ABSTRACT:
A feed roll for transporting a material web and measuring a web tension of the material web which is continually moved in a roller rotary printing machine. The feed roll is rotationally supported at both sides in two levers which are pivotably arranged in the frame of the machine. A force acting on the axis of the feed roll and proportional to a web tension is measured by a measure value-receiver which detects a path of movement of a translating lever rigidly connected to at least one of the pivotable levers.
