The device has a fiber guide channel body (14) fixed in an opening roller housing. The body has a receiving opening (15) for a fiber guide channel insert (27) defining a central fiber guide channel (13) for pneumatically transporting individual fibers. The body is made of a plastics material. The insert is made of a highly abrasion-resistant material as a sleeve-like component fully closed in its annular extent. The fibers are combed by an opening roller from a feed sliver to a spinning rotor revolving at a high rotational speed in a negative pressure-loadable rotor housing. |
