Contact Roll

Description of CFRP Contact Roll
Continuously increasing machine speeds and material web widths are requirements which can hardly be met using conventional rolls made of steel and aluminum. The modern design material CFRP is therefore state-of-the-art in our company for rollers which must be able to meet even particularly high-end requirements. For CFRP material, the rigidity-weight-ratio is many times higher than that of aluminum or steel. The critical speed of a rotating body can be increased, and its deflection as well as its mass moment of inertia can be reduced.

CFRP contact roll made of CFRP are available in the same technical designs as our proven metal rolls, and additionally provide the advantages of the modern CFRP material.

CFRP Contact Roll Specifications
(1). Shell material: CFRP (Carbon Fibre-reinforced Polymer)
(2). Contact roll surface treatment: EMDP, NBR, Hypalon rubber covered
(3). Maximum length: 13000mm
(4). Maximum speed: 2000m/min

CFRP Contact Roll Advantages
(1). Improved Stability: CFRP contact roll for Winding have low inertial forces, which allows them to maintain stability even at higher speeds compared to steel or aluminum rollers
(2). Higher Speeds: Due to their low inertial forces, CFRP contact roll can reach higher speeds, resulting in a more efficient rolling process.
(3). Reduced Stresses: CFRP contact roll For Winding reduce stresses on Motors and Bearings, leading to increased life and efficiency.
(4). Light weight: CFRP contact roll for winding are significantly lighter than steel rollers, reducing handling and safety issues during changeovers.
(5). Energy Efficiency: The lightweight nature of CFRP contact roll reduces energy consumption.
(6). Faster Acceleration: CFRP contact roll can speed up significantly faster than steel rolls.
