A fiber conveyor for a fiber blending unit includes a blending belt, wherein fiber material dropped onto the blending belt from a bale opener is transportable away by the blending belt. Opposite guide walls are arranged laterally to the blending belt to guide the fiber material on both sides of the blending belt. A rotary distributor is arranged above the blending belt so that the fiber material dropped onto the blending belt is distributable in a transverse direction of the blending belt between the two guide walls by rotational movement of the rotary distributor.
