The invention relates to a method of producing a knitted footwear element, that is to say a knitting method of a footwear element, in particular a shoe element.
Il est connu de réaliser des éléments chaussant, en particulier des chaussures, à partir de parties tricotées. Ces procédés nécessitent de réaliser les parties tricotées, puis d'ajuster leurs dimensions, notamment par découpe avant des les assembler, par exemple par couture ou collage. Cette série d'étapes pose des problèmes. En effet, elles nécessitent des temps importants pour les mettre en œuvre. Par ailleurs, les étapes d'ajustement des dimensions entraînent des pertes de tricot inutilisables. Enfin, les liaisons, notamment les liaisons par coutures sont susceptibles d'entraîner des problèmes d'inconfort pour le porteur de la chaussure. It is known to make footwear elements, especially shoes, from knitted parts. These processes require the knitted parts to be made and then to adjust their dimensions, in particular by cutting them before assembling them, for example by sewing or gluing. This series of steps is problematic. Indeed, they require significant time to implement them. In addition, the dimensional adjustment steps result in unusable knitting losses. Finally, the connections, especially the seam connections are likely to cause discomfort problems for the wearer of the shoe.
Le but de l'invention est de fournir un procédé de réalisation d'un élément chaussant tricoté permettant de remédier aux inconvénients mentionnés précédemment et d'améliorer les procédés connus de l'art antérieur. En particulier, l'invention propose un procédé de réalisation d'un élément chaussant tricoté simple, rapide et économique permettant d'éviter des pertes de tricot et d'améliorer le confort des chaussures pour leur porteur.

Sur la figure 2, on a représenté un plan P au moins sensiblement vertical et au moins sensiblement longitudinal et la trace 1 13 de ce plan P sur l'élément chaussant. Ce plan peut être remplacé par toute surface gauche permettant de délimiter une partie droite 101 d de l'élément chaussant et une partie gauche 101 g de l'élément chaussant, la partie droite de l'élément chaussant étant tricotée, notamment tricotée intégralement, sur une première fonture d'une machine à tricoter et la partie gauche de l'élément chaussant étant tricotée, notamment tricotée intégralement, sur une deuxième fonture de la machine à tricoter. Ainsi, la partie droite de l'élément chaussant comprend un premier élément 1 10d de la tige, un premier élément 1 1 1 d de la languette et un premier élément 1 12d de la semelle et la partie gauche de l'élément chaussant comprend un deuxième élément 1 10g de la tige, un deuxième élément de la languette 1 1 1 g et un deuxième élément 1 12g de la semelle. Preferably, at least one and the same thread (uninterrupted) makes it possible to knit at least a portion of the shank and at least a portion of the tongue and at least one same thread (uninterrupted) makes it possible to knit at least part of the shank and at least a part of the sole. The same yarn may also allow to knit at least a portion of the rod and at least a portion of the tongue and at least a portion of the sole. In Figure 2, there is shown a plane P at least substantially vertical and at least substantially longitudinal and the trace 1 13 of this plane P on the footwear element. This plane may be replaced by any left surface delimiting a right portion 101 d of the footwear element and a left portion 101 g of the footwear element, the right part of the footwear element being knitted, in particular knitted integrally, on a first needle of a knitting machine and the left part of the footwear element being knitted, in particular knitted integrally, on a second needle bed of the knitting machine.

The footwear element further comprises an opening 114 allowing the user to put on the footwear element. This opening is partially closed by the tongue 1 1 1.
Différentes zones de l'élément chaussant, correspondant ou non aux parties évoquées plus haut, peuvent être tricotées avec des fils différents, notamment des fils de dimensions différentes et/ou des fils de matières différentes et/ou des fils d'aspects différents, en particuliers de couleurs différentes. Different zones of the footwear element, which may or may not correspond to the parts mentioned above, may be knitted with different yarns, in particular yarns of different sizes and / or yarns of different materials and / or yarns of different aspects, in particular of different colors.
L'élément chaussant comprend une zone 1 16 dans laquelle des mailles sont alternativement ou successivement formées à l'endroit et à l'envers. Cette zone s'étend sur toute la languette ou sur une partie de la languette et/ou sur une partie supérieure 1 15d, 1 15g de la tige, notamment autour de l'ouverture ou au niveau de l'ouverture. Dans cette zone, on tricote successivement une ou plusieurs mailles à l'endroit et une ou plusieurs mailles à l'envers. Les successions de maille(s) à l'envers et de maille(s) à l'endroit peuvent être réalisées sur chaque ou sur certaines rangées tricotées et/ou sur chaque ou sur certaines colonnes tricotées. The footwear element comprises an area 1 16 in which meshes are alternately or successively formed at the place and upside down. This zone extends over the entire tongue or over part of the tongue and / or on an upper part 15d, 15g of the rod, in particular around of the opening or at the level of the opening. In this zone, one knits successively one or more stitches at the place and one or more stitches in reverse. The succession of mesh (s) upside down and mesh (s) at the place can be performed on each or on some knitted rows and / or on each or on some knitted columns.
