Abstract
A device for the automatic rotational orientation of a tube head (16) relative to a preferably stationary tube body (14), wherein the device has a sensor (18) for sensing a current rotated position of the tube head or tube body having a position indicator (21), the device further includes a positioning device (12, 20) which interacts with the sensor and is designed to effect a rotary movement of the tube head or of the tube body in reaction to a control signal from a control unit (22). The sensor is designed to generate a sensing signal corresponding to a rotary moment of the tube head or tube body and the control unit correlates the sensing signal with a reference signal and for generating a control signal from a characteristic value corresponding to a degree of correlation, in particular a maximum correlation or minimum correlation, for the positioning device.
