Carbon Fiber Rollers

 Rodillos Duran Converting

Rodillos de fibra en Duran ConvertingCarbon fiber rollers (composite rollers) are designed for reduced weight and high critical speed.

Lightweight, low-inertia idler rollers allow faster web speeds, reduce vibration, decrease waste, and improve product quality.

This high-tech material offers clear benefits over traditional steel or aluminum shafts, including light weight, higher critical speed, reduced vibration, less deflection, and faster line speeds.

Similar benefits are evident when carbon fiber rollers replace traditional steel or aluminum rollers. With carbon fiber rollers in place, machines can run at faster speeds and the web is far less likely to drag and get damaged.

These improvements in shaft and roller performance directly affect productivity and increase machine throughput.

The working speeds are growing steadily and the machines for the converting of the plastic film have reached considerable widths; the resource of the rollers in carbon is therefore a necessity.

This is because the metal rollers are not in degree to maintain the speed-critical requested and may enter in vibration, when brewing hazardous destructive phenomena throughout the implant. The rollers for this machine have to be very rigid and lightweight and the critical speed of the roller, except specific cases of operation hyper-critical, will have to exceed the speed of exercise of at least 30 %.
The roller in carbon is extremely advantageous from lights of 2.5 m, and on tables of 5 m., arrives to weight values and critical speed unthinkable by other materials.

The importance of idler rollers (idler rolls) with low rotational inertia Lightweight, high-stiffness carbon fiber rollers exhibit lower inertia to acceleration and deceleration (rotational or translational), and can run at higher speeds. Composite rollers reduce waste while increasing productivity and efficiency. Carbon fiber idler rollers provide better performance than traditional steel or aluminum rollers, particularly when wide web widths, heavy loads, and faster speeds are necessary. Consider this example where a 164 inch steel roller with an 11.25 inch O.D. was replaced with a carbon fiber roller with the same dimensions:







Carbon fiber rollers can be coated with most of the same materials that metal rollers can be coated with. Many standard coatings are available (shown below), but please ask if you want a specific type of coating.

Dura-Stat: STANDARD COATING. Wear resistant, conductive polyurethane which works to prevent buildup of static charge on rollers. Suits most idler roll applications. Economical, resistant to most chemicals and abrasion, repairable, and replaceable. Black in color with an appealing satin finish. Surface Finish: 32 µin Ra (0.8 µm Ra).

915D: : Thermal spray of nickel chrome with release provides wear resistance, traction and liberation, all in a single coating. This coating has given excellent results in many applications with web materials coated adhesive. The release agent of silicon in this coating prevents even aggressive adhesives is small. Finished the surface 215 µin Ra (5.5 µm Ra=; hardness Rc 58; Color: silver gray.

PC60331: Plasma spray of chromium oxide, offers a ceramic surface with a hardness of stone that has an extreme resistance to abrasive and chemical attack. This coating can be polished to approximately 10 µin Ra (0.3 µm Ra) when they go to work web sensitive materials. Standard of the finished surface: 61-300 µin Ra; Hardness Rc 60-70; Color: Black-dark-green.
