The core technology of the rewinding machine:
Tension control: Full closed-loop control:
Modern models adopt multi-segment closed-loop tension control, which is fine-tuned in real time through sensors and servo drives. It is recognized as the "soul technology" in the industry. It is used to ensure that the material does not deviate, wrinkle or stretch at high speed, and is compatible with different materials ranging from brittle films to elastic non-woven fabrics.
Automatic Deviation Correction (EPC) : CCD vision
The position is monitored by CCD/edge sensors, and the deviation correction roller is driven for correction in milliseconds to ensure that the slitting line is straight and the winding end face is neat, which is a prerequisite for high-speed production.
Automatic winding and changing: surface winding, center winding, gap winding
The double-station rotary frame/shuttle car enables automatic splicing and switching between new and old rolls, ensuring continuous production and significantly enhancing OEE (Overall Equipment Efficiency).
