ABSTRACT:
A method and an apparatus for folding pliable material, such as documents, which may differ in quality and length and which are conveyed in assembled form or successively in a transport track. The material is provided with a fold by bending the leading edge and a contiguous portion of the material out of the plane of transport, creating a folding area by guide means and forming the folding edge by folding means. The bending out of the plane of transport of the leading edge and the contiguous portion of the material takes place during the conveying of the material, the bringing into a tubular form of the material, the flattening of the tubular form, and the feeding of the material in that flattened form to the folding means. The apparatus comprises a transport track with feeding means and, as viewed in transport direction, folding means arranged downstream thereof, as well as guide means arranged between the feeding and the folding means. The guide means form a composite hollow body having a substantially tubular inner surface and an insertion opening.
