With the features of claims 3 to 5 are the prerequisites for this improved that the stripped tobacco particles in preferred Directions are transported away without being destructive mechanical Exposed to stress.
  • Features of a further improvement in Removal device proposed according to the invention, which the generation of Improved compressed sections in the tobacco rod are included in claim 6. Because the washers are no pockets for the circular knife Formation of head reinforcements in the tobacco rod can have, according to the invention necessary for the head reinforcements of the cigarettes Compaction of the strand generated by the rotating eccentric.
  • Claim 6 gives a particularly advantageous arrangement of the eccentric Tobacco rod compression. This is chosen according to the invention so that the compressed sections in the tobacco rod until the excess is removed cannot expand again. In order to achieve the most uniform compression possible To ensure tobacco rod, the features of claim 7 are provided. Claims 8 and 9 relate to preferred designs of the deflector element.
  • the invention has the advantage that the excess of a tobacco rod in a cigarette rod machine can be removed very gently, so that the removed excess tobacco without additional loss of quality the strand structure can be traced. At the same time, the removed one Excess tobacco is directed in a certain direction and can continue without loss be used. The ones necessary for the head reinforcement of the cigarettes Compression of the tobacco rod are generated very evenly and are designed so that when wrapping the tobacco rod with a cigarette paper do not require any additional deformation work. Because of of the compact structure of the removal device according to the invention the compression generated in the strand remains until the excess decrease optimally preserved. Overall, the removal device ensures according to the invention the manufacture of a tobacco rod high quality and uniformity with low technical effort.
