Ribbon tube production for high-count fiber optic cables
Your partner in fiber production technology
OFC 45 ribbon buffering line
Stable ribbon tube production
Ribbon-based fiber optic cables require accurate ribbon handling, stable tube dimensions, and controlled excess length. As ribbon counts increase, the process must keep ribbon tension, tube formation, jelly filling or dry tube calibration, cooling, and take-up conditions stable throughout production.
Ribbon buffering forms stable dry or jelly-filled ribbon tubes for central tube ribbon cables and high-count loose tube ribbon cable designs. The process helps create the controlled tube structure needed for reliable ribbon-based cable manufacturing.
OFC 45 Ribbon Buffering Line combines RST ribbon stranding, motor-driven tension-controlled ribbon pay-offs, ROEX tube extrusion, continuous jelly filling, vacuum calibration, relaxation cooling, and accurate process control to support stable ribbon tube production.
ribbon strander
Motor-driven, tension-controlled RST pay-offs reduce centrifugal forces and maintain accurate ribbon tension for stable excess length and high-yield production.
dry / jelly-filled
JFS 100 continuous jelly filling or NTA 1000 for lager swellable tape and VCU 30 vacuum calibration support controlled production of jelly-filled and dry ribbon tubes.
tube quality
Relaxation cooling, accurate tension control, and temperature control support stable tube dimensions, controlled excess length, and low post-shrinkage.
extrusion expertise
Built on Rosendahl’s extrusion expertise, OFC 45 uses ROEX extruders and NXH or RX crosshead solutions to form ribbon tubes with reliable material processing.
advantages of the OFC 45 ribbon buffering line
Controlled ribbon tube production for quality cables
Central tube and high-count ribbon cable designs
OFC 45 is designed for rollable and flat ribbon tube production used in central tube ribbon cables and high-count loose tube ribbon cable designs. Typical applications include gel-filled and gel-free central tube ribbon cables, as well as high-count loose tube ribbon cable constructions.
RST ribbon handling
The Ribbon Strander RST 300 supports controlled ribbon handling before tube extrusion. Motor-driven, tension-controlled ribbon pay-offs help maintain accurate ribbon tension, reduce centrifugal forces, support easy thread-up, and enable synchronized master/slave operation for stable production.
ROEX tube extrusion
OFC 45 uses ROEX extrusion to form the ribbon tube. The extrusion system supports stable output, operation-friendly adjustment, customized screw design, and reliable processing of materials such as PBTP, PVC, PE, HFFR, and PA12.
Dry and jelly-filled ribbon tubes
OFC 45 can produce jelly-filled or totally dry ribbon tubes. For jelly-filled tubes, the JFS 100 Jelly Filling System supports continuous filling, jelly hose heating, jelly recycling, and controlled filling conditions. For dry tubes, the VCU 30 Vacuum Calibration Unit supports stable and accurate tube dimensions with NTA 1000 applied swellable tape to prevent water penetration.
Relaxation cooling and tube stability
After extrusion, the tube must cool in a controlled way to maintain its shape and dimensional stability. The relaxation cooling zone supports low post-shrinkage and helps keep the tube stable without post-retraction. Together with vacuum calibration, tension control, and temperature control, it supports stable tube dimensions, controlled excess length, and repeatable ribbon tube quality.
Line stability and process control
OFC 45 can include modular cooling systems, diameter measurement, lump detection, entry and exit caterpillars, belt capstan, pneumatic dancer, tyre take-up, and LOS or PSU line control. These components support controlled production, stable ribbon tube quality, and reliable line operation.
