The strip is bonded by a rubber type polymer neoprene (pref. contact adhesive to a blade (13) formed from a corrosion resistant clock spring steel. Two other similar blades of steel (15) may be added or dispensed with according to the case. All blades pref. have a hole (17) for a screw by which they are fixed to the rotary plate.
