ABSTRACT:
The expanding device for supporting emery cloth sleeves in particular, includes a shaped shaft which concentrically supports a plurality of mutually facing disks which can slide in an axial direction and which are rigidly rotationally connected with the shaft. The disks define, between one another in cooperation, a plurality of peripheral seats for the accommodation of elastic rings which can expand radially upon the axial compression of the disks. The elastic rings are suitable for engaging the inner surface of an emery cloth sleeve.
