Description

Verfahren zur Herstellung von Scheiben, Bremsbelägen u. dgl. Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Scheiben, Bremsbelägen u. dgl. Das Verfahren besteht darin, daß Faserstoffe, wie Fäden, Gewebe o. dgl., in bekannter Weise mit den bekannten durch Erhitzung von Phenol und Formaldehyd in Gegenwart eines Katalysators erhaltenen Kondensationsprodukten imprägniert und auf eine Spule o. dgl. aufgewickelt werden, worauf die so gebildeten Körper zu den gewünschten Formstücken zerschnitten werden; gegebenenfalls kann eine Pressung der gewickelten Körper vorgenommen werden. Die Imprägnierung der Faserstoffe kann auch nach dem Aufwickeln erfolgen.Process for the production of discs, brake linings and the like The invention is a method for the production of discs, brake pads and the like. The method is that fibrous materials, such as threads, fabrics o. The like., In known Way with the known by heating phenol and formaldehyde in the presence a catalyst obtained condensation products and impregnated on a spool O. The like. Are wound, whereupon the body thus formed to the desired Fittings are cut up; if necessary, a pressing of the wound Body are made. The impregnation of the fibers can also after Take place winding.

Es ist bekannt, Gegenstände in der angegebenen Weise aus imprägnierten Geweben herzustellen. Dagegen hat man bisher bei diesem Aufwickelverfahren noch nicht solche imprägnierten Gewebe als Ausgangsmaterial benutzt, bei denen die Phenol-Formaldehyd-Kondensationsprodukte als Imprägnierungsmittel dienen.It is known to impregnate objects in the specified manner To manufacture fabrics. On the other hand, one has so far still with this winding process such impregnated fabrics are not used as starting material, in which the phenol-formaldehyde condensation products serve as impregnation agents.

Durch die Anwendung dieses Ausgangsmaterials werden Scheiben u. dgl. von ganz außerordentlicherNt'iderstandsfähigkeit erhalten. Man erhält durch die ganz eng und dicht aneinanderliegenden Windungen, die in großer Zahl übereinanderliegen, ein dichtes gleichmäßiges Gefüge von holzartigem Aussehen, und die nach dem Zerschneiden erhaltenen fertigen Gegenstände können den höchsten, im praktischen Gebrauch vorkommenden L eanspruchungen ausgesetzt werden. Sie sind den aus anderen imprägnierten Geweben hergestellten gleichartigen Gegenständen weit überlegen.By using this starting material, discs and the like are produced. of quite extraordinary resistance. One obtains through the very tight and tightly spaced turns, which lie on top of each other in large numbers, a dense, uniform structure of woody appearance, and that after being cut up finished objects obtained can be the highest, occurring in practical use Be exposed to stress. They are made from other impregnated fabrics produced similar objects far superior.

Die Herstellung der gewickelten Körper geschieht in bekannter Weise. Die durch Zerschneiden in der gewünschten Gestalt erhaltenen Formstücke können als Scheiben zu verschiedenen Zwecken, z. B. als Ünterlegscheiben, als Beläge bei Kupplungen, Reibungsbremsen u.dgl., dienen. Sie können aber auch mannigfaltige andere Anwendung finden, z. B. als Dichtungen und Packungen bei Dampfleitungen und anderen Verbindungen und Maschinenteilen.The wound bodies are produced in a known manner. The shaped pieces obtained by cutting into the desired shape can be used as Discs for various purposes, e.g. B. as washers, as linings for clutches, Friction brakes and the like., Are used. But they can also be used in a variety of other ways find, e.g. B. as seals and packings for steam lines and other connections and machine parts.
