Die beiden nachgeschalteten, mit der ersten Arbeitstrommel im Eingriff stehenden Arbeitstrommeln bewirken eine Aufteilung des von der ersten Arbeitstrommel gebildeten Flores, wobei die Flore auf nachgeschalteten Transportbändern wieder dubliert werden.From EP-A-0 330 750 a tangled nonwoven card is included at least three rotating in the same direction as the master cylinder Working drums known in which the first working drum is engaged with the master cylinder while the two further working drums each with the first Work drum are engaged. The two downstream, engaged with the first working drum Working drums divide the from the first working drum formed Flores, the Flore duplicated again on downstream conveyor belts become.
Es sind ferner Krempelanlagen der Firma Hergeth Hollingsworth bekannt (Krempel Modell H 6.345), in denen zwei Wirrwalzen mit einem Hauptzylinder im Eingriff sind, die jeweils einen Wirrfaserflor erzeugen, der letztlich auf je ein Transportband abgelegt wird. Das Dublieren der beiden Wirrfaserflore erfolgt durch Zusammenführen der beiden Flore auf dem Transportband.There are also carding machines from Hergeth Hollingsworth known (card model H 6.345), in which two Tangled rollers are engaged with a master cylinder that each create a tangled fiber web, which ultimately depends on each a conveyor belt is put down. Duplicating the two Tangled fibers are made by merging the two Flore on the conveyor belt.
Das so erzeugte Vlies besteht aus zwei Florlagen, die nachteiligerweise nur lose aufeinanderliegen und nicht miteinander vernetzt sind. Eine Verbindung der Lagen erfolgt erst in einer oder mehreren der Krempel nachfolgenden Verarbeitungsstufen.The fleece produced in this way consists of two layers of pile, the disadvantageously only lie loosely on top of each other and not are networked with each other. The layers are connected only in one or more of the clutter following Processing stages.
Aus der FR-A-331 414 ist eine gattungsgemäße Vlieskrempel bekannt, bei der dem Tambour zwei Walzen nachgeordnet sind, die jeweils einen Teil des Vlieses abnehmen und auf eine Kämmwalze übertragen. Dadurch soll ein besonders gleichmäßiges Vlies erzeugt werden.FR-A-331 414 is a generic fleece card known, in which two reels are arranged after the drum are, each take off and on a part of the fleece transferred a combing roller. This is said to be a special one uniform fleece can be produced.
Aus FR-A-1 138 108 ist desweiteren eine Karde bekannt, bei der zwei Zwischenabnahmewalzen mit der Haupttrommel im Eingriff sind und jeweils einen Faserflor auf eine Endabnahmewalze übertragen.A card is also known from FR-A-1 138 108 of the two intermediate take-off rolls with the main drum in the Are engaged and each a pile of fibers on a final take-off roller transfer.
Der Erfindung liegt die Aufgabe zugrunde, eine Vlieskrempel der gattungsgemäßen Art, sowie ein Verfahren zur Vliesherstellung zu schaffen, bei denen bereits eine Vernetzung des hergestellten Vlieses in der Krempel erfolgt und bei denen der Herstellprozeß, insbesondere bei leichten Floren und hohen Produktionsgeschwindigkeiten besser kontrollierbar ist. The invention has for its object a fleece card of the generic type, and a method for Create nonwovens that already have networking of the fleece produced in the card and where the manufacturing process, especially light ones Flores and high production speeds better is controllable.
Zur Lösung dieser Aufgabe dienen die Merkmale der Patentansprüche
1 bzw. 14.The features of the claims serve to solve this
Die Erfindung sieht in vorteilhafter Weise vor, daß die mindestens eine, zwischen Hauptzylinder und der mindestens einen Dofferwalze angeordnete, florbildende Walze eine Wirrwalze ist. The invention advantageously provides that the at least one, between the master cylinder and the at least one doffer roller arranged, pile-forming roller is a tangled roller.
