Description

Glätteinrichtung  smoothing
Die vorliegende Erfindung betrifft eine Glätteinrichtung mit zwei schwenkbar aneinander gelagerten Armen zum Glätten von Fasern bzw. Haaren. The present invention relates to a smoothing device with two arms pivotally mounted on each other for smoothing fibers or hair.
Heutige Glätteinrichtungen zur Erzeugung von Glätte und Glanz in Haaren bzw. Fasern sind in der Regel derart konstruiert, dass die Haare/Fasern durch manuelle Bewegung oder Rotation überstrichen werden. Im Falle einer als Haarglätter ausgebildeten Glätteinrichtung führt das jedoch dazu, dass die Haare mehrmals mit heißen Glättelementen, bspw. heißen Glättplatten, gegriffen und jeweils ausgestrichen werden. Dem liegt die Tatsache zugrunde, dass sich das Glättergebnis bis zu einem gewissen Punkt mit der Anzahl der Glättoperationen verbessert. Glätten der Oberfläche bedeutet dabei gleichzeitig auch einen optischen Glanzeffekt, der meist aus ästhetischen Gründen zusätzlich erzielt werden soll. Im Fall eines Haarglätters wirkt die Hitze bei dieser Anwendung natürlich häufiger und intensiver auf das zu glättende Haar ein und kann dabei unter Umständen zu Schäden führen. Häufiges und intensives Kämmen erzeugt einen ähnlichen Effekt, allerdings wiederum verbunden mit einer möglichen Schädigung der Haare. Die vorliegende Erfindung beschäftigt sich daher mit dem Problem, für eine Glätteinrichtung der gattungsgemäßen Art eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die eine möglichst schonende, gleichzeitig aber effektive Glättung von zu glättenden Haaren bzw. Fasern ermöglicht. Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche. Today's smoothers to produce smoothness and shine in hair or fibers are typically designed to sweep the hair / fibers by manual movement or rotation. In the case of trained as a hair straightener, however, this means that the hair several times with hot smoothing elements, eg. Hot smoothing plates, gripped and struck each. This is due to the fact that the smoothing result improves to some extent with the number of smoothing operations. Smoothing the surface means at the same time also an optical gloss effect, which is usually also achieved for aesthetic reasons. In the case of a hair straightener, the heat in this application, of course, more frequently and more intensively on the hair to be smoothed and may possibly lead to damage. Frequent and intense combing produces a similar effect, but in turn associated with possible damage to the hair. The present invention therefore deals with the problem of providing a smoothing device of the generic type an improved or at least one alternative embodiment, which allows the gentlest as possible, but effective smoothing of hair or fibers to be smoothed. This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, bei einer an sich bekannten Glätteinrichtung mit zwei schwenkbar aneinander gelagerten Armen, zwischen denen Haare bzw. Fasern beim Glätten hindurch gezogen werden, an zumindest einem der Arme der Glätteinrichtung wenigsten ein schwingendes Glättelement vorzusehen, das derart schwingt, das beim Durchziehen der Haare bzw. Fasern während des Glättens zumindest einzelne Stellen der Haare bzw. Fasern mehrfach überstrichen und dadurch deutlich besser geglättet werden. Hierdurch kann eine besonders intensive, andererseits aber durch eine reduzierte Wärmeeinwirkung auch schonende Glättwirkung erzielt werden, da durch das zumindest eine schwingende Glättelement während einer normalen Anwendung der zurückgelegte Weg in Bezug auf die Oberfläche der Faser bzw. des Haares vervielfacht wird. Im Vergleich zu einer bisherigen Glätteinrichtung, bspw. im Vergleich zu einem bisher bekannten Haarglätter, werden somit bei der erfindungsgemäßen Glätteinrichtung die zu glättenden Fasern bzw. Haare während eines einzigen Durchziehens mehrfach überstrichen und dadurch deutlich stärker geglättet. Insbesondere bei Haaren ist dabei darauf zu achten, dass die Schwingung in einer für das Haar günstigen Richtung, das heißt bspw. in Richtung der Schuppen, erfolgt, wodurch der während des Glättens entstehende Glanzeffekt zusätzlich verstärkt werden kann. Eine der Arbeitsrichtung der Glätteinrichtung angemessene Schwingungsrichtung könnte dabei bspw. durch eine entsprechende Sensorik (Bewegungssensor) sowie eine automatisch umschaltende Schwingungseinrichtung erreicht werden. Denkbar ist selbstverständlich auch, dass die erfindungsgemäße Glätteinrichtung eine Vorzugsrichtung aufweist. Mit der erfindungsgemäßen Glätteinrichtung ist somit ein besonders effektives, gleichzeitig jedoch auch schonendes Glätten von insbesondere Haaren möglich. Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung ist das zumindest eine Glättelement als Heiz-/Kühlplatte ausgebildet oder aber zusätzlich zu einer Heiz- /Kühlplatte an einem Arm der Glätteinrichtung angeordnet. Selbstverständlich kann zumindest eines der Glättelemente an einem Arm auch als Heiz-/Kühlelement und am anderen Arm als Kühlelement ausgebildet sein. Hierdurch eröffnen sich mehrere Möglichkeiten zum Anordnen bzw. Vorsehen des erfindungsgemäßen schwingenden Glättelements, das sowohl zusätzlich zu einer feststehenden Heizplatte/Kühlplatte am Arm der Glätteinrichtung angeordnet werden kann oder aber bspw. selbst die Funktion der Heiz-/Kühlplatte übernehmen kann. Selbstverständlich ist auch eine Anordnung mehrerer schwingender Glättelemente zusätzlich zu einer fixen Heiz-/Kühlplatte oder die Anordnung mehrerer schwingender Glättelemente, wovon eines oder mehrere davon als Heiz-/Kühlplatte ausgebildet sind denkbar. Vorzugsweise kann auch eine mittige, feststehende Heiz-/Kühlplatte vorgesehen werden, an deren Längsränder jeweils ein schwingendes Glättelement angeordnet ist und dadurch die zu glättenden Fasern bzw. Haare gerade im Bereich der Heiz-/Kühlplatte glatt ziehen, wodurch ein besonders effektives Glätten ermöglicht wird. Besonders ein Heizen am einen Arm und ein Kühlen am gegenüberliegenden Arm erzeugt ein besonders effektives Glätten. The present invention is based on the general idea, in a known per se smoothing device with two pivotally mounted arms, between which hair or fibers are pulled when smoothing through to provide at least one of the arms of the smoothing least one oscillating smoothing element, the vibrates in such a way that when pulling through the hair or fibers during smoothing at least individual points of the hair or fibers are repeatedly crossed over and thereby significantly better smoothed. In this way, a particularly intensive, but on the other hand by a reduced heat also gentle smoothing effect can be achieved because is multiplied by the at least one vibrating smoothing element during normal use of the distance covered with respect to the surface of the fiber or hair. Compared to a previous smoothing device, for example. Compared to a previously known hair straightener, the fibers to be smoothed or hair are thus repeatedly painted over during a single pull through and thus significantly smoother in the inventive smoothing device. In the case of hair in particular, care must be taken that the vibration takes place in a direction favorable for the hair, that is to say, for example, in the direction of the scales, as a result of which the gloss effect arising during smoothing can be additionally reinforced. An oscillation direction appropriate to the working direction of the smoothing device could be achieved, for example, by means of a corresponding sensor system (motion sensor) and an automatically switching oscillation device. Of course, it is also conceivable that the smoothing device according to the invention has a preferred direction. With the smoothing device according to the invention thus a particularly effective, but at the same time gentle gentle straightening of particular hair is possible. In an advantageous development of the solution according to the invention, the at least one smoothing element is designed as a heating / cooling plate or arranged in addition to a heating / cooling plate on one arm of the smoothing device. Of course, at least one of the smoothing elements on one arm can also be designed as a heating / cooling element and on the other arm as a cooling element. This opens up several possibilities for arranging or providing the vibrating glazing element according to the invention, which can be arranged in addition to a fixed hot plate / cooling plate on the arm of the smoothing device or, for example, even take over the function of the heating / cooling plate. Of course, an arrangement of several oscillating smoothing elements in addition to a fixed heating / cooling plate or the arrangement of several oscillating smoothing elements, one or more of which are designed as a heating / cooling plate is conceivable. Preferably, a central, fixed heating / cooling plate can be provided, at the longitudinal edges of each a vibrating smoothing element is arranged and thereby the fibers to be smoothed or Smooth hair straight in the area of the heating / cooling plate, which enables particularly effective smoothing. Especially a heating on one arm and a cooling on the opposite arm creates a particularly effective smoothing.