ABSTRACT:
A probe is employed for removing dust from moving webs, paper webs for example. It has at least one electrostatic high-voltage electrode, at least one blower for gas, preferably air, oriented against the direction that the web travels in, and a vacuum channel for suctioning up the dust-laden gas. The pointed or blade-shaped subsidiary electrodes in the high-voltage electrode (10) lie in a plane that does not parallel the web (7). The direction that the row of round and/or slotted nozzles (12) in the blower (11) blow along lies in another plane downstream of the high-voltage electrode (10). The two planes intersect at a line that lies in the plane of the web (7) and extends across it. The round and/or slotted openings (14) into the vacuum channel (13) are on the other hand positioned upstream of the high-voltage electrode (10) in the web-travel direction (8).
