Production Overview The HF‑L2003 real‑time monitoring copy‑type warping machine is newly‑developed high‑performance warping equipment. It is equipped with high‑quality closed‑loop tension control system (PID) to guarantee stable and precise yarn sheet tension. Its microcomputer control system continuously monitors pan head diameter, meter count and circumference during warping process, real‑time adjusting tension to ensure consistent outer circumference and meter length of
