  • Patent number: 11124919
    Abstract: A strander apparatus includes a disk and a plurality of cradles, each of the cradles includes a reel and a cradle shaft, the cradle shaft extending in an axial direction from the disk. Each reel dispenses cable. The strander includes a main shaft, wherein the cradles are disposed on the cradle shafts radially about the main shaft. Planetary gears are disposed between the main shaft and the plurality of cradle shafts. The strander operates in one of a planetary mode and a rigid mode. In the planetary mode, while the main shaft rotates, the planetary gears are engaged to rotate each of the plurality of cradles on the respective cradle shafts. In the rigid mode, the planetary gears are disengaged.

  • Patent number: 6560954
    Abstract: A high-speed binder application device for wrapping binder material about a bundle of buffer tubes that contain optical fibers includes a pair of opposite facing binder heads mounted on a pair of hollow shafts, each shaft being driven in rotation by a concentric drive. Each binder head includes a light-weight synthetic guide drum that dispenses binder material from a reel and onto the bundle of buffer tubes as it is advanced through the hollow shafts. The lightweight and high strength of the synthetic guide drums allows the drums to be rotated at speeds in excess of 4000 RPM. Each drive is concentrically mounted on its respective shaft which reduces or eliminates the shaft bending loads associated with prior belt-driven binder devices, and thus reduces vibrations at higher rotational speeds.

  • Publication number: 20020157374
    Abstract: A high-speed binder application device for wrapping binder material about a bundle of buffer tubes that encase a plurality of optical fibers includes a pair of opposite facing binder heads mounted on a pair of hollow shafts, each shaft being driven in rotation by a concentric drive motor mounted about the shaft. Each binder head includes a light-weight synthetic guide drum that dispenses binder material off a reel and onto the bundle of buffer tubes as it is advanced through the hollow shafts. The concentric mounting of the drive motors on the shafts eliminates shaft bending loads from drive belt tension and reduces vibrations at higher rotational speeds relative to belt-driven systems. The light weight and high strength of the synthetic guide drums allows the drums to be rotated at speeds in excess of 4000 RPM.

  • Patent number: 5826419
    Abstract: An apparatus and method for manufacturing fiber optic cable having a plurality of optical fiber buffer tubes bound by a binder is provided. The apparatus includes a frame and an oscillator shaft support on the frame for oscillating movement about a longitudinal axis. A lay plate is carried by the oscillator shaft and has a plurality of openings for receiving and guiding longitudinally advancing buffer tubes into an oscillating lay about the axis. First and second longitudinally offset binder heads are mounted for rotation about the axis for winding respective binders around the buffer tubes. Both binder heads are concentric with and surround the oscillator shaft such that the closing point for the buffer tubes is downstream of the binder heads and closely adjacent to a locking capstan. The rotatably supported ends of the binder heads are positioned adjacent to each other which allows improved replacement of binder reels.

  • Patent number: 5372757
    Abstract: A loose tube element including a plastic sheath containing a grease-like material and an optical fiber or bundle of optical fibers or a ribbon of optical fibers is pulled from an extruder crosshead through a cooling bath and around a constant speed capstan. The loose tube element travels around the constant speed capstan a number of times and as it exits the capstan it is subject to a tensile force provided by a variable torque control capstan. The tensile force causes elongation of the plastic sheath, causes the optical fiber to be pulled taut and thereby controls the ratio of fiber length to sheath length within the loose tube element. While subjected to the tensile force, the element is subsequently cooled, causing the elongation of the plastic sheath to become permanent and thus fixing the fiber-to-sheath length ratio.
