Abstract: A net is particularly suitable for a basket for pisciculture, which may be placed in sea or fresh water. The net is made of a wire material, producible from individual spiral or similarly bent longitudinal elements, wherein adjacent threads are woven together. The net is simple and economical to produce, for example, by threading each longitudinal element into engagement with another longitudinal element while it has a shape of a spiral or screw to thereby provide it with a cylindrical form, and compressing each longitudinal element, when having the cylindrical form and after being threaded into engagement with the another longitudinal element, to provide the longitudinal element with substantially straight wire sections. The threading and compression steps are repeated to form a net after compression of several longitudinal elements threaded to one another.

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.

Abstract: According to the invention, a security net can be erected in or on water or on the ground and is provided with a net or net-like structure (1) manufactured substantially from wire material, rope material, strand material or plastics material (2). The net (1) is bent together and forms longitudinal flanks (3, 4) and at least one arched region (5). The overlapping longitudinal flanks (3, 4) can be connected together and several stabilizers (8) are associated with the net (1). In cross-section, the net (1) is constructed similarly to a teardrop, with the arched region (5) lying on or at least partially in the water. In this way, a largely double-walled security system is obtained, which is able to intercept impacting objects reliably and moreover gently, because the net and the three-dimensional protective net structure is deformable due to the relative flexibility thereof.

Abstract: A net (11) is particularly suitable for a basket for pisciculture, which may be placed in sea or fresh water (16). The net (11) is made of a wire material (1), producible from individual spiral or similarly bent longitudinal elements, wherein adjacent threads (2, 3, 4, 5) are woven together. Said net is simple and economical to produce.

Abstract: The invention concerns an obstruction device for flowing waterways and rivulets of all kinds, in particular for torrents and similar river beds, with a flexible barrier element in the form of a catchment net (4), extending from one riverbank (2) to the other riverbank (3) transverse to the flow direction (7). The catchment net (4) is installed between a lower support rope (5) and an upper support rope (6). The support ropes (5, 6) are anchored in the riverbanks (2, 3) with rope anchors (8, 9) attached to their ends, whereby the rope anchors (9) of the upper support rope (6) are offset to the front relative to the rope anchors (8) of the lower support rope (5) in flow direction (7). In this way the catchment net (4) can deform itself when the barrier is filled in such a way that the water, rocks, flotsam etc. then overflowing the net will contact the same either not at all, or only briefly. In this way it is safely and permanently protected against the corrosion and abrasion effect of the overflowing water.

Abstract: A protective net, especially for rockfall protection or for verge securing, with a diagonal weave (10), is formed by a three-dimensional mattress-like structure. The same is woven from individual spiral-shaped bent wire strands, wire bundles, wire cables (11, 12, 13, 14) or suchlike, which incorporate two or more wires (22) or wire strands made of steel. It is of great advantage if the wire strands, wire cables, or wire bundles or suchlike are made at least in part from high tensile steel, and if the protective nets can therefore be equipped with very great strength.

Abstract: A protective mesh, especially for rockfall protection or to stabilise a layer of soil, is braided out of helically curved wires (11, 12, 13, 14, 15, 16). Rhomboidal meshes (17) are formed and in each case two adjacent helical wires (11, 12, 13, 14, 15, 16) are flexibly held together. The protective mesh (10) has a thickness which amounts to a multiple of the thickness of the wire. In at least some of the braided pairs of wires (11, 12, 13, 14, 15, 16), an essentially straight longitudinal reinforcement element (31, 32, 33, 34, 35) is guided through the coupling area (A) of the two helical wires, causing the rhomboidal meshes (17) to be divided into triangular meshes (17a, 17b). In these crucial areas of force transmission of the protective mesh, there are now three instead of two wires meeting, as the result of which the force absorption capacity of the protective mesh is substantially increased.

Abstract: In a method for the production of a safety net consisting of intermeshing rings (1), a wire (2) is inserted in approximately its axial direction and shaped by bending into a ring (1) with several windings. While being fed through, the wire (2) is passed through two elements (3, 4) each provided with a through-opening (4?) and fully enclosed, and bent more or less into a ring (1) and, with each winding, is fed through these elements (3, 4), until the through-opening (4?) of these elements (3, 4) is more or less filled with wires (2). This ring (1) withstands loads better, while at the same time being simple to produce and the wire loops are additionally more consistently held together in a ring.
