Definitions
- the invention relates to a hair supplement with hair that is aligned parallel to one another at its upper ends in a main direction and embedded and anchored in a plastic matrix, with a carrier tape running transversely to the main direction, on the front of which the plastic matrix is fastened, wherein the plastic matrix extends in the main direction essentially over the full width of the carrier tape and is covered on its outside facing away from the carrier tape with a matt covering layer, and with an adhesive layer covering the back of the carrier tape, which is designed to adhere the carrier tape to natural hair To attach the device of the hair supplement device. Furthermore, the invention relates to a method for producing such a device for hair supplement.
- a device for hair supplement with the features of the type described above, which corresponds to the preamble of independent claim 1, is from the DE 20 2005 010 845 U1 known.
- this known device for hair extension a large number of hairs are attached to a carrier tape, which is at the same time designed as an adhesive tape around the Attach device to natural hair of a wearer.
- the parallel, parallel hair is glued to the carrier tape over its entire width on one side.
- the hair is anti-hygroscopic sealed where it is glued to the carrier tape.
- such a seal ensures that its hygroscopic properties are suppressed, on the basis of which there is a risk of the hair becoming detached from its adhesion to the carrier tape as a result of the influence of moisture.
- a plastic matrix is formed in the known device for hair supplementation, in which the individual hairs are embedded and anchored with their upper ends.
- the plastic matrix On its side facing away from the carrier tape, the plastic matrix is covered with a matt and translucent covering layer, so that the plastic matrix of the device remains optically inconspicuous.
- the carrier tape which is designed as an adhesive tape, has an adhesive layer on its rear side facing away from the plastic matrix in which the hair is anchored, for sticking to the natural hair of the carrier. This adhesive layer, like the plastic matrix, extends over the entire surface of the carrier tape.
- the plastic matrix represents an optical disadvantage of the known hair extension device. That is, it is noticeable as soon as it is exposed.
- the fact that the known device for hair supplementation is exposed is relatively common when the known device is attached by its wearer or by untrained personnel.
- a hair extension which has hairs which are fastened at their upper ends in a solidified polymer, the ends of the hairs being retained in the polymer over a partial length of the hairs.
- the solidified polymer is attached to a substrate on its rear side.
- the substrate can be another solidified polymer.
- the width of the substrate is larger in a main direction of the hair than the width of the solidified polymer in which the hair is attached. The larger width of the substrate makes it easier to attach the hair extension to the natural hair of its wearer.
- the anchoring of the hair over a short length in the solidified polymer and the correspondingly smaller surface of the polymer are less noticeable. However, there is a high probability that the unnatural substrate will show through.
- the substrate is formed at the same time as the polymer, the further polymer of the substrate being able to adhere to and between the hairs. So that the substrate is not directly to the outside shines through, it is covered beneath the narrower solidified polymer with hair that is only anchored in the narrower solidified polymer and runs freely underneath over the substrate.
- a hair band with a strip-shaped support structure and with a plurality of hairs which protrude from the support structure in a main direction transverse to the main direction of extension of the support structure. Ends of the hair fixed to the support structure pass through an elastic film and are glued to the back of the film. The hair pierced by the elastic film is shortened to a few millimeters on the back of the film so that it does not overlap, and is fixed to the support structure only by gluing to the film. On the back of the film, the upper ends of the hair embedded in the adhesive are covered with a covering layer. An adhesive layer is provided on the back of the entire carrier structure and is provided with a removable protective layer.
- the adhesive layer itself can also be removable so that it can be replaced if it has become inactive, for example due to the action of hair care or washing agents. If this well-known hair band is glued to the hair of a wearer, it is particularly inconspicuous because its hair protrudes individually from the film, which gives the impression of a natural scalp. However, the production of the known hair band is much more complex than that of the device for hair extension according to the DE 20 2005 010 845 U1 .
- the hair band consists of two partial hair bands with their own adhesive layers on the back of their carrier tapes, which are only partially overlapped in the main direction of the hair using the adhesive tape of the front partial hair band, the front partial hair band being arranged higher in the main direction than the rear partial hair band.
