set. With permanent waving, the hair is subjected to the action of chemicals while it is wrapped in this way, which are required for the effective effect "that the hair is under considerable stress caused by a sharp draft of air and by cellaring the strand of hair · For water waves or hairstyling, the winding can be looser, but the strand of hair must be wound Hold shape until the hair has taken on the water wave.

With both permanent waving and water waving, the strand of hair, when it is wound, can be removed from the core or can be removed from the bar with the proviso, that it is securely protected against being wound up, as is the case with the usual "finger-winding" method, in which the strand of hair is wrapped around a finger and this wound strand is stripped from the finger and is set in coiled form with the help of a bobby pin.

Next few women find it easy and "comfortable", theirs Wind your hair on the bars yourself. Second, you usually need end papers at the tips of the hair strands can be used to facilitate the beginning of wrapping around the bar. Bundling the hair around the bar also makes it difficult to use corrugating liquids "up to the syringes of the first wrapped around the rod To let Haaues penetrate

Looser windings are desirable for water waves or hairdressing purposes. The more well-known method is that the women of this Z _we ck "use their fingers. But due to lack of skill many women are not able to produce uniform winding you are not in a position, the tips of the hair in the. At present, large diameter curlers are used for hairdressing, but they also suffer from the above-mentioned problem that women have difficulty in winding the hair onto the curlers, particularly at the back of the head.

It has already been proposed to suck the strand of hair into a hair curler, which has the shape of a suitable air-permeable container has through a stream of air which is guided so that it is in a general axial path through the container, while the lock of hair is pressed into the curler by the air pressure will. This method has great advantages over hand winding, not only because it is a difficult task to wind up the strands of hair on the clasp, but also because it eliminates the need to separate the " Enables streaking or "splitting" that usually precedes treading, or in some "cases" the water waves. Further advantages are a greatly increased speed, the elimination of end papers, to leave the wound strand of hair much better free and to remove part of the moisture., from a wet strand of hair through the air stream, in order to achieve an even penetration of the strand of hair through subsequently To facilitate applied solutions, such as permanent waving.

However, the procedure has several disadvantages · The hair *

Strand has a tendency to deposit itself in random coils that are not concentric about any single axis and are not of regular or controlled size and shape, and while such coiling, which is left to chance, can be conducive to permanent waving Generally undesirable for hairdressing · By skillful manipulation during the treatment of the hair, it is possible to deform the strand of hair into a series of spiral windings which are concentric to the winder axis and continue in the longitudinal direction, as in the case of spiral winding on a rod. Arrangement is more desirable because it creates symmetrical curls of a size and shape affected by the shape and dimensions of the curler, but the necessary handling requires skill, is tedious, and even if done skillfully, no where under certain circumstances not for winding of the desired uniformity, in particular b Regarding the direction, lead · In addition, with this treatment it is not feasible to wind the strand of hair radially to the winder axis on itself, as is the case with croquinole-

be changed to reverse the sighting by the Presence of the central shaft · This process invariably produces uniform coils of the desired Direction achieved, so that "especially when Wassexwellen the direction of the curls of a number of strands of hair over the whole head can be precisely controlled. Accordingly, if the hair is combed and styled, they will fit Curls or the curl pattern of each strand of hair to that of other strands of hair, so as to give a smooth finished hairstyle · This way get great Ropes a woman's hair to look as if washed they would be lured as single large masses.

In the case of water waves, it is also particularly important that the laps produced are of the same size, ie the same diameter. It has been shown that this is mainly influenced by the diameter of the curler used, which can have a diameter of 25 to 50 mm for water waves, in order to create curls of the same diameter, namely a diameter that is slightly smaller than that of the curler “Iet as fully assured below.

Perms as well as, for water-waving and "alleviate certain difficulties" in perming with the help of curlers in their previous lOrms. This is because of the uniform nature of the curls that are created and which are automatically and evenly sighted and of uniform diameter with a single curler and they can be quickly and conveniently placed in every winder in there? desired winding direction can be introduced by the simple handles described above · Furthermore, the hair curlers according to the invention can create curls of uniform diameter. the entire strands of hair of literally any length produce under the gate exposure that the length of the curler is sufficient.By changing the transverse dimensions of the curlers, curls of almost any diameter can be created and if desired, the curl diameter can be changed over the length of the hair strand by Changing the cross section of the curler along its length. Numerous shapes of curlers can be used, such as a frustoconical curler whose mouth at the wider diameter end creates curls that are smaller in diameter near the ends of the strand of hair, while a

-45- 809813/0546

larger or onion-shaped or spherical cross-section between creates a strand of hair at the ends of the curler that has larger curls between its ends.

