Sur les figures 1 à 3, on a représenté un ensemble tige-première conforme à l'invention d'une mule ouverte à l'avant. La première est intégrée à la tige dont elle constitue un prolongement réalisé par une découpe approprié d'un matériau monocouche ou d'un complexe multi-matériaux.In Figures 1 to 3, there is shown a rod-first assembly according to the invention of a mule open at the front. The first is integrated in the rod which it constitutes an extension made by a suitable cut of a monolayer material or a multi-material complex.

Les matériaux peuvent être quelconques tels que tissu, feutre, intissé, mousse, etc... en matière naturelle ou synthétique.The materials may be any such as fabric, felt, nonwoven, foam, etc ... of natural or synthetic material.

La découpe représentée en figure 1 fait apparaître une partie centrale 1 formant la tige de l'article chaussant et flanquée, au-delà des lignes en pointillés, d'un côté, d'un premier prolongement 2a et, de l'autre côté, d'un second prolongement 2b. Les bords avant et arrière de la tige 1 peuvent être simplement rabattus ou munis, comme représenté en 3, d'une bordure décorative.The cutout shown in FIG. 1 shows a central portion 1 forming the upper of the article of footwear and flanked, beyond the dotted lines, on one side, a first extension 2a and, on the other side, a second extension 2b. The front and rear edges of the rod 1 can simply be folded down or provided, as shown in 3, with a decorative border.

Les prolongements 2a, 2b ont un contour complémentaire en sorte qu'en les faisant s'épouser le long d'une ligne de jonction bord à bord 4 (figure 2), lesdits prolongements 2a, 2b, par rabattement pour les mettre dans un même plan, délimitent et constituent la première comme on peut l'observer sur la figure 2 qui représente, côté semelle, l'ensemble tige 1-première 2a, 2b.The extensions 2a, 2b have a complementary contour so that by marrying them along an edge-to-edge joining line 4 (FIG. 2), said extensions 2a, 2b, by folding to put them in the same plane, delimit and constitute the first as can be seen in Figure 2 which represents, sole side, the entire stem 1-first 2a, 2b.

La ligne de jonction 4 est définie par le rapprochement bord à bord respectivement (figure 1) des bords 4a du prolongement 2a et 4b du prolongement 2b.The junction line 4 is defined by the edge-to-edge approach respectively (FIG. 1) of the edges 4a of the extension 2a and 4b of the extension 2b.

La ligne de jonction 4 a une forme de S et joint les deux flancs de l'ensemble tige-première une fois monté.The junction line 4 has an S shape and joins the two sides of the rod-first assembly once mounted.

Le prolongement 2a constitue de manière prédominante la zone sous-plantaire de la première, cependant que le prolongement 2b constitue de manière prédominante la zone en regard du talon.The extension 2a is predominantly the subplantar zone of the first, while the extension 2b is predominantly the area facing the heel.

La forme de la jonction 4 peut bien entendu varier dans de larges mesures, mais doit faciliter à la fois la découpe de la pièce (1, 2a, 2b) et son montage.The shape of the junction 4 can of course vary widely, but must facilitate both the cutting of the part (1, 2a, 2b) and its mounting.

Sur la figure 4 est représentée une semelle 5 vue côté intérieur et destinée à l'ensemble tige-première de la figure 3.FIG. 4 shows a sole 5 viewed on the inside and intended for the entire stem-first assembly of FIG.

La semelle 4 est par exemple une semelle en matériau moulé sous pression, par exemple en élastomère, plate ou munie d'un talon, à épaisseur évolutive ou non et présentant ou non un rebord périphérique vertical (semelle de type barquette).The sole 4 is for example a sole of die-cast material, for example elastomer, flat or with a heel, scalable or not and optionally having a vertical peripheral edge (tray-type sole).

En tiretés 6 est représenté symboliquement l'emplacement de la ligne de jonction 4 de l'ensemble tige 1-première 2a, 2b lorsque la semelle sera en place sur la première.In dashed lines 6 is represented symbolically the location of the junction line 4 of the first 1-first rod assembly 2a, 2b when the soleplate is in place on the first.

En 7, sont représentés deux minces cordons de colle hot-melt, disposés parallèlement de part et d'autre de la ligne 6 et destinées au collage des bords 4a, 4b des prolongements 2a, 2b sur la semelle 5.In FIG. 7, two thin strips of hot melt glue, arranged parallel to each other on either side of the line 6, are shown for bonding the edges 4a, 4b of the extensions 2a, 2b to the soleplate 5.

Sur la figure 4, on n'a pas représenté le cordon de collage du pourtour de la première sur la semelle 5, ce cordon étant bien entendu disposé sur tout le pourtour intérieur de la semelle à la manière habituelle.In Figure 4, there is not shown the bead of the periphery of the first on the sole 5, this bead being of course disposed over the entire inner periphery of the sole in the usual manner.

