1. Casting apparatus for the production of a cast web of a material containing alkaloids, the casting apparatus comprising:
a casting box having casting box walls including a first and a second opposite walls, and adapted to contain a slurry;
a movable support;
a casting blade adapted to cast the slurry contained in the casting box onto the movable support so as to form the cast web of said material containing alkaloids; and
a bar-like element located inside the casting box and configured to be completely submerged in the slurry, the bar-like element being positioned at a first and at a second distance from the first and the second opposite walls, respectively, so that the slurry can flow around the bar-like element,
wherein the movable support is adapted to move along a casting direction and wherein the bar-like element is positioned perpendicular to the casting direction,
wherein the casting box has a given casting box height, and the bar-like element is positioned in the casting box at a height which is half of the casting box height.
