1. A system for stranding elongate filaments and cabling the stranded filaments into an elongate cable, said system comprising, in combination,a plurality of stranding modules each of which includes frame means defining a longitudinal axis and is adapted for end-to-end positioning with similar modules so as to establish a plurality of serially related stranding modules,each of said stranding modules further including flier guide means supported by the associated frame means for rotation about an axis substantially parallel to the longitudinal axis of the associated frame means,carriage means supported by each of said frame means interiorly of the associated flier guide means during rotation thereof, said carriage means being adapted to remain substantially stationary relative to said frame means during rotation of the associated flier guide means,at least two filament supply reels releasably mounted on each of said carriage means, each of said supply reels being adapted to support an elongate filament in wound relation thereon and being mounted on its associated carriage means so that the axis of each supply reel is substantially coaxial with the axis of rotation of the corresponding flier guide means,a plurality of guide rollers carried by each of said carriage means for receiving and guiding a filament from each of the corresponding filament supply reels to substantially the axis of rotation of a predetermined end of said carriage means,payoff flier means including a radially disposed flier arm operatively associated with each of said supply reels and having guide means at its radial outer end for guiding cooperation with the corresponding elongate filament so that said filament is paid out from the associated supply reel under substantially constant axial tension when the filament is subjected to an axial force sufficient to draw it from its associated supply reel,drive means independently operatively associated with each of said flier guide means for effecting predetermined rotation thereof relative to the associated frame means so as to strand the filaments from the corresponding supply reels to form a stranded filament at said predetermined end of each of said carriage means,second guide means carried by each of said flier guide means for guiding the corresponding formed stranded filament from said predetermined end of said carriage means to an outlet end of the associated frame means during rotation of said flier guide means, said outlet end being disposed longitudinally opposite said predetermined end of said carriage means,said carriage means including a carriage frame having axially extending support shafts affixed thereto and rotatably supported by the corresponding frame means, said support shafts being adapted to pass stranded filaments longitudinally therethrough to facilitate passage of stranded filaments between said serially related modules,each successive serially related module being adapted to helically strand at least two elongate filaments and guide the stranded filament to the corresponding outlet end thereof while simultaneously receiving any stranded filaments from the adjacent upstream module and guiding them to the corresponding outlet end while maintaining the stranded filaments in separated relation,and means positioned downstream of the last of said serially related stranding modules for cabling all of the strands from said modules.
