ABSTRACT:
An electric hair curling apparatus includes an elongated electrically heated barrel extending from a handle and forming a mandrel about which hair may be wrapped to form a curl. The barrel is mounted for rotation about its longitudinal axis relative to the handle and a selectively energized electric motor is provided in the handle for unidirectionally rotating the barrel. An elongated spring-biased wrapping member conforming in shape to the barrel is mounted on the barrel for rotation therewith and is arranged for movement toward the barrel to urge the hair against the barrel and away from the barrel to relax its engagement with the hair. Cooperating camming means on the handle and wrapping member automatically and periodically move the wrapping member toward and away from the barrel, during each revolution of the barrel, in response to the unidirectional rotation of the barrel by the motor.
