Summary:Double rotor shear, comprising a first rotor (1) comprising at least one first cutting edge (3a), a second rotor (2) comprising at least one second cutting edge (3b), a driving mechanism (10, 12) for rotatably driving the first rotor (1), wherein said first and second rotors (1, 2) are arranged on axes for moving the cutting edges into and out of a travelling plane of a sheet between said first and second rotors (1, 2), said at least one first cutting edge of the first rotor (1) and said at least one second cutting edge of second rotor (2) forming at least one pair of cutting edges adapted for cutting a sheet between the cutting edges forming said pair, wherein the second rotor (2) is rotatably driven by said at least one first cutting edge (3a) pushing directly or indirectly against said at least one second cutting edge (3b). L'invention concerne une cisaille à double rotor, comprenant un premier rotor (1) comprenant au moins un premier bord de coupe (3a), un second rotor (2) comprenant au moins un second bord de coupe (3b), un mécanisme d'entraînement (10, 12) pour entraîner de façon rotative le premier rotor (1), lesdits premier et second rotors (1, 2) étant placés sur des axes pour déplacer les bords de coupe à l'intérieur et à l'extérieur d'un plan de déplacement d'une feuille entre lesdits premier et second rotors (1, 2), ledit au moins un premier bord de coupe du premier rotor (1) et ledit au moins un second bord de coupe du second rotor (2) formant au moins une paire de bords de coupe conçus pour couper une feuille entre les bords de coupe formant ladite paire, le second rotor (2) étant entraîné de façon rotative par ledit au moins un premier bord de coupe (3a) poussant directement ou indirectement contre ledit au moins un second bord de coupe (3b).
