    Abstract: PROBLEM TO BE SOLVED: To solve the following problems: that in a die for molding a multilayered cylindrical resin by sequentially laminating a plurality of cylindrical resins in the die, the resin is not filled into a flow passage on the side opposite from a resin injection port, consequently the resin lacks at a part of the cylinder in the circumferential direction and a portion not developing the characteristics of the resin is caused, and even if the resin is filled, sufficient durability can not be obtained due to weak fusion force of an interface; and that for increasing the number of the layers in a feed block for molding a multilayered sheet and film using a single layer T-die, the expensive feed block of complicated structure is needed.SOLUTION: The resin is injected so as to split the circumference of an annular flow passage, the interface where the cylindrical resins are in contact with each other and the resin layer are spirally expanded to supplement the lack part of the resin, the adhesion strength increases with the increased adhesion area, and at least one of a nozzle and a mandrel of the feed block is rotated in order to increase the number of the resin layers.
