These air shafts ensure consis- Available 70mm to 10\" diameters tent tension across all rolls, making them perfect for multiple- width rolls and materials on the same air shaft. Face lengths up to 150\" Recent advances in our Differential shaft design have taken the Slits from 1/2\" wide and up pain out of differential winding. An internal clutching mechanism controls tension to eliminate operator error and dramatically im- prove roll quality. The integrated GlideLock rollers allow easy loading and unloading of heavy rolls.

All Convertech Continuous Lug shafts and adapters feature GripLock™ lugs to ensure the best roll quality in a Aluminum or steel bodies wide range of working environments. Lightweight aluminum bodies available Aluminum, Steel, or Urethane lugs Convertech’s GripLock™ Lug design has increased the core gripping Centering version available power of our Continuous Lug shaft to improve roll quality and reduce core damage, while keeping the Continuous Lug shaft design efficient and effective. MORE ABOUT THE CONVERTECH CONTINUOUS LUG – AIR SHAFT Continuous Lug type air shafts are the most popular and versatile gripping type, because they are the most economical, easiest and quickest to repair. Convertech has lugs available in: • Aluminum for light weight • Steel for rough jobs • Urethane for metal or plastic cores Convertech Continuous Lug shafts feature easy-to-repair components. No special banding tools or hydraulic presses are required. Convertech Continuous Lug shafts feature a three-bladder system. Designed for medium- to heavy-duty applications and easy to repair, Convertech Continuous Lug shafts feature many standard parts. With industry competition high, even small design improvements make a dramatic difference in performance. The increased core gripping power of Convertech's GripLock™ lug design improves roll quality, reduces core damage, and keeps the shaft design efficient and effective. Roll quality is a major concern to converters, and keeping cores locked firmly in place is a high priority. Air pressure in the air shaft locks the lug in place on the core, but excessive air pressure can cause core damage, and too little air pressure will cause core slippage. To create the best finished rolls, it is essential to find the optimal point between air pressure and lug grip. Convertech has taken the guesswork out of the process and changed their basic lug design to accommodate a variety of working environments. Convertech GripLock™ lugs are designed to firmly grip cores without causing core damage. All Convertech lug shafts and adapters feature GripLock™ lugs to ensure the best roll quality in a wide range of converting applications. 3

Table of Contents LEAF STYLE - AIR SHAFT EXPANDING LEAF AIR SHAFT Availability: 2-3 Weeks - Made in the USA Available in four styles: Small diameter, wide web, narrow web, and heavy duty Fixed leaves available Leaves assure uniform expansion of thin walled cores PRODUCT SPECIFICATIONS PRODUCT OVERVIEW 1” to 12” diameters (other diameters available) Leaf-type air shafts are usually the most expensive and heaviest type of expanding air shaft. Convertech Leaf Air Shafts are lighter than other Face lengths up to 150” leaf shafts. Convertech’s Leaf Shaft is recommended for use with thin walled cores, and well suited to narrow cores on slitters. Generally, a leaf shaft should not be used as a “differential type shaft” on slitters. UNIFORM EXPANSION REDUCES WASTE AND SAVES CORES Advanced integration of high-quality materials ensures Convertech’s Leaf shafts grip firmly and expand precisely. Anodized aluminum leaves expand uniformly along the entire length of the Leaf shaft, assuring a firm grip and precision control of roll concentricity. Best suited for use with: • Thin-walled paper • Steel • Plastic • Fiber cores Convertech’s Leaf shaft is available in core diameters ranging from 1 to 12 inches, and face lengths up to 150 inches. MORE ABOUT THE CONVERTECH LEAF STYLE – AIR SHAFT Featuring a simple interlocking extrusion leaf, this air shaft is well-suited to light and medium-duty narrow web applications. Leaf-type air shafts are usually the most expensive and heaviest type of expanding air shaft. A Convertech Leaf shaft is less expensive and lighter than other leaf shafts. Recommended for use with thin walled cores, the Convertech Leaf shaft is well suited to narrow cores on slitters. All cores must have identical inside diameters for this type of shaft. If different diameters are mixed, substantial core slippage may occur because the leaves cannot conform to the different dimensions. A leaf shaft should not be considered for use as a \"differential type shaft\" on slitters. 4

Table of Contents LUG TYPE - AIR SHAFT PNEUMATICALLY EXPANDING LUG SHAFT Availability: 2-3 Weeks - Made in the USA Reduce your repair time to 10 minutes or less, all with common hand tools QuickChange(TM) Bladder Cartridge design ensures easy repair Button type expanding lug shafts Delivered faster than Tidland lug shafts PRODUCT SPECIFICATIONS PRODUCT OVERVIEW Face lengths up to 150” Reduce your lug shaft repair time to as little as 10 minutes, all with common hand tools Aluminum or Steel shaft bodies Designed with the operator in mind, QuickChange™ Bladder Repair Cartridges are Aluminum or Steel lugs unique features of Convertech Lug Shafts. Each QuickChange™ Bladder Repair Car- tridge is an all-inclusive repair part that can be kept in stock inexpensively - much less expensively than the time lost during a typical lug shaft bladder repair. Using only common hand tools, such as pliers and hex wrenches, an operator can remove the old bladder cartridge, install, and position the replacement in ten minutes or less. No special banding tools or hydraulic presses are required. Ensure maximum uptime by keeping a spare bladder cartridge as a backup. Lug shafts are the most popular and versatile of the gripping types, because they are the most economical, easiest, and quickest to repair. MORE ABOUT THE CONVERTECH LUG TYPE – AIR SHAFT The cumbersome nature of expanding bladder removal and replacement typically makes lug shafts time-consuming and difficult to repair. Lug shaft repairs usually cause significant downtime because they often require specialized tools, extensive disassembly and reassembly, and time-consuming procedures to insert and position the replacement bladder. Convertech's QuickChange™ Bladder Repair Cartridges eliminate many common issues associated with lug shaft repair, which dramatically eases the bladder repair process. QuickChange™ Bladder Repair Cartridges are designed with the operator in mind. Each QuickChange™ Bladder Repair Cartridge is an all-inclusive repair part that can be kept in stock inexpensively—much less expensively than the time lost during a typical air shaft bladder repair. An operator can use common hand tools like pliers and hex to quickly remove the old bladder cartridge and easily insert and position the replacement in as little as ten minutes. The ease of repairing an air shaft bladder will dramatically reduce downtime and increase overall productivity. Each QuickChange™ Bladder Repair Cartridge is completely interchangeable with all others of the same diameter and length, so identical shafts on different machines can share a common stock of replacement cartridges. The QuickChange™ Bladder Repair Cartridge system unifies the production environment, ensures quick replacement of bladders, and provides maximum uptime. 5
