Abstract (en)
[origin: WO2020177910A1] The invention relates to a method and a device for winding a material web (1) onto a winding tube (2) to form a wound roll (3) in roll slitting machines after the longitudinal cutting of a material web (1), which is unwound from a parent roll (4), the parent roll (4) and the wound roll (3) being driven and the web tension between the parent roll (4) and the wound roll (3) being measured. The invention aims to improve the winding result in roll slitting machines by virtue of the fact that, in accordance with the operating state, the driving (8) of the parent roll (4) or the driving (9, 10) of the wound roll (3) is carried out in such a way that the web tensile stress lies in a specified interval.
