Coil winding tensioner Electronics Tensioner is newly developed by Kimchen. By the electronic system and non-contact breaking edsign.there is barely any contact in the core mechanism of the main tension wheel,except the connecting bearing. This combination provide smooth,stable and consistence tension provide smooth,stable and consistence tension,even in high speed winding.The non contact designs also reduce wear and tear of most of the critical components as to cut down maintenance cost.
