PURPOSE:To perfectly perform washing within a short time, by providing a washing port for supplying a washing fluid to a groove to a head main body at a position displaced to the axial direction of a rotary shaft with respect to a stock material emitting port and moving the rotary shaft to the axial direction. CONSTITUTION:A piping connection port 4 of a main agent A1, a liquid leakage preventing packing 9, the emitting port 6 of the main agent A1, a connection port 5 of a curing agent B1, a packing 10, the emitting port 7 of the curing agent B1, an N2-gas emitting port C1 for washing, an emitting port of a detergent D1 and a washing groove 12 washing the groove 3 of a rotary shaft 2 are arranged to a head main body 1. At the time of mixing and injection, the rotary shaft 2 is raised to the direction shown by an arrow P and the upper end part of the groove 3 of the rotary shaft is allowed to coincide with the parts of the emitting ports of the main agent A1 and the curing agent B1. Next, when the head main body 1 is rotated at a high speed, the main agent A1 and the curing agent B1 are scraped into the groove 3 to be mixed in a laminar form and injected from an injection port 15. |
