Abstract
The system includes a nozzle, a drive, a metering pump, a supply of material and a controller. The nozzle dispenses material into contact with one or more surfaces of a window sash. The drive relatively moves the nozzle with respect to the window sash along a path of travel defined by a perimeter of the window sash at controlled speeds. The metering pump delivers the material to the nozzle at controlled volumetric rates that correspond to the controlled speeds of relative motion between the nozzle and the sash. The supply of material delivers the material to the metering pump. The controller controls the relative motion between the window sash and the nozzle and controls the flow rate of material dispensed by the nozzle.
