A manufacturing method and a manufacturing apparatus for forming a sheet

Method for producing a molded sheet according to the present invention, by pressing the resin between a pair of rolls mold R1, R2, a method for producing a molded sheet by molding the resin into a sheet, a pair of rolls mold R1, as distance between the rolls between R2 is constant, and adjusting the rotational phase of the pair of rolls mold R1, R2, in a state of being synchronized with respective phases, the pair of roll forming mold R1, the rotational angular velocity of R2 is obtained and a step of substantially the same. Thus, it is possible to precisely control the thickness of the molded sheet.
