Abstract

Usage: in light industry in the manufacture of summer shoes. SUMMARY OF THE INVENTION: Shoe preparation consists of a strap top and an insole. Through slits are made in the insole to accommodate the ends of the straps connected to the insole with a zig-zag seam. The insole is formed from two longitudinal parts connected to each other by a zig-zag-type butt joint, the insole being made from waste leatherette or fabrics. 7 il.

Description

The invention relates to the shoe industry and can be used in the manufacture of summer strap shoes.

A known design of blanks for open types of summer shoes made by adhesive fastening. In such a preform, the insole is made of two-layer, i.e. consists of a solid upper part and a lower one with nests provided along the edge of the perimeter. The inside edge of the upper parts is glued to the landing slots of the lower part of the insole.

The design of a summer open shoe is known, containing a strap top connected to an insole. At the same time, landing nests are made in the insole to accommodate the ends of the straps connected to the insole with a zig-zag butt joint.

The disadvantage of this solution is to make the insole from the upper material.

The purpose of the invention is to reduce the cost of shoes and save leather materials.

The goal is achieved due to the fact that the insole for the workpiece top of the shoe is made of two longitudinal parts, the volume of the top is formed by the installation and securing by machine seam of the details of the top of the shoe blank in the through seats of the insole,

An increase in the utilization rate of the material is achieved by dividing the insole into two longitudinal parts, which significantly reduces the intermodel and edge waste when cutting the source material.

FIG. 1 shows the first longitudinal portion of the insole; in fig. 2 - second longitudinal portion of the insole; in fig. 3 - details of the workpiece top shoes; in fig. 4 - the mutual arrangement and fastening of parts of the top of the workpiece in the landing slots of the first longitudinal

parts of the insole; in fig. 5 - the same, in the landing slots of the second longitudinal part of the insole; in fig. 6 - the assembly of the workpiece top shoes (stocking); in fig. 7 - a general view of the workpiece (stocking) in the collection.

The shoe blank contains the first longitudinal part of the insole 1 with through holes in the seating sockets 2 (Fig. 1) and the second longitudinal part of the insole 3 with through holes in the seating sockets 4 (Fig. 2), which are designed to install and fasten parts the top of the shoe covers 5, 6 and 8 (Fig. 3, 4, 5). In the details of the top 5, there are holes 7 for fastening the buckles 10. The top details of the shoes 5, 6, 8 are attached to the through holes of the seating slots 2 and 4 of the longitudinal parts of the insoles 1 and 3 with longitudinal seams 11 of zig-zag type (Fig. 4, 5, 6). The longitudinal parts of the insoles 1 and 3 are butt-joined in the middle in-line track line 12 by a longitudinal seam 13 of zig-zag type (Fig. 6, 7). A sole is attached to the insole of the shoe stock, consisting of two longitudinal parts 1 and 3, fastened end to end with a longitudinal seam 13 of zig-zag type. After removing the pads from the pads inside the shoe, a special insole is glued in, duplicated with the material of the top or lining of the workpiece and edged with a braid.

Shoe making is made in the following way.

The upper material, for example, artificial suede, is duplicated with the lining material, for example, vinyl leather-NT and, from the obtained duplicate material, cut down on presses, for example, PV-8, parts of the billets 5, 6, 8 (Fig. 3), and longitudinal parts Insoles 1 and 3 (figs. 1, 2) are made of vinyl leather or textile material. In parts x 5, holes 7 are punched to fasten the fasteners 10 (fig. 3, 4, 5,

6), and in parts 8 there are holes 9 (Fig. 3) for fastening the straps 10 (Figs. 5, 6, 7). In the through holes of the seating sockets 2 of the first longitudinal part of the insoles 1 (Fig. 1), the details of the top of the blanks 5 and 6 (Fig. 3) are inserted and stitched with a zigzag-type longitudinal seam 11 (Fig. 4, 5, 6, 7). In the through holes of the seating nests 4 of the second longitudinal part of the insoles 3 (Fig. 2) put the details of the top of the blanks 6 and 8 and also stitch the zig-zag type 11 with a longitudinal seam. The longitudinal parts of the insoles 1 and 3 (Fig. 5, 6, 7) are sewn with a zig-zag type 13 longitudinal seam (Fig. 6, 7). Thus, a billet is prepared for the top of a stocking-type shoe (Fig. 7), which is put on the shoe and glued to a monolithic molded sole, for example, polyurethane. After removing the shoes from the pads, a special insole, duplicated with the material of the top or lining and edged with a band of material from the top, is glued into the shoes.

The use of the invention will reduce the cost of footwear by reducing the labor intensity of manufacturing footwear by simplifying the production technology and increase the utilization rate of the starting material, since the insole is made of two longitudinal parts.

Claims (1)

Claims of the Invention Procurement of shoes, containing the top, made of straps, and an insole with through-fit seats, in which the straps are butt-fastened with a zigzag-like seam, characterized in that, in order to reduce the cost price of the gadget and save leather materials, the insole is made in the form of two longitudinal details interconnected by butt welds of zig-zag type, while the insole is made of waste leatherette or fabrics.