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung ist an beiden Armen der Glätteinrichtung jeweils zumindest ein schwingendes Glättelement angeordnet, die sich gegenüberliegen und die symmetrisch bzw. unsymmetrisch zueinander schwingen. Durch die sich gegenüberliegenden, schwingenden Glättelemente, werden das Überstreichen und dadurch auch das Ziehen der Haare während des Glättvorgangs zusätzlich verstärkt, wodurch auch der Glätteffekt zusätzlich verstärkt werden kann. Hier kann auch eine rein lineare Bewegung erfolgen, beispielsweise zuerst eine vertikale Bewegung auf das zu glättende Haar zu, dann eine Bewegung in Richtung des Haares, dann eine Bewegung vom Haar weg und abschließend eine Bewegung zurück zum Ausgangspunkt, wodurch ein Viereckbewegung erreicht wird. Zweckmäßig ist eine Schwingungsrichtung des zumindest einen schwingenden Glättelements einstellbar, wobei zusätzlich oder alternativ eine Sensoreinrichtung vorgesehen sein kann, die die Durchzugsrichtung der zu glättenden Haare/Fasern erkennt und daraufhin die Schwingungsrichtung des zumindest einen Glättelements entsprechend ausrichtet bzw. einstellt. Da insbesondere eine Schwingung entgegen einer Schuppenrichtung der zu glättenden Haare zu einem stumpfen Erscheinungsbild der Haare führen würde, ist es wünschenswert, die Haare stets in derselben Richtung zu glätten, wie die Schuppen liegen. Hierzu kann die Glätteinrichtung eine Vorzugsarbeitsrichtung aufweisen, wobei in diesem Fall die Schwingungsrichtung des zumindest einen Glättelements nicht einstellbar sein muss. Andererseits kann mit der erfindungsgemäß optional vorgesehenen Sensoreinrichtung die Durchzugsrichtung der zu glättenden Haare bzw. Fasern erfasst werden, bspw. mittels eines Bewegungssensors, der daraufhin die Schwingungsrichtung des wenigstens einen Glättelements entsprechend anpasst, so dass ein Glätten der Haare mit entgegen der Schuppenrichtung ausgerichteter Schwingrichtung des zumindest einen Glättelements zuverlässig vermieden werden kann. Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen. In an advantageous development of the solution according to the invention, in each case at least one oscillating smoothing element is arranged on both arms of the smoothing device, which elements lie opposite one another and oscillate symmetrically or asymmetrically with respect to one another. The opposing, vibrating smoothing elements, the sweeping and thereby pulling the hair during the smoothing process are additionally reinforced, whereby the smoothness effect can be further enhanced. Here also a purely linear movement can take place, for example first a vertical movement towards the hair to be smoothed, then a movement in the direction of the hair, then a movement away from the hair and finally a movement back to the starting point, whereby a quadrilateral movement is achieved. Appropriately, a vibration direction of the at least one oscillating Glättelements is adjustable, wherein additionally or alternatively, a sensor device may be provided which detects the direction of passage of the hair / fibers to be smoothed and then aligns the vibration direction of the at least one Glättelements accordingly or adjusts. Since, in particular, an oscillation against a scaling direction of the hair to be smoothed would lead to a dull appearance of the hair, it is desirable to always smooth the hair in the same direction as the dandruff. For this purpose, the smoothing device may have a preferential working direction, in which case the direction of oscillation of the at least one smoothing element does not have to be adjustable. On the other hand, with the sensor device optionally provided according to the invention, the pulling direction of the hair or fibers to be smoothed can be detected, for example by means of a motion sensor, which then adjusts the direction of oscillation of the at least one smoothing element so that a smoothing of the hair is achieved with the oscillating direction of the hair directed against the scale direction At least one smoothing element can be reliably avoided. Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen. It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
Bevorzugte Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und wird in der nachfolgenden Beschreibung näher erläutert, wobei sich gleiche Bezugszeichen auf gleiche oder ähnliche oder funktional gleiche Bauteile beziehen. Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components.
Dabei zeigen, jeweils schematisch, Fig. 1 eine Schnittdarstellung durch eine erfindungsgemäße Glätteinrichtung, 1 shows a sectional illustration through a smoothing device according to the invention, FIG.
