ABSTRACT:
An apparatus for dispensing material, especially tobacco, in portions of predetermined weight from a stream of irregular density. A variable speed feed system passes the material through a measuring region where its density is monitored and the feed speed is automatically adjusted to compensate for measured variation in the density to provide discharge of portions of predetermined weight from the feed system at regularly spaced time intervals. The relative separation positions of the portions may be calculated by determining the weight of each portion from both the density information and the feed speed, separation of the portions being effected when the separation position previously calculated reaches the end of the feed system.
