PROTECTIVE NET, IN PARTICULAR FOR PROTECTION AGAINST FALL OR FOR SLOPE REINFORCEMENT AND METHOD OF ITS MANUFACTURING Russian patent published in 2009 - IPC B21F27/02 E01F7/04 E02D17/20 E04H17/02 

FIELD: agriculture.

SUBSTANCE: invention is related to protective nets, intended for reinforcement of slope against fall, and to methods of their manufacturing. Net is made with diagonal plaiting and is woven of twisted wire strands bent in the shape of spirals, armature bundles or cords, which comprises two or more wires or twisted wire strands of steel. Method for manufacturing of protective net consists in the fact that twisted wire strand, cord or armature bundle is fed with a certain angle of lift at least to one bending mandrel of device and is bent at a certain length around bending mandrel approximately by 180°, then repeatedly moved along their longitudinal axis to bending mandrel at a certain length, bent accordingly around bending mandrel by 180° until this twisted wire strand, cord or armature bundle does not achieve shape of spiral, besides wire strand bent in the form of spiral, cord or armature bundle are woven together with the second twisted wire strand, cord or armature bundle bent in the form of spiral, and this is repeated until net is made with diagonal plaiting of desired value.

EFFECT: optimal fixation of slope is achieved, as well as damage danger is reduced.