Fig. 2 eine Draufsicht auf einen Arm der erfindungsgemäßen Glätteinrichtung, 2 is a plan view of an arm of the smoothing device according to the invention,
Fig. 3 ein Diagramm einer Relativbewegung des Glättelements zu einer benachbarten, feststehenden Heizplatte in Abhängigkeit der Zeit. 3 shows a diagram of a relative movement of the smoothing element to an adjacent, stationary heating plate as a function of time.
Entsprechend der Fig. 1 , weist eine erfindungsgemäße Glätteinrichtung 1 zum Glätten von Fasern/Haaren 2 zwei schwenkbar aneinander gelagerte Arme 3, 4 auf, zwischen denen die zu glättenden Haare/Fasern 2 beim Glätten hindurch gezogen werden. Die Glätteinrichtung 1 kann dabei insbesondere als Haarglätter, das heißt als Straightener, ausgebildet sein. Erfindungsgemäß weist nun die Glätteinrichtung 1 an wenigstens einem der Arme 3, 4, hier an beiden Armen 3, 4 zumindest ein schwingendes Glättelement 5, 6 auf, das derart schwingt, dass beim Durchziehen der zu glättenden Haare/Fasern 2 zumindest einzelne Stellen der Haare/Fasern 2 mehrfach überstrichen und dadurch mehrfach geglättet werden. Die Schwingung des zumindest einen Glättelements 5, 6 kann dabei elliptisch oder rund sein, wobei eine elliptische Schwingungsbewegung/-richtung gemäß der Fig. 1 mit dem Bezugszeichen 7 bezeichnet ist. Die Schwingungsbewegung/- richtung 7 des zumindest einen Glättelements 5, 6 kann aber auch eckig, insbesondere viereckig sein. In diesem Fall erfolgt dann eine rein lineare Bewegung, beispielsweise zuerst eine vertikale Bewegung auf das/die zu glättende Haar/Faser 2 zu, dann eine Bewegung entgegen der Durchzugsrichtung 9, dann eine Bewegung vom Haar 2 weg und abschließend eine Bewegung zurück zum Ausgangspunkt, das heißt in Durchzugsrichtung 9, wodurch die Viereckbewegung erreicht wird. According to FIG. 1, a smoothing device 1 according to the invention for smoothing fibers / hairs 2 has two arms 3, 4 pivotably mounted on one another, between which the hairs / fibers 2 to be smoothed are pulled when smoothing. The smoothing device 1 can be designed in particular as a hair straightener, that is, as Straightener. According to the invention, the smoothing device 1 now has on at least one of the arms 3, 4, here at both arms 3, 4, at least one oscillating smoothing element 5, 6 which oscillates in such a way that at least individual points of the hair pass through the hair / fibers 2 to be straightened / Fibers 2 are repeatedly painted over and thus smoothed several times. The oscillation of the at least one smoothing element 5, 6 may be elliptical or round, wherein an elliptical oscillation movement / direction according to FIG. 1 is designated by the reference numeral 7. The oscillation movement / direction 7 of the at least one smoothing element 5, 6 can also be angular, in particular be square. In this case, then takes place a purely linear movement, for example, first a vertical movement to the / to be smoothed hair / fiber 2, then a movement against the pulling direction 9, then a movement away from the hair 2 and finally a movement back to the starting point, that is in the direction of passage 9, whereby the square movement is achieved.
Bei der gemäß der Fig. 1 dargestellten Glätteinrichtung 1 sind dabei zwei sich gegenüberliegende Glättelemente 5, 6 vorgesehen, die entgegengesetzt zueinander schwingen/rotieren, wodurch ein besonders effektives Glätten der zu glättenden Haare/Fasern 2 ermöglicht wird. Die Schwingungsrichtung 7 bzw. eine Schwingungsbewegung 7 des zumindest einen Glättelements 5, 6 ist dabei gemäß einer besonders bevorzugten Ausführungsform einstellbar, so dass das Glätten von insbesondere Haaren 2 stets in Liegerichtung der Schuppen der Haare erfolgen kann, wodurch neben dem eigentlichen Glätteffekt zusätzlich ein Glanzeffekt erzielt werden kann. Würden die zu glättenden Haare 2 entgegen der Schuppenrichtung geglättet, so würden diese zwar geglättet, wegen der dabei aufstehenden Schuppen wäre jedoch ein stumpfes Aussehen die Folge, was nicht erwünscht ist. In the case of the smoothening device 1 shown in FIG. 1, two opposing smoothing elements 5, 6 are provided which oscillate / rotate in opposite directions, thereby enabling a particularly effective smoothing of the hairs / fibers 2 to be smoothed. The oscillation direction 7 or an oscillation movement 7 of the at least one smoothing element 5, 6 is adjustable according to a particularly preferred embodiment, so that the smoothing of hair in particular 2 can always be done in the lying direction of the scales of the hair, which in addition to the actual smoothness effect additionally a gloss effect can be achieved. If the hairs 2 to be smoothed were smoothed against the direction of the scaling, they would indeed be smoothed, but because of the dandruff that would arise, a dull appearance would result, which is not desirable.
