Abstract: A multiple-end weft-insertion process which is capable of achieving extremely high yarn density which is uniform in plys of structural fabrics is disclosed, making use of conventional machinery and systems. Yarn (104) is transferred from a shuttle (100) to yarn transfer elements (108) spaced a sufficient distance apart to avoid damage to the yarn, and then transferred to yarn holding elements (110). Each successive pass of the shuttle is adjusted by moving the yarn transfer element parallel to the holding elements, so as to overlap each band deposited by the shuttle. The amount of movement necessary to achieve any desired density is calculated according to established parameters.

Abstract: Procédé d'insertion de trame à extrémités multiples, susceptible de produire une densité de fil très élevée, uniforme dans les plis de tissu structurel, faisant intervenir des machines et des systèmes conventionnels. Le fil (104) est transféré depuis une navette (100) à des éléments (108) de transfert de fil espacés à une distance suffisamment écartée pour éviter d'endommager le fil, et ensuite transféré à des éléments (110) de préhension. Chaque passage successif de la navette est ajusté en déplaçant l'élément de transfert du fil parallèle aux éléments de préhension, de manière à chevaucher chaque bande déposée par la navette. Le nombre de mouvements nécessaires pour obtenir toute densité désirée est calculé en fonction de paramètres établis.
