Description

Procédé d'élaboration d'un élément d'assemblaqe non permanent et élémentProcess for producing a non-permanent assembly element and element

d'assemblaqe obtenu par ce procédé  of assembly obtained by this process

La présente invention concerne un 'procédé d'élaboration d'un élément d'assemblage non permanent, du type formé d'un fourreau logeant au moins un élément magnétique ainsi que l'élément d'assemblage obtenu par le procédé.  The present invention relates to a method of producing a non-permanent joining element, of the type formed of a sheath housing at least one magnetic element and the assembly element obtained by the method.

L'invention concerne plus particulièrement un élément d'assemblage destiné à io coopérer avec un élément d'assemblage complémentaire, notamment pour la réalisation de fermeture, en particulier de pièces de vêtement ou autre.  The invention more particularly relates to an assembly element intended to cooperate with a complementary connecting element, in particular for the realization of closure, in particular of garment parts or other.

Les éléments d'assemblage, notamment pour la réalisation de dispositif de fermeture magnétique du type mentionné ci-dessus, sont bien connus à ceux is versés dans cet art comme l'illustre en particulier le brevet FR-A-2.786.669 dans lequel il est décrit un fourreau logeant avec jeu une barrette d'aimants pour permettre en particulier un réglage de la fermeture.  The assembly elements, in particular for the realization of magnetic closure device of the type mentioned above, are well known to those skilled in the art as illustrated in particular in FR-A-2,786,669 in which it is described a sleeve housing with play a bar of magnets to allow in particular a setting of the closure.

Les difficultés de tels éléments d'assemblage résident dans leur fabrication automatisée en série. Jusqu'à présent, les techniques mises en oeuvre consistent soit en un assemblage par couture des faces du fourreau, soit en un assemblage par soudure par ultrasons des faces découpées du fourreau. Dans le premier cas, l'opération d'assemblage est fastidieuse engendrant un temps de fabrication trop important et un résultat inesthétique. Dans le second cas, la soudure présente une résistance mécanique insuffisante et on constate dans le temps une usure prématurée, en particulier par déchirement du fourreau. Lorsque la soudure est renforcée, elle amène alors à une rigidité de l'élément d'assemblage qui rend cet élément inconfortable et coupant au niveau des bords lors d'un contact avec la peau, en particulier dans le cas d'une application à des pièces de lingerie, telles que soutien-gorge, le dispositif de fermeture étant alors utilisé pour permettre la fermeture dudit soutien-gorge.  The difficulties of such assembly elements reside in their automated series production. Until now, the techniques used consist either of a sewing assembly of the faces of the sheath, or of an assembly by ultrasonic welding of the cut faces of the sheath. In the first case, the assembly operation is tedious generating too much manufacturing time and unsightly result. In the second case, the weld has insufficient mechanical strength and there is a premature wear over time, in particular by tearing the sheath. When the weld is reinforced, it then leads to a rigidity of the connecting element which makes this element uncomfortable and cutting at the edges during contact with the skin, particularly in the case of an application to lingerie parts, such as bra, the closure device then being used to allow the closure of said bra.

Par ailleurs, comme l'assemblage par soudure par ultrasons s'opère sur des pièces préalablement découpées à un autre poste, on constate fréquemment des décalages entre lesdites faces ou des malfaçons rendant impossible une fabrication industrielle en série.  Moreover, as the assembly by ultrasonic welding is performed on parts previously cut to another station, there are frequently shifts between said faces or poor workmanship making it impossible to industrial manufacture in series.

Un but de la présente invention est donc de proposer un procédé d'élaboration d'un élément d'assemblage du type précité dont les étapes permettent une mise en oeuvre rapide, à faible coût tout en obtenant une bonne reproductibilité au niveau des éléments d'assemblage obtenus.  An object of the present invention is therefore to propose a method for producing an assembly element of the above-mentioned type, the steps of which make it possible to implement it quickly, at low cost while obtaining good reproducibility at the level of the elements of the invention. assembly obtained.

