Abstract
A process for cleaning an abrasive belt using an air blade extending continuously over the entire working width, or several segmented air blades, as well as a device which encloses this air blade or these air blades having an extraction hood serving to guide away the dust-laden air. If this device is used for a belt grinding machine equipped with a workpiece vacuum device, the air supply requirements are optimised by use of a diverter to reduce the number of fans.

A process for blowing off an abrasive belt for the purpose of cleaning it during the abrasion process, wherein a stream of air acting on the abrasive belt is generated by an air blade.
An air blade for blowing off an abrasive belt, wherein it has an extraction hood having one or more openings and a discharge pipe for recirculation of grinding dust-laden air from the grinding machine interior enclosing the air blade.
An air blade for blowing off an abrasive belt, wherein air supply of the air blade occurs multilaterally.
An air blade for blowing off an abrasive belt, wherein it is part of a grinding unit having a workpiece vacuum clamping device, and it draws air entering the grinding unit across the perforations of the feed table and of the conveyor belt of this vacuum clamping device.