La partie arrière de la semelle 5 peut avoir une épaisseur plus importante et être pourvue, intérieurement, d'alvéoles à la manière connue. Dans le cas où une partie des cordons de colle 7 empièterait sur une zone à alvéoles il serait préférable de ne pas former au moulage de la semelle d'alvéoles dans la zone de dépose desdits cordons 7.The rear part of the sole 5 may have a greater thickness and be internally provided with cavities in the known manner. In the case where a portion of the adhesive beads 7 would encroach on a zone with cells it would be preferable not to mold the soleplate in the area where said beads 7 are deposited.

Dans la variante d'article chaussant des figures 5 et 6, la tige 1' est une tige de mule fermée à l'avant.In the footwear variant of Figures 5 and 6, the rod 1 'is a mule rod closed at the front.

En 2a' et 2b' sont représentés des prolongements latéraux de la tige 1' homologues des prolongements 2a, 2b de la figure 1, avec leurs bords respectifs 4a' et 4b' qui viendront au montage se positionner en regard de manière jointive.In 2a 'and 2b' are shown lateral extensions of the rod 1 'homologous extensions 2a, 2b of Figure 1, with their respective edges 4a' and 4b 'which will come to the mounting position facing contiguously.

Du fait de l'existence d'une claque avant fermée (1') lesdits prolongements 2a' et 2b' sont eux-mêmes prolongés en partie avant de pattes 8 et 9 respectivement, séparées de la tige 1' par une ligne de découpe, respectivement 10 et 11.Due to the existence of a closed front slam (1 '), said extensions 2a' and 2b 'are themselves extended in front of tabs 8 and 9, respectively, separated from the rod 1' by a cutting line, respectively 10 and 11.

La première étape de montage de l'ensemble tige 1'-première 2a', 2b' consiste comme illustré par la figure 6, à réaliser une couture bord à bord des parties 8 et 9 à la fois entre elles (couture 12) et avec le bord avant 13 de la tige 1' (couture 14).The first assembly step of the first shaft assembly 2a ', 2b' consists, as illustrated in FIG. 6, of edge-to-edge sewing. parts 8 and 9 at a time between them (seam 12) and with the front edge 13 of the shank 1 '(seam 14).

La figure 7 montre la mise en forme de l'ensemble tige 1'-première (2a', 2b'), après réalisation des coutures 12, 14. En 4' est représentée la ligne de jonction des bords 4a', 4b' des prolongements 2a', 2b' définissant la première.FIG. 7 shows the shaping of the entire rod 1-first (2a ', 2b'), after making the seams 12, 14. In 4 'is shown the line joining the edges 4a', 4b 'of extensions 2a ', 2b' defining the first.

La figure 8 est une figure homologue de la figure 4 représentant une semelle 5' destinée au montage de l'ensemble tige-première de la figure 7 et munie de deux cordons de colle parallèles 7' en regard de la ligne de jonction 4' des parties de la première 2a', 2b'.FIG. 8 is a counterpart of FIG. 4 showing a sole 5 'intended for mounting the first-rod assembly of FIG. 7 and provided with two parallel glue strips 7' facing the connecting line 4 'of the parts of the first 2a ', 2b'.

Sur la figure 9 est illustrée une autre variante dans laquelle la première n'est constituée qu'en partie par des prolongements en bords rabattus, respectivement 15 et 16, d'une tige 1" d'une mule ouverte à l'avant.In Figure 9 is illustrated another variant in which the first is formed in part by extensions folded edges, respectively 15 and 16, a rod 1 "of a mule open at the front.

Dans le mode de réalisation représenté, lesdits prolongements 15, 16 sont en forme de bandes agencées sur les flancs de la tige 1". La première est complétée par une partie 17 dont le contour est déterminé de façon à délimiter en complément avec les bandes 15, 16 ladite première en correspondance avec la semelle 5" qui est, ici, une semelle du type barquette dont on a représenté en 18 le bord périphérique relevé. Les parties 15, 16, 17 sont de niveau et bord à bord.In the embodiment shown, said extensions 15, 16 are in the form of strips arranged on the sides of the rod 1 ".The first is completed by a portion 17 whose contour is determined so as to delimit in complement with the strips 15 , Said first in correspondence with the sole 5 "which is, here, a tray-type sole which has been shown in 18 the raised peripheral edge. Parts 15, 16, 17 are level and edge to edge.