Un autre but de la présente invention est de proposer un procédé d'élaboration d'un élément d'assemblage dont la mise en oeuvre permet l'obtention d'un élément d'assemblage confortable, en particulier lors d'une application à des pièces de lingerie, telles que soutien-gorge.  Another object of the present invention is to propose a method for producing an assembly element whose implementation makes it possible to obtain a comfortable assembly element, in particular when applied to parts. lingerie, such as bra.

A cet effet, l'invention a pour objet un procédé d'élaboration d'un élément d'assemblage non permanent, du type formé d'un fourreau logeant au moins un élément magnétique, cet élément d'assemblage étant destiné à coopérer avec un élément d'assemblage complémentaire, notamment pour la réalisation de fermeture, en particulier de pièces de vêtement ou autre, caractérisé en ce qu'on déroule en continu des bandes de tissu que l'on superpose pour former les faces du fourreau, en ce qu'on immobilise lesdites bandes sur un poste d'assemblage et de découpe et en ce qu'on soumet lesdites bandes audit poste à une opération d'assemblage par soudure et à une opération de découpe du contour du fourreau, au moins un élément magnétique étant introduit entre les faces du fourreau à un stade quelconque de la fabrication dudit fourreau.  For this purpose, the subject of the invention is a process for producing a non-permanent joining element of the type formed of a sleeve housing at least one magnetic element, this connecting element being intended to cooperate with a complementary assembly element, in particular for the realization of closure, in particular of garment parts or the like, characterized in that strips of fabric are unwound continuously and superposed to form the faces of the sheath, in that said strips are immobilized on an assembly and cutting station and in that said strips are subjected to said station to an assembly operation by welding and to a cutting operation of the outline of the sleeve, at least one magnetic element being introduced between the faces of the sheath at any stage of the manufacture of said sheath.

Grâce à la mise en oeuvre en un même poste, à la fois d'une opération d'assemblage par soudure et d'une opération de découpe du contour du fourreau, on obtient une grande résistance mécanique du fourreau réalisé sans nuire à la souplesse de la pièce. Cette mise en oeuvre des différentes étapes permet en outre de travailler de manière rapide et fiable en obtenant des éléments d'assemblage identiques, d'un élément d'assemblage à un autre.  Thanks to the implementation in the same station, both of a welding assembly operation and a cutting operation of the outline of the sheath, one obtains a high mechanical strength of the sheath achieved without harming the flexibility of the room. This implementation of the various steps also makes it possible to work quickly and reliably by obtaining identical assembly elements, from one assembly element to another.

L'invention a encore pour objet un élément d'assemblage non permanent obtenu notamment par mise en oeuvre d'un procédé du type précité, cet élément d'assemblage, du type constitué d'un fourreau logeant au moins un élément magnétique, étant destiné à coopérer avec un élément d'assemblage complémentaire, notamment pour la réalisation de fermeture, en particulier de pièces de vêtement ou autre, caractérisé en ce que les faces du fourreau sont pourvues d'une première ligne de soudure servant à délimiter l'espace de lo réception de l'élément magnétique et d'une seconde ligne de soudure délimitant le contour du fourreau, cette seconde ligne de soudure étant écartée de la première ligne de soudure de manière à former entre lesdites lignes une marge exempte de soudure pour constituer, au voisinage de la seconde ligne de soudure, une zone souple de confort.  The invention also relates to a non-permanent assembly element obtained in particular by implementing a method of the aforementioned type, this assembly element, of the type consisting of a sleeve housing at least one magnetic element, being intended to cooperate with a complementary connecting element, in particular for the realization of closure, in particular of garment parts or the like, characterized in that the faces of the sheath are provided with a first weld line serving to delimit the space of lo reception of the magnetic element and a second weld line delimiting the contour of the sheath, this second weld line being spaced from the first weld line so as to form between said lines a weld-free margin to constitute, at the neighborhood of the second weld line, a soft zone of comfort.

L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels: la figure 1 représente une vue partiellement en perspective d'un élément 20 d'assemblage conforme à l'invention; la figure 2 représente une vue schématique en coupe d'une installation pour l'élaboration d'un élément d'assemblage conforme à la figure 1; les figures 3 à 5 représentent, sous forme de vues schématiques, les différentes étapes de fabrication d'un élément d'assemblage.  The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which: FIG. 1 represents a partially perspective view of an assembly element according to the invention; FIG. 2 is a diagrammatic sectional view of an installation for producing an assembly element according to FIG. 1; Figures 3 to 5 show, in schematic views, the various steps of manufacturing an assembly element.

