COMPACT NON-DELAMINATING METAL CORD Russian patent published in 2005 - IPC

FIELD: manufacture of products from metal threads, in particular, compact non-delaminating metal cord used for reinforcement of technical rubber articles.

SUBSTANCE: metal cord has dense structure preventing fabric from breaking and delamination of upper wires upon bending of structure, which might occur during processing of articles. Compact non-delaminating metal cord, preferably for reinforcement of rubber articles, has central structure - core consisting of one-five wires, outer wire layer enclosing said core, and one or two intermediate layers. Core wire coiling pitch and direction of intermediate and outer layers are identical. Length of wire coil of outer metal cord layer after it is plaited increases by 0.1% so that wires in metal cord create tensile force oriented along wire. Value of tensile force is such that metal cord does not delaminate during processing of article manufactured therefrom.

EFFECT: increased efficiency and improved properties of metal cord and products manufactured with the use of said metal cord.
