Abstract
Method and device for folding pliable material. Arranged approximately on opposite sides of a feeding plane and directly opposite each other are folding rollers. The starting point is a position of the pliable material where a portion of the pliable material is in the feeding plane and a portion is bent out of that plane. An arcuate poriton of the portion of the pliable material that is bent out of the plane is folded over and conducted to a folding/nipping area between the folding rollers by pressing that portion at at least one location against the proximal folding roller and rotating this folding roller. A trailing portion of the pliable material is fed from the feeding plane in a controlled fashion. The folding rollers then make the fold. The invention enables accurate control of the location where the fold is made and the exertion of a relatively small force is sufficient for the pliable material to be conducted into the folding nip. The trailing portion of the pliable material passes through the folding device without being substantially bent.
