The invention relates to a method for producing tissue with the aid of a weaving loom comprising a stop bar, at least one shed and a heddle for carrying out said method. The inventive method is characterised in that a warp thread (I) guiding a filling yarn (1) co-operates with a longitudinal heddle (01) connected to the filling yarn and is arranged between said filling yarn and the stop bar of the weaving loom. The warp thread (I) passes through the filling yarn (1) and a longitudinal heddle (01) controlled by a Jacquard device (10) which carries out normal yarn up-and-down movement (down-and-up). Two superposed wefts which are arranged below and under the shed are simultaneously inserted therein. In order to produce a visible section of the filling yarn above a tissue layer (pattern) during the descending (ascending) movement of the filling yarn (1), the longitudinal heddle (01) is displaced in an ascending (descending) position by the Jacquard device in such a way that the longitudinal heddle (01) provided with a corresponding eye whose lower (top) end is in the centre of the shed (central position) prevents the warp thread (I) guided by the filling yarn (1) from moving downward (upward) beyond the shed centre, and the lower (top) weft is located outside said shed is inserted.

L'invention concerne un procédé de fabrication d'un tissu sur une machine à tisser, comportant une butée et au moins un pas de chaîne, ainsi qu'une lisse plate notamment destinée à cet effet. Ledit procédé est caractérisé en ce que une lisse à lame (1) guidant un fil de trame, fonctionne avec une lisse longitudinale (O1), affectée à la lisse à lame, logée entre la lisse à lame (1) et la butée (12) de la machine à filer. Le fil de trame (I) est enfilé à travers de la lisse à lame (1) et la lisse longitudinale associée (O1), la lisse longitudinale (O1) étant commandée par un dispositif Jacquard (10) effectuant un mouvement de lisse normal haut-bas (bas-haut). Deux trames superposées (au-dessus et en-dessous du centre du pas) sont insérées simultanément dans le pas. Pour créer une section de fil de trame visible au-dessus de la couche de tissu (motif), lors du mouvement descendant (ascendant) de la lisse à lame (1), la lisse longitudinale (O1) est déplacée en position de mouvement ascendant (descendant) par le dispositif Jacquard, de telle manière que la lisse longitudinale (O1) présentant un oeillet correspondant dont l'extrémité inférieure (supérieure) se trouve alors au centre du pas (position centrale), empêche le fil de trame (I) guidé par la lisse à lame (1) de se déplacer vers le bas (haut), au-delà du centre du pas, et la trame inférieure (supérieure) est insérée à l'extérieur dudit pas de chaîne.
