Round Braids

  • The strands are wound like propellers but in opposite direction.
  • The winding pitch determines flexibility.
  • Advantage : extreme flexibility, more flexible than braids of equal cross sectional area and than single stranded wires: when this type of braids is cut the strands do not separate.
    Flexible in all directions.
    Resists torsion to the point that the strands do not widen.
    Square or rectangular sections with round edges can be obtained, with a good flat flexibility.
  • Disadvantages : not a perfect cylinder.
    Great lengths cannot be obtained, higher costs with respect to the braid type.
