Automatic adjustable nozzle systems

摘要

The invention provides a sealant applicator machine for dispensing sealant onto an insulating glazing unit. The insulating glazing unit may include two panes separated by a spacer having a spacer width. The sealant may be dispensed around a periphery of the insulating glazing unit. In certain embodiments, the sealant applicator machine includes both a fixed width sealant-dispensing head comprising a fixed width dispensing nozzle, and an adjustable sealant-dispensing head having a plurality of adjustable dispensing nozzles. The fixed width sealant-dispensing head and the adjustable sealant-dispensing head may be operably coupled to one or more sealant supplies.
