Abstract
A rotary hair brushing and curling appliance includes a hollow rotary barrel of a thermally conductive material mounted to rotate on a handle, and having an external hair-engaging surface. Silicone rubber bristles are mounted on the barrel, and arranged in first and second sets projecting from first and second arcuate surfaces which are axially elongated and circumferentially spaced apart. Heating elements abut respective abutment surfaces inside the barrel. A reversible motor rotates the barrel. The first and second arcuate surfaces each occupy 10% to 40% of the external surface and are subtended at the axis by respective first and second central angles. The heating elements are positioned outside first and second sectors defined by the first and second central angles, focusing the conductive heat transfer to the adjacent relatively large unobstructed external areas of the barrel.
