The capillary product is applied onto the lock, coating at least part (9) of it, which is rolled around the outer periphery (5) of the support.

Description

La présente invention a pour objet un procédé d'application partielle d'un produit capillaire sur des mèches. L'intérêt de cette invention est qu'elle permet d'appliquer un tel produit à différents niveaux sur des mèches, et ainsi d'obtenir un effet visuel d'alternance entre des zones enduites, et donc traitées, et des zones non traitées.The subject of the present invention is a method of partially applying a hair product on locks. The advantage of this invention is that it allows to apply such a product at different levels on wicks, and thus to obtain a visual effect of alternation between coated and therefore treated areas and areas not processed.

Dans l'état de la technique, il est connu des dispositifs et des méthodes permettant d'obtenir l'enduction d'un produit capillaire, notamment de décoloration et ou de coloration, sur une mèche de cheveux, notamment sur toute sa longueur. Généralement pour réaliser de telles mèches, et selon l'une des techniques les plus simples, la mèche est placée sur une palette. Le produit est appliqué sur toute la longueur de la mèche au moyen d'un pinceau. Les mèches sont laissées à l'air libre et séparées du reste de la chevelure par des bandes de coton placées à la racine des cheveux. Après un temps de pose adéquat, les cheveux sont lavés de manière conventionnelle. La méthode est longue et fastidieuse. De plus, les mèches traitées sont inévitablement mises en contact avec le reste de la chevelure, ce qui compromet dans une large mesure l'esthétique du résultat.In the state of the art, devices and methods are known allowing the coating of a hair product, in particular bleaching and or coloring, on a lock of hair, in particular over its entire length. Generally to make such wicks, and according to one of the techniques, simpler, the wick is placed on a pallet. The product is applied to the entire length of the wick using a brush. The locks are left at the air and separated from the rest of the hair by cotton bands placed at the hairline. After an adequate exposure time, the hair is washed conventionally. The method is long and tedious. Moreover, the treated wicks are inevitably brought into contact with the rest of the hair, which largely compromises the aesthetics of the result.

On connaít également du document US-5,992,425, un rouleau en mousse qui peut être imprégné d'un produit capillaire et sur lequel on enroule la mèche dans le but d'enduire cette mèche de produit sur toute sa longueur d'enroulement.We also know from document US-5,992,425, a foam roller which can be impregnated with a hair product and on which the wick is wound in order to coat this wick with product over its entire winding length.

Il existe un besoin de réaliser des motifs dans la chevelure qui soient différents de la simple alternance de mèches traitées et de mèches non traitées et qui apportent un nouvel effet visuel.There is a need to make patterns in the hair which are different from the simple alternation of treated wicks and untreated wicks and which bring a new visual effect.

Pour obtenir des motifs au milieu de la chevelure, on connaít du document US-5,664,590, l'utilisation de pochoirs permettant de délimiter des zones de la chevelure à enduire pour obtenir le motif désiré. Cependant de tels pochoirs ne sont pas faciles à positionner correctement relativement aux cheveux. Par ailleurs, il est difficile au moyen de ces pochoirs de reproduire un même motif avec une certaine régularité de forme et d'espacement sur l'ensemble de la chevelure. On connaít également du document DE-41,22,539, un bigoudi autour duquel on effectue un enroulement hélicoïdal de la mèche, ce bigoudi étant ensuite inséré dans une coque ajourée longitudinalement. Une ouverture longitudinale de la coque donne ainsi accès à des portions visibles de boucles de la mèche. Si la mèche est régulièrement enroulée, alors les portions visibles seront régulièrement espacées le long de la mèche. A la manière d'un pochoir, du produit peut ensuite être appliqué sur ces portions visibles de boucle.To get patterns in the middle of the hair, we know the document US Pat. No. 5,664,590, the use of stencils making it possible to delimit areas of the hair to be coated to obtain the desired pattern. However, such stencils do not are not easy to position correctly relative to the hair. Otherwise, it is difficult with these stencils to reproduce the same pattern with a a certain regularity of shape and spacing on the whole of the hair. We also knows from document DE-41,22,539, a curler around which one performs a helical winding of the wick, this curler then being inserted in a longitudinally perforated shell. A longitudinal opening of the shell thus gives access to visible portions of loops of the wick. If the wick is regularly wound, then the visible portions will be regularly spaced along the wick. Like a stencil, product can then be applied to these visible portions of the loop.

