An apparatus for producing an assembly of filamentary elements that are wound together in a helix includes a twisting device, a preforming device, and an assembling device. The twisting device is structured to twist at least first and second filamentary elements individually, such that each filamentary element is twisted separately from another filamentary element, to produce at least first and second twisted filamentary elements. The preforming device, which is arranged downstream of the twisting device, is structured to preform each of the twisted filamentary elements individually into separate preformed helixes, to produce at least first and second preformed helixes. The assembling device, which is arranged downstream of the preforming device, is structured to assemble the preformed helixes into an assembly.

A bicycle control cable is provided with a central wire and at least one resin string. The at least one string made of resin is spirally wound onto the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire with a pitch less than or equal to 1 millimeter. The at least one resin string defines a spiral gap between adjacent windings of the at least one resin string. The at least one resin string defines an outer sliding surface for reducing a sliding resistance of the central wire. The central wire and the at least one resin string define an inner wire configured to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.

The invention refers to a rope (3) made of a textile fiber material, comprising a rope core (6) as well as a sheath (7) surrounding the rope core (6), wherein the rope (3) comprises at least one antistatic multifilament yarn (5) or antistatic monofilament that is located in the rope core (6), in the sheath (7), in an intermediate sheath (8) located between the rope core (6) and the sheath (7) and/or in a reinforcement located between the rope core (6) and the sheath (7),

wherein the antistatic monofilament or individual filaments (12) of the antistatic multifilament yarn (5) each comprise a conductive fiber core (13) sheathed with a non-conductive plastic sheath (14), and wherein the at least one antistatic multifilament yarn (5) or antistatic monofilament is twisted with a twine (16) or yarn of a different material, wherein the other material of the twine (16) or yarn mentioned is preferably UHMWPE or PES.

A steel strand (10) comprises a steel core wire (12). This steel core wire (12) is surrounded by steel layer wires (14) that are twisted around the steel core wire (12). The steel core wire (12) is covered with a thick corrosion resistant core coating (16) provided by strip cladding or by metal extrusion. The steel layer wires (14) are covered with a thin corrosion resistant layer coating (18) provided by a hot dip operation or by an electroplating or chemical plating process. The steel strand (10) is compacted so that said steel layer wires (14) have a non-circular cross-section and that the thick corrosion resistant core coating fills the interstices between the steel core wire (12) and the steel layer wires (14) in order to give the steel strand (10) an improved corrosion resistance and increased lifetime.
