ABSTRACT:
For the continuous measurement of the thrust forces produced by the spinning rolls on the workpiece to be extended while the spinning rolls are rotating a measuring rod is provided, which has its one end fixed coaxially on the spindle within a hollow spindle, while its other end projects freely out of the spindle. In the plane of the free end of the measuring rod a distance sensor is arranged, which detects the radial displacement, caused by the radial flexure motion of the spindle, of the measuring rod and computes the force acting on the spinning roll using a processing unit.
