SETT ATT FORFORMA EN BEKLEDNING FOR ETT SUBSTRAT MED EN KONVEX-KONKAV YTA

摘要

A sheet cladding is closely preformed to a convex-concave substrate by a method including the steps of rough forming the sheet cladding about the substrate so that the sheet cladding closely abuts the convex surface of the substrate while being spaced from the concave surface of the substrate. The sheet cladding, assembled to the substrate, is placed into a rubbery mold which is thereafter sealed and cold isostatic pressure is applied thereto so that the portion of the cladding sheet opposite the concave surface is deformed into the concave surface thereby stretching the sheet cladding to form a tight skin over the substrate.
