Abstract

Une cisaille volante à tambour de type à découpe par roulement comprend une crémaillère (1) et un tambour de découpe par roulement (2). Le tambour à découpe par roulement (2) est axialement parallèle et comprend un tambour supérieur (21) et un tambour inférieur (23) qui sont disposés en regard en haut et en bas. Les sens de roulement du tambour supérieur (21) et du tambour inférieur (23) sont opposées ; un canal de transport par roulement est formé entre le tambour supérieur et le tambour inférieur au moyen du serrage du tambour supérieur et du tambour inférieur ; une lame de cisaillement supérieure (22) est disposée à demeure sur le côté de circonférence externe du tambour supérieur (21) ; une lame de cisaillement inférieure (24) est disposée à demeure sur le côté de circonférence externe du tambour inférieur (23) ; la lame de cisaillement supérieure (22) est une structure à extension courbe s'étendant obliquement d'une extrémité dans la direction axiale du tambour supérieur (21) à l'autre extrémité le long de la circonférence externe du tambour supérieur (21) ; la lame de cisaillement inférieure (24) est une structure à extension courbe s'étendant obliquement d'une extrémité dans la direction axiale du tambour inférieur (23) à l'autre extrémité le long de la circonférence externe du tambour inférieur (23) ; la lame de cisaillement inférieure (24) et la lame de cisaillement supérieure (22) sont agencées de manière alignée et ont des sens de roulement inclinés opposés, de telle sorte que lorsque le tambour supérieur (21) et le tambour inférieur (23) tournent, la lame de cisaillement inférieure (24) et la lame de cisaillement supérieure (22) puissent venir en prise l'une avec l'autre conjointement avec le roulement du tambour supérieur (21) et du tambour inférieur (23), de façon à cisailler de l'acier en bande introduit entre le tambour supérieur (21) et le tambour inférieur (23).