Des successions de maille(s) à l'envers et de maille(s) à l'endroit peuvent aussi être réalisées sur chaque ou sur certaines rangées tricotées et/ou sur chaque ou sur certaines colonnes tricotées en tout autre endroit de l'élément chaussant, notamment en tout autre endroit de la tige et/ou de la semelle. Successions of mesh (s) upside down and mesh (s) to the place can also be performed on each or on some knitted rows and / or on each or on some knitted columns in any other place of the element footwear, especially in any other place of the upper and / or the sole.
Pour réaliser l'élément chaussant, on peut bien entendu utiliser tout type de construction tricotée. To achieve the footwear element, one can of course use any type of knitted construction.
Un premier mode d'exécution du procédé selon l'invention permettant de réaliser un élément chaussant selon l'invention est décrit ci-après en référence à la figure 3. Sur cette figure, on représente par exemple la partie droite de l'élément chaussant. A first embodiment of the method according to the invention for producing a footwear element according to the invention is described below with reference to FIG. 3. In this figure, for example, the right part of the footwear element is shown. .
Dans une première étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 201 et 202 à un segment s'étendant entre les points 203 et 204. Ceci permet de former un élément 1 1 1 d de languette. On tricote cet élément sur une première fonture. Toutefois, on tricote simultanément, sur une deuxième fonture, un autre élément 1 1 1 g de languette complémentaire permettant de former intégralement la languette 1 1 1 . Pour ce faire, au niveau du segment 202-204 le ou les fils de tricotage passent d'une fonture à l'autre pour former la languette d'un seul tenant. Pour ce faire des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. La dimension du segment 201 à 206 étant inférieure à la dimension du segment 202-204, on met en œuvre une procédure de tricotage permettant d'obtenir une telle géométrie. Cette procédure est illustrée par le schéma de la figure 6. Dans une deuxième étape, on tricote ou on forme des rangées de mailles ou de boucles de la courbe s'étendant entre les points 205 et 206 à une courbe s'étendant entre les points 207 et 210 via 21 1 . Toutefois, on tricote simultanément, sur une deuxième fonture, un autre élément 1 10g de tige complémentaire permettant de former la tige 1 10. Pour ce faire, au niveau du segment 205-207 le ou les fils de tricotage passent d'une fonture à l'autre pour former la tige d'un seul tenant. Pour ce faire des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. La liaison suivant le segment 206-203 est réalisée par une procédure de type Intarsia. In a first step, knitting or forming rows of stitches or loops of the segment extending between the points 201 and 202 to a segment extending between the points 203 and 204. This makes it possible to form an element 1 1 1 d of tongue. We knit this element on a first needle bed. However, it is knitting simultaneously, on a second needle bed, another element 1 1 1 g of complementary tongue to integrally form the tongue 1 1 1. To do this, at the segment 202-204 or the knitting son pass from one needle to another to form the tongue in one piece. To do this means and procedures are in place to allow the son to change the needle. The size of the segment 201 to 206 being smaller than the segment size 202-204, a knitting procedure is used to obtain such a geometry. This procedure is illustrated by the diagram of FIG. 6. In a second step, knitting or forming rows of stitches or loops of the curve extending between points 205 and 206 to a curve extending between the stitches 207 and 210 via 21 1.

To do this, at the segment 205-207 or the knitting son pass from a needle bed to the other to form the rod in one piece. To do this means and procedures are in place to allow the son to change the needle. The link following segment 206-203 is carried out by an Intarsia type procedure.
Dans ces deux premières étapes, les boucles ou mailles sont formées successivement à l'endroit et à l'envers sur chacune des fontures. Ainsi, on forme une zone 1 16 de tricot n'ayant pas tendance à s'enrouler sur lui-même. Pour ce faire, on utilise de préférence le dispositif décrit dans le document de publication de la demande internationale WO2007/025400.

To do this, at the segment 212-214, the knitting son or yarns pass from one needle bed to another to form the stem. one piece. To do this, means and procedures are put in place to allow the threads to change their needle bed. In a seventh step, we knit or form rows of stitches or loops of the segment extending between the points 214 and 215 to the segment extending between the points 215 and 217. This knitting procedure is for example of the knitting type. reciprocating knitting). However, the other element 1 10g of complementary rod and the other sole element 1 12g are knitted simultaneously on a second needle bed making it possible to form the rod 1 10 and the sole 1 12. To do this, at the level of the curve 214-217, the knitting yarn or son pass from one needle to another to form the rod and sole integrally.

Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 10g de tige complémentaire et l'autre élément de semelle 1 12g permettant de former la tige 1 10 et la semelle 1 12. Dans cette huitième étape, on réutilise des mailles laissées en attente, au niveau du segment 213-203, lors de la cinquième étape. Au niveau du segment 217-218, le fil passe d'une fonture à l'autre. En progressant de gauche à droite, des mailles sont laissées en attente pour utilisation ultérieure à une quatorzième étape. In an eighth step, knitting or forming rows of stitches or loops of the segment extending between the points 213 and 217 to the segment extending between the points 203 and 218. However, one knits simultaneously, on a second needle bed , the other element 1 10g of complementary rod and the other sole member 1 12g for forming the rod 1 10 and the sole 1 12. In this eighth step, reused meshes left waiting at the segment 213 -203, in the fifth step. At segment 217-218, the thread passes from one needle to another. Progressing from left to right, meshes are left on hold for later use at a fourteenth stage.
