Abstract
- une première section (A) pour les déplacements de chaque maille libre, jusqu'à son maillage avec la maille correspondante de la chaíne en cours de formation qui a été maillée en dernier, avec un arbre vertical (12) motorisé, portant un support horizontal (15) de guidage pour un coulisseau (16) d'un groupe porte-pince, coulissant horizontalement entre une position reculée inactive et deux positions avancées, respectivement, de prise d'une maille libre d'une machine de formation des mailles et de positionnement de ladite maille libre dans une position de maillage; avec une pince (35) pour la prise de la maille libre, qui est asservie à un mouvement d'avancement hélicoidal suivant de son axe longitudinal, pour réaliser le maillage avec la dernière maille correspondante de la chaíne en formation;
- une deuxième section (B) pour le blocage de l'avant-dernière maille de la chaíne en formation, avec un arbre creux (42) vertical motorisé, coulissant axialement, et portant une glissière horizontale (43) pour un coulisseau (44) pourvu de deux étaux distincts (45,46) et mobile de manière appropriée pour positionner séparément lesdits étaux (45,46) dans la position de blocage d'une maille correspondante de la chaíne en cours de formation.
