包覆角补偿
获得专利的包覆角补偿系统，透过位置感应器及材料张力控制器。由于包覆角会改变，造成测量与实际值有误差，因此需要此信息做张力轮的位置补偿。Patented wrap angle compensation through position sensor and fabric tension controller allows an integrated fabric tension measurement on machines with internal rollers only.
The measuring fault occurring at the stretcher roll because of the wrap angle change is corrected in accordance with the given position.
