Abstract

Improved cutting device for an apparatus for the simultaneous dispensing and cutting of bands of wound material. This device is distinguished in that it comprises two independent blades located side by side at an angle, each of which corresponds to two half-lengths of the drum, whereby each of the blades is fixed to blade carriers oriented angularly in the drum and is associated with a follower roller which cooperates respectively with a fixed cam of the same profile located on each lateral wing of the housing of the apparatus, whereby said cams are offset angularly in order to permit the progressive and successive exiting of each blade and to define two cutting zones of the band of material in the apparatus while obtaining only a single clean cutting line of said material perpendicular to its lateral edges.

Description

L'objet de l'invention se rattache au secteur technique des moyens de distribution de longueur de matériaux enroulés sur des bobines. Notamment, mais non exclusivement l'invention s'applique aux appareils distributeurs de papier, ouate et matériaux similaires d'essuyage.The object of the invention relates to the technical sector of the means for distributing the length of materials wound on reels. In particular, but not exclusively, the invention applies to dispensers for paper, wadding and similar wiping materials.

L'appareil est non limitativement du type selon lequel le rouleau de matériau en service monté à rotation libre sur un support, est appliqué en pression directement sur un tambour à surface anti-glissante, afin que par simple traction manuelle sur la bande de matériau débordant de l'appareil on distribue et on coupe automatiquement une bande dont la longueur est sensiblement égale au diamètre du tambour, cela par un dispositif de coupe dentelé associé au tambour, et faisant saillie hors du tambour lorsqu'on l'entraine en rotation par traction sur le matériau, de manière à pénétrer dans le matériau ainsi tendu de part et d'autre du dispositif de coupe. Après la coupe, le tambour lancé revient à sa position initiale par l'intermédiaire de l'action de divers organes complémentaires, et une nouvelle bande de matériau déborde de l'appareil.The apparatus is not limited to the type according to which the roll of material in service mounted with free rotation on a support, is applied by pressure directly to a drum with non-slip surface, so that by simple manual pulling on the strip of overflowing material of the device, a strip is distributed and cut automatically, the length of which is substantially equal to the diameter of the drum, by a serrated cutting device associated with the drum, and protruding from the drum when it is rotated by traction on the material, so as to penetrate the material thus stretched on either side of the cutting device. After cutting, the launched drum returns to its initial position through the action of various complementary members, and a new strip of material overflows from the device.

Un tel dispositif de coupe a notamment été décrit dans le brevet français no 2.332.215 et dans le certificat d'addition no 2.340.887 appartenant au déposant. Le mode d'entrainement du dispositif de coupe, la rotation du tambour et les moyens de commande en déplacement, d'arrêt et de contrôle ont été décrits dans les brevets précités et également dans le brevet européen no 0157713 et dans les brevets français no 85.19447 et no 85.02873 au nom du déposant. D'autres moyens peuvent cependant être utilisés. Il apparait cependant important pour la bonne compréhension de l'invention de rappeler préalablement, à titre d'exemple non limitatif, les caractéristiques particulières du dispositif de coupe décrit dans les brevets précités, en se référant aux figures 1, 2, et 3 des dessins.Such a cutting device has in particular been described in the French patent No. 2.332.215 and in the Certificate of Addition No. 2,340,887 owned by the applicant. The drive mode of the cutting device, the drum rotates and the control means on the move, stop, and control have been described in the above patents and also in European Patent No. 0157713 and in French Patent n o 85.19447 and n o 85.02873 in the name of the depositor. Other means can however be used. However, it appears important for a good understanding of the invention to recall beforehand, by way of nonlimiting example, the particular characteristics of the cutting device described in the aforementioned patents, with reference to Figures 1, 2, and 3 of the drawings. .

