Abstract

Matted fibrew web is produced by feeding a stream of fibres to form a fleece which in turn is fed acrss a desired width to a hopper plant in which the fleece is opened into fibres or bundles, the fibres or bundles being then fed to a hopper in which they are compacted into a cohesive web. Appts. includes a carding device supplying staple fibres to a feeding device in which the fibres are formed into the fleece, which is fed by an endless belt conveyor into the nip of a clamping device where a combing drum removes the fibres and feeds them into the hopper. One wall of hopper is vibrated by eccentric rollers to effect the compaction into the web.

Description

Verfahren und Vorrichtung zur Bildung von Method and apparatus for forming

mehrdimensionalen Vliesen aus Stapelfasern Die Erfindung bezieht sich auf ein Verfahren zur Bildung von mehrdimensionalen Vliesen aus Stapelfasern. Derartige Vliese sind bisher entweder durch Übereinanderlegen von Krempelfloren oder durch Aufsaugen von Einzelfasern oder Faserbüscheln mit Hilfe von Luft auf Siebflächen gebildet worden. Beide Verfahren sind aufwendig und erzeugen Vliese mit schichtförmigem bzw. schuppenförmigem, d.h. zweidimensionalem Aufbau. multidimensional nonwovens made from staple fibers The invention relates focuses on a process for the formation of multi-dimensional nonwovens from staple fibers. Such fleeces have hitherto been made either by superimposing card pile or by sucking up individual fibers or tufts of fibers with the aid of air Sieve surfaces have been formed. Both processes are complex and produce fleeces with a layered or flaky, i.e. two-dimensional structure.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, ein Verfahren der genannten Art so zu gestalten, daß auf einfache Weise Faservliese mit zumindest annähernd dreimimensionaler Faserlage erzeugt werden.In contrast, the invention is based on the object of a method of the type mentioned so that in a simple manner nonwovens with at least approximately three-dimensional fiber layer can be generated.

Das wird erfindungsgemäß dadurch erreicht, daß ein Krempel- oder Kardenflor zu einem Band zusammengefaßt, dieses einer Schachtanlage in einer gewünschten Vliesbreite vorgelegt und zu Einzelfasern oder Kleinfaserbündeln aufgelöst wird und diese in einem Schacht zu einem Vlies verdichtet werden.This is achieved according to the invention in that a carded or carded pile combined into a band, this one shaft system in a desired width of the fleece presented and dissolved into individual fibers or small fiber bundles and these in compacted in a shaft to form a fleece.

Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung des Verfahrens, die dadurch gekennzeichnet ist, daß die Schachtanlage eine Klemmlinie, bestehend aus wenigstens einer Walze und einer Mulde, der ein Mittel zum Zuführen des Bandes vorgeschaltet ist, eine Abschlageinrichtung zum Herauslösen von Fasern aus der Klemmlinie sowie einen nachgeschalteten, Vlies bildenden Schacht enthält.The invention also relates to a device for performing the Process, which is characterized in that the shaft system has a clamping line, consisting of at least one roller and a trough, which has a means for feeding of the tape is connected upstream, a knock-off device for the removal of Fibers from the clamping line as well as a downstream, fleece-forming shaft contains.

Der vliesbildende Schacht ist vorzugsweise ein Rüttelschacht mit wenigstens einer eine Schwingvorrichtung aufweisenden Schachtwand, wobei Mittel zum Steuern des Rüttelweges und der Rüttelfreguenz vorgesehen sind Hierdurch wird eine zusätzliche Beeinflussung der Vlies-Eigenschaften ermöglicht.The web-forming shaft is preferably a vibrating shaft with at least a shaft wall having a vibrating device, wherein means for controlling of the vibration path and the vibration frequency are provided Influencing of the fleece properties is possible.

Die Dicke des Vlieses wird in erster Linie bestimmt von dem Abstand, den die die Schwingvorrichtung aufweisende Wand von der gegenüberliegenden Wand hat, und in zweiter Linie von der Frequenz und der Amplitude der Schwingungen.The thickness of the fleece is primarily determined by the distance, the wall having the oscillating device from the opposite wall and in the second place on the frequency and the amplitude of the oscillations.

Zweckmäßig weist eine Vorrichtung nach der Erfindung eine Regelvorrichtung auf mit einer den Füllzustand des Schachtes ermittelnden Meßeinrichtung sowie mit einer Stelleinrichtung, welche die Drehgeschwindigkeit der Walzen der Klemmlinie in Abhängigkeit von Signalen der Meßeinrichtung beeinflußt.A device according to the invention expediently has a control device on with a measuring device that determines the filling level of the shaft and with an adjusting device which controls the speed of rotation of the rollers of the nipping line influenced as a function of signals from the measuring device.

