Abstract
PURPOSE:To manufacture easily a formed product that has a radial or concentric color pattern by mounting a rod valve provided with a plurality of channels for supplying molten resins that have different colors to the main body of a nozzle so as to allow the rod valve to be driven, rotated with freely adjusted speed. CONSTITUTION:Flow channels 18A and 18B that communicate respectively with L-shaped flow channels 14A and 14B formed in the main body of a nozzle are formed in the front end of a rod valve 16, and a mechanism to control the driving rotational speed for the rod valve 16 is provided in the rear end of the rod valve 16. If injection is performed with the rod valve 16 stopped, resins of different colors are injected from the flow channels 18A and 18B and a product in which different color resins spread radially is obtained. If injection is made with the rod valve rotating, a product in which different color resins spread spirally from a center is obtained. With the control mechanism to control the rotating speed of the rod valve 16, different color patterns can be obtained.
