Abstract
A zig-zag folding apparatus includes a slitter blade which forms one or more longitudinally extending slits completely through a comparatively wide web of paper thus forming two or more individual, narrower sections of paper. A spreader device, located downstream from the slitter blade, is effective to produce a longitudinally extending gap or space between the individual paper sections where the slits were formed, and these separated paper sections are each transferred to an individual folding mechanism to form individual stacks of zig-zag folded sheets.
