Beschreibung
Zusammenfassung:	A ripple-shaped tightening strip disposed in radical slots of the core of an electric machine stator between the slot wedge and winding bar and comprising a rippled insulating member and an elastomeric resilient member fixed in the troughs of the rippled member. Such a strip has an increased strength, provides for a considerable total radial force and sufficient taking-up of the clearance between the slot wedge and the winding bar to compensate for its variations in a radial direction, caused by heat and electromagnetic forces when the electric machine is in operation.
