PCT No. PCT/GB90/01286 Sec. 371 Date Feb. 14, 1992 Sec. 102(e) Date Feb. 14, 1992 PCT Filed Aug. 14, 1990 PCT Pub. No. WO91/02648 PCT Pub. Date Mar. 7, 1991.In manufacture of a glass architectural panel (FIG. 1) an aluminium foil is bonded to a glass sheet via a layer of thermosetting polyester powder-coating material. The powder is deposited on the foil as the foil unrolls and is melted to provide a fused layer which is then cooled to solidify the layer and arrest progress of curing. The solidified layer is sprayed with a silane adhesion promoter, before being heated momentarily to enable the foil with its adhering and solidified, but uncured, layer, to be rolled up for storage. The rolled foil is transferred nearer to a float-glass production line, where, after being heated to allow it to be unrolled, it is fed onto a hot glass sheet emerging from the line. The fused layer melts as it is brought down with the backing foil to contact the glass sheet and fulfil the cure of the powder material so as to establish the bond. Instead of a single foil, several may be provided overlapping one another (FIG. 3). Decorative effects can be obtained using different pigmentations of powder and partial metallization of the glass (FIG. 4). The technique of interrupting the cure is applicable to provision of a glass window (FIG. 5) and a glass laminate (FIG. 6). |
