Abstract

In a process to transfer an incoming loose and weak web of non-woven staple fibre fleece from one roller drum to another, the fleece is held securely by air suction during take-up from the first drum and release to the second. Also claimed is an assembly in which a hot and loose fleece web is simultaneously cooled by air during the transfer process. The transfer is effected by a rotating sieve drum (19) from which air (26) is exhausted. The upper side of the drum is covered by a cap (27).

Description

In der DE-A-100 08 746 ist eine Kontinueanlage beschrieben, bei der das auf einer Krempel hergestellte Stapelfaservlies zur Verfestigung durch einen Kalander läuft und dann zur Weiterbehandlung auf ein Endlosband, auf dem das Krempelvlies mit einer Pulpschicht versehen und anschließend hydrodynamisch vernadelt wird. Es ist notwendig, das Vlies nach dem Kalandern zu kühlen, weswegen ein in der Anmeldung nicht genanntes Kühlwalzenpaar zwischen dem Kalander und dem Endlosband noch zwischenzuschalten ist. Im Falle der Nichtverfestigung des Vlieses durch das Kalanderwalzenpaar, im Falle dass also in der Kontinueanlage der Kalander offen von dem Vlies durchlaufen wird, ist das Stapelfaservlies nicht stabil genug, um ohne über einen die Fläche wirksamen Halt durch das Kühlwalzenpaar oder zum folgenden Endlosband laufen zu können.DE-A-100 08 746 describes a continuous system in which the on a Cardboard-produced staple fiber fleece runs through a calender and then for further treatment on an endless belt on which the carded fleece with a Pulp layer and then hydrodynamically needled. It is necessary, to cool the fleece after calendering, which is why in the registration not mentioned cooling roller pair between the calender and the endless belt yet is to be interposed. If the fleece is not consolidated by the pair of calenders, in the event that in the continuous system the calender is open from the If the fleece is run through, the staple fiber fleece is not stable enough to pass without one the surface effective hold by the cooling roller pair or to the following endless belt to be able to walk.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine dazugehörige Vorrichtung zu entwickeln, mit dem ein unverfestigtes, auch leichtes Stapelfaservlies fortlaufend von dem Walzenspalt eines Kalanderwalzenpaares bis hin zum weiterführenden Endlosband problemlos transportiert werden kann.The invention has for its object a method and an associated device to develop with which an unconsolidated, even light staple fiber fleece continuously from the nip of a pair of calenders to the next one Endless belt can be transported easily.

Zu Lösung dieser Aufgabe sieht die Erfindung vor, dass das Vlies von einem Luftdruck wie Unterdruck, der gegen ein Transportelement wirksam ist, erfasst und von diesem Unterdruck an dem Transportelement während der Übernahme und auch während der Übergabe gehalten wird. Dieser Unterdruck kann an einem Übergabeendlosband oder an einer Siebtrommel wirksam sein. Es ist besonders vorteilhaft, wenn bereits bei der notwendigen Übergabe das Vlies auch von Kühlluft durchströmt wird. To achieve this object, the invention provides that the fleece from an air pressure like negative pressure, which is effective against a transport element, detected by and from this Vacuum on the transport element during the takeover and also during the Handover is held. This vacuum can be on a transfer endless belt or be effective on a sieve drum. It is particularly advantageous if already at the necessary transfer the fleece is also flowed through by cooling air.

Eine entsprechende Vorrichtung zur Durchführung des Verfahrens ist in der Zeichnung schematisch dargestellt. Anhand dieser sollen weitere erfinderische Details erläutert werden. Es zeigen:

the same area as in Fig. 2 with a different embodiment of the transfer device.

Zunächst ist das Trägervlies aus den Polyesterfasern und/oder Polypropylenfasern od. dgl. herzustellen. Dazu dient als Vlieslegeeinrichtung eine Krempel 1 - 4. Die Krempel besteht aus einem Kastenspeiser 1 mit einer darunter angeordneten Schüttelrutsche 2, die die gleichmäßig über die Breite ausgebreiteten Fasern der Krempel mit den Kratz-und Reißwalzen 3 übergibt. Das folgende Endlosband 4 übergibt das gelegte Krempelvlies an eine Kalandereinrichtung 5, die hier aus einem einfachen Walzenpaar besteht. Die Verfestigungswirkung sollte nur gering sein, damit der Pulp mittels der Vernadelung noch eine innige Verbindung mit dem Krempelfaservlies eingeht.First, the carrier fleece is made of the polyester fibers and / or polypropylene fibers or To manufacture. A card 1 - 4 serves as a fleece laying device consists of a box feeder 1 with a shaker chute 2 arranged underneath it, which are the fibers of the card with the scratch and spread evenly across the width Tear rollers 3 passes. The following endless belt 4 passes the laid carding fleece to a calender device 5, which here consists of a simple pair of rollers. The strengthening effect should only be slight, so that the pulp by means of Needling still has an intimate connection with the carded fiber fleece.

