Abstract

L'invention concerne un groupe pince (1) d'une peigneuse. Ce groupe pince comprend un châssis de pince (8), effectuant un mouvement de va-et-vient et pourvu d'une plaque de pince inférieure (12), une plaque de pince supérieure (14) montée dans le châssis de pince par l'intermédiaire de bras pivotants latéraux (15, 15a), laquelle plaque de pince supérieure peut former un point de serrage avec la plaque de pince inférieure (12) au niveau de la lèvre (13) de plaque de pince, et un cylindre d'alimentation (27) monté au-dessus de la plaque de pince inférieure (12) dans des logements de support (26) du châssis de pince (8). Sur les solutions connues, l'accessibilité pour le démontage du cylindre d'alimentation n'est pas optimale et l'accès n'est possible qu'au moyen d'un outil spécial. Par conséquent, selon la présente invention, les bras pivotants latéraux (15, 15a) de la plaque de pince (14) sont conçus et agencés de façon à se trouver en dehors de la zone (B) traversée par le cylindre d'alimentation (27) lorsque ce dernier est transféré d'une position de fonctionnement à une position d'arrêt de fonctionnement, perpendiculairement à son axe (28).
