Abstract

The end piece for a roll of wiping material comprises a cylindrical bearing surface tightly fitted into a core that supports the roll, a transverse flange that protrudes from the cylindrical bearing surface and rests against an opposite-facing surface of the core and the roll, and an axially extending neck that has a head with an internal hole and a hollowed-out section forming a guide groove. The hollowed-out section is located between the head and the cylindrical bearing surface. The head and part of the hollowed-out section are deformable and internally provided with a hole that creates deliberate fragility facilitating, by crushing, their deformation as the core and the end piece are extracted from an accommodating side plate. After the core and end piece have been extracted, the head of the end piece is, in its final state, permanently deformed and cannot be reused.

Description

EMBOUT JETABLE POUR BOBINE DE MATERIAU D'ESSUYAGE DISPOSABLE TIP FOR COIL OF WIPING MATERIAL
ET APPAREIL DISTRIBUTEUR DE MATERIAU D'ESSUYAGEAND APPARATUS FOR DISPENSING WIPING MATERIAL
RECEVANT UN TEL EMBOUTRECEIVING SUCH A TIP
L'invention se rattache au secteur technique des appareils de distribution des papiers ouatés, à coupe automatique ou non automatique. Ces appareils distributeurs peuvent avoir différentes applications telles que essuie-mains, papier toilettes ou similaires.The invention relates to the technical sector of paper dispensing devices hooded, automatic or non-automatic cutting. These dispensing devices may have different applications such as hand towels, toilet paper or the like.
Le demandeur a développé de nombreux appareils distributeurs de matériau d'essuyage qui comprennent un carter (1) avec couvercle (2) de protection à l'intérieur duquel est disposé, à partir de flasques supports latéraux (3), un tambour (5) recevant un dispositif de coupe intérieur (non représenté) actionné lors de la traction de la bande de matériau tirée par l'utilisateur, issue d'une bobine de matériau (6). Celle-ci peut être disposée en suspension à partir des flasques latéraux, ou être directement en appui sur le tambour. La bobine de matériau d'essuyage qui est montée sur les flasques supports (4) est enroulée serrée sur un mandrin support (7). Ce dernier reçoit, à au moins une de ses extrémités, un embout (8) qui sera susceptible de se positionner sur le flasque (4) du carter en regard, l'autre extrémité du mandrin venant se positionner sur le flasque en regard agencé avec une portée réceptrice (9) conformée lors du moulage ou disposée sur une languette flexible (10) articulée par rapport à son flasque support (4). Ces embouts sont généralement réalisés sous forme cylindrique avec une collerette transversale en débordement venant en appui contre la face en regard du mandrin et de la bobine, une partie cylindrique intérieure étant engagée à force dans le mandrin, l'embout présentant, en outre, et à l'avant, un appendice en prolongement axial se fixant dans une échancrure du flasque support considéré.The applicant has developed numerous wipe material dispensing devices which comprise a housing (1) with a protective cover (2) inside which a drum (5) is arranged from side support flanges (3). receiving an inner cutting device (not shown) actuated during the pulling of the web of material drawn by the user, from a reel of material (6). This can be arranged in suspension from the side flanges, or be directly on the drum. The spool of wiping material which is mounted on the support flanges (4) is tightly wound on a support mandrel (7). The latter receives, at at least one of its ends, a tip (8) which will be able to be positioned on the flange (4) of the casing opposite, the other end of the mandrel coming to be positioned on the flange facing arranged with a receiving surface (9) shaped during molding or arranged on a flexible tongue (10) articulated with respect to its support flange (4). These endpieces are generally made in cylindrical form with a transverse overflow flange bearing against the opposite face of the mandrel and the spool, an inner cylindrical portion being forcibly engaged in the mandrel, the endpiece having, in addition, and in the front, an appendage in axial extension being fixed in a notch of the support flange considered.
