Hair winder for permanent waves

A hair winder having a winding member on which the hair can be wound, a strip of foil being so attached to the winding member that the strip can be wound onto the winding member together with the hair.

FIELD OF THE INVENTION 
The present invention relates to a hair winder for permanent waving and, 
more particularly, to a hair winder including a spooling device and a foil 
strip attached thereto. 
BACKGROUND OF THE INVENTION 
Permanent waving is intended to set curls in the hair, making use of 
chemical agents which produce a softening of the cellular structure of the 
hair and thereafter fix the hair in an altered shape. Prior to the 
chemical treatment, the hair is usually wound onto very thin (5-16 mm) 
hair winders. The coiled hair is chemically fixed, so that on completion 
of the treatment the hair remains deformed in close curls, substantially 
corresponding to the close windings of the winder. 
Such chemical treatment basically represents a heavy stressing of the 
keratinous cellular structure of the hair and may cause considerable 
damage to the hair if inexpertly performed. As the name indicates, 
permanently waved hair permanently maintains its deformation. It is 
possible to form tight curls (Negroid curls) or gentle soft curls. The 
decisive factor for the tightness of the curls is the diameter of the 
winders. 
There is also the problem of the aftergrowth of hair which is of course 
untreated and of a varying degree of straightness. At the latest after 
approximately six months the difference between the permanently waved and 
untreated hair is visible and the aftergrowth of hair requires renewed 
treatment. 
As already mentioned, every permanent wave treatment stresses the hair 
heavily. As far as possible, therefore, the pretreated hair must be 
protected against being subjected again to chemical stressing which may 
result in considerable permanent damage, such as splitting, brittleness, 
dry dullness--in brief, the impression of dead hair. The industry attempts 
to counteract such damage by the addition of protective substances to the 
permanent waving agents, since it has hitherto been virtually impossible 
to effectively separate prewaved and aftergrowth hair, which are of course 
wound together on a winder, in order to achieve treatment only of the 
aftergrowth with the chemical agents. 
OBJECTS OF THE INVENTION 
It is an object of the invention to improve a simple hair winder of the 
kind specified, which can readily be handled in the home, that only the 
area of hair aftergrowth is treated, the already pretreated zone of the 
hair being left alone. 
Another object is to provide an improved hair winder which can be readily 
used even by unskilled individuals but which will be free from drawbacks 
of earlier devices. 
SUMMARY OF THE INVENTION 
These objects are attained according to the invention by providing the hair 
winder with a strip or foil so attached to the winding member or spooler 
that the strip can be wound onto the winding member together with the 
hair, something which greatly facilitates the winding-on of the hair tips. 
As winding continues, from free ends inside to the roots outside on the 
spooler, the hair automatically covered by the foil is protected, only the 
aftergrowth being accessible for treatment. 
The permanent wave winder according to the invention represents a device 
which is simple and uncomplicated and which can be mastered not only by 
specialist hairdressers, but also by domestic users. The winder calls for 
no new technology and is used in precisely the same way as the prior art 
permanent wave winders. The diameters for obtaining tight or soft curls 
can also remain unchanged. 
According to the invention, therefore, a strip of foil is attached to the 
prior art plastic winder which is preferably of the same width as the 
latter and whose length corresponds to the length of the pretreated hair 
which is to be protected against a repeated treatment. 
The hair to be treated is wound on in the usual manner, the strip of 
preferably thin, liquid-impermeable thermoplastic foil being wound on 
together therewith and the hair not to be treated being reliably protected 
beneath the foil. When the aftergrowth of hair is reached, the excess 
length of the strip can simply be cut off, so that in the continuation of 
the winding process the hair can no longer move under the foil and is 
therefore completely accessible for treatment. This is a simple way of 
preventing pretreated permanently waved hair from being given two 
aftertreatments or more. 
The foil can be attached to a preferably polypropylene or polystyrene 
winder in the simplest manner by sealing, gluing, stapling or spiking on 
short pins. A special construction of such winders comprises a combined 
jacketing with adhesive ribbon and a strip of foil attached thereto. 
According to a feature of the invention, the strip of foil is attached by 
one of its narrow edges to the winding member or spool and is disposed 
between heads of larger diameter at the two ends of the spool. The strip 
is preferably rectangular with its length extending from the shank of the 
spool between the two heads and the foil can be attached to the spool by 
heat sealing, gluing or adhesive application, stapling, hooking or even by 
a Velcro (hook and loop) fastener. 
According to this invention, moreover, an adhesive strip is disposed on the 
spool for the attachment of the strip of foil which preferably is a thin 
thermoplastic member, e.g. of polyethylene, polypropylene or 
polyvinylchloride. The winding member or spool can be enclosed by an 
adhesive ribbon having projecting hooks, pins or bristles. 
The adhesive ribbon can project laterally in the form of a strip beyond the 
spool and can extend substantially parallel to the strip of foil. 
In a preferred embodiment of the invention the adhesive ribbon can have a 
length similar to the strip of foil. The outside of foil strip can have an 
adhesive zone, more particularly, a region provided with projecting hooks, 
pins and/or bristles. The strip of foil can be composed of relatively 
stiff adhesive ribbon having at least one turn forming the spool. A rear 
side of the adhesive ribbon can be rendered impermeable to liquid by 
coating or lamination with thermoplastic foil where a nylon ribbon forms 
the strip and is permeable to air and liquids. The ribbon can have a 
surface formed with nylon adhesive hooks or mushroom strapped adhesive 
bristles.

