Abstract
A fiber guide channel device for an open-end spinning mechanism with a fiber guide channel body, for fixation in an opening roller housing and having a receiving opening for a fiber guide channel insert in the region of a fiber guide channel entry defining a central fiber guide channel for pneumatically transporting individual fibers combed by an opening roller from a feed sliver to a high speed spinning rotor in a negative pressure rotor housing. The fiber guide channel body (14) is configured of a plastics material and the fiber guide channel insert (27) is manufactured as a sleeve-like annularly-closed component of a highly abrasion-resistant material.