Selon les développements exploités par les licenciés du demandeur, l'embout présente un simple appendice rectiligne, ou bien il peut présenter, dans la longueur dudit appendice, une tête en extrémité et une portée cylindrique adjacente à la collerette. Il peut comporter aussi une zone évidée formant rainurage et chemin de guidage comme illustré figure 2. Dans ce cas, en effet, ledit embout est amené à coopérer avec un guide (11) articulé rapporté sur le flasque support (4) porte bobine et facilitant l'introduction de la bobine de matériau d'essuyage et son maintien par déplacement du guide à l'encontre d'un moyen élastique de rappel non représenté. Le guide support présente des saillies (l ia) formées intérieurement sur les parois de son ouverture de passage et d'introduction de l'embout. Une telle disposition a été décrite dans le brevet PCT du demandeur WO 2005/094652.According to the developments exploited by the licensees of the applicant, the tip has a simple rectilinear appendage, or it may have, in the length of said appendix, a head end and a cylindrical bearing adjacent to the collar. It may also comprise a recessed area forming a groove and guiding path as illustrated in FIG. 2. In this case, in fact, said end piece is made to cooperate with a hinged guide (11) attached to the support flange (4) carrying a spool and facilitating the introduction of the coil of wiping material and its retention by displacement of the guide against an elastic means of return not shown. The support guide has projections (l ia) formed internally on the walls of its opening passage and introduction of the tip. Such an arrangement has been described in applicant PCT patent WO 2005/094652.
Dans ce document, il a été décrit aussi la possibilité d'aménager le guide avec des évidements opposés de part et d'autre du chemin de guidage formant rainurage. Dans cette mise en œuvre, le mandrin reçoit un seul embout disposé à une extrémité et coopérant avec le flasque support précité, tandis que l'autre extrémité du mandrin vient se centrer sur une portée conformée sur le flasque en regard. La disposition des évidements opposés, telle que rappelée précédemment, autorise le basculement du mandrin vers le bas lorsque la bobine de matériau est épuisée. Dans ce cas, le mandrin et l'embout monté à son extrémité sont récupérables et peuvent être ou non réutilisés ou jetés, mais sans qu'il n'y ait de modification de l'apparence et des caractéristiques du mandrin et des embouts. Le problème posé est celui de la réutilisation des embouts par des personnes ou compétiteurs concurrents qui peuvent être amenés à les reconditionner sur des mandrins avec des bobines d'essuyage ne venant pas des prescripteurs d'origine des appareils de distribution de matériaux d'essuyage concernés.In this document, it has also been described the possibility of arranging the guide with opposite recesses on either side of the grooving guide path. In this implementation, the mandrel receives a single endpiece disposed at one end and cooperating with the aforementioned support flange, while the other end of the mandrel is centered on a bearing formed on the flange opposite. The arrangement of the opposite recesses, as recalled above, allows the tilting of the mandrel down when the reel of material is exhausted. In this case, the mandrel and the end-mounted tip are recoverable and may or may not be reused or discarded, but without any change in the appearance and characteristics of the mandrel and bits. The problem posed is that of the reuse of the tips by competing persons or competitors who can be made to recondition them on mandrels with wiping coils not coming from the original prescribers of the wiping material distribution apparatus concerned. .
Pour tenter de répondre à cette situation, le demandeur a développé des améliorations sur les parties réceptrices de l'embout dans l'appareil, c'est-à-dire sur les flasques du carter ou sur un guide pivotant support décrit dans le brevet PCT 2005/094652 du demandeur. Une autre solution technique a été décrite dans le brevet Français n° 2879090 pour un embout serrure décrit et imaginé par le demandeur. Il s'agit en fait d'un dispositif de verrouillage de l'embout qui empêche son enlèvement par simple retrait.To try to respond to this situation, the applicant has developed improvements on the receiving parts of the nozzle in the device, that is to say on the flanges of the housing or on a pivoting support guide described in the PCT patent. 2005/094652 of the applicant. Another technical solution has been described in French Patent No. 2879090 for a lock tip described and imagined by the applicant. It is actually a locking device of the tip that prevents removal by simple withdrawal.
En pratique, cette solution reste coûteuse à mettre en œuvre avec un nombre de pièces supplémentaires pour l'obtention de la fonction précitée. En outre, cela ne résout pas la possibilité de réutiliser l'embout qui reste intact dans sa forme et sa structure.In practice, this solution remains expensive to implement with a number of additional parts to obtain the aforementioned function. In addition, this does not solve the possibility of reusing the tip which remains intact in its shape and structure.
