<p>A method of gluing a transparent film onta a support having a window in it, is characterised by the fact that the film is coated over the whole of the surface of one of its sides with a thin layer of glue containing heat sea1ing products and a hardener. The film is applied then pressed on the outer face of the support. The product of this method is characterised by the fact that the film has glue distributed over the whole of its surface which makesit possible for it to be applied onto the support with a window in it, to adhere to the solid surface of the said support, and to form a perfectly transparent window in the support. The heat sealing products ensure the adherence of the film on the solid part of the support, and the hardener ensures the polymerisation of the layer of glue at the leuel of the windows.</p> |
