PROBLEM TO BE SOLVED: To improve an operation method for variably feeding a molding material and improve the structure of a metering feeder and a molding machine linking with each other. SOLUTION: The feeding amount of the molding material (a) is divided into the feeding patterns of different feeding amounts to compose one cycle, and by repeating the cycle, the molding material is quantitatively fed in the heating cylinder 12 of the molding machine 11 in a liquid saturated state to build up the operation method for molding material feeding. The molding apparatus has a recess 3 having an opening end on the cylinder inner wall face 5a of a perpendicular wall face 5 facing the hopper outlet 1a of a molding machine side cylinder end portion 4 in the metering feeder 2, the molding machine side cylinder end portion having an axial length S of twice the flow path width (w) between adjacent blades 6a of a metering feeder screw 6 and a winding type 14, plate type 15 or Dulmage type-like kneader 19 replacing a part of a carrying blades 18 so as to be a weir for a flow path 9 between the carrying blades 18, selectively formed on the intermediate region of a screw straight barrel of the molding machine. Further, the apparatus is provided with a means for viewing its inside when needed. COPYRIGHT: (C)2005,JPO&NCIPI