Dans une neuvième étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 218 et 203 au segment s'étendant entre les points 219 et 204.

Pour ce faire, des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. Dans cette neuvième étape, on réutilise des mailles laissées en attente lors de la première étape et on lie le tricot à ces mailles au niveau du segment 203-204. Ainsi, la languette est liée à cette portion tricotée de la tige. In a ninth step, knitting or forming rows of stitches or loops of the segment extending between the points 218 and 203 to the segment extending between the points 219 and 204.

To do this, at the segment 218-219, the son or knitting pass from one needle bed to another to form the stem and the sole in one piece. To do this, means and procedures are in place to allow the threads to change their needle bed. In this ninth step, we reuse mesh left pending in the first step and bind the knit at these stitches at segment 203-204. Thus, the tongue is linked to this knitted portion of the rod.
Dans une dixième étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 219 et 204 au segment s'étendant entre les points 229 et 220. Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 10g de tige complémentaire et l'autre élément de semelle 1 12g permettant de former la tige 1 10 et la semelle 1 12.

To do this, means and procedures are put in place to allow the threads to change their needle bed.
Dans une onzième étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 221 et 220 au segment s'étendant entre les points 224 et 225. On réduit, au niveau de la ligne 221 -224, la largeur du tricot dans cette étape au fur et à mesure qu'on s'approche de l'extrémité avant de l'élément chaussant. Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 10g de tige complémentaire permettant de former la tige 1 10. Pour ce faire, au niveau du segment 220-225, le ou les fils de tricotage passent d'une fonture à l'autre pour former la tige d'un seul tenant. Pour ce faire, des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. Dans une douzième étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 224 et 225 au segment s'étendant entre les points 224 et 227. Cette procédure de tricotage est par exemple du type tricotage réciproque (en anglais reciprocating knitting). Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 10g de tige complémentaire permettant de former la tige 1 10. Pour ce faire, au niveau de la courbe 225-227, le ou les fils de tricotage passent d'une fonture à l'autre pour former la tige d'un seul tenant. Pour ce faire, des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. In an eleventh step, we knit or form rows of meshes or loops of the segment extending between the points 221 and 220 to the segment extending between the points 224 and 225. We reduce, at the line 221 - 224, the width of the knit in this step as one approaches the front end of the footwear element. However, it is knitted simultaneously, on a second needle bed, the other element 1 10g of complementary rod for forming the rod 1 10. To do this, at the 220-225 segment, the knitting yarn or son pass a needle to the other to form the rod in one piece. To do this, means and procedures are put in place to allow the threads to change their needle bed. In a twelfth step, knitting or forming rows of stitches or loops of the segment extending between points 224 and 225 at segment extending between points 224 and 227. This knitting procedure is for example reciprocating knitting type (in English reciprocating knitting). However, it is knitted simultaneously, on a second bed, the other element 1 10g of complementary rod for forming the rod 1 10. To do this, at the 225-227 curve, the knitting yarn or son of one needle to another to form the stem in one piece. To do this, means and procedures are put in place to allow the threads to change their needle bed.
Dans une treizième étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 224 et 227 au segment s'étendant entre les points 221 et 229. On augmente, au niveau de la ligne 221 -224, la largeur du tricot dans cette étape au fur et à mesure qu'on s'éloigne de l'extrémité avant de l'élément chaussant. Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 10g de tige complémentaire et l'autre élément 1 12g de semelle complémentaire permettant de former la tige 1 10 et la semelle. Pour ce faire, au niveau du segment 227-229, le ou les fils de tricotage passent d'une fonture à l'autre pour former la tige d'un seul tenant. Pour ce faire, des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. Dans cette treizième étape, on réutilise des mailles laissées en attente lors de la onzième étape et on lie le tricot à ces mailles, au niveau du segment 221 -224. In a thirteenth step, we knit or form rows of meshes or loops of the segment extending between the points 224 and 227 to the segment extending between the points 221 and 229. We increase, at the line 221 - 224, the width of the knit in this step as one moves away from the front end of the footwear element. However, the other element 1 10g of complementary rod is knitted simultaneously on a second needle bed and the other element 1 12g of complementary soleplate makes it possible to form the rod 1 10 and the soleplate. To do this, at the segment 227-229, the knitting son or son pass from one needle to another to form the rod in one piece. To do this, means and procedures are put in place to allow the threads to change their needle bed. In this thirteenth step, we reuse meshes left pending in the eleventh step and bind the knit at these meshes, at segment 221-224.
