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.

18. A method for the rotational orientation of a tube head relative to a tube body comprising the steps:
-
sensing a rotated position of the tube head relative to the tube body and carrying out a relative rotation of the tube head to the tube body as a function of the sensed rotated position, wherein the sensing of the rotated position encompasses the generation of an analog or digital sensing signal corresponding to a rotary movement of the tube head or tube body, over a time sequence, which corresponds to the rotary movement, the sensing signal is correlated with a predetermined reference signal and the rotated position is determined from a characteristic value, which describes the correlation, in particular maximum correlation or minimum correlation of the correlation, characterized in that the reference signal is generated by means of a reference body, which is preferably provided in a predetermined rotated position and is stored electronically.
