Abstract
PURPOSE: To manufacture a stable spinnevet having a high dimensional accuracy, by extruding an unpenetrated spinning orifice from the back of the plate with a hollow on the front side to form a protrusion and to pass through the orifice.
CONSTITUTION: One side of the spinning plate 1 is bored by the drill 2 to form the hole 2, and the other side is ground by a surface grinder to form the hollow 4 with the periphery 1a left, and to give the unpenetrated part 3 between the hollow 4 and the hole 2. The bottom of the hole 2 is extruded by a punch or press outward to form the protrusion 7 and the orifice 9. The tip of the protrusion 7 is lapped and ground to penetrate the orifice, taking the top 1a of the periphery as a reference surface.
EFFECT: Cleaning of attached foreign matter is possible without requiring skilled workers.
