Verfahren zum Herstellen eines Gegenstandes aus einem porösen faserigen Material.A method of making an article from a porous fibrous material.
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Gegenständen aus porösen faserigen Materialien und insbesondere auf ein Verfahren zum Bearbeiten von Gegenständen, die aus einem solchen Material hergestellt sind, wobei die Gegenstände eine Gestalt erhalten sollen, die in einfacher We'ise unter Verwendung der bekannten Herstellungsverfahren für solche Materialien bisher nicht hergestellt werden konnte.The invention relates to a method of making articles from porous fibrous materials and in particular to a method for processing objects made of such a material, whereby the objects are to be given a shape that can be produced in a simple manner using the known manufacturing processes for such materials could not be produced so far.
Der Zweck der Erfindung besteht darin, ein Verfahren zuThe purpose of the invention is to provide a method
schaffen, das eine präzise Herstellung von Gegenständencreate the precise manufacture of objects
auch mit verhältnismäßig komplizierter Gestalt aus einem porösen faserigen Material ermöglicht.also made possible with a relatively complicated shape made of a porous fibrous material.
Das Verfahren gemäß der Erfindung ist dadurch gekennzeichnet, daß das Material zunächst mit einer gefrierbaren Flüssigkeit imprägniert wird, hierauf die Flüssigkeit in de-n Material ausgefroren und das Material auf die erforderliche Gestalt bearbeitet wird, wonach das Material erwärrrt und die Flüssigkeit darin aufgetaut wird.The method according to the invention is characterized in that that the material is first impregnated with a freezable liquid, then the liquid Frozen out in the material and the material to the required Shape is processed, after which the material is heated and the liquid in it is thawed.
Das Verfahren gemäß der Erfindung soll anhand der beiliegenden Zeichnung näher erläutert werden.The method according to the invention will be explained in more detail with reference to the accompanying drawing.

Fig. 1 einen Schnitt durch einen Ring zum Abdichten gegen Staub, der nach dem Verfahren gemäß der Erfindung hergestellt ist undFig. 1 is a section through a ring for sealing against dust, which is produced by the method according to the invention and
Fig. 2 einen Teilschnitt durch ein anderes AusfUhrungsbeispiel eines solchen Ringes.2 shows a partial section through another exemplary embodiment such a ring.
Der in den Zeichnungen dargestellte Ring zum Abdichten gegen Staub soll ringförmig ausgebildet sein und einen Körper 10 mit im wesentlichen rechteckigen Querschnitt besitzen, der eine innere Rippe 10 aufweist. In dem.Ausflihrungsbeispiel, das in Fig. 2 dargestellt ist, ist der Körper aus zwei Teilen ausgebildet, die miteinander mittels eines bekannten Verfahrens befestigt sind und der einen ringförmigen Tragring 12 enthält, der zwischen den beiden Teilen zwischengesetzt ist. In den Fällen, in denen der Ring zum Abdichten gegen Staub einer mit Gewinde versehenen Welle verwendet werden soll, muß die Rippe 11 wendelförmig ausgebildet sein.The ring shown in the drawings for sealing against dust should be annular and one Have body 10 with a substantially rectangular cross-section, which has an inner rib 10. In the example, which is shown in Fig. 2, the body is formed from two parts which are connected to each other by means of of a known method and which includes an annular support ring 12 interposed between the two Share is interposed. In those cases where the ring is threaded to seal against dust Shaft is to be used, the rib 11 must be helical.
Der Körper und der Ring werden aus einem porösen faserigen Material, beispielsweise aus Filz hergestellt und sind schwierig mit der erforderlichen Genauigkeit auszuformen, wobei bekannte Verfahren zum Bearbeiten von Filz verwendet werden. Indessen beim Verwenden des Verfahrens gemäß der Erfindung wird der Ring zunächst roh aus einem Filz mittels eines Messers ausgeschnitten und dann mit Wasser imprägniert. Der roh ausgeschnittene Ring wird dann auf eine sehr niedrige Temperatur gebracht, die genügend tief ist, so daß das Wasser in dem Körper vollständig gefriert, worauf dann die Rippe genau mit bekannten Bearbeitungsverfahren ausgeschnitten wird. Das gefrorene Wasser hält die Fasern, die den Filz bilden, fest und wenn die Bearbeitung beendet worden ist, wird der Ring erwärmt, indem er in einen warmen Raum eingebracht wird oder indem er Wärme ausgesetzt wird, wobei das Wasser auftaut. Schließlich wird der Ring getrocknet, um das darin enthaltene Wasser zu entfernen und kann nun seinem Verwendungszweck zugeführt werden.The body and the ring are made of a porous fibrous material such as felt difficult to shape with the required accuracy using known methods of working felt will. Meanwhile, using the method according to the invention, the ring is first made raw from a felt by means of cut out with a knife and then impregnated with water. The roughly cut ring is then put on a brought to a very low temperature, which is sufficiently low that the water in the body freezes completely, whereupon then the rib precisely using known machining methods is cut out. The frozen water holds the fibers that make up the felt firmly and when working has been completed, the ring is heated by placing it in a warm room or by exposing it to heat thawing the water. Finally, the ring is dried to remove the water it contains and can now be used for its intended purpose.