Comme mentionné ci-dessus, l'invention a pour objet l'élaboration d'un élément 1 d'assemblage non permanent, du type formé d'un fourreau 2 logeant au moins un élément magnétique. Cet élément 1 d'assemblage est destiné à coopérer avec un élément d'assemblage complémentaire, notamment pour la réalisation de fermeture, en particulier de pièces de vêtement, telles que des pièces de lingerie.  As mentioned above, the invention relates to the development of a non-permanent assembly member 1, of the type formed of a sleeve 2 housing at least one magnetic element. This element 1 assembly is intended to cooperate with a complementary connecting element, in particular for the realization of closure, in particular garment parts, such as lingerie parts.

Pour l'élaboration d'un élément 1 d'assemblage du type ci-dessus, on procède de la manière suivante. On déroule en continu des bandes 3, 4, 5 de tissu que l'on superpose pour former les faces du fourreau 2. On immobilise lesdites bandes sur un poste 6 d'assemblage et de découpe. On soumet lesdites bandes 3, 4, 5 au poste 6 à une opération d'assemblage par soudure et à une opération de découpe du contour du fourreau 2. On introduit en outre, à un stade quelconque de la fabrication du fourreau 2, au moins un élément o magnétique entre les faces du fourreau 2. Ainsi, cette introduction peut s'opérer lors de la phase de déroulement en continu des bandes de tissu. Elle peut encore s'opérer pendant les étapes d'assemblage et de découpe ou après l'assemblage et la découpe à l'issue de la fabrication du fourreau.  For the elaboration of an assembly element 1 of the above type, the procedure is as follows. Strips 3, 4, 5 of fabric are unrolled continuously and are superimposed to form the faces of the sheath 2. These strips are immobilized on an assembly and cutting station 6. Said strips 3, 4, 5 are subjected at station 6 to a welding assembly operation and to a cutting operation of the outline of sleeve 2. At least one stage of manufacture of sleeve 2 is introduced, at least a magnetic element between the faces of the sleeve 2. Thus, this introduction can occur during the continuous unwinding phase of the fabric strips. It can still occur during the assembly and cutting steps or after assembly and cutting at the end of the manufacture of the sheath.

Les opérations de soudure et de découpe sont réalisées par ultrasons. De ce fait, la découpe permet de réaliser simultanément une première soudure des bords du fourreau, cette première soudure étant renforcée par la soudure réalisée au moment de la fermeture du fourreau. On obtient ainsi une résistance mécanique accrue de l'élément d'assemblage.  The welding and cutting operations are performed by ultrasound. As a result, the cut makes it possible to simultaneously perform a first welding of the edges of the sheath, this first weld being reinforced by the weld made at the time of closure of the sheath. This gives an increased mechanical strength of the connecting element.

A la figure 1, on soude par ultrasons les bandes 3, 4, 5 destinées à constituer les faces du fourreau 2 pour délimiter, par une première ligne 13 de soudure, l'espace de réception de l'élément magnétique. On découpe le contour du fourreau 2 en ménageant une seconde ligne 14 de soudure écartée de la première ligne 13 de soudure de manière à former, entre lesdites lignes 13, 14, une marge 15 exempte de soudure pour constituer, au voisinage de la seconde ligne 14 de soudure, une zone souple de confort. En effet, cette réalisation en deux temps de l'élément 1 d'assemblage permet de disposer, au niveau des bords du fourreau, une souplesse qui évite de blesser le porteur d'une pièce de vêtement équipée d'un tel élément d'assemblage.  In FIG. 1, the strips 3, 4, 5 intended to form the faces of the sheath 2 are ultrasonically welded to define, by a first weld line 13, the space for receiving the magnetic element. The contour of the sleeve 2 is cut out by providing a second weld line 14 spaced apart from the first weld line 13 so as to form, between said lines 13, 14, a weld-free margin 15 to form, in the vicinity of the second line 14 welding, a soft zone of comfort. Indeed, this embodiment in two stages of the assembly element 1 makes it possible to have, at the level of the edges of the sheath, a flexibility that avoids injuring the wearer of a piece of clothing equipped with such an assembly element. .

