text: This way an even more homogeneous sheet of alkaloids containing material may be realised by means of the influence of gravity.
text: Using this design, the width of the aperture and therefore the thickness of the cast sheet of alkaloids containing material may be set very precisely.
text: This way a particularly homogeneous thickness of the cast sheet of alkaloids containing material may be realised.
text: This drying may be performed while the slurry/the cast sheet of alkaloids containing material still rests on the conveyor belt, which may act as a supporting support.
text: This way the produced sheet of alkaloids containing material may be stored before it is actually needed.
text: Furthermore, the sheet of alkaloids containing material may be easily transported to another production machine or even another production facility if it is rolled into a bobbin.
text: The thus produced sheet of alkaloids containing material may be used for an aerosol-forming substrate that may be used later on for use in an aerosol generating device.
text: The aerosol-forming substrate may be a solid aerosol-forming substrate that may be based on a sheet of alkaloids containing material.
text: Alternatively, the aerosol-forming substrate may comprise both solid and liquid components, where at least part of the solid components may be based on a sheet of alkaloids containing material.
text: The aerosol-forming substrate may be formed from or may comprise a alkaloids containing material having an aerosol former content of greater than about 5 percent on a dry weight basis and water.
text: The alkaloids containing material may be based on a cast sheet of alkaloids containing material.
text: The alkaloids containing material may be based on a cast sheet of alkaloids containing material.
text: For example, the alkaloid containing material may have an aerosol former content of between about 5 percent and about 30 percent by weight on a dry weight basis.
text: 1 shows the basic principle of how to cast a sheet of alkaloids containing material according to the state of the art in a schematic perspective view; FIG.
text: 2 is a first embodiment of how to produce a cast sheet of alkaloids containing material with homogeneous thickness in a schematic view from the side; FIG.

text: 4 is a third embodiment of how to produce a cast sheet of alkaloids containing material in a schematic view from the side.
text: 1 a casting apparatus 1 for casting sheets 2 of alkaloids containing material from a slurry 5 as presently used in the state of the art is shown in a partial, schematic perspective view.
text: Using the casting apparatus 1, a thin sheet 2 of alkaloids containing material is cast on the flexible, thin movable metal support 3 that is presently made out of a thin band of steel.
text: It is noted that in FIG. 1 only a part of the complete casting apparatus 1 is shown, namely the part where the casting of the sheet 2 of alkaloids containing material is done.
text: The conveyor belt 3 may show a significant length so that the sheet 2 of alkaloids containing material that is initially present on conveyor belt 3 in a viscous or pasty form has sufficient time to dry so that it can become mechanically stable and can be pulled off the conveyor belt 3.
text: When being pulled off the conveyor belt 3, the sheet 2 of alkaloids containing material has to be mechanically self-sustaining.
text: The thus created sheet 2 of alkaloids containing material can be wound up onto a bobbin that can be easily stored or that can be transported to other production machine or even another production facility.
text: 1 , only the left roller 4 is visible, where roller 4 is an actively driven roller, so that roller 4 is able to move the conveyor belt 3 together with the deposited sheet 2 of alkaloids containing material on top.
text: Furthermore, it is possible to provide the casting apparatus 1 with heating devices (not shown) so that the cast sheet 2 of alkaloids containing material dries faster.
text: This can be done by electrical heating elements or some gas flames that heat up appropriate areas of the conveyor belt 3 and therefore the sheet 2 of alkaloids containing material that is cast on top of the conveyor belt 3.
text: The cast sheet 2 of alkaloids containing material is produced out of a slurry 5 that is a viscous or pasty mixture of particles, essentially made of finely ground tobacco material, where the particles are brought into a viscous or pasty form by mixing it with a solvent.
text: The aperture is of a rectangular shape and determines the cross-sectional shape of the sheet 2 of alkaloids containing material.
text: Also, the thickness of the sheet 2 of alkaloids containing material is determined by the height of the aperture that is formed by the casting blade 9 and the conveyor belt 3.
text: This relates to the “initial” thickness of the sheet 2 of alkaloids containing material, since the thickness may change due to a drying process.
text: Typically, a shrinkage of the sheet 2 of alkaloids containing material occurs, for example during drying.
text: A size of the aperture formed by the cutting edge 13 of the casting blade 9 and the upper surface of the conveyor belt 3 has to remain constant to obtain a sheet 2 of alkaloids containing material with constant thickness.
text: On the contrary, some dirt that is present on the roller 4 (or on the lower side of the conveyor belt 3) may lead to a small bump, decreasing the thickness of the sheet 2 of alkaloids containing material.
text: Then, the fixed height of the casting blade 9 will mean that the size of the aperture will vary, and consequently, the thickness of the cast sheet 2 of alkaloids containing material will not be homogeneous.
text: Therefore, in FIG. 2 a method for producing a cast sheet 2 of alkaloids containing material is proposed which will be further explained with reference to FIG.
text: For the sake of clarity, the slurry 5 and the cast sheet 2 of alkaloids containing material are not shown in FIG.
