Abstract

1457686 Casting plastics films and plates on glass ribbon SAINT-GOBAIN INDUSTRIES 8 Nov 1974 48436/74 Headings B5A and B5B [Also in Division B2] Sheets of transparent plastics of high optical quality are cast from hardenable liquid compositions by depositing a layer 18 of the composition on a continually horizontally moving ribbon 30 of glass, allowing the composition to harden, and stripping it from the glass. A glass ribbon 30 is made by the float glass process and fed directly by support rollers 2 through a cooling unit 3, a washing device 4, and a dust-free enclosure 6 through which filtered air is passed. One or more layers of a plastics melt solution, or reacting mixture are deposited by slit coating heads 17 (Fig. 1) or 40, 41 (Fig. 2, not shown) after a release agent has been applied to the glass. Heaters 11-14 maintain the glass and the plastics at a temperature suitable for curing the plastics. The sheet is removed around rollers 19-21 and covered by protective layers 24 before rolling up. A coating of adhesive or colourant may be sprayed on to the sheet which may be used in windscreens.
