FIELD: process engineering.

SUBSTANCE: invention relates to machine building and can be used at production of said elements used in vibration isolators and dampers. Proposed process comprises compaction of work pieces with plies of gauze woven from wire spirals stretched to pitch equal to spiral diameter and arranged perpendicular to stretching force acting at elastic hysteresis element. Portion of gauze plies are woven of right-hand lay spirals while another portion - of left-hand lay spirals, both with axes alternating in contact plies parallel with each other and perpendicular to acting stretching force. Pre-stressed gauze is used with one pair of contacting spirals elastically stretched and another one elastically contracted by the same load applied along spirals axes, said gauze being in elastic equilibrium. Said alternating gauze plies with aforesaid spirals are assembled to units wherein one unit includes spirals with axes perpendicular to one stretching force and another unit includes spirals with axes perpendicular to the other stretching force. Said unit alternate to make a workpiece wherein gauze plies contact with each other given they feature identical lay of spirals. Note here that the number of plies in different units is selected depending on stretching force perpendicular to axes of the unit spirals.

EFFECT: higher breaking point in two mutually perpendicular axes.