La solidarisation des trois parties de l'article chaussant, à savoir tige 1", partie de première 17 et semelle 5" est assurée à l'aide de cordons de colle disposés sur la face interne de la semelle sur la périphérie ainsi qu'à hauteur des lignes de séparation des parties 15, 16 et 17, de manière analogue à celle décrite plus haut à propos des modes de réalisation des figures précédentes. Bien évidemment l'assemblage des trois parties de l'article chaussant peut être réalisé par tout autre moyen adéquatement choisi en fonction de la nature des parties considérées : clouage, soudure, couture, ...The joining of the three parts of the article of footwear, namely shank 1 ", part of the first 17 and sole 5" is ensured by means of adhesive beads arranged on the inner face of the sole on the periphery as well as height of the separation lines of the parts 15, 16 and 17, in a manner similar to that described above with respect to the embodiments of the preceding figures. Of course, the assembly of the three parts of the footwear can be achieved by any other means suitably chosen depending on the nature of the parts considered: nailing, welding, sewing, ...

Il est à noter que la variante de la figure 9 peut s'appliquer à des mules fermées à l'avant.It should be noted that the variant of FIG. 9 can be applied to closed mules at the front.

On va maintenant décrire le procédé conforme à l'invention de montage des articles chaussants qui viennent d'être décrits en se reportant aux figures 10 à 14.We will now describe the method according to the invention for mounting footwear which have just been described with reference to Figures 10 to 14.

Conformément à l'invention, on monte l'ensemble tige-première sur une forme spéciale représentée en 19 sur la figure 11 et qui est une structure creuse susceptible d'être mise en dépression en étant reliée par une gaine 20 à une source d'aspiration 21, par exemple une pompe à vide, munie de moyens de commande 22.In accordance with the invention, the stem-first assembly is mounted on a special form represented at 19 in FIG. 11 and which is a hollow structure capable of being depressed by being connected by a sheath 20 to a suction source 21, for example a vacuum pump, provided with control means 22.

La face 19a de la forme 19 délimitant la semelle de l'article chaussant à monter est pourvue d'orifices 23 faisant communiquer l'intérieur de la forme avec l'extérieur.The face 19a of the shape 19 delimiting the sole of the footwear to be mounted is provided with orifices 23 communicating the inside of the shape with the outside.

Dans un mode de réalisation particulier, la forme qui comporte également des bords latéraux, présente des orifices d'aspiration non seulement sur la face 19a de la forme délimitant la semelle mais également sur ces bords latéraux de manière à plaquer la tige contre ladite forme 19. Avantageusement, l'outillage peut comporter également des moyens permettant d'obturer les orifices d'aspiration qui ne seraient pas couverts par un élément de l'article chaussant. Ces moyens comprennent par exemple des éléments en plastique comportant une partie plane et souple destinée à couvrir un ou plusieurs orifices non couverts. Cette partie plane est destinée à épouser la structure locale de la forme 19. Ces moyens peuvent comporter de plus un ou plusieurs ergots destinés à être insérés dans lesdits orifices non couverts afin de simplifier le positionnement et faciliter la tenue de ces moyens lorsque la source d'aspiration n'est pas en fonctionnement.In a particular embodiment, the shape which also has side edges, has suction openings not only on the face 19a of the shape delimiting the sole but also on these side edges so as to press the rod against said shape 19 Advantageously, the tooling may also include means for closing the suction orifices that would not be covered by an item of the article of footwear. These means comprise for example plastic elements having a flat and flexible portion intended to cover one or more uncovered orifices. This flat part is intended to fit the local structure of the form 19. These means may further comprise one or more lugs intended to be inserted into said uncovered orifices to simplify the positioning and facilitate the holding of these means when the source of suction is not in operation.

Les orifices 23 sont répartis de préférence régulièrement à la périphérie de la face 19a. La taille, le nombre et le mode de distribution des orifices peuvent bien entendu varier selon le type d'article chaussant et la configuration des parties constitutives de la première.The orifices 23 are preferably distributed regularly at the periphery of the face 19a. The size, the number and the mode of distribution of the orifices can of course vary according to the type of footwear and the configuration of the constituent parts of the first.

On a représenté en outre en 24 des orifices un peu plus petits que les orifices 23 et agencés dans l'espace intérieur délimité par ces derniers et destinés à éventuellement parfaire le plaquage, comme on le comprendra plus loin, desdites parties constitutives de la première contre la face 19a de la forme.There are also shown at 24 holes a little smaller than the orifices 23 and arranged in the interior space delimited by them and intended to eventually perfect the plating, as will be understood later, said constituent parts of the first against the face 19a of the form.

Les orifices auxiliaires 24 sont bien entendu optionnels.The auxiliary orifices 24 are of course optional.

Les figures 12 à 14 illustrent le montage à l'aide de la forme 19 d'un article chaussant à l'ensemble tige-première selon les figures 5 à 7.Figures 12 to 14 illustrate the fitting with the form 19 of an article of footwear to the rod-first assembly according to Figures 5 to 7.

