The element for receiving the material when folded by said blade or blades comprises two rollers, which are moved at a speed corresponding to the conveying speed of the material or substantially corresponding to said speed. The two rollers are further arranged to be displaced in a circular arcuate path, and the blade is arranged to adopt a position between the rollers at a position of the rollers during the revolution. Said two rollers are coupled together and form together a circular arcuate path, but with a blade oriented through the axes of rotation of the rollers constantly adopting one and the same horizontal or vertical direction.</p> |
