  • the method comprises the step of detecting the presence and/or the size of bubbles inside the fluid before supplying said strip 5 of fluid on the band 4 of wrapping material and/or the rope 2 of a material from the tobacco industry.
  • the method comprises the steps of:
  • the machine 100 is stopped in a controlled manner, the supply nozzle 11 is cleaned and then the machine 100 is restarted (with manual or automatic restart). It is understood that, as known to one skilled in the art, restarting of a machine 100 following a controlled stop is less time consuming and simpler than a restart following an undesired stop of the machine 100.
  • said first embodiment of the method is particularly advantageous in the case in which the size of the bubble is greater than a threshold value (in other words, in the case in which the bubble is "large”): in fact, larger dimensions of the bubble with respect to said threshold value would cause the formation of a discontinuity such as to cause the undesired stop of the machine.
  • the step of cleaning the nozzle 11 involves discarding the fluid from the nozzle 11 in order to release the detected bubble.
  • the method comprises the step of decreasing the speed of the machine 100 for forming the rod 1 of the tobacco industry in the case the presence of at least one bubble is detected inside the fluid and the size of said bubble is smaller than a predetermined threshold value.
  • speed of the machine 100 we mean the length of a rod 1 produced per time unit.
  • the fact of decreasing the speed of the machine 100 is particularly advantageous in the case in which the size of the bubble is smaller than the threshold value (in other words, in the case in which the bubble is "small"): in fact, the bubble having smaller dimensions than said threshold value would cause the formation of a discontinuity in which there would be no undesired stop of the machine but only the production of articles to be discarded (which can possibly be subsequently checked).
  • the method comprises the step of emitting an alarm signal (for example, an optical and/or sound signal) in the case the presence of at least one bubble is detected inside the fluid and/or the size of said bubble is greater than a predetermined threshold value.
  • an alarm signal for example, an optical and/or sound signal
  • the method can comprise the step of detecting the flow rate of the fluid inside the conduit 12. Furthermore, the method comprises the step of controlling the pump 16, on the basis of the detected flow rate, so that the flow rate of the fluid is equal to a value of a predetermined flow rate or is kept within a range of predetermined flow rate values.
  • a further embodiment of the method comprises, if the presence of at least one bubble is detected inside the fluid and/or the size of said bubble is greater than a predetermined threshold value, the step of allowing the bubble come out from the fluid through the second portion 12b of the conduit 12.
  • This last step comprises the sub-step of opening the valve, allowing the bubble to come out from the fluid through the second portion 12b of the conduit 12 and reclosing the valve.
  • the proposed method and machine allow to avoid the unexpected stop of the machine 100 due to the presence of bubbles in the fluid (in particular glue or flavouring agent) or by means of a controlled stop of the machine 100 (which controlled stop allows a restart, automatic or manual, simpler than an unexpected stop due for example to the breaking of the rod) or by reducing the speed of the machine 100.
  • the controlled stop of the machine 100 is preferred in the case in which the detected bubble has a larger size than a predetermined threshold value and in the case in which it is not desired to produce products that may be discarded.
  • the decrease in the speed of the machine 100 is preferred in the case in which the detected bubble has a smaller size than a predetermined threshold value (in this case there is no undesired stop of the machine but only products possibly to be discarded).
