Abstract

Abstract A hair roller with which the user''s hair can be wound in a bundle having the strands therein held in windings of varying pitch to give a corresponding varying degree of tension to the hair. Thus the bundle of hair is so controlled that when it is set it possesses a larger curl near the root end and a smaller tighter curl near the tip end giving better overall body to the hair and optimum control over the shaping of the critical tip end. The hair roller comprising a wrapping strip susceptible of being wound upon itself so as to facilitate the winding of the hair therewith into a bundle of hair for setting purposes. The wrapping strip is used in conjunction with a core member of generally cylindrical shape and provided for starting the first winding of the hair at a predetermined diameter. Projections are included on the wrapping strip to space each convolution into which the hair is wound from the others at windings of increasing pitch to impart varying tension to the hair and also allow axial entry of air to the rolled bundle for rapid and more complete drying of the hair. Also, access for radial entry of air to the bundle is provided for by means of suitable openings formed in both the core and wrapping strip.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 156 words
In a hair roller, a core segment adaptable for providing a substantially cylindrical winding surface of predetermined diameter for receiving the tip ends of strands of hair in a first convolute winding of said strands at a predetermined diameter, and an elongated strip having a relatively expansive surFace against which the remaining lengths of said hair strands may be received, said strip being susceptible of being wound in a succession of convolutions and being connected with said core for winding therewith to roll the remaining lengths of said hair strands in corresponding and successive convolutions toward the root ends thereof, said elongated strip further having projections outstanding from the surface thereof for spacing each convolution into which it is wound from the others and therewith providing that the diameter of the hair convolution nearest the root ends is much larger comparatively than the diameter of the first convolute winding of hair received on said core segment.
Claim 2
Dependent Claim 156 words
In a hair roller, a core segment adaptable for providing a substantially cylindrical winding surface of predetermined diameter for receiving the tip ends of strands of hair in a first convolute winding of said strands at a predetermined diameter, and an elongated strip having a relatively expansive surFace against which the remaining lengths of said hair strands may be received, said strip being susceptible of being wound in a succession of convolutions and being connected with said core for winding therewith to roll the remaining lengths of said hair strands in corresponding and successive convolutions toward the root ends thereof, said elongated strip further having projections outstanding from the surface thereof for spacing each convolution into which it is wound from the others and therewith providing that the diameter of the hair convolution nearest the root ends is much larger comparatively than the diameter of the first convolute winding of hair received on said core segment.
Claim 3
Dependent Claim 29 words
The hair roller of claim 1, wherein said core segment is an essentially flat strip connected with said elongated strip but capable of being wound into a cylindrical shape.
Claim 4
Dependent Claim 24 words
The hair roller of claim 2, wherein said flat strip further includes securing means with which it can be secured in said cylindrical shape.
Claim 5
Dependent Claim 59 words
The hair roller of claim 3, wherein said securing means includes interengaging bosses carried on said flat strip and a plurality of apertures formed in said flat strip, said apertures being arranged such that said core segment can be secured in one of a number of different diameters by receiving said bosses in correspondingly different ones of said apertures.
Claim 6
Dependent Claim 17 words
The hair roller of claim 4, wherein said elongated strip and said flat strip are made integral.
Claim 7
Dependent Claim 28 words
The hair roller of claim 5, wherein said elongated strip and said flat strip are each provided with a plurality of apertures constituting ventilation openings for said device.
Claim 8
Dependent Claim 67 words
The hair roller of claim 5 further comprising an elastic cord connected to said flat strip adjacent its juncture with said elongated strip and having sufficient length to be passed through said core and back across said elongated strip to hold the latter against said core when wound in convolutions, said flat strip having slits in the margins thereof for receiving an enlarged end of said cord.
Claim 9
Dependent Claim 36 words
The hair roller of claim 1, wherein said core segment is a shaped cylinder of predetermined diameter, said cylinder having a longitudinal slot therein, an end portion of said elongated strip being receivable in said slot.
Claim 10
Dependent Claim 27 words
The hair roller of claim 8, wherein both said elongated strip and said cylinder are provided with a plurality of apertures constituting ventilation openings for said device.
