MANUFACTURING METHOD OF FLAT GASKETS, AND FLAT GASKET ITSELF Russian patent published in 2012 - IPC F16J15/08 

FIELD: machine building.

SUBSTANCE: method of mechanical connection of flat gaskets having at least two layers consists in the fact that individual layers are arranged in area of working tool, and at least one puncheon with almost round cross section partially cuts the layers in certain places of the corresponding area of connection, and at least some parts of the rest material are deformed outside the corresponding cut, thus forming bent areas; at that, they are formed so that the corresponding cut area is rounded and the appropriate bent area is straight-line. Sharp edges at least of one of the layers, which are formed in the cut area, are connected to material at least of another layer in order to obtain the connection by means of clamping, but with possibility of its release.

EFFECT: invention simplifies manufacturing process of flat gaskets.
