Abstract:
1. A method for mixing fibrous components by means of weighing feeding in a weighing cycle wherein the fibrous material to be dosed is removed from fiber bales and transported by a material feed device into a weighing container preceded by a pre-filling chamber, which weighing container is separated from the pre-filling chamber by a controllable flap, and after the weighing has taken place the material is ejected from the weighing container onto a mixing belt, characterized in that a desired theoretical weight curve is given for each fibrous component to a respective weighing device according to which curve the material feed for filling the weighing container during the weighing cycle is controlled by appropriately varying the transport speed, said theoretical weight curve providing total weight of the transported fibrous material at a given time in the weighing cycle and is determined for each fibrous material component based on a predetermined relationship of feed rate of the transported fibrous material as a function of time over the weighing cycle to achieve a theoretical total weight of fibrous material to be transported into the weighing container during the weighing cycle.