Celles-ci illustrent schématiquement le déplacement de la lame de coupe. Le tambour (1) dont l'intérieur est creux permet par rapport à son axe de rotation une manoeuvre intérieure de la lame de coupe (2) par l'intermédiaire d'un galet (3) associé au porte lame (4) coopérant avec le contour d'un palier fixe (5) formant came et autour de celui-ci. Le palier par cette coopération assure un mouvement de distribution et un déplacement progressif de la lame (2), déterminé par la forme de la came afin de faire décrire par celle-ci à l'intérieur du tambour et simultanément avec la trajectoire de celui-ci et dans le même sens une trajectoire de cercle complet de 360 degrés depuis une position escamotée jusqu'à une position à proximité du plan de tangence par rapport à la bande de papier de manière qu'à la terminaison de la traction manuelle de la lame de coupe en passant à travers la fente dans le tambour, la lame fasse saillie en direction transversale dans cette bande, avec pénétration dans la bande de papier qui est tendue des deux côtés de la lame de coupe.These schematically illustrate the movement of the cutting blade. The drum (1) whose interior is hollow allows relative to its axis of rotation an internal operation of the cutting blade (2) by means of a roller (3) associated with the blade holder (4) cooperating with the outline of a fixed bearing (5) forming a cam and around it. The bearing by this cooperation ensures a movement of distribution and a progressive displacement of the blade (2), determined by the shape of the cam in order to make describe by this one inside the drum and simultaneously with the trajectory of this one. ci and in the same direction a full circle trajectory of 360 degrees from a retracted position to a position near the plane of tangency with respect to the strip of paper so that at the end of the manual pull of the blade cutting passing through the slot in the drum, the blade protrudes transversely in this strip, with penetration into the strip of paper which is stretched on both sides of the cutting blade.

L'appareil du type précité permet la découpe de longueurs de bandes de matériaux en ouate et matériaux similaires. Ce type d'appareil est exploité avec une grande fiabilité d'utilisation et son succès commercial confirme ses performances techniques.The apparatus of the aforementioned type allows the cutting of lengths of strips of wadding and similar materials. This type of device is operated with great reliability of use and its commercial success confirms its technical performance.

Il est apparu cependant intéressant pour certains types de produits d'essuyage très fins la nécessité d'adoucir l'effort de traction du dispositif de coupe lors de la découpe du papier. En effet, ces matériaux très fins provoquent en cours de traction avec les mains mouillées de l'utilisateur le déchirement du papier.It appeared however interesting for certain types of very fine wiping products the need to soften the tensile force of the cutting device during the cutting of the paper. Indeed, these very fine materials cause tearing of the paper during traction with the wet hands of the user.

Le but recherché selon l'invention était donc d'améliorer par exemple et de manière non limitative la conception de l'appareil pour résoudre ce besoin. En outre, l'invention vise un nouveau dispositif de coupe quels que soient les moyens complémentaires utilisés pour le contrôle de l'arrêt du tambour.The aim sought after according to the invention was therefore to improve, for example and without limitation, the design of the device to solve this need. In addition, the invention relates to a new cutting device whatever the additional means used for controlling the stopping of the drum.

Après différents essais et recherches effectués en relation avec la rotation du tambour, une solution a été trouvée offrant des résultats inattendus très performants en égard de la coupe de papier en matériaux notamment très fins. Cette solution réside dans un agencement différent de la lame de coupe et du dispositif de coupe en général selon un mode opératoire qui va à l'encontre du fonctionnement antérieur de ce dispositif tel que rappelé ci-avant, et de l'art antérieur en général dont a connaissance le déposant. Ce dispositif est adaptable pour les appareils simple rouleau, double rouleaux et d'une manière générale à tout appareil comprenant un rouleau de service et au moins un rouleau de réserve.After various tests and research carried out in In relation to the rotation of the drum, a solution has been found offering unexpected results which are very effective with regard to the cutting of paper into particularly very fine materials. This solution lies in a different arrangement of the cutting blade and of the cutting device in general according to an operating mode which goes against the prior operation of this device as recalled above, and of the prior art in general. of which the depositor is aware. This device is adaptable for single roller devices, double rollers and in general to any device comprising a service roller and at least one reserve roller.

