Abstract:
PCT No. PCT/CH95/00196 Sec. 371 Date Mar. 6, 1997 Sec. 102(e) Date Mar. 6, 1997 PCT Filed Sep. 6, 1995 PCT Pub. No. WO96/07460 PCT Pub. Date Mar. 14, 1996According to a method to remove dust particles from a stable material web which moves relative to a contact-free operating de-dusting device, a blower unit of the de-dusting device is provided at a specified first distance (d) and a grounded potential surface at a second distance (d) from the surface of the material web. The velocity and the pressure between the surface of the material and the potential surface of the ultrasonic gas flow existing from the blower unit is adjusted so that the product of the pressure and of the second distance (d) according to Paschen's law makes a discharge of the dust particles on the surface of the material feasible relative to the grounded potential surface. Furthermore, the adhesive forces (van der Waals forces) are overcome by the ultrasonic gas flow. Thus, these dust particles attached to the surface of the material are picked up by the ultrasonic gas flow without using electrically biased discharge electrodes, requiring electrical energy, and are removed by suction by at least one suction unit. The high operating expenses, required for equipment with electrically biased discharge electrodes, become superfluous with the described method.
