Abstract
In a device or method for drawing a web made of a printable substrate material in a printer or copier, the web is directed in a transport gap between a drive roller and a contact pressure roller. The drive roller is driven by a motor via an electrically controllable coupling. The coupling is controlled so that the web is charged with a predetermined draw force by the drive roller. A rotation of the drive roller is detected wherein, given a set operating state with a standstill of the web, the controllable coupling is controlled depending on the detected rotation so that a draw force of the drive roller is reduced until the drive roller comes to a standstill.
