<p>The invention relates to apparatus for removing foreign matter from a stream of particulate material as part of the processing of that material; and finds particular but not exclusive use in the removal of foreign matter such as paper or other items from a stream of tobacco material as part of the pre-processing of tobacco in the manufacture of cigarettes. The apparatus for removing foreign matter from a stream of material comprises conveyor means arranged to carry the stream of material from an inlet (16), successively past an agitation stage (20) in which the material is agitated to spread it evenly over the conveyor means, a detection stage (21) at which foreign matter is detected optically, and an ejection stage (22) at which detected foreign matter is removed from the material, and is delivered to an exit (18) from the apparatus.</p> |
