Method and arrangement for forming a rod of smokable fibres, preferably consisting of tobacco

摘要

In the formation of a tobacco rod (7) for cigarettes (15), excess tobacco fibres are removed by a leveller (8) arranged at a defined, invariable distance from a rod conveyor (3). As a function of density measurement signals, preferably obtained on the compacted and wrapped rod (7b), the conveying speed of the rod conveyor, which is driven faster than the compacting conveyor (format belt) (13), is controlled. <IMAGE>
