Abstract
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.
