Group of inventions relates to the manufacture of both partial and full wigs or hair prostheses, such as replacing the missing hair in problem areas of the head, for example, when the focal alopecia. Permanent socks without removing the prosthesis from the head at night.

You know the invention of "A method of making a hairpiece", patent GB No. 1272508 published 1972-05-03, IPC A41G 3/00; A41G 3/00, where to obtain forms close to the scalp on the outer side of cloth and cloth fix solidifying mass, which preserves the shape of the fabric. However, the invention solves the other task is making measurements on the basis of which are provided with the Foundation for hair prosthesis, and not the very basis of the hair prosthesis.

Known invention "A method for making a hairpiece", patent GB No. 1217190 published 1970-12-31, IPC A41G 3/00; A41G 3/00, in which there the hair, consisting of cross-linked groups of the substrate and coated with the composition (material) rubber-based. However, the edges of the individual cross-linked groups attached silk ribbon. Mounting method groups the basics very rough, damaging the skin and not giving simulate natural hair growth. When this partial wig is a hair prosthesis and its impossible to wear a few days without taking off because it hurt the scalp.

Known invention "A rigid hollow working head for wigs", patent GB No. 1281231 published 1972-07-12, IPC 45D44/14; A45D 44/00, A41G 3/00, in which the basis for further production of partial wig made in the form of caps, with the convex parts corresponding to the head. The basis is fixed directly on the scalp in the area of problem areas, on which is placed an elastic material. However, in order partial wig kept on the problem area, use a coarse, not ergonomic material such as rubber, allowing you to shape it in accordance with a complex convex contour area and the stiffness of it form the ribs, which maintains a partial wig on his head. Such partial wig cannot be hair prosthesis as uncomfortable to wear and not imitates natural skin.

Known invention "A "capless" wig", patent GB No. 1294774 published 1972-11-01, IPC A41G 3/00; A41G 3/00; containing an edge strip and carrier strip formed by the intersection of the bearing bars. The invention allows to form the basis for wig - lining of thin, ergonomic material that mimics the skin, but to maintain the shape of the base is equipped with a coarse supporting ribs, which greatly complicate his toe on the head, but also lead to injury of the skin that does not allow you to wear a wig-pickguard for a long time without having to remove.

Closest to the proposed technical restaurantsa invention "And partial wig", patent GB No. 1169795 published 1969-11-05, IPC A41G 3/00; containing the frontal part of the basis of flexible sheet material of the desired contour, which has the front and rear outer faces approaching each other at the ends of the major axis of the ellipse to form use of the band limiting circuit, a narrow back lane and hair, protected and distributed in the region of the external surface of the frontal part and bands of the bounding contour. However, this invention does not solve the task of implementing a more accurate three-dimensional form of the part of the head, where the problem area to better simulate the skin with a natural growth of hair, because in the process of wearing the substrate in accordance with the proposed design framework is deformed. In addition, the invention does not solve the task of giving to the Foundation after fixing her hair and covering the basics sticky substance required fracture toughness, i.e. the damage layer gluing hair bending that can occur when wearing a hair prosthesis, and when it is mounted on the head.

In the manufacture of hair prostheses required to solve the problem of simulation of the scalp. As to simulate natural hair growth requires combing hair prosthesis skin was streaked through her hair and looked the Roubaud, unnaturally, requires the absence of any ribs that would be visible and did not correspond to the qualities of the skin in appearance, namely: required in appearance smooth, natural color and elastic surface that mimics the scalp. In addition, it is necessary that the base is too close to the problem area of the head, without forming any folds and wrinkles, which will also give unnatural hair prosthesis. Therefore, when the qualities of the material thin, flexible framework is required that the basis of well-preserved shape problem areas, despite the complex three-dimensional surface of this zone, as well as most accurately repeated its shape. In addition, you want the base after fixing her hair and covering the basics sticky substance provided the required strength of the fracture, i.e. the damage layer gluing hair when bending. Only in this case, the basis for hair prosthesis allows multiple use of the hair prosthesis without loss of quality.

