Method to obtain one-piece moulded detail of felt Invention relates to a light industry and can be used in manufacture of clothes, shoes, hats and decorative items made of felt as well as at for felt products restoration. The method includes forming a canvas by stacking layers of wool fibers and applying on the layers of wool fiber of textile material, felting, felling and drying. On the canvas from the side of textile material the layers of wool fibers are additionally placed. After felling the moulding is carried out, and after drying - wet-heating treatment. Wet-heating treatment is carried out under pressure at a temperature of 120-150° C, corresponding to a temperature of adhesion of adhesive. As textile material the easily mouldable adhesive gasket material with sparse structure is used. The adhesive gasket material can be placed in accordance with the zones marked on the detail. |

Removable shoe soles "demashi" Invention relates to removable soles containing fixing devices to attach to the shoe, characterised in the fact that for the purpose of applying the information to the surface where the pedestrian is moving, soles are composed of at least three layers, the first layer is made in the form of rigid ribs, made of solid material inside which for storage liquid dying material there are cavities connected by slits with the second layer of flexible material having an internal porosity, which provides the movement of liquid dying material, and the third layer, consisting of the outer sections with closed pores and areas with open pores. |

Invention relates to shoes production. Footwear has upper and sole with elevated part, say, toe part and heel part buffers. Proposed method uses mould with last whereon upper is laid. Note here that mould top part is divided into two lateral parts, top part displacing sideways from last bottom part between first and second positions relative to bottom part, and mould bottom part displacing vertically relative to mould top part between third and fourth position. In compliance with this method, sole 3 is placed into mould bottom part 4 while upper 2 is placed into mould cavity, at least, one lateral side 5 is displaced relative to other lateral side 5 from first position into second position. This results in that both lateral sides thrust against upper 2 for jointing sole to upper and producing interlayer 9. Note here that mould bottom part 4 is displaced toward upper 3 from third position into fourth position so that toe part 8 of sole elevated part 7 is pressed against upper 2 by guide surface 13 formed by mould lateral parts 5 so that clearance is retained between upper 2 and sole elevated part 7. Note here that the latter and mould lateral part 5 make top limit of injected composition spread. |

Process of desodorisation and microcirculation of shoes Invention relates to ventilated shoes. Processing of internal surface of shoes includes injection with pump of feeding section into the inner cavity of the shoe of atmospheric air. The air is cleaned of dust through the filter-cartridge creating by dispensing three-position regulator of flow of mixture of air with biologically active substances. |

Electrically conductive athletic shoes Invention relates to a method of treatment, prevention of state or human disease with the use of electrically conducting athletic footwear which provides natural stimulation of foot reflex zones while doing exercises at grounded exercise machines and on the floor with grounded floor covering in home conditions and in special sports facilities. Object of the invention is to obtain the material of sole of athletic shoes of electrically conductive properties due to adding gold powder to the material during the manufacture of shoe sole, which provides good electrical conductivity of the material and curative effect on the body. Electrically conductive sports shoes for stimulation reflex zones of foot has the upper and the sole made of electrically conductive material, socks made of electrically conductive fabric with the same filler. At that gold powder is added to the material of sports shoes sole during their manufacture, in an amount of 1.00 g to 2.00 g and more per one pair of shoes (depending on the type of shoe). |

Method for determining relative humidity of leather and footwear blanks Invention relates to light industry, in particular, to processing in vacuum of leather and footwear blanks, performed in the manufacture of shoes. According to the method, functional dependence of amount of moisture condensed in microcapillaries of leather and footwear blanks on their original parameters and process indicators of hygrothermal processing is formed; criterial expression of similarity of footwear processes, which are real and prescribed by the technology, is obtained. With the help of special software the criterion of similarity of these processes is calculated, and then the indirect diagnostic parameters of the real process are measured, such as pressure and temperature of the working environment. By criterial expression the desired value of moisture condensed in microcapillaries is determined, and using a calibration curve it is transferred into percent of relative humidity of leather and footwear blanks. |

Method of manufacturing footwear Invention discloses a method of manufacturing footwear which uses the first form made of rigid material and the second form provided with a groove into which footwear is placed. Footwear includes an upper part, the connecting element and a sole, fastened to the upper part. The second form transfers heat energy generated by ultrasound to the connecting element and the sole, so that the connecting element and the sole are properly reduced in size and are securely fitted to the upper part. (dwg. 3). |

Element for prevention shoe sliding Anti-sliding shoe element protruding over the surface of the shoe sole is made of vertical plates perpendicularly crossed in their centers, the lower edges of which are sharpened for better traction on snow and ice surface. The end of the plates deepened in the shoe sole, has a T-shaped cross section and ends with a horizontal strip of width 4-8 mm and thickness of 2-3 mm. |

Footwear product (100) has a top (112) and a sole (114), and the design of the top (112) has a face material (116) and air permeable layer (140) located at the tread of the top. The air permeable layer (140) is located in the bottom of the structure (112) facing the sole, of the top of the sole (114), and this air permeable layer (140) has a horizontal three-dimensional structure that allows the passage of air. Facing the sole bottom peripheral region of the facial material (116) of the top, at least in part of its circumferential length is changed with at least one connecting material (210), which, at least, beginning over the bottom part of the air-permeable layer (140) and passing out of air-permeable layer (140) is located at the tread of the top and at least in one partial area, which is at least partially located on the same height as the air-permeable layer (140), is air-permeable and thus combines air-permeable layer (140) with the environment in a way that air exchange is possible between the environment and air-permeable layer (140). |

Method of pressure moulding of blanks of upper part of shoes Method of pressure moulding of blanks of upper parts of shoes, comprising the following steps: putting a blank on a hollow perforated block; sealing the interior hollow of the block by placing on the surface of a blank of an airtight film, creating a vacuum under the block; moistening of the blank from inside; moulding (extraction); stabilisation of the shape of the blank by means of its cyclic drying from inside and creation of pressure on the surface of the blank with an airtight film of atmospheric pressure higher by 2.5-3 times. Pressure is applied to the blank cyclically in parallel with cyclic drying from inside, i.e. repeatedly loading and unloading the part, and evacuation is carried out while exposure of the blank before each cycle. |

Method to manufacture simple orthopaedic shoes Proposed method to manufacture simple orthopaedic shoes designed to correct defects of a plantar foot part applies a composite insole made of two parts that are temporarily connected to each other with a double-sided adhesive tape to perform a technological process. After manufacturing and removal of shoes from a last, the upper part of the composite insole is removed, and an orthopaedic insole is fixed in its place. For tack tightening of an upper blank, a metal part in the form of a horseshoe is installed into the upper part of the composite insole to follow the contour of the tightening edge, which provides for bending of the tack sharp edge. |
