Description

kurze Fasern aufnehmen und auf ihrer Oberfläche die io gung der leichteren Teilchen und der längeren und längeren, wiederverwendbaren Fasern festhalten, die kürzeren Fasern durch die Luftströmung zunächst beim Ausschleudern der schweren Verunreinigungen abgebremst und dann zur perforierten Trommel hinzwischen Zuführplatte und perforierter Trommel mit gerichtet wird. Von gleich wichtiger Bedeutung für abgeschleudert werden. Um die Trennung von Ver- das gleichmäßige Ansaugen der wiedergewinnbaren unreinigungen und wiederverwendbaren Fasern zu 15 Fasern ist das Merkmal, daß die Trommel über einen verbessern, ist bereits vorgeschlagen worden, etwa in Antrieb dauernd in wechselnden Richtungen hin- und der Mitte zwischen dem Ende der Zuführplatte und hergedreht wird. Das hat zur Folge, daß der Zustand dem die perforierte Trommel umgebenden Gehäuse des Luftstroms während der Betriebszeit praktisch ein im wesentlichen radial angeordnetes Trennstück konstant gehalten wird, so daß ein einmal einvorzusehen, an dem vorbei durch die in der Trommel 20 gestellter optimaler Luftzustand auch dauernd aufwirksame Saugvorrichtung Luft durch eine dicht rechterhalten wird,
unterhalb der Zuführplatte angeordnete Einlaßöffnung angesaugt wird. Bei dieser bekannten Anordnung wird die Luft durch das Trennstück zunächst nach unten abgelenkt und dann um das untere 25
Ende des Trennstücks herumgesaugt, worauf sie nach
oben zum Spalt zwischen Trommelgehäuse und Vorreißerumfang strömt. Zwischen Zuführplatte und
Trennstück werden vom Vorreißerumfang Verunreinigungen sowie längere und kürzere Fasern durch 30
die auf sie einwirkende Fliehkraft abgeschleudert und
durch den vor dem Trennstück nach unten gerichteten Luftstrom noch beschleunigt. Dabei werden
auch die Teilchen, die der perforierten Trommel zugeführt werden sollen, beschleunigt, so daß ein Teil 35
von ihnen die Umkehrbewegung am unteren Ende des
Trennstücks nicht mitmacht und daher verlorengeht.
Ein weiterer Nachteil der bekannten Einrichtung
besteht darin, daß die Menge und GeschwindigkeitTake up short fibers and hold onto their surface the lighter particles and the longer and longer, reusable fibers, the shorter fibers are initially slowed down by the air flow when the heavy impurities are thrown out and then directed towards the perforated drum between the feed plate and perforated drum. Equally important for being thrown off. In order to improve the separation of the uniform suction of the recoverable impurities and reusable fibers to 15 fibers, the feature that the drum has over one has already been proposed, such as in driving continuously in alternating directions back and forth between the end of the Feed plate and is rotated. This has the consequence that the condition of the housing of the air flow surrounding the perforated drum is kept constant during the operating time by means of a substantially radially arranged separating piece, so that an optimal air condition provided in the drum 20 is also permanently provided effective suction device air is retained by a tightly right
inlet opening arranged below the feed plate is sucked in. In this known arrangement, the air is first deflected downwards by the separator and then around the lower 25

Separation piece removes impurities from the lickerin circumference as well as longer and shorter fibers through 30
the centrifugal force acting on them is thrown off and
accelerated by the airflow directed downwards in front of the separator. Be there

Separating piece does not participate and is therefore lost.
Another disadvantage of the known device
is that the amount and speed

Bei der bekannten Unterhalb des Vorreißers 23 ist eine perforierteof the air flow is largely supplied from the surface condition of the 40 lickerins 23 from which the perforated drum, d.