On connaît par ailleurs des embouts pour bobines de matériaux d'essuyage décrits dans les brevets US 4.671.466 et DE 19723076. Ceux-ci ne sont pas du tout adaptés pour répondre au problème posé par le demandeur et sont établis avec une configuration de leur partie tête rigide nonobstant la présence d'un trou intérieur car leur fonction n'est pas en rapport avec le problème posé.Also known are tips for spools of wiping materials described in US 4,671,466 and DE 19723076. These are not at all adapted to address the problem posed by the applicant and are established with a configuration of their own. rigid head part notwithstanding the presence of an inner hole because their function is not related to the problem.
La démarche du demandeur a donc été de réfléchir à nouveau sur ce problème en vue de permettre à l'exploitant du distributeur de matériau d'essuyage d'avoir des embouts propres, non réutilisables par des concurrents indélicats.The applicant's approach was therefore to reflect again on this problem in order to allow the operator of the material distributor wipers to have clean tips, not reusable by unscrupulous competitors.
La solution imaginée par le demandeur résulte d'une attitude pour le moins inattendue et qui va à l'opposé de considérations liées au gaspillage, cette solution consistant dans l' autodestruction des embouts en fin de bobine.The solution devised by the applicant results from an attitude to say the least unexpected and which goes to the opposite of considerations related to wastage, this solution consisting in the self-destruction of the ends at the end of the coil.
En d'autres termes, la solution apportée par le demandeur vise à rendre inutilisable l'embout considéré après finition de la bobine, par la concurrence et pour lui-même également. En cela, la solution du demandeur est pour le moins inattendue et se situe à l'opposé des objectifs classiques dans l'industrialisation de produits, et des exigences environnementales en matière de gaspillage.In other words, the solution provided by the applicant aims to make unusable the endpiece considered after finishing the coil, by the competition and for himself as well. In this, the applicant's solution is, to say the least, unexpected and is the opposite of conventional objectives in the industrialization of products, and environmental demands for waste.
La solution imaginée par le demandeur s'applique à tout type d'appareil distributeur de matériau d'essuyage qui utilise au moins un embout introduit dans le mandrin support de la bobine de matériau d'essuyage.The solution devised by the applicant applies to any type of wipe material dispensing apparatus which uses at least one nozzle inserted into the support mandrel of the wiping material coil.
Selon une première caractéristique de l'invention, l'embout pour bobine de matériau d'essuyage du type comprenant une portée cylindrique, emmanchée serrée dans le mandrin support de la bobine, avec une collerette transversale d'appui en débordement de la portée cylindrique et venant en appui sur la face en regard du mandrin et de la bobine, et un appendice en prolongement axial présentant une tête avec un trou intérieur et une section évidée formant rainure de guidage, ladite section évidée étant disposée entre la tête d'extrémité et une portée cylindrique adjacente à la collerette, ledit embout étant remarquable en ce que, la tête de l'appendice axial et une partie de la section évidée formant rainurage constituant le chemin de guidage, sont déformables et agencées intérieurement avec un trou de fragilité permettant par écrasement leur déformation lors de l'extraction du mandrin et de l'embout du flasque récepteur, et en ce que après extraction du mandrin et de son embout, la tête dudit embout est à l'état final déformée de manière définitive et non réutilisable.According to a first characteristic of the invention, the tip for a spool of wiping material of the type comprising a cylindrical bearing, tightly fitted in the mandrel support of the spool, with a transverse bearing flange overflowing the cylindrical bearing surface and bearing on the facing face of the mandrel and the coil, and an axially extending appendix having a head with an inner hole and a recessed section forming a guide groove, said recessed section being disposed between the end head and a cylindrical bearing adjacent to the collar, said tip being remarkable in that, the head of the axial appendix and a portion of the grooved recess section constituting the guide path, are deformable and arranged internally with a brittle hole for crushing their deformation during the extraction of the mandrel and the tip of the receiver flange, and in that after extraction of the mandrel and its tip, the head of said tip is in the final state permanently deformed and non-reusable.
Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These and other characteristics will be apparent from the rest of the description.

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.
En se référant aux figures 6, 8 et 9, l'embout (12) présente une portée cylindrique (12a) avec des saillies (12b) et une collerette transversale (12c) pour venir s'engager à emmanchement serrée dans le mandrin. Cette zone de l'embout qui est destinée à se trouver dans le mandrin peut être aménagée différemment, celle illustrée aux figures des dessins l'étant simplement à titre d'exemple.Referring to Figures 6, 8 and 9, the tip (12) has a cylindrical surface (12a) with projections (12b) and a transverse flange (12c) to engage tight fit into the mandrel. This area of the tip which is intended to be in the mandrel can be arranged differently, that illustrated in the figures of the drawings being simply by way of example.
