Abstract
Apparatus for dispensing hot viscous liquids such as molten adhesives, either in a continuous bead or as spaced unitary deposits. In preferred form, the apparatus includes a heat exchanger in the form of a fluid manifold which functions to elevate and maintain the temperature of the molten adhesive, just prior to dispensing it, above that temperature level at which the molten adhesive is supplied to the apparatus.
