Method and apparatus for twisting filaments to form a cable

An apparatus for twisting a plurality of filaments on an advancing core to form a cable comprising:

• a. a reel mounted for rotation about an axis and having a group of side-by-side filaments wound thereon;
• b. a flyer mounted for rotation about said axis so that it travels around said reel, said flyer engaging said group of filaments and being operable for unwinding said group from said reel;
• c. means for rotating said reel about said axis;
• d. means for rotating said flyer about said axis in the same direction as said reel and at a speed which causes said group to be unwound from said reel by said flyer;
• e. gathering means rotating with said flyer about said axis, said core passing axially through said gathering means, said filaments passing to said gathering means from said flyer, said gathering means aligning different filaments of said group in different spaced positions around said core and twisting said filaments around said core to form said cable;
• f. means for drawing said cable from said gathering means;
• and
• g. means for controlling and adjusting the rotational speed of said flyer relative to the rotational speed of said reel to achieve a substantially uniform number of rotations of said flyer per unit length of said cable.
