Abstract
A method for heating and press-forming a plied material sheet prepared by impregnating a thermosetting resin into sheets of parallely disposed plastic fiber or into sheets of woven fabric of plastic fiber. The material sheet is formed into an operation which repeats the steps of heating and press-forming such material sheet within a shaping mold on a heating and press-forming apparatus for a predetermined time period and then releasing the pressure for a predetermined time period while step-feeding the material sheet over a predetermined distance for a time period less than the time period of such released pressure.
