摘要

The quality regulation system controls at least two physical parameters which effect the quality of the obtained cigarattes by comparing the actual and required parameter value to provide regulation signals for the tobacco or filter mass in dependence on the obtained difference values. During an initial phase, only one primary product parameter is measured and adjusted. The required value for the second parameter is calculated during this initial phase, with subsequent switching in of the regulation for the second product parameter. The primary product parameter may comprise the weight or the dia. of the tobacco stream. The second parameter comprises the hardness, the tensile resistance and/or the dia. of the tobacco stream.
