Abstract

A flock extraction apparatus includes a pair of ducts which extend along a track for conveying fiber flock and a diverter chamber at one end of the ducts for directing the flock into one or the other of a pair of transport ducts extending from the diverter chamber. Plates are used to block communication between the diverter chamber and the respective transport ducts as well as to sub-divide the diverter chamber for communication with a respective duct extending along the track.
