Abstract

Ein Schwingschleifer (1) enthält an der Unterseite (16) seines Schleifschuhs (3) mehrere Absaugöffnungen (37), die am Rand des Schleifschuhs (3) angeordnet sind. An orbital sander (1) contains on the underside (16) of its grinding shoe (3) several suction openings (37), which are arranged on the edge of the grinding shoe (3).

Damit der Schleifstaub auch in dem mittleren Bereich zwischen den Reihen von Absaugöffnungen (37) wirksam be­ seitigt werden kann, befindet sich etwa in der Mitte des Schleifschuhs (3) eine weitere Öffnung (42), die über einen Kanal hin belüftet ist und nicht an das Gebläse für die Absaugöffnungen angeschlossen ist. So that the sanding dust also in the middle area be effective between the rows of suction openings (37) can be to the side, is located approximately in the middle of the grinding shoe (3) a further opening (42), the is ventilated through a duct and not to the Fan for the suction openings is connected.
