5297 ABSTRACT OF THE DISCLOSURE A method and apparatus for folding multi-sheet paper products, especially for forming a further longitudinal fold at newspapers having a transverse break. During the formation of the fold or shortly before there is produced a bend in the sheets to be folded, whose curvature is opposite to the curvature of the fold to be formed. In this way there are avoided ray-like extending crease folds in the innermost sheets of the folded product. The apparatus for performing the method contemplates providing a folding element having at least one pair of folding edges which extend in the same direction at their effective region and are laterally spaced from one another, so that there is left free an intermediate space into which there can be displaced the innermost sheets of the product to be folded during the folding operation. The folding edges can be formed at the circumference of rotating, preferably coaxial folding disks, which coact with a smooth or profiled counter disk.
