Colibri rings

The ultimate spinning ring solution for fine and super fine counts is now available thanks to COLIBRÌ, the product developed as requested by the most demanding customer. Fine and super fine counts require a special ring surface to run at the maximum speed with lowest possible yarn breakages. The COLIBRÌ ring obtains this result thanks to the combination of 75+ years experience of PROSINO-BORGOSESIA RINGS and the state of the art non metallic coating.
