Abstract: A method for manufacturing a rod-shaped aerosol-generating article is provided, including: arranging segments in a row along a longitudinal direction; wrapping a first sheet around at least one of the segments; and wrapping a second sheet around at least one of the segments so as to at least partially overlap the first sheet, such that upon wrapping the second sheet, an electromagnetic information marker is created, the electromagnetic information marker including a first structure provided on the first sheet and a second structure provided on the second sheet. A rod-shaped aerosol-generating article, an aerosol-generating system, and a sheet, are also provided.

Abstract: An aerosol-generating device is provided, including: a device housing defining a cavity; an adjustable retaining element positioned in or adjacent to the cavity and defining a passage; and an actuator configured to actuate the element between receiving and retaining positions, in which a cross-sectional dimension of the passage is greater when the element is in the receiving position than when in the retaining position, the element defining a passage entrance and a passage exit and includes a surface defined between the entrance and the exit, a longitudinal cross-section of the surface having a curved shape when the element is in the retaining position, a portion of the curved shape including a convex curve defining a constriction in the passage at a turning point of the curve, and the element being compressed in a longitudinal direction when the element is actuated from the receiving position to the retaining position.

Abstract: The apparatus for the extraction of ingredients from plant material, in particular alkaloids or tobacco flavors from tobacco material comprises a first screw conveyor (1, 22) with at least one rotatably driven first screw (8, 25, 26), which is adapted to convey the plant material from a first screw conveyor inlet (3, 37) to a first screw conveyor outlet (4). The apparatus further comprises a second screw conveyor (9, 23) with at least one rotatably driven second screw (9, 27, 28), which is adapted to convey the plant material from a second screw conveyor inlet (6) to a second screw conveyor outlet (7). A fluid connection (5, 38) is provided in between the first screw conveyor outlet (4) and the second screw conveyor inlet (6). The fluid connection is adapted to enable flow of plant material from the first screw conveyor outlet to the second screw conveyor inlet. The first screw conveyor has a first fluid outlet at its downstream side. The second screw conveyor has a second fluid outlet at its downstream side.

Abstract: The invention relates to a method for optical analysis of a component of an aerosol generating article, the method comprising:—providing a component of an aerosol generating article defining a first end and a second end, the component comprising: o an aerosol forming substrate; o a susceptor in thermal contact with the aerosol forming substrate;—providing a first polarized camera including a sensor to detect polarization information of electromagnetic radiation;—illuminating the component by electromagnetic radiation;—detecting transmitted, infected or refracted electromagnetic radiation from the component by the first polarized camera; —generating a first image of the first end of the component by the first polarized camera, the first image being formed by a plurality of pixels, each pixel of the plurality of pixels containing polarization information about the detected electromagnetic radiation; and—detecting in the first image a position of the susceptor.

Abstract: The invention relates to an aerosol-generating device. The device may comprise a main body (10) that may comprise a connection portion (16). The device may further comprise a removable mouthpiece (12) that may comprise a first connection element (14). The first connection element may be configured removably engageable with the connection portion of the main body. The first connection element may be configured to irreversibly change upon disengagement of the first connection element from the connection portion of the main body.