Un objet de l'invention est de proposer une solution permettant d'obtenir à moindre coût la possibilité de réaliser un même motif à différents niveaux d'une même mèche, sans enduire la mèche en entier, en considérant ladite mèche des racines aux pointes. On peut ainsi obtenir des effets nouveaux et originaux sur des mèches de cheveux.An object of the invention is to propose a solution making it possible to obtain lower cost the possibility of producing the same pattern at different levels of a same wick, without coating the entire wick, considering said wick of roots to ends. We can thus obtain new and original effects on locks of hair.

L'invention a pour objet un procédé d'application d'un produit capillaire sur une mèche de cheveux comportant les étapes suivantes:

  • on enroule une portion de la mèche autour d'un support de manière à former au moins une boucle autour du support,
  • on retient une première extrémité de la mèche dans une première encoche élastiquement déformable du support,
  • et on applique le produit capillaire sur la mèche de manière à enduire au moins une partie de cette portion de mèche enroulée sur le pourtour extérieur du support.
The subject of the invention is a method of applying a hair product to a lock of hair comprising the following steps:
  • a portion of the wick is wound around a support so as to form at least one loop around the support,
  • a first end of the wick is retained in a first elastically deformable notch of the support,
  • and the hair product is applied to the lock so as to coat at least part of this portion of lock wound on the outer periphery of the support.

De préférence, cette encoche élastiquement déformable comporte de préférence deux bords sensiblement jointifs aptes à s'écarter élastiquement l'un de l'autre pour permettre l'introduction de la première extrémité de la mèche, cette extrémité étant alors retenue par la force de rappel élastique de ces deux bords tendant à retrouver leur disposition sensiblement jointive.Preferably, this elastically deformable notch includes preferably two substantially contiguous edges capable of moving apart one on the other to allow the introduction of the first end of the wick, this end then being retained by the elastic restoring force of these two edges tending to regain their substantially contiguous arrangement.

De préférence, pour appliquer le produit on utilise un moyen d'application apte à se charger en au moins une quantité de ce produit, ce moyen d'application étant ensuite appliqué sur le pourtour extérieur du support, notamment sur au moins une des zones de ce pourtour extérieur recouverte d'une portion de ladite mèche. Preferably, to apply the product, an application means is used. able to load at least a quantity of this product, this means of application then being applied to the outer periphery of the support, in particular on the minus one of the zones of this outer periphery covered with a portion of said wick.

De préférence, on entoure le support avec la portion de mèche de manière à présenter plusieurs boucles s'enroulant en spirale, non superposées, autour du support.Preferably, the support is surrounded with the wick portion so to present several loops wound in a spiral, not superimposed, around the support.

Avantageusement, on enduit le pourtour extérieur du support selon une bande parallèle à un axe d'allongement principal du support. Ainsi chaque boucle de la portion de mèche qui se trouve à l'intersection de cette bande est enduite de produit selon une largeur identique d'une boucle à l'autre. De plus, dans la mesure où la portion de mèche est enroulée de manière homogène sur le support, et dans le cas où le support est de section constante, la portion de mèche une fois déroulée comporte alors plusieurs zones enduites de même hauteur, en considérant la hauteur relativement à l'axe de la mèche, ces zones étant réparties à intervalles réguliers le long de la mèche. Ces zones sont espacées les unes des autres sur une même mèche d'un même espacement, la distance représentée par cet espacement étant supérieure au périmètre extérieur du support auquel on a retranché la largeur de la bande.Advantageously, the outer periphery of the support is coated according to a strip parallel to a main axis of elongation of the support. So each loop of the portion of wick which is at the intersection of this strip is coated with produced with an identical width from one loop to another. In addition, to the extent where the wick portion is homogeneously wound on the support, and in if the support is of constant section, the wick portion once unrolled then comprises several coated zones of the same height, in considering the height relative to the axis of the drill bit, these areas being distributed at regular intervals along the wick. These areas are spaced from each other. others on the same drill bit with the same spacing, the distance represented by this spacing being greater than the external perimeter of the support to which we have subtract the width of the strip.

