Abstract: Netting (15) includes mesh bars (26) made from twines (11, 13) which possess physical properties that vary, change or alternate along a series of collinear mesh bars (26). The non-homogeneous media obtained by arranging in this way mesh bars (26) having varying physical properties may be configured to dampen or attenuate vibrations in the netting (15) such as harmonic oscillations (resonance). Furthermore, twines (11, 13) that attenuate vibrations may be chosen that also reduce the amount of material required to make netting (15) which has strength similar to or greater than conventional machine-made netting (15). Due to reduced vibration, the improved netting (15) lasts longer than conventional machine-made netting (15), and reduces the possibility of injury to fish which escape through a trawl's mesh cell openings.

Abstract: An automatic weaving process for the manufacture of rope hammock beds in which a bobbin of rope passes through loops of rope from the same bobbin resulting in a traditional weave (FIG. 1) from one continuous rope. The process and machine create a woven, open mesh pattern of rope or like materials for forming articles, such as hammocks. The means comprise a frame having a plural set of opposed reciprocal rods, each having a pulley-shaped or like structure mounted on their opposing ends. The frame also supports a means for attaching one end of the rope, and a set ofpulleys to each side centrally, but laterally movable to the rods.

Abstract: A net comprises a border member defined by at least a first border section and a second border section each extending generally orthogonally to one another and having a plurality of weft members each connected to one of the first and second border sections and being disposed in a first given direction. The net includes a plurality of warp members each connected to the other of the first and second border sections and being disposed in a second given direction generally oriented orthoganally to the first given direction. The weft and warp members being crossed with one another in a single common plane and in a manner which causes the members to be locked against relative axial and twisting movement. Each of said weft and warp members being a hollow braid member capable of being transversely pierced by the other such member.

Abstract: A knotting method for a netting is disclosed which comprises the steps of seizing together a warp yarn which is paid out from a creel stand and a weft yarn which is paid out from a shuttle to form substantially concentric loops which are opposite in yarn feed direction to each other, pulling out the warp yarn upstream of the loop with respect to a feed direction of the warp yarn through the concentric loops to the opposite side, causing a weft supply side where the weft yarn is paid out to pass through a loop which is formed by the warp yarn as pulled out through the concentric loops, and tightening the warp and weft yarns which are intertwined. The resultant knot is firm and very small.

Abstract: A mesh structure comprises intersecting elongate members with each node at which they intersect being on the boundaries of four apertures in the mesh structure. One of said members has a locus which first defines the boundary between a first of said apertures and a second of said apertures, then transits said node and defines the boundary between a third of said apertures and the fourth of said apertures. The other of said members has a locus which first defines the boundary between said second and said third apertures, then transits said node and defines the boundary between said fourth and said first apertures. Said loci or said one member and said other member while transiting said node have such configurations that said members are knotted together.

Abstract: The invention relates to square-meshed net, and method and machine for knotting the same. In knotting a net using upper hooks arranged in a line, warp is arranged in opposition to the upper hooks and knotted to weft by the same upper hook as that in opposition to warp, and weft is transferred in one cycle of the knotting to next upper hook in a prescribed direction and knotted to warp by the next upper hook. In knotting a net using upper hooks arranged in circular form, warp (or weft) is knotted to weft (or warp) by the same upper hook as that in opposition to warp (or weft), and weft (or warp) is transferred in one cycle of the knotting to next upper hook in a prescribed direction and knotted to warp (or weft) by the next upper hook. Warp and weft are perpendicular to each other at the unfolded state and rectangular meshes are constituted. In some case, weft is turned twice and constitutes S-shaped loop.

Abstract: Improved structural nets for cargo and the like are formed on a fixture including a knot forming matrix including a plurality of knot loop stations arranged in a predetermined orientation and cooperating with loop forming section disposed peripherally of the matrix. By forming a plurality of knot loops in sequence in a plurality of rows, each of which is in a predetermined x-y orientation, the manipulative operations for forming a plurality of hand tied knots is simplified. An inserted tension member is fed through each of the knot loops and the latter are tightened to form knots at the crossing point of the tension members.
