ABSTRACT:
A process and apparatus are described wherein a honeycombed sheet of plastic is extruded from an extruder and at least one protective film of plastic is joined onto at least one of its surface layers, the protective film having a softening temperature lower than that for extruding the sheet. The protective film, combined with the auxiliary film or support film, is laid onto the surface of the sheet leaving the extruder; then the sheet, protective film and support film are subjected to the calibrating and cooling stage; and lastly the support film is separated from the sheet. The protective film has now been made an integral part of the sheet, thereby to produce, for example, a protected honeycombed sheet.
