A device for separating individual items from a continuous perforated sheet includes a longitudinal burster for separating longitudinal lines of weakening on a perforated sheet, and a transverse burster for separating transverse lines of weakening on a perforated sheet. The longitudinal burster operates by employing a pair of rollers linked to a pulley device, with belts, the belts causing edge strips on a perforated sheet to diverge, and separate, from the perforated sheet, along its longitudinal lines of weakening. The transverse burster separates transverse lines of weakening by causing a perforated sheet tensioned against the surface of the transverse burster to begin to separate, the separation being completed as the perforated sheet continues to move across the transverse burster.