The technical result of the claimed technical solution is the implementation of a more accurate three-dimensional form of the denture bases close to the shape of the plot of the head, where the problem area to better simulate the skin with a natural growth of hair and making basis after fixing Nana hair and cover the basics sticky substance required fracture toughness, i.e. damage layer gluing hair bending that will allow a lot of time to use the hair prosthesis without losing its form and quality.

This technical result is achieved due to the fact that the hair prosthesis can be fixed on the basis of hair, protected and distributed in the area of the external surface of the frontal part, the strips forming the contour of the hair prosthesis, including the frontal part (A) of the flexible material to the desired contour and strip (1)having front and rear faces (a, b), approaching to each other in the occipital part (B) for forming strips of the bounding contour (2) and strips forming the circuit. Hair prosthesis characterized in that the base of the prosthesis is made of a thin material having a smooth, slippery surface, with successively applied layers of impregnation of the adhesive substance comprises superimposed on a circle at each other in overlapping strips (1) with allowance made of taped material, and forming a space-spherical shape of the base, with the frontal and occipital parts (B) basis and includes a band limiting circuit (1)forming the contour of the strip (3) and strip the occipital part (4), the front face (a) which have the tension on the front surfaces of the frontal part (A), for example, along the common thread of the material, and all overlay each other on the OS of the bounding contour (2), forming the contour of the strips (3) and strips the occipital part (4)fixed on the allowances among themselves, for example, firmware (5), the part of the bands in the left temporal region (C) and in the right temporal region (′) each forming a loop strips (2) and band limiting circuit (3) is fixed, for example, by gluing in the occipital part (B) of the framework.

The technical solution is illustrated by the drawings.

Basis (Montour) consists of strips (1) - bands ogranichivayas the circuit (2), forming the contour of the strips (3), bands occipital part (4). Each strip has a front ("a") and back (b) faces. The front face ("a") lanes converted to the frontal lobe (A) basis (Montour), and the rear "b" faces of the strips facing the occipital (B) the main parts (Montour). Each band has a seam allowance (6), which is superimposed on the allowance of the previous strip foundations (Montour). Each lane as a formative strip (3)and band limiting circuit (2) and strip the occipital part (4) in the fronto-temporal part (a-b) basis (Montour)corresponding to the frontal and temporal part of the head, have the tension along the grain lines ("in") of the respective strips basis. Left () and right ("`") part fixed overlay in the occipital part (B) basis (Montour). Strip sewn, for example, fishing line (5). The strips can be fixed and also glue. For mounting the strips in the basis (Montour) use a volumetric measure (7). Each strip foundations impregnated adhesive composition (8). After pinning the hair into the hair prosthesis based on the back side glue again to obtain a smooth, natural, mimicking the skin's surface.

Known invention "Method of manufacturing a wig designed for sticking on the part of the body of toy figures, and part of the body of the toy figures glued to her wig" patent RU No. 2145510 published 2000.02.20, IPC AN 3/44, to the torus at the base of hairs sewn flat on a flexible basis, for example on a textile backing. However, the invention does not allow for precise three-dimensional shape of part of the head, where the problem area to better simulate the skin with a natural growth of hair.

Closest to the proposed technical solution is the invention of "A disposable wig", international patent WO2005032291, publication 2005-04-14, IPC A41G 3/00, which form the basis of an extremely thin sheet directly on the problem area of the head, hair material, embedded in the base and fasten adhesive layer mounted on the rear surface of the substrate. The wig consists of separate parts, but these parts are completely unrelated, and just close isolated problem areas on the head, i.e. it is very difficult to fix. In addition, hair prosthesis is made removable and is made directly to the head of the person that requires a lot of time fixing it on the head. Hair prosthesis can be worn for a short time, because a very thin basis torn and she after fixing her hair and covering the basics sticky substance does not provide the necessary strength at break, i.e. the damage layer gluing hair at the bend.

