ABSTRACT:
A folding device for folding a web material made of plastics or the like to a predetermined length in a Z-shaped manner. In this device, a web material is guided around folded end holding members, which are suitably, linearly movable to and from respective folding end positions of the web material, by means of a feed mechanism for feeding the web material while the feed mechanism reciprocates between both folded end positions, so that the web material can be folded in a Z-shaped manner.
