Abstract

L'invention concerne un procédé et un dispositif permettant de réaliser des configurations tridimensionnelles structurées écartées les unes des autres, notamment des filets écartés les uns des autres. Pour mettre au point un procédé et un dispositif permettant de réaliser des configurations tridimensionnelles structurées de ce type, présentant des écarts particulièrement importants et variables, et de réaliser des formes et des structures adaptées à leur usage final, deux surfaces partielles parallèles du filet sont réalisées à partir de groupes de fils de côté de filet (5) situés dans le sens de travail et de fils de travail superficiels qui les lient transversalement au sens de travail. Au moins un fil de travail d'espacement (14) est lié à un groupe de fils de côté du filet (5) d'une surface partielle du filet. Le fil de travail d'espacement (14) est ressorti du plan de cette surface partielle du filet et est cueilli pour former une boucle afin de former une réserve de fil de travail d'espacement et est lié à au moins un groupe de fils de côté du filet de l'autre surface partielle du filet.
