Abstract

The application relates to a method for zigzag folding a material web, the method having the following steps: continuously feeding a material web to be folded into a folding apparatus along a feed direction, alternately gripping the material web in a proximal region of the folding apparatus by means of gripping devices, holding and conveying the material web by means of the gripping devices into a distal region of the folding apparatus, the material web being zigzag folded thereby, and releasing the material web from the gripping devices and depositing the material web in a stack (9) with folds in the distal region, a distance between adjacent gripping devices (4, 5) being equal to a fold length. Furthermore, the application also relates to an apparatus for zigzag folding a material web.
