Precise and uniform yarn tension control

Tension-Motion Sensor System

The premier system for quality warp sets with precise tension control and zero lost yarn threads.

The YTC-2000 provides optimal production for warp knit and slasher warp sets, taking care of the two major causes of yarn tension variation: creel length and warper speed. The result is excellent yarn tension control across the warp and throughout beam build with no lost yarn threads.
