No. 4,867,180 disclose a tobacco feed device for a cigarette production machine, in which jammed tobacco is removed from a stowage shaft by means of two metering rollers and is separated and separated by means of an opening roller. The tobacco is compressed between the metering rollers, whereby the fiber structure of the tobacco can be destroyed by mechanical force.
