Advantages of the carbon fiber rollers

Higher speed and lower weight 

Carbon rollers for converting machines normally achieve twice the critical speed of the corresponding steel rollers and weigh 10-15 times less.

Wider formats
Due to the stiffness and lightness of carbon the film working formats can become wider and increase the production.

Lower starting time 

Thanks to the lower inertia, the plant starting time can be overwhelmingly lower with a better efficiency in production.

Many rollers don't need to be powered


Often metallic rollers, due to the weight and lightness of the film they carry, have to be powered and controlled by complex electronic systems in order to avoid stretch or damages. The lightness of carbon is such that even a light film traction can move the roller, saving all cost derived by motors, electronic drivers, control systems and energy necessary to power it.

More precision in load cells
Dancing rollers or every roller installed on load cells, if made of carbon fibre (thus very light) form a lower tare weight. This means that the actual film tension can be read with greater precision and rapidity from smaller load cells

Diameter reduction and higher machine compactness

With carbon fibre the diameters of the rollers can be lowered with a consequent reduction of needed space. In many cases this allows a reduction of the overall dimensions of the machine and results in being more compact and economical.

Improvement of aerodynamical flow


Lower diameters allow to reduce the volume of air dragged by roller motion that at a high speed can cause strong turbulence. The film is therefore less disturbed by turbulence.

Reduction of surface contact

Another advantage of smaller diameters comes by reducing the contact area between film and roller at same angles. This means there are fewer possibilities to damage the film and less interferences during its course.

More design freedom
Lower diameters means more space available and the possibility to decide with a high degree of freedom the input and output angles, roller distances etc. without having to renounce to other design or economical aspects.

Reduction of structural loads on machines

The use of carbon rollers in converting machines does not only increase working speed and the width of material but reduces the loads on the structure that can become lighter and more convenient with less electric power involved.