La partie avant de l'embout, c'est-à-dire se situant hors du mandrin, présente à partir de la collerette transversale, un appendice axial comprenant une portée conique (12d) prolongée par une portée cylindrique (12e), une tête (12f) en extrémité et, entre les deux, une section évidée formant rainurage (12g) pour constituer chemin de guidage. La présence ou non de la partie conique (12d) dépend de la configuration de l'embout.The front part of the end piece, that is to say located outside the mandrel, presents from the transverse flange, an axial appendage comprising a conical seat (12d) extended by a cylindrical seat (12e), a head (12f) at the end and, in between, a grooved recess section (12g) for forming a guide path. The presence or absence of the conical portion (12d) depends on the configuration of the tip.
Selon l'invention, la tête (12f) et la section évidée (12g) formant rainurage de l'embout (10) sont déformables et sont agencées intérieurement avec un trou (12h) de fragilité dont la fonction sera d'autoriser par suite d'écrasement la déformation d'au moins ladite tête et le cas échéant la section évidée lors de l'effort d'extraction du mandrin après fermeture de la bobine. Cette déformation est permise par la flexibilité de la matière constitutive de l'embout, et ainsi du diamètre et de la profondeur du trou traversant borgne ainsi exécuté.According to the invention, the head (12f) and the recessed section (12g) grooving the tip (10) are deformable and are arranged internally with a hole (12h) of fragility whose function will be to allow as a result crushing the deformation of at least said head and if necessary the recessed section during the extraction force of the mandrel after closing the coil. This deformation is enabled by the flexibility of the constituent material of the tip, and thus the diameter and the depth of the blind through hole thus executed.
Le guide (11) illustré figure 2 ou figures 6, 7, 9 est ainsi agencé avec une fente d'introduction de l'embout avec une zone en saillie correspondant à la section évidée (12g) de l'embout pour assurer son guidage. Il définit en quelque sorte une forme en étranglement et la partie arrière de la tête (12f) de l'embout vient en appui contre la paroi intérieure de ladite zone en saillie. En situation normale figures 5 et 6, en présence de matériau sur le mandrin de la bobine, l'embout a parfaitement retenu la partie évidée étant centrée autour de la zone en saillie du guide. Une languette (1 Ib) à capacité élastique de déformation solidaire du guide maintient l'embout en position et empêche son retrait.The guide (11) illustrated in FIG. 2 or FIGS. 6, 7, 9 is thus arranged with a slot for introducing the endpiece with a protruding zone corresponding to the recessed section (12g) of the end piece to ensure its guidance. It defines in a way a form in constriction and the rear part of the head (12f) of the tip abuts against the inner wall of said projecting zone. In the normal situation in FIGS. 5 and 6, in the presence of material on the mandrel of the spool, the endpiece has perfectly retained the recessed portion being centered around the projecting zone of the guide. A tongue (1 Ib) resilient deformation integral with the guide maintains the tip in position and prevents its withdrawal.
Lorsque la bobine est complètement dévidée, c'est-à-dire que le mandrin est nu (figure 8), il convient d'extraire et d'enlever le mandrin. Celui-ci est basculé selon la flèche (Fl) et la partie haute de la tête déformable de l'embout vient en contre-appui de la partie fixe en saillie du guide. La traction selon la flèche (F2) en combinaison avec l'effort de basculement va provoquer l'écrasement d'au moins la tête de l'embout et le cas échéant aussi de la partie évidée. Le trou (12h) va permettre le rapprochement des parois de la tête de l'embout, et ainsi le passage par resserrement de la tête dans l'étranglement ou ouverture formée sur le fond entre ses parties en saillie (figure 9). De par la nature du matériau constitutif de l'embout et de sa partie avant, la tête (12h) à l'état final est alors déformée de manière irréversible avec par exemple une configuration ovalisée comme représentée figure 10, régulière ou irrégulière selon la force et les efforts de traction.When the reel is completely unwound, that is to say that the mandrel is bare (Figure 8), it is necessary to extract and remove the mandrel. It is tilted according to the arrow (Fl) and the upper part of the head deformable nozzle comes against the support of the fixed portion protruding from the guide. The traction according to the arrow (F2) in combination with the tilting force will cause the crushing of at least the head of the nozzle and if necessary also of the recessed portion. The hole (12h) will allow the approximation of the walls of the head of the nozzle, and thus the passage by tightening of the head in the constriction or opening formed on the bottom between its protruding parts (Figure 9). Due to the nature of the material constituting the tip and its front portion, the head (12h) in the final state is then irreversibly deformed with for example an ovalized configuration as shown in FIG. 10, regular or irregular depending on the force and traction efforts.
