Operating range

  • When there is a need for concentricity and winding processes with high loads
  • Compatible with automatic usage
  • For any type of cores ≥ Ø 150 mm
  • For a take-up of thin and sensitive cores

Characteristic features

  • Flexible protective covering for a higher grip and concerted prevention against the ingress of impurities
  • Low maintenance
  • Easily pneumatically actuated
  • Mechanically-concentric expansion for reel take-up
  • Robust construction fa a long serviceable life
  • Exceptionally core-friendly
Characteristic features
  • Pneumatically generated pushing force by means of pneumatic cylinder or pneum.-hydr. amplifier
  • Mechanically-concentric expansion movement of the protective covered expansion segments by means of principle of incline
  • Spring-assisted restricted reset of the covered expansion segments
  • Exchangeable protective-covering made of polyurethane
  • Base material: steel or special materials
