  • the speed of the conveyor I can be varied by, changing the motor speed, while the speed of the conveyor 3 may be controlled by means of a change speed device of any suitable construction.
  • the conveyor I is moved at a greater velocity than the conveyor 3, which latter moves at the normal velocity in relation to the rate at which the tobacco feeding apparatus feeds tobaccogthat is to say, the speed at which the conveyor 3 moves is such that the quantity of tobacco fed by the tobacco feeding apparatus I6 is sufficient to provide a filler rod of the required mass.
  • the tobacco on the conveyor I is shown in the form of a stream which at substantially all points along its length is below the desired mass.
  • the velocity at whichthe conveyor I travels relatively to'the conveyor 3 and to the'rate of working of the tobacco feed governs the mass of, the tobacco on the conveyor I and it will be seen that the faster the conveyor I moves the less will be the mass of tobacco on the conveyor I. For instance, if the conveyor I is moved at asufliclently high speed, it. will be seen that the mass of tobacco received upon the conveyor I can be made very small. It will be appreciated that the velocity of the conveyors I and 3 respectively may be adjustable to any desired extent. 7
  • the tobacco shown on the conveyor I in Figure 1 is fed as a stream towards the control passage.
  • the control passage there is always a point at which thereduction in velocity of the tobacco occurs, and it can be seen that at this point the tobacco impacts against the slower moving tobacco and forms it into a filler rod.
  • the tobacco whilst in the control passage is thus packed drives the slower moving conby axial compression produced by the reduction of velocity in the passage, and the walls of the passage control the tobacco by keeping 'it within predetermined limits considered transversely of its direction of movement at or in the region of the point at which the reduction in velocity occurs.
  • the point at which the impact occurs will advance in the direction of movement of the slower moving conveyor. Conversely, if the mass of tobacco brought by the fast moving conveyor increases, the impact point willrecede, that is, movein a direction opposite that in which the slower moving conveyor is travelling, so that the packing will occur earlier. Due to this shifting of the impact point, irregularities in the tobacco fed are less in the finished filler rod when made according-to the Present invention than in a filler rod when madeby'the usual known methods, so that the present invention enables a more uniform filler rod to be formed.
