Basic process:
Upper winding trolley → unwinding machine→ unwinding scraper→ front S tension roller→ hydraulic shearing → seam welding machine→ tension measurement roller→ second roller leveling machine (including anti-wrinkle roller→ tension measurement roller→ thickness gauge→ lubricating device→ hydraulic shear→ waste collection hopper→ rear S tension roller→ steering guide plate→ winding machine→ unwinding trolley
