Antriobo device for TonoufzeiohntingD- and / or playback devices

Kd are already left-hand and right-hand drive devices Known for Magnetongorätö, in which the winding plate on the one hand rubbing open over a Roibungokuppluna during normal operation (Sound recording or playback) and, on the other hand, rigidly coupled to the drive in the event of a rapid advance will. Serve the production of the individual botry-tlebs zuatonde z. B. electromagnetically 'uisste-operable clutches, which either when idling without touching the two cupola shafts or at Normal operation (recording and playback) as slip clutches work or at high speed a rigid coupling of the Wikkeltollor enable with the drive.
