Abstract (en)
[origin: EP0913100A2] The method involve using a dispenser for micronized solids. An injector nozzle (26) pneumatically conveys the solids to a powder-chamber (34) through which the flat or fibrous filter material (32) is conveyed. The dispenser has a storage container (12) conveying discontinuously micronized solids, and has a gravimetrically operating fine-dispenser (14,16) which has a double worm for conveying the micronized solids to a pneumatically operating conveyor screw. Independent claims are also included for a device for carrying out the method.
