Abstract

A method for combining segments of a smoking article, comprises the steps of: —providing a group of segments having a heat source ( 10; 20 ) and an aerosol-forming substrate ( 11; 21 ) the aerosol-forming substrate ( 10; 20 ) being arranged such that a remote end ( 112; 212 ) thereof faces away from the heat source ( 10; 20 ) while a near end ( 112; 211 ) thereof abuts the heat source ( 10; 20 ), —feeding an airflow directing truncated hollow cone ( 13; 23 ) having a widest end ( 131; 231 ) and a truncated narrowest end ( 130; 230 ) such that the truncated narrowest end ( 130; 230 ) is arranged to face the remote end ( 112; 212 ) of the aerosol-forming substrate ( 11; 21 ), and —moving the truncated hollow cone ( 13; 23 ) towards the remote end ( 112; 212 ) of the aerosol-forming substrate ( 11; 21 ) to abut the remote end ( 112; 212 ) thereof or to extend into an indentation ( 113; 213 ) in the remote end ( 112; 212 ) thereof.

First claim

The invention claimed is:

1. Method for combining segments of a smoking article, the method comprising the steps of:
providing a group of segments, the group of segments comprising a heat source and an aerosol-forming substrate which are coaxially arranged in that sequence along a common central longitudinal axis, the aerosol-forming substrate being arranged such that a remote end of the aerosol-forming substrate faces away from the heat source while a near end of the aerosol-forming substrate abuts the heat source,
feeding an airflow directing truncated hollow cone having a widest end and a truncated narrowest end towards the group of segments in a manner such that the truncated narrowest end of the truncated hollow cone is arranged to face the remote end of the aerosol-forming substrate, with a central longitudinal axis of the truncated hollow cone being aligned with the common central longitudinal axis of the group of segments, and
moving the truncated hollow cone towards the remote end of the aerosol-forming substrate to abut the remote end of the aerosol-forming substrate or to extend into an indentation in the remote end of the aerosol-forming substrate.

2. Method according to claim 1 , further comprising the step of providing an air-intake tube around the truncated hollow cone, the air-intake tube having an inner diameter which essentially corresponds to an outer diameter of the widest end of the truncated hollow cone.

3. Method according to claim 2 , wherein the air-intake tube either abuts the remote end of the aerosol-forming substrate or extends over the aerosol-forming substrate, and wherein the step of moving the truncated hollow cone towards the remote end of the aerosol-forming substrate comprises pushing the truncated hollow cone through a remote end of the air-intake tube towards the remote end of the aerosol-forming substrate into a final position.

4. Method according to claim 3 , wherein in the final position the truncated narrowest end of the truncated hollow cone abuts the remote end of the aerosol-forming substrate.

5. Method according to claim 3 , wherein in the final position the truncated narrowest end of the truncated hollow cone extends into an indentation formed in the remote end of the aerosol-forming substrate.

6. Method according to claim 1 , wherein the step of moving the truncated hollow cone towards the remote end of the aerosol-forming substrate comprises providing a transfer tool having a tip, inserting the transfer tool into the truncated hollow cone to an extent that the tip of the transfer tool projects from the truncated hollow cone through the narrowest end of the truncated hollow cone, and moving the transfer tool together with the truncated hollow cone towards the remote end of the aerosol-forming substrate until the tip of the transfer tool forms the indentation in the aerosol-forming substrate and the narrowest end of the truncated hollow cone extends into the indentation formed in the aerosol-forming substrate.

7. Method according to claim 2 , further comprising the step of attaching the truncated hollow cone to the air-intake tube in an air-tight manner such that an air flow between the truncated hollow cone and the air-intake tube is prevented.

8. Method according to claim 1 , wherein the step of feeding an airflow directing truncated hollow cone towards the group of segments comprises feeding a continuous strand of truncated hollow cones, with adjacent truncated hollow cones of the strand being connected to each other, towards the group of segments and separating the foremost truncated hollow cone from the continuous strand of truncated hollow cones.

9. Method according to claim 2 , wherein the group of segments is provided as a jointly wrapped component, the jointly wrapped component comprising a wrapper extending beyond the remote end of the aerosol-forming substrate, wherein either the wrapper extending beyond the remote end of the aerosol-forming substrate forms the air-intake tube or the air-intake tube is a separate individual segment wrapped by that portion of the wrapper extending beyond the remote end of the aerosol-forming substrate, and wherein the truncated hollow cone is inserted into the air-intake tube through the remote end of the air-intake tube.

10. Method according to claim 9 , further comprising the step of transferring the jointly wrapped component comprising the group of segments together with the truncated hollow cone inserted into the air-intake tube to an assembler for assembly of the jointly wrapped component with additional components of a smoking article.

11. Method according to claim 2 , wherein the air-intake tube is an individual segment which is not connected to the other segments of the group, and wherein the truncated hollow cone is inserted into the air-intake tube through the remote end of the air-intake tube while the air-intake tube is not connected to the other segments of the group.

12. Method according to claim 1 , further comprising the step of arranging the common central longitudinal axis of the group of segments to extend perpendicular to a direction of transport of the group of segments, prior to aligning the central longitudinal axis of the truncated hollow cone to be moved towards the remote end of the aerosol-forming substrate with the common central longitudinal axis of the group of segments.

13. Method according to claim 2 , wherein the step of moving the truncated hollow cone towards the remote end of the aerosol-forming substrate comprises providing a transfer tool having a tip, inserting the transfer tool into the truncated hollow cone to an extent that the tip of the transfer tool projects from the truncated hollow cone through the narrowest end of the truncated hollow cone, and moving the transfer tool together with the truncated hollow cone towards the remote end of the aerosol-forming substrate until the tip of the transfer tool forms the indentation in the aerosol-forming substrate and the narrowest end of the truncated hollow cone extends into the indentation formed in the aerosol-forming substrate.

14. Method according to claim 4 , wherein the step of moving the truncated hollow cone towards the remote end of the aerosol-forming substrate comprises providing a transfer tool having a tip, inserting the transfer tool into the truncated hollow cone to an extent that the tip of the transfer tool projects from the truncated hollow cone through the narrowest end of the truncated hollow cone, and moving the transfer tool together with the truncated hollow cone towards the remote end of the aerosol-forming substrate until the tip of the transfer tool forms the indentation in the aerosol-forming substrate and the narrowest end of the truncated hollow cone extends into the indentation formed in the aerosol-forming substrate.

15. Method according to claim 4 , wherein the step of feeding an airflow directing truncated hollow cone towards the group of segments comprises feeding a continuous strand of truncated hollow cones, with adjacent truncated hollow cones of the strand being connected to each other, towards the group of segments and separating the foremost truncated hollow cone from the continuous strand of truncated hollow cones.

16. Method according to claim 4 , wherein the group of segments is provided as a jointly wrapped component, the jointly wrapped component comprising a wrapper extending beyond the remote end of the aerosol-forming substrate, wherein either the wrapper extending beyond the remote end of the aerosol-forming substrate forms the air-intake tube or the air-intake tube is a separate individual segm
