Abstract
A machine wherein a mobile partition divides a flow of tobacco particles into several streams each of which carries a surplus of tobacco particles. The surplus is removed from the streams by discrete trimming devices to convert the streams into fillers which are draped into webs of cigarette paper. The removed surplus is measured independently for each stream and the signals which are generated to denote the quantities of removed surplus are used to change the position of the partition in a sense to ensure that each stream contains a predetermined quantity of surplus. A device which monitors the density of at least one filler generates signals serving to adjust the trimming devices in a sense to ensure that the density of all fillers matches a preselected density.
