Abstract

Dispositif de filières dans lequel un agent adhésif peut être injecté parfaitement sans augmentation de la taille des filières ni coulures de l’agent. Une filière (2) possède un poinçon de découpage (3) permettant de poinçonner un noyau le long de sa périphérie externe et possède également un poinçon de refoulement (4) disposé dans un trou traversant (31) formé dans le poinçon de découpage (3). Le poinçon de découpage (3) comprime, pour poinçonner et empiler le noyau (7), une partie à empiler (73) du noyau poinçonné (7) contre les parties à empiler (73) de noyaux (7) déjà poinçonnés et empilés. Le poinçon de refoulement (4) possède un corps de poinçon (41) présentant un passage d’agent adhésif (42) pénétrant dans la direction axiale du corps, une bobine (8) disposée de manière coulissante pour faire face à la pointe du corps de poinçon (41) avec un jeu prédéterminé (G1) entre ceux-ci et placée pour que sa pointe fasse saillie d’une quantité prédéterminée de la pointe du poinçon de découpage (3), et un ressort de pressage (9) permettant de sceller la bobine (8) en la comprimant contre l’extrémité avant du trou traversant (31) du poinçon de découpage (3).
