CA 2218494

A power weaving loom has a shed (6) made of warp threads (6) in which a reed (14) is guided back and forth. Weft thread insertion means (26), for example shaped as an insertion band (28) guided on guiding elements (24) linked to a reed lever (23) of the reed (14), are used to insert the weft thread. The guiding elements (24) are coplanar to the mid-plane of a corresponding reed tooth (18a), said mid-plane extending in the direction of motion of a reed tooth (18a). A deflecting member (36) that extends on both sides of the mid-plane in the direction of the weft thread for reliably guiding a warp thread past the guiding element (24) and avoiding interlocking is arranged between the reed tooth (36) and the guiding element (24). Parallel yarns may thus be used in such a power weaving loom even in a high performance range.

Ce métier à tisser comprend un pas de chaîne (4) formé de fils de chaîne (6) dans lequel est guidé un peigne (14) oscillant. Des éléments d'insertion (26) du fil de trame, par exemple sous forme d'une bande d'insertion (28) guidée sur des éléments de guidage (24) reliés à un levier (23) du peigne, servent à insérer le fil de trame. Les éléments de guidage (24) se situent sur le même plan que le plan médian dans le sens de déplacement d'une dent (18a) correspondante du peigne. Un organe déflecteur (36) qui s'étend des deux côtés du plan médian dans la direction du fil de trame est monté entre la dent (18a) du peigne et l'élément de guidage (24) afin de guider de manière sûre le fil de chaîne le long de l'élément de guidage (24) et éviter des accrochages. On peut ainsi utiliser des fils parallèles dans un tel métier à tisser même dans une plage de hautes performances.
