SU66950A1 - Hot Cured Shoes - Google Patents

Description

The present invention relates to the design of a shoe made by sandal pulling and attaching the sole by hot curing.

In the usual practice of attaching rubber soles by the method of hot vulcanization, the preparation of shoes for attaching the bottom consists in meckey tightening with texas and in subsequent pacing and. horoshemy tightening "romki. In this case, the curved ends of the texas protrude to the surface of the insole inside the finished shoe, which is considered undesirable; due to the inevitable folds, it is difficult to achieve a uniform roughness of the pulling edge, especially in the toes.

The present invention aims to provide a shoe design made by combining sandal puffing with a method of hot vulcanizing the sole, characterized in that in order to securely attach the sole to the shoe upper along the edges of the insole and shoe upper beyond the edge of the shoe, the vulcanization is filled with rubber, forming rivets.

FIG. 1 shows a part of the workpiece after cutting special holes; FIG. 2 shows a cross-section of the shoe along the toe part, FIG. 3 is a horizontal section, FIG. 4-side view of the shoe by GG in FIG. 2

A blank / shoe or other shoe, preferably without a pad. crosslinked in the usual manner. Then follows the overlay of the insole 2 and putting the workpiece on the shoe. Insole 2, unlike conventional ones, has an allowance for sandal puffs around the perimeter and can be made of textiles or cardboard with a thickness of 2 mm or less. Sanding the workpiece / on the insole 2 is made with glue, brackets or threads by using already known machines or manually. Further, along the tightening edge along its perimeter, through the top / and the insole 2, holes 7 are cut through, which serve to form rubber stitches or rivets (see Fig. 1), and it is necessary that the holes 7 be more than half the diameter top / and insoles 2 (see Fig. 3). 7 holes can have different

a shape (other than that shown in the drawing, for example, a triangular section). The next step is to attach the calf to the insole, and it is desirable that the calf has the shape of a semi-insole, but somewhat smaller in size, since such a calf provides reliable support for the leg and lowers the consumption of the rubber compound. The final step is to attach the sole by means of hot vulcanization, which is accompanied by the formation of the welt 3, rubber stitches or rivets 7, the stitching S, the heel 6 and the sole 9 which make up together.
