Laminater for foaming extruded sheet of foamed insulation board

摘要

PURPOSE: A pasteboard machine is provided to paste polystyrene foam extruded sheets to upper and lower surfaces of foam insulation plate by supplying expandable polystyrene between polystyrene foam extruded sheets. CONSTITUTION: A pasteboard machine includes a sheet extruding device(10) for extruding two polystyrene foam extruded sheets(101). A guide device(30) is provided to develop two polystyrene foam extruded sheets(101) such that a plate feeding space is formed between two polystyrene foam extruded sheets(101). A plate feeding device(40) is provided to supply a foam insulation plate(102) into the plate feeding space(1) formed by the guide device(30). A plate conveying device(50) conveys the foam insulation plate(102) supplied from the plate feeding device(40). The foam extruded sheets(101) is heated by a sheet heating device(60). The foam extruded sheets(101) are pressed and pasted by a sheet pasting device(70). The foam insulation plate(102) is cooled by a cooling device having a cooling roller.
