With the development of POY (Pre-oriented Yarn) and the increase in bobbin size, new handling problems arise. A happy intuition leads to the development of a system for loading and unloading creel carts on draw-twisters. The solution meets with immediate success and is adopted by the main manufacturers (Rieter – Barmag – Zinser – Marzoli – Ishikawa – Sant’Andrea – etc.), as well as purchased directly by drawn yarn producers.
More than 500 of these systems and around 12.000 carts are fabricated during the years from 1966 to 1972. Many of these systems are still fully functional around the world today.
