Abstract
In a resin coating applicator, a holder 14 is fixed on a base 15 fitted to a drawing machine, and in the holder 14, hot water can be circulated from an inlet 18. The inner circumferential surface of the holder 14 is formed into a tapered shape so that the outer circumferential surface of a cup-like member 4 of a cartridge type coating sub-assembly 1 is fitted to the holder 14. The respective outer circumferential surfaces of a nipple 2 and a coating die 3 are cylindrical so as to be fitted to the inner circumferential surfaces of an inner cylindrical member 6, and they are positioned by a step portion. Further, they are pressed from the upper and lower sides by the bottom portion of the cup-like member 4 and a lid member 5. The lid member 5 is fastened to the cup-like member 4 integrally by a thread.
