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. Backed by decades of experience in unwinding and rewinding technology, PNEUMATIC INDUSTRIES CO., LTD. delivers proven reliability and long service life.