- a hair band is known in which the hair is embedded in a plurality of layers spaced apart in the thickness direction in a plastic matrix. In all layers, the hair extends across the full width of the plastic matrix from its upper end to its lower end. Openings are formed in the plastic matrix forming the hair in order to fasten this known hair band.
- a hair extension device in which several hair bands are glued to the front of a mechanical fastening device which is provided on the back with felt-shaped fastening elements. All of the hair bands extend with their carrier bands and adhesive layers over the entire width of the fastening device in the main direction of the hair.
- the device according to the invention a combination of those from the US 2017/0065014 A1 known hair extension with the from the DE 20 2005 010 845 U1 Known device for hair extension see by as a substrate for the polymer in which the ends of the hair of the hair extension after the US 2017/0065014 A1 are embedded, the device for hair extension after the DE 20 2005 010 845 U1 is used.
- the device according to the invention comprises two groups of hair, that of the first hair, the ends of which are embedded and anchored across the width of the carrier tape in the first plastic matrix and correspondingly emerge at the lower edge of the carrier tape, and that of the second hair, the ends of which are in the are embedded and anchored over no more than half the width of the carrier tape at the upper edge of the carrier tape and which run freely underneath over the first covering layer that closes the first plastic matrix.
- the first hair already conceals the carrier tape as well as the one from the DE 20 2005 010 845 U1 known device for hair supplement.
- the second hair further camouflages the carrier tape due to its essentially free course.
- the second plastic matrix in which the ends of the second hair are embedded and anchored, preferably extends in the main direction over no more than a third of the width of the Carrier tape so that the width of the front second plastic matrix that is visible from the outside is comparatively small.
- the second plastic matrix remains particularly inconspicuous if it is provided with a matt second covering layer on its outside facing away from the carrier tape.
- this matt second covering layer can comprise a covering strip.
- This masking tape can provide the desired matt surface of the respective plastic matrix, and it can be embedded in the plastic of the respective plastic matrix, that is, infiltrated by this plastic. The latter applies in particular to a masking tape formed on the basis of fibers, such as a fabric or a gauze.
- first and / or second plastic matrix and its possible covering layer are transparent or at least translucent from the outside facing away from the carrier tape to the hair, so that they reveal the embedded ends of the hair, this also contributes to the optical unobtrusiveness of the device according to the invention for hair supplement.
- the second hairs running below the second plastic matrix in the main direction over the first covering layer of the first plastic matrix are in particular not glued on one side to the first plastic matrix or its covering layer, but rather they run freely over the first covering layer, so that they move away from the like natural hair can remove the first plastic matrix.
- the second plastic matrix extends in the main direction over 2 to 6 or preferably 2.5 to 4 mm, while the first plastic matrix and the carrier tape in the main direction typically extend over 5 to 15 mm and preferably over 6 to 12 mm.
- the hair of the hair-supplementing device according to the invention can be divided approximately equally between the first and the second hair.
- the second hair can thus make up 30 to 70% of all hair of the device.
- the second hair preferably comprises 45 to 60%, ie approximately half or a little more, of all the hair of the device in order to achieve a particularly unobtrusive overall visual impression.
- first and second hairs are embedded and anchored in the first and second plastic matrix, they are anti-hygroscopically sealed by the first and second plastic matrix.
- this seal ensures that their hygroscopic properties are suppressed, due to which there is a risk of the hair becoming detached from its anchoring in the respective plastic matrix as a result of the influence of moisture.
- the second plastic matrix preferably extends transversely to the main direction as far as the carrier tape ends of the carrier tape and up to the matrix ends of the first plastic matrix.
- the carrier tape, the first plastic matrix and the second plastic matrix preferably have the same dimensions transverse to the main direction.
- the typical length of the carrier tape between its carrier tape ends in this direction transverse to the main direction is 10 to 50 mm. This length is preferably 15 to 40 mm, for example approximately 30 mm.
