PURPOSE:To realize a method for manufacture of resin sheet having foaming capability wherein a solid sheet which is excellent in surface conditions and smoothness can be manufactured. CONSTITUTION:A method for manufacture of a resin sheet having foaming capability wherein foamable molten resin extruded from a die is quenched, and made into a solid phase while foaming is being restrained, is so constructed that the molten resin extruded from the die 1 is introduced into refrigerant solution 4 filled in a refrigerant solution bath 3 provided just under the die 1, cooled, and then made to pass a pair of pinch rolls 11, 12 provided by being thoroughly dipped near a surface of the solution. |
