Abstract
Apparatus is provided for folding continuous web in zigzag fashion into a stack, which apparatus is suitable for forming a stationary stack from lightweight web from below the stack. The apparatus comprises a reciprocating carriage containing guide elements forming a passage for the web to feed through the carriage as it travels. Belts running around the guide elements and anchored at both ends position the web and support the stack without tending to tear or wrinkle the web as it is being folded. A brake prevents reverse web travel.
