A cutting mechanism for a receipt-printing machine, which has paper dispensed from a paper supply roll, the cutting mechanism having a "v"-shaped, guillotine blade (40). The blade is driven via a blade holder (42) against a stationary blade (72). There is a blade guide (74) which has side mountings (78) for guiding at least one end tab (43) of the guillotine blade into perpendicular contact with the paper web. The guillotine blade is driven through the blade guide by a drive cam (50), which rotatively engages the blade holder. The cam is driven by a motor-driven gear train that has a timing gear (28) for timing the occurrence of web cutting. The guillotine blade retracts from the blade guide under the influence of spring biasing.
L'invention porte sur un mécanisme de coupe pour imprimante de reçus dont le papier provient d'un rouleau. Ledit mécanisme comporte une lame guillotine en V (40) entraînée par son support (42) contre un support stationnaire (72). Un guide lame (74), muni de montants latéraux (78) guide au moins l'une des pattes d'extrémité (43) de la lame guillotine pour la maintenir en contact perpendiculaire avec la bande de papier. La lame guillotine est entraînée dans le guide par une came d'entraînement (50) qui entre en contact rotatif avec le porte-lame (42). La came est entraînée par un train d'engrenages motorisé doté d'un pignon de distribution (28) fixant la périodicité des coupes. La lame guillotine se retire du guide lame sous l'effet d'un ressort de rappel.
