Methods and apparatus for bursting perforated paper stock are provided. A feed mechanism is provided for feeding perforated paper stock in a feed direction along a paper path in a printer. The perforated paper stock has sections separated by perforations. A loop area is provided in the printer for accumulating one of the sections of the perforated paper stock. A burst element is provided for bursting a perforation of the accumulated section. In order to burst the perforation of the accumulated section, the feed direction is reversed to draw the perforation of the accumulated section against the burst element, thereby separating the section from the perforated paper stock. A paper dispensing mechanism is provided for advancing the separated section out of the loop area and dispensing the section from the printer.
L'invention concerne des procédés et un appareil permettant de séparer le papier d'impression perforé. L'appareil décrit comprend un mécanisme d'entraînement servant à faire avancer le papier dans une direction d'avance en suivant la fente d'insertion du papier dans une imprimante. Le papier perforé comprend des sections séparées par des perforations. L'imprimante comprend une zone en boucle permettant l'accumulation d'une des section de papier perforé, et un élément séparateur servant à rompre les perforations de la section de papier perforé accumulée. Pour rompre les perforations de la section accumulée, la direction d'avance est inversée, ce qui a pour effet de tirer la perforation de la section accumulée contre l'élément séparateur et de séparer ainsi la section en question de du papier perforé restant. Un mécanisme de distribution de papier permet de faire sortir la section séparée de la zone en boucle et de la distribuer à l'extérieur de l'imprimante.
