THREE-DIMENSIONAL NET Russian patent published in 2013 - IPC D03D1/00 

FIELD: metallurgy.

SUBSTANCE: three-dimensional net includes a number of layers adjacent to each other. Each layer is formed with two mutually orthogonal families of threads or rods. Axes of threads or rods have the shape of screw lines oppositely twisted in relation to axes of threads or rods of the other family, which are located so that each thread or rod of one and the same family on each turn envelopes the thread or rod of the other family and at the same time envelopes adjacent threads or rods of the family of its own. Threads or rods of each layer are twined with threads or rods of adjacent layers. A combined net is possible, which additionally includes separate threads or rods or those connected by means of conventional, for example, cloth intertwining, which are located in its cavities, as well as the net, in which screw lines of adjacent layers are characterised with n-fold differing pitch. When implementing the method, there can be achieved the technical result consisting in sufficient enlargement of application field of intertwining having an important advantage - high degree of connection of the obtained structure.

EFFECT: simplifying production process of the design and reducing the production costs.
