    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.

  • Patent number: 8042598
    Abstract: An insect screen of increased invisibility can be created by using small wire diameter elements and/or increasing the mesh density of the screen. The combination of small wire diameter and increased mesh density provide a screen with a higher Dalquist Rating that becomes invisible at closer distances. A “sweet spot” exists at which a screen with a combination high mesh density and small wire diameter is less visible, while still providing the strength, durability, and quality desired. Further, screens with properties in proximity to this sweet spot also provide a marked increase in invisibility.
