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.
Abstract (de)
Die vorliegende Erfindung bezieht sich auf einen Transportkanal 11 für Faserflocken zum Zuführen von solchen zu längs dem Kanal 11 angeordneten Füllschächten 12, 13, 14 mittels eines Transportmediums. Der Kanal 11 ermöglicht, die Maschinen im Maschinensaal in praktisch beliebiger Weise anzuorden und somit diesen optimal auszunützen. Gleichzeitig ergibt sich eine gleichmässige Flockenverteilung in den Schächten 12, 13, 14. Dies wird dadurch erreicht, dass bei mindestens einem Füllschacht 12, 13, 14 an einer sich bezüglich der Strömungsrichtung des Transportmediums unmittelbar vor dem Schacht befindlichen Stelle der Kanal 11 eine abrupte Richtungsänderung von zwischen 70° und 110° aufweist.
