Abstract

PURPOSE:To apply painting material on the outside of a tube in uniform thickness, by cooling a melt-extruded plastic tube with the mandrel regulating an inside diameter, then passing through a specified painting material bath and controlling a thickness by a circular elastic object. CONSTITUTION:Plastics raw material is kneaded by an extruder 1, and a tube 3 is extruded through a crosshead die 2, cooled, solidified along the mandrel 4 which is cooled by the cooling pipe provided with a water suction port 5 and a water discharging port 6 and taken up by the take-up rolls 7, 7'. At the same time, the ink which flows out from an ink pot 11 and overflows the inside wall 10 of a jecket (an ink well) 8 is applied to the outer face of the tube 3, and uniform coloring is given by squeezing with the 0 ring 9 provided at the intermediate position of the inside wall 10, then a colored (painted) tube 14 is obtained via take-up rolls 7, 7'.
