Abstract

Selon un procédé de fabrication d'un sac à partir d'un boyau (20) comportant des lignes de perforations transversales délimitant des pattes du futur sac, une patte arrière (232) d'un premier sac (27) étant en regard d'une patte avant (231) du deuxième sac (28) suivant le premier, - on procède dans une première étape à une séparation du premier et du deuxième sac (27, 28) ; - dans une deuxième étape, on sépare un déchet (26) restant sur l'un des sacs (28) entre les deux pattes (231, 232). On réalise la première et la deuxième étape entre d'une part une première paire de cylindres (51) de séparation et d'autre part une deuxième paire de cylindres (52), le déchet (26) étant pincé entre les cylindres de la première paire (51) lors de la première étape pour être retenu sur le deuxième sac (28), puis pincé et arraché par la deuxième paire (52) lors de la deuxième étape, la première paire de cylindres (51) étant animée d'une vitesse périphérique inférieure à celle de la deuxième paire (52) au moins pendant la première et la deuxième étape. Machine mettant en œuvre ledit procédé.
