Abstract
A cigarette-making machine in which tobacco, in part from a carding unit and in part from a plurality of channel elements, is supplied to the upper end of a shaft. The channel elements, to which recycled tobacco can be supplied, are located alongside one another and communicate laterally with the shaft below the shaft top. A vibrator device is associated with each channel element. The frequency of vibration of each vibrator is a function of the level of tobacco within the shaft beneath the tobacco delivery end of each channel element in communication with the shaft.
