The header including at the front side two circular rotatable knives, a feeding drum being mounted above each knife, said drums being rotatable about the same rotation axis as the respective knives. 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. The central protrusion is an inclined surface bent rearwardly away from the rotatable knives.
