Industrial rollers for the converting industry. The converting industry “converts” specific raw materials into a different form. Example: pulp into paper, aluminum into tin foil, plastic into cellophane, etc.
Previous Limiting Technology
Steel and/or aluminum cylindrical tubing.
Cylindrical shafts needed to be stiffer and lighter to enable higher throughput speeds without experiencing adverse deflection and subsequent harmonic vibration. Added benefit would be extended fatigue life.
High modulus carbon fiber/epoxy composite tubing approaching stiffness of steel (25 MSI) combined with an externally bonded thin steel wear surface. Created a truly “composite” solution combining the best properties of FRP composites in conjunction with metallic features.
