The method for manufacturing an inductively heatable aerosol-forming substrate comprises the steps of providing a tobacco containing slurry, providing an inductively heatable continuous sheet-like material and joining the tobacco containing slurry and the inductively heatable continuous sheet-like material to form an inductively heatable aerosol-forming substrate. A further step comprises drying the inductively heatable aerosol-forming substrate while transporting the inductively heatable aerosol-forming substrate on a conveyor device.

Method for manufacturing an inductively heatable aerosol-forming substrate

The invention relates to a method for producing a bobbin and a bobbin. The bobbin includes a plurality of windings of a continuous laminated sheet having at least one layer of alkaloids containing material and at least one layer of a first protective material. The at least one layer of alkaloids containing material and the at least one layer of a first protective material define an adhesion surface between them. The first protective material is selected from polypropylene, polyethylene, polytetrafluoroethylene, polyester, or paper.
