Abstract
An electromechanical friction clutch and brake unit is disclosed for actuating and stopping a rotating element for example, an actuating shaft of the needle of a sewing machine. The clutch and brake unit has inside it a plurality of friction elements which are mutually engageable in substantial contact, with the interposition of oil of suitable viscosity, and the friction elements are made at least partly of on oil-impregnated, sintered, metallic material, so as to form reservoirs capable of supplying the oil by means of capillarity.
