100% Carbon-Fiber Expanding Shaft
The Italian technology company Svecom-P.E. has introduced a new patented expanding shaft made entirely of carbon fiber, CF.
The new multi-bladder expanding shaft has three ledges and offers mechanical properties which are unique in the market. A major benefit of the new carbon fiber shaft is that it now allows operators to exceed the usual speed limits for 3’’ core diameters on tissue rewinders, thus allowing them to run at mechanical speeds of over 1200 m/min.
Reach operating speeds four times faster
The new 100% carbon fiber multi-bladder expanding shaft has been specifically designed to meet today’s higher technical requirements on counter-roller rewinding machines. This makes it possible to get very fast acceleration and deceleration times and also reach the operating speed much earlier than traditional shafts. Operating speeds are reached four times faster compared to traditional shafts, consequently increasing the overall productivity. The light nature of carbon fiber also allows much higher maximum operating and peak speeds, with no vibrations from the shaft while achieving them. Critical speeds increase significantly: +98% compared to steel shafts, +119% compared to aluminium shafts, +35% compared to aluminium shafts with carbon inserts (Fig. 1).
