(57) Abstract of the Disclosure: Method and device in the press section of a paper machine, in particular in a so-called closed press section provided with a smooth-faced press roll (10), for the control of the detaching of the paper web from the said press roll (10). In the method and by means of the device, the temperature of the face (10') of the said smooth-faced press roll (10) is adjusted. By means of this adjusting, the adhesion between the roll face (10') and the paper web (W) to be detached is affected, and thereby the detaching angle (0) and/or the detaching tension (T) of the paper web is set within an optimal range. The temperature profile of the smooth-faced press roll (10) in the axial direction of the roll (10) can also be adjusted in view of controlling the detaching process.