Les opérations de soudure et de découpe peuvent être réalisées simultanément. Toutefois, de préférence, on réalise les opérations de soudure et de découpe successivement. Ainsi, dans un premier temps, on procède à la réalisation de la première ligne 13 de soudure puis, dans un second temps, on découpe le contour du fourreau 2. Ces deux opérations sont réalisées sur un s même poste d'assemblage de manière à éviter toute tension ou traction sur les bandes de tissu qui pourrait générer un décalage desdites bandes et amener à des erreurs dans la fabrication. Par ailleurs, le fait de procéder successivement permet de faire coopérer une même sonotrode 7 avec d'une part, une première empreinte 8 dont la forme correspond à la première ligne de soudure à réaliser, to d'autre part, avec une seconde empreinte, représentée en 9 aux figures, qui correspond à la découpe à réaliser pour délimiter le contour du fourreau. Ces deux empreintes 8, 9 peuvent être chacune actionnées à l'aide d'un vérin et être montées sur un bloc commun déplacé linéairement par l'intermédiaire d'un ensemble moteur/vis sans fin 10, 11 tel que représenté aux figures. A l'aide du moteur 10 et de la vis sans fin 11, les empreintes 8, 9 défilent successivement au-dessus de la sonotrode 7 pour coopérer avec cette dernière par l'intermédiaire des vérins qui amènent chaque empreinte au voisinage de la sonotrode 7. Le fait d'utiliser deux outils ou empreintes différenciés, l'un pour la découpe, l'autre pour la soudure, permet de faciliter le réglage de la puissance des ultrasons. En effet, cette puissance est différente pour réaliser l'opération de soudure et l'opération de découpe.  The welding and cutting operations can be performed simultaneously. However, preferably, the welding and cutting operations are carried out successively. Thus, in a first step, the first weld line 13 is made and then, in a second step, the outline of the sleeve 2 is cut. These two operations are performed on a same assembly station so as to to avoid any tension or tension on the strips of fabric which could generate an offset of said strips and lead to errors in the manufacture. Furthermore, the fact of proceeding successively makes it possible to cooperate the same sonotrode 7 with on the one hand, a first imprint 8 whose shape corresponds to the first weld line to be produced, and on the other hand, with a second imprint, represented in 9 in the figures, which corresponds to the cut to be made to delimit the outline of the sheath. These two indentations 8, 9 can each be actuated by means of a jack and be mounted on a common block moved linearly via a motor / worm assembly 10, 11 as shown in the figures. With the aid of the motor 10 and the worm 11, the impressions 8, 9 pass successively above the sonotrode 7 to cooperate with the latter through the cylinders which bring each footprint in the vicinity of the sonotrode 7 Using two tools or differentiated fingerprints, one for cutting, the other for welding, makes it easier to adjust the power of the ultrasound. Indeed, this power is different to perform the welding operation and the cutting operation.

Comme l'illustre l'installation représentée à la figure 2, la fabrication d'un élément d'assemblage peut être effectuée en un temps extrêmement court. En effet, les bandes 3, 4, 5 de tissu issues chacune d'une bobine défilent à travers un guide ourleur 18 puis sont entraînées en déplacement par l'intermédiaire de rouleaux rotatifs tangents représentés en 17 aux figures jusqu'au poste 6 d'assemblage. Les bandes s'étendent alors à l'aplomb de la sonotrode 7 qui coopère successivement avec les empreintes de soudure et de découpe représentées en 8, 9 aux figures.  As illustrated in the installation shown in Figure 2, the manufacture of an assembly element can be performed in an extremely short time. Indeed, the strips 3, 4, 5 of fabric each from a reel pass through a hemmer guide 18 and are then driven in displacement by means of tangential rotating rollers shown at 17 in the figures to position 6 of assembly. The strips then extend vertically above the sonotrode 7 which cooperates successively with the weld and cutouts shown at 8, 9 in the figures.