Die Zeichnung zeigt schematisch als Ausführungsbeispiel des Erfindungsgegenstandes eine Vorrichtung zur Bildung von mehrdimensionalen Vliesen.The drawing shows schematically an exemplary embodiment of the subject matter of the invention a device for the formation of multi-dimensional nonwovens.

Der Rohstoff 1 wird einer Krempel 2 oder einer Karde herkömmlicher Bauart zugeführt. An die Krempel 2 oder Karde schließt sich eine Bandübertragungs-Einrichtung 3 an. In dieser wird auf herkömmliche Weise der Krempel- oder Kardenflor 4, der eingangs eine Breite von 1 bis 3 m hat, auf die gewünschte Vliesbreite von beispielsweise 6 m gebracht.The raw material 1 is a card 2 or a card more conventional Type supplied. A belt transfer device connects to the card 2 or card 3 at. In this is in a conventional manner the card or card web 4, the initially has a width of 1 to 3 m, to the desired web width of, for example 6 m brought.

An die Bandübertragungs-Einrichtung 3 schließt sich eine Vlies bildende Schachtanlage 5 an. Diese enthält ein unteres und ein oberes Transporttuch 6 mit einer an das obere Tuch anschließenden Transportwalze 6'. Mittels dieser Transportanlage wird das von der Bandübertragungs-Einrichtung 3 gelieferte Vlies-Band 7 bis zu einer Abschlag-Klemmlinie hoch gefördert. Diese wird gebildet von einer Mulde 8 und einer Mulden-Walze 9, die u.U. von einer vorgeschalteten Walze unterstützt wird. Hinter der Abschlag-Klemmlinie befindet sich eine schnell umlaufende, benadelte Abschlagwalze 10. Durch diese wird das Vlies in Einzelfasern oder kleine Faserflocken 11 aufgelöst und nach unten in einen Schacht 12 geschleudert. Eine Wand 13 dieses Schachtes ist schwingbar gelagert und wird mit Hilfe von Exzenterscheiben 14 in Verbindung mit Rüskholfedern 15 in Rüttelbewegungen versetzt. Diese teilen sich dem Fasergut mit, so daß es zu einem Vlies 16 verdichtet wird. Dieses wird durch ein den Schacht 12 unten abschließendes Förderband 17 in Verbindung mit einer Umlenkwalze 18 aus der Schachtanlage 5 ausgetragen. Dabei hat es dank der beschriebenen Behandlung eine nahezu dreidimensionale Faserlage.The tape transfer device 3 is followed by a fleece forming Shaft 5 on. This contains a lower and an upper transport sheet 6 with a transport roller 6 'connected to the upper cloth. By means of this transport system the non-woven tape 7 supplied by the tape transfer device 3 is up to one Tee-off terminal line promoted high. This is formed by a trough 8 and one Trough roller 9, which may be supported by an upstream roller. Behind the knockdown clamping line is a fast rotating, needled knockdown roller 10. This breaks up the fleece into individual fibers or small fiber flakes 11 and thrown down into a shaft 12. A wall 13 of this shaft is pivotally mounted and is with the help of eccentric disks 14 in conjunction with Rüskholfedern 15 set in shaking movements. These are communicated to the fiber material, so that it is compressed to form a fleece 16. This is through a shaft 12 Bottom final conveyor belt 17 in connection with a deflection roller 18 from the Shaft 5 discharged. Thanks to the treatment described, it has a almost three-dimensional fiber layer.

Zur Anpassung an den Durchsatz des Vlieses 16 zwischen dem Förderband 17 und der Umlenkwalze 18 muß die Drehgeschwindigkeit der Mulden-Walze 8 bzw. der Mulden-Walzen so beeinflußt werden, daß eine richtig bemessen@ Nachlieferung von fasern gewährleistet ist. Zu diesem Zweck kann z.B. in dem Schacht eine Fotozelle angebracht werden, die den Füllzustand des Schachtes kontrolLiert und auf die Antriebsmittel der FlaLlen-Walze 8 bzw Nulden-Walzen der KLemmlinie wirttt.To adapt to the throughput of the fleece 16 between the conveyor belt 17 and the deflection roller 18 must be the rotational speed of the trough roller 8 and the Trough rollers are influenced in such a way that a correctly dimensioned @ subsequent delivery of fibers is guaranteed. For this purpose, e.g. a photocell can be installed in the shaft which controls the filling level of the shaft and the drive means the flat roller 8 or the zero roller of the clamping line wirttt.
