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 cord for reinforcing elastomers excellent in adhesion to elastomers such as rubber is provided. The cord is a cord for reinforcing elastomers (10) that includes metallic filaments (1) and a resin filament (2) twisted together, the resin filament (2) being made from a polymeric material having a melting point or softening point of 80 to 160° C. The cord for reinforcing elastomers includes a core and at least one sheath layer, wherein, after vulcanization, a distance w between metallic filaments (1b) forming an outermost sheath layer is 100 μm or less, and, on a cross section of the cord taken along a direction orthogonal to an axial direction, a filling ratio, which is a ratio of an area of a polymeric material (3) derived from the resin filament (2) to a gap region is 52 to 120%, where the gap region is defined as a portion occupied by a material other than the metallic filaments (1) within a region formed by connecting the centers of the individual metallic filaments (1b) constituting the outermost sheath layer.

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.

A machine for manufacturing cables includes a rotor tube inside which is a motor. The machine also includes four rods attached to the tube. The rods are arranged so as to follow secant lines of the wall of the tube and include two mutually parallel plates. Each plate is connected to the four rods. The four rods are arranged such that they exert a force on the wall of the tube towards the inside of the tube in order to compensate for the effect of centrifugal force. The motor is positioned between the plates.
