Our technology
We make carbon fiber rollers according to two patented processes:
- PULLWINDING: is a variation of pultrusion in which fibers settle at various angles. Thanks to this patented technology, Cometec is thus able to obtain higher and more homogeneous mechanical performances than a conventional pultruder, without using expensive textile fabrics.
| ADVANTAGES | DISADVANTAGES |
| It is a process that takes place in a single high thickness cycle | High thicknesses |
| Costs are reduced since the price is obtained from the volume effect Standard sizes | Standard sizes/diameters < 200 |
| Good precision, straightness and tolerances are obtained | Diameters < 200 |
| 3Q: Quality/Quantity/Quotation | Transverse stiffness |
| On request protective film for rubberized rollers |
- K1: is a patented process by Epsilon Composite, used in addition to pultrusion to produce large diameter pieces (> 300 mm), of unparalleled stiffness and lightness. In practice, pultruded rods with very high rigidity are addes between several layers of fiber wrapped around a mandrel, which gives the finished piece a very high rigidity with an optimized mass. This allows you to benefit from the versatility of the filament winding process while retaining the advantage of the exceptional properties offered by pultrusion
