Dans chaque plan, les fils de chaîne sont placés sans se chevaucher mutuellement. Les deux plans forment un soutien pour les fils de trame et donc pour le tapis.In a preferred embodiment, the warp yarns are placed in at least two planes parallel to each other. In each plane, the warp threads are placed without overlapping each other. The two planes form a support for the weft threads and therefore for the carpet.
Dans une forme de réalisation préférée, les fils de trame sont introduits et tissés sur les fils de chaîne alors qu'ils se trouvent au-dessus ou en dessous des fils de chaîne d'un premier nombre de fils de chaîne juxtaposés et qu'ils se trouvent ensuite en dessous ou au-dessus d'un deuxième nombre de fils de chaîne juxtaposés, qui sont placés directement à côté du premier nombre de fils de chaîne juxtaposés. Dans certaines formes de réalisation, les fils de trame se trouvent ensuite au-dessus ou en dessous des fils de chaîne d'un troisième nombre de fils de chaîne juxtaposés qui se trouvent directement à côté du deuxième nombre de fils de chaîne juxtaposés, et ainsi de suite. Le passage répété de fils de trame en dessous et au-dessus des fils de chaîne alors que le premier nombre, le deuxième nombre et les nombres suivants de fils de chaîne sont gardés constants, forme une rangée d'un motif d'insertion. Un motif d'insertion suivant la présente invention comprend plusieurs de ces rangées. Dans certaines formes de réalisation, un motif d'insertion comprend uniquement des rangées identiques. Dans d'autres formes de réalisation, un motif d'insertion comprend des rangées différentes. Dans chaque rangée du motif d'insertion, lesdits premier, deuxième nombres et les nombres suivants de fils de chaîne sont égaux ou différents entre eux. Le premier nombre, le deuxième nombre ou le nombre de chacun des nombres suivants de fils de chaîne peut être de 1, 2, 3, 4, 5, 6, 7, 8, 9 ou 10 fils.In a preferred embodiment, the weft yarns are introduced and woven on the warp yarns while they are above or below the warp yarns of a first number of juxtaposed warp yarns and they are then below or above a second number of juxtaposed warp yarns, which are placed directly next to the first number of juxtaposed warp yarns. In some embodiments, the weft yarns are then above or below the warp yarns of a third number of juxtaposed warp yarns that lie directly next to the second number of juxtaposed warp yarns, and thus right now. The repeated passage of weft yarns below and above the warp yarns while the first number, the second number and the following numbers of warp yarns are kept constant, forms a row of an insertion pattern. An insertion pattern according to the present invention comprises several of these rows. In some embodiments, an insertion pattern includes only identical rows. In other embodiments, an insertion pattern includes different rows. In each row of the insertion pattern, said first, second, and subsequent numbers of warp threads are equal to or different from each other. The first number, the second number, or the number of each of the following numbers of warp threads can be 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 threads.
Le nombre de fils de chaîne détermine la largeur, la longueur ou le diamètre du tapis. Le premier fil de chaîne occupe la première position en allant de la droite vers la gauche ou de la gauche vers la droite du soutien formé par les fils de chaîne. Les fils de trame sont introduits et tissés sur les fils de chaîne en rangées, de telle manière qu'une rangée commence à hauteur d'un premier fil de chaîne et s'étende jusqu'à un dernier fil de chaîne, à savoir celui qui est situé le plus loin du premier fil de chaîne. L'insertion est effectuée dans une seule direction et/ou dans la direction opposée: de la droite vers la gauche et/ou de la gauche vers la droite le long du soutien formé par les fils de chaîne.The number of warp threads determines the width, length or diameter of the carpet. The first warp thread takes the first position by going from the right to the left or from the left to the right of the support formed by the warp threads. The weft yarns are introduced and woven on the warp yarns in rows, so that a row starts at the height of a first warp yarn and extends to a last warp yarn, namely the one that is located farthest from the first warp. The insertion is performed in one direction and / or in the opposite direction: from right to left and / or from left to right along the support formed by the warp threads.
Le deuxième aspect de l'invention est en outre caractérisé en ce qu'au moins un premier et un deuxième motifs d'insertion sont formés en alternance, la longueur moyenne des fils de trame flottants obtenus suivant le premier motif d'insertion étant plus grande que la longueur moyenne des fils de trame flottants obtenus suivant le deuxième motif d'insertion.The second aspect of the invention is further characterized in that at least first and second insertion patterns are formed alternately, the average length of the floating weft yarns obtained according to the first insertion pattern being greater than than the average length of the floating weft yarns obtained according to the second insertion pattern.
