Continuous lug type air shafts are the most popular and versatile of the gripping types. They are the most economical, easiest and quickest to repair. Convertech has lugs available in aluminum for light weight, steel for rough jobs, and rubber for metal or plastic cores. Convertech continuous feature easy-to-repair components. There are no special banding tools or hydraulic presses required. Convertech continuous lug shafts feature a three-bladder system. Designed for medium to heavy-duty applications Convertech continuous lug shafts feature many standard parts and are very easy to repair.

PRODUCT UPDATE: With industry competition high, even small design improvements can make a dramatic difference in performance. Convertech's new GripLock™ lug design has increased core gripping power to improve roll quality and reduce core damage, while still keeping the shaft design efficient and effective.

Small improvements can make a big impact. Because roll quality is a major concern to converters, keeping cores locked firmly in place is a high priority. Air pressure in the air shaft is responsible for locking the lug in place on the core, but excessive air pressure can cause core damage, and too little air pressure will cause core slippage. Finding the optimal point between air pressure and lug grip is essential to creating the best finished rolls.

By changing their basic lug design to accommodate a variety of working environments, Convertech has taken the guesswork out of the process. Convertech GripLock™ lugs are designed to grip cores firmly, without causing core damage. All Convertech lug shafts and adapters feature GripLock™ lugs to ensure the best roll quality in a wide range of working environments.
