Closing device e.g. for applying screw tops to containers, has coupling which transmits torque from driver to screw top with driver having drive rotor and output rotor

摘要

The closing device (1) has a coupling (5) which transmits a torque from a driver (3) to a screw top. The driver has a drive rotor and an output rotor (21) and also a torque-transmitting device which has a magnet and hysteresis material, interacting with the magnet, or a further magnet. The closing device has a sensor (9) which detects the relative position between drive rotor and output rotor (23).
