<p>A deformable medium-dense material layer (12,12') is applied on each side of a surface element (1). The surface element together with the deformable layers is inserted between molds (3,4). The pressure is applied on deformable layer (12) of the inserted surface element at a predetermined temperature by introducing a fluid between deformable layer (12) and mold (3). A cavity (9) is formed in surface element together with the deformable layers by application of the pressure in conjunction with mold (4). Independent claims are included for the following: (1) device for processing breakthroughs of surface element; and (2) sound insulation for lining of aircraft engine.</p> |
