Abstract (en)
Apparatus for opening tangled tobacco comprising one pair (12,13) of rotating rolls positioned across a flow path for tobacco, means to drive a one roll of the pair to convey the tobacco at a greater rate than the other roll, and the speed of the rolls being variable so as to regulate flow of the tobacco through the apparatus, a further pair (14,15) of rotating rolls, means to drive a one roll of the further pair to convey the tobacco at a greater rate than the other roll to thereby open the tangled tobacco, the arrangement being such that, in use, said tobacco passes from one pair of rolls to the other pair of rolls. <IMAGE>
