A multilayer strand steel wire rope production device is provided. A pre-former is fixed on a drum, and a specific position of the pre-former is defined, a center strand payoff spool and a plurality of outer winding strand payoff spools are provided in the drum. The first wire guide mechanism is close to the corresponding outer winding strand payoff spool. One end of the outer surface of the drum away from the first wire guide mechanism is provided with a second wire guide mechanism, and a hub is additionally provided and located on one side of the drum close to the second wire guide mechanism; outer winding strands drawn from the plurality of outer winding strand payoff spools sequentially pass the first wire guide mechanism, the pre-former, and the second wire guide mechanism, and are guided to the hub for gathering to complete strand wire twisting.

A braiding apparatus for forming braided tubing comprises a braiding wheel and a plurality of bobbins. The plurality of bobbins are configured to move circumferentially around the braiding wheel. Each bobbin includes a spool, a first pulley assembly, and a second pulley assembly. The spool is configured to hold a tow formed from a braiding material. The first pulley assembly is coupled to the spool at a first distance from the spool. The first pulley assembly is configured to facilitate passing the tow over a pulley of the first pulley assembly. The second pulley assembly is coupled to the spool at a second distance that is less than the first distance. The second pulley assembly is configured to facilitate receiving the tow from the first pulley assembly and passing the tow over a pulley of the second pulley assembly and towards a section of the braiding apparatus at which a plurality of tows come together to form the braided tubing.
