The DHS non-contact loop control for detecting thin materials when winding and unwinding endless strips. With the loop control, stamped strips with a thickness of 0.2 mm or more can be wound or unwound from a reel evenly and without jerks, and thus also without tension and stress. The loop control regulates the drive of the winder in such a way that continuous and vibration-free operation is ensured as a function of the decreasing or increasing diameter of the coils. Eight or 16 infrared light beams are arranged horizontally as through-beam sensors in such a way that only one light beam at a time passes through the material loop of the strip. Trembling movements of the belt do not influence the function. Each light beam can be assigned an output value between 0 and 10 VDC by programming adapter, which is provided at the output as a setpoint for the drive (frequency converter) until another light beam is passed by the belt loop. This ensures continuous operation of the winder drive.
