US patent No. 3,280,826 (Jenkins ) describes a multi-layered weft hair extension, obtained by folding on itself a long weft of hair connected to a thread-like element; this extension is then fastened to hair by means of clips. Other extensions applicable by means of fastening mechanical means or stitcher are known fromUS patents No. 4,830,029 (Bird );No. 5,121,761 (Meister ) andNo. 5,881,737 (Nelson ). -
US patent No. 6,135,122 (Campbell et al. ) describes a weft hair extension with a single layer, wherein the hair are kept in their position by a closely woven band provided with an adhesive layer; other extensions of this type are known fromUS patent applications No. 2001/0035192 (Townsend ); No.2006/0169296 (Gill et al. ); No.2009/0032041 (Ott ); No.2009/0120451 (Kenna ); and No.2013/0298925 (Gold ); and from International patent application No.WO 2011/036654 (Gold ). - European patent application No.
EP 2,614,736 (Lee ) describes a weft hair extension wherein hair is kept at one end thereof by a strip of plastic material (polyurethane), provided with holes for the passage of receiving hair which is used then for locking the extension thanks to the use of small fastening rings which are squeezed by means of suitable tweezers. - French patent No.
FR 2,968,520 (L'Oréal - At last,
US patent N. 8,025,065 (Gulliker ) describes a weft hair extension with a double layer: such layers fold on themselves once performed the application to host hair with knot connections, thus determining a thickening of the connection. - The forced use of hands of the known systems involves a series of problems. First of all the operator, in order to be able to perform connections perfectly, should have great experience and practice, which obviously will not be always possible. Furthermore, apart experience, it will be extremely difficult to produce connections equal therebetween: they will be mostly different, not positioned exactly on the lines provided for the thickening, with variable qualities and sizes.
- All this determines a not optimum quality of the finished work, more exposed to wear and with in reality unavoidable imperfections, a high cost as influenced by very long application time and by the not easy availability of expert operators.
- However, one of the more relevant problems in the application of this type of weft-like thickening is represented by the thickness of the hair connecting element, and this problem is particularly felt in case of multi-layered systems.
- The technical problem underlying the present invention is to provide a weft hair extension to thicken hair and a relative manufacturing method allowing to obviate the drawbacks mentioned with reference to the known art.
- Such problem is solved by a weft hair extension as specified above, comprising:
- a flat foil of hair aligned therebetween;
- a first linear connecting element formed by a strip made of thermoplastic material wherein a proximal end of hair of said flat foil is embedded;
- a second linear connecting element formed by an additional strip made of thermoplastic material arranged parallelly to said linear connecting element at a distance therefrom; and
- transversal connecting means constituted by one or more tab-like flexible elements embeddable in said strips made of thermoplastic material and arranged transversally thereto so as to connect them once embedded therein.
- The main advantage of the hair extension according to the present invention lies in the fact of allowing a quick application by using said tab-like elements as devices for anchoring the hair extension to host hair, without increasing the extension thickness.
- Furthermore, a permanent application is possible by using the thermoplastic features of the second linear connecting element.
- The method for manufacturing the weft hair extension according to the present invention comprises the steps of:
- arranging on a plane a flat foil of hair aligned therebetween;
- embedding an end of said flat foil in a first strip of thermoplastic material substantially perpendicular to said hair;
- arranging at a certain distance from said first strip a second strip made of thermoplastic material, substantially parallel thereto; and
- embedding, in said first and second strip, tab-like flexible elements by arranging them transversally to said strips to constitute a flexible connection.
- The present invention will be described hereinafter according to a preferred embodiment, provided by way of example and not for limitative purpose with reference to the enclosed drawings wherein:
-
Figures 1 to 3 show respective perspective views illustrating the first three steps of a method for manufacturing weft hair extensions; -
Figure 4 show a magnification of the half-finished extension offigure 3 ; -
Figures 5 and 6 show respective perspective views illustrating two additional steps of a method for manufacturing weft hair extensions; and -
Figure 7 shows an overall perspective view of the so-produced resulting hair extension. - By referring to figures,
figure 1 illustrates a first step of the method for manufacturing, according to the present invention, a weft hair extension wherein aflat foil 1 of straight hair is arranged on a plane, for example made of steel. - The hairs are arranged in an orderly manner, parallel therebetween, with the respective proximal ends thereof, that is those cut near the scalp, arranged to form an almost straight line. The hairs are selected to that they substantially have the same length, and in case the respective distal ends will be evened with a rectilinear cut.
