Description
Verfahren zur Herstellung von Schleifkörpern aus mit Schleifkorn belegten frei stehenden Fäden Die Erfindung betrifft ein Verfahren zur Herstellung von Schleifkörpern, deren Schleifteil aus mit Schleifkorn belegten frei stehenden Fäden besteht.Process for the production of abrasive bodies from coated with abrasive grain free-standing threads The invention relates to a method for the production of grinding wheels, whose grinding part consists of free-standing threads covered with abrasive grain.
Es ist bekannt, mit Schleifkorn belegte Textilfäden oder mit Schleifkorn durchsetzte Kunststoffäden auf einem Tragkörper zu befestigen. Hierbei werden einzelne oder mehrere Fäden mit Schleifkorn belegt und nach bekannten Verfahren einzeln oder in Gruppen auf dem Tragkörper von Schleifbürsten oder Schleifrädern befestigt. Diese Verarbeitung von einzelnen Schleiffäden ist zeitraubend und daher unwirtschaftlich.It is known textile threads covered with abrasive grain or with abrasive grain to fasten interspersed plastic threads on a support body. Here are individual or several threads covered with abrasive grain and individually or according to known methods attached in groups on the support body of grinding brushes or grinding wheels. These Processing of individual sanding threads is time-consuming and therefore uneconomical.
Erfindungsgemäß wird nun als Ausgangsmaterial für den Schleifteil ein Gewebe aus parallelen Kett-und einzelnen oder auch in Gruppen zusammengefaßten Schußfäden verwendet. Durch die einzelnen Schußfäden an den von Schußfäden sonst freien Stellen wird erreicht, daß die Kettfäden in gleichem Abstand gehalten werden können. Nach dem Belegen des Gewebes mit Klebstoff und Schleifkorn werden die Gewebe getrocknet und so getrennt, daß die Kettfäden frei stehende Fäden bilden, und die entsprechend zugeschnittenen Gewebestreifen durch Aufrollen, Übereinanderlegen oder Aneinanderreihen zu Schleifkörpern verleimt. Die getrockneten Gewebe können auch aufgerollt und später zu den gewünschten Schleifkörpern verarbeitet werden.According to the invention is now used as the starting material for the grinding part a fabric made of parallel warp and individual or combined in groups Weft threads used. By the individual weft threads to those of weft threads otherwise free places is achieved that the warp threads are kept at the same distance can. After covering the fabric with adhesive and abrasive grain, the fabric dried and separated so that the warp threads form free-standing threads, and the appropriately cut fabric strips by rolling up, laying on top of each other or Lined up glued to form grinding tools. The dried tissues can also rolled up and later processed into the desired grinding tools.
Beispiel Auf einem Webstuhl werden Kettfäden aus Textilfaser, Glasfaser, Draht, Hanf, Sisal, Papier, Kunststoff, Kunstfaser od. dgl. in einer Vorrichtung so gerichtet, daß zwischen den einzelnen Fäden etwa 1 bis 4 mm Abstand besteht. Um diese Kettfäden in gleichem Abstand zu halten, werden auf einer beliebig gewünschten Distanz Schußfäden eingezogen, wobei es für diese Gewebeform vorteilhaft ist, daß in Abständen von 20 bis 150 mm eine dichte Anordnung von Schußfäden erfolgt, etwa in Querstreifen oder Feldern von 20 bis 30 mm Breite.Example On a loom, warp threads made of textile fiber, glass fiber, Wire, hemp, sisal, paper, plastic, synthetic fiber or the like in one device directed so that there is a distance of about 1 to 4 mm between the individual threads. In order to keep these warp threads at the same distance, any desired Distance weft threads drawn in, it being advantageous for this fabric shape that a dense arrangement of weft threads takes place at intervals of 20 to 150 mm, for example in horizontal strips or fields 20 to 30 mm wide.
Das so erhaltene Gewebe wird auf bekannten Schleifpapierherstellmaschinen mit Klebstoff, Leim oder Kunstharzbindemittel bestrichen und mit Korn in bekannter Weise beiderseits bestreut.The fabric obtained in this way is made on known sandpaper-making machines Painted with glue, glue or synthetic resin binder and coated with grain in a familiar Way sprinkled on both sides.
Das so erhaltene Produkt wird auf Trockenstäben oder Trockenapparaten bekannter Art getrocknet, eventuell nochmals mit Klebstoff beiderseitig zur besseren Bindung der Körnung bestrichen und aufgerollt. Fig. A zeigt die Anordnung der Kettfäden a und Schußfäden b.The product obtained in this way is placed on drying sticks or drying machines Known type dried, possibly again with glue on both sides for better Binding of the grain coated and rolled up. Fig. A shows the arrangement of the warp threads a and weft b.
Man kann diese so hergestellten Bahnen zu Bogen so aufschneiden, daß die Quertrennschnitte durch die Mitte der Schußfädenfelder x1 und x3 sowie bei x2 laufen und die Längstrennschnitte in der gewünschten Breite erfolgen.You can cut these webs so produced into sheets so that the cross cuts through the middle of the weft fields x1 and x3 as well as at x2 run and the longitudinal cuts are made in the desired width.
Aus so zugeschnittenen Feldern lassen sich durch Aufrollen Pinsel nach Fig. B, Scheiben nach Fig. C oder teppichartige Schleifflächen durch Aneinanderreihen nach Fig. D herstellen.Brushes can be made from fields cut in this way by rolling them up according to Fig. B, disks according to Fig. C or carpet-like grinding surfaces by lining up Manufacture according to Fig. D.
