Abstract

L'invention concerne un dispositif (11) ainsi qu'un procédé pour la fabrication d'une nappe de fils (1) à plusieurs couches, constituée d'un assemblage de fils de chaîne supérieur (5) et d'un assemblage de fils de chaîne inférieur (3) ainsi que d'un premier (3) et d'un deuxième (4) assemblage de fils de trame. Le dispositif (11) comprend un premier rouleau de dépôt de fils (23) et un deuxième rouleau de dépôt de fils (24) qui forment entre eux une fente de dépôt de fils (28), dans laquelle le premier et le deuxième assemblage de fils de trame (3, 4) de la nappe de fils (1) peuvent être déposés l'un sur l'autre. Le premier rouleau de dépôt de fils (23) et/ou le deuxième rouleau de dépôt de fils (24), et/ou un troisième rouleau (W3), comportent, sur leur surface extérieure, au moins une rainure (23a) servant à recevoir le premier assemblage de fils de trame (3) ou le deuxième assemblage de fils de trame (4). Cette solution permet d'assurer la fidélité à la forme géométrique d'un modèle de base à reproduire dans la nappe de fils (1) déposée.
