Title: Manufacture of articles that include thermosetting powder coatings
Inventor: LEACH ROGER JOHN
IPC: C08L67/06
Filed: 1992-02-07
Abstract: In manufacture of a glass architectural panel (Fig 1) and aluminium foil (4) is bonded to a glass sheet (1) via a layer (2) of thermosetting polyester powder coating material. The powder is deposited (12) on the foil as the foil unrolls (11) and is melted (13) to provide a fused layer (2) which is then cooled (14) to solidify the layer and arrest progress of curing. The solidified layer is sprayed (15) with a silane adhesion promoter, before being heated momentarily to enable the foil with its adhering and solidified, by uncured, layer, to be rolled up for storage (16). The rolled foil is transferred nearer (17) to a float-glass production line (18), where, after being heated to allow it to be unrolled, it is fed onto a hot glass sheet (1) emerging from the line (18). The fused layer melts as it is brought down with the backing foil to contact the glass sheet (1) 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 metalization 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).

As shown, the cabinet has insulated outer and intermediate walls and a heat conducting inner wall. The nozzles 46 and 48 are formed of slatted or honeycomb assemblies 56 and 58 which act as flow smoothing means to produce substantially laminar flow air curtains having speeds preferably in the range 100-400 feet per minute. The inner curtain 60 is refrigerated while the outer curtain 62 forms a guard curtain. For defrosting the evaporator 50 the shutters or valves 84 and 90 are moved to close the main inner passage so that the fan 52 blows ambient air across the evaporator, the refrigerator compressor being stopped. Defrosting may be accelerated by adding a heater in the inner passage just upstream of the fan 52 and/or by passing warm refrigerant through the evaporator direct from the compressor, these additional means also causing defrosting of the nozzle assembly 56 at the end of the main defrosting operation. If these means are not used, a small flow of air is allowed past the shutter 90 during defrosting and is heated by a low power electrical element in the passage 38 just upstream of the nozzle assembly. Protection of the storage space during defrosting of the main evaporator may be provided by having an auxiliary evaporator in the passage 40, which is supplied with refrigerant only during defrosting. A modified construction (Fig. 2, not shown) includes an additional guard curtain outside the curtain 62.
