FIELD: machine building.
SUBSTANCE: group of inventions relates to sealing equipment. A seal includes a polymer cuff fixing the seal surface and an inner cavity located inside the polymer cuff along the polymer cuff. The seal also includes a spring extending within the inner cavity and containing a lot of spring elements cut with a fibre laser. The seal can be located between a fixed element and a rotating element. The seal formation method is described.
EFFECT: technical result consists in an improvement of reliability of a seal due to manufacturability of the seal springs.