- the carrier tape, the first plastic matrix and the second plastic matrix can have a predetermined kink at half the length of the carrier tape transversely to the main direction, at which a material cross section of the carrier tape and / or the first plastic matrix and / or the second plastic matrix is transverse to the Main areas adjacent areas is reduced by at least 10%.
- This predetermined kinking point facilitates the one-handed application of the device for hair supplement according to the invention by folding the carrier tape around a strand of the natural hair of the carrier of the device, which can be held with the second hand.
- the adhesive layer on the back of the carrier tape can be covered on its outside facing away from the carrier tape with a removable protective film. With this protective film, the device can in turn be removably adhered to any other similar devices on a self-adhesive product carrier.
- the protective film can be divided into two sections transversely to the main direction in order to facilitate its removal from the adhesive layer when the carrier tape with the protective film is bent outward around the main direction.
- a first adhesive layer is applied to a front side of a carrier tape. Then first hairs, which are aligned parallel to one another at their upper ends in a main direction, are placed on the first adhesive layer and covered with a second adhesive layer, which in turn is covered with a first masking tape.
- a rear side of the carrier tape is covered with a third adhesive layer, which is designed to attach the carrier tape to natural hair of a wearer of the device for hair supplementation.
- a fourth adhesive layer is applied to the masking tape, the fourth adhesive layer only covering the upper region of the carrier tape and in the main direction over no more than half the width of the Carrier tape extends.
- Second hairs which are aligned parallel to one another at their upper ends in the main direction, are placed on the fourth adhesive layer and covered with a fifth adhesive layer.
- the previous drying of the second adhesive layer prevents the second hair below the second plastic matrix formed from the fourth and fifth adhesive layers from sticking to the first plastic matrix formed from the first and second adhesive layers.
- All of the adhesive layers mentioned here can be applied to their respective substrate in the form of a single layer, but independently of one another in the form of several partial layers.
- the composition of the carrier tape can match that of the first masking tape, but can also be made stronger.
- the third adhesive layer can be covered with a removable protective film and / or the fifth adhesive layer with a second masking tape.
Description
Die Erfindung betrifft bezieht sich auf eine zur Haarergänzung mit Haaren, die an ihren oberen Enden in einer Hauptrichtung parallel zueinander ausgerichtet und in einer Kunststoffmatrix eingebettet und verankert sind, mit einem quer zu der Hauptrichtung verlaufenden Trägerband, auf dessen Vorderseite die Kunststoffmatrix befestigt ist, wobei sich die Kunststoffmatrix in der Hauptrichtung im Wesentlichen über die volle Breite des Trägerbands erstreckt und auf ihrer dem Trägerband abgekehrten Außenseite mit einer matten Abdeckschicht abgedeckt ist, und mit einer die Rückseite des Trägerbands bedeckenden Klebstoffschicht, die dazu ausgebildet ist, das Trägerband an natürlichen Haaren eines Trägers der Vorrichtung zur Haarergänzung zu befestigen. Weiterhin bezieht sich die Erfindung auf ein Verfahren zur Herstellung einer derartigen Vorrichtung zur Haarergänzung.The invention relates to a hair supplement with hair that is aligned parallel to one another at its upper ends in a main direction and embedded and anchored in a plastic matrix, with a carrier tape running transversely to the main direction, on the front of which the plastic matrix is fastened, wherein the plastic matrix extends in the main direction essentially over the full width of the carrier tape and is covered on its outside facing away from the carrier tape with a matt covering layer, and with an adhesive layer covering the back of the carrier tape, which is designed to adhere the carrier tape to natural hair To attach the device of the hair supplement device. Furthermore, the invention relates to a method for producing such a device for hair supplement.
Mit einer derartigen Vorrichtung zur Haarergänzung kann die Anzahl der natürlichen Haare des Trägers vergrößert werden. Es ist auch eine Verlängerung der natürlichen Haare des Trägers möglich. In diesem Zusammenhang spricht man auch von einer Hair Extension. Weiterhin können mit den Haaren der Vorrichtung zur Haarergänzung farbliche Kontraste gegenüber den natürlichen Haaren ihres Trägers hergestellt werden.With such a device for hair supplementation, the number of natural hairs of the wearer can be increased. An extension of the wearer's natural hair is also possible. In this context one speaks of a hair extension. Furthermore, the hair of the device for hair supplementation can be used to produce color contrasts with the natural hair of its wearer.

