Abstract
To manufacture a jet nozzle, the nozzle plate is first drawn through a drawing ring of spring steel in one operation by a press and punch die having the internal dimensions of the jet nozzle, the plate subsequently being punched during further drawing in a hard elastic plastic block which serves as a cutting cushion. The drawing ring is then slightly pressed into the plastic. All parts of the press and punch tool which are subject to the pressure exerted by the die and the die itself have been polished to be free from hair lines.
