Abstract

Ein Filzkörper, insbesondere ein Filzring als technisches Hilfsmittel für Polier- und Schleifarbeiten sowie ein Verfah­ ren zur Herstellung eines Filzkörpers sollen eine verbesserte Einsatzfähigkeit beim Schleif- und Poliervorgang ermögli­ chen. A felt body, especially a felt ring as a technical one Tools for polishing and grinding work and a procedure Ren for the production of a felt body should be an improved Can be used during grinding and polishing processes chen.

Hierzu enthält der Filzkörper (11, 21) zumindest 35% Wolle od. dgl. Haarelemente, und in Hohlräume seines Filzgewirrs sind Schleif- bzw. Polierkörner einer Korngröße unter 100 µm eingeschlossen. Zudem soll der nicht aus Wolle od. dgl. Haarelementen bestehende Anteil des Roh­ stoffes nicht mehr als 20 Volumenprozente betragen und/­ oder die Korngröße der Einschlüsse unter 250 µm liegen. For this purpose, the felt body (11, 21) contains at least 35% Wool or the like. Hair elements, and in the cavities of his Tangled fabrics are abrasive or polishing grains of one grain size included below 100 µm. In addition, it should not be out Wool or the like. Hair elements existing portion of the raw amount of no more than 20 percent by volume and / or the grain size of the inclusions is less than 250 µm.

Das Verfahren zeichnet sich dadurch aus, daß in Wasser­ schleifkörner mit einer Konzentration bis 500 gr je Liter H₂O, bevorzugt 20 bis 100 gr, eingebracht werden, daß dieses Gemisch als Arbeitsflüssigkeit in einen Rohling mit zumin­ dest 35% Wolle od. dgl. Haarelementen eingepreßt und dieser Filzkörper anschließend getrocknet wird. The process is characterized in that in water abrasive grains with a concentration of up to 500 gr per liter of H₂O, preferably 20 to 100 gr, that this Mix as working fluid in a blank with at at least 35% wool or the like. Hair elements pressed in and this felt body is then dried.
