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.

A machine for making a continuous tubular element with filling from web material, including first and second means for feeding respective continuous webs, a forming station configured to perform a folding and/or deformation of a first continuous web in a shaped configuration, and a wrapping station wherein the second continuous web is wound in a tubular shape around the first continuous shaped web to obtain the continuous tubular element. Upstream of the wrapping station there is a first gluing device configured to apply at least one longitudinal line of glue on at least one of the continuous webs in such a way as to define at least one gluing zone, said longitudinal line of glue being positioned in such a way as to coincide with a zone of superposing and contact between the two continuous webs feeding out of the wrapping station.

A method for producing a rod containing herbaceous material comprises the steps of: providing a sheet material containing herbaceous material; shaping the sheet material into a rod-shape by conveying the sheet material along a conveying direction through a funnel-shaped converging device; and dispensing an additive onto the sheet material within the converging device.

A mold for producing an aerosol-generating article includes a first main body, a second main body and a third main body arranged in sequence in a first direction, wherein an extrusion channel extending in the first direction is formed in the third main body; a first stand column and a feeding channel is provided on the second main body, the feeding channel extends in the first direction and is in communication with the extrusion channel, and the first stand column extends to the extrusion channel in the first direction; and a second stand column and a first cavity is provided on the first main body, the first cavity extends through two opposite ends of the first main body in the first direction and is in communication with the feeding channel, and the second stand column extends to the extrusion channel in the first direction.
