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: With an apparatus for the shock absorption of rope structures, in particular for rockfall, land slide and snow barriers, at least one intermediate piece (1; 1?) deformable by tensile forces is provided which is accommodated within a rope subjected to tension. The intermediate piece (1, 1?) comprises one or more longitudinal elements (7, 8, 20) which can respectively be in the form of a strip, bar, wire, rope and/or strand. The longitudinal element or elements (7, 8, 20) are connected by their one end (7a, 8a; 20a) to the one rope end. On the other hand, they are guided about a deflection element (10; 10?) connected to the other rope end. Means are provided by means of which the deflection angle of the longitudinal element or elements formed upon loading the intermediate piece (1, 1?) is substantially sustained. The shock absorption characteristics can thus be better defined and optimised.

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: In a method for lining tunnel walls or ceilings with protective nets or the like, web-shaped protective net material is unwound from a reel and is fastened to the tunnel walls or ceiling by tie bolts. The reel is rotatably arranged. The rotation of the reel about a shaft is controlled in order to unwind the protective net material, the shaft being mechanically moved in steps along the tunnel walls or ceiling together with the reel. The protective net material unwound in each step is preferably stretched and mechanically fastened. The individuals carrying out these processes are thus not exposed to any direct risk, while the lining process can be accelerated.