Dans une quatorzième étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 221 et 229 au point 228. Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 10g de tige complémentaire et l'autre élément 1 12g de semelle complémentaire permettant de former la tige 1 10 et la semelle. Au niveau du segment 221 -228, les mailles sont connectées aux mailles laissées en attente en fin de dixième étape. Au niveau du segment 221 -229, les mailles sont connectées aux mailles de l'étape précédente. Alors que les aiguilles des deux fontures sont de préférence utilisées dans leurs positions illustrées à la figure 7 dans les première à quatorzième étapes, dans une quinzième étape, on positionne des aiguilles des première et deuxième fontures dans une position relevée illustrée à la figure 8. Ainsi, on tricote ou on forme des rangées de mailles ou de boucles selon le segment 217-219 en réutilisant des mailles laissées en attente dans les étapes précédentes et en liant le tricot à ces mailles. On utilise de préférence un fil en matériau thermoplastique, comme par exemple du PVC. On lie ainsi des éléments 1 12d et 1 12g de semelle formés précédemment et on ferme la partie inférieure de l'élément chaussant. In a fourteenth step, knitting or forming rows of stitches or loops of the segment extending between the points 221 and 229 at the point 228. However, the other element 1 10 g is knitted simultaneously on a second needle bed. complementary rod and the other element 1 12g of complementary sole to form the rod 1 10 and the sole. At segment 221 -228, the links are connected to meshes left waiting at the end of the tenth step. At segment 221 -229, the stitches are connected to the stitches of the previous step. While the needles of the two needle beds are preferably used in their positions illustrated in Figure 7 in the first to fourteenth steps, in a fifteenth step, needles of the first and second needle beds are positioned in a raised position illustrated in Figure 8. Thus, we knit or form rows of stitches or loops according to the segment 217-219 by reusing stitches left pending in the previous steps and by bonding the knit to these stitches. A wire of thermoplastic material, for example PVC, is preferably used. Thus elements 1 12d and 1 12g of previously formed sole are bonded and the lower part of the footwear element is closed.
Sur la figure 3, les points 217', 218', 219' et 221 ' représentent les positions des points 217, 218, 219 et 221 sur les fontures. L'élément chaussant de la figure 3 peut aussi être réalisé sur une machine à tricoter circulaire. Les mailles de la ligne 217-219 restent alors sur les aiguilles puis sont liées les unes aux autres en utilisant un fil, notamment sur une machine, comme une machine à coudre. En cas de tricotage au niveau du segment 217-219, les dimensions de l'élément chaussant peuvent être obtenues grâce à des constructions tricotées non homogènes. In FIG. 3, the points 217 ', 218', 219 'and 221' represent the positions of the points 217, 218, 219 and 221 on the needle beds. The footwear of Figure 3 can also be performed on a circular knitting machine. The meshes of the line 217-219 then remain on the needles and are then linked to each other using a thread, especially on a machine, such as a sewing machine. In case of knitting at the segment 217-219, the dimensions of the footwear can be obtained through non-homogeneous knitted constructions.
Un deuxième mode d'exécution du procédé selon l'invention permettant de réaliser un élément chaussant selon l'invention est décrit ci-après en référence à la figure 4. Sur cette figure, on représente par exemple la partie droite de l'élément chaussant. Dans une première étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 301 et 302 à un segment s'étendant entre les points 303 et 304. Ceci permet de former un élément 1 1 1 d de languette. On tricote cet élément sur une première fonture. Toutefois, on tricote simultanément, sur une deuxième fonture, un autre élément 1 1 1 g de languette complémentaire permettant de former intégralement la languette 1 1 1 . Pour ce faire, au niveau du segment 301 -304, le ou les fils de tricotage passent d'une fonture à l'autre pour former la languette d'un seul tenant. Pour ce faire des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. La dimension du segment 301 à 304 étant supérieure à la dimension du segment 302-303, on met en œuvre une procédure de tricotage permettant d'obtenir une telle géométrie. Cette procédure est illustrée par les schémas de la figure 6. A second embodiment of the method according to the invention for producing a footwear element according to the invention is described below with reference to FIG. 4. In this figure, for example, the right part of the footwear element is shown. . In a first step, knitting or forming rows of meshes or loops of the segment extending between the points 301 and 302 to a segment extending between the points 303 and 304. This makes it possible to form an element 1 1 1 d of tongue. We knit this element on a first needle bed. However, it is knitting simultaneously, on a second needle bed, another element 1 1 1 g of complementary tongue to integrally form the tongue 1 1 1. To do this, at the segment 301 -304, the knitting yarn (s) pass from one needle bed to another to form the tongue in one piece. To do this means and procedures are in place to allow the son to change the needle. Since the dimension of the segment 301 to 304 is greater than the dimension of the segment 302-303, a knitting procedure is used to obtain such a geometry. This procedure is illustrated by the diagrams in Figure 6.
Dans une deuxième étape, on tricote ou on forme des rangées de mailles ou de boucles de la courbe s'étendant entre les points 305 et 306 à une courbe s'étendant entre les points 307et 31 1 via 310.

