Product Detail

Transformer Insulation Paperboard Cylinder Rolling Machine (Thick Cardboard Tube Forming Machine)

YIBO Paperboard Cylinder Rolling Machine is engineered for precision forming of transformer insulation cardboard tubes, delivering exceptional roundness for thick-wall applications. Driven by a robust 3-roller system, the upper roller moves vertically with limit control to prevent slipping, while synchronous reducer and gearbox drive ensure consistent rotation. Rollers are finished with electroplating or polyurethane for surface protection. Our exclusive paper tube supporting mechanism—first initiated by YIBO—facilitates large-diameter rolling with unmatched stability. Processing thicknesses of 3~8mm, drum diameters Φ300~3500mm, and lengths 1500~4000mm (custom non-standard), at a rolling speed of 4.08m/min, this machine is the definitive solution for transformer insulation manufacturers. Backed by YIBO’s 23+ years expertise and global certifications.
