Description

BACKGROUND OF THE INVENTION The present invention relates to a method of forming an imitation of layering of slices of natural underwear on a uniform heel-colored shoe heel covering material.

Higher demands are increasingly requiring production to hand-made models of natural leather footwear to customers. Manufacturers solve this problem by trying to imitate handwork and natural material. The marketability of the shoe with such imitations, and hence its price, then greatly depends on the visual, and possibly omalor credibility of the imitations made.

Shoe heels are currently produced mostly by very productive plastic molding. The heel moldings are then treated by dyeing or coating.

There are known methods for imitating the layering of natural leather slices in which colored strips are formed either directly on the heel molding or on the coating material, the width of which is equal to the thickness of the underlying natural leather. The cross-section of the underlying natural leather is not evenly colored throughout its thickness, and its imitation by the mere deposition of color is visually very flat and completely unreliable.

This disadvantage is overcome by the method of making an imitation according to the invention, which comprises pressing the relief of the imitating edges interconnected with bevels to form the bevelled ribs, and then wiping off the color of the bevel perpendicularly to the contour direction of the bevelled ribs.

The superior effect of the method according to the invention is that by wiping the color of the face perpendicular to the contours of the beveled ribs, the contours of a light shade are formed, which gradually change to the shade of the basic uniform color. This color treatment, together with the bevelled ribs, is very plastic and imitates the appearance of the laminated wafer sheets.

An exemplary embodiment of the method is shown schematically in the drawing, wherein FIG. 1 is a cross-sectional view of the coating material at. Fig. 2 is a cross-sectional view of the coating material when wiping the paint on a larger scale; and Fig. 3 is a perspective view of the finished heel of the shoe.

The coating material 1 / fig. 1) is cut out of natural or artificial leather, which is uniformly colored on the liner 11 in the darkest shade of the treated cross-section of the bottom leather.

The relief 2 of the imitation edges 21, whose distances a correspond to the thickness t, are pressed into the liner 11 of the coating material 1. 3 / imitated petals natural bottom. leather. The positioning edges 21 are connected to each other by bevels 22 at an angle of α. A rubber flexible tab 2 is placed on the reverse side 12 of the covering material 1 as the bevelled imitation edges 21 are pressed.

When the imitating edges 21 are pushed, deformations occur on the coating material 3, resulting in bevelled ribs 13. The greatest deformations occur at the imitating edges of the imitating edges 21, from where they gradually decrease to the impression of the adjacent imitating edge. The magnitude of these deformations is proportional to the magnitude of the bevel angle 22. After the sweat of the freckles has been released, the elastic portion of the deformations gradually disappears, but the plastic portion of the deformations remains permanent.

The thus treated coating material 1 is then deposited on a flat pad 4 / FIG. 2j and the paint 11 is wiped with a brush in a direction perpendicular to the contour direction of the tapered ribs 13. The brush 1 is rotated in the direction s1, the coating material 1 with the flat washer ee shifts in the direction s2. Thus, at the apexes of the bevelled ribs 13, a light shade contour is formed, which gradually, in an intensity inversely proportional to the magnitude of the bevel angle 22 of the imitation edges 21, transitions to shades of the basic uniform color of the liner 11.

The face side of the lining material 1 can be further treated to the desired shade, gloss, etc. after the imitation has been formed. The lining material 1 is then adhered to the surface of the heel molding G, which is finally provided with a bolt 7 and fastened to the bottom.

The method according to the invention can also be used to create imitation layering of sheets of natural underwear even directly on the heel moldings G of the heel. For this purpose, a tread is formed in the molding cavity of the mold which produces similar bevelled ribs on the circumferential surface of the heel molding that are formed when the relief 2 of the imitation edges 21 is pressed into the coating material 7. The treated heel moldings are then provided with a uniform coloration which is wiped in a direction perpendicular to the contours of the bevelled ribs.
