1455588 Multiple glazing unit manufacture SAINT-GOBAIN INDUSTRIES 19 Dec 1973 [21 Dec 1972] 58756/73 Heading C1M Apparatus for making multiple glazing units comprising at least two transparent glass sheets separated by a strip of plastics material at their peripheries comprises a first longitudinal transporter 8, 10, 11 such as endless belts C and rollers G, to transport successive glass sheets V to an assembly station M; a second longitudinal transporter 13 to carry the sheets past an extrusion station N at which the strip of plastics material is applied to the upper surfaces of the sheets; a first transverse transporter 12 such as a pivotable fork connecting the first and second longitudinal transporters 11, 13 and arranged to remove some of the sheets from the first to the second transporter upstream of the extrusion station N; a second transverse transporter 15 connecting the first and second longitudinal transporters 11, 13 and arranged to remove sheets from the second transporter 13 downstream of the extrusion device N and transport them to a first tilting device 16 arranged to invert them through 180 degrees before depositing them on the upper surface of another sheet at the assembly station M; a third longitudinal transporter 18 to transport the assembly of glass sheets from the assembly station M to a finishing station S and automatic means, such as angled rollers 91 and edge rolls 92 for positioning the sheets V on the longitudinal transporters and the first tilting device. The inverted sheet from tilting device 16 is deposited on a sheet having no plastics edge strip which is positioned on transporter 11 over a second tilting device 17 which raises the assembled sheets through just over 90 degrees to be on edge on rollers 181 and supported on transporter 18. The assembled sheets are heated by a radiant heating panel 19 and passed between pressing rollers 20 to form the seal. The sheet then continues to station S where an elastomeric silicone is injected into the joint (e.g. using the injection of Specification 1,418,565) and applies the adhesive ribbon. For forming a tripple pane two sheets carrying the plastics strip are attached one on either side of a plain sheet by the apparatus described in connection with Fig. 4 (not shown). |