Pour ce faire des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. In a second step, we knit or form rows of stitches or loops of the curve extending between the points 305 and 306 to a curve extending between the points 307 and 31 1 via 310. However, we knit simultaneously, on a second needle bed, another element 1 10g of complementary rod for forming the rod 1 10. To do this, at the segment 305-307 or the knitting son pass from one bed to another to form the stem in one piece. To do this means and procedures are in place to allow the son to change the needle.
La liaison suivant le segment 306-303 est réalisée par une procédure de type Intarsia. Dans ces deux premières étapes, les boucles ou mailles sont formées successivement à l'endroit et à l'envers sur chacune des fontures. Ainsi, on forme une zone 1 16 de tricot n'ayant pas tendance à s'enrouler sur lui-même. Pour ce faire, on utilise de préférence le dispositif décrit dans le document de publication de la demande internationale WO2007/025400. The link following the segment 306-303 is carried out by an Intarsia type procedure. In these first two steps, the loops or meshes are formed successively at the place and upside down on each of the needle beds. So, forming a zone 1 16 of knitting not tending to wind on itself. For this purpose, the device described in the publication document of international application WO2007 / 025400 is preferably used.

To do this, means and procedures are put in place to allow the threads to change their needle bed.
Dans une huitième étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 315 et 314 via le point 316 au segment s'étendant entre les points 317 et 319 via le point 318. Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 10g de tige complémentaire permettant de former la tige 1 10. Pour ce faire, au niveau des segments 315-317 et 314-319, le ou les fils de tricotage passent d'une fonture à l'autre pour former la tige d'un seul tenant. Pour ce faire, des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. Dans cette huitième étape, on réutilise des mailles laissées en attente, au niveau du segment 314-316, lors de l'étape précédente et on lie le tricot à ces mailles. Dans une neuvième étape, on tricote ou on forme des rangées de mailles ou de boucles du point 319 au segment s'étendant entre les points 318 et 320. Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 10g de tige complémentaire permettant de former la tige 1 10. Pour ce faire, au niveau du segment 319-320, le ou les fils de tricotage passent d'une fonture à l'autre pour former la tige et la semelle d'un seul tenant. Pour ce faire, des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. Dans cette neuvième étape, on réutilise des mailles laissées en attente, au niveau du segment 319-318, lors de l'étape précédente. In an eighth step, knitting or forming rows of meshes or loops of the segment extending between the points 315 and 314 via the point 316 to the segment extending between the points 317 and 319 via the point 318. However, simultaneously knitting, on a second needle bed, the other element 1 10g of complementary rod for forming the rod 1 10. To do this, at segments 315-317 and 314-319, the knitting yarn or son pass one needle to another to form the stem in one piece. To do this, means and procedures are put in place place to allow the threads to change the needle bed. In this eighth step, we reuse meshes left pending at the segment 314-316, in the previous step and bind the knit at these meshes. In a ninth step, we knit or form rows of stitches or loops from point 319 to the segment extending between points 318 and 320. However, we knit simultaneously, on a second needle bed, the other element 1 10g of complementary rod for forming the rod 1 10. To do this, at the segment 319-320, or knitting son pass from one needle to another to form the rod and sole integrally. To do this, means and procedures are put in place to allow the threads to change their needle bed. In this ninth step, we reuse meshes left waiting at the segment 319-318, in the previous step.
Dans une dixième étape, on tricote ou on forme des rangées de mailles ou de boucles du point 321 au segment s'étendant entre les points 322 et 323. Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 12g de semelle complémentaire permettant de former la semelle 1 12. Dans cette dixième étape, on réutilise des mailles laissées en attente, au niveau du segment 317-318-320, lors des deux étapes précédentes. In a tenth step, we knit or form rows of stitches or loops from point 321 to the segment extending between the points 322 and 323. However, we knit simultaneously, on a second needle bed, the other element 1 12g of complementary sole to form the sole 1 12. In this tenth step, reused meshes left waiting at the segment 317-318-320, in the previous two steps.
