Abstract

a. L'invention concerne un dispositif pour le transport dans la foule d'un métier à tisser, à pas marchant en particulier, d'un élément d'introduction de la trame, au moyen d'un champ de forces magnétiques placé en dehors de cette foule. b. L'élément d'introduction de la trame porte au moins deux aimants permanents dont la polarité est inversée sur la rangée, un stator étant placé de façon à s'étendre à l'extérieur des deux côtés de la foule et contenant une série de pôles électromagnétiques contrôlables. c. Ce dispositif permet de régler commodément le transport de l'élément d'introduction de la trame en ménageant la chaîneat. The invention relates to a device for transporting in the shed of a weaving loom, in particular stepping, an element for introducing the weft, by means of a field of magnetic forces placed outside this. crowd. b. The weft feeder carries at least two permanent magnets reversed in polarity on the row, a stator being placed so as to extend outward on both sides of the shed and containing a series of poles electromagnetic controllable. vs. This device makes it possible to conveniently adjust the transport of the weft introduction element while sparing the warp