Trotz ihrer matten transluzenten Abdeckung stellt die Kunststoffmatrix einen optischen Nachteil der bekannten Vorrichtung zur Haarverlängerung dar. Das heißt, sie fällt, sobald sie frei liegt, in unerwünschter Weise auf. Dass die bekannte Vorrichtung zur Haarergänzung frei liegt, ergibt sich relativ häufig, wenn die bekannte Vorrichtung von ihrem Träger selbst oder durch nicht geschultes Personal angebracht wird.Despite its matt translucent covering, the plastic matrix represents an optical disadvantage of the known hair extension device. That is, it is noticeable as soon as it is exposed. The fact that the known device for hair supplementation is exposed is relatively common when the known device is attached by its wearer or by untrained personnel.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Haarergänzung, die kostengünstig herstellbar ist und dennoch unauffällig bleibt, selbst wenn sie von einem Laien wie dem Träger der Vorrichtung selbst an seinen natürlichen Haaren angebracht wird, sowie ein Verfahren zu ihrer Herstellung aufzuzeigen.The invention has for its object to provide a device for hair supplement that is inexpensive to manufacture and yet remains inconspicuous, even if it is attached to his natural hair by a layperson such as the wearer of the device itself, and a method for its production.
Die Aufgabe der Erfindung wird durch eine Vorrichtung zur Haarergänzung mit den Merkmalen des unabhängigen Patentanspruchs 1 und durch ein Verfahren zu ihrer Herstellung mit den Merkmalen des unabhängigen Patentanspruchs 12 gelöst. Bevorzugte Ausführungsformen der erfindungsgemäßen Vorrichtung sind in den abhängigen Patentansprüchen 2 bis 11 definiert. Der abhängige Patentanspruch 13 betrifft eine bevorzugte Ausführungsform des erfindungsgemäßen Verfahrens.The object of the invention is achieved by a device for hair supplementation with the features of
Eine erfindungsgemäße Vorrichtung zur Haarergänzung weist neben ersten Haaren, die an ihrem oberen Ende in einer Hauptrichtung parallel zueinander ausgerichtet und in einer ersten Kunststoffmatrix eingebettet und verankert sind, einem quer zur der Hauptrichtung verlaufenden Trägerband, auf dessen Vorderseite die erste Kunststoffmatrix befestigt ist, wobei sich die erste Kunststoffmatrix in der Hauptrichtung im Wesentlichen über die volle Breite des Trägerbands erstreckt und auf ihrer dem Trägerband abgekehrten Außenseite mit einer ersten matten Abdeckschicht abgedeckt ist, und einer die Rückseite des Trägerbands bedeckenden Klebstoffschicht, die dazu ausgebildet ist, das Trägerband an natürlichen Haaren eines Trägers der Vorrichtung zur Haarergänzung zu befestigen, zweite Haare auf, die an ihren oberen Enden in der Hauptrichtung parallel zueinander ausgerichtet und in einer zweiten Kunststoffmatrix eingebettet und verankert sind, wobei die zweite Kunststoffmatrix an einem oberen Rand des Trägerbands auf der ersten matten Abdeckschicht angeordnet ist, wobei sich die zweite Kunststoffmatrix in der Hauptrichtung über nicht mehr als die Hälfte der Breite des Trägerbands erstreckt und wobei die Haare unterhalb der zweiten Kunststoffmatrix in der Hauptrichtung frei über die erste matte Abdeckschicht hinweg verlaufen. Die ersten und die zweiten Haare enden in der Hauptrichtung mit der ersten oder zweiten Kunststoffmatrix am oberen Rand des Trägerbands. Das heißt, die Haare sind über die gesamte Erstreckung der jeweiligen Kunststoffmatrix in der Hauptrichtung in dieser verankert.In addition to the first hair, which is aligned parallel to one another at its upper end in a main direction and embedded and anchored in a first plastic matrix, a device for hair supplementation according to the invention has a carrier tape running transversely to the main direction, on the front side of which the first plastic matrix is fastened, whereby the first plastic matrix extends in the main direction essentially over the full width of the carrier tape and is covered on its outside facing away from the carrier tape with a first matt covering layer, and an adhesive layer covering the back of the carrier tape, which is designed to adhere the carrier tape to natural hair Carrier of the device for hair supplement to attach, second hair, which is aligned at their upper ends in the main direction parallel to each other and in a second plastic matrix are embedded and anchored, the second plastic matrix being arranged on an upper edge of the carrier tape on the first matt covering layer, the second plastic matrix extending in the main direction no more than half the width of the carrier tape and the hair below the second plastic matrix run freely in the main direction over the first matt cover layer. The first and the second hair end in the main direction with the first or second plastic matrix at the upper edge of the carrier tape. This means that the hair is anchored in the main direction in the main direction over the entire extent of the respective plastic matrix.
