Abstract
Abstract An improved hair roller or permanent wave rod comprising a cylindrical member on which the hair is wound, and a flexible strap or band, the cylindrical member and the ends of the strap having self-adhering material which has a high resistance to shear forces in the plane of contact of the material but can be readily separated by force perpendicular to the plane of contact of the material. The rod may have flanged ends to provide an increased area of contact of the material. One type of material suitable for use in the invention is a hook and loop fastening material known as "VELCRO", a registered trademark of Velcro America.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
A hair roller comprising a cylindrical member having a cylindrical body upon which the hair is wound and end surfaces at the ends thereof; and an elongated strap member, having a center portion substantially the same length as the longitudinal axis of the cylindrical member with a width substantially equal to the diameter of the cylindrical member and end portions at each end of the strap member, which end portions may be folded at substantially right angles to the center portion; the end surfaces of said cylindrical member and the end portions of said strap member each being provided with mating surfaces of self-adhering material, whereby the strap member may be affixed to the cylindrical member at each end.
Claim 2
Dependent Claim
119 words
A hair roller comprising a cylindrical member having a cylindrical body upon which the hair is wound and end surfaces at the ends thereof; and an elongated strap member, having a center portion substantially the same length as the longitudinal axis of the cylindrical member with a width substantially equal to the diameter of the cylindrical member and end portions at each end of the strap member, which end portions may be folded at substantially right angles to the center portion; the end surfaces of said cylindrical member and the end portions of said strap member each being provided with mating surfaces of self-adhering material, whereby the strap member may be affixed to the cylindrical member at each end.
Claim 3
Dependent Claim
39 words
A hair roller as claimed in claim 1, in which said self-adhering material is of the type having high resistance to shear forces in the place of contact between the ends of the cylindrical member and the strap member.
Claim 4
Dependent Claim
22 words
A hair roller as claimed in claim 2, characterized by the self-adhering material being a hook and loop material such as VELCRO.
Claim 5
Dependent Claim
18 words
A hair roller as claimed in claim 1, characterized by said strap member being formed of flexible material.
Claim 6
Dependent Claim
27 words
A hair roller as claimed in claim 4, further characterized by a longitudinal slit extending for substantially the length of the center portion of said strap member.
Claim 7
Dependent Claim
24 words
A hair roller as claimed in claim 1 in which the strap member has self-adhering material on both surfaces of the end portions thereof.
Claim 8
Dependent Claim
55 words
A hair roller as claimed in claim 1 in which the cylindrical body of the cylindrical member is formed with a slot passing through the body along a substantial portion of its length, such that the hair may be passed through the slot and wound upon the body by rotation thereof along its longitudinal axis.
Claim 9
Dependent Claim
49 words
A hair roller as claimed in claim 1 in which the cylindrical body of the cylindrical member is provided with mating strips of hook and loop self-adhering material around its circumference at the ends thereof, having mating hook material and loop material at opposite ends of the cylindrical body.
