Abstract
Es ist eine Vorrichtung bekannt, bei der das auf einem Endlosband zur Wasservernadelung ankommende voluminöse Vlies zwischen einer Vernadelungstrommel und einem weiteren Band langsam verdichtet und gleichzeitig von einem ersten Wasservorhang aus dem Düsenbalken genetzt wird, dessen Wasserstrahlen zunächst das Endlosband und dann die Faserbahn und letztlich die Vernadelungstrommel durchströmen. Eine einfachere und somit preiswerter herstellbare Vorrichtung dieser Art ist gegeben, wenn statt der Vernadelungstrommel diese Kompaktiereinheit nur aus zwei Endlosbändern besteht, die aber so zu führen sind, das am Einlauf die beiden Arbeitstrums der Endlosbänder das einlaufende Vlies langsam kompaktieren, pressen und anschließend die aufeinanderliegenden Bänder gepresst gehalten an dem Düsenbalken vorbeibewegt werden. Dazu dienen zusätzliche Umlenkwalzen. <IMAGE>A device is known in which the voluminous fleece arriving on an endless belt for needling water is slowly compressed between a needling drum and a further belt and at the same time is wetted by a first water curtain from the nozzle bar, the water jets of which are first the endless belt and then the fiber web and finally the Flow through the needling drum. A simpler and thus less expensive to produce device of this type is given if instead of the needling drum, this compacting unit consists of only two endless belts, but which are to be guided in such a way that the two working strands of the endless belts slowly compact the incoming fleece at the inlet, press it, and then the ones lying on top of each other Tapes held pressed are moved past the nozzle bar. Additional deflection rollers serve this purpose. <IMAGE>
Description
Aus der EP-A-0 959 076 ist eine Vorrichtung zum hydrodynamischen Verschlingen zum
vorzugsweise bindemittelfreien Verfestigen der Fasern einer Faserbahn aus natürlichen
und/oder künstlichen Fasern jeglicher Art bekannt. Sie besteht aus
Die Vorrichtung dieser Art hat den Vorteil, dass die voluminös vorlaufende Faserbahn zwischen den beiden Endlosbändern langsam zunehmend und mit gleichmäßigem Druck von oben und unten ohne Scherbeanspruchung verdichtet wird und erst dann, wenn sie zwischen den beiden Endlosbändern fest gehalten ist, an der Vernadelungstrommel genetzt wird. Durch die beiden Walzen vor und hinter dem Düsenbalken wird das Vlies stärker gegen die Vernadelungstrommel gepresst. Diese stärkere Verdichtung oder richtiger, der bessere Halt der Fasern der Faserbahn beim Netzen verhindert ein Verschwimmen von Einzelfasern und führt letztlich zu einem besseren Vliesprodukt.The device of this type has the advantage that the bulky fiber web between the two endless belts slowly increasing and with even Pressure is compressed from above and below without shear stress and only then if it is firmly held between the two endless belts, on the needling drum is wetted. Through the two rollers in front of and behind the nozzle bar the fleece pressed harder against the needling drum. This stronger compression or more correctly, the better hold of the fibers of the fibrous web prevents them from wetting blurring of individual fibers and ultimately leads to a better nonwoven product.
Die Vorrichtung hat sich in der Praxis bewährt, sie zeichnet sich insbesondere durch eine gleich auf der Trommel erzeugte intensive Benetzung und anschließend nach Abführung des zweiten vom ersten Endlosband durch eine auf der Trommel noch mögliche Vernadelung mittels eines zweiten, jetzt unmittelbar gegen die auf der Trommel liegende Faserbahn gerichteten Düsenbalken aus. Die Konstruktion ist aber sehr aufwendig und für manche Produkte zu teuer. Es liegt der Erfindung die Aufgabe zugrunde eine einfachere Konstruktion zu finden, die die gleichen Bedingungen erfüllt.The device has proven itself in practice, it is characterized in particular by an intensive wetting generated immediately on the drum and then after Removal of the second from the first endless belt by one that is still possible on the drum Needling by means of a second, now directly against that on the drum lying fiber web aligned nozzle bar. The construction is very complex and too expensive for some products. It is the object of the invention to find a simpler construction that meets the same conditions.
