Abstract
A longitudinal folding device includes formers for longitudinally forming and folding paper webs having different widths. Each former, together with its folding rollers, hopper roller and longitudinal cutting device is supported in a frame such that the former can be displaced in the axial directions of both the folding rollers and the hopper roller.
Claims6
A folding apparatus comprising:
- at least one longitudinal folding device, said at least one longitudinal folding device including a hopper roller having a hopper roller axis of rotation, a pair of folding rollers having folding roller axes of rotation, a folding hopper situated between said hopper roller and said pair of folding rollers and a longitudinal cutting device;
- and
- means supporting said at least one longitudinal folding device, including said hopper roller, said pair of folding rollers, said folding hopper and said longitudinal cutting device for displacement of said at least one longitudinal folding device in a first axial direction of said hopper roller axis of rotation and in a second axial direction of said folding rollers axes of rotation, said first axial direction and said second axial direction being different from each other.