Nach diesem Verfahrensschritt erfolgt wie bekannt die Aufgabe der Pulpfaser z. B. mit einer Vorrichtung 6 nach der EP-A-0 032 772. Dazu ist in der Kontinueanlage im Anschluss des Kalanderwalzenpaares 5 ein Endlosband 17 vorgesehen. Beide Vliesschichten zusammen werden dann zur Verbindung mit der hydrodynamischen Vernadelung 7 beaufschlagt, die auch auf demselben Endlosband 17 erfolgen kann. Der Trockenvorgang auf einer Siebtrommelvorrichtung 8, 9 mit Durchbelüftung schließt sich an. Bei der Vorrichtung 8 ist den Siebtrommeln der Ventilator direkt stirnseitig zugeordnet. Letztlich sollte noch eine weitere Kalandrierung mit dem Walzenpaar 15, 16 erfolgen, hier jedoch eine mit höherer Energie.After this step, the pulp fiber z. B. with a device 6 according to EP-A-0 032 772. This is followed in the continuous system of the pair of calender rolls 5 an endless belt 17 is provided. Both layers of fleece together then become the connection with the hydrodynamic needling 7 acted on, which can also take place on the same endless belt 17. The Drying process on a sieve drum device 8, 9 with ventilation closes itself. In device 8, the fan is directly assigned to the front of the screen drums. Finally, another calendering should be carried out with the pair of rollers 15, 16 done, but here with a higher energy.

Problematisch ist die Übergabe des Krempelvlieses 21 von dem Kalander 5 an das Endlosband 17. Wenn die Kalandrierung erfolgt ist, dann weist das Vlies 21 eine gewisse Festigkeit auf, die den Transport in ein Kühlwalzenpaar ermöglicht. Aber nicht immer ist eine Kalandrierung erwünscht oder die Festigkeit kann auch mit der Kalandrierung ungenügend sein. Um dieses Problem zu beseitigen ist gemäß der Fig. 2 eine Übergabe des Vlieses 21 mit einem zusätzlichen Endlosband 18 oder gemäß Fig. 3 mit einer unter Saugzug stehenden Siebtrommel 19 vorgesehen. Beide Lösungen haben den Vorteil, dass das sonst notwendige Kühlwalzenpaar entfallen kann.The transfer of the carding fleece 21 from the calender 5 to the is problematic Endless belt 17. When calendering has taken place, the fleece 21 has a certain one Strength that allows transport in a pair of chill rolls. But not Calendering is always desired or the strength can also be calendered be insufficient. To eliminate this problem, see FIG. 2 a transfer of the fleece 21 with an additional endless belt 18 or according to FIG. 3 with a suction drum 19 under suction. Both solutions have the advantage that the otherwise necessary pair of cooling rollers can be omitted.

Nach Fig. 2 ist oberhalb des Endlosbandes 17 das Übergabeendlosband 18 angeordnet, dessen erste Umlenkwalze 20 in Höhe des Spaltes zwischen den Kalanderwalzen 5 eingerückt ist. Dadurch wird zwar das Vlies 21 länger mit der unteren Walze des Kalanders 5 in Kontakt sein, was aber ohne Nachteil ist. Das Untertrum des Übergabeendlosbandes 18 ist dann weiter horizontal geführt und erstreckt sich so bis zur Ablaufwalze 22, der unterhalb des Endlosbandes 17 eine Absaugeinrichtung 23 folgen kann. Zwischen der Umlenkwalze 20 und der Ablaufwalze 22 ist oberhalb des Untertrums ein Saugkasten 24 angeordnet, der das Vlies 21 von unten gegen das Endlosband 18 zieht und es so problemlos zum Endlosband 17 bringt. Gleichzeitig kann das Vlies 21 von Kühlluft 25 durchströmt und bei erfolgter Kalandrierung gekühlt werden.2, the transfer endless belt 18 is arranged above the endless belt 17, whose first deflecting roller 20 at the level of the gap between the calender rollers 5 is indented. This makes the fleece 21 longer with the lower roller of Kalanders 5 in contact, which is without disadvantage. The lower strand of the handover endless belt 18 is then guided horizontally and thus extends to the drain roller 22, followed by a suction device 23 below the endless belt 17 can. Between the deflection roller 20 and the discharge roller 22 is above the lower run a suction box 24 is arranged, the fleece 21 from below against the endless belt 18 pulls and so it easily brings to the endless belt 17. At the same time it can Fleece 21 is flowed through by cooling air 25 and cooled when calendering has taken place.

Bei der Vorrichtung nach der Fig. 3 ist das Endlosband 18 durch eine unter Saugzug stehende Siebtrommel 19 ersetzt. Die Siebtrommel 19 ist so angeordnet, dass sie das Vlies 21 in einer mäanderförmigen Warenbahnführung übernimmt und auch wieder an das Endlosband 17 abgibt. Dazu ist die Siebtrommel 19 mit ihrer Achse etwa in Höhe des Walzenspaltes des Kalanders 5 angeordnet. Der Saugzug 26 gewährleistet einen problemlosen Transport und Übergabe des Vlieses 21 an das Endlosband 17. Dazu ist eine Innenabdeckung 27 über mehr als 180° so vorgesehen, dass sie an der Übergabelinie des Vlieses an die Siebtrommel und an die erste Umlenkwalze 28 des Endlosbandes 17 beginnt bzw. endet.In the device according to FIG. 3, the endless belt 18 is under suction standing drum 19 replaced. The screening drum 19 is arranged so that it Fleece 21 in a meandering web guide takes over and on again the endless belt 17 releases. For this purpose, the sieve drum 19 with its axis is approximately in height the nip of the calender 5 is arranged. The suction 26 ensures one easy transport and transfer of the fleece 21 to the endless belt 17. This is an inner cover 27 is provided over more than 180 ° so that it is at the transfer line of the fleece to the screen drum and to the first deflecting roller 28 of the endless belt 17 begins or ends.
