Beschreibung
Zusammenfassung:	A heated air manifold (10) of reduced physical dimensions for heating process air for use in dispensing heated liquids, such as hot melt adhesives. The heated air manifold (10) includes at least one heating element (12) and an air plenum (17,19) having an air inlet and an air outlet. The dimensions of the air plenum (17,19) are optimized for providing a compact heated air manifold (10) for use in various adhesive dispensing systems, such as systems assembled from modular adhesive manifold segments, while retaining the ability to heat the process air in the air plenum to a desired application temperature. The heated air manifold (10) may include a thick film flat heater disposed in the air plenum. The air plenum (17,19) may have multiple individual segments winding throughout the volume of the heated air manifold.
