Abstract

The invention relates to an apparatus ( 1 ) for the production of a rod component ( 100 ) of an aerosol generating article, said apparatus comprising: ∘ a first mover ( 4 ) adapted to transport a first sheet ( 2 ) along a first direction; ∘ a second mover ( 5 ) adapted to transport a second sheet ( 3 ) along a second direction; ∘ a third mover ( 6 ) adapted to transport a susceptor strip ( 10 ) along a third direction, said third mover being adapted to position said susceptor strip between the first and the second sheet during transport; and a rod forming device ( 20 ) being adapted to form a rod from the first and the second sheets and the susceptor strip and having an inlet ( 21 ) and an outlet ( 22 ), wherein said first and second sheets and said susceptor strip are introduced in said inlet and said rod is outputted from said outlet.

First claim

The invention claimed is:

1. A method for the production of a component of an aerosol generating article, said method including:
providing a first sheet;
providing a second sheet;
providing a strip of susceptor;
transporting the first and second sheets and the strip of susceptor along a first, second and third direction, respectively, keeping the strip of susceptor located between the first and the second sheets during the transport; and
forming a rod gathering together the first and the second sheets and the strip of susceptor located therebetween.

2. The method according to claim 1 , wherein the step of moving the first sheet, the second sheet and the strip of susceptor along the first, second and third direction includes moving the first sheet, the second sheet and the strip of susceptor so that the first, second and third direction are coplanar.

3. The method according to claim 1 , including:
coating the first or second sheet or the strip of susceptor with a water-based solution.

4. The method according to claim 1 , wherein the step of providing the strip of susceptor includes:
providing a continuous strip of susceptor;
cutting the continuous strip of susceptor in susceptor segments; and
transporting the susceptor segments between the first and second sheet.

5. The method according to claim 4 , wherein the component of the aerosol generating article has a pre-determined length, and the step of cutting the continuous strip of susceptor in susceptor segments includes cutting the continuous strip of susceptor in susceptor segments having a length equal to or smaller than the pre-determined length of the component.

6. The method according to claim 3 , including:
cutting the rod into components of the aerosol forming article.

7. The method according to claim 6 , including:
synchronizing the cutting of the rod into components with a speed of the transport of the first sheet, or of the second sheet or of the strip of susceptor along the first, second or third direction, respectively.

8. The method according to claim 6 including:
sensing the presence of a susceptor segment in the rod before cutting the rod.
