Abstract: A textile fiber blending apparatus comprises a blending conveyor having an upstream end and a downstream end as viewed in its direction of travel; a waste fiber feeder having a discharge end for discharging waste fiber on the upstream end of the blending conveyor for forming a waste-fiber layer thereon; and a useful-fiber mixer having a plurality of fiber hoppers, each having a top portion, a bottom portion and a discharge opening at the bottom portion. The discharge openings are arranged above the blending conveyor, downstream of the discharge end of the waste fiber feeder and each depositing, in succession, a layer of useful fibers, whereby on the conveyor a fiber layer stack is formed, constituted by a lowermost waste fiber layer deposited by the waste-fiber feeder and a plurality of superposed useful-fiber layers. The apparatus further has a fiber removing device arranged at the downstream end of the blending conveyor for receiving the fiber layer stack therefrom.
