Abstract

PURPOSE:To obtain efficiently a high quality curved face mesh and improve its yield, by jetting inert gas of high temperature and high pressure on a plane mesh at the time of forming the plane mesh into a curved mesh. CONSTITUTION:A plane mesh 20 fixed with a supporting ring 12 is mounted on the guide hollow 13 of a forming bed 11, and covered with an enclosing plate 16 through which plural gas jetting holes 17 are bored. Then, inert gas is made to jet through the gas jetting holes 17 of the enclosing plate 16, and, at the same time, it is exhausted through an exhaust pipe 15 by a vacuum pump or the like. Being exposed to jetting inert gas of high temperature and high pressure and being covered with the pressure and the quantity of heat, uniformly on the overall surface, the plane mesh 20 is forced to spread to touch a cavitied portion 14 of the forming bed 11, and a curved face mesh is thus formed.