As is clear, the Eockenwickler according to the present invention are e _r not only useful when placing the hair into the desired final shape, but also in the permanent waving. In such a case, the strand of hair, which is usually treated with water, can be treated with a permanent wave solution in the usual manner. The application of a permanent wave solution can be carried out before or after the winding of the strand of hair, or the permanent wave solution can be carried out both before and after winding the strand of hair »the porosity of the curler allowing free penetration of the permanent wave solution to the strand of hair if it is brought into action after the strands of hair wound in the curlers have been removed from the suction device.

Desirable enough, the hair curler according to the present invention E _r to the higher comfort of the wearer "are flexible, in particular for perms or water waves over night. However, the curler can also rigid and substantially non-deformable sine, if desired.

The dimensions of the curlers are variable over a considerable range, depending on a number of factors. The diameter of the curler mouth is related to the width or diameter of the strand of hair to be treated in the curler. For a strand of hair of a given size, there is a corresponding minimum diameter that the curler mouth should have in order to allow the strand of hair to pass straight through.Where the airflow device is used to form or select the hair strand, the diameter of the curler mouth should be well above the Minimum go beyond the size of the strand of hair that is to be formed. The ^{diameter of the} curler body and its length depend on each other, as well as on the lOrm of the curler and the length and size of the strand of hair that the curler

-47-809813 / 0546

U5740S

winder should take up. They should have such a volume that the desired length of hair strand is tightly wound and can be packed into it by the air flow. If ' the curler is too short or too small to take up the entire length of the strand, it will still work normally as to the length that can be wrapped in it. On the other hand, if the curler were too long, the consequence would be that the density of the strand of hair wound in it would be reduced would decrease. Still, a single size curler can cover a considerable range of hair strand lengths and sizes are used. Preferably, a set of curlers of different sizes is included Applied to a specific head hair to accommodate the different lengths of hair on different parts of the head it is.

The diameter of the curler body is important as it determines the density of the curler and the extent of permanent or temporary curling. Again, there is a relationship to the size of the hair strand to be treated. I ¹ ur a strand of hair 75 to 150 mm in length and a weight of about 3 grams, which is assumed to be the usual hair, strand size for most of the hair

can be, it has been shown that the transverse dimensions of the curler can be about 25 or 50 mm for water waves, so that curls of a slightly smaller diameter than that of the curler body can be made ·; Smaller diameter hair curlers can be used to create a permanent wave that can be compared to ^{x being} a medium to sharp wave at ^x which is considered to be rod waves and is essentially uniform along the entire length of the strand, with the ioptimal hair curler diameters in the G. - of the order of 15 mm in diameter for the mouth and body of the curler are approximately 25 mm in length. By using an end cap of decreasing diameter, sharp development can be achieved.By changing the curler diameter, curls can be created by changing tightness along the length of the strand.

Ba general, to achieve the full range of locks diameters in such hair strands that are today uerwellen the D _a desirable mm go the diameter of the curler up to 38, but should not significantly exceed this and the diameter should not be "less than 6 mm. diameter of curls used for water waves

are desired, can be slightly larger and for this Purpose can be the diameter of the curler area for acceptable results for most! rough between be about 18 mm up to 62 mm

For shorter hair lengths and for end curling, shorter curler lengths are desirable with a minimum of about 6 mm Diameter than that of the curler body in order to limit the size of the selected hair strands · In the case of curlers with a small diameter it may be desirable to widen the mouth to allow the strand of hair to enter between the curler walls and äeaa. To facilitate middle shaft.

In general, the curler mouth diameter will be equal to or less than the curler length Usually, the length of the curlers does not exceed about 65 Baa, but much longer curls

Device used to select the strands should be the the opening receiving the strand does not exceed in size substantially the minimum required for the size of the strand is necessary to be selected.

The diameter of the rotating shaft portion within the curl should usually in ratio to that of the hair curler to be small and in general of the same order of magnitude as the waste from the usual today rods to produce the desired W _e or shape, at least doet where the strand of hair directly on them is curled, usually on the order of 3 mm or less. Desirably the diameter should not be so large as to unduly narrow the space between the shaft and the surrounding curler wall so that the lock of hair must be pressed tightly therebetween. The shaft should be smooth lengthways so that hair does not get caught on it, but it could be hollow with an open inner base end and could have holes so that air can be passed through to hold a lock of hair against suction. The shaft of round

For a while this can go from 5mm to 10mm while slightly larger diameters can be used for water waves. Where an outside surrounding container for the curl is used, as with most of the embodiments, the inside diameter of the container should be quite large adjust close to that of the desired hair strand coils. For permanent waving this can desirably be in the range of 13 to 19 mm, while for water waving it can be slightly larger Diameter s he can be used · IHir 0 ro quinol e winding the length of the container is such that one receives the strand of hair Slit is created that is long enough to accommodate the width of the strand of hair when used as a flat, thin layer is spread out, which is one thing that is desirable with this type of wick
