In order to improve the dielectrifying of the web so that 90-95% of dust, which is not mechanically adhered, will be relased from the web and can be sucked away, a further antistatic means (9) is placed between the slot of the air blower head (2) and the slot of the sponge (3). The antistatic means is of known construction and includes a surge diverter which is out of contact of the web. |