Avant immobilisation des bandes 3, 4, 5 au poste 6 d'assemblage et de découpe, on replie l'un des bords longitudinaux des bandes 3, 4, 5, c'est-à-dire un bord parallèle au sens D de déplacement des bandes, pour former un ourlet 16 avec interposition d'un matériau 12 en feuille non thermocollant, issu de préférence d'une bande bobinée. Cet ourlet 16 est destiné au raccordement de l'élément 1 d'assemblage à la pièce à équiper d'un tel élément. Le repliement de l'un des bords longitudinaux des bandes 3, 4, 5 est obtenu par l'ourleur représenté en 18 à la figure 2. L'insertion du matériau 12 en feuille non thermocollant entre les lèvres de l'ourlet ainsi formé est plus particulièrement visible à la figure 4. Ce matériau 12 en feuille s'insère entre les bords repliés io des bandes et évite ainsi toute soudure entre lesdites bandes.  Before immobilization of the strips 3, 4, 5 at the assembly and cutting station 6, one of the longitudinal edges of the strips 3, 4, 5 is folded, that is to say an edge parallel to the direction D of displacement strips, to form a hem 16 with interposition of a non-heat-sealing sheet material 12, preferably from a wound strip. This hem 16 is intended for connecting the assembly element 1 to the part to be equipped with such an element. The folding of one of the longitudinal edges of the strips 3, 4, 5 is obtained by the hemmer shown at 18 in FIG. 2. The insertion of the material 12 into a non-heat-sealing sheet between the lips of the hem thus formed is more particularly visible in Figure 4. This sheet material 12 is inserted between the folded edges of the strips and thus avoids any welding between said strips.

Ces bandes 3, 4, 5 de tissu sont réalisées en des matériaux thermosoudables, tels que des matériaux en polyamide. Les matériaux en polyamides utilisés ont de préférence une température de fusion similaire. L'une des faces, constituée d'un matériau en polyamide, est généralement doublée extérieurement d'un matériau conférant à la face un aspect de type velours.  These strips 3, 4, 5 of fabric are made of heat-sealable materials, such as polyamide materials. The polyamide materials used preferably have a similar melting temperature. One of the faces, made of a polyamide material, is generally lined externally with a material giving the face a velvet-like appearance.

Comme cela a d'ores et déjà été mentionné ci-dessus, le fait de réaliser deux soudures permet d'augmenter la résistance mécanique du fourreau et d'éviter toute usure prématurée des bords dudit fourreau. Ces faces du fourreau sont soudées l'une à l'autre par deux soudures dont l'une a servi en outre à la découpe du fourreau. Généralement, la première ligne 13 de soudure, qui sert à délimiter l'espace de réception du ou des aimants, affecte la forme générale d'un U. A l'état achevé, le fourreau 2 est ouvert à l'une de ses extrémités et est muni le long de son bord ouvert d'un ourlet 16 destiné au raccordement de l'élément 1 d'assemblage à la pièce à équiper d'un tel élément 1. Ce raccordement s'opère généralement par couture. Les bords de l'ourlet viennent en fait enserrer la partie de la pièce de vêtement sur laquelle ils doivent être rapportés.  As already mentioned above, the fact of making two welds makes it possible to increase the mechanical strength of the sheath and to avoid any premature wear of the edges of said sheath. These sides of the sheath are welded to one another by two welds, one of which was also used to cut the sheath. Generally, the first weld line 13, which serves to delimit the reception space of the magnet or magnets, affects the general shape of a U. In the completed state, the sleeve 2 is open at one of its ends. and is provided along its open edge with a hem 16 for connecting the assembly element 1 to the part to be equipped with such an element 1. This connection is generally made by sewing. The edges of the hem actually enclose the part of the piece of clothing on which they must be reported.

Le procédé tel que décrit ci-dessus, mis en oeuvre au moyen d'une installation conforme par exemple à celle représentée à la figure 2, permet une fabrication automatisée et en série des éléments 1 d'assemblage en un temps relativement court et ce de manière reproductible.  The method as described above, implemented by means of an installation conforming for example to that shown in FIG. 2, allows an automated and series production of the assembly elements 1 in a relatively short time and this reproducible way.
