An apparatus is disclosed for degassing a multi-ply assembly (7) comprises a frame (1) carrying a flexible, substantially impermeable membrane (6, 8) which is movable into position to cover the assembly while the latter occupies a predetermined area of a surface of a supporting structure (3) thereby to form an envelope enclosing at least the edges of the assembly to form an edge space in gas flow communication with spaces between plies of the assembly. Aspirating means including a passageway (14) are provided in gas flow communication with the interior of the envelope at its periphery for aspirating the edge space and thus degassing the inter-ply spaces of the assembly. Heating elements (5, 9) are also provided in such a way that heat is dissipated at a greater rate over a central region of the predetermined area than it is over a peripheral region of that area. The apparatus has the advantage that a multi-ply assembly may be easily and rapidly inserted therein for degassing. <IMAGE> |
