ABSTRACT:
A hair roller adapted to be heated by being positioned on a hot post of a hair setting unit, consists of a plastic, cylindrical and hollow outer body, provided with outstanding teeth on its outside surface. It is closed at its upper end and open at its lower end, its hollow portion being cylindrical in its upper part, extending to about two thirds of its length, and the remaining lower third is tapered towards the lower opening. A tubular insert, made of a resilient aluminum alloy, extends the length of the hollow portion. It is longitudinally slit over its entire length, and the two edges of the slit extend to both sides of an inwardly projecting longitudinal ridge provided in the cylindrical part of the hollow portion. The insert is provided with an outwardly projecting lug on one edge of the slit, which engages with a perforation or a recess in the outer body. The insert is slotted by parallel slots extending from its lower end as far as the tapered hollow portion, a feature permitting positioning of the roller on a frusto-conical, heated post of a hair setter unit in metal-to-metal contact over the entire slotted portion.
