Operating range

  • For single and multi-core-usage
  • For any type of cores ≥ Ø 70 mm


  • Self-actuated permanent mechanical expansion for core-tightening
  • Variably expanded gripping jaws equalise the tolerances of the cores
  • Robust construction
  • Low maintenance
Characteristic features
  • Mechanical actuation by means of automatic spring-loaded gripping jaws
  • Mechanically-concentric expansion movement of gripping jaws by means of principle of incline
  • Various expansion of the sets of gripping jaws allows a take-up of multi-reels by equalisation of the existing core-tolerances
  • Pneumatic activation for the return movement of the expansion mechanism
  • Restricted reset of the gripping jaws
  • General, customized construction in modular design
  • Base material: aluminum, steel or special materials and CFK
