Abstract (en)
[origin: WO2022269307A1] The invention relates to a method for cleaning an abrasive belt by means of an air knife extending continuously over the entire working width or by means of a plurality of segmented air knifes, and to a device that surrounds said air knife or said air knives with an extraction hood (8) used to lead away the dust-laden air. If said device is used for a belt grinding machine that is equipped with a workpiece vacuum device, the expenditure for the air supply is reduced to a lesser need for fans by virtue of the use of a diverter.
