Definitions
- the present invention relates to a method of preparing hair extensions for creating hairstyles, a tool for the said method and an extension prepared by this method.
- a number of currently fashionable hairstyles require the attachment to the person's natural hair of hair extensions in, for example, the form of ponytails, plaits and the like. These extensions are attached to the natural hair and removed from it as the wearer requires.
- these known hair extensions are prepared by bonding natural hair or artificial hair (the latter will also be called hair in this text), or the like, together at one end with a small quantity of adhesive substance, usually a thermoplastic resin. This operation is performed by holding the lock of hair in the fingers of one hand; the other hand then applies a drop of heated, and therefore fluid, resin onto the ends of the hair. The hairs are then worked and twisted between the fingers to form, with the consequent immediate hardening of the resin once it has cooled, a cylinder comprising resin and hair, similar to a slubbing or roving.
- a small quantity of adhesive substance usually a thermoplastic resin.
- the hair extension is heated with a suitable tool on the roving as prepared above and joined to the natural hair, or indeed to a wig, where desired.
- the fingers tend to stick to the hair extension and the result is an irregular cylinder.
- the object of the present invention is therefore to overcome the abovementioned disadvantages.
- the present invention relates to a method of preparing hair extensions for creating hairstyles, in which a quantity of thermoplastic resin is applied in the fluid state to one end of a lock of natural or artificial hairs in order to bond them together to form a hair extension, forming a concave shell, similar in form to a fingernail, which is suitable for the subsequent accommodation in the abovementioned concavity of a lock of the wearer's own hair to which the hair extension is to be attached.
- the method according to the invention is such as to comply with work safety standards.
- a method of preparing hair extensions comprises the following steps:
- the invention additionally provides, for the preparation of hair extensions for creating hairstyles, a compressive moulding tool comprising a concave half or die and a convex half or punch, preferably made of a non-stick material with respect to the thermoplastic resin; the halves being movable towards each other to compress the end of the lock of hair in contact with the thermoplastic resin, and away from each other after compression and hardening.
- the moulding tool preferably of manual type, is made from a pair of pliers or a bench press fitted with concave and convex moulding halves.
- the tool may be equipped with motors and servocontrols allowing it to operate semi-automatically or automatically.
- the present invention also provides a hair extension for creating hairstyles produced by the method of the invention, in which the hairs of a lock are bonded at one end in a concave shell of thermoplastic resin shaped like a fingernail.
- the method of preparing hair extensions for creating hairstyles in accordance with the present invention provides for the application of a limited quantity of thermoplastic resin to one end of a lock of natural or artificial hairs in order to bond them together to form a hair extension. More precisely, a drop of thermoplastic resin, usually of the so-called "hot-melt” type (such as that marketed under the trade name Tubitrans Melt), made fluid by heating, is dropped onto the ends of the hairs of the hair extension that is to be formed, which latter is then placed on a concave surface to which the thermoplastic resin will not stick.
- a drop of thermoplastic resin usually of the so-called “hot-melt” type (such as that marketed under the trade name Tubitrans Melt)
- Tubitrans Melt tubitrans Melt
- the abovementioned concave surface is that of a die designed to engage, in a moulding operation, with a punch, the material of the latter also preferably being non-stick with respect to the thermoplastic resin, having a corresponding cylindrical surface.
- the die and punch are installed in a compressive moulding tool, which will be described later in a variety of embodiments shown in Figures 2 to 6.
- the die and the punch are movable towards each other to compress the end of the lock of hair to which the thermoplastic resin has been applied and then away from each other after compression and hardening of the resin in a concave shape.
- This concave die surface is preferably a portion of the lateral surface of a cylinder whose diameter is greater the greater the quantity of hair which the resin is to bond.
- the portion of the lateral surface of the die is bounded by two cylindrical generatrices passing through the same semicircular base.
- the hair extension is removed from the tool after the rapid cooling of the resin and its consequent hardening, and finished by limiting the length of the portion covered by the resin, as shown by way of example in Figure 1.
- the hair extension comprises a lock 1 of natural or artificial hairs, which can be straight or curly, loose or plaited, bonded at one end in a concave shell 2 consisting of hardened thermoplastic resin, roughly similar in form to a fingernail.
- This shape is highly suitable for the subsequent attachment of the resulting hair extension to a person's hair.
- the concave shell will be heated with a suitable tool and applied around a lock of the person's own hair to form a special hairstyle, e.g. a ponytail, plait or the like, to which other embellishments may also be added.
- the hair extension is removed in the conventional way by breaking up the resin-bound end with a suitable pair of pliers and applying a known liquid solvent, such as for example 90° ethyl alcohol or cosmetic acetone, to this broken up portion after which the hair extension is removed.
