Abstract (en)
[origin: WO2019076497A1] The invention relates to a method for unwinding a material web (1), in particular a paper or board web, for a subsequent machine unit (9) for processing the material web (1), with an unwinding station, which comprises a primary unwinding device (2), at least one secondary unwinding device (3) and at least one adhesion-cutting device (5, 6), wherein the wound roll (7) is unwound first in the primary unwinding device (2) and, after being transferred, is unwound further in a secondary unwinding device (3), and a new wound roll (7) is inserted into the primary unwinding device (2) and, in the event of a roll change, the adhesion-cutting device (5, 6) joins the material web (1) of the secondary unwinding device (3) to the material web (1) of the new wound roll (7) and cuts through the material web (1) running from the secondary unwinding device (3) to the adhesion point. In addition, possible applications and operating safety are to be increased with minimum expenditure in that the single secondary unwinding device (3) is arranged between the primary unwinding device (2) and the subsequent machine unit (9), and multiple adhesion-cutting devices (5, 6) enable optionally different splicing methods for connecting the end of the material wed (1) running off the secondary unwinding device (3) with the start of the web of the new wound roll (7) of the primary unwinding device (2).
