PURPOSE: To compress the convex side of strain to correct the strain in a method and device for post processing to correct strain of a multilayer plastic laminate with an additional layer of a different material such as paper etc. CONSTITUTION: Plates 31, 33 each with a curved parallel face 35 are heated by heating means 30, 34. The lower plate 33 on which a laminate sheet 27 inserted through an inlet port in a condition the convex side is directed downward is laid is driven upward to press the sheet 27 against the upper plate 31. After forming under a prescribed pressure, the lower plate 33 is detached, in a condition the sheet 27 is laid on, from the upper plate 31 and cooled down. After the cooling, the sheet 36 is discharged in a condition being formed by the plates 31, 33. |
