Device for zigzag folding of webs of paper or the like

摘要

For the folded stacking of webs (6) produced adjacently in two copies, the web is separated by a longitudinally extending, interrupted separating cut (33) so that webs (32) remain between the individual separating cuts. A transverse perforator (21) is set up such that it applies a transverse perforation, forming the folding edge (34), in the region of the web (32). The pile (12) is formed by a folding arm (36) and is arranged lying obliquely. Situated on the pile on the upper pile edge in the region of the separating cut are holding devices (40) in the form of holding screws (42, 43) which engage in the pile in the region of the folding edges (34). Either the webs (32) or the holding screws (42, 43) or both together can be used as holding devices. They prevent the pile from collapsing while it is being formed. <IMAGE>