Alternativement, le produit peut être appliqué sur le pourtour extérieur du support en suivant une spirale, ou tout autre chemin, notamment dans le cas où la portion de mèche est enroulée de manière homogène sur ce support, on obtient alors un premier espacement entre deux zones consécutives enduites et un deuxième espacement entre deux autres zones consécutives enduites, tels que ce deuxième espacement est différent du premier espacement. Généralement les zones enduites de ladite mèche forment des bandeaux, et l'espacement entre des bandeaux consécutifs est alors variable. En variante, pour obtenir cet espacement variable, on peut enrouler la portion de mèche avec un pas donné mais sur un support de section variable, par exemple tronconique.Alternatively, the product can be applied to the outer periphery of the support by following a spiral, or any other path, in particular in the case where the portion of wick is homogeneously wound on this support, we obtain then a first spacing between two consecutive coated zones and a second spacing between two other consecutive coated areas, such as this second spacing is different from the first spacing. Generally the coated areas of said wick form bands, and the spacing between consecutive bands is then variable. Alternatively, to get this spacing variable, you can wind the wick portion with a given pitch but on a support of variable section, for example frustoconical.

Avantageusement le support est cylindrique et comporte une section de diamètre choisi en fonction de l'espacement désiré entre deux zones distinctes d'enduction de la portion de mèche, c'est à dire en fonction d'un espacement espéré des bandeaux, ou zones, de mèches traitées connaissant la largeur des bandes généralement appliquées sur le pourtour extérieur du support. De plus, le diamètre de ce support est également choisi en fonction de la longueur de la portion de mèche à enrouler autour du support. La forme cylindrique permet de ne pas casser les cheveux en les enroulant sur un dispositif ne comportant de facto pas d'arêtes sur son pourtour extérieur.Advantageously, the support is cylindrical and has a section of diameter chosen according to the desired spacing between two distinct zones coating the wick portion, i.e. depending on a spacing hoped for bands, or zones, of treated locks knowing the width of the bands generally applied on the outer periphery of the support. In addition, the diameter of this support is also chosen according to the length of the portion of wick to wrap around the support. The cylindrical shape allows not break the hair by winding it on a device that does not have de facto no edges on its outer periphery.

Selon un premier mode de réalisation, la mèche est retenue dans une encoche définie dans un plan parallèle à l'axe d'allongement principal, et débouche au niveau d'une extrémité du support relativement à son axe d'allongement principal.According to a first embodiment, the wick is retained in a notch defined in a plane parallel to the main elongation axis, and opens at one end of the support relative to its axis main elongation.

Selon un deuxième mode de réalisation, la mèche est retenue dans une encoche, définie dans un plan formant un angle non nul avec cet axe d'allongement principal, cet angle étant par exemple de 90°.According to a second embodiment, the wick is retained in a notch, defined in a plane forming a non-zero angle with this axis main elongation, this angle being for example 90 °.

Avantageusement cette encoche est chanfreinée de manière à favoriser l'introduction de la mèche.Advantageously, this notch is chamfered so as to favor the introduction of the wick.

Dans le procédé selon l'invention, on découpe de préférence le support autour duquel on enroule ensuite la mèche dans un bloc permettant de réaliser plusieurs supports tels que ceux utilisés dans l'invention. On réalise une encoche avec un moyen coupant, par exemple une lame ou un cutter, avant d'enrouler la mèche.In the process according to the invention, the support is preferably cut out around which the wick is then wound in a block allowing to realize several supports such as those used in the invention. We make a notch with a cutting medium, for example a blade or a cutter, before winding the wick.

Préférentiellement on réalise une deuxième encoche dans le support pour y retenir une deuxième extrémité de la mèche. Ainsi la mèche enroulée autour du support peut être tendue et retenue par le biais de ces deux encoches. On peut ainsi au cours d'une première étape disposer toutes les mèches en enroulement chacune autour de leur support respectif, et uniquement au cours d'une seconde étape appliquer sélectivement le produit capillaire sur chacune des mèches ainsi enroulées.Preferably, a second notch is made in the support for there retain a second end of the wick. So the wick wrapped around the support can be tensioned and retained by means of these two notches. We can so during a first step arrange all the wicks in winding each around their respective support, and only during one second step selectively apply the hair product to each strand as well wound.

Pour permettre un enroulement de la portion de mèche sur tout le pourtour extérieur du support, et notamment éviter de superposer deux mèches, la première encoche et la deuxième encoche sont de préférence opposées relativement à l'axe d'allongement principal du support. To allow winding of the wick portion around the entire circumference outside of the support, and in particular avoid overlapping two wicks, the first notch and second notch are preferably opposite relative to the main elongation axis of the support.

