RU2082620C1 - Method of hand laying of embossed patterns on leather - Google Patents

Abstract

FIELD: decoration of leather products. SUBSTANCE: to obtain embossed patterns, the known technique of leather drapery is combined with methods of production of patterns by wrinkles by analogy with "origami" Japanese art, taking into account leather natural and physical properties and using for beginning straightened and dry leather subjected to thermal treatment without searing of preparation. Wrinkles are made by pressing-down of leather on face side with a subsequent sizing of preparation by sections in process of formation of wrinkles. EFFECT: enhanced quality.

Description

 The invention relates to methods for decorative decoration of various goods of art crafts and can be used for processing relief patterns on leather blanks.

 To obtain embossed patterns on the skin, various methods are known using stamps, presses, etc.

 So, for example, a method of embossing leather parts on a mobile press is known, which consists in placing an engraving or zincographic plate with the pattern up on the lower movable part of the press, then the part is placed on it face down to the drawing. A rubber or cardboard pad is attached to the top of the press. The sliding part of the press is retracted, the table is lifted and embossed.

 The disadvantage of this method is the unsatisfactory study of the figure.

 An invention has also been registered on a method of embossing patterns on sheet blanks, namely, that the blank is placed between the pattern-forming elements and the elastic plate, on the opposite side of which they are affected by an electrohydroimpulse discharge. This method is also not able to create an exquisite pattern.

 The easiest way to get a relief is to stick the cord between two layers of leather, but this method is only applicable for thin soft leathers and is suitable for emphasizing the reliefs of straight or smoothly rounded lines, for example for belts and decorating the edge of the subject as a finish.

 Since ancient times, the peoples of the Far North used ornamental patterns in their products, but they performed them using the applique method. Some northern ornaments are lined with narrow straps of soft thin leather. This method is applicable in products made in folklore style.

 The so-called "drapery" or "blind man" is generally accepted. A piece of skin is slightly moistened with water and knead in the hands. They put the skin on the board with the baktarmany side up and lubricate it with rubber glue after the glue dries, repeat this procedure again. Then the skin is turned upside down and on a flat, even surface with your hands begin to give the skin the necessary folds. For finer elaboration of folds, this work is continued with tweezers.

 To get really complex patterns with this method, you need to have very great skills and have great experience working with the skin.

 The basis of the present invention is the creation of such a technique for working with leather, which would allow to create a variety of decorative products, expanding the artistic and structural capabilities of the decorative and applied parts of leather with little experience with leather.

 For work, an unkempt and dry flat skin blank is taken. If the skin at the preparatory stage is not soaked and not kneaded, but rather ironed through the paper on the baktarmany side with a hot iron without cauterizing the workpiece, then it will acquire paper properties for a while, i.e. the ability to create straight folds.

 In Japan, there is the national art of "origami", which means "folded paper", when by creating numerous folds a variety of voluminous products are obtained.

 Until the skin blank has got stiffness, which remains until it has been crushed, it is gently smeared with a thin layer of glue from the wrong side, it is allowed to dry with glue and begin to put the pattern with your hands and tweezers, creating wrinkles and creases on the front side, fixing the obtained stages of the plan and an embodied pattern with glue in the process of forming folds. Moreover, due to the fact that the skin is essentially a plastic material, it makes it possible by compression or stretching to create additional picture elements in those areas that would be impossible to use when working with paper. The choice of the sequential masonry of certain elements and the conditions for their arrangement provide a variety of artistic forms of decorative and applied products.

Claims (1)

 The method of manual laying of embossed patterns on the skin, which consists in preliminary preparation of the workpiece, gluing the workpiece from the barmony side and making wrinkles with leather skins on the front side of the workpiece with their subsequent fixation when the glue dries, characterized in that during preparation of the workpiece it is heat treated with smoothing without cauterization of the workpiece, and sizing is carried out on sections of the workpiece in the process of forming folds.
