摘要： PURPOSE:To increase the rate of impregnation of a fiber layer with a resin and to improve the rate of production of a fiber-reinforced plastic by pressing a resin into a sheet by pressing or clamping with an endless belt having a rugged pattern. CONSTITUTION:A laminate prepared by laying a sheet 2 comprising a reinforcing fiber on a resin film 1 applied to a release paper and further applying a release film 3 to the surface is heated on the surface of a heating drum 4, and when the resin becomes flowable, the resin is infiltrated into the fiber layer of the sheet 2 with an endless belt. As the endless belt, a belt (tube belt) having a sealed space to or from which a fluid can enter or leave in its inside and being capable of giving a pressure to the surface when a fluid enters the endless belt is used. When this tubeless belt is used, the belt is provided with a rotary body having a strong central shaft in position 6-1 as a support and a fluid is introduced into the inside of the tube belt to exert a pressure on the sheet surface by the cooperation of 6-1.
