Method and apparatus for producing an elongated filler from fibers, especially tobacco fibers

摘要

The making of an elongated tobacco stream which is to be densified, wrapped and severed for conversion into discrete cigarettes is controlled in dependence on the height of the stream prior to removal of the surplus of tobacco. The control may be influenced by a parameter, such as the flow resistance of the stream prior to equalization or the height of the equalized stream. The control determines the distance between the plane in which the equalizer removes the surplus from the stream and a conveyor which advances the stream. The control signal for the desired position of the plane may be formed as a function of more than one parameter.
