Abstract
The moisture content of the fillers of cigarettes is maintained at a preselected value by feeding to the stream building zone of the cigarette rod maker a flow of tobacco particles whose moisture content exceeds the desired value and with a surplus which is removed by an adjustable trimmer to convert the flow into a trimmed stream which is ready for draping into a web of cigarette paper to form a cigarette rod which is subdivided into cigarettes of desired length. The removed surplus is heated by a drying device and the heated surplus with its reduced moisture content is returned into the distributor of the cigarette rod maker to be admixed to the already advancing flow of fresh tobacco particles whose moisture content is excessive. The heating action is regulated as a function of signals generated by one or more moisture detectors which can monitor the moisture content of fibrous material in the surplus prior or subsequent to drying and/or the moisture content of the filler or trimmed stream.
