Cable Capstan Unit

The Cable Capstan Unit, an essential component in wire and cable extrusion lines, functions as a high-precision haul-off device to uniformly pull the insulated or jacketed product from the extruder head. It typically uses a flat belt or dual-caterpillar tracks with pneumatic clamping to ensure consistent traction without deformation. Equipped with a DC or variable frequency drive for stepless speed regulation, the capstan maintains precise line speed and tension, often monitored by a laser micrometer for diameter control. Available in various models with traction forces up to thousands of kilograms and speeds over 100 m/min, it guarantees continuous, stable production for a wide range of cable sizes.
