This was made possible using strong rolls with high closing force and an exceptional control of thermoregulation flow rates.
After the calendering stage the PC sheet, co-extruded with an anti-UV layer, passes through a controlled softening oven before entering the shaping stage which consists in a metal alloy rolls stack. Rolls are thermically controlled and shaped according to the contour design required for the sheet.
The shaping assembly can be easily dismounted to allow a prompt substitution of the rolls. The line is completed with a special haul off unit, easily adaptable to the different sheet contours, and a cut-off group with automatic stacker which facilitates placing the sheets on suitable platforms, ready for shipment.