Due to the fact that the problematic area, where you want to put the hair prosthesis, has a complex, three-dimensional shape with a cut to what AMI, the formation of the edges of the canvas so that it is not deformed in the process of wearing, but at the same time just had a shape problem areas, it is not possible without violating the elasticity of the edge and its integrity. So traditionally made the pattern by which the edge in the case of the presence of large projections and depressions just cut through the already formed the substrate surface. This violated the elasticity of the edge and were not allowed to make a well-adjacent convex parts of the head without additional tucks. The presence of tucks much all this coarsens the consciousness basis and, in addition, tuck visible under the hair prosthesis and do not allow to precisely simulate the scalp, forming folds and seams. In addition, the coarse Foundation damage the skin of the head when worn and broken at the bend of the framework.

The technical result of the proposed invention is to make the basis of after fixing her hair and covering the basics sticky substance required fracture toughness, i.e. the damage layer gluing hair bending, and performing elastic region basis, repeating complex contour problem areas without disrupting the structure of the edges of the fabric base. This provides, in turn, the implementation of a more accurate three-dimensional form of the part of the head, where the problem area to better simulate the skin with estestvennosti hair. Due to the elasticity and strength on the basis of the fracture is achieved the ability to reliably and naturally affix the prosthesis to the problematic areas of the head, which will fit snugly to the head, and the ability reusable hair prosthesis without loss of form and quality.

This technical result is achieved due to the fact that making the basis for hair prosthesis is to form the basis of a thin material, fixing the hair on the outer side of the base and cover the basics on the back of the foundations of the adhesive layer. The method differs in that the prepared fabric base, proKLIMA part of the fabric of the limited area, for example ranging from 0.5 to 1 m2taut with subsequent drying adhesive layer of cold air. On prepared volumetric measure problem areas of the head place a segment taped material on the Central axis of the volumetric measurements (7), combining the middle of the equity cut edge of the fabric with fixing it on the edge of the measurements after uniform tension common thread (in) cut edge of the fabric in both directions along the fronto-temporal part (a-b) measurements. Cut out the locking and/or bounding contour band (2, 3) wide, depending on the size and configuration of the volumetric measurements, for example, 2-3 cm in the front and rear Grana the bands allowance from 0.5 to 1.5, see Moreover, the internal circuit ("b"), as the locking contour strip (3)and the bounding contour of the strip (2), the cut begins with the occipital region (B) to the area of the frontal-parietal (a-b) zones, connect and fix, for example, create more gluing (8) the left and right part (In-`) fabric strips (1) in the occipital region (B) basis, repeat the operation on the number of necessary fixing base strips. The last part of the hemisphere oval shape is fixed by the length of taped material - occipital stripe with the formation of the seam allowance on the front face, forming a strip of the back part (4). Then all blend fabric strips stitch (5), for example, fishing line, based glue, pressure-sensitive adhesive on the rear side (8) and dried in cold air.

The proposed method is illustrated with drawings.

Fig - tension flat piece of fabric basics, glued on the device.

Fig.9 - overlay fabric basis on volumetric measurements.

Figure 10 - cut the excess fabric pieces after attaching strip on the basis of the tension along the grain lines and leaving the seam allowance on the back of the strip.

The basis is made as follows. On a volumetric measure (7) impose a pre-tensioned by the common thread ("in") fabric, for example a thin nylon fabric. The tension provided by the frontal part (A) basis to temporal parts (and the` ) basis. Right (`) and the left part (C) as of the bands, the bounding contour (2), and forming the strips (3), connected by overlapping their ends in the back of the base. Forming strips may be one or several, depending on the size of the product. Strips stacked on top of each other taking into account allowances (6). Impregnation of each strip is carried out after its fastening on volumetric measure (7). Guide strips symmetrically relative to the Central part of the volumetric measurements (7) along the axis running from the frontal part (A) basis to its posterior part (B). The last clip strip occipital part (4) bases. Stitch (5) each strip, for example, fishing line and cover the inner part of the base (Montour) adhesive (8). The band limiting circuit (2) (in accordance with volumetric measurement), have respectively twits circuit due to the tension of the strip by the common thread of the fabric strip. The difference in thickness basis between the parts of the strips, formed through the base material strip and overlay one lane to another is offset by the fact that the more delicate parts of the framework are filled with the adhesive composition (8), which provides elasticity to the basics. Band width "H" depends on the size of the head and the presence of bumps and hollows on a volumetric measure, repeating all the irregularities of the head in the problem area. When large size is x band width may be about 4-7 cm, at small sizes 2-4, see if there are depressions and bumps that need to simulate on the basis of the width of the bands can be reduced to 1.0-1.5 cm bandwidth Selection should satisfy the requirement of the absence of folds and tucks on the strip in position and fastening in a taut three-dimensional measure (7). Allowances (6), which are left on the strips can be from 0.5 cm to 1.5 cm Strips fixed on allowances or firmware (5), for example, fishing line, or just gluing on allowances (8).