Dans une onzième étape, on tricote ou on forme des rangées de mailles ou de boucles du segment s'étendant entre les points 324 et 323 via le point 322 au segment s'étendant entre les points 325 et 326. Toutefois, on tricote simultanément, sur une deuxième fonture, l'autre élément 1 12g de semelle complémentaire permettant de former la semelle 1 12. Pour ce faire, au niveau du segment 323-326 et au niveau de la courbe 324-325, le ou les fils de tricotage passent d'une fonture à l'autre pour former la semelle d'un seul tenant. Pour ce faire, des moyens et des procédures sont mis en place pour permettre aux fils de changer de fonture. Dans cette onzième étape, on réutilise des mailles laissées en attente, au niveau du segment 317-320, lors de la neuvième étape. Alors que les aiguilles des deux fontures sont de préférence utilisées dans leurs positions illustrées à la figure 7 dans les première à onzième étapes, dans une douzième étape, on positionne des aiguilles des première et deuxième fontures dans une position relevée illustrée à la figure 8. Ainsi, on tricote ou on forme des mailles ou de boucles selon le segment 325-323 en réutilisant des mailles laissées en attente dans l'étape précédente. On effectue aussi une connexion tricotée avec les mailles du segment 323-326 On utilise de préférence un fil en matériau thermoplastique, comme par exemple du PVC. On lie ainsi des éléments 1 12d et 1 12g de semelle formés précédemment et on ferme la partie inférieure de l'élément chaussant. In an eleventh step, knitting or forming rows of stitches or loops of the segment extending between the points 324 and 323 via point 322 to the segment extending between the stitches 325 and 326. However, knitting is simultaneously performed. on a second needle bed, the other element 1 12g of complementary sole to form the sole 1 12. To do this, at the segment 323-326 and at the curve 324-325, or knitting son pass from one needle to another to form the sole in one piece. To do this, means and procedures are set up to allow the threads to change their needle bed. In this eleventh step, we reuse meshes left waiting at the segment 317-320, in the ninth step. While the needles of the two needle beds are preferably used in their positions illustrated in Figure 7 in the first to eleventh steps, in a twelfth step, needles of the first and second needle beds are positioned in a raised position illustrated in Figure 8. Thus, we knit or form stitches or loops according to the 325-323 segment by reusing stitches left in the previous step. A knitted connection is also made with the stitches of segment 323-326. A yarn made of thermoplastic material, for example PVC, is preferably used. Thus elements 1 12d and 1 12g of previously formed sole are bonded and the lower part of the footwear element is closed.
Les première à quatorzième étapes du premier mode d'exécution et les premières à onzième étapes du deuxième mode d'exécution sont de préférence mises en œuvre en utilisant du fil en matériau comme par exemple du fil en coton naturel, du fil synthétique, du fil synthétique avec un additif anti-bactérien et/ou améliorant la sensation de confort. The first to fourteenth steps of the first embodiment and the first to eleventh steps of the second embodiment are preferably implemented using material wire such as natural cotton yarn, synthetic thread, yarn. synthetic with an anti-bacterial additive and / or improving the feeling of comfort.
Avantageusement, on comprend qu'on tricote les parties droite et gauche de l'élément chaussant de manière non géométriquement symétrique de sorte à tenir compte des dissymétries des pieds des porteurs. Ces asymétries sont par exemples générées en utilisant des constructions tricotées telles que celles représentées aux figures 5 et 6. Advantageously, it is understood that knits the right and left parts of the footwear in a non-geometrically symmetrical manner so as to take into account the asymmetries of the feet of the carriers. These asymmetries are for example generated using knitted constructions such as those shown in FIGS. 5 and 6.
Le procédé de tricotage permet avantageusement de réaliser des motifs et décors sur l'élément chaussant, notamment par utilisation de fils de couleurs différentes, ou plus généralement d'aspects différents. L'utilisation de plusieurs fils tricotés successivement ou simultanément permet aussi d'obtenir différentes caractéristiques sur l'élément chaussant. Une fois l'élément chaussant réalisé, pour réaliser une chaussure, on peut rapporter une semelle 102 sous l'élément chaussant, par exemple la rapporter par couture et/ou collage. On peut aussi rapporter des passants pour lacet et un lacet 103. Les passants peuvent aussi être formés par tricotage, notamment par tricotage de la tige. The knitting process advantageously makes it possible to produce patterns and decorations on the footwear element, in particular by using threads of different colors, or more generally of different aspects. The use of several knitted yarns successively or simultaneously also makes it possible to obtain different characteristics on the footwear element. Once the footwear element made, to achieve a shoe, can be reported a sole 102 under the footwear, for example report by sewing and / or gluing. One can also report lace loops and a lace 103. The loops can also be formed by knitting, including knitting the rod.
Pour réaliser la chaussure, on peut aussi rapporter un film plastique sur l'élément chaussant tricoté. To make the shoe, we can also bring a plastic film on the knitted footwear.
