ABSTRACT:
The height of a continuous tobacco stream between a first side which is supported by a conveyor and an uneven second side is monitored by an opto-electrical level detector which directs a row of parallel light rays transversely across the stream and has a battery of photosensitive elements at different distances from the first side of the stream so that each element produces a signal in response to impingement of a different light ray upon its photosensitive surface. The number of elements which generate signals is indicative of the height of the stream portion advancing past the level detector. Such signals can be utilized to adjust a trimming device which removes the surplus at the second side of the stream before the thus equalized stream enters a wrapping mechanism to be converted into a cigarette rod which is thereupon severed to yield discrete cigarettes.
