Abstract
Method and apparatus for setting hair by successively passing steam and cooling air through said hair while wound on rollers.
Claims11
Process for setting hair which comprises the steps of subjecting at least partially dry hair wound on a tubular member to the action of dry steam at a temperature between 100.degree. and 150.degree. C. for a period of 1 to 60 seconds and then cooling said hair to the ambient temperature by directing a current of cooling gas thereagainst while still on said member, after which the hair is unwound from said member.
Apparatus for treating coiled hair comprising a body provided with:
- handle means,
- a reservoir for liquid,
- means for withdrawing from the reservoir a predetermined quantity of liquid,
- a vaporizing member comprising a resistance heater and into which the liquid withdrawn from the reservoir passes and in which steam is generated from the liquid,
- an injector supplied by the vaporizing member, said injector being adapted to bring into contact with the hair to be treated said steam at a temperature of 110.degree. to about 150.degree. C., said injector comprising a hollow needle having a rounded end and having orifices near the rounded end adapted to permit the passage of steam, these orifices being inclined with respect to the axis of the needle and rearwardly directed.
Apparatus for treating coiled hair comprising a body provided with:
- handle means,
- a reservoir for liquid,
- means for withdrawing from the reservoir a predetermined quantity of liquid,
- a vaporizing member comprising a resistance heater and into which the liquid withdrawn from the reservoir passes and in which steam is generated from the liquid,
- an injector supplied by the vaporizing member, said injector being adapted to bring into contact with the hair to be treated said steam at a temperature of 110.degree. to about 150.degree. C.,
- said injector having lateral outlet orifices and being encircled by a telescopic protective sleeve which, when at rest, is biased toward a position in which it blocks said outlet orifices, said vaporizing member being then placed in communication with orifices positioned laterally on the body of the apparatus, while in the operating position the sleeve is biased toward a position clear of the orifices in the injector and blocks the orifices positioned laterally on the body of the apparatus.
Apparatus for treating coiled hair comprising a body provided with:
- handle means,
- a reservoir for liquid,
- means for withdrawing from the reservoir a predetermined quantity of liquid,
- a vaporizing member comprising a resistance heater and into which the liquid withdrawn from the reservoir passes and in which steam is generated from the liquid,
- an injector supplied by the vaporizing member, said injector being adapted to bring into contact with the hair to be treated said steam at a temperature of 110.degree. to about 150.degree. C.,
- said injector consisting of a hollow needle surrounded by a protective member consisting of a rubber blower and a conical spout.
Apparatus for treating coiled hair comprising:
- a body equipped with handle means,
- a reservoir for liquid in said body,
- means for withdrawing a predetermined quantity of liquid from said reservoir,
- a vaporization chamber comprising a heating resistance and into which the liquid from this reservoir passes and in which steam is generated,
- a tubular member having a low thermal inertia on which the hair to be treated is coiled, said tubular member having perforations through which the steam produced by the vaporizer is applied to said hair at a temperature between 110.degree. and 150.degree. C.,
- blowing and sucking means adapted to drive through the coiled hair a current of ambient air which does not pass through the vaporizer.