Le procédé de tricotage selon l'invention peut être mis en œuvre en utilisant un dispositif pour tricoter sélectivement des mailles à l'envers et à l'endroit à l'aide d'aiguilles d'une même fonture 3 comportant une pluralité de rainures de guidage parallèles 4 dans lesquelles les aiguilles 1 , 2 sont montées coulissantes, chacune de ces rainures de guidage 4 recevant une double aiguille composite 1 , 2 comportant deux crochets 5, 6 ouverts latéralement, ménagés respectivement à travers les premières extrémités de deux tiges plates, dont l'une, interne 1 a-1 c, est adjacente au fond de la rainure de guidage 4 et dont l'autre, externe 2a-2c, est coplanaire et adjacente à la tige interne 1 a-1 c. Le dispositif comprend des moyens 10, 1 1 de mise de la seconde extrémité de chacune desdites tiges 1 a-1 c, 2a-2c sélectivement en prise avec deux moyens de commande de tricotage 12-15 d'une maille à l'endroit, respectivement d'une maille à l'envers, la tranche terminale de la première extrémité de la tige externe 2a-2c formant une rampe de glissement de maille 7 à angle aigu avec sa tranche adjacente à l'aiguille interne 1 . Chaque double aiguille 1 , 2 est associée à deux jacks adjacents 18, 19, l'un 18 pour former une boucle, alternativement pour retenir une maille et l'autre 19 pour dégager ladite boucle, chacun de ces jacks étant associé à des moyens 24, 27 de mise en prise sélective avec des moyens de commande. Les figures 9 et 10 illustrent une double aiguille composite faisant partie du dispositif pour tricoter sélectivement des mailles à l'endroit et des mailles à l'envers. Cette double aiguille comporte une première aiguille 1 et une seconde aiguille 2. Ces deux aiguilles 1 et 2 sont allongées et ménagées au travers de deux tiges plates montées coplanaires dans une des rainures de guidage parallèles habituelles 4 d'une fonture 3 d'un métier à tricoter comme illustré par la figure 1 1 . La tige de l'aiguille 1 est montée dans le fond de la rainure de guidage 4 et est la tige interne, alors que la tige de la seconde aiguille 2 qui vient coulisser sur la tige de la première aiguille 1 est la tige externe. Dans le cas de la présente invention, les rainures de guidage sont cependant plus profondes qu'habituellement, pour assurer le guidage de la double aiguille. The knitting method according to the invention can be implemented by using a device for selectively knitting stitches upside down and at the location by means of needles of the same needle bed 3 having a plurality of grooves of parallel guiding 4 in which the needles 1, 2 are slidably mounted, each of these guide grooves 4 receiving a double composite needle 1, 2 comprising two hooks 5, 6 open laterally, formed respectively through the first ends of two flat rods, one of which, internal 1a-1c, is adjacent to the bottom of the guide groove 4 and the other, external 2a-2c, is coplanar and adjacent to the inner rod 1a-1c. The device comprises means 10, 1 1 for setting the second end of each of said rods 1a-1c, 2a-2c selectively engaged with two knitting control means 12-15 of a mesh at the location, respectively an upside down mesh, the end wafer of the first end of the outer rod 2a-2c forming an acute angle mesh sliding ramp 7 with its wafer adjacent to the inner needle 1. Each double needle 1, 2 is associated with two adjacent jacks 18, 19, one 18 to form a loop, alternatively to retain one mesh and the other 19 to clear said loop, each of these jacks being associated with means 24, 27 for selectively engaging with control means. Figures 9 and 10 illustrate a composite double needle forming part of the device for selectively knitting stitches in place and stitches in reverse. This double needle comprises a first needle 1 and a second needle 2. These two needles 1 and 2 are elongate and formed through two flat rods coplanar mounted in one of the usual parallel guide grooves 4 of a needle bed 3 of a loom to knit as illustrated in Figure 1 1. The rod of the needle 1 is mounted in the bottom of the guide groove 4 and is the inner rod, while the rod of the second needle 2 which slides on the rod of the first needle 1 is the outer rod. In the case of the present invention, the guide grooves are however deeper than usual for guiding the double needle.
L'extrémité supérieure ou première extrémité de chaque tige d'aiguille 1 , 2 se termine par un crochet 5, respectivement 6. Dans la forme d'exécution représentée, les deux crochets 5, 6 se font face. Lorsqu'ils se trouvent dans les positions relatives illustrées par la figure 9, la base du crochet 5 de la tige interne forme, avec la tranche terminale de la première extrémité de la tige externe 2 une rampe 7 de glissement de la maille. The upper end or first end of each needle rod 1, 2 ends with a hook 5, respectively 6. In the embodiment shown, the two hooks 5, 6 face each other. When in the relative positions illustrated in Figure 9, the base of the hook 5 of the inner rod forms, with the end portion of the first end of the outer rod 2 a ramp 7 slip of the mesh.
La tige d'aiguille 2 présente, sur une de ses faces et à proximité de sa première extrémité, un élément écarteur 9 pour écarter la boucle de fil de la tige de l'aiguille, dans le but que l'on expliquera par la suite. Cet élément écarteur 9 est formé par un fil-ressort fixé à une de ses extrémités et dont l'autre extrémité peut pénétrer dans un perçage qui traverse la tige de l'aiguille 2. Chaque tige d'aiguille 1 , 2 comporte deux parties parallèles 1 a, 1 b, respectivement 2a, 2b, reliées l'une à l'autre par un double coude 1 c, respectivement 2c. Ceci a pour but de ménager une partie supérieure de la fonture suffisamment mince pour réduire l'écartement entre le lit d'aiguilles de cette fonture avec le lit d'aiguilles de la fonture parallèle (non représentée) dans le cas de la formation d'un tricot tubulaire pour obtenir une transition la moins visible possible entre le nappes tricotées sur les deux fontures. The needle rod 2 has, on one of its faces and near its first end, a spacer element 9 to separate the loop of wire from the needle shaft, for the purpose that will be explained later. . This spacer element 9 is formed by a spring wire fixed at one of its ends and whose other end can penetrate into a bore which passes through the rod of the needle 2. Each needle rod 1, 2 comprises two parallel parts 1a, 1b, respectively 2a, 2b, connected to each other by a double elbow 1c, respectively 2c. This is to provide an upper portion of the needle bed sufficiently thin to reduce the gap between the needle bed of this needle bed and the needle bed of the parallel needle bed (not shown) in the case of the formation of a tubular knit to obtain a least visible transition between the knitted plies on the two needle beds.