Bei der gemäß der Fig. 1 dargestellten Glätteinrichtung 1 sind die beiden sich gegenüberliegenden Glättelemente 5, 6 zugleich als Heiz-/Kühlplatte ausgebildet, wobei selbstverständlich auch denkbar ist, zumindest ein Glättelement 5, 6 zusätzlich zu einer separaten Heiz-/Kühlplatte 8 an einem der Arme 3, 4 der Glätteinrichtung 1 vorgesehen wird, wie dies bspw. gemäß der Fig. 2 dargestellt ist. Bei der Glätteinrichtung 1 gemäß der Fig. 2 ist dabei eine mittige Heiz-/Kühlplatte 8 mit zwei benachbart dazu angeordneten Glättelementen 5, 6 vorgesehen. 1, the two opposing smoothing elements 5, 6 are at the same time designed as a heating / cooling plate, which of course is also conceivable, at least one smoothing element 5, 6 in addition to a separate heating / cooling plate 8 at one the arms 3, 4 of the smoothing device 1 is provided, as shown, for example, according to FIG. 2. In the case of the smoothing device 1 according to FIG. 2, a central heating / cooling plate 8 with two smoothing elements 5, 6 arranged adjacent thereto is provided.
Betrachtet man nochmals die Fig. 1 , so kann man erkennen, dass die von den schwingenden Glättelementen 5, 6 auf die zu glättenden Haare/Fasern 2, 3 ausgeübte Kraft entgegen einer Durchzugsrichtung 9 der Haare/Fasern 2 verläuft. Hierdurch kann während des Glättens ein Ziehen und ein mehrfach Überstreichen der zu glättenden Haare/Fasern 2 erzielt werden. Looking again at FIG. 1, it can be seen that the force exerted by the oscillating smoothing elements 5, 6 on the hairs / fibers 2, 3 to be smoothed runs counter to a pulling direction 9 of the hairs / fibers 2. In this way, during the smoothing, a pulling and a multiple sweeping of the hair / fibers to be smoothed 2 can be achieved.
Sind an beiden Armen 3, 4 Glättelemente 5, 6 angeordnet, so können die sich nicht nur gegenüberliegen, wie dies gemäß der Fig. 1 dargestellt ist, sondern sie können zudem symmetrisch oder unsymmetrisch zueinander schwingen/rotieren. Denkbar ist selbstverständlich auch das Anordnen von mehreren Glättelementen 5, 6 je Arm 3, 4. Auch ist denkbar, dass zumindest eines der Glättelemente 5, 6 als Bürste ausgebildet ist und dabei schwingende Borsten aufweist. Um die zu glättenden Haare 2 stets in der gewünschten Vorzugsrichtung glätten zu können, kann die erfindungsgemäße Glätteinrichtung 1 lediglich eine einzige, vorgegebene Arbeitsrichtung aufweisen oder aber eine Sensoreinrichtung 10, die die Durchzugsrichtung 9 der zu glättenden Haare/Fasern 2 erkennt und daraufhin die Schwingungsrichtung/Schwingungsbewegung 7 des wenigsten einen Glättelements 5, 6 entsprechend einstellt. Die Sensoreinrichtung 10 kann dabei bspw. einen Bewegungssensor 12 aufweisen. Zur Erzeugung der Schwingungen des zumindest einen Glättelements 5, 6 kann zumindest ein Schwingungserreger 1 1 vorgesehen sein, der das zumindest eine Glättelement 5, 6 in Schwingung versetzt. Der zumindest eine Schwingungserreger 1 1 kann dabei bspw. ein Piezoelement, eine Motor mit einer Unwucht, einen Elektromagneten oder ein elektroaktives Material, insbesondere ein Polymer, aufweisen. Insbesondere bei einer schwingenden Bürste könnten die einzelnen Borsten dieser Bürste aus einem elektroaktiven Polymer ausgebildet sein. Are on both arms 3, 4 smoothing elements 5, 6 arranged so they can not only be opposite, as shown in FIG. 1, but they can also oscillate / rotate symmetrically or asymmetrically. It is of course also conceivable to arrange a plurality of smoothing elements 5, 6 per arm 3, 4. It is also conceivable that at least one of the smoothing elements 5, 6 is formed as a brush