摘要： PURPOSE:To obtain a molded article with little difference in mechanical strength in the axial direction and in the circumferential direction and enable to stop temporarily feeding of a material to unnecessary parts such as an aperture by arranging a defoaming roller either in front of or back of a material feeding apparatus in the rotating axis direction on the inner face of a cylindrical frame. CONSTITUTION:A defoaming roller D is arranged either in front of or back of a material feeding apparatus C in the rotating axis direction on the inner face of a cylindrical frame A to perform impregnation and defoaming of a cut reinforceing fiber 5 fed from the material feeding apparatus C and a resin compsn. and defoaming is performed while the defoaming roller D is brought into contact with the inner face of the cylindrical frame A and is rotated. In addition, the defoaming roller D is freely rotatably supported on a rotating plate 13 and the rotating plate 13 is rotated in the horizontal direction by rotating a bar 12 for rotation being rotatable in the horizontal direction. In addition, the material feeding apparatus C is not supported by means of the rotating plate 13 and is fixed at the position. Therefore, the feeding direction of the reinforcing fiber 5 and the resin compsn. can be changed in the reverse direction by rotating half the rotating plate 13.
