Abstract
Tobacco particles which escape from plain cigarettes and/or filter cigarettes in machines for the making of plain and filter cigarettes are partially separated from streams of suction air before such streams reach the main separator. This relieves the main separator so that the latter necessitates less frequent cleaning and/or replacement of filters. In a filter cigarette making machine with or without a main separator, one or more separators for reusable tobacco particles can be installed to collect reusable particles which escape at one, two or more stations where the escape of tobacco is likely and pronounced. Such separators employ suction fans, vessels below the respective units, and pipes which convey the contents of vessels to a tobacco removing device upstream of the fans.
