ABSTRACT:
Process and device to spool longitudinally cut partial sheets from a material sheet having a sheet width. The process may include forming a spooling roll from each partial sheet such that the formed spooling rolls rest on at least two spooling beds including individually motorized spooling-support rolls. During at least a beginning of the spooling process, the process also may include pressing at least one of the spooling rolls being formed against its respective spooling bed with a loading roll, positioning the at least one spooling roll with the loading roll in a middle portion of sheet width, and motorizing the loading roll independently of the support rolls to initiate an adjustable portion of a turning moment exerted onto the at least one spooling roll. The device may include two spooling bed tracks composed of spooling support rolls to receive spooling rolls to be formed from the longitudinally cut partial sheets, at least one loading roll that is adjustably positionable onto one of the spooling rolls, and an individually controllable motor associated with each spooling support roll and with the at least one loading roll. The one of the spooling rolls may be formed in a middle portion of the sheet width.