- a known liquid solvent such as for example 90° ethyl alcohol or cosmetic acetone
- FIG. 2 shows a first embodiment of a moulding tool for preparing a hair extension in accordance with the present invention, to which the general reference 3 is given.
- the moulding tool 3 is essentially a pair of pliers whose tips 4, 5 carry the concave moulding half or die 6 and the convex moulding half or punch 7, respectively.
- the hair extension In order to prepare the hair extension, a drop of resin, heated until fluid, is applied to the end of the lock of hair, the hair extension is then laid in the die 6, and the tips 4, 5 are brought together, closing the pliers, and, after the resin has hardened, the tips are separated again.
- the hair extension can be taken out for finishing.
- FIG. 3 shows part of a second embodiment of a moulding tool in accordance with the present invention, having the general reference 30.
- the moulding tool 30 is once again basically a pair of pliers, the tips 40, 50 of which carry the die 60 and the punch 70, respectively.
- the respective axes of symmetry (not indicated in the figure) of the die and punch 60, 70 are coincident or parallel with the axes of symmetry of the tips 40, 50 of the pliers (once again these are not indicated in the figure).
- the punch 70 is essentially cylindrical while the die 60 comprises symmetrically extended walls 61 inclined slightly outwards relative to the inner portion 62 of the die. This facilitates the placing of the end of the lock of hair in the die 60.
- the moulding operation is basically the same as for the first embodiment 3 of the tool, the only difference being the disposition of the lock of hair relative to the pliers.
- FIGS 4 and 5 show a third embodiment of a moulding tool in accordance with the present invention, under the general reference 300.
- the moulding tool 300 is basically a manual press and has a body 10 provided underneath with a clamp 11 for fixing it to a workbench (not shown).
- a hand actuated bar 13 is hinged to the body 10 between two trunnions 14.
- the bar 13 comprises a hub 15 mounted on a stationary pin 16 at the opposite end from the hand end.
- the bar 13 carries a convex half or punch 500 mounted transversely in a position such as to arrive in a moulding relationship with the concave half 400.
- the moulding operation is basically the same as that performed with the first embodiment 3 of the tool as far as the disposition of the lock of hair relative to the tool is concerned. As is obvious, productivity and convenience of work are improved because the tool does not have to be held in the operator's hand.
- FIG. 6 A fourth embodiment of the moulding tool in accordance with the present invention is shown in Figure 6 under the general reference 301.
- the moulding tool 301 is basically a manual press in which the advancing movement is provided by the operator by an arrangement similar to that usually used in a so-called sensitive drill.
- the tool 301 has a base 100 solid enough to keep it stable on a work surface and hold it in a fixed position throughout operation without the need for fixing means.
- Fixed vertically to the base 100 is a column 101, which may be a cylindrical column, supporting a rack 102.
- Mounted movably on the column 101 by two rear arms 170 and 171 that encircle the column 101 is a bracket 17.
- the stroke of the bracket 17 up and down the column 101 is limited by a shoulder 103 fastened to the column 101 in the gap between the rear arms 170 and 171 of the bracket 17.
- Sitting between the mutually confronting surfaces of the shoulder 103 and the rear arm 170 is a helical spring 18.
- An actuating lever 19, with a hand grip 20 at the end (shown partially), is hinged in a known way to the bracket 17 with a pinion (not shown) engaging with the rack 102.
- the plate 22 has integral vertical guide pins 201, 202 for the ram plate 21, and the latter has corresponding through holes for the vertical pins 201, 202.
- Fitted between the plate 22 and the ram plate 21 is a helical spring 23.
- Fixed vertically to and downwards from the ram plate 21 is a prismatic component 24, its major axis being perpendicular to the plane of the drawing paper, with a convex U-profile punch 25 in its free end.
- the plate 22 supports a prismatic component 26, its major axis similarly perpendicular to the drawing paper, with a concave die 27 of identical U profile in its free end.
- One end of the hair extension, to which the thermoplastic resin has been applied, is laid in the cavity of the concave die 27.
- the operator acting on the lever 19 against both opposing springs 18 and 23, brings the punch 25 down onto the die 27 and compresses the resin and the ends of the hairs between their respective convex and concave surfaces.
- the punch 25 is withdrawn from the die 27 by the action of the opposing springs and the hair extension is removed.
- the tool 301 in the fourth embodiment can be conveniently moved to where it is needed without time being wasted on installation.
- the punch is introduced into the die with a rectilinear motion rather than a rotary one. This makes the moulding symmetrically uniform and produces a shell of more even thickness.
- Removal from the mould is automatic because of the opposing springs, as soon as the operator releases the actuating lever 19. This reduces processing time.
- the greater length in the perpendicular direction of the die and punch enables the shell to be reduced subsequently to the desired dimension.
Abstract
