Abstract

The method for the manufacture of a susceptor sheet material comprising an aerosol-forming gel comprises the steps of providing a susceptor sheet material comprising at least one depression on both sides of the susceptor sheet material; and applying aerosol-forming gel to the at least one depression on both sides of the susceptor sheet material. Also a dosing device for the application of an aerosol-forming gel is described.

First claim

1 . Method for the manufacture of a susceptor sheet material comprising an aerosol-forming gel, the method comprising:
providing a susceptor sheet material comprising at least one depression on both sides of the susceptor sheet material; applying aerosol-forming gel to the at least one depression on both sides of the susceptor sheet material.

2 . Method according to claim 1 , further comprising applying different aerosol-forming gels to different depressions of the susceptor sheet material, wherein different aerosol-forming gels differ in at least one of flavour, nicotine, aerosol-forming agent, aerosolization temperature.

3 . Method according to claim 1 , therein applying the aerosol-forming gel via a through hole in at least one moving tooth of a gel dosing device.

4 . Method according to claim 3 , therein applying the aerosol-forming gel via the through hole in at least one moving tooth of a dosing wheel drum comprising circumferentially arranged teeth.

5 . Method according to claim 3 , therein applying the aerosol-forming gel via the through hole in at least one moving tooth of a dosing belt, and transporting the susceptor sheet material with the dosing belt.

6 . Method according to claim 1 , therein applying the aerosol-forming gel over a width of the susceptor sheet material through a plurality of through holes arranged over a width of the tooth.

7 . Method according to claim 1 , comprising:
providing a conduit with at least one gel inlet, guiding the susceptor sheet material inside and along the conduit, injecting aerosol-forming gel via the at least one gel inlet into the conduit and to the susceptor sheet material guided inside and along the conduit.

8 . Method according to claim 1 , comprising:
forming the susceptor sheet material to comprise the at least one depression by passing the susceptor sheet material through a susceptor forming device.

9 . Method according to claim 1 , further comprising passing the susceptor sheet material and a porous sheet material in parallel through a gel dosing device, thereby applying the aerosol-forming gel to the combination of susceptor sheet material and porous sheet material.

10 . Dosing system for the application of an aerosol-forming gel to a susceptor sheet material, the system comprising
a susceptor sheet material comprising at least one depression on both sides of the susceptor sheet material; a gel dosing device adapted to apply aerosol-forming gel to the at least one depression on both sides of the susceptor sheet material.

11 . Dosing system according to claim 10 , wherein the gel dosing device comprises a pair of engaging dosing wheel drums comprising circumferentially arranged teeth substantially corresponding to the form of the susceptor sheet material, wherein at least one tooth of both dosing wheel drums of the pair of dosing wheel drums comprises a through hole in fluid communication with a gel reservoir.

12 . Dosing system according to claim 10 , wherein the gel dosing device comprises a dosing belt for transporting the susceptor sheet material, and the tooth is a tooth of the dosing belt, preferably the dosing belt comprises a series of teeth substantially corresponding to the form of the susceptor sheet material, each tooth of the series of teeth comprising a through hole.

13 . Dosing system according to claim 10 , wherein the gel dosing device comprises a conduit adapted to guide the susceptor sheet material inside and along the conduit, the conduit comprising at least one gel inlet for injection of aerosol-forming gel into the conduit and to the susceptor sheet material guided inside and along the conduit.

14 . Dosing system according to claim 13 , wherein the conduit comprises two gel inlets arranged opposite each other at the conduit.

15 . Susceptor sheet material comprising aerosol-forming gel, the susceptor sheet material comprising a plurality of depressions arranged on both sides of the susceptor sheet material, wherein at least one depression of the plurality of depressions on both sides in the susceptor sheet material is filled with the aerosol-forming gel.

16 . Method according to claim 2 , comprising:
providing a conduit with at least one gel inlet, guiding the susceptor sheet material inside and along the conduit, injecting aerosol-forming gel via the at least one gel inlet into the conduit and to the susceptor sheet material guided inside and along the conduit.