En raison de la différence de longueur moyenne des fils de trame flottants, des sections du tapis qui sont obtenues au moyen du deuxième motif d'insertion sont tissées de façon plus serrée que des sections du tapis qui sont obtenues au moyen du premier motif d'insertion. De ce fait, on fabrique un tapis qui comprend des sections abaissées et surélevées. Ce relief formé de sections abaissées et surélevées est particulièrement stable, étant donné qu'il est obtenu en créant des variations dans les armures solides entre les fils de chaîne et les fils de trame. Cette mesure permettant d'obtenir un relief dans le tapis n'est certainement pas évidente pour un homme du métier connaissant l'état de la technique, étant donné que cet homme du métier s'orienterait plutôt vers l'affinage de méthodes classiques pour la création de relief, comme la mise en place de boucles de hauteur différente.Due to the difference in average length of the floating weft yarns, sections of the carpet that are obtained by means of the second insertion pattern are woven more tightly than sections of the carpet which are obtained by means of the first pattern of insertion. As a result, a carpet is made which includes lowered and raised sections. This relief formed of lowered and raised sections is particularly stable, since it is obtained by creating variations in the solid armor between the warp son and the weft son. This measurement making it possible to obtain a relief in the carpet is certainly not obvious for a person skilled in the art knowing the state of the art, since this person skilled in the art would rather be oriented towards the refinement of conventional methods for creation of relief, like the establishment of loops of different height.
Dans une forme de réalisation préférée, la présente invention procure un procédé suivant le deuxième aspect de l'invention, dans lequel le plus long fil de trame flottant obtenu suivant ledit premier motif d'insertion chevauche au moins deux fils de chaîne juxtaposés de plus que le plus long fil de trame flottant obtenu suivant ledit deuxième motif d'insertion. En d'autres termes, le plus long fil de trame flottant obtenu suivant ledit premier motif d'insertion passe au-dessus d'au moins deux fils de chaîne juxtaposés de plus que le plus long fil de chaîne flottant obtenu suivant ledit deuxième motif d'insertion. De cette façon, dans une forme de réalisation, le plus long fil de trame flottant obtenu suivant ledit premier motif d'insertion chevauche trois fils de chaîne juxtaposés tandis que le plus long fil de trame flottant obtenu suivant ledit deuxième motif d'insertion ne chevauche qu'un seul fil de chaîne.In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein the longest floating weft yarn obtained according to said first insertion pattern overlaps at least two warp yarns juxtaposed by more than the longest floating weft yarn obtained according to said second insertion pattern. In other words, the longest floating weft yarn obtained according to said first insertion pattern passes over at least two more juxtaposed warp yarns than the longest floating warp yarn obtained according to said second yarn pattern. 'insertion. In this way, in one embodiment, the longest floating weft yarn obtained according to said first insertion pattern overlaps three juxtaposed warp yarns while the longest floating weft yarn obtained according to said second insertion pattern does not overlap. only one warp.
Dans une forme de réalisation préférée, le plus long fil de trame flottant obtenu suivant ledit premier motif d'insertion chevauche au moins trois fils de chaîne juxtaposés de plus que le plus long fil de trame obtenu suivant ledit deuxième motif d'insertion. De cette façon, dans une forme de réalisation, le plus long fil de trame flottant obtenu suivant le premier motif d'insertion chevauche quatre fils de chaîne juxtaposés tandis que le plus long fil de trame flottant obtenu suivant le deuxième motif d'insertion ne chevauche qu'un seul fil de chaîne.In a preferred embodiment, the longest floating weft yarn obtained according to said first insertion pattern overlaps at least three more juxtaposed warp yarns than the longest weft yarn obtained following said second insertion pattern. In this way, in one embodiment, the longest floating weft yarn obtained according to the first insertion pattern overlaps four juxtaposed warp yarns while the longest floating weft yarn obtained according to the second insertion pattern does not overlap. only one warp.
Dans une forme de réalisation préférée, la présente invention procure un procédé suivant le deuxième aspect de l'invention, dans lequel lesdits motifs d'insertion sont formés en alternance suivant la direction de la chaîne et/ou suivant la direction de la trame. De cette manière, il est possible de fabriquer un tapis avec plusieurs desdites zones ou sections abaissées et surélevées. Dans certaines formes de réalisation, un même motif d'insertion est ainsi répété plusieurs fois à la suite suivant la direction de la chaîne et/ou suivant la direction de la trame. De cette façon, les dimensions desdites sections abaissées et surélevées dans le tapis peuvent varier. Dans une forme de réalisation spécifique, le premier motif d'insertion est ainsi répété deux fois à la suite dans la direction de la chaîne, à la suite desquels on réalise à son tour dans la direction de la chaîne des armures entre des fils de trame et des fils de chaîne suivant le deuxième motif d'insertion.In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein said insertion patterns are formed alternately in the direction of the warp and / or in the direction of the warp. In this way, it is possible to manufacture a carpet with a plurality of said lowered or elevated areas or sections. In some embodiments, the same insertion pattern is thus repeated several times following the direction of the warp and / or the direction of the warp. In this way, the dimensions of said lowered and elevated sections in the carpet may vary. In a specific embodiment, the first insertion pattern is thus repeated twice in succession in the direction of the warp, after which armor between weft threads is then made in the direction of the warp. and warp threads according to the second insertion pattern.
