Abstract
In a blending device (1) for textile fibers, e.g. fiber flocks of cotton, comprising a fiber collecting device into which disintegrated fiber flocks drop after blending. A horizontal suction channel (10) is arranged at a lower end of the collecting device in which an airflow is created which transports the fiber flocks. The suction channel (10) has a waste collecting chamber (21) arranged in the entrance opposite the fiber collecting device. The waste collecting chamber is separated from the suction channel (10) by a grate (16) arranged in a plane of the surface of the suction channel, and the airflow in the entrance of the fiber collecting device sorts the fiber flocks in a transverse flow which transports the textile fibers down the suction channel while allowing the heavier trash and impurities to fall through the grate (FIG. 2).