Pour faciliter la réalisation des encoches et en particulier de préférence n'utiliser qu'un seul moyen de coupe, les encoches sont avantageusement définies dans des plans parallèles entre eux. En variante, les plans dans lesquels se définissent les encoches sont sécants.To facilitate the realization of the notches and in particular preferably use only one cutting means, the notches are advantageously defined in planes parallel to each other. Alternatively, the planes in which are defined the notches are intersecting.

Préférentiellement, on choisit un support souple élastiquement déformable, et de fabrication aisée et peu coûteuse, on choisit en particulier de découper le support dans une mousse de polymère, de préférence à cellules fermées, par exemple obtenue par extrusion d'une polyoléfine du type polyéthylène, polyester, polyether ou polyuréthane.Preferably, a flexible, elastically deformable support is chosen, and easy and inexpensive to manufacture, we choose in particular to cut the support in polymer foam, preferably with closed cells, by example obtained by extrusion of a polyolefin of the polyethylene, polyester type, polyether or polyurethane.

Par exemple pour déposer le produit capillaire sous la forme d'une bande on utilise un pinceau que l'on déplace sur le pourtour extérieur du support en essayant de ne pas trop écraser les poils du pinceau pour garantir la largeur de la bande réalisée. Ainsi on choisit de préférence un pinceau à poils durs.For example to deposit the hair product in the form of a strip we use a brush that we move around the outer edge of the support trying not to crush the bristles of the brush too much to guarantee the width of the tape made. So we choose preferably a brush with hard bristles.

L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent. Celles ci ne sont présentées qu'à titre indicatif et nullement limitatif de l'invention. Les figures montrent :

La figure 1 montre un support 1 comportant un axe d'allongement principal X, de forme cylindrique, de longueur L considérée le long de l'axe X, et de diamètre D. De préférence, la longueur L est comprise entre 5 et 15 centimètres. De préférence, le diamètre D est compris entre 1 et 5 centimètres.Figure 1 shows a support 1 having a main elongation axis X, of cylindrical shape, of length L considered along the axis X, and of diameter D. Preferably, the length L is between 5 and 15 centimeters. Preferably, the diameter D is between 1 and 5 centimeters.

Le support 1 est découpé de telle sorte que la base 2 et le sommet 3 du cylindre sont orthogonaux à l'axe d'allongement principal X. The support 1 is cut so that the base 2 and the top 3 of the cylinder are orthogonal to the main elongation axis X.

Le support 1 comporte une première encoche 4 formée parallèlement à l'axe X, et donc découpée orthogonalement au sommet 3, cette encoche 4 débouchant au niveau de ce sommet 3, et également de part et d'autre de ce sommet 3 au niveau du pourtour extérieur 5 de ce cylindre. L'encoche 4, également appelé fente 4, comporte deux bords tels que l'un de ces deux bords, au niveau du sommet 3, est chanfreiné 6 de manière à localement indiquer la présence de cette encoche et par ailleurs à faciliter l'introduction d'une portion de mèche dans cette encoche 4, comme cela est proposé sur la figure 2a.The support 1 has a first notch 4 formed parallel to the X axis, and therefore cut orthogonally to the vertex 3, this notch 4 emerging at this summit 3, and also on either side of this vertex 3 at the outer periphery 5 of this cylinder. Notch 4, also called slot 4, has two edges such that one of these two edges, at vertex 3, is chamfered 6 so as to locally indicate the presence of this notch and further facilitate the introduction of a portion of wick in this notch 4, as proposed in Figure 2a.

De préférence, le support est réalisé dans un matériau élastiquement déformable, ainsi toute encoche, par exemple réalisée avec une lame dans ce support, comporte au moins deux bords également élastiquement déformables.Preferably, the support is made of an elastically material deformable, thus any notch, for example made with a blade in this support, has at least two edges which are also elastically deformable.