Selon une première caractéristique, ce dispositif comprend un tambour creux intérieurement avec une fente longitudinale sur sa périphérie extérieure, et recevant une lame et support de lame de coupe articulé à l'encontre d'un moyen de rappel à l'intérieur du tambour, ladite lame faisant saillie extérieurement par la fente sous l'effet de rotation du tambour lorsqu'on l'entraine en rotation par traction sur le matériau de manière à pénétrer dans le matériau tendu de part et d'autre du dispositif de coupe, ladite lame se déplaçant selon une trajectoire donnée par un galet suiveur associé au porte lame et coopérant avec des mécanismes incluant notamment une came profilée fixe disposée sur la paroi latérale du carter de l'appareil agencé pour recevoir ledit tambour d'entrainement et un ou plusieurs rouleaux de réserve, ledit dispositif étant caractérisé en ce qu'il comprend deux lames indépendantes disposée cote à cote selon une angulation et correspondant chacune à une demi-longueur du tambour, lesdites lames fixées sur des portes-lames orientés angulairement dans le tambour, étant chacune associées à un galet suiveur coopérant respectivement avec une came fixe de même profil disposée sur chaque aile latérale du carter de l'appareil, lesdites cames étant décalées angulairement pour permettre la sortie progressive et successive de chacune des lames et définir deux zones de coupe de la bande de matériau à l'intérieur de l'appareil tout en obtenant qu'une seule ligne de coupe nette dudit matériau perpendiculaire à ses bords latéraux.According to a first characteristic, this device comprises an internally hollow drum with a longitudinal slot on its outer periphery, and receiving a blade and cutting blade support articulated against a return means inside the drum, said blade projecting externally through the slot under the effect of rotation of the drum when it is rotated by traction on the material so as to penetrate the material stretched on either side of the cutting device, said blade moving along a trajectory given by a follower roller associated with the blade holder and cooperating with mechanisms including in particular a fixed profiled cam disposed on the side wall of the casing of the device arranged to receive said drive drum and one or more reserve rollers , said device being characterized in that it comprises two independent blades arranged side by side at an angle and corresponding each at half a length of the drum, said blades fixed on blade holders angularly oriented in the drum, each being associated with a follower roller cooperating respectively with a fixed cam of the same profile disposed on each lateral wing of the casing of the device , said cams being angularly offset to allow the progressive and successive exit of each of the blades and define two cutting zones of the strip of material inside the device while obtaining only one clean cutting line of said material perpendicular to its lateral edges.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.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.

Le dispositif de coupe selon l'invention peut être utilisé avec tous types d'appareils à distribution de bandes de matériaux enroulés, à simple rouleau, double rouleaux, et plus généralement avec un rouleau de service et plusieurs rouleaux de réserve.The cutting device according to the invention can be used with all types of apparatus for distributing strips of wound material, with single roller, double rollers, and more generally with a service roller and several reserve rollers.

Le dispositif de coupe selon l'invention s'applique naturellement mais d'une manière non limitative aux différents appareils dont les caractéristiques ont été décrites et définies notamment dans les brevets précités. Il va de soi cependant que le dispositif de coupe selon l'invention peut dans son principe et sa fonction être utilisé avec d'autres appareils.The cutting device according to the invention applies naturally but in a nonlimiting manner to the various devices whose characteristics have been described and defined in particular in the aforementioned patents. It goes without saying, however, that the cutting device according to the invention can in principle and its function be used with other devices.

On a illustré une application non limitative du dispositif de coupe aux appareils GRANGER pour mettre en valeur le nouveau concept inventif.A non-limiting application of the cutting device to GRANGER devices has been illustrated to enhance the new inventive concept.

