Machine and method for producing substantially cylindrical articles of the tobacco processing industry; a material with cavities is fed, along a given path, through an insertion station, where powder material is inserted into the cavities, so as to obtain a strand, and through a wrapping station, in the area of which a strip is wrapped around the strand; the powder material is inserted into each cavity by a relative insertion unit, which moves in a synchronous manner along a coupling portion of the given path. 123345. A method for producing a rod () for substantially cylindrical articles () of the tobacco processing industry; each article () comprising portions ( , ) of different materials; the method comprising:{'b': 7', '1', '8', '9', '7', '12, 'a feeding step, during which a first material () is fed, in a conveying direction (A) along a first given path (P), through an insertion station () and to a wrapping station (); the first material () having cavities () arranged in succession in the conveying direction (A);'}{'b': 11', '12', '8', '13, 'an insertion step, during which a given amount of a loose material (), in particular in the form of particles and/or fibres and/or granules, is inserted into the cavities () in the insertion station (), so as to form a strand (); and'}{'b': 15', '13', '13', '9, 'a wrapping and stabilizing step, during which a strip () is wrapped around the strand () and stabilized around the strand () itself in the wrapping station ();'}{'b': 16', '17', '18', '11', '17', '7', '16', '12, 'the method being characterized in that an insertion unit (), which comprises a loading chamber () to hold the given amount of loose material and an unloading device () to unload the loose material () from the loading chamber (), is moved into the area of the first material (), so that the unloading device () faces one of the cavities ();'}{'b': 16', '1', '18', '12', '11', '16', '12, 'during the insertion step and the feeding step, the insertion unit () is ...