Figures 1 et 2a-2d, la fente 4 est délimitée par deux demi-cylindres sensiblement jointifs longitudinalement, et aptes à s'écarter élastiquement l'un de l'autre pour permettre l'introduction d'une portion de la mèche au niveau d'une extrémité, ici le sommet 3 du support 1, les deux demi-cylindres de la fente 4 retournant par rappel élastique en position sensiblement jointive lorsque la mèche y est insérée, ce qui permet de l'y retenir sans autre moyen de fixation. La portion de mèche bloquée dans cette fente est donc d'une longueur sensiblement égale au diamètre du support 1.Figures 1 and 2a-2d, the slot 4 is delimited by two half-cylinders substantially contiguous longitudinally, and capable of elastically deviating from one of the other to allow the introduction of a portion of the wick at a end, here the top 3 of the support 1, the two half-cylinders of the slot 4 returning by elastic return to a substantially contiguous position when the wick is inserted into it, which allows it to be retained there without any other means of attachment. The part wick locked in this slot is therefore of substantially equal length to the diameter of the support 1.

Au cours d'une première étape, on isole une mèche M du reste de la chevelure C, cette mèche M est glissée dans la première encoche 4 de manière à ce qu'une portion libre de cette mèche M puisse ensuite coopérer avec le support 1. De préférence, on insère une portion de ladite mèche proche des racines, ou des pointes, dans cette première encoche 4.During a first step, a wick M is isolated from the rest of the hair C, this wick M is slid into the first notch 4 so as to that a free portion of this wick M can then cooperate with the support 1. Preferably, a portion of said wick is inserted close to the roots, or points, in this first notch 4.

Ensuite, comme indiqué sur la figure 2b, on enroule la portion libre de la mèche M sur le pourtour extérieur cylindrique 5 du support 1. La portion libre forme alors des spires en direction de la base 2. de préférence, on enroule toute la portion libre de la mèche sur le support 1. Then, as shown in Figure 2b, the free portion of the wick M on the cylindrical outer periphery 5 of the support 1. The free portion then forms turns towards the base 2. preferably, the whole free portion of the wick on the support 1.

Eventuellement on bloque, Figure 2c, la portion libre au niveau d'une deuxième encoche 7 telle que la première encoche 4, ici réalisée au niveau de la base 2, telle qu'elle est parallèle à l'axe X et donc à la première encoche 4. Elle peut également être chanfreinée 8 et élastiquement déformable.Optionally, Figure 2c blocks the free portion at a second notch 7 such as the first notch 4, here produced at the base 2, as it is parallel to the X axis and therefore to the first notch 4. It can also be chamfered 8 and elastically deformable.

On applique alors le produit sur une zone du pourtour extérieur, en particulier définie comme une bande parallèle à l'axe X et coupant chaque spire sur au moins un arc de spire, figure 2d. On étale le produit de manière à ne pas recouvrir tout le pourtour extérieur du support 1, et pour ainsi n'enduire que partiellement la portion de la mèche qui est enroulée autour.The product is then applied to an area around the outside, in particular defined as a strip parallel to the X axis and cutting each turn on at least one spiral arc, Figure 2d. The product is spread so as not to cover the entire outer periphery of the support 1, and thus only coat partially the portion of the wick that is wrapped around.

Lorsque le temps de pose du produit est révolu, on désengage les portions de cette mèche qui sont éventuellement retenues dans la première encoche 4 et dans la deuxième encoche 7, et on déroule la mèche de manière à la libérer complètement du support 1. Eventuellement on finit le traitement des cheveux, et le résultat obtenu est du type de celui représenté Figure 2e. Dans l'exemple présenté Figure 2e, la bande de produit a coupé en a moins trois sections la mèche M, ce qui aboutit à la présence de trois zones distinctes respectivement 9, 10 et 11 au niveau desquelles la mèche M présente le traitement et ou la coloration lié au produit capillaire localement appliqué, alors que sur le reste de la longueur de la mèche M les fibres kératiniques n'ont pas été mises au contact avec le produit capillaire.When the product exposure time is over, the portions are disengaged of this wick which are possibly retained in the first notch 4 and in the second notch 7, and we unroll the wick so as to release it completely of support 1. Optionally, the hair treatment is finished, and the result obtained is of the type shown in Figure 2e. In the example shown in Figure 2e, the product strip cut into at least three sections the wick M, which results in the presence of three distinct zones respectively 9, 10 and 11 at which the wick M presents the treatment and or the coloration linked to the locally applied hair product, while on the rest of the length of wick M keratin fibers have not been brought into contact with the hair product.

