<p>A device for channeling a pneumatically conveyed fiber tuft stream includes a housing defining a chamber; a main conduit merging into the chamber for guiding the fiber tuft stream into the chamber; first and second branch conduits extending from the chamber for guiding the fiber tuft stream out of the chamber; first and second air intake openings provided in the housing for allowing air, situated externally of the main conduit, to be drawn into the first and second branch conduits; and a routing gate assembly disposed in the chamber and including first and second routing gates each having a surface cooperating with respective first and second air intake openings. The routing gate assembly has a first operational state for channeling the flow from the main conduit simultaneously into the first and second branch conduits; a second operational state for channeling the flow from the main conduit solely into the first branch conduit; and a third operational state for channeling the flow from the main conduit solely into the second branch conduit. In the second and third operational states one of the first and second routing gates blocks directly one of the first and second air intake openings with the surface of the routing gate.</p> |
