Abstract
A net, in particular for protection, safety, water-rearing or architectural purposes, is braided together from individual helically curved longitudinal elements (3) to form a braided structure. Individual longitudinal elements (3) curved into a cylinder or screw shape are twisted one inside the other with adjacent ones and compressed such that the braided structure is in more or less planar sheet-like form and the longitudinal elements (3) here each form more or less rectilinear limbs (8a, 8b; 9a, 9b) and curves (10a, 10b; 11a, 11b) therebetween. The curves (10a, 10b; 11a, 1b) between elongate limbs (8a, 8b; 9a, 9b) are inflected in kink form. This gives a net design with unexpectedly high strength values.