Ces zones 9, 10 et 11 ont sensiblement la même hauteur 12 relativement à la longueur de la mèche. En fonction de la manière dont le produit capillaire est appliqué sur le pourtour extérieur du support 1, ces zones pourraient avoir des longueurs différentes. Par ailleurs, on a un premier espacement 13 entre les deux premières zones 9 et 10, et un deuxième écartement 14 entre les deux dernières zones 10 et 11. Les écartements 13 et 14 sont ici sensiblement identique, dans la mesure où la mèche a été enroulée selon une spire régulière autour du support 1, et dans la mesure où le produit a été déposé selon une bande parallèle à l'axe d'allongement principal X, où mais cela pourrait être différent en faisant varier l'enroulement ou le dépôt du produit capillaire. These zones 9, 10 and 11 have substantially the same height 12 relative to the length of the wick. Depending on how the hair product is applied on the outer periphery of the support 1, these areas could have different lengths. Furthermore, there is a first spacing 13 between the two first zones 9 and 10, and a second spacing 14 between the last two zones 10 and 11. The spacings 13 and 14 are here substantially identical, in the measure that the wick was wound in a regular turn around the support 1, and insofar as the product has been deposited in a strip parallel to the axis main elongation X, where but it could be different by varying winding or depositing the hair product.

La figure 3 présente un support 20 également cylindrique, et de préférence également réalisé dans un matériau élastiquement déformable, pour être utilisé dans le procédé selon l'invention. Dans cette variante, des encoches 21 et 22 pour retenir la portion de mèche enroulée autour du support 20 sont réalisées dans des plans perpendiculaires à l'axe d'allongement principal X. Ces encoches 21 et 22 présentent chacune une fente au niveau du pourtour extérieur 23 du cylindre, ces fentes ne débouchant pas au niveau des faces de base 24 et de sommet 25. Les encoches sont en particulier parallèles entre elles, et parallèles à ces base 24 et sommet 25, et réalisées respectivement à proximité de ces faces 24 et 25 pour optimiser la longueur de support 20 au niveau de laquelle la mèche peut être enroulée. Ces encoches 21 et 22 peuvent également être élastiquement déformables.FIG. 3 shows a support 20 also cylindrical, and preferably also made of an elastically deformable material, to be used in the process according to the invention. In this variant, notches 21 and 22 for retain the portion of wick wrapped around the support 20 are produced in planes perpendicular to the main elongation axis X. These notches 21 and 22 each have a slot at the outer periphery 23 of the cylinder, these slots not opening at the base 24 and top 25 faces. notches are in particular parallel to each other, and parallel to these bases 24 and vertex 25, and produced respectively near these faces 24 and 25 for optimize the support length 20 at which the drill bit can be wound. These notches 21 and 22 can also be resiliently deformable.

Alternativement, la figure 4 présente une autre variante de réalisation d'un support 30 pour être utilisé dans le procédé selon l'invention. Dans cette autre variante, le support 30 est également cylindrique et comporte plusieurs fentes 31, 32, 33, 34 et 35 définies au niveau du pourtour extérieur 36 du support, éventuellement parallèles entre elles, et éventuellement formant un angle avec l'axe d'allongement principal X du support 30. Ces fentes ne débouchent pas au niveau des faces de base 37 et de sommet 38 qui sont elles orthogonales à l'axe X. Ces fentes ou encoches 31, 32, 33, 34 et 35 peuvent également être élastiquement déformables pour y retenir une portion de mèche.Alternatively, Figure 4 shows another alternative embodiment of a support 30 to be used in the method according to the invention. In this other variant, the support 30 is also cylindrical and has several slots 31, 32, 33, 34 and 35 defined at the outer periphery 36 of the support, possibly parallel to each other, and possibly forming an angle with the main elongation axis X of the support 30. These slots do not open out at the level of the base 37 and vertex 38 faces which are orthogonal to the axis X. These slots or notches 31, 32, 33, 34 and 35 can also be elastically deformable to retain a portion of wick therein.

La multiplicité des fentes permet de retenir en plusieurs points la mèche enroulée autour du support 30, et ainsi de créer des boucles éventuellement plus lâches et non destinées à être enduites de produit. De même, cette autre variante rend le support 30 plus adapté à la diversité des longueurs des mèches à traiter sur une même tête ou d'une utilisatrice à l'autre, dans le cas où les supports seraient réutilisés.The multiplicity of slots makes it possible to retain the wick at several points wrapped around the support 30, and thus create possibly more loops loose and not intended to be coated with product. Similarly, this other variant makes the support 30 more suitable for the diversity of the lengths of the strands to be treated on the same head or from one user to another, in the case where the supports would be reused.
