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.

SUBSTANCE: invention relates to machine building and may be used for producing braided gauzes. Proposed method comprises forming first unit helices by set of blades to preset length at preset pitch and expending them by expansion mechanism in helix axes to preset pitch defined by claimed relationship. forming second unit helices by second set of blades arranged opposite the first set at opposite side of produced gauze with shift relative to first unit helices through gauze pitch to ensure preset pitch in continuous rotation of helices. Said helices slide from blades to get braided into expanded helices of the first set to make gauze fragment. Length of said helices is selected appropriately. First unit helices are released from expansion mechanism and shifted to open the zone. Second unit helices are cut in said zone to cut finished gauze fragment to be displaced for connection with the next fragment. Gauze next fragment and connection helix are made, for the latter to be braided in the last helix of the next fragment and to the first helix of previous fragment over the entire length of all helices. Cycle is reiterated unless required length of gauze is produced.
EFFECT: production of fine gauzes.
