Description

Air Shafts are the industry standard for rapidly and securely mounting paper or plastic cores onto unwinding and rewinding stations. By injecting compressed air into a centralized bladder, exterior lugs or leaves expand outward, biting into the inside of the core to provide a slipless torque grip. When deflated, the lugs retract instantly, allowing the heavy roll to be slid off the shaft effortlessly, reducing operator fatigue and slashing roll changeover times.
