  • Patent number: 6247298
    Abstract: A fabric (144) for use as a stab-resistant insert in protective textiles comprises a plurality of steel cords (100). Each of the steel cords (100) comprises a longitudinal axis (102) and two or more steel filaments (104). Each of the steel filaments (104) forme a twisting angle &agr; with the longitudinal axis (102) of the steel cord (100). The steel cords (100) have two or more of such twisting angles which are substantially different from each other so that any penetrating stab or knife is stopped.

  • Patent number: 4887656
    Abstract: A bias weave fabric wherein the weft elements (2) have a tensile modulus of at least 30,000 N/mm.sup.2 and the angle .alpha. between warp (3, 4) and weft (9) is between 10.degree. and 85.degree. whereas the packing factor (b/c) is between 30% and 90%. A process and apparatus for transforming a regular weave fabric (11) to a bias weave fabric is also covered whereby the regular fabric is guided in a zig zag path between a set of rollers (22a-22b) crosswisely arranged in a frame (20).

  • Patent number: 4650068
    Abstract: A flat reinforcing structure for elastomeric objects such as conveyor belts comprises a first series of parallel cords covered on one side by a second series of parallel cords which with respect to the first series are transversely disposed and whereby the cords are mutually connected at the intersections. The nominal tensile strength of the first series of cords per unit width is at least twice the nominal tensile strength of the second series of cord per unit width. The tensile strength of each cord of the first series is at least one and at most ten times the tensile strength of each of cord of the second series. The cords are preferably steel cords.

  • Patent number: 4623281
    Abstract: Disclosed is a dimensionally stable, flexible and open-mesh woven fabric comprising a warp and a weft comprised of thread-like elements, wherein the warp elements are arranged in groups spaced apart from each other, wherein the distance between each two successive groups as well as the distance between each two successive wefts is between about 0.8 cm and 6 cm, and wherein the clamping force of a group of the warp elements on the weft elements is such that an axial movement of the weft elements occurs only in the case of an axial tensile loading of at least about 1% of the breaking strength of the weft elements.