Préalablement, on rappelle succintement les éléments principaux de l'appareil GRANGER. Celui-ci comprend à partir d'un carter, une plaque de base (6) à fixation murale, des moyens support à rotation libre, un tambour d'entrainement (7) par rapport aux ailes latérales (6.1) (6.2) dudit carter. Le tambour reçoit a l'intérieur un porte-lame articulé sur une paroi latérale du tambour présentant à l'extérieur un galet suiveur (29) coopérant avec une came fixe (10) pour autoriser la sortie périodique de la lame de coupe dentelée en dehors du tambour, lorsqu'on tire sur la bande de matériau débordant sous l'appareil en entrainant ainsi en rotation le tambour à surface rugueuse sur lequel et appliqué le rouleau (R1) de matériau enroulé. Celui-ci est porté par un étrier-support (8) articulé sur la plaque de base. On voit encore un rouleau (11) selon une disposition décrite dans une autre demande, avec une courroie (12) associée également au tambour pour guider correctement le matériau vers l'ouverture inférieure et pour éviter l'introduction des doigts de l'utilisateur à proximité de la lame de coupe.Beforehand, we briefly recall the main elements of the GRANGER device. This comprises, from a housing, a base plate (6) for wall mounting, free rotation support means, a drive drum (7) relative to the lateral wings (6.1) (6.2) of said housing. . The drum receives inside a blade holder articulated on a side wall of the drum having on the outside a follower roller (29) cooperating with a fixed cam (10) to authorize the periodic exit of the serrated cutting blade outside of the drum, when the strip of material overflowing under the apparatus is pulled, thereby driving in rotation the drum with rough surface on which and applied the roll (R1) of wound material. This is carried by a support bracket (8) articulated on the base plate. We also see a roller (11) according to an arrangement described in another application, with a belt (12) also associated with the drum to correctly guide the material towards the lower opening and to avoid the introduction of the user's fingers to near the cutting blade.

En se référant à la figure 4 le carter comprend au niveau de la zone de positionnement du tambour, des dégagements intérieurs en U (6.3) formés sur les ailes latérales. On rappelle, succintement les principaux moyens autorisant le mouvement de sortie de la lame, les moyens étant disposés sur l'une des parois (6-1) du carter.Referring to FIG. 4, the casing includes, at the level of the positioning zone of the drum, clearances U-shaped interiors (6.3) formed on the side wings. It will be recalled, briefly, the main means allowing the blade to move out, the means being arranged on one of the walls (6-1) of the casing.

En se référant aux figures 4 et 6, ainsi que décrites dans les brevets, antérieurs précités, le parachute (13) est agencé pour recevoir successivement le plateau support (14) de came (10), la came (10) profilée autorisant le guidage du galet suiveur (29) monté sur le porte lame, le cliquet (16) avec son ressort de rappel (17).Referring to Figures 4 and 6, as described in the aforementioned prior patents, the parachute (13) is arranged to successively receive the cam support plate (14) (10), the profiled cam (10) authorizing the guiding of the follower roller (29) mounted on the blade holder, the pawl (16) with its return spring (17).

Il est illustré également une rampe fixe (15) curviligne d'environ 90 degrés et sur laquelle se déplace la butée mobile (18) montée sur le tambour ; la butée fixe disposée sur le tambour est référencée en (19). Cette rampe est disposée entre la came (10) et le cliquet et son orientation est établie pour permettre le guidage et l'appui de la butée mobile du tambour lors de la rotation de celui-ci. On a illustré également en (20) la butée anti-retour du parachute et en (21) le rouleau de guidage de l'extrémité libre de la bande de matériau. Le fonctionnement du mécanisme a été décrit dans les brevets antérieurs précités et il y a lieu de s'y référer.There is also illustrated a fixed ramp (15) curvilinear about 90 degrees and on which moves the movable stop (18) mounted on the drum; the fixed stop disposed on the drum is referenced in (19). This ramp is arranged between the cam (10) and the pawl and its orientation is established to allow the guide and the support of the mobile stop of the drum during the rotation of the latter. Also illustrated in (20) the non-return stop of the parachute and in (21) the guide roller of the free end of the strip of material. The operation of the mechanism has been described in the aforementioned prior patents and should be referred to.

