PURPOSE:To provide a method for extrusion molding of a synthetic resin sheet capable of regulating finely glossiness of the side face of the synthetic resin sheet without exchanging an embossed cooling roll when the glossiness of the side face of the synthetic resin sheet is decreased with the embossed cooling roll by a method wherein the embossed cooling roll is used as one cooling roll of a cooling roll group which carries out cooling just after extrusion in extrusion molding of the synthetic resin sheet. CONSTITUTION:In a method for molding a synthetic resin sheet wherein band- like resin from an extrusion mold 2 is passed through a cooling roll group 3 of three rolls in one set of which one cooling roll 32 is made an embossed roll to decrease glossiness of its one side, a relative position between the embossed cooling roll 32 and another cooling roll 33 adjacent thereto is adjusted to control the glossiness of one side of the synthetic resin sheet. |