Retrospektiv mag man in der erfindungsgemäßen Vorrichtung eine Kombination der aus der
Vorzugsweise erstreckt sich die zweite Kunststoffmatrix, in der die Enden der zweiten Haare eingebettet und verankert sind, in der Hauptrichtung über nicht mehr als ein Drittel der Breite des Trägerbands, so dass die von außen sichtbare Breite der vorderen zweiten Kunststoffmatrix vergleichsweise klein ist.The second plastic matrix, in which the ends of the second hair are embedded and anchored, preferably extends in the main direction over no more than a third of the width of the Carrier tape so that the width of the front second plastic matrix that is visible from the outside is comparatively small.
Besonders unauffällig bleibt die zweite Kunststoffmatrix, wenn sie auf ihrer dem Trägerband abgekehrten Außenseite mit einer matten zweiten Abdeckschicht versehen ist. Diese matte zweite Abdeckschicht kann ebenso wie die matte erste Abdeckschicht der ersten Kunststoffmatrix ein Abdeckband umfassen. Dieses Abdeckband kann die gewünschte matte Oberfläche der jeweiligen Kunststoffmatrix bereitstellen, und es kann in den Kunststoff der jeweiligen Kunststoffmatrix eingebettet sein, das heißt von diesem Kunststoff infiltriert sein. Letzteres gilt insbesondere bei einem auf der Basis von Fasern ausgebildeten Abdeckband, wie einem Gewebe oder einer Gaze.The second plastic matrix remains particularly inconspicuous if it is provided with a matt second covering layer on its outside facing away from the carrier tape. Like the matt first covering layer of the first plastic matrix, this matt second covering layer can comprise a covering strip. This masking tape can provide the desired matt surface of the respective plastic matrix, and it can be embedded in the plastic of the respective plastic matrix, that is, infiltrated by this plastic. The latter applies in particular to a masking tape formed on the basis of fibers, such as a fabric or a gauze.
Wenn die erste und/oder zweite Kunststoffmatrix und ihre etwaige vorhandene Abdeckschicht von ihrer dem Trägerband abgekehrten Außenseite bis zu den Haaren hin transparent oder zumindest transluzent sind, so dass sie die eingebetteten Enden der Haare erkennen lassen, trägt auch dies zur optischen Unauffälligkeit der erfindungsgemäßen Vorrichtung zur Haarergänzung bei.If the first and / or second plastic matrix and its possible covering layer are transparent or at least translucent from the outside facing away from the carrier tape to the hair, so that they reveal the embedded ends of the hair, this also contributes to the optical unobtrusiveness of the device according to the invention for hair supplement.
Die unterhalb der zweiten Kunststoffmatrix in der Hauptrichtung über die erste Abdeckschicht der ersten Kunststoffmatrix hinweg verlaufenden zweiten Haare sind insbesondere nicht einseitig an die erste Kunststoffmatrix oder deren Abdeckschicht angeklebt, sondern sie verlaufen frei über die erste Abdeckschicht, so dass sie sich wie natürliche Haare von der ersten Kunststoffmatrix weg entfernen können.The second hairs running below the second plastic matrix in the main direction over the first covering layer of the first plastic matrix are in particular not glued on one side to the first plastic matrix or its covering layer, but rather they run freely over the first covering layer, so that they move away from the like natural hair can remove the first plastic matrix.