Le dispositif de coupe intégré dans le tambour d'entrainement du matériau comprend selon l'invention deux lames (22-23) indépendantes disposées cote à cote et correspondant chacune à sensiblement une demi-longueur du tambour. Ainsi qu'il apparait figure 8, les deux lames ne sont pas disposées en alignement mais selon une angulation α d'environ 150 à 179 degrés et avantageusement de l'ordre de 170°. Ainsi les deux lames se trouvent disposées sensiblement dans un plan symétrique par rapport à l'axe médian transversal du tambour, et sont ainsi montées en regard. Leurs parties dentelées sont toutefois orientées du même côté. Chaque lame (22-23) est montée sur un porte-lame (24-25) en L articulé par son extrémité inférieure sur des axes (32-33) positionnés sur des blocs supports (26) formés à l'intérieur dudit tambour ; les blocs-supports d'une même lame étant décalés pour donner une orientation angulaire des lames (figures 7 et 8). Chaque porte-lame (24-25) est sollicité en position repos correspondant au retrait de lame à l'intérieur du tambour par un ressort de rappel (27) dont une extrémité (27.1) est fixée à la paroi du tambour. Par ailleurs, selon une autre disposition de l'invention, chaque lame ou porte-lame reçoit en bout en débordement extérieur de chaque paroi transversale du tambour, un galet (28-29) monté libre en rotation susceptible d'agir et coopérer avec des cames à position fixe disposées sur le carter de réception du tambour et de ses mécanismes complémentaires. Ainsi on comprend que chaque lame (22-23) possède un mouvement d'articulation qui lui est propre tout en étant similaire l'un de l'autre. De manière avantageuse, il est prévu que l'axe du tambour, l'axe de rotation des galets (28-29) et l'axe (32) d'articulation situé vers le côté latéral du tambour de chaque porte lame soient alignés, selon la ligne XX ou sensiblement, limitant les efforts de coupe. Selon une autre disposition particulièrement importante et complémentaire, les deux galets (28-29) précités coopèrent chacun avec une came fixe disposée sur le carter de l'appareil. Plus précisémment en se rapportant aux figures des dessins, une première came fixe est celle (10) fixée sur la première aile (6.1) du carter du côté du mécanisme d'arrêt et de verrouillage en position du tambour tel qu'illustré figure 6.The cutting device integrated in the material drive drum comprises according to the invention two independent blades (22-23) arranged side by side and each corresponding to substantially a half-length of the drum. As appears in Figure 8, the two blades are not arranged in alignment but at an angulation α of about 150 to 179 degrees and advantageously of the order of 170 °. Thus the two blades are arranged substantially in a plane symmetrical with respect to the transverse median axis of the drum, and are thus mounted opposite. Their serrated parts are however oriented on the same side. Each blade (22-23) is mounted on an L-shaped blade holder (24-25) articulated by its lower end on axes (32-33) positioned on support blocks (26) formed inside said drum; the support blocks of a same blade being offset to give an angular orientation of the blades (Figures 7 and 8). Each blade holder (24-25) is biased in the rest position corresponding to the blade removal inside the drum by a return spring (27), one end (27.1) of which is fixed to the wall of the drum. Furthermore, according to another arrangement of the invention, each blade or blade holder receives at the end in external overflow from each transverse wall of the drum, a roller (28-29) mounted free in rotation capable of acting and cooperating with fixed position cams arranged on the housing for receiving the drum and its complementary mechanisms. Thus it is understood that each blade (22-23) has its own articulation movement while being similar to each other. Advantageously, provision is made for the axis of the drum, the axis of rotation of the rollers (28-29) and the axis (32) of articulation situated towards the lateral side of the drum of each blade holder to be aligned, along the line XX or substantially, limiting the cutting forces. According to another particularly important and complementary arrangement, the two aforementioned rollers (28-29) each cooperate with a fixed cam disposed on the casing of the device. More precisely with reference to the figures of the drawings, a first fixed cam is that (10) fixed on the first wing (6.1) of the casing on the side of the stop and locking mechanism in position of the drum as illustrated in FIG. 6.

Une seconde came fixe (30) est rapportée et fixée sur la seconde aile (6.2) du carter à l'opposé de la précédente. Les deux cames (10) et (30) ont exactement le même profil périphérique de sorte que lorsque les galets suiveurs (28-29) associés aux porte-lames (24-25) les contournent le long de leur périphérie extérieure, les trajectoires des deux lames sont exactement les mêmes.A second fixed cam (30) is attached and fixed to the second wing (6.2) of the casing opposite to the previous one. The two cams (10) and (30) have exactly the same peripheral profile so that when the follower rollers (28-29) associated with the blade holders (24-25) bypass them along their outer periphery, the trajectories of the two blades are exactly the same.

