Abstract (en)

[origin: EP0823391A2] The machine folds over a paper section (14, 15) in the area of a conveyor section (11). A guide slot (30) feeds the material section over the conveyor extend and has a width, which at least over a part of the section is constant, or the slot in cross-section is at least partly curved with a radius which is greater than the slot width. At least one edge of the guide slot evolves from a virtually even shape in the conveyor direction constantly into an increasingly curved form. In particular, the guide slot at the inlet (31) has its greatest curvature radius.
