ABSTRACT:
The invention refers to a centrifugal device for clamping spools on the spindles of textile machines. The clamping device substantially comprises an annular element of elastomeric material fitted on the spindle, comprising a cylindrical shank portion and an outwardly diverging conical disk portion which, when subjected to centrifugal forces created by the rotation of the spindle, will bend inwardly coming into contact and sliding with a certain amount of friction, against the internal surface of the spool, causing an axial thrust on the spool, towards a stop shoulder.