SPECIFIC DESCRIPTION 
A hair winder has a winding member or spool 1 with each of whose ends an 
enlarged head 3 is integral, one head having a coaxially projecting knob 2 
onto which a rubber band is looped which can be releasably attached by its 
other end in notches in the opposite head to retain the winder after a 
lock of hair has been wound thereon. 
A rectangular strip of foil 5, e.g. a polyethylene foil, is attached by its 
shorter traverse side 5a to the winding member 1 axis parallel between the 
two heads 3 on the jacket-shaped outside (FIG. 1). 
The flag-shaped strip of foil 5 has, as a rule, a greater length L than 
width B, to enable a sufficiently long zone of hair to be enveloped and 
thereby covered by the strip of foil 5. The length L of the strip of foil 
5 can be shortened as required. The strip of foil preferably consists of a 
thin, thermoplastic foil. 
As shown in FIG. 2, the winding member 1 is enclosed by an adhesive ribbon 
6 from whose outside hooks, pins and/or bristles 6a project. In the 
embodiment shown in FIG. 2 the adhesive ribbon 6 encloses only the outside 
of the winding member 1 and does not project. In contrast, in the 
embodiment illustrated in FIG. 4 the adhesive ribbon forms a second strip 
8 which projects laterally beyond the winding member and which can 
preferably lie parallel with the strip of foil 5 and therefore be wound on 
with said strip. The adhesive ribbon 8 has a shorter length than the strip 
of foil 5. 
In another, alternative embodiment the outside of the strip of foil 5 has 
an adhesive zone, more particularly with projecting hooks, pins and/or 
bristles. The strip of foil can also consist of a relatively stiff 
material, so that it forms the winding member at the same side. As a 
result of coating or by lamination with thermoplastic foil, the rear side 
of the adhesive ribbon is also liquid-impermeable. 
In the embodiment shown in FIG. 5 there is no actual separate spool, but a 
winding member is formed by an initial turn or turns of a winding of the 
strip of foil and/or the adhesive ribbon; here again the outside is 
provided with an adhesive zone with hooks, pins and/or bristles. The strip 
of foil and/or the adhesive ribbon can be a foil laminate. 
In the embodiment illustrated in FIG. 5, therefore, more particularly in 
combination with a coating or a foil laminate, the adhesive ribbon forms a 
roll of foil or ribbon which takes over the complete function of the hair 
winder. 
In the case of the hair winders of FIGS. 1 and 2, a lock of hair to be 
treated with the solution or gel utilized for permanent waving, is placed 
on the roller 1 which is coiled to wind the free end of the lock of hair 
inwardly of the foil strip 5 until the only part remaining is the section 
of hair adjoining the roots which has not been treated previously with the 
permanent waving solution. At that point, the balance of the strip 5 is 
cut off and winding continued for a loose or tight curl as the user 
desires and the curler is held in place by looping a rubber band around 
the knob 2 and into the notches of the crenolated head 3 at the opposite 
end of the curler from the knob 2. After the hair curlers are placed over 
the entire head as may be desired, the hair that is exposed at each hair 
curler is only the length which has grown in since a prior waving and the 
hair can be treated with the permanent waving solution. Since the inner 
turns on each curler are protected by the liquid impermeable strip 5, 
previously treated hair is not subjected to a detrimental subsequent 
treatment. However, untreated hair is permanently waved with the applied 
perm solution and fixation. The hair can then be rinsed in the usual 
manner after the curlers have been removed. 
The embodiment of FIGS. 4 and 5 are used similarly except that retention 
may be effected by the hook and loop fasteners and rubber bands may not be 
necessary to retain the curlers in place. Key to the invention, of course, 
is that it interposes a liquid impermeable strip between previously 
treated hair and hair to be treated in a subsequent application.