Cependant et selon une disposition essentielle de l'invention contribuant au bon fonctionnement du dispositif de coupe pris dans son ensemble, les deux cames (10) et (30) ont une orientation angulaire différente de sorte qu'il se produit un décalage dans leur sortie lors du mouvement de rotation du tambour d'entrainement. Leur disposition définit une orientation angulaire différente de l'ordre de 80 à 100 degrés environ de telle sorte qu'il y ait une continuité dans la pénétration des deux lames dans la bande de matériaux à découper. Plus spécifiquement, ainsi qu'il apparait de manière schématique aux figures 10 à 13, le décalage angulaire des deux cames (10-30) permet d'obtenir d'abord la pénétration dans le matériau d'essuyage d'une lame (22) sur une demi-largeur, puis de l'autre lame (23) sur la seconde demi-largeur avant le retrait de la première lame.However and according to an essential arrangement of the invention contributing to the proper functioning of the cutting device taken as a whole, the two cams (10) and (30) have a different angular orientation so that it occurs an offset in their output during the rotational movement of the drive drum. Their arrangement defines a different angular orientation of the order of about 80 to 100 degrees so that there is continuity in the penetration of the two blades in the strip of material to be cut. More specifically, as appears schematically in FIGS. 10 to 13, the angular offset of the two cams (10-30) makes it possible first to obtain penetration into the wiping material of a blade (22) on a half-width, then of the other blade (23) on the second half-width before the withdrawal of the first blade.

Selon une autre disposition intéressante, la sortie des dentures de chaque lame est progressive en ce sens qu'au fur et à mesure de la rotation du tambour et de la sortie successive des lames, ce sont les dents situées vers l'extérieur du tambour qui sortent les premières puis les autres en se rapprochant au fur et à mesure de la partie centrale du matériau. Ainsi la profondeur de sortie des différentes dents de chaque lame varie sensiblement, la sortie étant maximum pour la dent la plus proche de l'extrémité latérale du tambour. Par ailleurs, la fente (31) formée sur le tambour par laquelle passent les lames est découpée selon un profil en V complémentaire au profil et disposition des lames. On a donc deux zones de coupe différentes de la bande de papier par rapport à son rouleau de distribution et le tambour d'entrainement, l'une se situant sensiblement telle qu'illustrée figure 10, tout de suite après le plan de contact du rouleau de papier et du tambour d'entrainement (ZCI, zone de coupe 1), et l'autre dans la partie arrière basse du tambour d'entrainement illustrée par la référence (ZC2, zone de coupe 2).According to another interesting arrangement, the output of the teeth of each blade is progressive in the sense that as the rotation of the drum and the successive output of the blades, it is the teeth located towards the outside of the drum which come out first and then the others, gradually approaching the central part of the material. Thus, the outlet depth of the different teeth of each blade varies significantly, the outlet being maximum for the tooth closest to the lateral end of the drum. Furthermore, the slot (31) formed on the drum through which the blades pass is cut according to a V-profile complementary to the profile and arrangement of the blades. There are therefore two different cutting zones of the paper strip with respect to its dispensing roller and the drive drum, one being located substantially as illustrated in FIG. 10, immediately after the contact plane of the roller. of paper and of the drive drum (ZCI, cutting area 1), and the other in the lower rear part of the drive drum illustrated by the reference (ZC2, cutting area 2).

