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

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.
A system for splicing two sheets of material containing alkaloids, the system comprising:
- a first shaft configured to hold, in a rotatable manner, a first bobbin of a first sheet of material containing alkaloids;
- a second shaft configured to hold, in a rotatable manner, a second bobbin of a second sheet of material containing alkaloids;
- one or more of the following first sheet sensors:
- a moisture sensor configured to measure a moisture of the first sheet of material containing alkaloids and to emit a signal on the basis of the moisture measurement,
- a thickness sensor configured to measure a thickness of the first sheet of material containing alkaloids and to emit a signal on the basis of the thickness measurement,
- a width sensor configured to measure a width of the first sheet of material containing alkaloids and to emit a signal on the basis of the width measurement,
- a stickiness sensor configured to measure a stickiness of the first sheet of material containing alkaloids and to emit a signal on the basis of the stickiness measurement, and
- an optical sensor or a sound sensor configured to detect a presence or absence of holes or tears in the first sheet of material containing alkaloids;
- a splicing unit configured to splice the first sheet of material containing alkaloids and the second sheet of material containing alkaloids, the splicing unit being located downstream of the one or more first sheet sensors;
- and
- a controller connected to the one or more sensors and to the splicing unit, and being configured to activate the splicing unit to splice the first sheet of material containing alkaloids and the second sheet of material containing alkaloids on the basis of the signal emitted by the one or more first sheet sensors.
