Abstract

Verfahren und Mittel zum Befreien eines Schleifbandes von festgesetztem Schleifstaub, wobei in bestimmten Zeit­ abständen der hin und her gehende Schleifschuh für kurze Zeit von der zu schleifenden Fläche des Profilstückes abge­ hoben wird, daß während des Abhebens des Schleifschuhes von der Profilfläche, zwischen dieser und dem Schleifpapier des Schleifschuhes ein Luftkissen aufgebaut wird, das im Anschluß schlagartig und in energischer Weise aus dem Raum, zwischen dem Werkstück und dem Schleifschuh, während der erneuten Rückbewegung des Schleifschuhes in Richtung des Profilstückes hin, verdrängt wird. Die erfin­ dungsgemäße Vorrichtung weist eine Hubvorrichtung auf, die mit dem hin und her gehenden Schleifschuh wirkverbun­ den ist sowie eine Druckluftquelle, die mit Zuführleitungen und/oder Strahldüsen, zur Zuführung von Druckluft zwi­ schen die Oberfläche des zu schleifenden Profilstückes und die untere, das Schleifpapier aufnehmenden Fläche des Schleifschuhes, versehen ist. Method and means for freeing an abrasive belt of fixed grinding dust, being in certain time intervals of the back and forth sanding shoe for short Abge time from the surface of the profile piece to be ground is raised that while lifting the grinding shoe from the profile surface, between this and the sandpaper an air cushion is built up of the grinding shoe, which in Suddenly and energetically connection from the Space between the workpiece and the grinding shoe, during the return movement of the grinding shoe in the direction of the profile piece, is displaced. The invent device according to the invention has a lifting device, that are effectively connected to the back and forth sanding shoe is as well as a compressed air source that with supply lines and / or jet nozzles, for the supply of compressed air between the surface of the profile piece to be ground and the lower surface of the sandpaper holding the Sanding shoe is provided.
