Abstract
Method and apparatus for producing individual stacks of zigzag-folded material from a continuously fed length of material containing cross perforations. A target cross perforation is sensed and halted ahead of the stack being formed. By gripping the material downstream of the target point and reversing the direction of travel of the material, separation at the target point is achieved, after which the completed stack is removed automatically. Continuous feed of material even during stack separation and removal is maintained by provision of an intermediate buffer storage which is drawn down as each stack is being formed.
