CMT Series Tension Unit
Magnet type tension units
TNK is the original designer of the PATENTED magnet tension unit for coil winding. The tension from traditional friction type tension units can vary after a short time giving inconsistent winding characteristics.
The high quality magnet system in the TNK units ensures the set tension remains constant and stable which improves product quality and overall efficiency. This magnet system works together with the tension bar to prevent any sudden change in the tension when winding non-round shaped coils.
The BC models use a pneumatic cylinder to control the tension bar spring. This is a benefit when working on CNC winding machines where you want to de-tension the wire during terminal wrapping or pull the wire tight for reverse movements.
The various models cover a range of tension values to give fine control of tension adjustment for more accurate setting.
