RUBBER-CORD ELEMENT Russian patent published in 2019 - IPC F16L33/22 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of rubber-cord compensating elements of pipelines for transfer of fluids at high pressure and can be used in production of flexible hoses, as well as in production of pneumatic rubber-cord elastic elements of damping and vibration isolation systems of equipment and articles for various purposes. Toroid-shaped bead ring is equipped with butt-end projections, between which one metal-rope is laid in the form of a synthetic rope from different layers of the power frame, at that, the metal-ropes do not intersect each other, as well as comb protrusions, between which there are ends of metal-ropes, and holes for passage of metal-ropes in continuous flow are located in one row with equal distance between centers of holes.

EFFECT: high strength, reliability, as well as reduced weight and size parameters of the rubber-cord element.