and thereby has oscillating bristles. To smooth the hair to be smoothed 2 always in the desired preferred direction, the smoothing device 1 according to the invention may have only a single, predetermined working direction or a sensor device 10 which detects the direction of passage 9 of the hair / fibers to be smoothed 2 and then the direction of vibration / Oscillation 7 of at least one smoothing element 5, 6 sets accordingly. The sensor device 10 may have, for example, a motion sensor 12. To generate the vibrations of the at least one smoothing element 5, 6, at least one vibration exciter 1 1 can be provided, which sets the at least one smoothing element 5, 6 in vibration. The at least one vibration exciter 1 1 may, for example, a piezoelectric element, a motor with an imbalance, an electromagnet or an electroactive material, in particular a polymer having. Especially with a vibrating brush, the individual bristles of this brush could be formed of an electroactive polymer.
Betrachtet man die Fig. 3, auf der auf der Abszisse die Zeit t und auf der Ordinate ein relativer Überstand s des Glättelements 5, 6 zu einer benachbarten Heiz-/Kühlplatte 8 aufgetragen ist, so kann man erkennen, dass zwischen der Zeit t0 und t-ι das Glättelement 5, 6 über die Heiz-/Kühlplatte 8 übersteht bzw. vorsteht und dadurch die zu glättenden Haare/Fasern 2 zwischen den Armen 3,4 der Glätteinrichtung 1 bremst und den Glätteffekt verstärkt. Zwischen der Zeit t-ι und t2 befindet sich das Glättelement 5, 6 auf einem Niveau unterhalb der Heiz-/Kühlplatte 8, wodurch ein freies Gleiten der zu glättenden Haare/Fasern 2 auf der Heiz-/Kühlplatte 8 erfolgen kann. Ab dem Zeitpunkt t2 steht das Glättelement 5, 6 wieder über die Heiz-/Kühlplatte 8 vor und bremst dadurch die Glätteinrichtung 1 ab bzw. verstärkt den Glätteffekt. Die Form der gezeichneten Kurve kann dabei beliebig sein und insbesondere auch über eine spezielle Steuereinrichtung eingestellt werden. If one looks at FIG. 3, on which the time t is plotted on the abscissa and a relative projection s of the smoothing element 5, 6 on an ordinate is plotted to an adjacent heating / cooling plate 8, it can be seen that between the time t 0 and t-ι the smoothing element 5, 6 projects beyond the heating / cooling plate 8 and protrudes and thereby slows down the hair / fibers to be smoothed 2 between the arms 3.4 of the smoothing device 1 and strengthens the smoothness effect. Between the time t- 1 and t 2 , the smoothing element 5, 6 is at a level below the heating / cooling plate 8, whereby a free sliding of the hair / fibers to be smoothed 2 on the heating / cooling plate 8 can take place. From time t 2 , the smoothing element 5, 6 protrudes again over the heating / cooling plate 8 and thereby brakes the smoothing device 1 or enhances the smoothness effect. The shape of the drawn curve can be arbitrary and in particular also be set via a special control device.
Mit der erfindungsgemäßen Glätteinrichtung 1 ist ein besonders effektives und gleichzeitig schonendes Glätten von Haaren/Fasern 2 möglich, da diese bei einem einzigen Glättvorgang mehrmals überstrichen und dadurch mehrmals geglättet werden. Zudem kann durch den reduzierten Wärmeeintrag das schonende Glätten unterstützt werden. With the smoothing device 1 according to the invention a particularly effective and at the same time gentle straightening of hair / fibers 2 is possible, since these are in a single Smoothing process is repeated several times and thus smoothed several times. In addition, the gentle smoothing can be supported by the reduced heat input.
