Whereas conventional driving rolls can achieve transfer of amorphous ribbon, whether or not transfer is smooth and safe depends on control of the gap between rolls. If the gap between the rollers is too large, the friction force between the driving roller and the amorphous strip is insufficient, and the amorphous strip is not driven to advance; if the gap between the rolls is too small, the surface of the amorphous ribbon will wear and even "sticking" will occur.
In addition, because the gap between the rollers is easy to change due to the influence of long-term vibration, abrasion and other factors, and the amorphous strip is conveyed by the gap between the rollers with high precision, a mechanism for monitoring and adjusting the gap between the rollers in real time is needed at the present stage to ensure the stable and safe conveying of the amorphous strip.