A leurs secondes extrémités respectives, les tiges 1 , 2 présentent chacune une saillie de basculement 1 d, respectivement 2d, sur chacune desquelles un actionneur 10, respectivement 1 1 est monté oscillant dans le plan de la rainure de guidage 4. Chaque actionneur 10, 1 1 comporte deux bras destinés à venir alternativement en prise chacun avec deux cames de commande 12, 13, respectivement 14, 15 des aiguilles 1 , 2. Ces cames 12-15 sont solidaires d'un chariot 17 associé à des moyens d'entraînement habituels (non représentés) pour se déplacer selon une direction perpendiculaire au plan de coupe des figures 1 1 et 12. Un sélecteur 16, monté coulissant dans la rainure de guidage 4, présente deux rainures en forme de cames 16a, 16b (figure 12), en prise chacune avec une cheville faisant saillie latéralement de chacun des actionneurs 10, 1 1 . Le sélecteur 16 est déplacé entre ses deux positions illustrées par les figures 1 1 et 12 par un mécanisme de sélection (non représenté), mettant ainsi alternativement les bras des actionneurs en prise avec les cames 13 et 15, respectivement 12 et 14, suivant que l'on désire tricoter des mailles à l'endroit ou à l'envers. At their second respective ends, the rods 1, 2 each have a tilting projection 1d, respectively 2d, on each of which an actuator 10, respectively 1 1 is oscillatingly mounted in the plane of the guide groove 4. Each actuator 10, 1 1 comprises two arms intended to come alternately each engaged with two control cams 12, 13, respectively 14, 15 needles 1, 2. These cams 12-15 are integral with a carriage 17 associated with drive means conventional (not shown) to move in a direction perpendicular to the sectional plane of Figures 1 1 and 12. A selector 16, slidably mounted in the guide groove 4, has two cam-shaped grooves 16a, 16b (Figure 12) , each engaged with a peg projecting laterally from each of the actuators 10, 1 1. The selector 16 is moved between its two positions illustrated in FIGS. 11 and 12 by a selection mechanism (not shown), thus alternately putting the arms of the actuators in engagement with the cams 13 and 15, respectively 12 and 14, depending on whether you want to knit stitches up or down.
Le dispositif de tricotage selon l'invention comporte encore une paire de jacks dont l'un 18 est le jack principal et l'autre 19 est le jack auxiliaire formée par deux lames adjacentes. Chaque paire de jack est associée à chaque double aiguille composite 1 , 2. Le jack principal 18 est adjacent à une des deux grandes faces de la double aiguille 1 , 2 et passe à droite de cette dernière lorsqu'on regarde la fonture 3 du côté des aiguilles 1 , 2. Une des deux grandes faces du jack auxiliaire 19 est appliquée contre une des grandes faces du jack principal 18. A son extrémité avant, le jack auxiliaire 19 présente une partie 19c séparée de la face adjacente du jack principal 18 tout en restant parallèle à cette face adjacente. En même temps, la largeur du jack auxiliaire 19 diminue en allant vers son extrémité avant en formant une rampe 19d. A son extrémité avant, le jack auxiliaire 19 revient en contact avec la face adjacente du jack principal 18. Cette partie parallèle 19c est reliée à la lame du jack auxiliaire 19, respectivement à son extrémité avant, par deux parties 19e, inclinées par rapport au plan de la lame. Cette partie 19c du jack auxiliaire forme ainsi un canal destiné à permettre le passage de l'aiguille interne 1 comme on le verra par la suite. The knitting device according to the invention further comprises a pair of jacks, one of which is the main jack and the other 19 is the auxiliary jack formed by two adjacent blades. Each pair of jack is associated with each double composite needle 1, 2. The main jack 18 is adjacent to one of the two large faces of the double needle 1, 2 and passes to the right of the latter when looking at the needle bed 3 on the side of the needles 1, 2. the two large faces of the auxiliary jack 19 is applied against one of the large faces of the main jack 18. At its front end, the auxiliary jack 19 has a portion 19c separate from the adjacent face of the main jack 18 while remaining parallel to this adjacent face . At the same time, the width of the auxiliary jack 19 decreases towards its front end by forming a ramp 19d. At its front end, the auxiliary jack 19 comes into contact with the adjacent face of the main jack 18. This parallel portion 19c is connected to the blade of the auxiliary jack 19, respectively at its front end, by two parts 19, inclined relative to the plane of the blade. This portion 19c of the auxiliary jack thus forms a channel for allowing the passage of the inner needle 1 as will be seen later.
De préférence, pour mettre en œuvre l'invention, on utilise un dispositif de tricotage tel que décrit précédemment sur chacune de deux fontures d'une installation de tricotage. Preferably, to implement the invention, a knitting device as previously described on each of two needle beds of a knitting installation is used.
