A method for manufacturing rod-like articles for tobacco industry, the rod-like articles comprising longitudinal inserts located in a filling material, the method comprising: feeding a continuous tape-like wrapper; feeding a strand of the filling material onto the moving wrapper; feeding an insert material, in a form of a tape having weakenings, into the strand of the filling material; forming a continuous rod by wrapping the wrapper around the strand of the filling material with the insert material; cutting the moving continuous rod into discrete rod-like articles by a cutting head at a cutting plane that traverses the weakening in the tape of the insert material; the method being characterized by: inspecting ends of the insert in the rod like article cut from the continuous rod and comparing the ends with a predefined model to obtain a measure of similarity; and depending on the similarity, adjusting the action of the cutting head with respect to the movement of the continuous rod such as to increase the similarity between the ends of the insert to the model in a following rod like article.

The tongue includes a shaft, the shaft being hollow. The tongue includes an upper plate connected to the shaft. The upper plate includes a first protrusion on a first side of the upper plate, and a second protrusion on the first side of the upper plate. The first protrusion and the second protrusion define a notch. The first protrusion runs along at least part of an upper portion of a longitudinal length of the shaft. The rod forming apparatus includes the tongue. The method installs the tongue on the rod forming apparatus.

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.

An apparatus arranged to form a continuous tobacco rod of a smoking article, comprises a conveyor conveying a tobacco material stream in a conveyance direction, and a wrapping material supply arrangement advancing a web of wrapping material in the conveyance direction adjacent to the tobacco material stream. A constriction member receives the tobacco material stream at an inlet end and reduces a cross-sectional area of the tobacco material stream. The reduced-area tobacco material stream exits the constriction member at an exit end, and the wrapping material web wraps about the reduced-area tobacco material stream exiting the exit end. An additive source supplies an additive material to the reduced-area tobacco material stream through a dispensing port disposed about the exit end of the constriction member, prior to the reduced-area tobacco material stream being wrapped by the wrapping material web to form the continuous tobacco rod.

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 device (1) for producing an aerosol-generating rod (3) comprises a converging device (5), a susceptor guide (19), and a conveyor system. The converging device has a forming space converging along an axial direction (17). The susceptor guide extends into the forming space of the converging device and comprises an exit opening (21) for a susceptor (23) within the forming space (9) of the converging device. The conveyor system is configured to convey filling material (15), preferably formed as a sheet, through the forming space of the converging device to shape the filling material into a rod incorporating the susceptor. The device further comprises at least one additive supply line (29) having a dispensing opening that opens into the forming space of the converging device radially outward of the susceptor guide.

An example embodiment includes a tongue includes a forming surface of a forming channel, the forming channel configured to enable the shaping of shredded material into a desired form as a shredded material is drawn through the forming channel and an arrangement to introduce at least a portion of a web component adjacent a portion of the forming surface such that the introduced web component portion may be operative upon the drawn shredded material as a source of additional drawing action. The tongue may include an arrangement to draw a moving web into the tongue through a channel that converges with the working surface of the tongue, whereby the moving web is interposable between a moving column of shredded material and the first surface portion of the working surface to reduce friction. The tongue may further comprise an arrangement comprising a scalloped surface portion along the working surface of the tongue.

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 device (1) for producing an aerosol-generating rod (2) includes a converging device (3), a conveyor system (13), a susceptor guide (15), and an additive dispensing pipe (21). The conveyor system is configured to convey sheet material (11) through the converging device. The susceptor guide is configured to guide a susceptor (9). The susceptor guide extends into the converging device along an axial direction and comprises an exit opening (19) for the susceptor within the converging device. The additive dispensing pipe has an end section (29) extending within the converging device in parallel with the susceptor guide. The end section comprises a dispensing opening (31) to dispense an additive through the dispensing opening.

A method for producing a rod (3) containing herbaceous material comprises the steps of: providing a sheet material (5) containing herbaceous material; shaping the sheet material into a rod-shape by conveying the sheet material along a conveying direction (7) through a funnel-shaped converging device (13); and dispensing an additive (21) onto the sheet material within the converging device.
