Abstract: The invention relates to a method for the separation of foreign bodies and a device for the separation of foreign bodies from a tobacco stream. The method according to the invention is characterized in that the tobacco stream is directly conveyed into the area of the foreign-body detection device with compressed air and whereby foreign bodies in the tobacco stream are identified by means of the foreign-body detection device based on at least one characteristic and subsequently removed from the tobacco stream. The A device according to the invention is characterized in that a device (feeding device) feeding the tobacco to a foreign-body detection device and a foreign-body separation device are provided, whereby the tobacco feeding device for conveying the tobacco stream comprises a source of compressed air.

Abstract: The application relates to a conveying arrangement for a machine in the tobacco-processing industry having a conveying apparatus which has a plurality of conveying elements moving in a conveying direction for conveying and/or separating a fibrous product and is characterised in that in the region of the conveying elements the conveying arrangement comprises at least one fixed nozzle for blowing in a medium in a direction counter to the conveying direction.

Abstract: The application relates to an apparatus for conditioning a tobacco product having a transport pipe through which a process gas flows and which has a feed section having a feed opening for feeding in the product and a following drying section, characterised in that the transport pipe has dividing means for dividing, before the feed opening, the stream of process gas into a substream picking up the product and a substream which is substantially product-free and for bringing the substreams together at the beginning of the drying section so that the product is introduced into the drying section in the inner region of the transport pipe.

Abstract: The invention relates to a method of segregating foreign particles from a tobacco flow. The invention moreover relates to an apparatus for segregating foreign particles from a tobacco flow, which comprises a first conveyor feeding the tobacco to a device for detecting foreign particles as well as a device for segregating foreign particles. The apparatus according to the invention is characterized by the following steps of operation: conveying tobacco by means of a first conveyor, with the tobacco being held on said first conveyor by means of suction air, detecting foreign particles in said tobacco flow constituted by the conveyed tobacco in the zone of said first conveyor or downstream of said first conveyor, and segregating detected foreign particles from said tobacco flow. The apparatus according to the invention is characterized by the feature that the first conveyor is configured for holding tobacco by suction air.

Abstract: Particles of non-smokable material are segregated from a flow of a mixture of smokable and non-smokable materials by subjecting the flow to a first segregating treatment which divides the flow into a first stream consisting practically exclusively of smokable material, and a second stream constituting a relatively small percentage of the flow and containing substantially all of the non-smokable material and the remnant of smokable material. The second stream is treated for a second time, preferably at the discharge end of a pneumatic conveyor system including at least one conduit, to segregate the non-smokable material from the remnant of smokable material which latter can be admitted to the first stream. The segregating device which divides the flow into the first and second streams is or can be utilized to treat the second stream, i.e., to segregate smokable material of the second stream from the non-smokable material of the second stream.

Abstract: A dryer for drying a tobacco product including a drying device structured and arranged to dry the tobacco product passing through the drying device. The dryer further including a measuring device arranged to produce a measurement signal related to an input moisture of the tobacco product before the tobacco product is supplied to the drying device. Moreover, the dryer includes a controller structured to variably control a product mass stream passing through the drying device as a function of the measurement signal. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Tobacco dust which develops in a machine or production line for the making of smokers' products is put to use in that it is gathered and agglomerated into particles having or exceeding a required size. Metered quantities of such particles are admitted into a stream of fragmentized tobacco leaves before the stream is draped into a web of cigarette paper or the like.
