Abstract (en)
[origin: US4696608A] A transport duct for fiber flocks and similar fibrous material communicates via a plurality of openings with a corresponding plurality of feeding chutes leading to flock-processing equipment, such as carding machines. The duct includes at least one, but preferably more than one, duct section at which the duct undergoes an abrupt change of direction by between 70 DEG and 110 DEG , so that the fibrous material which is carried through the interior of the duct by a transport medium is slowed down by contact with the duct and then descends more abundantly than otherwise into the chute that immediately follows such section as considered in the direction of flow of the transport medium. The presence of the section or sections with abrupt direction change also makes it possible for the duct to circumvent any obstructions which may be present between the individual chutes at the location of use of the duct, thus permitting optimum utilization of available floor space.