Eine derartige Vlieskrempel ermöglicht eine Dublierung und gleichzeitige Vernetzung bereits in der Krempel nach den florbildenden Walzen und vor der Abnahmeeinrichtung. Ein weiterer Vorteil besteht darin, daß hinter der Dofferwalze nur noch eine einzige Abnahmeeinrichtung und nur ein einziges Transportband benötigt werden. Auf diese Weise ist der konstruktive Aufwand für die Herstellung von dublierten Faserfloren reduziert, wobei der Herstellprozeß, insbesondere bei leichten Floren und hohen Produktionsgeschwindigkeiten besser kontrollierbar ist.Such a fleece card enables duplication and simultaneous networking already in the clutter after the pile-forming rollers and in front of the removal device. A Another advantage is that behind the doffer roller only one single acceptance device and only one Conveyor belt are needed. That way the constructive effort for the production of duplicates Reduced fiber pile, the manufacturing process, in particular with light floras and high production speeds is more controllable.
Bei einem Ausführungsbeispiel der Erfindung ist in vorteilhafter Weise vorgesehen, daß eine einzige Dofferwalze mit zwei florbildenden Walzen im Eingriff ist, von beiden Walzen jeweils einen Faserflor übernimmt und die Faserflore dubliert. Das Dublieren erfolgt unmittelbar hinter den florbildenden Walzen, so daß nur eine einzige Dofferwalze benötigt wird.In one embodiment of the invention is advantageous Way provided that a single doffer roller is engaged with two pile-forming rollers, by both Rolling each takes over a batt and the batt duplicated. Duplication takes place immediately behind the pile-forming rollers, so that only one Doffer roller is required.
Gemäß einem weiteren Ausführungsbeispiel der Vlieskrempel mit je einer einer florbildenden Walze nachgeordneten Dofferwalze ist vorgesehen, daß eine einzige Stauchwalze mit beiden Dofferwalzen im Eingriff ist und von beiden Dofferwalzen je einen Faserflor übernimmt und die Faserflore dubliert. Bei dieser Variante der Erfindung erfolgt das Dublieren erst hinter der Doffereinrichtung, und zwar an der ersten Stauchwalze einer Staucheinrichtung. Auch bei diesem Ausführungsbeispiel erfolgt eine Reduzierung der erforderlichen Maschinenelemente, da hinter der Doffereinrichtung nur eine Abnahmeeinrichtung und ein einziges Transportband benötigt werden. Auch dieses Ausführungsbeispiel eignet sich insbesondere zur Herstellung von leichten dublierten Faservliesen bei hoher Produktionsgeschwindigkeit. According to a further embodiment, the fleece card with one downstream of a pile-forming roller Doffer roll is provided that a single upsetting roll is engaged with both doffer rollers and by both Doffer rolls each take over a batt and the batt duplicated. In this variant of the invention duplication only behind the doffer device, namely on the first upsetting roller of an upsetting device. Also in this embodiment there is a reduction of the required machine elements, since behind the doffer device only one acceptance device and one Conveyor belt are needed. This embodiment too is particularly suitable for the production of light doubled non-woven fabrics at high production speed.
Ein weiteres Ausführungsbeispiel der Vlieskrempel weist eine mit dem Hauptzylinder im Eingriff befindliche und mit diesem gleichsinnig rotierende florbildende Walze sowie eine ebenfalls als florbildende Walze verwendete, gegenläufig zu dem Hauptzylinder rotierende Dofferwalze auf. Die Wirrwalze und die Dofferwalze nehmen je einen Flor von dem Hauptzylinder ab, wobei der florbildenden Wirrwalze eine gegenläufig rotierende Dofferwalze zugeordnet ist. Eine einzige Stauchwalze ist mit beiden Dofferwalzen im Eingriff und übernimmt von beiden Dofferwalzen je einen Faserflor, der auf der Stauchwalze dubliert wird. Dieses Ausführungsbeispiel ermöglicht die Vernetzung von zwei strukturell unterschiedlichen Floren über einen Stauchprozeß.Another embodiment of the fleece card has one in engagement with the master cylinder and with this in the same direction rotating pile-forming roller as well an opposite also used as a pile-forming roller to the master cylinder rotating doffer roller. The tangled roller and the doffer roller each take a pile of from the master cylinder, whereby the pile-forming tangled roller a counter rotating doffer roller is assigned. A single upsetting roller is with both doffer rollers in the Intervention and takes over from each of the two doffer rollers Fiber web that is duplicated on the upsetting roller. This Embodiment enables the networking of two structurally different floras via a compression process.
