  • Laboratory apparatus for a wet treatment of textile materials
    Patent number: 4899558
    Abstract: A specimen carrier is located in a clearly defined flow path of a treatment liquid in a treatment chamber. This treatment chamber is integrated with a conveying unit to one structural unit. For a realistic representation of the treatment operation the conveying unit comprises a pump having a rotating conveyor part for generating a non-pulsating flow. This flow can thereby be reversed by a reversal of the sense of rotation of the conveying part.
