Method for cutting of fur skins

FIELD: light industry, in particular, furrier and sewing industry for manufacture of fur products.

SUBSTANCE: method involves applying lines of predetermined configuration onto skin web; cutting skin web into fragments; shifting and connecting fragments, said lines being of two configurations: at least two parallel straight spaced lines serving as guides, extending in parallel with spine and having width of at least 0.5 cm, with space between parallel lines being equal to skin width minus width of guide multiplied by number of said lines, and drawing arcs between said lines, with radius of arc being equal to width of skin, said arcs extending from center selected on axis and disposed in the middle between guides; after shifting, folding each arced fragment so that skin web is facing inward; performing joining in two steps: initially joining folded fragments with guides and then with each other.

The invention relates to light industry and can be used in furrier-sewing production in the manufacture of fur.

The known method of cutting fur skins in the process of manufacture of hats, including drawing on the leather skin of lines of a given configuration corresponding to the outline of the pattern, perforated leather in some areas, cutting and connection details (RF patent No. 2019111 And 42 With 1/00, 1994, BI No. 17).

There is also known a method of cutting fur skins, which is closest to the proposed method of technical substance. It is applied to the leather lines of a given configuration, the cutting of these lines, offset and staple the leather (gevorkiantz S.A. and other Development and adaptation of methods of decorative finishing details of the fur products / j-l "Fur Peace", 2000, No. 3, pp.62-65 - prototype).

However, the technological capabilities of these methods are limited in terms of manufacturing double-sided fur.

The objective of the proposed method of cutting fur skins is expanding the technological capabilities of the method of cutting in the manufacture of products-transformers without changing the geometric shape of the skin when the skin is viewed not as a static component and a dynamic element design.

Put ass the cha is achieved by the proposed method of cutting fur skins. The essence of the method consists in the following: in the way of cutting fur skins by applying to the leather lines of a given configuration, cutting the lines into fragments, offsets and connections fragments line put two configurations: direct - guides parallel to the ridge line of not less than 2, with a width of not less than 0.5 cm, at a distance from each other equal to the width of the skin minus the width of the guide, multiplied by their number, and between the arc radius equal to the width of the skins from the center, selected on an axis located midway between the rails, after shifting each curve fragment put Koshevoy fabric inside, and the connection is carried out in two stages - first, connect the folded sections of the guide, and then with each other. The connection is composed of fragments of skins carry a cord or braid with hinged hooks and loops, or through the braid lightning bolt.

Comparative analysis of the claimed technical solution with the prototype shows that the proposed method differs from the known fact that the applied line two configurations: direct - guides parallel to the ridge line of not less than 2, with a width of not less than 0.5 cm at a distance from each other equal to the width of the skin minus the width of the guide, multiplied by the number of them, and between them - the arc R is DICOM, equal to the width of the skins from the center, selected on an axis located midway between the rails, after shifting each curve fragment stack Koshevoy fabric inside, the connection is carried out in two stages - initially composed of fragments connected with the guides, and then with each other.

The mentioned set of features in comparison with the prototype provides the achievement of the claimed technical result. The declared parameters of the method are optimal.

Build options direct - guides and arcs determined depending on the specifics of the skin, its length and strength of the leather. Guides to the width may be equal to or different from each other. The most optimal is the number of direct - guides, equal to 3, is symmetrical cutting. The arc between the rails build arbitrarily selected step.

The invention explains the scheme (see drawing): a - drawing on the leather skin of the lines of two configurations; b - cut skins, displacement and folding of the fragments Koshevoy fabric inside; in connection fragments. 1 - direct - guides; 2 - arc; LSHK- length skins; MSHK- width skins; mH1,2,3- the width of the straight rails; mn1,2,3- the distance between the rails; R - the radius of the arc is equal to MSHK; h - step arc; OO - line range of scorch is; O1O1and O2About2the axis of the middle between the rails.

The method of cutting of fur skins (for example, mink) is as follows (see drawing). Source data: LSHK=46 cm, MSHK=10 cm

First select the number of direct - guides, it is equal to 3 when the width of 1 cm (mH1=mH2=mH3=1 cm), determine the distance between them: mn1=mn2=3,5 see the Width of each section between the guide is divided in half and spend the axis O1O1and O2O2. These axes are arbitrarily selected step (h=2.0 cm) note equal parts. Then build the arc between the rails, for which a radius of 10 cm (R=MSHK), from the center, located on the axis O1O1and O2O2spend the arc, the distance between them corresponds to the selected step is h=2 Then see the skin on the leather cut along marked lines and shift relative to each other, and then each arcuate fragment stack Koshevoy fabric inside and connect with the guides (seam), then connect them with each other (cord).

The proposed method for cutting fur skins was tested with a positive result.

This method extends the technological capabilities of cutting fur skins in the manufacture of double-sided products, transformers, and it allows the t to produce these products without changing the geometric shape of the skins while reducing material consumption, the weight and improve the drapeness.
