ABSTRACT:
A hairsetter for electrically heating a plurality of flexible hair curlers includes a thermally insulated hollow container receiving therein a plurality of vertically disposed elongated flexible hair curlers arranged in a pair of rows. The curlers are heated by a heat sink core portion disposed between the curler rows and in heat conductive contact with the curlers. The heat sink core portion includes a flat electrical resistance heater plate sandwiched between two electrically insulating boards covered by two oppositely facing metallic heat sink members. The heat sink members each have a plurality of vertical channels receiving and contacting a respective one of curlers of a curler row for conducting heat to the curler from the heater plate. The rows of curlers are disposed in a tiered arrangement to facilitate removal of the heated curlers from the container through a top opening on the container closed by a hinged cover.
