Shredded tobacco is fed into and transported through a cigarette maker by a unit that includes at least one transport roller, driven in rotation about a longitudinal axis and equipped with a plurality of radial pins projecting radially from a peripheral surface, by which the flow of tobacco is taken up and directed along a predetermined feed path toward a unit that forms it ultimately into at least one continuous stream; the feed and transport unit is also equipped with at least one sensing device, offered to the peripheral surface of the roller and serving to detect any points where pins may be missing or damaged.