Zur Lösung der gestellten Aufgabe sieht die Erfindung eine Vorrichtung zum hydrodynamischen
Beaufschlagen einer Faserbahn mit einem Fluid zum vorzugsweise bindemittelfreien
Verfestigen der Fasern der Faserbahn aus natürlichen und/oder künstlichen
Fasern jeglicher Art vor, die besteht aus:
Mit dieser Vorrichtung ist erreicht, dass ähnlich wie bei der Vorrichtung nach der EP-A-0 959 076 das zu netzende Vlies zwischen den Endlosbändern zunehmend gepresst und damit kompaktiert und dann auch weiterhin fest gehalten ist. Es kommt also hier auf ein langsames Kompaktieren und auf das Fixieren, Festhalten des vorzugsweise auch dünnen Vlieses zwischen den Bändern beim Beaufschlagen mit den ersten Wasserstrahlen an. Dies ist gegeben bei der vorbekannten Vorrichtung, wo die Endlosbänder beim Wasservernadeln gegen die Vernadelungstrommel gepresst werden. Bei dieser neuen Vorrichtung entfällt die Vernadelungstrommel und es wird in einfacherer Weise nur zwischen den beiden Arbeitstrums der Endlosbänder vernadelt. Diese können aber dem Druck der Wasserstrahlen nachgeben. Auch um dieses Problem zu beseitigen, müssen die Endlosbänder im Bereich des Düsenbalkens exakt geführt gehalten sein. Dies ist mit nur einer oder besser zwei zusätzlichen Umlenkwalzen erzielbar.With this device it is achieved that similar to the device according to EP-A-0 959 076 the fleece to be wetted is increasingly pressed between the endless belts and thus compacted and then still held firmly. So it comes here on a slow compacting and on fixing, holding the preferably also thin fleece between the tapes when applying the first water jets on. This is the case with the previously known device, where the endless belts are pressed against the needling drum when needling water. At this The new device eliminates the needling drum and it becomes simpler Needled only between the two working strands of the endless belts. these can but give in to the pressure of the water jets. Also to get rid of this problem the endless belts must be guided exactly in the area of the nozzle bar be kept. This can be achieved with only one or better two additional deflection rollers.
Das Ziel bei der erfindungsgemäßen Vorrichtungsergänzung ist erreicht, wenn diese zusätzliche Umlenkwalze für beide Endlosbänder derart in die Ebene der vorlaufenden Trums verlagert ist, dass an dieser je nach dem gewünschten Pressdruck ein für die Endlosbänder größerer oder kleinerer Umschlingungswinkel entsteht. Er muss also größer als 1 Grad sein und liegt in der Praxis wohl zwischen 5 und 35, bis zu 45 Grad.The aim of the device supplement according to the invention is achieved if this additional guide roller for both endless belts in the plane of the leading Trums is relocated to that depending on the desired pressure Endless belts with a larger or smaller wrap angle are created. So he has to be greater than 1 degree and in practice is probably between 5 and 35, up to 45 degrees.
Mehrere Vorrichtungen der erfindungsgemäßen Art sind in der Zeichnung beispielhaft dargestellt. Anhand dieser sollen noch weitere erfinderische Details erläutert werden. Es zeigen:
- Fig. 1
- in der Seitenansicht eine Kompaktiereinheit mit zwei zur Anpressung der Endlosbänder gleichsinnig nach oben versetzten Umlenkwalzen,
- Fig. 2
- die Vorrichtung nach Fig. 1 mit weiterhin zwei gegensinnig bewegten Umlenkwalzen, um die sich die Bänder mäanderförmig schlingen,
- Fig. 3
- eine Vorrichtung ähnlich der nach Fig. 2, jedoch mit einem Düsenbalken, der zwischen den mäanderförmig umschlungenen Umlenkwalzen angeordnet ist, und
- Fig. 4
- ein nur teilweise anderer Aufbau gegenüber der Vorrichtung nach Fig. 2.
- Fig. 1
- in the side view a compacting unit with two deflecting rollers which are displaced upwards in the same direction for pressing on the endless belts,
- Fig. 2
- 1 with two deflecting rollers moving in opposite directions, around which the bands wind in a meandering fashion,
- Fig. 3
- a device similar to that of FIG. 2, but with a nozzle bar, which is arranged between the meandering looped deflection rollers, and
- Fig. 4
- an only partially different construction compared to the device according to FIG. 2.
