A heater assembly (20) for a hot melt applicator includes a heating block (24) having a melting chamber (26) and two compartments receiving a pair of elongated heating elements (36, 38), along opposite sides of the chamber. The heating elements (36, 38) have respective longitudinal axes (44, 46) that lie in a common plane (48) which extends toward an outlet (30) of the melting chamber at an angle (56) relative to a central axis (32) of the melting chamber. In preferred forms, the longitudinal axes of the heating elements converge toward each other as the outlet of the melting chamber is approached. |
