The rotator comprises a revolving plate, which is supported on bearing rollers, and a radial guide. The revolving plate forms a depositing place for a textile material holder and rotates with the holder on its longitudinal axis and is movable with the holder in the direction along the longitudinal axis. A sensor serves for measuring the movements of the revolving plate, for determining if the material holder is present and whether it is full or empty. The revolving plate has a guide element and the bottom of the container has a corresponding counterpart element. An opening in the bottom of the container and in the revolving plate makes position measurements of a spring plate carried in the material holder possible by means of a sonic measuring device.
