Continuous preheat and tacking ovens to allow for proper de-airing of windshields and to tack the glass for further processing in the autoclave. Glass temperatures exiting the preheat are 100-120°F and exiting the tacking oven at 170-180°F.
Cooling systems utilize ambient or chilled air, depending on required glass exit temperatures. Air impinges on the product from above and below through high efficiency nozzles, which minimizes the capacity of the cooling blowers.
For windshield applications, PVB is preheated prior to stretching to contour the shape of a windshield. PVB can be stored in low moisture rooms on multiple roll storage devices, to condition the moisture content prior to use
