Method and system for manufacture of multi-segment articles of tobacco industry
Method for manufacturing of multi-segment rod-like articles (25, 25, 25) of the tobacco industry in an apparatus (2) for manufacturing multi-segment rods (6) or segment rods (6, 6) comprising the steps of: feeding rod-like segments of at least one kind (A, B, C, E, F) constituting a multi-segment rod-like article (25, 25, 25); putting together rod-like segments (A, B, C, E, F) in a segments train (ST) on a wrapping material (7); manufacturing a continuous segment rod (CR, CR) or multi-segment rod (CR) containing rod-like segments (A, B, C, E, F) wrapped by the wrapping material (7), whereas the segments are pushed together or cavities are left between the segments; and cutting the continuous segment rod (CR, CR) or multi-segment rod (CR) into multi-segment rods (6) or segment rods (6, 6) containing any combination of H rod-like segments (A, B, C, E, F), double rod-like segments (A, B, C, E, F) and halves of rod-like segments (A, B, C, E, F), whereas at the time of cutting of the continuous multi-segment rod (CR) the multi-segment rods (6) or the segment rods (6, 6) move in a longitudinal direction (T1); then changing conveying direction of the multi-segment rod (6) or the segment rod (6, 6) from the longitudinal direction (T1) to a transverse direction (T2), and fixing the end segments (D) to the multi-segment rods (6) or the segment rods (6, 6), conveyed in the transverse direction (T2) in an end segment fixing apparatus (3) adapted to manufacture multi-segment rod-like articles (25, 25, 25). The method is characterised in that after the change of the conveying direction of the multi-segment rod (6) or the segment rod (6, 6) from the longitudinal direction (T1) to the transverse direction (T2), and before fixing the end segment (D), a step of checking quality the manufactured multi-segment rods (6) or the segment rods (6, 6) is performed at a measuring unit (9) and defective multi-segment rods (6) or the segment rods (6, 6) are rejected, next feeding the multi-segment rods (6) or the segment rods (6, 6) to a compensation unit (13) for storing the multi-segment rods (6) or the segment rods (6, 6) and for compensating the rejection of the multi-segment rods (6) or the segment rods (6, 6), and then feeding the multi-segment rods (6) or the segment rods (6, 6) from the compensation unit (13) to the end segment fixing apparatus (3) so that the end segment fixing apparatus (3<
TONGUE WITH PRE-FOLDING SECTION
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.
AN ARTICLE FOR AN AEROSOL PROVISION SYSTEM
An article for use as or as part of an aerosol provision system. The article may be a combustible aerosol provision system or a consumable for a non-combustible aerosol provision system. The article can include a component having an upstream end and a downstream end. The component can include a first material and a second material including an amorphous solid material. The amorphous solid material extends substantially longitudinally through the component between the upstream end and the downstream end and has a length of at least about 70% of the length of the component between the upstream and downstream ends.
