Abstract
Apparatus for producing a narrow tobacco stream ready for trimming or immediate wrapping into a web of cigarette paper has a distributor from which a wide first belt or a plate transports a thin carpet of tobacco particles to a first transfer station where the carpet is transferred by suction and preferably also by compressed air onto a narrower foraminous second belt forming part of an intermediate conveyor with an independent drive. The second belt is inclined with respect to and narrower than the first belt or plate and accumulates a layer of tobacco particles which are attracted to the second belt by a suction chamber extending from the first transfer station to a second transfer station where the layer is transferred onto a foraminous third belt to form thereon a narrow stream. A second suction chamber attracts the stream to the third belt during transport from the second transfer station to a third transfer station where the stream is transferred onto a web of cigarette paper moving with one stretch of the garniture and is thereupon caused to pass through a wrapping mechanism. The transfer of tobacco from the second onto the third belt is assisted by compressed air. Repeated transfer of tobacco by suction and compressed air contributes to homogenization of tobacco during conversion of the carpet into the stream.
