flexible shock cords have a heart of latex threads. Depending on the intended purpose of the rope, the required quality of the latex threads is determined by their predefined stress-strain behaviour. The latex heart threads run into the braiding with a significant degree of pre-tension. The elastic rope is produced in its fully extended state and becomes shorter as it exits the machine to finally settle at its output length. Double braiding sheathing the elastic heart provides it with soft and reliable surface protection against external influences.
