Device that are designed for precision winding and warping operaitons.During the dissolution and winding of the coil material, keeping the same tension all sizes .Material desired tension when set to the device can be operated solvent, wrapper and attractive due to information from loadcell.Precise tension control is made by the PID system. In this way , the material elongation, relaxation and offset printing problems such as printing machines are prevented . Save convenience and time to machine operator with ease of usage.It can work with load cell and dancer potentiometer....