Typischerweise erstreckt sich die zweite Kunststoffmatrix in der Hauptrichtung über 2 bis 6 oder vorzugsweise 2,5 bis 4 mm, während sich die erste Kunststoffmatrix und das Trägerband in der Hauptrichtung typischerweise über 5 bis 15 mm und vorzugsweise über 6 bis 12 mm erstrecken.Typically, the second plastic matrix extends in the main direction over 2 to 6 or preferably 2.5 to 4 mm, while the first plastic matrix and the carrier tape in the main direction typically extend over 5 to 15 mm and preferably over 6 to 12 mm.
Die Haare der erfindungsgemäßen Vorrichtung zur Haarergänzung können zu etwa gleichen Teilen auf die ersten und die zweiten Haare aufgeteilt sein. So können die zweiten Haare 30 bis 70 % aller Haare der Vorrichtung ausmachen. Vorzugsweise umfassen die zweiten Haare 45 bis 60 %, d. h. etwa die Hälfte oder etwas mehr aller Haare der Vorrichtung, um einen besonders unauffälligen optischen Gesamteindruck zu erzielen.The hair of the hair-supplementing device according to the invention can be divided approximately equally between the first and the second hair. The second hair can thus make up 30 to 70% of all hair of the device. The second hair preferably comprises 45 to 60%, ie approximately half or a little more, of all the hair of the device in order to achieve a particularly unobtrusive overall visual impression.
Dort, wo die ersten und zweiten Haare in der ersten bzw. zweiten Kunststoffmatrix eingebettet und verankert sind, sind sie durch die erste bzw. zweite Kunststoffmatrix anti-hygroskopisch versiegelt. Diese Versiegelung sorgt bei Haaren aus Echthaar dafür, dass ihre hygroskopischen Eigenschaften unterdrückt werden, aufgrund derer die Gefahr eines Loslösens der Haare aus ihrer Verankerung in der jeweiligen Kunststoffmatrix infolge des Einflusses von Feuchtigkeit besteht.Where the first and second hairs are embedded and anchored in the first and second plastic matrix, they are anti-hygroscopically sealed by the first and second plastic matrix. In the case of human hair, this seal ensures that their hygroscopic properties are suppressed, due to which there is a risk of the hair becoming detached from its anchoring in the respective plastic matrix as a result of the influence of moisture.
Vorzugsweise erstreckt sich die zweite Kunststoffmatrix quer zu der Hauptrichtung bis an die Trägerbandenden des Trägerbands und bis an die Matrixenden der ersten Kunststoffmatrix. Anders gesagt weisen das Trägerband, die erste Kunststoffmatrix und die zweite Kunststoffmatrix vorzugsweise gleiche Ausdehnungen quer zu der Hauptrichtung auf. Dabei beträgt die typische Länge des Trägerbands zwischen seinen Trägerbandenden in dieser Richtung quer zu der Hauptrichtung 10 bis 50 mm. Vorzugsweise beträgt diese Länge 15 bis 40 mm, also beispielsweise etwa 30 mm.The second plastic matrix preferably extends transversely to the main direction as far as the carrier tape ends of the carrier tape and up to the matrix ends of the first plastic matrix. In other words, the carrier tape, the first plastic matrix and the second plastic matrix preferably have the same dimensions transverse to the main direction. The typical length of the carrier tape between its carrier tape ends in this direction transverse to the main direction is 10 to 50 mm. This length is preferably 15 to 40 mm, for example approximately 30 mm.