Eine Variante des zuletzt genannten Ausführungsbeispiels besteht darin, daß die Staucheinrichtung zwei erste Stauchwalzen aufweist, die jeweils mit einer Dofferwalze im Eingriff sind, wobei die Faserflore auf einer zweiten Stauchwalze dubliert werden, die mit beiden ersten Stauchwalzen im Eingriff ist.A variant of the last-mentioned embodiment is that the upsetting device two first Compression rollers, each with a doffer roller are engaged, the fibrous web on a second The upsetting roller can be duplicated with the first two upsetting rollers is engaged.
Ein weiterer Vorteil der beschriebenen Ausführungsbeispiele besteht darin, daß auf dem Umfang des Hauptzylinders mehr Platz für Arbeiterwenderpaare oder feststehende Kardiersegmente verbleibt.Another advantage of the described exemplary embodiments is that on the circumference of the master cylinder more space for pairs of workers and fixed carding segments remains.
Bei einer Weiterbildung der Erfindung mit einer einzigen dem Hauptzylinder nachgeschalteten florbildenden Walze und einer dieser florbildenden Walze nachgeschalteten Dofferwalze ist vorgesehen, daß die Dofferwalze sowohl mit der vliesbildenden Walze als auch mit dem Hauptzylinder im Eingriff ist, von jeder Walze je einen Faserflor übernimmt und die Faserflore dubliert. In a development of the invention with a single the pile-forming roller downstream of the master cylinder and one downstream of this pile-forming roller Doffer roller is provided that the doffer roller both with the fleece-forming roller as well is engaged with the master cylinder, depending on each roller takes over a pile and duplicates the pile.
Bei einer derartigen Vlieskrempel ist die Anzahl der erforderlichen Maschinenelemente noch weiter reduziert, wobei die Faserflore auf der einzigen Dofferwalze dubliert werden, die einen Faserflor direkt von dem Hauptzylinder und einen weiteren Faserflor von der florbildenden, mit dem Hauptzylinder im Eingriff befindlichen Walze übernimmt.In the case of such a fleece card, the number is required Machine elements reduced even further, the fiber pile duplicating on the single doffer roller that have a batt directly from the master cylinder and another fiber pile from the pile-forming, with the master cylinder engaged roller takes over.
Die Dofferwalze übernimmt demzufolge einerseits die Funktion der florbildenden Walze und die Funktion des Dublierens von zwei unterschiedlich erzeugten Faserfloren. Der Herstellprozeß benötigt daher nur eine florbildende, Wirrwalze und eine einzige Dofferwalze, wodurch gegenüber den vorgenannten Ausführungsbeispielen eine weitere Walze eingespart werden kann.The doffer roller therefore takes over the function on the one hand the pile-forming roller and the function of duplication of two differently produced fiber pile. Of the Manufacturing process therefore only requires a pile-forming, Tangled roller and a single doffer roller, whereby compared to the aforementioned embodiments additional roller can be saved.
Es versteht sich, daß z.B. eine weitere Wirrwalze zugleich mit dem Hauptzylinder und der Dofferwalze im Eingriff sein kann, wodurch drei Faserflore auf der Dofferwalze dubliert werden können.It is understood that e.g. another tangled roller at the same time be engaged with the master cylinder and the doffer roller can, causing three fiber webs to be duplicated on the doffer roller can be.
Dabei sind dublierte Faserflore herstellbar, die eine Kombination von einem Wirrfaserflor und einem längsorientierten Vlies darstellen. Es ist ein Faserflor mit inniger Vernetzung herstellbar.Duplicated fiber webs can be produced, one Combination of a tangled fiber pile and a longitudinal one Represent fleece. It is a fiber pile with an intimate Networking can be established.
Weitere vorteilhafte Merkmale sind den Unteransprüchen zu entnehmen. Further advantageous features can be found in the subclaims remove.
