Vorrichtung zur Herstellung von Faserbändchen aus Papierstoff.
EMI1.1
Aufnahme und Verteilung der in einer Rund-oder Langsiebpapiermaschine erzeugten Faserbändchen dient. Wird diese Vorrichtung in der Weise benutzt, dass die Faserbändchen an der Unterseite des endlosen Tuches fortgeleitet werden, so ist es von grosser Wichtigkeit, dass die Faserbändchen bis zur Abgabestelle an dem Tuche haften bleiben. Bisher bediente man sich zu diesem Zwecke sogenannter Obertücher aus Schafwolle, und nur infolge der grossen Gewebedichtigkeit vermochte das Tuch an seiner abgesengten Oberfläche den Durchtritt der Luft durch das Tuch so wenig zu gestatten, dass die Haftfähigkeit gewahrt wird.
Bei zunehmender Entwässerung dieses Obertuches infolge des beim Passieren einer Walzenpresse erzeugten Druckes verliert das Tuch seine Adhäsionskraft, da eine entsprechend grössere Menge Luft durch das Tuch durchtreten kann. Bei zu starker Entwässerung hört die Verbindung vollkommen auf und die Faserbändchen fallen vorzeitig ab.
Um diesem Übelstand zu begegnen, kommt nach vorliegender Erfindung für den die Faserbändchen an seiner unteren Seite tragenden endlosen Abnahmefilz ein Filz zur Verwendung, der aus Baumwolle, Leinen, Hanf, Nessel, Asbest oder ähnlichem, eine grössere ansaugende Kraft als Wolle besitzenden Stoff verfertigt ist.
Von besonderer Wichtigkeit ist,'dass derartige Textilstoffe in ihrer Faser eine feinere Struktur bzw. eine derartige Oberflächenbeschaffenheit besitzen, dass sie das Kapillarwasser
EMI1.2
wendung eines aus derartigem Material gefertigten Abnahmefilzes ist man in der Lage, die Faserbändchen auf dem Filz beim Passieren der Walzenpresse so stark zu entwässern, wie es für die Faserbändchen erforderlich ist, um diese alsdann entweder unmittelbar zu Vorgarn zu verarbeiten oder auf Spulen aufzuwickeln.
Die Entwässerung kann bis zu 40 oder auch bis 50%,'vorgenommen werden, ohne dass. zu befürchten wäre, dass die'Faserbändchen von dem Filz unten abfallen, selbst wenn die Übe führung der Bahn vollkommen in wagrechter Lage vor sich geht.

Device for the production of fiber ribbons from paper stock.
EMI1.1
The purpose of receiving and distributing the fiber ribbons produced in a round or fourdrinier paper machine is to use. If this device is used in such a way that the fiber ribbons are carried away on the underside of the endless cloth, it is of great importance that the fiber ribbons adhere to the cloth up to the point of delivery. So-called upper cloths made of sheep's wool have been used for this purpose, and it was only because of the great density of the fabric that the cloth on its seared surface was not able to allow the air to pass through the cloth to such an extent that the adhesive force was preserved.
With increasing dewatering of this upper cloth as a result of the pressure generated when passing a roller press, the cloth loses its adhesive force, since a correspondingly larger amount of air can pass through the cloth. If there is too much drainage, the connection stops completely and the fiber ribbons fall off prematurely.
In order to counteract this inconvenience, according to the present invention, a felt is used for the endless removal felt carrying the fiber ribbon on its lower side, which is made of cotton, linen, hemp, nettle, asbestos or the like and has a greater suction power than wool .
It is of particular importance that such textile materials have a finer structure or such a surface quality in their fibers that they absorb capillary water
EMI1.2
Using a removal felt made of such a material, one is able to dewater the sliver on the felt as much as it is necessary for the sliver as it passes through the roller press, so that it can then either be processed directly into roving or wound onto bobbins.
The dewatering can be carried out up to 40% or even up to 50%, without having to fear that the fiber ribbons will fall off the felt below, even if the web is carried out in a completely horizontal position.
