Anti Torsion Braid

In most flexible handling cables, we use an anti-torsion braid. The anti-torsion braid consist of synthetic threads with a very high tensile strength. It is embedded between inner and outer sheath to prevent twisting, loops, push off the outer sheath and “corkscrew-effects”.

Torsional stresses is caused by different conditions:

• Changes of direction into different planes
• Non aligned guide pulley
• Sloping cable guide into the deflection pulley
• High dynamic stress
• High tensile load of the cable

Criterias to build up a heavy duty reinforcement:

• A good chemical bonding between synthetic threads and sheath compound
• Braid angle
• Braid coverage percentage
• Material of reinforcement
• Shear resistance of the reinforcement element
