The header may also be provided with a front feed roll placed behind the knives and two additional feed rolls placed behind the front feed roll, wherein the front feed roll is equipped with guiding blades along the length of the feed roll. The blades have a central protrusion, so that the blades are longer in a region around the middle of the blade than at the lateral ends of the blades.
