1. A method for splicing two sheets of material containing alkaloids, the method comprising:
providing a first sheet of material containing alkaloids wound in a first bobbin;
providing a second sheet of material containing alkaloids wound in a second bobbin;
unwinding the first sheet of material containing alkaloids wound in the first bobbin;
evaluating one or more of the following parameters of the unwound first sheet of material containing alkaloids:
moisture of the first sheet of material containing alkaloids,
thickness of the first sheet of material containing alkaloids,
width of the first sheet of material containing alkaloids,
stickiness of the first sheet of material containing alkaloids, and
presence or absence of holes or tears in the first sheet of material containing alkaloids; and
depending on a value of the evaluated one or more parameters, unwinding the second sheet of material containing alkaloids wound in the second bobbin, and splicing the first sheet of material containing alkaloids and the second sheet of material containing alkaloids.
