Product Overview:
Shaft Adapters – A Systems Approach              
Combine shaft adapters with pneumatic and mechanical chucks, which are designed for high-speed printing, laminating, and sheeting applications on unwind flying or zero-speed splicers and other shaftless unwind and rewind applications.
Benefits of converters:
•   Dramatically improve splice reliability.              
•   Increase operating speeds.              
•   Save time and money with repeated use of cores without damaging core ends, which can lead to excessive dust.              
Wide-footprint shaft lugs provide a consistent grip on the core, without damaging the inside. Removal is easy with pneumatic and mechanical retraction of lugs that ensure the lugs never stick to the core.              
Convertech’s Expanding Shaft and Chuck Adapters are available with your choice of:                           
•   mechanical or pneumatic expansions              
•   set screw or clamp collar designs 

Combine Convertech’s Mechanical or Pneumatic/Mechanical Chucks with our expanding adapters and you’ll be able to use more core diameters without purchasing additional shafts and chucks.
