Description

  

  Procédé pour protéger un film dispositif     contre    la formation des anneaux de Newton    Le but de la présente invention vise la suppression  des anneaux de Newton qui se manifestent lors de la  mise sous verre des     films    dispositifs photographiques.  



  Les traitements actuels consistent à donner une cer  taine rugosité à la     surface    des verres qui sont en contact  avec le film dispositif, ce qui s'est montré insuffisant  lorsqu'on veut fixer le     fihn    dispositif sous une pression  de 1     kg/cm2    environ, car le film dispositif est relative  ment souple et, en épousant à nouveau le verre dans  tout son relief sous la contrainte de la pression, les  anneaux de Newton réapparaissent à nouveau.  



  Le procédé selon l'invention est caractérisé en ce  qu'on dépose une buée de fines gouttelettes de vernis  à la surface du film     dispositif.    Ces gouttelettes peuvent  former une rugosité relativement fine à la surface du  film. Les gouttelettes, en se     posant    sur le     film    souple,    forment sur ce dernier une assise relativement large et  constituent contre le verre de protection de petits monti  cules sous forme de pointes. Dès qu'une pression est  exercée sur le verre, les monticules de vernis, reposant  sur une assise plus large, ne se laissent plus enfoncer  dans le film dispositif souple et les anneaux de Newton  ne peuvent pas se former.



  Method for Protecting a Device Film Against the Formation of Newton's Rings The aim of the present invention is to eliminate Newton's rings which appear when film photographic devices are placed under glass.



  The current treatments consist in giving a certain roughness to the surface of the glasses which are in contact with the device film, which has proved insufficient when it is desired to fix the device film under a pressure of approximately 1 kg / cm2, because the device film is relatively flexible and, by again conforming to the glass in all its relief under the stress of the pressure, the Newton rings reappear again.



  The method according to the invention is characterized in that a mist of fine droplets of varnish is deposited on the surface of the device film. These droplets can form a relatively fine roughness on the surface of the film. The droplets, by resting on the flexible film, form a relatively wide base on the latter and constitute small mounds in the form of points against the protective glass. As soon as pressure is exerted on the glass, the mounds of varnish, resting on a wider base, can no longer be pushed into the flexible device film and Newton's rings cannot form.