L'embout du mandrin ne peut plus être utilisé de par sa déformation de la partie avant répondant au problème posé. La déformation obtenue de la tête de l'embout et ainsi de sa section évidée n'engendre pas de risque de cassure ou de rupture de la tête par rapport au corps de l'embout, de sorte qu'il n'y a pas de détritus pouvant rester dans l'appareil distributeur.The tip of the mandrel can no longer be used by its deformation of the front part answering the problem. The deformation obtained from the head of the nozzle and thus its recessed section does not generate any risk of breakage or rupture of the head relative to the body of the nozzle, so that there is no detritus that may remain in the dispensing apparatus.
Sans sortir du cadre de l'invention, la tête de l'embout sur sa face avant présente partiellement dans son épaisseur une forme en croisillons (12m) pour faciliter le pliage et la déformation de la tête de l'embout et constituant une amorce de fragilité.Without departing from the scope of the invention, the head of the tip on its front face has partially in its thickness a cross-shaped (12m) to facilitate the folding and deformation of the head of the tip and constituting a primer. fragility.
Il y a lieu de décrire la variante de l'embout, illustrée figure 12, qui est agencée avec une tête déformable pour remplir la fonction de déformation, entraînant sa détérioration, rappelée précédemment, mais aussi une autre fonction de verrouillage dans un volet articulé associé à un flasque support de la bobine de matériau dans l'appareil distributeur. Selon la figure 12, les références de l'embout déformable sont les mêmes, à l'exception du fait que la section évidée (12g) est de configuration très particulière. Elle présente en effet deux rétrécissements opposés (12gl) de forme courbée qui réduisent l'épaisseur de la section (dl) de l'ordre de 1,5 à 2 mm, tandis que la section (d2) dans l'autre plan perpendiculaire est de l'ordre de 3 à 4 mm. Outre de favoriser la déformation de la tête de l'embout, cette disposition offre un avantage spécifique dans le verrouillage de l'embout.It is necessary to describe the variant of the nozzle, illustrated in Figure 12, which is arranged with a deformable head to perform the deformation function, causing its deterioration, recalled above, but also another locking function in an associated hinged flap to a support flange of the material spool in the dispensing apparatus. According to FIG. 12, the references of the deformable tip are the same, with the exception that the recessed section (12g) is of very particular configuration. It has indeed two opposite contractions (12gl) of curved shape which reduce the thickness of the section (dl) of the order of 1.5 to 2 mm, while the section (d2) in the other perpendicular plane is of the order of 3 to 4 mm. In addition to promoting the deformation of the head of the tip, this arrangement offers a specific advantage in locking the tip.
Contrairement à l'utilisation de la languette de verrouillage (Hb) représentée figures 2, 3, 4, 5 des dessins, l'embout à tête déformable est utilisable avec un dispositif représenté aux figures 14, 15 et 16. L'un des flasques (13) récepteur du mandrin porte bobine est agencé dans sa partie intérieure avec une forme en siège (13a) délimitée par un contour périphérique correspondant à la forme d'une pièce support (14) en forme de volet, et présentant des berceaux (13b) récepteurs des axes d'articulation (14a) dudit volet. A l'intérieur du volume du siège, débouche partiellement une fente (13c) sensiblement horizontale de l'avant vers l'arrière définissant le passage de l'embout. La pièce support formant volet (14) présente un chemin de guidage (14b) défini par une lumière oblongue (14c) établie dans son épaisseur avec des nervurages longitudinaux (14d) formant rails de guidage. La face arrière (14e) présente un évidement (14f) formant siège d'un ressort (15) qui prend appui sur la face en regard du flasque.In contrast to the use of the locking tongue (Hb) shown in FIGS. 2, 3, 4, 5 of the drawings, the tip with deformable head can be used with a device represented in FIGS. 14, 15 and 16. One of the flanges (13) receiver of the spool mandrel is arranged in its inner part with a seat shape (13a) delimited by a peripheral contour corresponding to the shape of a support piece (14) in the form of flap, and having cradles (13b). ) receivers articulation axes (14a) of said flap. Inside the seat volume, partially opens a slot (13c) substantially horizontal from front to rear defining the passage of the nozzle. The flap support member (14) has a guide path (14b) defined by an oblong slot (14c) established in its thickness with longitudinal ribs (14d) forming guide rails. The rear face (14e) has a recess (14f) forming a seat of a spring (15) which bears on the opposite side of the flange.