In einem nicht dargestellten Rahmengestell ist eine Kompaktiereinheit 1 mit nur einem
Düsenbalken 2 mit Absaugung 2' dargestellt. Diese Einheit 1 ist normalerweise die
erste Einheit einer größeren Wasservernadelungsanlage, bei der sich also mehrere
weitere z. B. Band-Vernadelungseinheiten anschließen können.In a frame frame, not shown, there is a compacting
Grundsätzlich besteht diese Einheit 1 aus einem ersten Endlosband 3, das über mehrere
in einem nicht dargestellten weiteren Haltegestell drehbar angeordnete Walzen 4,
5, 6 umgelenkt und gespannt gehalten ist. Auf dieses Endlosband läuft in Richtung des
Pfeils 7 eine zu vernadelnde zunächst voluminösere Faserbahn 8. Es kann auch eine
Faserbahn sein, die sehr dünn ist und insofern mit zunächst keiner Festigkeit versehen
ist und somit von einer nicht dargestellten Krempel direkt auf das Endlosband 3 abgelegt
wird.Basically, this
Dem ersten Endlosband 3 ist ein zweites Endlosband 9 gegenläufig derart zugeordnet,
dass das Arbeitstrum 3' des ersten Endlosbandes 3 dem Arbeitstrum 9' des zweiten
Endlosbandes gegenüberliegt, dort die Trums 3', 9' in der gleichen Richtung umlaufen
und in diesem Bereich konisch aufeinander zu laufen. Dies ist wiederum durch mehrere
Walzen 10 - 12 des Endlosbandes 9 bewirkt, die am genannten Rahmengestell
drehbar gelagert sind.The first
Zwei der Walzen des ersten Endlosbandes 3, nämlich die Walzen 4 und 5 spannen
das Endlosband 3 gegen das Endlosband 9, dessen Arbeitstrum 9' zwischen den Walzen
10, 11 gespannt gehalten ist. Dies heißt, dass die Walzen 4 und 5 das gespannt
geführte Endlosband 3' gegen das Endlosband 9' von unten drücken. Damit tangieren
die Endlosbänder 3', 9' die Umlenkwalzen 4, 5 nicht, sondern sie sind mit einem Anpresswinkel
α umschlungen. Sie sind dicht beieinander angeordnet und lassen zwischen
sich soviel Platz, dass der Düsenbalken 2 mit der Absaugung 2' genügend Platz
hat. Auf diese Weise ist die gelieferte und von dem Trum 3' des Endlosbandes 3 vorgetragene
Faserbahn nicht nur zwischen den Endlosbänder 3 und 9 langsam verdichtet,
sondern beim Netzen gepresst gehalten. Außerdem sind die Endlosbänder im Bereich
der Absaugung 2' nach unten abgestützt, so dass die Bänder 3', 9' nicht dem
Druck der Wasserstrahlen nachgeben können.Two of the rollers of the first
Das gleiche Prinzip ist beibehalten, wenn wie im Ausführungsbeispiel nach Fig. 2 dargestellt
zwei zusätzliche Walzen 13, 14 ober- und unterhalb der Endlosbänder 3', 9'
vor dem Düsenbalken 2 vorgesehen sind und diese die beiden Endlosbänder 3', 9'
zwischen sich halten und dann derart gegeneinander verlagert sind, dass die beiden
Walzen 13, 14 von den Endlosbänder 3', 9' mit dem Anpresswinkel α mäanderförmig
umschlungen sind. Die Walze 4 kann das Endlosband 3' unmittelbar vor dem Düsenbalken
2, 2' unten abstützen. Bei diesem Ausführungsbeispiel wird ein höherer Anpressdruck
gegen das Vlies entstehen.The same principle is maintained if as shown in the embodiment of FIG. 2
two
Bei der Vorrichtung nach der Fig. 3 sind die Umlenkwalzen 13, 14 etwas voneinander
weg im Haltegestell angeordnet, jetzt Walzen 14, 11, und die Düseneinheit 2", 2'" zwischen
diesen Umlenkwalzen 14, 11 angeordnet. Eine weitere Umlenkwalze 15 kann
der Walze 14 oberhalb der Bänder 3', 9' zur weiteren Anpressung des einlaufenden
Vlieses vorgesehen sein. Dies gilt auch für die Fig. 1, wo diese Walze 15 ebenfalls
fakultativ dargestellt ist.3, the
In der Fig. 4 ist auf die Bänder-Unterstützungswalze 5 verzichtet, so dass die Vorrichtung etwas kompakter gebaut werden kann.In Fig. 4, the belt support roller 5 is dispensed with, so that the device can be built a bit more compact.
In allen Ausführungsbeispielen ist der Kompaktiereinheit 1 ein weiterer Düsenbalken
16 mit Absaugung 16' zugeordnet, der für das frei auf dem ersten Endlosband 3' liegende
genetzte Vlies zur unmittelbaren Vernadelung vorgesehen ist. Vorher ist also
das obere zweite Endlosband 9 nach oben abgelenkt, so dass das Vlies oben nicht
weiter abgedeckt ist. Der Düsenbalken 16 sollte auf jeden Fall noch dem ersten Endlosband
3 zugeordnet sein, damit das Vlies vor der Abnahme vom Band 3 eine größere
Festigkeit hat. Weitere Vernadelungseinrichtungen 17 können folgen. Hier ist eine
reine Bandvernadelung oder auch eine mit Vernadelungstrommeln möglich.In all exemplary embodiments, the compacting
