Abstract
PURPOSE: To economically manufacture a screen of good quality by means of a simple process, by layering in one body in order of a light permeable diffusion film and a light permeable film, on the light permeable resin sheet by means of extrusion molding.
CONSTITUTION: A light permeable resin sheet A is extruded from the extruding machine 1 through the sheet molding die 2, at the same time a light permeable diffusion film B and a light permeable film C are fed onto the sheet A, subsequently, the light permeable resin sheet A which is extruded and still in a semi-melting state, and said films B, C are pressed into one body by the rolls 3, 4, 5 of three roll structure, and after that, it is cut off to a desired size by the cutter 7 through the drawing rolls 6, 6, and it is made a screen. In this regard, said light permeable diffusion film B and the light permeable film C can be fed after the rolls 3, 4, 5 of three roll structure.
