Lightweight Expanding Carbon Fiber Shafts

Dura-Light Carbon Fibre Shafts:

Dura-Light Carbon Fibre Shafts are lightweight winding shafts.

They replace heavy steel shafts without sacrificing strength or stiffness.

1	Carbon fibre shafts have stainless steel air valves that will not corrode.
2	Easy-access journal fastening system (no press fit).
3	Gripping lugs.
4	Proprietary corded polyprene bladder material minimizes bladder shaft failure and subsequent maintenance.
5	Carbon fibre shaft housing can provide stiffness and strength equal to steel at a fraction of the weight.
6	Metal sleeve protects carbon fiber shaft housing from abrasion.
7	Hardnened steel journals custom made for your machine.

Lightweight Carbon Fibre Shaft ~ Features, Advantages, and Benefits

Feature	Advantage	Benefit
Carbon Fibre Shaft Housing Moduli: Standard (33 million) Ultra-High (57 million) Ultra-Ultra-High (78 million)	Lightweight. Better ergonomics.	Fewer shaft handling injuries lower worker’s compensation expenses and non-productive time. Meet regulations for single person lifting.
	Less deflection.	Reduced vibration and less roll bounce. Heavier roll weights.
	Higher critical speed.	More throughput.
Protective Outer Sleeve	Protects carbon fibre shaft from abrasion.	Longer carbon fibre shaft life.
Proprietary Bladder	Stretches less than traditional rubber.	Dependable lug collapse ensures consistent, easy removal of shaft from spent cores.
	More resistant to heat, punction, and abrasion.	Far less bladder failure and minimized maintenance.
Springless Lugs	No springs to break and puncture bladder.	Longer bladder life; less maintenance.
	Diamond pattern gripping surface with large surface area.	Better grip with less slipping.
Custom Journals	No press fit facilitates journal removal.	Bladder replacement, though rare, is quick and easy.

The Double E Company...

Introduced carbon fibre shafts to the paper, film, and foil converting industries in 1986.
Has manufactured more lightweight carbon fibre shafts, for more applications, than all other shaft producers combined.
Offers the longest, most comprehensive warranty on all of its carbon fibre shafts and carbon fibre rollers.
Winds and cures its own carbon fiber shafts in a state-of-the-art facility for strict quality control and fast lead times.

Dura-Light Non-Expanding Carbon Fibre Shafts (Through Shafts)

Used with core chucks to provide a lightweight shaft assembly (Double E manufactures a complete line of lightweight and durable core chucks).

Dura-Light Mechanical Lug Carbon Fibre Shafts

For high speed and/or heavyweight applications requiring maximum torque capacity and minimum vibration.
Mechanical design provides the most powerful gripping force possible.
Activated by turning a crank (or impact wrench) that is inserted into the end of a journal.
Requires just five cranks for full expansion – lugs rise concentrically to center the carbon fiber shaft in the core, minimizing the roll bounce common with other types of expanding shafts.
Mechanical and Pneumatic/Mechanical Shafts are also available in traditional steel design.