- Hair can be of any type, preferably it is natural. I form a foil with almost uniform thickness, in the order of tenths of millimetre.
- In a second step (
figure 2 ), on the line corresponding to the proximal ends of hair of thefoil 1, line which identifies theproximal end 2 of the extension, afirst strip 3 made of thermoplastic material is placed, so as to soften temporarily by means of applying a predetermined temperature, for example 200°, or in case of ultrasounds. This softening allows to penetrate the hair strip, by applying a certain pressure. - The
strip 3 is made of a resin or thermoplastic rubber, possibly a refoldable material, soft to the touch. - As it is noted, the
strip 3 is arranged perpendicularly to the single hair of thefoil 1. - Therefore, the
strip 3 is pressed by a heated press 4 which softens thestrip 3 by causing the penetration of the hair distal ends of thefoil 1 in the thickness of the strip, penetration which takes place at a first face of said strip. - Once hair is embedded in the thickness of the first strip, this becomes a first linear connecting
element 3 of the hair extension. - It is to be noted that the thickness of the thermoplastic strip could be about 1 mm or even smaller.
- In order to obtain a weft hair extension with a perfectly rectilinear
proximal end 2 and a first linear connectingelement 3 with predetermined height, for example comprised between 3 and 7 mm, in a subsequent step (figure 3 ) one provides to trim the exposed margin of the connectingelement 3 by means of asuitable knife 7. - In case, even the side ends of the connecting
element 3 can be trimmed, so that the hair of thefoil 1 end exactly at such end (figure 4 ). - In a subsequent step (
figure 5 ), asecond strip 5 made of thermoplastic material, in case equal to the previous one, is arranged at a certain distance from saidfirst strip 3, substantially parallel thereto. - The distance is so as to allow the passage between the
strips - Subsequently, tab-like
flexible elements 6 are provided, in the form of small strips with length so that they can extend transversally, and then preferably perpendicularly, to thethermoplastic strips - The tab-
like elements 6 are then so arranged like a bridge between saidthermoplastic strips - The tab-
like elements 6 are made of porous material and with reduced thickness, so that they, or portions thereof, can be embedded, i.e. embeddable, with pressure within the strips made ofthermoplastic material - By way of example, the material thereof they can be formed could be gauze or organza, in particular then a tissue formed by a plain weave, for example cotton or other natural textile fibre, nylon, polyester and so on. It is to be meant that the selected material should be flexible.
- Once provided the tab-
like elements 6, the are arranged as described previously. It is to be noted that, in this step, thefoil 1 and the respective linear connectingelement 3 have been turned, so as to expose the face ofstrip 3 opposite to that therethrough the hair of thefoil 1 have been previously penetrated. - In this step, the tab-like elements are penetrated in the respective thicknesses of the two
strips distal end 2 of thefoil 1. - Once the
strips figure 6 ), the tab-like elements 6 will constitute flexible connecting means between thestrips element 5. - The manufacturing of the weft hair extension, designated with 10 in
figure 7 , will be thus ended. - Such
weft hair extension 10 then will include aflat foil 1 of hair aligned therebetween, kept together by a first linear connectingelement 3 which is formed by a strip made of thermoplastic material wherein theproximal end 2 of hair of saidflat foil 1 is embedded. It further comprises a second linear connectingelement 5 formed by an additional strip made of thermoplastic material arranged parallelly to said first linear connectingelement 3 at a distance therefrom. - The two connecting
elements flexible elements 6, preferably at least two. - They have the peculiarity of being embeddable in said strips made of thermoplastic material and they are arranged transversally thereto so as to connect them once embedded therein.
- Under "embeddable" it is meant that they are made of any shape and flexible material apt to be penetrated under pressure in a strip made of softened thermoplastic material.
- It is to be meant that they could assume a different shape from the tissue strips described previously: they could have a shape like a double T, so as to implement a greater grasp with the strips. It is further meant that the open-worked tissue is only one of the possible variants applicable to such hinge elements.
- The two strips of suitable material have the capability of keeping a fixed position once arranged between two locks of host hair covering them completely, by implementing a stable and poorly perceivable to the touch or by shaking her head, this because they adhere to the host locks by adapting to the shape and motions thereof.
- The space between the linear connecting
elements like elements 6 can be conveniently exploited for implementing the application of the extension to the receiving hair. - To the above-described weft hair extension a person skilled in the art, with the purpose of satisfying additional and contingent needs, could introduce several additional modifications and variants, all however comprised within the protective scope of the present invention, as defined by the enclosed claims.