Bei der erfindungsgemäßen Vorrichtung können das Trägerband, die erste Kunststoffmatrix und die zweite Kunststoffmatrix auf halber Länge des Trägerbands quer zu der Hauptrichtung eine Sollknickstelle aufweisen, an der ein Materialquerschnitt des Trägerbands und/oder der ersten Kunststoffmatrix und/oder der zweiten Kunststoffmatrix gegenüber quer zu der Hauptrichtung angrenzenden Bereichen um mindestens 10 % reduziert ist. Diese Sollknickstelle erleichtert das einhändige Anbringen der erfindungsgemäßen Vorrichtung zur Haarergänzung unter Zusammenfalten des Trägerbands um eine Strähne des natürlichen Haars des Trägers der Vorrichtung, das dabei mit der zweiten Hand gehalten werden kann.In the device according to the invention, the carrier tape, the first plastic matrix and the second plastic matrix can have a predetermined kink at half the length of the carrier tape transversely to the main direction, at which a material cross section of the carrier tape and / or the first plastic matrix and / or the second plastic matrix is transverse to the Main areas adjacent areas is reduced by at least 10%. This predetermined kinking point facilitates the one-handed application of the device for hair supplement according to the invention by folding the carrier tape around a strand of the natural hair of the carrier of the device, which can be held with the second hand.
Die Klebstoffschicht auf der Rückseite des Trägerbands kann auf ihrer dem Trägerband abgekehrten Außenseite mit einer abnehmbaren Schutzfolie abgedeckt sein. Mit dieser Schutzfolie kann die Vorrichtung wiederum abziehbar auf jeden anderen gleichartigen Vorrichtungen auf einen selbstklebenden Produktträger aufgeklebt sein.The adhesive layer on the back of the carrier tape can be covered on its outside facing away from the carrier tape with a removable protective film. With this protective film, the device can in turn be removably adhered to any other similar devices on a self-adhesive product carrier.
Etwa auf halber Länge des Trägerbands kann die Schutzfolie quer zu der Hauptrichtung in zwei Abschnitte unterteilt sein, um ihr Abnehmen von der Klebstoffschicht zu erleichtern, wenn das Trägerband mit der Schutzfolie nach außen um die Hauptrichtung gebogen wird.Approximately half the length of the carrier tape, the protective film can be divided into two sections transversely to the main direction in order to facilitate its removal from the adhesive layer when the carrier tape with the protective film is bent outward around the main direction.
Bei einem erfindungsgemäßen Verfahren zur Herstellung einer erfindungsgemäßen Vorrichtung zur Haarergänzung wird eine erste Klebstoffschicht auf eine Vorderseite eines Trägerbands aufgebracht. Dann werden erste Haare, die an ihren oberen Enden in einer Hauptrichtung parallel zueinander ausgerichtet sind, auf die erste Klebstoffschicht aufgelegt und mit einer zweiten Klebstoffschicht abgedeckt, die wiederum mit einem ersten Abdeckband abgedeckt wird. Eine Rückseite des Trägerbands wird im Laufe des erfindungsgemäßen Verfahrens mit einer dritten Klebstoffschicht bedeckt, die dazu ausgebildet ist, das Trägerband an natürlichen Haaren eines Trägers der Vorrichtung zur Haarergänzung zu befestigen. Nach dem Abdecken der zweiten Klebstoffschicht mit dem ersten Abdeckband und einem anschließenden Abtrocknen der zweiten Klebstoffschicht wird eine vierte Klebstoffschicht auf das Abdeckband aufgebracht, wobei sich die vierte Klebstoffschicht nur im oberen Bereich des Trägerbands und in der Hauptrichtung über nicht mehr als die Hälfte der Breite des Trägerbands erstreckt. Weiter werden zweite Haare, die an ihren oberen Enden in der Hauptrichtung parallel zueinander ausgerichtet sind, auf die vierte Klebstoffschicht aufgelegt und mit einer fünften Klebstoffschicht abgedeckt. Dabei verhindert das vorherige Abtrocknen der zweiten Klebstoffschicht, dass die zweiten Haare unterhalb der aus der vierten und fünften Klebstoffschicht ausgebildeten zweiten Kunststoffmatrix mit der aus der ersten und zweiten Klebstoffschicht ausgebildeten ersten Kunststoffmatrix verkleben. Nach dem Anordnen aller Schichten, Haare und Bänder auf dem Trägerband wird das Trägerband so zugeschnitten, dass die erfindungsgemäße Vorrichtung mit den gewünschten Abmessungen erhalten wird, wobei die Haare in der Hauptrichtung mit