La coupe s'effectue le long d'une ligne continue horizontale de la bande de matériau. Par ailleurs, on voit selon les figures 10 à 13 à caractère schématique que la dernière dent de la première lame située le plus au centre du tambour, amorce une découpe en V correspondant au profil de la dent et la dernière dent de la seconde lame située le plus au centre du tambour amorce une autre découpe en V adjacente à celle précitée, une bande infime de papier assurant la liaison entre elles. Sous l'effet continu de traction de la bande de matériau par l'utilisateur, ladite bande de liaison se déchire également séparant de manière définitive le morceau de papier tiré. La coupe du matériau selon le dispositif précité s'effectue par déchirement de la bande de papier avec une action progressive. Il y à lieu de bien mettre en évidence le fait que l'inclinaison des lames de coupe dans deux plans, d'une part par rapport à l'axe longitudinal du tambour ou de sa génératrice extérieure et d'autre part des dentures de chaque lame en profondeur en allant vers la partie médiane du tambour, combinée avec les profils des cames, permet une coupe de la bande de papier, droite, nette et sans raccord perpendiculairement aux côtés de la bande.The cut is made along a continuous horizontal line of the strip of material. Furthermore, we see according to Figures 10 to 13 schematically that the last tooth of the first blade located most in the center of the drum, initiates a V-shaped cut corresponding to the profile of the tooth and the last tooth of the second blade located most in the center of the drum initiates another V cut adjacent to the above, a tiny strip of paper ensuring the connection between them. Under the continuous pulling effect of the strip of material by the user, said connecting strip also tears definitively separating the piece of pulled paper. The material is cut according to the above-mentioned device by tearing the paper strip with a progressive action. It should be made clear that the inclination of the cutting blades in two planes, on the one hand with respect to the longitudinal axis of the drum or its external generatrix and on the other hand the teeth of each blade in depth going towards the middle of the drum, combined with the profiles of the cams, allows a cut of the paper strip, straight, clean and without connection perpendicular to the sides of the strip.

L'obtention du résultat à savoir la qualité de la coupe et sa netteté exige un positionnement particulièrement précis des différents moyens constitutifs du dispositif de coupe. Il y a lieu notamment de souligner que la première lame (22) pénètre dans le matériau par un mouvement d'articulation donnée selon la flèche F1 inverse au sens de déroulement F2 du tambour ce qui accentue l'effet de déchirement avec moins d'effort. La seconde lame (23) pénètre elle dans le même sens que le sens de déroulement du tambour.Obtaining the result, namely the quality of the cut and its sharpness, requires particularly precise positioning of the various means constituting the cutting device. It should in particular be emphasized that the first blade (22) penetrates into the material by a hinge movement given according to the arrow F1 opposite to the direction of unwinding F2 of the drum, which accentuates the tearing effect with less effort. . The second blade (23) penetrates in the same direction as the direction of unwinding of the drum.

Il est nécessaire également de signaler l'inclinaison en Vé largement ouverte des ouvertures de passage des lames hors du tambour évitant l'arrêt intempestif du rouleau de matériau à ce niveau, le rouleau de matériau étant toujours en appui ponctuel ou sur une génératrice sur le tambour d'entrainement. Comparativement à l'art antérieur on ne sent plus le passage formant méplat de la fente rectiligne du tambour et sur laquelle pouvait prendre appui le rouleau de papier.It is also necessary to indicate the wide open V-shaped inclination of the openings for the passage of the blades out of the drum avoiding the untimely stopping of the roll of material at this level, the roll of material being always in point contact or on a generator on the training drum. Compared to the prior art, one no longer feels the passage forming a flat portion of the rectilinear slot of the drum and on which the roll of paper could bear.

Ainsi, selon l'invention la coupe d'une bande de papier s'effectue selon une demarche et un procédé original. La coupe s'effectue en deux temps, en deux zones de coupe différentes in situ dans l'appareil et gràce à un positionnement particulier des lames de coupe, et de leurs dentures respectives, la ligne de coupe sur la bande de papier est rectiligne et perpendiculaire à ses bords.Thus, according to the invention the cutting of a strip of paper is carried out according to an approach and an original process. Cutting takes place in two stages, in two different cutting zones in situ in the device and thanks to a particular positioning of the cutting blades, and their respective teeth, the cutting line on the paper strip is rectilinear and perpendicular to its edges.

Gràce à ces différents agencements, on peut diminuer la force des différents ressorts de rappel et donc leur coût. On peut sans risque de déchirement inopiné tirer du matériau d'essuyage très fin même avec les mains mouillées.Thanks to these different arrangements, it is possible to reduce the strength of the various return springs and therefore their cost. It is without risk of unexpected tearing to pull very fine wiping material even with wet hands.
