NET WITH REDUCED BULK, ENHANCED ELASTICITY, REDUCED HYDRODYNAMIC RESISTANCE Russian patent published in 2006 - IPC D02G1/00 

FIELD: manufacture of fibers.

SUBSTANCE: the net includes the sides of the net mesh made of net weaving threads, which possess physical properties featured by meshes varying or alternating along the row of collinear sides (26). The nonhomogeneous medium obtained by formation of the net mesh sides by such a way, possessing variable physical properties, may be transformed for reduction or decrease of vibrations in the net, for example, of harmonic (resonance) oscillations. Besides, the net weaving threads, due to which the vibration is reduced, may be selected, which also results in reduction of material consumption required for manufacture of the net, which features the same strength or exceeds the strength of a common net of machine manufacture. Due to reduced vibration, the modified net has a longer service life in comparison with a common net of machine manufacture.

EFFECT: enhanced strength of the net, reduced probability to inflict injuries to fish escaping through the holes of the net meshes.
