Abstract (en)

[origin: EP2065324A2] The method involves subdividing continuous material e.g. paper (101), into two web-tension sections and limiting one of the sections by two clamping points (110-115). Web tension in the sections is adjusted via angular displacement, rate feedback and/or limitation of a driving torque of one of the points that limits the sections when the material is in standstill condition. The web tension in the sections is ascertained using measuring elements via driving torque of one of the points that limits the sections via operators. The material is clamped between points. Independent claims are also included for the following: (1) a computer program with program code unit for carrying out a method for adjusting web tension of a processing machine (2) a computer program product with a program code unit stored on a computer-readable data storage device for carrying out a method for adjusting web tension of a processing machine.
