Abstract

L'objectif de l'invention est de créer une machine à tisser, conçue de préférence sur la base du système d'entraînement pour les moyens de formation de la foule selon DE 101 28, permettant de concevoir de manière individuelle le dessin de tissage et l'armure. A cet effet, la première et la deuxième lame (5;9) présentent des lamettes (6;10) qui sont disposées à la manière de lisses dans les lames. De plus, chaque lamette individuelle (6;10) présente un élément (7;11) configuré de sorte qu'au moins un fil de chaîne (2;3) peut, à chaque fois, entrer dans chaque lamette (6;10) et sortir de celle-ci pour former la foule. En outre, chacune des lamettes (6;10) comportant ledit élément (7;11) coopère avec un actionneur (13;14) pouvant être commandé pour modifier la position de l'élément à l'intérieur de la lame.
