This invention relates to a process and a device for production of plastic sheets of high optical quality, used particularly in laminated glasses. According to the invention, a liquid mass is applied to a plane mobile support consisting of a horizontally taut flexible strip, this flexible strip passing over two horizontal and longitudinal rectilinear supports, contact of each with the flexible strip being limited approximately to a generatrix, these two supports extending over the entire length useful for production and being placed along the side edges of the strip, this latter being stretched crosswise on these two rectilinear supports like a drumhead. |
