Abstract

The invention relates to a method for manufacturing multi-component aerosol forming articles, each aerosol forming article defining a longitudinal axis and comprising N components serially juxtaposed along the longitudinal axis, where N is an integer≥2, the method comprising: —providing transporting means for transporting components of aerosol forming articles in a transporting direction, said transporting means defining seats along said transporting direction; —supplying seats of said transporting means with a first component for each aerosol forming article by positioning said first components one after the other along the transporting direction with their longitudinal axis parallel one to the others; —checking each seat for the presence of said first component; —adjoining a second component to the first component in a lengthwise axial manner in a given seat only if the first component is present in said given seat.

First claim

The invention claimed is:

1. A method for manufacturing multi-component aerosol forming articles, each aerosol forming article defining an aerosol longitudinal axis and comprising N components serially juxtaposed along the aerosol longitudinal axis, where N is an integer≥2 and each component comprising a component longitudinal axis, the method comprising:
providing transporting seats for transporting components of aerosol forming articles in a transporting direction, said transporting seats defining seats along said transporting direction;
supplying seats of said transporting seats with a first component for each aerosol forming article by positioning said first components one after the other along the transporting direction with their component longitudinal axis parallel one to the others;
checking each seat for the presence of said first component;
adjoining a second component to the first component in a lengthwise axial manner in a given seat only if the first component is present in said given seat.

2. The method according to claim 1 , comprising:
checking each seat for the presence of said second component;
adjoining a third component to the second component in a lengthwise axial manner in a given seat only if the first component and the second component are present in said given seat.

3. The method according to claim 1 , comprising:
checking each seat for the presence of a (N−1)th component;
adjoining a Nth component to the (N−1)th component in a lengthwise axial manner in a given seat only if all components from the first component to the (N−1)th component are present in said given seat.

4. The method according to claim 3 , comprising:
recovering the Nth component from a given seat if any of the components from the first component to the (N−1)th component is missing from said given seat.

5. The method according to claim 1 , wherein said Nth component comprises tobacco.

6. The method according to claim 1 , wherein said first component is a segment of a filter of an aerosol forming article.

7. The method according to claim 1 , comprising:
adding a second component to each axial side of the first component and adjoining a Nth component to each (N−1)th component to both sides of each first component in a lengthwise axial manner in a given seat only if all components from the first component to each (N−1)th component are present in said given seat.

8. The method according to claim 1 , wherein said first component is a double length first component.

9. The method according to claim 1 , comprising:
adjoining 2N−1 components in a lengthwise axial manner in each seat.

10. The method according to claim 1 , comprising:
compressing all components along the aerosol longitudinal axis present in each seat.

11. The method according to claim 1 , comprising:
wrapping at least some of said components with paper.

12. The method according to claim 1 , comprising:
cutting said first component in two.

13. The method according to claim 1 , wherein the seats are equally spaced.
