ABSTRACT:
An apparatus for mixing textile fiber tufts includes a plurality of serially disposed, generally vertically oriented hoppers; a pneumatic conveying system for advancing an air/tuft mixture to the hoppers for charging the hoppers with fiber tufts from the top; an exhaust-air chamber for receiving the conveying air stream from the air/tuft mixture; and a separator positioned between the exhaust-air chamber and the hoppers for allowing air to enter the exhaust-air chamber and for retaining fiber tufts in the hoppers. There are further provided a mixing chamber extending underneath the hoppers; an arrangement situated at the bottom of each hopper for delivering fiber tufts from the hoppers to the mixing chamber; and a transporting device situated in the mixing chamber for mechanically removing blended fiber tufts therefrom. The apparatus also has a septum for separating the exhaust-air chamber from the mixing chamber in an airtight manner; and an air suction arrangement communicating with the mixing chamber for removing air therefrom.
