ABSTRACT:
Apparatus uses a burster method to bow a continuous web of inserts and thereafter separates the forwardmost insert from the continuous web. A pair of feed rollers advances the forwardmost insert along a predetermined path toward a pair of burst rollers. Upon receipt of the forwardmost insert, the burst rollers first operate at a decreased relative speed with respect to the advancing speed of the web, thereby bowing the continuous web of inserts. The burst rollers then operate at an increased relative speed with respect to the feed rollers, thereby separating the forwardmost insert.
