Abstract
In a working nozzle for a gel coating apparatus, a nozzle plunger (15) has, in addition to a valve portion (15b), located at its lower end, for opening or shutting the small-diameter portion of a plunger insertion hole (4), a flange (16) which is located above the valve portion and can be brought into contact with or separated from an edge of the small-diameter hole portion (5). This prevents leakage of gel during shutting of the small diameter. The nozzle plunger has also a gel accommodating groove (17) provided on the outer periphery of said valve portion and adjoining to a lower surface of the flange, thereby permitting the sharp cutting of the gel when the valve shuts. The nozzle plunger has a step (25) provided at the lower end of its inner periphery and having a larger diameter than larger than the inner diameter of the valve portion, thus preventing stagnancy of seeds within the nozzle plunger.
