A method of forming a wrapped article, comprising the steps of: forming a continuous stream of material such as an agricultural product; moving the continuous stream of material along an elongated path; compressing the continuous stream of material to reduce the cross-sectional area thereof until a predetermined cross-sectional dimension is achieved; drawing the compressed continuous stream of material through a rod-forming arrangement, the rod-forming arrangement having a non-contact displacement transducer associated therewith; folding at least one web longitudinally around the compressed continuous stream of material to form a continuous rod of material; and detecting variations in rod density within the rod-forming arrangement from a signal obtained from the non-contact displacement transducer.

A spacing drum comprising: a segment receiving drum section capable of receiving a predetermined number of segments per revolution of the drum from a procession of segments approaching the segment receiving drum section at a segment-feed spacing and a segment-feed speed; a segment releasing drum section capable of releasing the predetermined number of segments at a segment-release spacing and a segment-release speed; and a radial profile flight comprising a continuous arc segment extending across at least portions of the segment receiving drum section and the segment releasing drum section. Associated methods are also provided, including method of changing pitch along a spacing drum progressively with a radial profile flight.

A machine for wrapping smokable material in a wrapper includes a garniture defining a straight path along a longitudinal axis on which a wrapper is guided. A garniture belt transports the wrapper along the straight path. A feeding device for feeding a smokable material to the garniture includes a first conveyor having an upper section on which the smokable material is supported, the first conveyor being actuatable to move the smokable material in a feed direction toward a downstream side of the first conveyor. A holding container has a bottom defined at least partially by the first conveyor. A feed transports the smokable material from a supply container to the holding container so that that an amount of smokable material in the holding container is maintained within a range including a predetermined minimum amount and a predetermined maximum amount. A metering device meters the amount of smokable material that is moved by the first conveyor from the holding container toward the garniture.
