower tongue of said body. The lifting of the head releases the cam hook (13) which can tilt with the toothed wheel (12) and return to the initial position by the triggering effect of the spring (8) which recalls the blade holder. The lifting of the head of the body takes place when the cutting blade is at the maximum output. Each drum revolution, there is cutting a strip of material in the selected format.
B) Distribution et coupe d'une bande de matériau selon le grand format (40 à 50 cm)B) Distribution and cutting of a band of material according to the large format (40 to 50 cm)
II convient maintenant d'exposer la variante de sélection de format. Dans cette mise en œuvre, il convient d'agir sur le bouton sélecteur (21) en le faisant tourner d'un demi tour, de sorte à supprimer le contact de la partie méplate (21b) de l'axe du bouton avec les faces en regard des dents du levier coudé (20). L'axe du bouton sélecteur étant de diamètre plus important, cela provoque l'écartement de la languette flexible (20b3) intermédiaire qui vient en contact et poussée sur la dent (20b2) située immédiatement derrière. Cela entraîne un léger pivotement du levier coudé (20) par rapport à son axe de rotation (26). En conséquence, la partie arrière du levier coudé est légèrement surélevée, de sorte à rapprocher le bossage (24) en saillie formant doigt de la roue dentée (23) associée à la partie arrière du levier vers la base inférieure du corps.It is now necessary to expose the format selection variant. In this implementation, it is necessary to act on the selector knob (21) by rotating it by half a turn, so as to remove the contact of the flattened portion (21b) of the axis of the button with the faces facing the teeth of the bent lever (20). The axis of the selector knob being of larger diameter, it causes the spacing of the intermediate flexible tongue (20b3) which comes in contact and pushed on the tooth (20b2) located immediately behind. This causes a slight pivoting of the bent lever (20) relative to its axis of rotation (26). Accordingly, the rear portion of the bent lever is slightly raised, so as to bring the projection (24) projecting finger of the toothed wheel (23) associated with the rear portion of the lever towards the lower base of the body.
Une fois le bouton sélecteur mis en position, il convient de décrire le fonctionnement de l'ensemble du dispositif en considérant ainsi la distribution d'une bande de matériau selon un double format. Pour arriver à cette fonction, cela nécessite que la lame de coupe n'intervienne qu'une fois sur deux. La démarche est donc la suivante. En phase initiale, le secteur denté se trouve en prise par ses dents (lia) avec la roue dentée (12). La traction de la bande de matériau provoque la rotation du tambour vers l'arrière et ainsi la rotation de la roue dentée (12) et de la came crochet (13) qui lui est associée. Cette dernière vient alors en butée contre la tête du corps (20) en provoquant son blocage en position avec la roue (12) associée. La rotation continue provoque le déplacement du secteur denté et du porte lame et donc la sortie de la lame. A cet instant, le bossage formant doigt formé sur la roue (23) se trouve à l'opposé de la face intérieure du corps (20). La rotation continue du tambour amène la forme en saillie (15) solidaire du côté latéral (5d) du tambour (5) à assurer le soulèvement de la tête du corps et la libération de la came crochet (13). La rotation à nouveau du tambour amène cette fois le bossage formant doigt, associé à la roue (23), à provoquer le soulèvement de la tête du corps (20), de sorte à échapper et empêcher tout contact avec la came crochet qui vient une nouvelle fois en regard de cette zone. Dans ces conditions, la came crochet n'est pas freinée et donc sa roue dentée (12) associée non plus, et il n'y a pas action en vue d'assurer la sortie de la lame de coupe. Cela permet, lorsque le bossage formant doigt a passé son point contact avec le corps, d'effectuer ensuite une seconde rotation du tambour, en vue, cette fois-ci, de la sortie de la lame de coupe. En effet, le bossage ne sera plus en contact avec le corps et la came crochet viendra cette fois-ci en contact avec la tête du corps, en entraînant le pivotement du secteur denté et donc la sortie de la lame de coupe puis la forme en saillie viendra soulever ladite tête du corps en libérant la came crochet et autoriser la sortie. Par cette disposition originale, on obtient la distribution d'une bande de matériau en double format. Les avantages ressortent bien de la description, en particulier on souligne et on rappelle la simplicité du mécanisme du dispositif, son adaptabilité immédiate par un opérateur au format choisi. Le Demandeur a constaté une grande douceur de fonctionnement du dispositif de coupe. Ainsi, par un nombre de pièces complémentaire limité, on peut assurer cette seconde fonction de sélection de format. Once the selector button is in position, it is necessary to describe the operation of the entire device, thus considering the distribution of a strip of material in a double format. To achieve this function, it requires that the cutting blade intervenes only once in two. The approach is therefore the following. In the initial phase, the toothed sector is engaged by its teeth (11a) with the toothed wheel (12). Traction of the web of material causes the drum to rotate rearwardly and thus the rotation of the gearwheel (12) and the hook cam (13) associated therewith. The latter then comes into abutment against the head of the body (20) causing its locking in position with the wheel (12) associated. The continuous rotation causes the displacement of the toothed sector and the blade holder and therefore the exit of the blade. At this time, the finger-shaped boss formed on the wheel (23) is opposite the inner face of the body (20). The continuous rotation of the drum causes the protruding form (15) integral with the lateral side (5d) of the drum (5) to ensure the lifting of the head of the body and the release of the hook cam (13). The rotation of the drum again brings this time the finger boss, associated with the wheel (23), to cause the lifting of the head of the body (20), so as to escape and prevent contact with the hook cam which comes a again next to this area. Under these conditions, the hook cam is not braked and therefore its toothed wheel (12) associated either, and there is no action to ensure the output of the cutting blade. This allows, when the finger boss has passed its point of contact with the body, to then perform a second rotation of the drum, in view, this time, the output of the cutting blade. Indeed, the boss will no longer be in contact with the body and the hook cam comes this time in contact with the head of the body, causing the pivoting of the toothed sector and thus the output of the cutting blade and the shape in protrusion will lift said head of the body by releasing the cam hook and allow the exit. By this original arrangement, the distribution of a strip of material in double format is obtained. The advantages are apparent from the description, in particular emphasizes and reminds the simplicity of the mechanism of the device, its immediate adaptability by an operator in the chosen format. The Applicant has found a great smooth operation of the cutting device. Thus, by a limited number of complementary parts, it is possible to provide this second format selection function.