Après réalisation des coutures 12, 14 conformément à la figure 6, l'ensemble tige 1 '-prolongements 2a', 2b' est placé sur la forme 19 comme illustré par la figure 12, la pointe de l'ensemble étant enfilée sur la pointe de la forme.After making the seams 12, 14 according to FIG. 6, the rod assembly 1 '- extensions 2a', 2b 'is placed on the form 19 as illustrated in FIG. 12, the tip of the assembly being threaded onto the tip of shape.

Dans cette position et après mise en marche du dispositif d'aspiration 20 à 22, les prolongements 2a', 2b' sont rabattus vers la face aspirante 19a de la forme en positionnant manuellement bord à bord (figure 13) lesdits prolongements. Un plaquage particulièrement aisé, précis, rapide et stable est ainsi obtenu grâce au vide partiel réalisé à l'intérieur de la forme.In this position and after starting the suction device 20 to 22, the extensions 2a ', 2b' are folded towards the suction face 19a of the form by manually positioning edge-to-edge (Figure 13) said extensions. A plating particularly easy, precise, fast and stable is thus obtained thanks to the partial vacuum made inside the form.

L'étape suivante, illustrée par la figure 14, consiste à assembler à l'ensemble tige-première maintenu plaqué contre la forme, une semelle 5'. Cet assemblage peut avantageusement être réalisé par collage, c'est-à-dire en déposant préalablement sur la surface de la semelle des cordons de colle (7') appropriés. Alternativement, l'assemblage de la semelle 5' et de l'ensemble tige-première peut être réalisé par couture, soudure à haute fréquence ou clouage en fonction des matériaux utilisés pour la semelle et l'ensemble tige-première. Le vide est ensuite coupé et l'article chaussant est retiré de la forme.The next step, illustrated in Figure 14, is to assemble the rod-first assembly held pressed against the shape, a sole 5 '. This assembly can advantageously be achieved by gluing, that is to say by previously laying on the surface of the sole glue beads (7 ') appropriate. Alternatively, the assembly of the sole 5 'and the rod-first assembly can be achieved by sewing, high frequency welding or nailing according to the materials used for the sole and the rod-first assembly. The vacuum is then cut off and the footwear is removed from the shape.

Dans le cas d'une tige conforme à la figure 1, la partie tige 1 est plaquée sur la face inférieure avant de la forme 19 et les bords 2a, 2b sont rabattus sur la face 19a.In the case of a rod according to Figure 1, the rod portion 1 is pressed on the front lower face of the form 19 and the edges 2a, 2b are folded on the face 19a.

Dans le cas d'une tige selon la figure 9, la partie tige 1" est plaquée sur la face inférieure avant de la forme 19, puis les bords 15 et 16 ainsi que la partie complémentaire 17 sont positionnés sur la face 19a.In the case of a rod according to Figure 9, the rod portion 1 "is pressed on the front lower face of the form 19, then the edges 15 and 16 and the complementary portion 17 are positioned on the face 19a.

L'outillage peut comprendre des moyens pour éjecter de l'air au travers une partie au moins des orifices (23, 24) de ladite forme (19). Pour cela, la source d'aspiration est éteinte et les moyens pour éjecter de l'air sont activés par l'opérateur par l'intermédiaire de moyens de commande. Les moyens pour éjecter de l'air comportent une source d'air qui peut générer de l'air chauffé par exemple au moyen d'une résistance. Cet air chauffé peut servir à accélerer le séchage de la colle servant à assembler les trois parties de l'article chaussant. Alternativement, il peut s'agir d'une source générant de l'air refroidi.The tool may include means for ejecting air through at least a portion of the orifices (23, 24) of said shape (19). For this, the suction source is extinguished and the means for ejecting air are activated by the operator via control means. The means for ejecting air comprises a source of air which can generate heated air for example by means of a resistor. This heated air can be used to accelerate the drying of the glue used to assemble the three parts of the article of footwear. Alternatively, it may be a source generating cooled air.

L'air généré par la source peut de plus se présenter sous pression afin de former un jet en sortie des orifices d'aspiration. Ce jet peut alors être utilisé par l'opérateur pour plaquer très simplement des éléments à assembler les uns contre les autres.The air generated by the source can also be under pressure to form a jet output of the suction ports. This jet can then be used by the operator to very simply flatten elements to be assembled against each other.

Le procédé de l'invention permet de réduire substantiellement les temps et les coûts de fabrication des articles chaussants en réduisant le nombre de pièces différentes à confectionner et à assembler et en supprimant au maximum les assemblages par couture, remplacés par des assemblages par collage, beaucoup plus rapide à réaliser et susceptibles d'être totalement automatisés, ce qui n'est pas le cas des opérations de couture.The method of the invention makes it possible to substantially reduce the manufacturing time and costs of footwear by reducing the number of different pieces to be made and assembled and by eliminating the stitching assemblies as much as possible, replaced by bonding assemblies, many faster to achieve and likely to be fully automated, which is not the case of sewing operations.
