Secure core locking and extended paper-tube reuse. The ideal drop-in replacement for taper cones.
The MC-3 is a shaftless, lug-type mechanical chuck that grips from inside both core ends. It prevents end-face damage common with taper cones, eliminates air-shaft insertion and removal steps, and supports long-term reuse of paper tubes, contributing to a lower total cost of ownership. It also accommodates deformation at the core opening.
Key Features and Benefits
1. Easy retrofit, higher throughput
• Simple mechanism for quick changeovers.
• Secure, non-slip holding ensures complete core fixation and stable winding.
2. Broad core compatibility
• Large lug expansion range covers wide ID tolerance.
• Grip point set back from the end face for reliable clamping, even with end fittings.
3. Automation-ready, high-quality winding
• Shaftless, lightweight, compact body simplifies automated attach/detach.
• Surface contact rather than cone line contact improves torque transmission.
• Minimal runout supports high-precision, high-speed winding and unwinding.
