ABSTRACT:
An apparatus for folding a sheet of material, for example a newspaper, through an angle of 180.degree. by conveying the material between a rotatable element provided with one or more blades and an element for receiving the material folded by said blade or blades. The element for receiving the material when folded by said blade or blades comprises two rollers (4, 5), which are moved at a speed corresponding to the conveying speed of the material or substantially corresponding to said speed. The two rollers (4, 5) are further arranged to be displaced in a circular arculate path, and the blade (8) is arranged to adopt a position between the rollers (4, 5) at a position (FIG. 4) of the rollers during the revolution. Said two rollers are coupled together and form together a circular arculate path, but with a blade (6) orientated through the axes of rotation of the rollers (4, 5) constantly adopting one and the same horizontal or vertical direction.
