Abstract

The invention concerns a manufacturing method of a secondary nozzle to produce secondary jets in air looms, of the type consisting of a tubular element open at one end and having a gauged hole in correspondence of the opposite end. According to the invention, said method comprises the following steps: - cutting to size a steel rod and finishing its outer surface with centesimal tolerance; - drilling said steel rod with an axial dead hole of gauged dimensions with centesimal tolerance; and - permanently deforming on a die said drilled steel rod, with flattening of at least one part thereof near its closed end and shaping of this end according to an inclined plane, and subsequently forming a gauged hole on said inclined end surface.
