Abstract
A device and process for separating impurities from textile fibers during horizontal pneumatic transport is provided. The device includes a hollow parallelepiped separator of rectangular cross-section for the passage of transport fluids, such as air, therethrough. The passage section is subdivided into an upper part, for the cleaned fluid, and a lower part, for the separation of the impurities (i.e., foreign materials) in a hopper intercepted by an extractor having a seal. This subdivision is regulated by a deflector knife which induces an S-shaped motion of the transport fluid 4 and separates the impurities (i.e., foreign materials) by centrifugal force.