La configuration particulière de l'embout, selon les figures 12 et 13, permettent de coopérer avec le dispositif précité avec, en particulier, un rétrécissement maximum de la distance entre les nervurages de guidage entre 1,5 et 2 cm, et permettant un seul sens possible d'introduction de l'embout selon sa section (dl) au vu de sa section différente (d2) dans un plan par rapport à l'autre. Au demeurant, des repères (12i), sous forme de saillies ou autres, peuvent être établis sur l'embout matérialisant le sens d'introduction de celui-ci dans la pièce support formant volet. En outre, et selon une spécificité apportée à la pièce support précitée, l'extrémité de la lumière oblongue (14e) est aménagée avec un chambrage (14g) qui correspond au profil de la tête de l'embout.The particular configuration of the nozzle, according to FIGS. 12 and 13, makes it possible to cooperate with the aforementioned device with, in particular, a maximum narrowing of the distance between the guide ribs. between 1.5 and 2 cm, and allowing only one possible direction of introduction of the tip according to its section (dl) in view of its different section (d2) in one plane relative to the other. Moreover, pins (12i), in the form of projections or other, can be established on the tip materializing the direction of introduction thereof into the flap support piece. In addition, and according to a specificity provided to the aforementioned support piece, the end of the oblong slot (14e) is arranged with a recess (14g) which corresponds to the profile of the head of the tip.
Ainsi qu'il apparaît aux figures 15 et 16, lors de la mise en place de l'embout sur la pièce support formant volet articulé, le ressort (15) est comprimé, la pièce support prenant contact avec le flasque support récepteur. En fin ce course, la tête de l'embout vient se loger dans le chambrage (14g) et, sous l'effet de détente du ressort, il y a verrouillage de l'embout.As shown in Figures 15 and 16, during the introduction of the tip on the support part forming hinged flap, the spring (15) is compressed, the support part contacting the receiver support flange. In the end this race, the head of the tip is housed in the recess (14g) and, under the effect of relaxation of the spring, there is locking of the tip.
L'enlèvement de ce dernier avec le mandrin de la bobine s'effectue dans les conditions décrites précédemment avec sa détérioration par déformation de la tête.The removal of the latter with the mandrel of the coil is carried out under the conditions described above with its deterioration by deformation of the head.
Cette variante de mise en œuvre de l'embout présente un avantage spécifique donné par la section différenciée de la zone évidée (12g), ce qui a pour but d'empêcher, par l'aménagement spécifique de la pièce support en forme de volet, toute utilisation d'embouts de la concurrence qui, ainsi, ne peuvent pénétrer dans la pièce support précitée de par leur configuration et section non appropriée. La solution apportée par le Demande apparaît simple à mettre en œuvre, mais le choix de cette solution apparaissait pour le moins non évident par rapport au problème posé à l'origine. Si l'on considère que de très nombreux fabricants d'appareils distributeurs de matériaux d'essuyage existent à travers le monde avec des quantités considérables de plusieurs centaines de millions de bobines d'essuyage annuellement. This variant of implementation of the tip has a specific advantage given by the differentiated section of the recessed area (12g), which is intended to prevent, by the specific arrangement of the support piece shaped flap, any use of competitive tips which, thus, can not enter the aforementioned support part by their configuration and inappropriate section. The solution provided by the Application appears simple to implement, but the choice of this solution appeared at least not obvious compared to the problem originally posed. Considering that a large number of manufacturers of wiper materials dispensers exist around the world with considerable amounts of several hundred million wiping coils annually.
