Line processing of leather and fur

 

(57) Abstract:

Line processing of leather and fur, characterized in that it has a device for holding a liquid processing semi-finished product, comprising successively installed vibro plates and placed between squeeze rollers mounted on the last pair of wringer rolls vibrotransporter with roller mechanism for feeding semifinished product on doubling the knife device for doubling the semi-finished product on leather and fur part of the semi-finished product, vibrotransporter to supply the fur part of the semi-finished product in a device for grinding the fur part of the semi-finished product containing two shafts, one of which is a grinding, and vibrotransporter guides feed the leather part of the semi-finished product in a device for grinding the leather part of the semi-finished product, made in the form of two grinding shaft with an adjustable gap between them, a device for applying liquid solutions on leather and fur part of the semi-finished product having namazie shafts, and a device for drying and split leather and fur semi-finished parts made in the form of vibrating plates.

FIELD: production of fur articles.

SUBSTANCE: method involves applying fur strips with its side opposite to pile surface to substrate surface and attaching said strips on surface by wrapping with thread stitch loops at outside for closing at least part of substrate surface with piles of strips; applying each fur strip onto substrate surface for defining alternating rectilinear and looped portions; providing attachment of said strips along the entire length of rectilinear portions, with fur strips being arranged along width of substrate at frequency directly proportional to density of fur article to be manufactured.

EFFECT: reduced labor consumption and wider range of fur articles.

FIELD: fur industry.

SUBSTANCE: method involves providing fur strips; forming pairs of adjacent strips so that their piles are arranged at different sides of plane of fur sheet; joining fur strips to one another at individual portions, each of said portions having length equal to at least 1/5 the length of non-joined portion.

EFFECT: reduced labor consumption, improved quality and wider range of articles manufactured with the use of fur.

FIELD: bird skin dressing processes.

SUBSTANCE: method involves strictly observing succession of performing operations for preliminary processing of skins including steps of bird skinning in single sheet by cutting it along line running from region above beak on upper side of head and spine line to tail base; impregnating feather cover with absorbing powder; degreasing and cleaning skin by scraping with obtuse-angled knife from tail to head while adding absorbing powder; washing skin in detergent solution and adding washing degreasing means; drying skins in desiccant powder medium; knocking out desiccant powder from skin by means of spade; fixing skin by means of pins and preserving with the use of acidic-saline solution. Starch is used as absorbing powder and desiccant powder. Wide range of aquatic bird skins are suitable with regard to strength of flesh side, density, strength and beauty of color of bird's feather cover for dressing into fur articles. Method allows settling of fat and other contaminants onto feather cover to be prevented and bird skin drying process to be performed under predetermined conditions with the use of starch as absorbing powder and desiccant for imparting initial appearance to dressed feather cover with regard to direction of feathers and natural color.

EFFECT: increased physical-mechanical properties of dressed bird skin as compared to skins of fur animals dressed by way of standard processes.

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 straight parallel 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 between guides; before cutting procedure, plotting two lines at both sides of spine line, said lines extending through points at ends of penultimate arcs in skin base, and through points disposed at a distance of up to 25% the width of skin on first arcs provided in upper part of skin; shifting and connecting said fragments along said line.

EFFECT: wider operational capabilities in cutting of fur skins and wider range of fur products manufactured by method.

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.

EFFECT: wider operational capabilities in cutting of fur skins for manufacture of double-sided articles.

FIELD: light industry; methods of treatment of the furry semi-finished products.

SUBSTANCE: the invention is pertaining to the field of light industry, in particular, to the method of treatment of the furry semi-finished products. The furry semi-finished product is treated with the low-temperature plasma in the vacuum chamber under pressure of 25-30 Pa in the medium of the argon gas. The treatment is conducted at the oscillator frequency of 13.56 MHz, with the current strength on the anode of the oscillation valve of 0.65-0.8 A within plasma action time of 3-5 minutes and at the rate of argon consumption of 0.03-0.05 g/s. The technical result of the invention is reduction of the fur abradability, the increased strength of bonding of the fur side with the skin tissue and strength of a hair at stretching.

EFFECT: the invention ensures reduction of the fur abradability, the increased strength of the fur side pelage with the skin tissue and strength of the fur at stretching.
