The TRANFOVIA Pressboard Cylinder Rolling Machine pre-forms flat electrical pressboard into arcs and cylinders before joint bonding. Its upper and lower rollers, drive system, electrical controls and dedicated large-diameter support mechanism provide a focused solution for transformer insulation workshops rather than general metal plate rolling.

| Main Function | Mills the pressboard edge into the required bevel for lap joining. | Rolls flat insulation pressboard into an arc or cylindrical shape. | Applies heat and pressure to bond the prepared pressboard cylinder joint. |
It is used to pre-form flat transformer insulation pressboard into arc and cylindrical shapes before the cylinder joint is glued, pressed and bonded.
The stated processing range is 1-8 mm.
The stated cylinder diameter range is Φ300-Φ3500 mm.
The standard workpiece length range is 1500-4000 mm, and the length can be customized around the project requirements.
The standard product description lists an electrical control panel with forward, reverse, jog, continuous rotation and roller-lowering controls. CNC control should not be claimed unless it is separately confirmed for the offered configuration.
The rolling machine creates the curved cylinder form. The cohesion machine is used later to heat, press and bond the prepared cylinder joint.
