- the device 9 for receiving the successive portions 7 of tobacco comprises at least one second element 12, which has a surface 12A arranged to, on the one hand, receive the tobacco crossing the free bank 11 B of the first element 11 and, on the other hand, transfer it in the form of a layer 4A, to another station 10, and this, at a determined speed, in a direction D3 substantially perpendicular to the bank 11 B, in order to the constitution of the stream 4 of tobacco fibers, each cross section of which contains the same quantity of tobacco fibers which are uniformly distributed.
- the first element 11 has an alternating movement in at least one direction D2 which is substantially parallel to the longitudinal direction D1 its receiving surface 11 A.
- the first element 11 has an alternating movement essentially in a direction D2 which is substantially parallel to the longitudinal direction D1 of its receiving surface 1 1A.
- each cross section of said layer 4A of tobacco fibers formed contains a same amount of tobacco fibers that are evenly distributed.
- the device 6 for removing, from the reservoir 3, successive portions 7 of tobacco obviously operates so as to provide the device 9 for receiving these portions, a rate of tobacco which is adjusted as a function of the rate of tobacco required at the level of a post located downstream, such as a post 10 for forming a rod 5 of tobacco.
- the transfer of the layer 4A which arises after passage of the first element 1 1 of the receiving device 9 therefore takes place at a determined speed which is adjusted as a function of the tobacco flow rate required at said station located downstream, such as the station 10 for forming a rod 5 of tobacco.
- the second element 12 consists of a belt conveyor 12B.
- the strip 12B circulates between idler rollers 12C which are, relative to a fixed support 1 B, guided in rotation and at least one of which is driven in rotation by a motor member 12D which drives the strip at a speed capable of ensuring the flow of tobacco chosen.
- the receiving surface 11A is substantially planar. As shown in the drawing, the portions 7 of tobacco taken from the tank have a certain height H.
- the receiving surface 11A has a width L which extends over a multiple of the height H of the portions.
- the first element 11 of the device 1 can perform its function of standardizing the thickness of the tobacco layer 4A which arises on the receiving surface 11 A.
- the first element 1 1 consists of a table 1 1 which, on the one hand, is, by a mechanism 14, supported and guided in translation at least in a direction D2 substantially parallel to the direction D1 in which it extends longitudinally, on the other hand, is connected to an alternative movement mechanism 15 in this direction D2.

- the mechanism 14 for supporting and guiding the table 1 1 comprises at least two rods 14A which, each located substantially at the end of the table 1 1:
- - are each, by a first end, articulated to the table 1 1 along an axis substantially orthogonal to the receiving surface 1 1A and, by a second end articulated to a fixed support 1 B, also along an axis substantially orthogonal to the surface 1 1A receiver,
- the device 1 comprises a chassis 1A and the fixed support 1 B is, for example, at least indirectly, constituted by a part of this chassis.
- the links 14A extend under the plane of the table 11.
- the reciprocating movement has an amplitude value of between two and twenty millimeters.
- the amplitude of the movement is ten millimeters.
- the reciprocating movement has a value between six hundred and two thousand cycles per minute.
- the reciprocating movement mechanism 15 comprises a motor 15A with a rotary shaft 15B which supports a crank 15C connected to a connecting rod 15D, itself at least indirectly connected to the table 11.
- the link 15D of the reciprocating movement mechanism is connected to one of the links 14A of the mechanism 14 for guiding the table 11, but it can be connected to the table.
- the alternative movement mechanism 15 has been shown in the plane of FIG. 2.
- the receiving surface 1 1A of the first element 1 1 is inclined with respect to a horizontal plane, of a value A comprised between ten degrees and forty five degrees, in such a way that the combined actions of the alternating movement and of gravity induce the transverse displacement of the tobacco towards the free bank 11 B of this surface.
- the receiving surface 11A of the first element 11 is structured so as to have increased roughness in the direction D2 of the reciprocating movement.
- the surface advantageously has grooves in a direction perpendicular to its direction D2 of alternative displacement.
- These grooves have a sufficient depth to constitute the desired roughness.
- the material which constitutes the receiving surface 1 1 B can also be chosen to exhibit these roughness features.
- the surface 12A of the second element 12 arranged to receive the tobacco from the first element 11 and to transfer it at a determined speed and in the form of a layer 4A is, in the direction of transfer, delimited by an edge 12B, beyond from which the tobacco layer 4A leaves this surface.
- the device 1 comprises a mechanism 13 which comprises: - A first rotary member 16, driven in rotation and having a plurality of fingers 16A arranged to penetrate over substantially the entire thickness of the layer 4 and accompany it in its movement towards a free bank 12E of the element 12 which supports it ,
- a second rotary member 17 which, also carrying a plurality of radial fingers 17A, is arranged and rotated at a speed such that after having penetrated into the layer 4A, said fingers 17A destructure the layer 4A of tobacco by projecting the tobacco in a plane P of orientation determined with respect to the surface 12A of the second element 12 so as to form a stream 4 of tobacco, each cross section of which contains the same quantity of tobacco fibers which are uniformly distributed.
- the first rotary member 16 of the mechanism 13 is arranged in such a way that the struts 16A which it carries, penetrate over substantially the entire thickness of the layer 4 and accompany it in its movement towards a bank 12E of the second transfer element 12 by which said layer 4 leaves its sur ace 12A.
- the plane P is advantageously approximately perpendicular to the surface 12A of the second element 12.
- the plane P is advantageously the median plane of a conduit 18 oriented to channel the fall of tobacco from the unstructured layer 4 towards a low zone of the conduit which is placed in depression, such as the entrance to a training station for a tobacco sausage 5.
- the mechanism 13 naturally includes functional elements for the support as well as the guiding in rotation and the control in rotation of its said first and second rotary members 16, 17.
- the device 1 comprises a chassis 1A and the support as well as the guide of the rotary members 16, 17 are, at least indirectly, formed by means of a part of this chassis 1A.
