Abstract

L'invention concerne un procédé et un dispositif permettant de couper/maintenir la chaîne dans un métier à mailles cueillies, permettant de couper la chaîne de manière adéquate également dans un tissu comprenant une chaîne dévidée par un mécanisme d'insertion de chaîne, et de maintenir de manière appropriée l'extrémité du fil après la coupe. Dans un métier (1) à mailles cueillies permettant l'insertion d'une chaîne (4), une partie (14) à couper formant une intersection avec la chaîne (4) est créée pendant le mouvement d'aller-retour, à une certaine distance longitudinale de la fonture (6), par un mouvement d'oscillation perpendiculaire à la direction longitudinale de la fonture (6), et mouvement de jeté parallèle à la direction longitudinale, effectués par le mécanisme (2) d'insertion de chaîne. La chaîne (4) dans laquelle est formée la partie (14) à couper est accrochée sur une ou plusieurs aiguilles (7b) de tricot et maintenue en place. La chaîne (4) est ensuite coupée par actionnement d'une lame (15) se déplaçant dans une direction longitudinale par rapport à la fonture (6) pour venir agir sur la partie (14) à couper ainsi maintenue. La chaîne (4) se trouvant du côté du mécanisme (2) d'insertion de chaîne par rapport au point de sectionnement de la partie (14) à couper, est accrochée sur l'aiguille (7b) de tricot et maintenue en place. Le tricot peut alors démarrer avec la chaîne (4) dont l'extrémité avant est maintenue.
