<p>The appts. for dispensing hot melt adhesives has an adhesive manifold, the adhesive manifold having an adhesive passageway through it. A heater heats the adhesive manifold, in which it is mounted. A temp. sensor detects a temp. of the adhesive manifold, and is mounted within the adhesive manifold. A re-directing device redirects heat to a first region of the appts. and away from a second region. The re-directing device comprises insulation between the second region and the heater, and may comprise a reflector for reflecting infrared energy, a foil, or an air gap comprising an "L-shaped" slot.</p> |
