Abstract: A curly hair curing iron having a jerking portion which does not exert a severing action on the hair and a stretching portion for making the hair straight. The iron is a scissors type iron having a rod housing with heaters therein. The inlet side constitutes the jerking portion having a strong gripping force. The outlet side constitutes the stretching portion having a weaker gripping force than the jerking portion. The jerking portion includes convex portions 8, 9 and 10 on one rod, and plane portions in engagement with the convex portions on the opposite rod. The stretching portion has a plurality of convex portions 11 on one rod which are square or trapezoidal in section and a plane on the other rod. Both the convex portions and the plane portions on both the jerking portion and the stretching portion are formed of an elastic material.

Abstract: This invention relates to a curly hair correcting iron for correcting natural curly hair into straight hair. The iron comprises two rods containing therein heaters, respectively, one rod having its surface provided with two spaced rows of projections which are triangular or semicircular in section, the other rod having its surface likewise provided with a row of projections which also are triangular or semicircular in section so as to be positioned between the two rows of projections on the first rod, whereby when hair is sandwiched therebetween it is curved into a U-shape or a V-shape. The hair is held and pulled in the direction of the hair end thereby exerting strong drawing, heat and tension on the hair to extend it. To dampen pressure, it is preferable that a resilient layer be pasted onto the rod surface, and to dampen the action of heat to enhance the efficiency, it is desirable that the resilient layer be formed of a material having a far infrared radiation.

Abstract: Since the hair well absorbs far infrared radiation in the range of 5 to 10 .mu.m, a material for radiating the far infrared rays having such a wavelength band, more specifically, ceramics, such as zirconia magnetite or alumina, is used on the outer surface of a rod of a curling iron. By applying a ceramic which can radiate far infrared rays to a rod of a curling iron, the temperature of the rod may be decreased to a level from 100.degree. C. to 150.degree. C. The ceramic layer is further coated on its outer surface with a metallic anti-corrosion layer of nickel-chrome or nickel-aluminum to withstand chemicals.

Abstract: An electric curling iron for producing a spiral curl giving the impression of a stream-like natural and soft wave is constructed in the form of a scissors having one blade comprising an electrically heated rod and the other blade comprising a clamp cooperating with the rod to press hair to be curled therebetween. The surface of the rod has a plurality of side by side spiral polygonal edges. The clamp is an arcuately shaped cover longitudinally coextensive with the rod and in contact with the polygonal edges thereby, leaving a free space between the clamp and heater rod for the escape of vapor. The arcuately shaped clamp may have a radius smaller than that of the rod and may be provided with a rubber cover. Since the edges are obliquely pressed against the hair during use possible hair damage by heat and pressure is reduced.
