Abstract

Une tête (1734) d'un dispositif de poinçonnage (173) d'une machine d'emballage comporte un emporte-pièce (1735) et un outil de coupe de chutes (1737) qui sont disposés verticalement sur une base (17341). La pointe de l'outil de coupe de chutes (1737) s'étend vers l'avant dans la direction Y au-delà de la pointe de l'emporte-pièce (1735). De plus, lorsqu'une partie d'un film pour paquet faisant face à l'emporte-pièce est non défectueuse, le dispositif de poinçonnage (173) perce un paquet d'emballage à partir du film pour paquet et coupe la chute suite au mouvement de la tête (1734) d'une position d'attente à une première position. En revanche, lorsque la partie d'un film pour paquet faisant face à l'emporte-pièce (1735) est défectueuse, le dispositif de poinçonnage (173) coupe la chute suite au mouvement de la tête (1734) d'une position d'attente à une seconde position.
