Abstract

The apron (1) has perforations (2) provided with small holes (3). The holes run across slotted opening of a suction shoe, through which suction air is sucked. Fibers are sucked towards the perforations. The apron compresses a fiber assembly by the ambient air flowing through the perforations. An outer surface of the apron is provided with a corrugation (5), which is aligned transverse to the circumferential direction of the apron. An inner surface of the apron lies on a driving roll, when the apron is drawn across a surface (4) of the shoe.

Description

Gegenstand der ErfindungSubject of the invention

Die Erfindung betrifft ein Verdichtungsriemchen für Faserstreckwerke mit unterschiedlichen Eigenschaften auf beiden Seiten nach der Patentanmeldung 10 2006 030 155.2.The The invention relates to a compaction apron for fiber drafting systems with different Properties on both sides after the patent application 10 2006 030 155.2.

Stand der TechnikState of the art

An Verdichtungsriemchen in Verdichtungsstreckwerken, in denen die Faserverbände dadurch verdichtet werden, dass Saugluft durch die Mittig im Riemchen angeordnete Perforation gezogen wird und die Fasern zu dieser Perforation ziehen, werden andere Anforderungen als an Verzugsriemchen gestellt. Die Fasern sollen nicht zurückgehalten werden, um Abzug von Faserpaketen zu verhindern. Vielmehr sollen sie quer zur Laufrichtung leicht beweglich und gegebenenfalls geführt werden.At Verdichtungsriemchen in compression drafting, in which the fiber bundles thereby compacted be that suction through the center arranged in the perforation perforation and pulling the fibers to this perforation will become others Requirements as put on delay straps. The fibers should not restrained to prevent theft of fiber packets. Rather, should they are easily movable transversely to the direction and possibly guided.

Aufgabe der ErfindungObject of the invention

Der Erfindung war demgemäß die Aufgabe gestellt, der Oberfläche eines Verdichtungsriemchens eine Struktur zu geben, die diese Wirkung zu erreichen gestattet. Um dieses das Verdichten erleichternde und unterstützende Führen der Fasern zu erreichen, wird vorgeschlagen, der äußeren Lauffläche eines Verdichtungsriemchens eine Querriffelung zu verleihen, die ein Gleiten der Fasern in Richtung dieser Riffelung in Richtung auf die Perforation zu erlauben.Of the Invention was accordingly the task the surface To give a compaction belt a structure that has this effect allowed to reach. To make this compacting and compacting supportive To lead To reach the fibers, it is suggested that the outer tread of a Verdichtungsriemchens to give a transverse ribbing, the sliding the fibers in the direction of this corrugation in the direction of the perforation to allow.

Die auf der Antriebswalze aufliegende Innenfläche des Verdichtungsriemchens sollte zumindest dann, wenn das Riemchen über die Fläche eines Saugschuhs gezogen wird, glatt sein. Satte Anlage des Verdichtungsriemchens am Saugschuh verhindert auch durch die Riffeln zuströmende Falschluft zur Saugöffnung des Saugschuhs.The on the drive roller resting inner surface of the Verdichtungsriemchens should be at least when the strap is pulled over the surface of a suction shoe will be, smooth. Full installation of the compacting belt on the suction shoe prevents also by the corrugations inflowing false air to the suction port of the Suction shoe.

Beschreibung der ErfindungDescription of the invention

In den Figuren der Zeichnungen ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Sie zeigt die perspektivische Ansicht eines Verdichtungsriemchens.In the figures of the drawings is an embodiment of the invention shown schematically. It shows the perspective view of a Verdichtungsriemchens.

Das Riemchen 1 weist entlang seiner Mittellinie eine Perforation 2 mit kleinen Löchern 3 auf. Diese Löcher laufen über die schlitzförmige Öffnung eines Saugschuhs, durch den hindurch Umgebungsluft angesaugt wird. Dadurch werden die vom Faserverband abstehenden Fasern in Richtung auf die Perforation angesaugt und der Faserverband verdichtet. Die äußere Oberfläche 4 des Verdichtungsriemchens 1 ist mit einer quer zum Umfang des Riemchens gerichtete Riffelung 5 geringer Tiefe versehen. Die Riffeln können geringeren oder größeren Abstand zueinander haben, sie können tiefer oder weniger tief sein.The strappy 1 has a perforation along its midline 2 with small holes 3 on. These holes run over the slit-shaped opening of a suction shoe, through which ambient air is sucked. As a result, the fibers projecting from the fiber structure are sucked in the direction of the perforation and the fiber composite is compacted. The outer surface 4 of the compaction belt 1 is with a transversely directed to the circumference of the strap corrugation 5 provided shallow depth. The corrugations may be closer or farther apart, they may be deeper or less deep.