Strength circuit fundamentals provide due to tension the common thread in the fabric when it's fixed in basis. In addition, it provides the best simulation of the scalp in the absence of tucks, ribs or firmware ribbons. When this construction is the basis for the wearing of hair remains constant volumetric shape of the base which fits snugly to the head. The elasticity and strength of the basics makes it convenient to fix on the head and repeatedly remove and attach the hair prosthesis. In addition, on the basis it is convenient to sew the hair in accordance with the areas of hair growth, in which it is convenient to simulate the natural direction of hair growth due to the fact that the basis of elastic after sewing the hair they are not deployed and held in a given when shivanie direction.

Thus the m technical result is achieved more accurate three-dimensional form of the base, as close as possible to the shape of part of the head, where the problem area to better simulate the skin with a natural growth of hair and making basis after fixing her hair and covering the basics sticky substance required fracture toughness, i.e. the damage layer gluing hair bending that will allow a lot of time to use the hair prosthesis without loss of quality.

The method is as follows.

Pre-prepare a volumetric measure (7). For example, by imposing a flat piece of fabric on the problem of the head and glued his stripes, for example, adhesive tape. As hard volumetric measurements (7) can be used, for example, also a plaster cast. On the measure indicate areas of hair growth (a, b,`B), the top of the head. As the fabric for the base take, for example, a thin transparent nylon. Hard volumetric measurement follows the contour problem areas of the head and has a smooth, flat surface.

Pre-prepare the fabric base (Montour), for example, as follows. Cut the fabric, for example, an area of 0.5-1 m2, pull the fabric, for example, on the frame, glue it adhesive, such as rubber glue, dry cold air, for example, by using a Hairdryer. Then the middle of the equity edge (see Figure 5) fabric is fixed on the middle of the frontal part of Erki using pins, starting from the middle, pull the fabric along the grain edge tight to the fronto-temporal (a-b) side scoops at both sides, tightly fix the pins to measure 2-3 refer to Impose fabric contour measurements, tracking airtight material to the pattern measurements, the locking pins. Outline on the fabric pattern of external and internal perimeter measurements (width of 3-4 cm). Cut the fabric along the outer perimeter of the front face of the strip "a"), leaving a 1.5 cm seam allowance. Cut the fabric along the inner perimeter of the "b" on the rear face of the strip), starting from the occipital region (B) and ending in the region of the frontal-parietal (a-b) zones, leaving from the edges of the inner perimeter of 1.5 cm seam allowance. Connect and fix the left and right part of (and In`) bands in the occipital region (B), glue, pressure-sensitive adhesive (8). In the area not covered with cloth of the same steps as in the formation of the previous strip. The last of the occipital area of the base of the hemisphere is always oval in shape, it is covered by a strip of the back part (4), following the same requirements for tension fabric and abandonment of allowances, as the previous bands. Fix a basis (Montour). Then all blend fabric strips on allowances (6) stitch (5) scaffold. Fabric base (Montour) glue adhesive, such as rubber glue. Dry basis (Montour) cold dryer. Sewn hair is s. Shoot it with the bulk measurements (7). Glue the fabric basics inside the adhesive composition. Dry cold dryers.

Thus achieve the effect of giving to the Foundation after fixing her hair and covering the basics sticky substance required fracture toughness, i.e. no damage layer gluing hair bending, and perform elastic region basis, repeating complex contour problem areas without disrupting the structure of the edges of the fabric base.
