摘要:
A process for assembling portions of an aeronautical wing, wherein a wing covering (8) is assembled with carrier structural elements (10, 11, 12), allows the simultaneous application of all filling tapes on an exposed surface, by speeding-up and making more reliable the process itself, and it comprises the steps of: placing side by side the structural elements (10, 11, 12) longitudinally, to form the spars, by determining a flat surface (20), having a plurality of longitudinal junctions, faced upwards; adhering to said longitudinal junctions respective filling tapes (19); translating and rotating by 180° said structural elements (10, 11, 12) in one single solution, by keeping them fixed in the mutual positions thereof and by transferring them above an inner surface (13) of a wing covering (8); and translating said structural elements (10, 11, 12) in one single solution, by keeping them fixed in the mutual positions thereof, downwards, by making the flat surface thereof (20) to coincide with said inner surface (13).
摘要:
The present invention concerns a method of producing an insulation product comprising a board of porous insulation material wrapped in a gas-impermeable foil, said method comprising the steps of providing a succession of porous insulation material boards on a first conveyor apparatus and feeding the boards on a second conveyor apparatus; providing wrapping foil and wrapping said foil to form a tube around the boards on said second conveyor apparatus, flushing the boards with an insulating gas, and sealing the wrapping foil at the ends of each board transverse to the direction of travel of the second conveyor apparatus.
