Abstract

L'invention porte sur une peigneuse possédant un groupe de pinces (1) pouvant pivoter alternativement qui comprend une plaque à pinces inférieure (12) et une plaque à pinces supérieure (14), montée mobile, et un peigne fixe (11) ainsi qu'un cylindre de peigne (4) monté de façon rotative au-dessous du groupe de pinces (1) à l'intérieur d'un carter (50), le carter (50) étant en communication avec une source de dépression (P) et présentant au moins une ouverture (R2) qui est en communication avec l'espace (R) compris entre le groupe de pinces (1) et une première paire de cylindres (24) qui y fait suite et à laquelle est associée une deuxième paire de cylindres (25), un élément de nettoyage rotatif (34) étant agencé au-dessus des cylindres de pression supérieurs (24b, 25b) des première et deuxième paires de cylindres (24, 25). Pour éviter les influences perturbatrices affectant le processus de soudage qui résulteraient de l'air aspiré sortant du carter (50), selon l'invention, dans la région comprise entre le groupe de pinces (1) et l'élément de nettoyage (34), est disposé un élément de protection (30) qui s'étend sur la longueur de l'élément de nettoyage, le bord longitudinal inférieur (31) de l'élément de protection (30) qui s'étend vers le haut étant disposé à une distance (a) d'entre 0,1 mm et 7 mm de la surface périphérique (u1) du cylindre de pression (24b) de la première paire de cylindres (24).
