Abstract
The ratio of different types of tobacco in a tobacco stream which is conveyed past a trimming device is monitored by monitoring the distance of the trimming plan from the conveyor for the stream while the mass flow of the stream is maintained at a constant value. Variations of the distance of the trimming plane from the conveyor are indicative of variations of the ratio of different tobaccos in the stream, and such variations are further indicative of fluctuations of filling power of tobacco which forms the stream.
