Description
Die Erfindung betrifft eine Vlieskrempel nach dem Oberbegriff des Anspruchs 1.The invention relates to a nonwoven card according to the preamble of claim 1.
Eine derartige Vlieskrempel ist aus der EP 0 188 177 bekannt. Die Vlieskrempel weist eine Einzugseinrichtung auf, die Fasermaterial auf einen Vorreißer überträgt sowie eine Übertragungseinrichtung, die das Fasermaterial über Walzen mindestens zweifach von dem Vorreißer auf eine Hauptzylinder der Vlieskrempel überträgt. Bei dem bekannten Stand der Technik werden lediglich Übertragwalzen auf zwei Übertragungswegen verwendet.Such a fleece card is known from EP 0 188 177. The nonwoven carding has a collection device which transfers fiber material to a licker-in, and a transfer device which transfers the fiber material via rollers at least twice from the lickerin to a master cylinder of the nonwoven card. In the known state of the art, only transfer rollers are used on two transfer paths.
Aus der US 1478630 A ist eine Wollkarde bekannt, bei der Fasern mit Hilfe einer herkömmlichen Übertragwalze auf den Hauptzylinder übertragen werden. Eine Arbeitswalze kämmt einen Teil der auf die Haupttrommel übertragenen Fasern wieder heraus und führt sie einer erneuten Kardierung und Mischung mit anderen Fasern zu.From US 1478630 A a wool card is known in which fibers are transferred by means of a conventional transfer roller to the master cylinder. A work roll combs out a portion of the fibers transferred to the main drum and feeds them again with carding and blending with other fibers.
