Abstract
A hair roller which is comprised of three concentric sleeves. An outer sleeve is of a plastic, woven-type material that has a plurality of projections with hooked shaped ends capable of gripping hair. A central sleeve is comprised of a metallic material having good heat transfer characteristics. An inner sleeve is comprised of a flexible, resilient plastic material which provides the hair roller with more rigidity and acts as an insulator.

A hair roller assembly comprising
- concentrically arranged surface to surface engaged an outer tubular sleeve, an inner plastic perforate support sleeve and an intermediate perforate sleeve therebetween;
- said outer tubular sleeve comprised of a porous woven plastic material having plural spaced circumferential rows each including a plurality of radial outwardly extending flexible projections having hair-grasping hook shaped ends;
- and
- said tubular intermediate sleeve being formed of a highly heat conductive material and having plural rows of spaced oblong openings formed along the length thereof and said inner plastic perforate support sleeve being formed of plural spaced longitudinal parallel strips extending along the length thereof and spaced coaxial ridges unitary with said spaced longitudinal parallel strips thereby to define a plurality of openings along the length of said roller, said inner plastic perforate support sleeve being resilient and flexible.

A hair roller assembly comprising:
- concentrically arranged surface to surface engaged an outer tubular sleeve, an inner plastic resilient semi-flexible perforate tubular supporting sleeve within said outer tubular sleeve and a perforate intermediate tubular sleeve between said outer and inner sleeves, each of said sleeves having opposite ends;
- said outer tubular sleeve is formed of a porous woven plastic material having plural circumferentially spaced relatively narrow rows formed of a plurality of radially outwardly extending flexible hair-grasping projections along the width thereof,
- said intermediate tubular sleeve being formed of thin aluminum, said intermediate tubular sleeve having plural spaced openings formed in rows along the circumferential surface thereof;
- and
- said inner plastic resilient semi-flexible perforate tubular plastic support sleeve having plural spaced strips extending longitudinally along the length thereof and plural coaxial spaced circular ridges extending along the length of said support sleeve and unitary with said spaced strips thereby to define plural openings between the opposite ends of said support sleeve.
