Abstract

L'invention concerne un procédé de fabrication d'un tissu (3) au moyen d'un dispositif. Dans une étape de tissage respective, des fils de chaîne (3.2) permettent de former un pas de chaîne dans lequel un fil de trame (3.1) est introduit et le fil de trame (3.1) est poussé au moyen d'un peigne (5) en direction d'un bord du tissu. Un dispositif d'amenée de fil de trame (4) permet d'ajuster de manière variable l'angle d'amenée d'un fil de trame (3.1). Selon l'invention, l'angle du fil de trame (3.1) à introduire est ajusté à une valeur allant de entre 40° à 90° par rapport aux fils de chaîne (3.2) au moyen d'un dispositif de réglage (1). Le dispositif d'amenée de fil de trame (4) est positionné à l'angle prédéfini au moyen d'un entraînement électrique couplé à un réducteur.
