Abstract
A convertible hair roller includes first and second flexible outer sheets connected together in parallel spaced relation, two parallel memory wires positioned between the sheets and capable of repeated deformation between a straight configuration and a circular configuration, with each memory wire automatically deforming from the straight configuration to the circular configuration upon application of heat of a predetermined temperature thereto so that the first and second sheets also automatically deform into a cylindrical configuration; and heat sink wires positioned transversely with respect to the memory wires between the first and second sheets for retaining heat applied to the hair roller. When heat is removed from the formed memory wires, they retain their circular configuration, but can be manually biased back to their flat configurations. In addition, apparatus for heating the hair rollers includes a positioning device which positions a cylindrically formed hair roller thereabout and a heater associated with the positioning device for heating a hair roller to cause the hair roller to automatically wrap about the positioning device into the cylindrical configuration.
