- FIG. 1 shows a schematic longitudinal section through a section of a distributor of a schematically designated double-strand cigarette machine P, which has a strand forming device S, by means of which tobacco strands are formed.
- the structure and operation of the distributor shown in Fig. 1 or part of a distributor V for a Doppelstrangzigaret- tenmaschine P are as follows:
- Tobacco is usually conveyed from an upward conveyor, not shown in FIG. 1, into a stowage bay 216 in which a tobacco supply 217 thus accumulates.
- Tobacco stock 217 in stowage bay 216 is monitored by light barriers, which are not shown. This is the removal conveyor in the sense of
- the tobacco is removed by means of a removal device.
- the removal device consists of a removal roller 221 and a racket roller 222 with respect to the removal roller
- the removal roller 221 greatly increased speed.
- the removal roller 221 is with spines 223, the relatively fast rotating club roller
- Chill 226 made of tobacco fibers passes in the direction of arrow 227 in a funnel-shaped narrowing Zuglassfallschacht in the form of a channel 228, in which a Blasluftdüse 307, which is connected to an air box 308, is arranged.
- the blast air nozzle 307 blows air between the wall 316 of the well 228 and the tobacco blast 226, such that the tobacco in the tobacco blast 226 is compressed.
- a compression takes place in a further embodiment, not shown, without the Blas Kunststoffdüse 307. Furthermore, air gets on the walls
- Leitflä- Chen 310 suppress cross-components of the air flow, whereby a more uniform distribution of tobacco is achieved.
- the tobacco shower consists of pre-sighted tobacco fibers.
- a classifying air stream is usually used, which blows transversely to the conveying direction, for example a tobacco gob.
- the light tobacco fibers consisting of long tobacco fibers and short light tobacco fibers, separated from the o heavy tobacco fibers (ribs) and conveyed away transversely. Further sifting may then take place to recover light tobacco fibers from the weighted heavier tobacco fibers.
- the tobacco fibers contained in the shaft 228 become one
- the tobacco fibers come either in contact with the guide surface 251 or slip on a kind of air cushion consisting of the air, which is guided for example by the Blas Kunststoffdüse 307 in the device and / or slots from the Mau Kunststoff- enters the device.
- the speed of the tobacco decreases due to the increasing slope of the baffle 251.
- the baffle 251 in FIG. 5 has a relatively large negative pitch, which then merges into a substantially horizontal pitch, and then rises again. Due to the decreasing speed and the compaction of the tobacco, a web 305 is formed on the baffle 251. This becomes larger due to the decreasing o speed in the fleece height. The height and / or the
- Density of the web are measured by means of a sensor 309. This measured value can be used for control and / or control purposes. be.
- the sensors may be, for example, ultrasonic sensors or laser distance sensors.
- the tobacco mat In the region of the accelerator nozzle 303, which receives air from the air box 304, the tobacco mat is subjected to a high air velocity, so that the tobacco fibers are separated from the nonwoven occasionally. In particular, a tight-fitting wall flow is used here in particular. Subsequent to the accelerator nozzle 303, the tobacco stream 252 is divided into two tobacco streams or tobacco filling streams 256 and 25 in a deflection zone 253

- the tobacco which slides on the guide surface, is torn apart from the nozzle. The tobacco preferably slides or glides directly on the guide surface 251.
- the optimum sliding speed and thus also the density of the tobacco in front of the nozzle is adjusted by the negative pressure in the rolling space 306 enclosed by the curved guide surface 251 and the screen 271.
- a higher negative pressure means a higher air velocity in the chute and thus a lower density before the first nozzle.
- the separation becomes smaller, as a result of which the tobacco stream forming on the strand conveyor 263 and 264 becomes less uniform.
- the fleece is too thick, the singling becomes smaller again, so that an optimum can be set.
- the accumulation height or occupancy density of the tobacco in the vicinity of the nozzle 303 and / or the air pressure forming in the rolling space or in the connected expansion space is determined by means of a pressure sensor (not shown here), so as to adapt the negative pressure accordingly.

- the excess blast air of the nozzles is discharged through the screen 271 into the flash room 272, from where it is removed by the fan or other suction. The one by the
- Control be tracked depending on the engine speed.
- the height of the tobacco mat 305 is constantly monitored by a sensor 309. If the measured value is outside a tolerance range, the air conditions or pressure conditions can be adjusted by changing the setpoint for the vacuum control.
- An additional blast air nozzle 307 with associated air box 308 may be preferably connected to increase the sliding speed of the web when in certain operating conditions the risk of clogging of the shaft 228 is. This can be given in particular when starting or when shutting down the machine.
