Abstract

PURPOSE:To uniformalize the shape of the ink-jetting port of a nozzle and fix the direction of flying of ink by rounding the edge of the ink-jetting end of the nozzle. CONSTITUTION:At the tip of the nozzle 41 the roundness 42 is formed. So as to form this roundness 42, the heat is applied to such a degree that all the head is not influenced thereby after a surface 23 is ground, then the heat is further applied locally only to the part near the surface 23 and thus the edge part at the tip of the nozzle is rounded by melting. By this method, the shapes of edges of all the nozzles in one and same head can be uniformalized.
