Description

I

The invention relates to the manufacture of shoes, can be used when sewing model shoes, especially when making knotted parts of the bottom of shoes made of wood.

A known method of manufacturing a sole with a wooden heel by milling from a single piece, a main insole and a monolithic sole with a heel and then sticking them together with each other.

A known method of manufacturing a sole with a heel of valuable wood, such as beech, oak, mahogany, is done by milling from a single piece a piece that has the shape of a finished product. The resulting part is cut along a line parallel to its upper surface to form a main insole, in which holes are then made with grooves for fastening the details of the upper of the shoe. The main insole with the top of the shoe attached to it is attached to the sole 2.

The main disadvantages of all known methods are the high consumption of valuable wood due to the necessity of milling a given shape from a monolithic billet and low mechanical strength.

finished shoes, as this does not provide the optimal location of wood fibers relative to the effect of load on shoes and some of them work on chipping.

The closest technical solution

 is a method of making a sole with a heel from valuable wood, mainly oak, mahogany, which consists in cutting out the blanks of the sole and heel from a wooden deluxe, steaming it, forming the blank of the sole and heel in the matrix, substance, processing the lateral surface of the sole blanks and heel along the contour and fastening the obtained blanks of the sole and the heel between them 3.

The disadvantage of the proposed method is that the modes of steaming and drying the wooden blanks only create a uniform mechanical properties over the thicker, but do not provide the possibility of recovery. Possibilities of forming high-heeled shoes.

The aim of the invention is to increase the mechanical strength of the sole.

To do this, the previous method of making a sole with a heel of fine wood, mainly oak, mahogany, consists in cutting out the blanks of the sole and heel from a wooden deluzhka, steaming it, molding the sole and heel in the matrix, drying, processing the side surface of the sole blanks and heel along the contour and fastening the obtained blanks of the sole and the heel together. In addition, when cutting, the sole blank is oriented along its axis of symmetry along the wood deluxe fibers, and the steaming of the sole and the heel blanks is performed at 100-139 ° C for 90-120 minutes, while drying the sole and heel drains, in the matrix at 100-120 ° C for 150-180 minutes.

The main feature of the method is that in its implementation the wood fibers are located along the sole track and along the axis of the heel, which ensures their reliable bending and compression while worn shoes.

The process technology is as follows. From wood of valuable species, sawn on boards with a thickness of 8–10 mm, blanks are cut out in the form of rectangular delyuzhek with a longitudinal arrangement of m fibers, which are then placed in a humidifying chamber, where they are steamed at a temperature of 100-130 ° C for 90 -120 minutes, after which the efforts of the press are pressed into matrices having the longitudinal profile of the finished bracelets and dried together with them in a drying unit at 100-120 ° C for 150-180 minutes. The molded profile delujs are removed from the dies, after which they are attached to them with the help of profile glue and glue for the heel so that the wood fibers of the heels are located along their axes. The resulting pre-fabricated blanks are milled along side contours to the finished form along a special contour.

Example 1. From beech boards 10 mm thick, along the fibers, rectangular ravines of 250 × 80 mm were cut, which were then placed in a humidification chamber, where they were steamed at 100 ° C for 90 minutes. Using a 60-ton press, moistened delugs were pressed into matrices having the profile profile of a woman's shoe, and then dried together with them in a drying chamber for 180 minutes. After drying, the profile diluques were removed from the matrix, and then, glue was attached to the blocks with glue nails to them. The resulting preform was processed by milling on the side surface to the finished type. The outer surface of the finished parts was covered with furniture lacquer and used for the manufacture of French model shoes.

Example 2. From oak boards 9 mm thick, along the fibers, there were cut rectangular deluzhes of size 250x80 mm, which

then placed in a humidification chamber, where they were steamed for 105 minutes. The moistened talings with the help of a 60-ton press were pressed in and the matrices with the profile of a trace of women's model shoes, and then dried together with sm. After drying, the profile diluques were removed from the matrix, and then the heel blanks were attached to them with glue nails on the glue. The resulting preform was processed by milling on the side surface to the finished type. The outer surface of the finished wood parts was covered with furniture lacquer and used to make women's model shoes.

An example about. Rectangular deluzhes of 250--80 mm in size were cut out of 8 mm thick mahogany boards, which were then placed in a humidification chamber, where they were steamed at 130 °

5 for 120 minutes Humidifying delyuzhki with pomop., 60-ton press were pressed into the matrix with the profile of the trace of women's shoes, and then dried together with them in a drying Ka.v.epe at 120 ° C for 150 minutes After drying the profile, the first knives were removed from the matrix, and then heel blanks were attached to them with profile nails on the glue. The bulk-collecting preform was processed by milling on the side surface to the finished form. The outer surface of the finished wooden parts cover; 1I furniture. varnish and used for the manufacture of women's. model shoes.

As a result of all three measurement measures, the soles with a heel were obtained, with a regular appearance, durable and precise. The implementation of the proposed method will make it possible to organize the production of durable and casual women's model shoes on wooden soles, while reducing the consumption of chain

wood by 30%. five
