Abstract (en)

When manufacturing a cigarette which is completely or partly formed of strands or sides of expanded tobacco or short strands, or else containing a smaller amount of tobacco, difficulties are encountered in obtaining a cigarette which has an acceptable measured compressibility value. By providing a cigarette-manufacturing machine (1) with a cam (3) which has at least one additional bearing surface (32A, 33A, 34A, 35A) it is possible, just before the operation (15) of nipping the top off the twist (20), to compress a certain number of regions (22) of the said twist, thereby increasing the tobacco density in these regions. A cigarette including one or more regions (22) with a tobacco density which has been increased in this way has a measured compressibility value which is equivalent to a normal cigarette. <IMAGE>