der ersten und zweiten Kunststoffmatrix am oberen Rand des Trägerbands enden.In a method according to the invention for producing a device for hair supplementation according to the invention, a first adhesive layer is applied to a front side of a carrier tape. Then first hairs, which are aligned parallel to one another at their upper ends in a main direction, are placed on the first adhesive layer and covered with a second adhesive layer, which in turn is covered with a first masking tape. In the course of the method according to the invention, a rear side of the carrier tape is covered with a third adhesive layer, which is designed to attach the carrier tape to natural hair of a wearer of the device for hair supplementation. After covering the second adhesive layer with the first masking tape and then drying the second adhesive layer, a fourth adhesive layer is applied to the masking tape, the fourth adhesive layer only covering the upper region of the carrier tape and in the main direction over no more than half the width of the Carrier tape extends. Second hairs, which are aligned parallel to one another at their upper ends in the main direction, are placed on the fourth adhesive layer and covered with a fifth adhesive layer. The previous drying of the second adhesive layer prevents the second hair below the second plastic matrix formed from the fourth and fifth adhesive layers from sticking to the first plastic matrix formed from the first and second adhesive layers. After arranging all the layers, hair and ribbons on the carrier tape, the carrier tape is cut so that the device according to the invention is obtained with the desired dimensions, the hair ending in the main direction with the first and second plastic matrix at the upper edge of the carrier tape.
Alle hier genannten Klebstoffschichten können in Form einer einzigen Schicht, aber unabhängig voneinander auch in Form mehrerer Teilschichten auf ihr jeweiliges Substrat aufgetragen werden. Das Trägerband kann in seiner Zusammensetzung mit dem ersten Abdeckband übereinstimmen, aber auch stärker ausgebildet sein.All of the adhesive layers mentioned here can be applied to their respective substrate in the form of a single layer, but independently of one another in the form of several partial layers. The composition of the carrier tape can match that of the first masking tape, but can also be made stronger.
Zusätzlich kann die dritte Klebstoffschicht mit einer abnehmbaren Schutzfolie und/oder die fünfte Klebstoffschicht mit einem zweiten Abdeckband abgedeckt werden.In addition, the third adhesive layer can be covered with a removable protective film and / or the fifth adhesive layer with a second masking tape.
Wie schon angedeutet wurde, können alle Schritte im Zusammenhang mit der dritten Klebstoffschicht auf der Rückseite des Trägerbands auch erst nach dem Aufbringen und etwaigen Abdecken der fünften Klebstoffschicht erfolgen.As has already been indicated, all steps in connection with the third adhesive layer on the back of the carrier tape can only take place after the fifth adhesive layer has been applied and possibly covered.
Mit der Angabe "quer zu der Hauptrichtung" wird hier immer nicht nur auf eine genau senkrechte Richtung sondern auf jede Richtung Bezug genommen, die eine wesentliche Komponente senkrecht zu der Hauptrichtung aufweist.With the specification "transversely to the main direction", reference is always made here not only to an exactly vertical direction but also to any direction which has an essential component perpendicular to the main direction.
Bei den Haaren der erfindungsgemäßen Vorrichtung zur Haarverlängerung kann es sich um Echthaare handeln, die dann in der Richtung ihres natürlichen Verlaufs von der Haarwurzel zur Haarspitze in der Hauptrichtung auszurichten sind und so von der Kunststoffmatrix weg verlaufen. Bei den Haaren kann es sich aber auch um Kunsthaare handeln, insbesondere um hochwertige Kunsthaare auf der Basis von Horn.The hair of the device for hair extension according to the invention can be real hair, which must then be aligned in the main direction in the direction of its natural course from the hair root to the hair tip and thus run away from the plastic matrix. However, the hair can also be synthetic hair, in particular high-quality synthetic hair based on horn.
