<p>A process for coating a substrate (10) with a film of thermoplastic material, in which fibres or filaments of the material are applied to the substrate and are melted to form a continuous film. The material may be applied by forming, on a donor substrate (5) a layer of said material in the molten state, applying an electrostatic field between the substrates (5, 10) to draw from said layer a plurality of filaments which are deposited on the receiving substrate (10) forming the film on the receiving substrate by causing said filaments to melt. This process can be used in particular to form very thin films. It is applicable to adhesive materials as well as to thermoplastic polymers. </p> |
